Estudos das características físicas e químicas durante o processamento da soja integral utilizada na alimentação de monogástricos / Physical and chemical characteristics studies during the processing of soybean used in monogastric feeding

Este estudo objetivou avaliar o processamento da soja integral, coletada após saída do reator a vácuo. Foram coletadas um total de 10 amostras do produto final, classificadas em 6 grupos: amostra grãos total, inteiros estragados, inteiros queimados, quebrados normais e grãos quebrados queimados. As análises foram realizadas baseadas nos controles de qualidade como: umidade, proteína bruta, proteína solúvel e urease. Verificou-se que a amostra de grãos inteiros normais apresentou valores de proteína bruta, proteína solúvel (Psol), umidade e urease semelhantes (P <0 ,05) à amostra total da soja desativada. No entanto, os resultados das análises bromatológicas encontrados para o grão inteiro normal foram, em sua maioria, diferentes (P < 0,05) daqueles encontrados para as demais amostras avaliadas. Os grãos quebrados queimados tiveram menor (P < 0,05) valor de umidade, proteína bruta, Psol, Urease em relação aqueles obtidos para o grão inteiro normal. Concluiu-se que as amostras de grãos inteiros normais e grãos quebrados normais constituem a maior parte (90%) da parcela total da soja integral, e que possuem valores de Psol e urease adequados para uso em rações de aves e suínos. As amostras restantes possuem pouco valor na qualidade da soja, devido a baixa participação na amostra total. Ainda, de acordo com os resultados obtidos, pode-se inferir que a moagem do grão de soja antes da desativação pode melhorar o processamento, obtendo valores de Psol e urease mais uniformes e maior rendimento aos digestores (capacidade/hora).

This study was aimed of evaluating the processing of full fat soybean, collected after the reactor exit vacuum. It was collected a total of 10 samples of the final product, classified into six groups: total sample grain; normal whole; spoiled whole; burnt whole; normal broken, and burnt broken. Analyses were performed based on the quality controls such as moisture; crude protein; soluble protein, and urease. It was verified that the sample of normal whole grains presented crude protein, soluble protein, humidity and urease values similar (P < 0.05) to the total sample of deactivated soybean. However, the bromatological analyses results found for normal whole grain were mostly different (P < 0.05) from those found for the other samples evaluated. Burnt broken grains presented lower (P < 0.05) values of humidity, crude protein, soluble protein and urease in relation to those obtained for normal whole grain. It can be concluded that normal whole grains and normal broken grains samples constitute the biggest part (90%) of the total sample of full fat soybean and have adequate soluble protein and urease values for the use in poultry and pig feeds. The remaining samples are not of great importance to soybean quality due to the low participation in the total sample. Also, according to the results obtained, it can be infered that grinding soybean grain before deactivation can improve processing and obtain more uniform soluble protein and urease values and higher yield to digestors (capacity/hour).

Nowadays, there is a great interest in the research and the production of functional foods, such as isoflavones. Which present proven action on the prevention of health problems, such as cancer and cardiovascular diseases. Considering the importance of soybean supplements standardization, this study aimed identifying and quantifying the isoflavones in products sold at different pharmacies. Isoflavones samples were acquired in six different pharmacies specialized in the production of phytotherapic medications. The isoflavones were extracted, quantified and identified in HPLC. None of the samples, from different pharmacies, presented the isoflavones content presented on the label, i.e., 20 mg. In relation to the isoflavones profile, the highest levels found were of daidzein, with up to 66.8 ± 0.09 µg, being the lowest levels the ones of genistein. It is necessary, therefore, the adoption of methods for the standardization and characterization of the raw materials used by different pharmacies. It would assure the isoflavones content, once they are essential for the effects prescribed by the professionals in the medical area.
