Embodiment 1

[0027] Embodiment 1, preparation edible fungus bacterium chaff feed

[0028] Both Lactobacillus plantarum and Pediococcus pentosacea were purchased from China Industrial Microorganism Culture Collection Management Center, the strain number of Lactobacillus plantarum was CICC 20764, and the strain number of Pediococcus pentosacea was CICC 22738.

[0029] The preparation method of Lactobacillus plantarum and Pediococcus pentosaceae seed solution is as follows: inoculate Lactobacillus plantarum or Pediococcus pentosaceae into the seed medium from the inclined plate (the composition of the seed medium is: peptone 10g / L, yeast extract 5g / L, Beef extract 10 g / L, glucose 20 g / L, sodium acetate 5 g / L, triammonium citrate 2 g / L, diammonium hydrogen phosphate 2 g / L, magnesium sulfate heptahydrate 0.58 g / L, manganese sulfate heptahydrate 0.19 g / L L, Tween 80 1mL / L, pH 6.0), cultured at 37°C for 12 hours, then transferred to fresh seed medium, and cultured at 37°C for 6 hours to obtain La...

Embodiment 2

[0040] Embodiment 2, preparation edible fungus bacterium chaff feed

[0041] Both Lactobacillus plantarum and Pediococcus pentosacea can be purchased commercially. The bacterial strains used in the present invention are all purchased from China Industrial Microorganism Culture Collection Management Center.

[0042] The preparation method of Lactobacillus plantarum and Pediococcus pentosaceae seed solution is as follows: inoculate Lactobacillus plantarum or Pediococcus pentosaceae into the seed medium from the inclined plate (the composition of the seed medium is: peptone 10g / L, yeast extract 5g / L, Beef extract 10 g / L, glucose 20 g / L, sodium acetate 5 g / L, triammonium citrate 2 g / L, diammonium hydrogen phosphate 2 g / L, magnesium sulfate heptahydrate 0.58 g / L, manganese sulfate heptahydrate 0.19 g / L L, Tween 80 1mL / L, pH 6.0), cultured at 37°C for 12 hours, then transferred to fresh seed medium, and cultured at 37°C for 6 hours to obtain Lactobacillus plantarum or pentose Pedio...

Embodiment example 3

[0053] Implementation case 3. Detection of nutritional components of edible fungus chaff feed

[0054] The DNS method was used to measure the reducing sugar content, the phenol-sulfuric acid method was used to measure the total sugar content, the Lowry method was used to determine the protein content, and the amino acid analyzer was used to determine the free amino acid content.

[0055] Detecting result shows that the nutritional labeling of edible fungi chaff feed of the present invention comprises:

[0056] Total soluble sugars 30% (mass percentage) or more; total soluble sugars refer to soluble mycofuran and monosaccharides, specifically including macromolecular polysaccharides, glucose, etc.;

[0057] Soluble polysaccharides 20% or more; soluble polysaccharides refer to soluble mycofuran, specifically including α-glucan and mannose, galactose, glucose, arabinose and glucose, galactose, fucose, arabinose, etc. heteropolysaccharides, etc.;

[0058] The total protein is 11...

Abstract

The invention discloses edible mushroom residue feed and a preparation method thereof. The edible mushroom residue feed preparation method comprises the following steps: degrading active ingredients of mushroom residue through a complex enzyme and fermenting a mushroom residue enzymolysis product through food-grade microorganisms, further degrading the active ingredients of the mushroom residue and releasing a functional secondary metabolite, and drying or spray-drying a fermentation product to obtain the edible mushroom residue feed which is intense in edible mushroom-featured flavor and easy in nutrient absorption, and has an antioxidant activity and an antibacterial activity. According to the preparation process disclosed by the invention, active ingredients in the mushroom residue raw material are degraded into polysaccharide, oligosaccharide, protein peptide and the like stronger in specific functional characteristics by the complex enzyme through a green biotechnology, and microorganism mixed fermentation is carried out to further generate beneficial secondary metabolite so as to improve antioxidant activity and antibacterial activity of the fermented product, thus improving the additional value of the product. The preparation process disclosed by the invention, breaking through a conventional mushroom residue feed processing technology, overcomes the shortcomings of the mushroom residue feed processing technology (direct material mixing or conventional simple fermentation), such as low mushroom residue utilization rate, low utilization rate of nutritive value and poor functionality, by organically combining biological enzymolysis and biological fermentation, and the economic value of the edible mushroom residue in the field of animal feed is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of mushroom chaff feed development, and more specifically relates to a preparation process of edible fungus chaff feed. Background technique [0002] my country is a big country in the production of edible fungi, and the output of edible fungi accounts for more than 75% of the world's total. After mushroom cultivation and harvesting, a large amount of edible fungus chaff will be produced. If discarded directly, it will cause serious environmental pollution. The main components of edible fungus chaff are mycelium residues and cellulose, hemicellulose and lignin decomposed by edible fungi, which are also rich in polysaccharides, amino acids and trace elements such as iron, calcium, zinc, magnesium and other metabolite. Has been used in fertilizer and feed development. However, due to the high crude fiber content of fungus chaff, its direct feeding performance is poor, which seriously restricts the digestion...
