Problems solved by technology

However, on the one hand, there are few studies on the preparation of protein feed by Chinese herbal medicine at present; It can be fully extracted and absorbed. Although there is currently a preparation process in which Chinese herbal medicines are extracted with active ingredients (such as alcohol extraction) and then added to feed, Chinese herbal medicines will produce more dregs after the active ingredients are extracted, which will also cause resources. waste of

Embodiment 1

[0037] A method for preparing yeast hydrolyzate, comprising the following steps:

[0038] (1) pulverizing and mixing leech, Gynostemma pentaphyllum and Hippophae rhamnoides with a mass ratio of 0.6:1:2 to obtain a traditional Chinese medicine mixture;

[0039] (2) Mix according to the ratio of Chinese medicine mixture and soybean meal mass ratio 0.2:1, add 2 times the volume of water, then add Streptomyces BY1 (inoculum size is 12%) and yeast (inoculum size is 3%), at 31 ℃ Down fermentation 12h, obtains fermented liquid;

[0040] (3) The fermented liquid is centrifuged to obtain a concentrate whose dry matter is 180g / L, and is centrifugally washed with three times the volume of clear water, concentrated and made into concentrated milk whose dry matter is 180g / L;

[0041] (4) Raise the temperature of the concentrated milk to 53°C to adjust the pH to 4.5, add mixed enzyme preparations, and enzymatically hydrolyze for 11 hours, then raise the temperature of the concentrated milk...

Embodiment 2

[0046] The difference from Example 1 is that in step (3), twice the volume of clear water is used to centrifugally wash the obtained concentrate.

Embodiment 3

[0048] The difference from Example 1 is that in step (3), four times the volume of clear water is used to centrifugally wash the obtained concentrate.

Abstract

The invention discloses a yeast hydrolysate as well as a preparation method and application thereof, and belongs to the technical field of yeast hydrolysate production. The method specifically comprises the following steps: crushing leeches, gynostemma pentaphyllum and sea-buckthorn, mixing with soybean meal, adding streptomyces BY1 and yeast for fermentation, performing enzymolysis on concentrated milk obtained by fermentation by using a mixed enzyme preparation, performing enzyme deactivation, and performing spray drying to obtain yeast hydrolysate. The obtained yeast hydrolysate has extremely high content of crude protein, acid soluble protein and amino acid nitrogen, is used as an additive component of a high-protein feed, and can remarkably promote the growth of livestock and improve the immunity.

Description

technical field [0001] The invention relates to the technical field of yeast hydrolyzate production, in particular to a yeast hydrolyzate and its preparation method and application. Background technique [0002] With the development of the breeding industry, under the environment of large-scale and intensive farming, the use of antibiotics as feed additives is banned in the feed, and the health of young animals such as weaned piglets has become one of the most difficult problems for breeding enterprises. In order to solve this The problem is that the breeding environment must be improved, and more nutritious feed and additives must be used to ensure animal health, which greatly increases the cost of breeding. At the same time, with the shortage of protein feed raw materials, it has become an urgent problem to be solved in the breeding industry to find a kind of alternative protein feed raw materials. [0003] As the earliest and most widely used microorganism, yeast is rich...
