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.
