“…Además, los valores en circulación para los metabolitos lipídicos fueron significativamente más bajos que en los grupos de control en comparación con grupos similares de pollos de engorde de raza Ross 308, criados bajo un manejo análogo en la misma estación, y también alimentados con una dieta de soya (14). Esta diferencia puede estar relacionada a diferencias en la concentración de soya de factores anti-nutricionales, que pueden variar con el tipo (15), origen ( 16) o maduración de los cultivos (17), o en la absorción o metabolismo del colesterol, que puede ser asociado o a cambios en el ambiente intestinal o al contenido de isoflavonas y fibra en la harina. Aún, un aumento en isoflavonas sería asociado a un aumento de niveles lipídicos totales en la sangre, lo que no fue el caso en este experimento.…”

Blood biochemical parameters of broilers fed differently thermal processed soybean meal

Objective. A 42-days feeding trial was carried out to evaluate the influences of differently thermal processed soybean meal on the broilers blood biochemical parameters. Materials and methods. A total of 200 male birds of Ross strain were allocated into five different diets formulated using differently heat-treated soybean meals, with ten birds per treatment and per replicate. Diets contained: raw soybean (controls), autoclaved for a short (121°C, 20 min; Aut1 group) or medium length period (121°C, 30 min; Aut2 group) soybean meal, micro-waved soybean meal (46°C, 540 Watt, 7 min; McW group) and browned soybean meal (120°C, 20 min; Brn group). Results. Blood serum metabolites showed that all treated diets presented lower lipid metabolism makers and higher protein metabolism markers. Broilers showed increased final body weight when fed heat-treated meals compared with control. Results suggested that thermal treatments altered the lipid metabolism in broilers that might originate a decrease in abdominal fat deposition. Conclusions. Comparison of the results for all the treated groups showed the Aut2 treatment is the most suitable method for soybean thermal treatment processing; in contrast, the Aut1 treatment had the closest results to the control group.

“…31 Also in line with our findings, greater isoflavone concentration was measured in soybean grain when plants were grown in waterlogged conditions compared to under well-watered conditions. 32 Similarly, soybeans grown under irrigated conditions had higher seed concentrations of daidzein and genistein compared to soybeans grown under nonirrigated conditions. 33,34 Somewhat in line with our observations, in a recent study in Australia examining the effects of waterlogging on phytoestrogen concentrations in subterranean clover (T. subterraneum L.), Enkhbat et al 13 observed increases in formononetin, biochanin A, and genistein across many genotypes of the species following water inundation ranging from 28 to 35 days.…”

Some forage legumes synthesize phytoestrogens. We conducted a glasshouse study to investigate how water stress (drought and waterlogging) influences phytoestrogen accumulation in red clover and kura clover. Compared to the red clover control, the 20 day drought resulted in an over 100% increase in the phytoestrogens formononetin and biochanin A, which together accounted for 91−96% of the total phytoestrogens measured. Waterlogging resulted in elevated concentrations of daidzein, genistein, and prunetin but not formononetin or biochanin A. Concentrations of phytoestrogens in kura clover were low or undetectable, regardless of water stress treatment. Leaf water potential was the most explanatory single-predictor of the variation in concentrations of formononetin, biochanin A, and total phytoestrogens in red clover. These results suggest that drought-stressed red clover may have higher potential to lead to estrogenic effects in ruminant livestock and that kura clover is a promising alternative low-or no-phytoestrogen perennial forage legume.

“…O consumo da soja tem aumentado consideravelmente no mundo todo, resultado das suas propriedades funcionais e de seus benefícios, sendo altamente recomendável a sua inclusão, assim como também a de seus derivados, na dieta diária dos consumidores (JÚNIOR et al, 2006). No Brasil, o consumo de grãos de soja está fortemente associado à manutenção da boa saúde e à redução do risco de doenças crônicas, principalmente devido a isoflavonas, por possuírem propriedades biológicas benéficas (FANTE et al 2011). (2004) fizeram uma pesquisa sobre a atitude dos consumidores em relação à soja e seus derivados e concluíram que o consumo desses alimentos ainda é baixo, sendo que, dentre os produtos derivados de soja, as proteínas, o ES e o tofu foram reconhecidos pelos consumidores como mais conhecidos e consumidos.…”

É crescente a preocupação por parte da população em consumir alimentos saudáveis, e pesquisas recentes têm mostrado a importância desse novo segmento no mercado. Por outro lado, as indústrias têm desenvolvido novos produtos a partir de alternativas que podem ser consideradas como resíduos industriais, as quais, se usadas em substituição a outros ingredientes, proporcionam aos alimentos alto valor nutricional, com características desejáveis, além de gerar valor agregado. Na composição da soja, há importantes componentes, sendo que os de maior destaque são as proteínas, as isoflavonas, os fosfolipídios, os antioxidantes, as vitaminas e as fibras, os quais têm comprovada ação benéfica para a saúde huma-CAPÍTULO
