Đánh giá hiệu quả thuỷ phân cá nục gai (<i>Decapterus ruselli</i>) bằng enzyme alcalase trong sản xuất dịch đạm hoà tan giàu acid amin

Abstract

The research has been conducted on the hydrolysis process of Indian scad (Decapterus russelli) protein using Alcalase enzyme under natural pH conditions and a water/material ratio of 1/1. The results show that in order to achieve optimal efficiency, it is necessary to use an enzyme-substrate ratio of 93.48 AU/kg protein, to maintain a temperature of 60ºC for 6 hours. Following this process, the highest hydrolysis degree achieved was 73.01%, with a nitrogen recovery efficiency of 75.30% and a total volatile basic nitrogen of 0.8 g/l in the obtained hydrolysate solution. The final product contains 13.45 g/l of amino acid nitrogen and 0.59 mg/100 g of histamine, demonstrating a significant utilisation for diverse applications across various fields.
