Effect of different concentrations of stem juice of Oxalis tuberosa Mol. and juice of the fruit of Gaultheria glomerata (Cav.) Sleumer on the antioxidant activity of the heat-treated functional beverage.

Functional beverages with added health benefits are popular among peoples and athletes because they help them recover faster from intense workouts and perform better overall. This research set out to determine how well heat-treated stem juice from Oxalis tuberosa Mol. "oca" and fruit juice from Gaultheria glomerata (Cav.) Sleumer "laqa-laqa" performed as an antioxidant in a functional drink. The "oca" stems and the "laqa-laqa" fruit were collected to obtain the juice. For this study, 30 semi-trained panellists used sensory evaluation to rate four treatments (Bo, B1, B2, and B3) with varying quantities of "oca" and "laqa-laqa" juice. The results concluded that the treatment B2, which included 300 ml of "oca" stem juice, 800 ml of "laqa-laqa" juice, 1000 ml of treated water, and 220 g of refined sugar, was given the highest score after a physicochemical evaluation of its colour, smell, taste, and overall appearance. Similarly, the results showed that the protein content increased by 1.38%, the fat content by 1.08%, the moisture percentage by 99.5%, the ash content by 1.82%, and the carbohydrate content by 6.22% after B2 treatment. Similarly, results revealed significant enhancement in antioxidant profiling such as total polyphenols: 1825 mg of gallic acid/100 g and antioxidant Activity: 89.56% µmol of trolox /100 g. In conclusion, due to its high energy content and antioxidant activity, it may be a viable nutritional option for athletes who engage in rigorous, frequent physical exertion.

Conditioning of desert sandy soil and investigation of the ameliorative effects of poultry manure and bentonite treatment rate on plant growth.

Soil is the base of any ecosystem since it conserves nutrients and water for plant roots including agriculture and plantations. In dry and semi-arid places across the world, including the UAE, sandy soils are common. Their fertility is extremely low, and production is hampered by a number of agronomic challenges. Soil conditioner sources like bentonite and chicken manure might be used to improve the poor sandy soil attributes and hence boost soil productivity. From November 2019 to March 2020, an experiment was conducted to investigate the growth rates of Bougainvillea following bentonite and chicken manure amendments to sandy soil taken from Lehbab, Dubai. Bougainvillea was evaluated for its plant height (cm), max length of primary branch (cm), the number of leaves per plant, number of secondary branches, shoot weight (g), root length (cm), root weight (g), root/shoot ratio, chlorophyll contents, and chlorophyll a* and b*. In this experiment, a complete randomized design (CRD) with five treatments was used (10 replications per treatment). According to the findings, bentonite and chicken manure additions considerably influence the productive properties of sandy soil, as indicated by Bougainvillea growth. Additionally, the research suggests that Bougainvillea may be efficiently planted with 10% bentonite and 15% chicken manure applied to sandy soil, resulting in the healthiest plants compared to other amendments.

Resumo As bebidas funcionais com benefícios adicionais à saúde são populares entre as pessoas e os atletas porque os ajudam a se recuperar mais rapidamente de exercícios intensos e a ter um desempenho geral melhor. Esta pesquisa teve como objetivo determinar o quão beneficamente o suco do caule tratado termicamente de Oxalis tuberosa Mol. "oca" e o suco de fruta de Gaultheria glomerata (Cav.) Sleumer "laqa-laqa" atuaram como antioxidante em bebida funcional. Os caules da "oca" e os frutos da "laqa-laqa" foram coletados para a obtenção do suco. Para este estudo, 30 provadores semitreinados usaram a avaliação sensorial para avaliar quatro tratamentos (B0, B1, B2 e B3) com quantidades variadas de suco de "oca" e "laqa-laqa". Os resultados indicaram que o tratamento B2, que incluía 300 mL de suco de caule de "oca", 800 mL de suco de "laqa-laqa", 1.000 mL de água tratada e 220 g de açúcar refinado, obteve a maior pontuação após avaliação físico-química e avaliação de cor, cheiro, sabor e aparência geral. Da mesma forma, os resultados mostraram que o teor de proteína aumentou em 1,38%, o teor de gordura, em 1,08%, o percentual de umidade, em 99,5%, o teor de cinzas, em 1,82%, e o teor de carboidratos, em 6,22%, após o tratamento B2. Da mesma forma, os resultados revelaram aumento significativo no perfil antioxidante, como polifenóis totais: 1.825 mg de ácido gálico/100 g e atividade antioxidante de 89,56% μmol de trolox /100 g. Em conclusão, devido ao seu alto teor energético e à atividade antioxidante, pode ser uma opção nutricional viável para atletas que praticam esforço físico rigoroso e frequente.

O solo é a base de qualquer ecossistema, incluindo agricultura e plantações, pois conserva nutrientes e água para as raízes das plantas. Em lugares secos e semiáridos em todo o mundo, incluindo os Emirados Árabes Unidos, os solos arenosos são comuns. Sua fertilidade é extremamente baixa e a produção é prejudicada por uma série de desafios agronômicos. Fontes de condicionador de solo, como bentonita e esterco de galinha, podem ser usadas para melhorar os atributos do solo arenoso pobre e, portanto, aumentar a produtividade do solo. De novembro de 2019 a março de 2020, foi realizado um experimento para investigar as taxas de crescimento de buganvílias após bentonita e esterco de galinha em solo arenoso retirado de Lehbab, Dubai. A buganvília foi avaliada quanto à altura da planta (cm), comprimento máximo do ramo primário (cm), número de folhas por planta, número de ramos secundários, peso da parte aérea (g), comprimento da raiz (cm), peso da raiz (g), razão raiz/parte aérea, teores de clorofila e clorofila a* e b*. Neste experimento foi utilizado o delineamento inteiramente casualizado (DIC) com cinco tratamentos (10 repetições por tratamento). De acordo com os resultados, as adições de bentonita e esterco de galinha influenciam consideravelmente as propriedades produtivas do solo arenoso, conforme indicado pelo crescimento de buganvílias. Além disso, a pesquisa sugere que a buganvília pode ser plantada com eficiência com 10% de bentonita e 15% de esterco de galinha aplicado em solo arenoso, resultando, assim, em plantas mais saudáveis em comparação com outras alterações.
