Problems solved by technology

[0002] Fish sauce is one of the traditional condiments in my country. The processing and production cycle of traditional fish sauce takes 2-3 years. In order to shorten the processing and production cycle of fish sauce, technical means such as adding koji, heating and fermenting, and enzymatic hydrolysis are often used. However, This tends to reduce the quality of the fish sauce

Abstract

The invention discloses a complex enzyme preparation. The active ingredients of the complex enzyme preparation comprise protease, Halomonas urumqiensis and actinomucor elegans. The complex enzyme preparation is applied to fish sauce processing, produced fish sauce has pleasant mushroom fragrance, and the fishy smell is remarkably reduced. The Halomonas urumqiensis and the actinomucor elegans are combined for use, have the effects of reducing the content of heptanal metabolites and increasing 1-octen-3-ol metabolites and achieve synergistic interaction.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a compound enzyme preparation and its application in fish sauce processing. Background technique [0002] Fish sauce is one of the traditional condiments in my country. The processing and production cycle of traditional fish sauce takes 2-3 years. In order to shorten the processing and production cycle of fish sauce, technical means such as adding koji, heating and fermenting, and enzymatic hydrolysis are often used. However, This tends to reduce the quality of the fish sauce. The quality of fish sauce depends on the content and type of volatile flavor substances. Traditional fish sauce has many types of volatile flavor substances and has a positive flavor. Fish sauce processed by modern technology has fewer types of flavor substances and less beneficial volatile substances. . [0003] Volatile flavor compounds in fish sauce include aldehydes, ketones, alcoho...
