Detanning of Deoiled Sal (<I>Shorea robust</I> A) Seed Meal with Sodium Carbonate Followed by Washing with Water

Abstract

Detanning of deoiled sal seed meal (DSSM) is studied with sodium carbonate solutions having concentretions of 0.01, 0.015 and 0.02 kg/1., as well as under different to cake ratios of about 34 to 70 1/kg about 78 to 90 percent in DSSM, can be extracted resulting in overall reduction of tannin content to below 4 per cent frorn original tannin content of 123 per cent.
