Estimation of lesser known anti-nutrients; Phytic acid and Trypsin inhibitor from the edible bamboo shoots and their processed products of Arunachal Pradesh, India

Abstract

Bamboo shoot is well known for the high nutritive values it possesses. People in Northeastern India, the majority of which are tribal and lives in rural area consume bamboo shoot extensively without knowing its benefits and demerits. The present study was undertaken in Arunachal Pradesh, India considering the possible threats it may pose to the people of the region in particular by estimating the anti-nutritional elements such as Phytic acid and Trypsin inhibitor from bamboo shoots of seven species and its three processed forms that are widely consume. Phytic acid content was observed within a range of 0.81 to 0.31 Pmg/100g and 0.75 to 0.38 Pmg/100g in bamboo shoots and processed products respectively whereas trypsin inhibitor in tender shoots of all the seven species (0.53-0.24 TIU mg/protein) and processed products (0.37-0.19 TIU mg/protein) was also recorded. Similarly, there were also significant variations in phytic acid (F=41.509, P<0.001) and trypsin inhibitor (F=16.631, P< 0.001) concentration between the fresh shoots and processed forms. The amount of antinutrients estimated from these samples are considerably less and far from any harm.
