Proteinase inhibitors and oligosaccharides of redgram (Cajanus cajan)

Proteinase inhibitory activity of local varieties of redgram (Cajanus cajan L) was determined. Chymotrypsin inhibitory activity (CIA) was more pronoun ced than trypsin inhibitory activity (TIA), in all varieties tested. The pe rcent loss of raffinose, stachyose and verbascose after soaking of redgram in 1 % sodium bicarbonate was 44 %, 23 % and 13 % respectively. Soaking of redgram followed by cooking decreases raffinose by 68 %, stachyose 57 % and verbascose 60 % respectively. Roasting of redgram decreased raffinose by 6 9 %, stachyose 66 % and verbascose 58 % respectively.
