Abstract

The invention provides a fungus chaff protein biological feed additive and a preparation method thereof. The preparation method is characterized by comprising the following steps: processing edible-medicinal fungi chaff by drying, crushing and sieving with a 200-300-mesh sieve; adding lime water to soak for 24 to 36 hours, wherein the weight ratio of fungus chaff powder to lime water is 1: (10-30), and the lime water is under a temperature of 40 to 45 DEG C and at pH of 9 to 10; regulating the pH of the soaking solution to be 4.6 to 5.8 through dilute sulphuric acid; then adding complex enzyme which is 2 to 4% in percentage by weight of fungus chaff powder; performing enzymolysis for 24 to 36 hours under a constant temperature of 40 to 45 DEG C; squeezing to obtain juice; centrifugally separating; filtering; concentrating to obtain concentrated liquid with a specific gravity of 1.25; then adding saccharomycetes which is 8 to 12% in percentage by weight of the concentrated liquid to ferment for 18 to 30 hours under the conditions that the temperature is 30 to 33 DEG C and the ventilatory capacity is 1: 0.6V/V/min; performing spray-drying; then adding 5% of candida utilis and 5% of lactic acid bacteria; mixing; granulating by the wet method to obtain granules of which the particle size ranges from 60 to 80 meshes; sieving; packaging to obtain the mushroom bran protein biological feed additive. According to the preparation method, novel method, process and technical route are provided for the development and utilization of the edible-medicinal fungi chaff; the feasibility of the beneficial application of the fungi chaff is provided; in addition, the fungus chaff protein biological feed additive is high in utilization rate, low in production cost and high in economic benefit.

Description

technical field [0001] The invention relates to the processing and utilization of edible and medicinal fungus chaff, in particular to a fungus chaff protein biological feed additive and a preparation method thereof. Background technique [0002] Edible and medicinal fungus chaff is made of wood chips, cottonseed hulls, corn cobs, wheat bran, rice husks, waste cotton, furfural residue, xylose residue, bagasse, sugar beet residue, distiller's grains, rapeseed cake and various crop straw powders Edible and medicinal fungi are used as the main raw material for the cultivation of edible and medicinal fungi. The leftovers of the culture medium after harvest are commonly known as edible and medicinal fungus cultivation waste, fungus residue or residue; Decompose the compound of crude fiber and other components whose structure has undergone qualitative change. [0003] The cultivation industry of edible and medicinal fungi in my country has developed rapidly and has a large scale. ...
