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.

Recent and historical developments in chelated fertilizers as plant nutritional sources, their usage efficiency, and application methods.

Chelates are nutrient-rich compounds that enhance the condition of plant tissues as micronutrients. Micronutrient deficiencies particularly iron (Fe) and zinc (Zn) leads to various problems for plant including chlorosis and necrosis etc. An adequate intake of Fe and Zn etc. is required by the human body. Biofortification of cereals with Fe and Zn is seen as a cost-effective solution to the problem of Fe and Zn deficiencies as well. In recent decades, many chelating compounds have been established and incorporated into agricultural systems. The most recent formulation involves the use of amino acids synthesized with one or more nutrient ions to improve fertilizer efficiency and better respond to environmental conservation. In addition to its primary function as a source of micronutrients, aminochelled are an active nitrogen (N) stimulant in plant nutrition, preventing the negative effects of basic N fertilizers like urea. The use of amino chelates, rather than just chemical fertilizers, has been shown to provide better production and quality as well as higher nutritional concentrations in several experiments. Furthermore, this review sheds light on various aspects of amino chelates fertilizers including types, history, and their effects on agricultural crops. In spite of amino chelates fast dominance in many countries' fertilizer countries, there is not enough scientific data and knowledge on the specific reactions of plants to biotic and abiotic stresses from amino fertilizers.

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.

Os quelatos são compostos ricos em nutrientes que melhoram a condição dos tecidos vegetais como micronutrientes. Deficiências de micronutrientes, particularmente ferro (Fe) e zinco (Zn), levam a vários problemas para as plantas, incluindo clorose e necrose, etc. A ingestão de uma quantidade adequada de Fe e Zn, etc., é exigida pelo corpo humano. A biofortificação de cereais com Fe e Zn também é vista como uma solução econômica para o problema das deficiências de Fe e Zn. Nas últimas décadas, muitos compostos quelantes foram estabelecidos e incorporados em sistemas agrícolas. A formulação mais recente envolve o uso de aminoácidos sintetizados com um ou mais íons nutrientes para melhorar a eficiência do fertilizante e responder melhor à conservação ambiental. Além de sua função primária como fonte de micronutrientes, os aminoquelados são um estimulante de nitrogênio (N) ativo na nutrição das plantas, evitando os efeitos negativos de fertilizantes nitrogenados básicos como a ureia. O uso de aminoquelatos, ao invés de apenas fertilizantes químicos, tem mostrado proporcionar melhor produção e qualidade, bem como maiores concentrações nutricionais em vários experimentos. Além disso, a presente revisão lança luz sobre vários aspectos dos fertilizantes aminoquelatos, incluindo tipos, história e seus efeitos nas culturas agrícolas. Apesar do domínio rápido dos aminoquelatos em muitos países de fertilizantes, não há dados científicos suficientes e conhecimento sobre as reações específicas das plantas aos estresses bióticos e abióticos dos fertilizantes amino.
