Abstract:

The nutritive quality of soya bean grain depends on many nutritional and anti-nutritional factors, such as proteins, trypsin inhibitors, phytate, phenolics, sulfhydril groups of proteins, malondialdehide. The aim of this study was to investigate content of noted nutritive and anti-nutritive factors in seven ZP soya bean varieties: ZPS 015, Bosa, Nena, Lidija, Olga, Lana and Laura. Experimental data could point out different properties and usage of ZP soya bean varieties. Regardless of insignificant differences in content of proteins and phytate, special attention is given to Lana and Laura, varieties lacking in Kunitz-trypsin inhibitor. It is also important to emphasise high content of phenolics in Nena variety as well as high sulfhydril groups and glutathione level in Nena and Olga. These substances contribute to nutritive value of soya bean grain.
