The homeopathic product Homeopatila 100 ® in the diet of Nile tilapia reduces stress during production and improves the well-being of fish. The objective of this study was to develop nuggets of tilapia fed with Homeopatila 100 ® and to assess their quality. Physical, chemical, microbiological and sensory analyses were performed on three formulations with 25, 50 and 75% mechanically separated meat (MSM) for each of the treatments. The nuggets with 75% MSM revealed a higher pH (5.89 ± 0.02), the tissue was softer (1.29 N ± 0.04), and they had a higher lipid value (15.96% ± 0.05). With 50 and 75%, the color (L * ) was darker (60.76% ± 0.91 and 60.03% ± 0.78), and there were lower protein amounts (15.54% ± 0.31 and 13.55% ± 0.35). Nuggets had an acceptable value of lipid oxidation (0.672 ± 0.007 mg MDA/kg). The microbiological analyses demonstrated that the product met the requirements of legislation. Nuggets with 25 and 50% MSM were deemed acceptable. There was no difference (p > 0.05) between the control treatment group and the Homeopatila 100 ® group for the analysis undertaken. The results indicated that the use of Homeopatila 100 ® in the diet of the Nile tilapia did not change the physical, chemical, microbiological and sensorial quality characteristics of the nuggets, ensuring consumer acceptability.

Nile tilapia juveniles that received the HomeoAqua Mega-3(®) in their diets had a decrease in the TL rates, mainly for the SFAs, and the n-6/n-3 ratio, compared with the control group, without any changes in the animal performance during the experimental period.

The possibility of varying beer formulations is acquired by variations in beverage production and the usage of different ingredients such as wheat, rice, corn, rye, cassava, honey, fruits, and others. Consequently, this work aimed to develop artisanal beers adding rice flakes and soursop pulp as adjuncts. Four artisanal beer formulations were elaborated, evaluating the following parameters: °Brix, pH, density, alcohol content, total acidity, real extract, primitive extract, color and sensory acceptability. Results revealed that the samples were in accordance with the standards established by legislation. In the sensory analysis through the acceptance test, both pure malt beer and adjunct formulations exposed good acceptance in relation to the analyzed attributes. Regarding the beer formulations development, the results were satisfactory, ensuring quality artisanal beer varieties.

ResumoDuas dietas foram avaliadas, uma controle (T1), com adição de 40 mL de solução hidroalcoólica a cada kg de ração e outra (T2), com adição de 40 mL do produto Homeopático a cada kg de ração em tilápias do Nilo. Foram distribuídos 200 peixes em 10 aquários, totalizando 20 animais em cada aquário, onde permaneceram por 63 dias. Foi realizado o monitoramento dos parâmetros físicos e químicos da água, desempenho dos animais, determinação da composição centesimal e a composição de ácidos graxos em cabeças de tilápia do Nilo. Não houve diferença estatística significativa entre os tratamentos em relação aos parâmetros da água, desempenho, determinação de umidade, cinzas, proteína bruta, lipídios totais. As tilápias do Nilo que receberam o produto homeopático incorporado na ração apresentaram a razão AGPI/AGS superior ao do tratamento controle, apresentado diferença significativa. As cabeças das tilápias analisadas constituem uma excelente fonte de lipídios totais.Palavras-chave: Homeopatia, Aquicultura, Tilápia do Nilo, Desempenho, Ácidos graxos. AbstractTwo diets were evaluated, one control (T1), with the addition of 40 ml of hydroalcoholic solution to each kg of feed and other (T2) with 40 ml of the homeopathic product every kg of feed in Nile tilapia. 200 fish were distributed in 10 water tanks, totaling 20 animals in each of the boxes, where they remained for 63 days. During the experiment was carried out monitoring of the physical and chemical parameters of water, animal performance, determine the chemical composition and fatty acid composition in heads of Nile tilapia. there was no significant statistical difference between treatments in relation to physical and chemical water parameters, performance, moisture determination, ash, crude protein, total lipids. The Nile tilapia that received the homeopathic product incorporated in the feed showed the PUFA / SFA ratio higher than the control treatment presented significant difference. The heads of analyzed tilapia are an excellent source of total lipids.

Soybean and corn oils are among the most popular vegetable oils, and are ingredients which are widely used in cooking and in the food industry. These oils contain many unsaturated fatty acids such as oleic, linoleic and linolenic acids, which makes them easily oxidized by oxygen. Extensive efforts are being made to prevent or minimize vegetable oil oxidation through the development of antioxidants. Phenolic antioxidants which are present in some extracts can be used as food additives to prevent lipid oxidation. In this study chromatographic analyses (HPLC and GC) of the Pluchea quitoc hydroalcoholic extract were performed. The content of phenolic compounds by the Folin-Ciocalteau method and the antioxidant properties against radicals 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) were also evaluated. The effect of samples prepared with soybean and corn oils enriched with Pluchea quitoc hydroalcoholic extract was determined and compared with samples of these oils which were free of antioxidants and with samples containing the synthetic antioxidant BHT. The results showed potential for application of the extract. A high content of phenolic compounds (314 milligrams of gallic acid equivalents (GAE)/g of extract) and good IC50 values were detected for the inhibition of the radicals DPPH and ABTS (13.2 µg·mL-1 and 5.6 µg·mL-1). In the evaluation of the oxidative stability of the oils enriched with this extract, it was found that at 1% concentration it was possible to obtain values of induction period (IP) close to the samples with added BHT.

O objetivo deste estudo foi elaborar hambúrgueres ovovegetarianos com adição de castanhas de caju e de baru, que é um fruto típico do cerrado brasileiro, avaliar as composições físico-químicas e realizar a análise sensorial para determinar a viabilidade dos produtos. Foram elaboradas duas formulações com semente de girassol, água, ovos, trigo para quibe, fumaça liquida, condimentos, sal, diferindo-se apenas o tipo de castanha utilizada, a castanha de baru e caju. A análise sensorial foi realizada com 53 julgadores não treinados, que avaliaram atributos de cor, odor, sabor, textura e impressão global mediante escala hedônica estruturada de nove pontos. Foi aplicado também testes de intenção de compra, e uma ficha para avaliação de consumo do provador. As analises físico-químicas realizadas foram para determinar umidade, cinzas, proteínas, lipídeos, fibras. O teor teórico de carboidratos foi determinado por diferença. Os resultados obtidos foram submetidos ao teste t Student com nível de significância de 0,05. Através da analise estatísticas pode-se observar que só houve variância significativa para o parâmetro de cinzas, porém sensorialmente não houve diferença significativa. De acordo com o índice de aceitabilidade (IA), os resultados revelaram que para os dois hambúrgueres avaliados os índices foram superiores a 83% para todos os atributos, indicando que os produtos foram bem aceitos pelos julgadores. Conclui-se que a elaboração de hambúrgueres ovovegetarianos apresentou ótima aceitação sensorial e intenção de compra, servindo como opção para pessoas que desejam diminuir o consumo de carne vermelha, ou para consumidores que seguem esse estilo de vida.
