ABSTRACT
The main food consumption of farming families is an important concern during the pandemic. Farmers in West Nusa Tenggara (WNT) survive with the availability of rice to support household health and food security during the pandemic. In addition to its nutritional content, rice also contains phenolic compounds and has antioxidant activity. This study aims are to measure the frequency of rice consumption, food variety, varieties of rice consumed daily during the pandemic in WNT, as well as the antioxidant properties of several rice varieties grown in WNT. This study was conducted from September 2020 to June 2021 in East Lombok, Sumbawa and Bima Regencies, WNT Province, Indonesia using a survey approach. The data collection techniques were observation, Focus Group Discussion, recording, interviews with 74 respondents with a semi-structured questionnaire and study literature related to the nutritional content and bioactive compound of the rice. Quantitative data was tabulated to determine the frequency and average then descriptively analyzed, while qualitative data was thematically analysed. The most consumed rice varieties are seen from the production data of seed breeders in the WNT region, the phenolic content was determined using Folin-Ciocalteu, antioxidant activity was examined using DPPH assay. The result showed that the highest portion of food consumed by farmer households in WNT is rice. The most variety of rice produced by breeders is the Inpari 32 variety. There are about 97% of farmers consume rice for 3 times a day, while 3% of the remaining consume 2 times a day of rice. Food variety includes 7.9% vegetable-rice and 92.1% rice-vegetables-meat protein. The results of the analysis of antioxidant properties and phenolic content in rice is depending on the variety. The antioxidant properties of the Jeliteng, Baroma, Pamelen, Nutrizinc and Inpari 32 rice varieties were 44.85+or-0.51%, 9.87+or-1.55%, 9.96+or-1.22%, 9.75+or-1.09%, and 14.305+or-1.24%, respectively, while the phenolic contents were 9.76+or-0.09, 4.23+or-0.03, 4.48+or-0.02, 4.64+or- 0.07, 4.58+or-0.42 mg GAE/g dryrice extract, respectively. The results of this study indicate that rice has been used as one of antioxidants source for farming families during the pandemic.
ABSTRACT
Natural Functional Foods (NFFs) are unprocessed foods with proven health benefits beyond their nutritional value. The Mediterranean Diet (MD) and Mediterranean Lifestyle (MEDILIFE) are well known for their beneficial effects on health. Psychological Resilience (PsyR) is not only an important factor in human well-being;it is also regarded as a key indicator of mental health. The purpose of this study was to explore the relationship between NFFs and the MD and MEDILIFE in Greece, as well as their association with PsyR and other health-related parameters. In a cross-sectional design, 338 healthy adults participated voluntarily in an online research survey. There was a statistically significant association between the consumption of NFFs grown and produced in the Mediterranean region and the MD and MEDILIFE (p < 0.001). When the MD and MEDILIFE associated NFFs scores were summed up to form a 10-item scale (NAFFAME), the NAFFAME had a statistically significant positive correlation with PsyR (p < 0.001) and sleep quality (p < 0.05) and a negative correlation with body mass index (p < 0.001). There was also a statistically significant difference (p < 0.05) between the means of the NAFFAME score on different weight loss diet outcomes. Multinomial regression analysis identified the NAFFAME score as a prognostic factor in maintaining weight loss after a diet (OR: 1.119, 95% CI: 1.035, 1.208, p < 0.01 compared with no weight loss). This study identified NFFs as a part of the MD and MEDILIFE. NFFs linked to the MEDILIFE could help predict the outcome of a weight loss diet and appear to have a positive effect on PsyR, sleep quality, and maintaining a healthy weight. Thus, the consumption of NFFs grown and produced in the Mediterranean region could be a natural, healthy, and sustainable way of enhancing physical–mental health. Randomised controlled trials should be conducted to confirm the findings of this cross-sectional study.

ABSTRACT
The nutritional quality and biomass of various sprouts can be enhanced by Zn and red-blue light, especially the Brassica sprouts. However, the combined effects of this two on sprouts are rarely reported. In this study, different Zn concentrations (0, 1.74, 3.48, 10.43 and 17.39 mM) were combined with two ratios of red-blue light-emitting diodes (LEDs) (R: B = 1:2, 1R2B;R: B = 2:1, 2R1B, at 70 μmol m−2 s−1 PPFD, 14 h/10 h, light/dark) to investigate their mutual effects on the growth, mineral elements, and nutritional quality in flowering Chinese cabbage sprouts (FCCS). Fresh weight, dry weight, contents of organic Zn, soluble sugar, vitamin C, total flavonoids, total polyphenol, FRAP (ferric ion-reducing antioxidant power) and DPPH (radical inhibition percentage of 1,1-diphenyl-2-picrylhydrazyl) were significantly increased by Zn supplement (10.43 and 17.39 mM) and 2R1B, while hypocotyl length and moisture content were decreased remarkably by Zn supplement. Total glucosinolates contents in the sprouts increased dramatically under 2R1B compared with 1R2B, while photosynthetic pigments contents decreased. Heat map and principal component analysis showed that 2R1B + 17.39 mM Zn was the optimal treatment for the accumulation of biomass and health-promoting compound in FCCS, suggesting that a suitable combination of light quality and Zn supplement might be beneficial to zinc-biofortified FCCS production.
ABSTRACT
This bulletin discusses the effects of the COVID-19 pandemic on the production, distribution, and consumption of bananas, which are an important crop in the Brazilian agricultural sector. The temporary closure of commercial points and institutions has caused significant impacts on the banana production chain, which was already facing other challenges such as phytosanitary issues and water restrictions. The bulletin highlights the nutritional benefits of bananas and presents short and medium-term alternatives to mitigate the negative impacts of the pandemic on banana producers. It also emphasizes the need for actions to strengthen the entire banana chain considering the "new normal" that is expected to emerge.
ABSTRACT
An online questionnaire, consisting of 24 questions was applied to determine individuals' food purchasing, food hygiene, and nutritional behaviors during the COVID-19 pandemic. Of 658 re-spondents, 67% were female, 33% were male, 60% were 18-24 years old, and 25% were 25-31 years old. Supermarket shopping (73.9%) was the most preferred way to supply food, while the primary stocked up food was dried legumes (59.1%). The nutritional values and contents of foods were more paid attention to than before the COVID-19 pandemic, and the packaged foods (79.3%) were primarily preferred. The most preferred methods for cleaning fresh fruits and vegetables were washing under running water (59.7%) and soaking in water with vinegar (43.2%). The participants intended to eat healthy foods during the COVID-19 pandemic. However, the daily meal counts increased slightly. Food supplements, mainly vitamin C (73%) and vitamin D (40.5%) were consumed to strengthen the immune system. Additionally, social media (31.9%) and TV programs (20.3%) were very effective after medical doctor recommendations (32%) for orienting the nutritional behaviors of participants.
ABSTRACT
The aim was to investigate the use of bee products in Piaui state during the COVID-19 pandemic. To that end, data were collected remotely via an online form sent on WhatsApp and Instagram. Sampling was stratified considering the four mesoregions of Piaui and the sex of the participants using the Survey Monkey calculator. After stratification, the study contained 392 participants. A total of 85.46% of the interviewees reported regularly consuming bee products, primarily (24.78%) due to their nutritional potential. During the pandemic, 79.34% used bee products, honey being the most consumed (59.16%), followed by propolis honey (26.04%) and propolis alone (4.82%). With respect to COVID-19-related use, 23.47% and 3.21% of the subjects related consumption for disease prevention and treatment, respectively. In general, there was a 37.24% increase in the consumption of bee products during the pandemic, but most of the participants (52.05%) did not know the extent of the increase.
ABSTRACT
Due to the growing demand for instant food and lifestyle change after the COVID-19, aquatic pre-made products become popular. The unique nutritional and functional characteristics and processing suitability of aquatic products make them suitable for the development of ready-to-eat, instant heat, instant cooked and ready-to-use pre-made products. However, due to their unique fishy taste, texture and perishable characteristics, appropriate pretreatment technology, flavor and quality improvement and maintenance technology as well as storage technology in the processing and storage process need to be adopted so as to improve the quality of pre-made products. The main factors affecting the quality and safety of aquatic product pre-made products include biological hazards, chemical hazards and physical hazards. Therefore, quality control technologies of aquatic pre-made products including the raw material collection, processing process and the cold chain transportation process are necessary. In the future, aquatic pre-made products should be more nutritious, high-quality and diversified because of the improvement of nutrition and quality control technology.
ABSTRACT
Edible flowers belong to the culinary tradition of many cultures. Colors, shapes, flavors and aromas of flowers play crucial role for innovative and refined dishes, no longer considered a simple ornament of different recipes. New edible species have been selected in the INTERREG- ALCOTRA ANTEA. The scientific results show that edible flowers are rich in molecules beneficial for health (sugars, antioxidants, vitamins, minerals) especially if freshly consumed within few days of harvest.
ABSTRACT
Dairy production has a considerable effect on climate change due to emissions of greenhouse gases, but dairy products are meals that are well-known for their pleasant taste and nutritional value. During the Covid-19 outbreak, there were shortages of dairy goods on the shelves of grocery stores. This study investigated the consumption patterns of dairy products in Sabah. Using a pre-tested questionnaire, data were collected through online survey during Covid-19 outbreaks from 64 households comprising 16 from rural, 25 from town and 23 from city areas. The surveyed households were classified into 5 groups based on monthly household income: (i) ≤RM2000, (ii) RM2001-RM3000, (iii) RM3001-RM4000 and (iv) >RM4000. Among the participated households, 75% of respondents were female and 25% were male. There was a significant relationship among household income groups for fresh milk consumption. Regardless of areas and household incomes, the average monthly consumption for evaporated milk, fresh milk, condensed milk, powder milk, sweetmeats, yogurt, butter and ice cream per household were 1018g, 1425ml, 978g, 815g, 527g, 468g, 522g, and 650g, respectively. 28% of respondents monthly consumed 0.5-1.0 L fresh milk per household. 42%, 39%, 39%, 63%, 58%, 64% and 50% of respondents-- respectively-- monthly consumed evaporated milk, condensed milk, powder milk, sweetmeats, yogurt, butter and ice cream, where the amount of each component was not more than 500g per household. Results showed that 38% of respondents liked more on butter followed by cheese (30%), yogurt (20%), cream (9%) and condensed milk (3%). The 25% and 45% of respondents had reduced their consumption and expenditure behaviour, respectively. Results indicated that individual of city areas consumed more dairy products. Although cows add methane to our environment, organic dairy farming and husbandry methods can significantly reduce greenhouse gas emission.
ABSTRACT
Mushrooms have been an indispensable element of the human culture since antiquity and are cherished all over the globe for their nutritive and therapeutic benefits. Being acknowledged as “the new superfood” of the future, they are a cardinal component of human diet for boosting health status and well being. Mushrooms are endowed with antioxidant, antimicrobial, anticancer, prebiotic, antidiabetic, and anti-inflammatory activities, upholding a great therapeutic potential and a huge spectrum of clinical applications. The wide ranges of bioactive compounds including polysaccharides, polysaccharides protein complexes, peptides and proteins, terpenoids and phenolic compounds have been reported from diverse groups of mushroom. Laden with a wealth of nutrients and innumerable biomolecules of therapeutic worth, they are internationally appreciated and envisaged as world's largest untapped resources of dietary supplements. In the recent years, owing to significant healthier lifestyle changes, dietary practices of people and consumers opting for immunity enhancing supplements especially during the COVID-19 pandemic, the yearning for mushroom based nutraceuticals and functional foods is on rise. This review gives comprehensive details on the biodiversity of mushrooms, its nutritional and medicinal importance, secondary metabolites especially of nutraceuticals and pharmaceutical potential, and their role as bioactive agents and application in preparing mushroom based value-added products.
ABSTRACT
To clarify the most suitable fish paste for preparing lion's head meatballs, this study investigated the effect of adding 6 different silver carp fish pastes: fresh unwashed (group 1-1), fresh washed (group 1-2), frozen unwashed without antifreeze agent (group 2-1), frozen washed without antifreeze agent (group 2-2), frozen unwashed with antifreeze agent (group 3-1), and frozen washed with antifreeze agent (group 3-2) on the basic nutrients, color, texture properties, waterholding capacity, sensory and flavor properties, thiobarbituric acid reactive substance (TBARs) value, and total volatile basic nitrogen (TVB-N) content of pork/fish composite meatballs. The results showed that the contents of protein and fat in meatballs from groups 2-1 and 2-2 were lower than those in groups 3-1 and 3-2, and the contents of water, protein and fat were 61.68%, 11.32% and 19.41% for group 2-1, and 62.45%, 11.09% and 19.33% for group 2-2, respectively. The gel properties, hardness, elasticity, cohesion, and sensory quality of groups 3-1 and 3-2 were significantly higher than those of groups 2-1 and 2-2 (P < 0.05), but there was no significant difference compared with groups 1-1 and 1-2. The odor response value of groups 3 was lower than that of groups 1, and groups 3 had the highest sweetness value (3 039.66) and lowest bitterness value (534.59). The TBARs value and TVB-N content in groups 1-2, 2-2, and 3-2 (with washed fish paste) were significantly lower than those in groups 1-1, 2-1 and 3-1 (with unwashed fish paste) (P < 0.05). Since fresh fish paste is not easy to store and subject to spoilage, frozen washed fish paste with antifreeze agent can be used to produce composite meatballs.
ABSTRACT
Not only can agricultural science and research help bolster the nutritional value of staple crops, but it can also produce hardier varieties that can withstand pests and disease, meaning more produce surviving to harvest and providing additional income as a buffer. Since 2013, quality potato seed, improved crop management and value chain approaches have helped more than two million smallholder farmers in Africa and Asia. [...]making the right crops available for changing climates and cultural environments, and improving the availability of resilient, adapted varieties relies on protecting a back catalogue of genetic material to safeguard different features of different crops. The economic benefits of conservation are clear: gene banks like CIP’s contributed almost three-quarters of the $1 billion generated by the Victoria potato variety alone in Uganda between 1991 and 2016, which is just one indication of the potential economic value of conservation and utilisation of genetic materials.
ABSTRACT
The article provides functional properties' overview of vegetable raw materials – flax seeds. The studies' data on the determination of organoleptic parameters, the content and ratio of polyunsaturated fatty acids in samples enriched with flax seeds, linseed oil compared to the control sample are presented. Introduction of functional ingredients increased the nutritional value of convenience food. The positive effect of oil flax seeds on the organoleptic characteristics of the developed chopped convenience food was noted. Increasing the proportion of Omega-3 in convenience food and improving the ratio of Omega-3:Omega-6 in the developed convenience food has a positive effect on the protective functions of the body and the activity of the cardiovascular system during the pandemic of coronavirus infection (SARS-CoV-2).
ABSTRACT
Since the onset of the COVID-19 pandemic and the associated lockdowns, many events occurred, such as supply chain disruption, shielding and working from home restrictions along with diminished incomes and people's extra time spent in their own homes;all these have led to broad changes in consumer attitudes and behaviour. Therefore, people spent more time at home in all countries, and there was a significant increase in the number of people who enjoyed experiencing cooking at home, having a regular schedule for their meals. Pasta represents one of the most consumed food products in the world, their consumption increasing from year to year, experiencing a boost demand during the pandemic, because it has many important advantages such as: low cost, easy to cook, high nutritional value and long shelf life. Properly cooked pasta has a low potential to increase blood sugar, it slows down digestion and give a feeling of satiety for a longer period. The purpose of this study was to obtain information on consumer perceptions towards pasta consumption in order to develop new products that are adapted to current consumer requirements and preferences.
ABSTRACT
Andean grains are key elements in the construction of family production systems. These seeds speak of the history of a people, their customs and ancestral knowledge. The general objective of the work was to evaluate the food use, crop management and traditional knowledge about the medicinal use of ancestral Andean grains among the inhabitants of the districts of Quinua and Acos Vinchos (Ayacucho-Peru). Basic descriptive research, carried out by means of convenience sampling, the sample size determined by the Law of Diminishing Returns, after signing an informed consent form. Semi-structured individual interviews were applied to 96 informants. A total of 96.9% of the informants reported that they obtained quinoa grain from their own crops, and 24.0% obtained achita grain that they sowed directly on their land;no cañihua was cultivated. A total of 58.3% use quinoa and achita in their diet. The variability of the food use of ancestral grains, specifically quinoa and achita, constitute a natural source of vegetable protein of high nutritional value, which represents one of the main foods of the inhabitants of Quinua and Acos Vinchos. Traditional medicine derived from the ancestral knowledge of Andean grains is barely preserved, but this is not the case for other medicinal plants in the area, as this knowledge is still preserved.
ABSTRACT
Future trends in sustainable food consumption include the emergence of short food supply chains and growing interest in local food products. Among the drivers are the more urgent sustainability expectations, the emphasis on environmental and social responsibility, and the changing consumer needs, of which the desire for healthy and quality products, curiosity, uniqueness, and experience are the most prominent drivers. Today’s customers are becoming more aware and open to culinary discoveries and exotic delights. In this study, we investigated the importance of product attributes related to local products, and the motivational factors that determine purchase intentions. The significance of our work lies in the fact that we have studied young consumers’ intrinsic and extrinsic motivational factors. A quantitative consumer survey was conducted using a hybrid data collection method on a sample of 1756 respondents aged between 18 and 45 years. The questionnaire focused on product features, intrinsic and extrinsic motivational elements, and demographic characteristics. The results of our study provide strong evidence that the features associated with local products include but are not limited to the following: freshness, high quality, nutritional value, reliability, safety, evoking domestic flavours, naturalness, being healthy, environmentally friendly, etc. The motivational elements were grouped into four factors: hedonism, curiosity, nutritional value, and tradition. The main reasons for young respondents purchasing local food were taste and curiosity. Based on the results of the cluster analysis, we formed three groups having different features and different motivations for purchasing local products. Moreover, we had the opportunity to understand the attitudes and perceptions of young people towards buying local products. A key result of our study is that the “value-creators” segment considers local products to be healthy and nutritious.
ABSTRACT
Interest in the biological role of bioactive compounds present in plant by-products has increased over the last few years. This study aimed to investigate the nutritive value and biological activities of Egyptian Grape leaves (GL), Grape seeds (GS) and Mulberry leaves (ML), as well as investigate the impact of P-irradiation for improving the utilization of these plant by-products. The dose level 5.0 kGy showed highest the content of crude protein (24.42, 19.41 and 13.50 mg/100 g), as well as crude fiber (34.26 and 21.18 mg/100 g) for ML, GL and GS, respectively. Mulberry leaves has a highest content of protein and fiber at dose 5.0 kGy compared with GL and GS. The highest total phenolic content was found in GS (9.75 mg/g DW), followed by GL (7.32 mg/g DW) and the lowest in ML (5.97 mg/g DW). While ML had a higher total flavonoids content (5.61 mg/g DW) than GS (4.88 mg/g DW) and GL (2.86 mg/g DW). Total phenolic and flavonoid contents were significantly increased at 5.0 kGy. The highest level (83.25% and 80.24%) of scavenging activity (DPPH %) and inhibition activity of HCT 116 cells was recorded at 5.0 kGy by GS. All extracts irradiated at 5.0 kGy exhibited varying degrees of antibacterial activity against (Gram+ve and Gram-ve), the GS followed by GL then ML showed strong antibacterial activity with a diameter of inhibition zone of 26.2, 24.5 and 19.7 mm, against L. monocytoganes, respectively and 24.4, 21.4 and 17.2 against S. typhimurium, respectively. This study suggests that P-irradiation is an effective technique to enhance the recovery of phenolics and flavonoids from GL, GS and ML. Also in current study, antioxidant, antibacterial and anticancer activity has been suggested to appear a clear positive relationship with the total phenolic material. This study has proved that the Egyptian GL, GS and ML are rich sources of valuable phytochemicals and nutrients that can serve as a potential source of nutraceuticals and multifunctional food additives (antimicrobial, antioxidant, and anticancer). Phenolic compounds recovered from GL, GS and ML may have a potential role in fighting the COVID-19.
ABSTRACT
Food supply disruption and shortage verified during the current pandemic events are a scenario that many anticipate for the near future. The impact of climate changes on food production, the continuous decrease in arable land, and the exponential growth of the human population are important drivers for this problem. In this context, adding value to food waste is an obvious strategy to mitigate food shortages, but there is a long way to go in this field. Globally, it is estimated that one-third of all food produced is lost. This is certainly due to many different factors, but the lack of awareness of the consumer about the nutritional value of certain foods parts, namely peels and seeds, is certainly among them. In this review, we will unveil the nutritional and bioactive value of the waste discarded from the most important fresh fruit and vegetables consumed worldwide as a strategy to decrease food waste. This will span the characterization of the bioactive composition of selected waste from fruits and vegetables, particularly their seeds and peels, and their possible uses, whether in our diet or recycled to other ends.
ABSTRACT
The COVID-19 pandemic changed the life of many. The study aimed to identify fragile groups of the population regarding nutrition during the COVID-19 restriction period. An online survey was conducted from 26 July to 3 September 2020. A total of 1173 answers were received from persons aged 18–68 years living in Latvia. The results showed that food availability mainly was not limited, although for 15.3% responders restrictions caused increased worries about not having enough food, and 12.2% noted a decrease in the ability to eat preferred food. Responders aged 40–54 noted that they ate less, and that their food stocks were scarce in comparison with other age groups. Almost 50% of responders increased food consumption. One-fifth of responders increased consumption of foods of low nutritional value, especially among 25–39 year old persons and in households where the economic situation became worse. Fragile groups regarding nutrition in times of COVID-19 restrictions included households whose economic situation became worse during the COVID-19 restrictions, younger people who increased food consumption together with consumption of food of low nutritional value, and persons aged 40–54 years. The data from the study serve as an indicator that more detailed research is needed to determine whether crises such as the COVID-19 pandemic are changing dietary habits and food availability in the population.
