Embodiment Construction

[0016] In order to make those skilled in the art more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with the examples.

[0017] The preparation method of a kind of yeast extract of the present invention, described preparation method comprises the following steps:

[0018] (a) Put yeast into the activation tank, and slowly add the activation solution to form a mixed solution. During the addition process, keep the temperature of the activation tank for constant temperature activation to obtain yeast milk;

[0019] (b) Add salt to the activated yeast milk, heat up to 50-60°C and perform autolysis at a constant temperature. Before autolysis, wash the yeast tank and infusion pipeline in this section with drinking water and perform steam disinfection;

[0020] (c) enzymatically hydrolyzing the autolyzed yeast milk to obtain enzymolyzed yeast milk;

[0021] (d) The yea...

Abstract

The invention discloses a preparation method of a yeast extract, which comprises the following steps: (a) adding yeast into an activation tank, slowly adding an activation solution to form a mixed solution, and carrying out constant-temperature activation while keeping the temperature of the activation tank to obtain yeast milk; (b) adding edible salt into the activated yeast milk, heating the yeast milk to 50-60 DEG C for constant-temperature autolysis, washing a yeast tank and a liquid conveying pipeline of the section with drinking water before autolysis, and carrying out steam disinfection; (c) carrying out enzymolysis on the autolyzed yeast milk to obtain enzymolysis yeast milk; (d) filtering and separating the enzymolysis yeast milk by using a yeast separator, and taking an enzymatichydrolysate supernatant for later use; and (e) carrying out vacuum concentration on the enzymatic hydrolysate supernatant with a triple-effect concentrator, discharging a small amount of enzymatic hydrolysate supernatant before discharging, and performing discharging to obtain the yeast extract when the moisture content of the concentrated solution is less than 60%.

Description

technical field [0001] The invention relates to the technical field of yeast extract production, in particular to a preparation method of yeast extract. Background technique [0002] The unique flavoring properties of yeast extract can also be used to season other foods. Adding it to products can also cover up the miscellaneous flavors of various foods themselves or produced by raw and auxiliary materials, play a role in alleviating sourness and increasing mellowness, thus greatly Improving the quality of products has been widely used in instant noodles, meat products, seasonings and other industries. Although the current yeast extract has been reported in the flavor research, the research on the characteristic meaty flavor is not in-depth. [0003] Although the yeast cell is rich in nutrients, it is surrounded by a thick cell wall. Yeast cell is a kind of eukaryote, its cell wall structure Yeast cell wall is mainly composed of glucan, mannan oligosaccharide, glycoprotein ...
