Preparation method of lemna minor protein feed

Abstract

The invention discloses a preparation method of a lemna minor protein feed. The preparation method comprises the following steps of (1) taking 80 parts by weight of lemna minor under the condition of45 DEG C, performing drying until the water content is 80%, and performing crushing to obtain a mixture 1; (2) adding 20 parts of corn flour to the mixture 1 in step (1) to obtain a mixture 2; (3) adding 1% of nutritive salt liquid to the mixture 2 in the step (2), wherein the nutritive salt liquid comprises 0.18% of ammonium sulfate, 0.36% of potassium dihydrogen phosphate, 0.27% of magnesium sulphate and 1000ml of water to obtain a mixture 3; (4) placing the mixture 3 in the step (3) under the condition of 121 DEG C for heating for 20min, and performing sterilization to obtain a culture medium; (5) performing inoculating in the mixture in the step C in the proportion of geotrichum candidum to candida utilis to beer microzyme culture medium bacteria being 2.9 to 2.5 to 2.5, and at the temperature of 30 DEG C, performing sealed culturing for 80 hours; and (6) performing permanent-temperature drying the mixture in the step D at 65 DEG C to obtain permanent weight, and performing grinding to obtain powder. According to the preparation method of lemna minor fermentation protein powder, provided by the invention, the economical efficiency can be increased, and the lemna minor sources can be used to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a method for preparing duckweed feed protein powder. Background technique [0002] The shortage of high-quality feed resources in my country has always restricted the long-term development of animal husbandry. Duckweed, as a cellulose-rich duckweed, is rich in minerals and cellulose, but due to its low protein content, the current utilization rate is low. Low, its palatability is relatively poor, in the prior art, lacks a kind of method that duckweed is converted into single-cell protein feed, can be converted into protein content higher, nutritious duckweed protein feed, improves its utilization rate. [0003] Therefore, those skilled in the art are devoting themselves to developing a method for preparing duckweed protein feed, and determining the optimal strain ratio so that duckweed can be converted into duckweed protein feed with higher protein content and rich nutrition.
