CHEMICAL-COMPOSITION AND CONTENT OF ANTINUTRITIONAL FACTORS IN POLISHCULTIVARS OF PEAS

The seeds of 15 Polish pea varieties contained from 221 to 281 g/kg cr ude protein with a mean of 240.2 +/- 3.5 g/kg dry matter (DM). The wei ght of 1000 pea seeds, depending on cultivar, ranged from 209.4 to 280 .4 g. No interactive effect between the seed mass and the crude protei n content was detected. The highest significant negative correlation b etween weight of seeds and dietary fiber content was r = -0.815(XX). T he content of dietary fiber ranged from 161.5 to 209.9 g/kg with a mea n of 187.9 +/- 3.8 g/kg. The mean gross energy of seeds was 18.1 +/- 0 .28 MJ/kg. Amino acid composition of all the cultivars was similar, wh ich was indicated by a similar index of essential amino acids (EAAI) o f about 69.7 +/- 0.25. Trypsin inhibitor content in seeds was from 2.8 3 to 7.32 TIU/mg and the content of phytates ranged from 6.32 to 13.36 mg/g DM. The mean content of polyphenols and flavanols in analysed pe a cultivars was 0.92 amd 0.46 mg/g, respectively. In the seeds of most cultivars little or no pyrimidine glucosides, i.e. vicine and convici ne, were found. The overall mean oligosaccharide content was 64.3 +/- 1.8 g/kg, of which alpha-galactosides were 46.8 +/- 2.0 g/kg. The anti nutritional factor content was not significantly correlated with prote in content. No statistical relationship was found between crude protei n and dietary fiber content. It was observed that pea cultivars with h igher trypsin inhibitor activity contained significantly less flavanol s (r = -0.607(X)) and alpha-galactosides (r = -0.617(X)). The varietie s with higher seed content of dietary fiber contained the highest amou nt of alpha-galactosides (r = 0.514(X)).
