Abstract
|
|
|
|
Dried anchovy (Engraulis japonica) was ground and treated with 0.3N NaOH solution and then hydrolyzed with proteolytic enzymes. Extracts obtained by centrifugation of alkali-enzyme treated anchovy slurry was compared with water extract for the yields of soluble solid, protein and ashes and organoleptic characteristics. The data for the yields of the soluble solids, protein and ash showed that a 2-3 folds increase in those yields was resulted by combined alkali-enzyme treatments when it was compared to water only extract. The organoleptic evaluation on the alkali-enzyme treated anchovy extracts also showed a 2-3 folds in flavor strength of all descriptions in odor and taste and a significant improvement in total odor or taste acceptability.
