Proximate composition of soybean cultivars BRS 232, BRS 257 and BRS 258 grown in an organic system

Resumo

The objective of this work was to evaluate the proximate composition of soybeans cultivars BRS 232 (commodities), BRS 257 and BRS 258 (both special cultivars for human consumption), all produced in an organic system. The grains were milled in a fine powder, and chemical analysis (protein, fat, ash, carbohydrates and moisture) were carried out according to Institute Adolfo Lutz (2005) and the values expressed in dry basis. There was no significant difference (p> 0.05) between ash and protein content for the cultivars analyzed. The BRS 232 cultivar showed lower lipid content compared to other cultivars. The carbohydrate content of all cultivars analyzed showed statistical difference between them (p <0.05) with higher levels for BRS 232, followed by BRS 257 and BRS 258. The soybean cultivars BRS 232, BRS 257 and BRS 258 produced in the organic system showed high levels of proteins, characterizing these soybean cultivars as a good source of protein for human consumption. The special cultivars for human consumption BRS 257 and BRS 258 showed yet high lipid content, providing more energy, which can be an advantage for human consumption.
