Sustainable microalgal biomass as a potential functional food and its applications in food industry: a comprehensive review.

Microalgae (MA) are the most abundant seaweeds with high nutritional properties. They are accepted as potential biocatalysts for the bioremediation of wastewater. They are widely used in food, feed, and biofuel industries and can potentially be food for future generations. MA-based purification of wastewater technology could be a universal alternative solution for the recovery of resources from wastewater for low-cost biomass feedstock for industry. They provide a wide range of functional components, viz. omega-3 fatty acids, along with a plenteous number of pigments such as ß-carotene, astaxanthin, lutein, phycocyanin, and chlorophyll, which are used extensively as food additives and nutraceuticals. Further, proteins, lipids, vitamins, and carbohydrates are described as nutritional characteristics in MA. They are investigated as single-cell protein, thickening/stabilizing agents, and pigment sources in the food industry. The review emphasizes the production and extraction of nutritional and functional components of algal biomass and the role of microalgal polysaccharides in digestion and nutritional absorption in the gastrointestinal tract. Further, the use of MA in the food industry was also investigated along with their potential therapeutic applications.

Taro starch: Isolation, morphology, modification and novel applications concern - A review.

Tuber and root crops are matured as fundamental food crops universally especially in tropical and subtropical regions. Among them, Taro (Colocasia esculenta) considered as 5th chief root crop due to its medicinal, ornamental and food formulation facets. Competitively it holds a considerable amount of starch even more than that to potato, sweet potato, cassava and so on. Taro corms starch (70-80%) contemplate as a cheapest abode for food industries due to its multifarious potentiality in food like stabilizer, emulsifier, fat substitute and as filler agent too. Baby foods, packaging material novelties, geriatric foods with resistant starch incorporation are the recently explored deliverables. Moreover, quality attributes of taro starch increases its behavioral versatility after modification competitively in a much better manner than native starch. This review aims to outline the current awareness about taro starch's molecular pattern, isolation procedures, properties, modifications and novel hit approaches for commercial viability. Gluten-free trait, hypoallergenic features and high digestibility are the additional benefits that widens its application scope to adapt better among pharma and textile in along with food sector.

Comparative nutritional and microbiological quality of ready to cook mixed vegetable curry.

Increasing urbanization, busy lifestyles has been providing a huge impetus to prefer ready to cook (RTC) food products. The research project was conducted to develop such a RTC product which fits the busy lifestyle of people as well as does not compromise on part of nutritional profile. The curry was prepared by washing, cutting, boiling (till vegetables gets soft) and blanching (5 min in 5% brine solution) followed by drying of five seasonal vegetables viz., carrot, peas, potato, cauliflower, beans in hot air dryer at 65 ± 5 °C for 10-12 h. A standardized gravy mix powder (onion, garlic, spices and herbs) was used to add flavor. Serving size for one person i.e. sachet contained 25 g dried vegetables, 10 g gravy mix powder and 200 ml water was prepared and packed. The recipe was finalized after sensory trials. The curry was ready in approximately 5 min in pressure cooker. The product remained well acceptable up to 4 months when packed in LDPE pouches under normal room temperature conditions. However, the shelf life of 4 months at 25 °C for a dried product is by all means considered good by the general expectations of dried foods and keeping the quality of dried foods reported in the literature.
