“…However, urease activity values were consistent with those considered optimal for heat-processed soybean products (DpH below 0.20; Butolo 2002). Although it is easier and cheaper to test urease activity compared with the determination of TI content when evaluating the presence of protease inhibitors, that analysis is less accurate, and the results show that urease is more heat-sensitive than TI (Purushotham et al 2007;F elix et al 2010F elix et al , F elix, Rivera et al 2013.…”

“…Faecal pH was measured using a digital pHmeter (331; Politeste Instrumentos de Teste Ltda, São Paulo, SP, Brazil) in 3.0 g of fresh faeces diluted in 30 ml of distilled water. The ammonia content was determined according to F elix, Rivera et al (2013). A 3 g sample of faeces collected within 15 min of defaecation was incubated for 1 h in a 500-mL volumetric flask containing 100 mL distilled water, to which three drops of octyl alcohol (1-octanol) and 2 g of magnesium oxide were added.…”

“…The trypsin inhibitor (TI) is the most important of these factors, as it impairs protein digestion (Rackis 1972). However, soybean processing needs to be properly controlled, because both under-and overheating may reduce the utilisation of its nutrients by the animals (F elix, Rivera et al 2013).…”

“…Considering that extrusion is a process that involves heat treatment, the extrusion of toasted soybean products, which commonly occur in commercial dog foods, may result in over-heating these ingredients, thus compromising the availability of amino acids to animals (F elix, Rivera et al 2013). To date, the results of the few studies on the inactivation of protease inhibitors of RSB included in extruded dog foods are controversial (Purushotham et al 2007;F elix et al 2010;F elix, Rivera et al 2013), probably due to the low or high inclusion level of RSB in the diets.…”

The objective was to evaluate the coefficients of total tract apparent digestibility (CTTAD) and metabolisable energy (ME) of raw soybeans (RSB) in extruded diets for dogs by three methods (difference, regression and substitution). We also evaluated the urease and trypsin inhibitor (TI) activity, CTTAD, ME and faecal characteristics of adult dogs fed diets containing increasing RSB levels. Six dogs, distributed in a 6 Â 6 Latin square design, were fed extruded diets containing 0, 60, 120, 180, 240 or 300 g of RSB/kg. Urease and TI were reduced in all diets after extrusion (p < .01), but TI was not completely inactivated. The inclusion of RSB linearly reduced (p < .01) the digestibility of dry matter (DM), organic matter and crude protein (CP) and linearly increased (p < .05) the digestibility of fat and gross energy and the ME of diets. The CTTAD of DM, CP and fat, and ME of RSB, predicted by the substitution method were: 0.767, 0.758, 0.960 and 20.7 MJ/ kg, respectively. The dietary inclusion of RSB reduced faecal DM content and promoted a quadratic increase (p < .01) of pH and ammonia. Increasing RSB in diet reduced CTTAD estimate errors (p < .05). When 300 g of RSB were added per kg of diet, CTTAD of RSB estimated by the three methods did not differ (p>.05). The three methods can be used to determine RSB digestibility. Diet extrusion may not be able to completely deactivate the protease inhibitors present in the RSB. HIGHLIGHTS Extrusion may not be able to deactivate protease inhibitors of raw soybeans. Raw soybeans reduce nutrient digestibility of extruded diets in dogs. The substitution method is recommended to evaluate digestibility of raw soybeans.

“…Oligosaccharides, i.e. mainly galactooligosaccharides (stachyose and raffinose), on the other hand, limit soybean food products' nutritional value and reduce metabolisable energy that can be obtained from soybean meal since they are indigestible and cause irritation of the gastrointestinal tract in humans and animals (Félix et al, 2013;Gulewicz et al, 2014;Qiu et al, 2015). In consequence, the use of soybean seed as food and feed is limited, but the demand for 'food grade' soybean is on the rise due to the increasing awareness of the health benefits connected with soy food consumption.…”

Given the great potential of soybean (Glycine max (L.) Merr.) as a staple crop for food, feed and pharmaceutical industry, improving the genetic basis of seed quality is one of the main breeding aims on a global scale. An important quality trait is saccharide composition since it affects digestibility and nutritional value of soybean seed, affecting the usability of this agricultural commodity. This 3-year research (2010-2012) investigated soybean variability by measuring saccharide contents (glucose, fructose, sucrose, raffinose, stachyose) in high-yielding genotypes (maturity groups 00-II) suitable for almost all European regions, while taking into consideration the effect of weather conditions. Statistical analyses included calculating the basic measures of descriptive statistics, analysis of variance (ANOVA), determining correlation and using the Nearest Neighbour clustering to construct a dendrogram based on the Euclidean distance. Results showed the existence of diversity in saccharide content with the influence of genotype, year and their interaction being statistically significant. The lack of correlation between investigated parameters indicates the use of indirect selection is not possible. Nevertheless, the determined divergence indicates the given set of genotypes is suitable for use in future crossing programmes aiming to produce cultivars with more beneficial sugar content in comparison to the existing ones.

Appropriate germination can improve the nutritional value and bioactivity of soybeans; however, few studies have assessed the effect of germination on soybean proteins. This study examined the physicochemical property, antioxidation, and cytoprotective effect of the germinated soybean proteins (Gsp). Gsp was extracted from soybeans which germinated for 0–3 days using the method of alkali‐solution and acid‐isolation extraction. The results showed that germination could digest soybean proteins into the smaller molecules; enhance the degree of hydrolysis, emulsifiability, and foaming capacity; increase the removal rate of ABTS, DPPH, O2−˙, and ˙OH radical; and decrease the reducing power and lipid peroxidation of Gsp. Additionally, Gsp was able to protect HL‐7702 human hepatocyte cells against benzo(a)pyrene (BaP)‐induced cytotoxicity through mediating the cell cycle arrest, suppressing apoptosis, and increasing reactive oxygen species (ROS) levels. This work demonstrated that germination could enhance the physicochemical property and antioxidant activity of Gsp, which also displayed the remarkable cytoprotective effect. This study provided a fundamental basis for substantiating dietary of Gsp used for resistance to oxidation and hepatic injury.
