Optimization of Deodorization and Decolorization Process of Anchovy Fish Enzymatic Hydrolysate

Deodorization and decolorization of anchovy fish hydrolysate(AFH)was carried out by using macroporousresin as adsorbent material,and the results showed that DA201-C kind of macroporousresin was the best material. Furthermore,on the basis of single factor experiments,the smell,color and recovery rate were used as evaluation indexes to optimize the conditions of adsorption by orthogonal experiment L₉(3⁴),and the optimum conditions were pH6,content of macroporous resin 5%,time 1.5 h,and temperature 25℃.Under the optimum conditions,the score of sensory evaluation was 84.36.In addition,after deodorization and decolorization,taurine,alanine,methionine,and isoleucine in anchovy enzymatic hydrolysate decreased significantly(P<0.01),and the relative contents of aldehydes and nitrogen compounds in volatile components also decreased significantly.
