Problems solved by technology

However, since yeast extract powder is produced by hydrolysis of yeast through its own protease, and the reaction temperature is high and the hydrolysis time is long, the production efficiency of yeast extract powder is low, and the production cost is high, making the price of yeast extract powder high no less

Embodiment Construction

[0023] The yeast autolyzate of the present invention can be yeast autolyzate powder, yeast autolyzate paste or yeast autolyzate, the active ingredients of the three are substances obtained by yeast through enzymolysis or hydrolysis, yeast autolyzate powder, yeast autolyzate paste or yeast autolyzate The specific gravity of water in the yeast self-solution is different. Among them, the yeast self-dissolving powder contains little water and is in powder form. The moisture content of the yeast self-dissolving cream is below 12%, while the yeast self-dissolving solution is in a liquid state, that is, a solution with a high water content.

[0024] The first embodiment of yeast autolysate and the first embodiment of its preparation method:

[0025] see figure 1 , when preparing yeast autolysate, first obtain the yeast raw material, the yeast raw material can be molasses, baker's yeast, brewer's yeast, medicinal yeast, corn syrup, corn starch, etc. Of course, the yeast raw material c...

Abstract

The invention provides a yeast autolysate and a preparation method thereof. The autolysate is prepared by the following method: adding water to yeast raw materials to prepare a solution with a concentration of 5%-28%, and the yeast raw materials include molasses or baker's yeast or brewer's yeast Or at least one of medicinal yeast or corn syrup or corn starch, the solution is placed in an enzymatic hydrolysis tank, and heated to 50 ℃-70 ℃, the pH value is adjusted to between 4.5-7.0, and then the enzyme preparation is added, The weight of dry matter in the enzyme preparation is between 0.1% and 1.0%, until the dry basis weight ratio of amino acid nitrogen is detected to be greater than or equal to 1.5%. The present invention also provides a preparation method of the above yeast autolyzed powder, which is realized by using the above steps. The yeast autolyzed powder of the invention has low production cost and high production efficiency, and can be used as a substitute product of yeast extract powder.

Description

technical field [0001] The invention relates to a raw material of a food additive, in particular to a yeast autolysate and a preparation method of the yeast autolysate. Background technique [0002] Yeast is widely used in bread fermentation, beer fermentation and other fields, and there are many types of yeast, including baker's yeast, brewer's yeast, and medicinal yeast. Many existing food materials, such as molasses, cornstarch, corn syrup, and sugar beets, can be fermented to produce a large amount of yeast, and these food materials can be used as yeast materials. [0003] Yeast is rich in protein, amino acid and other substances. If the protein, amino acid and other substances can be obtained from yeast and used as food additives, it can effectively improve the taste of food, and it has a wide range of uses. [0004] Yeast protein or amino acids can be obtained by hydrolyzing yeast. Therefore, yeast extract powder can be obtained by hydrolyzing yeast, which can be used...
