Embodiment 1

[0029] The preparation method of the present embodiment comprises the following process steps:

[0030] A, raw material pretreatment: drying the waste slag of Grifola frondosa in an oven at 80°C, passing through a 60-mesh sieve after crushing;

[0031] B. Enzymolysis: Put the pretreated Grifola frondosa waste residue in an enzymolysis reactor, add water to boil according to the volume-to-weight ratio of 1:20, and cool to no more than 37°C. Add 0.5% of the mass of helicase to the cooled feed solution, adjust the pH value to 5.5, stir at 37°C for enzymolysis, and the enzymolysis time is 48h;

[0032] C. Enzyme inactivation: Stop stirring after the enzymolysis reaction is over, rapidly heat up the enzymolysis solution in step B to boiling, keep it for no less than 20 minutes, and inactivate the helicase;

[0033] D. Drying: Concentrate the enzymatic hydrolysis solution in step C under reduced pressure, and dry the enzymatic hydrolysis solution concentrated under reduced pressure...

Embodiment 2

[0036] The difference between this embodiment and embodiment 1 is:

[0037] B. Enzymolysis: Place the pretreated Grifola frondosa waste slag in the enzymolysis reactor, add water to boil with a volume-to-weight ratio of 1:20, and cool to 40°C. 1.5% Helicase was added to the cooled feed solution to adjust the pH value to 7, and the enzymolysis was stirred at 40° C. for 72 hours.

[0038] All the other contents are the same as in Example 1.

Embodiment 3

[0040] The difference between this embodiment and embodiment 1 is:

[0041] B. Enzymolysis: Place the pretreated Grifola frondosa waste slag in an enzymolysis reactor, add water to boil with a volume-to-weight ratio of 1:15, and cool to 35°C. 1.0% Helicase was added to the cooled feed solution to adjust the pH value to 6, and the enzymolysis was stirred at 35° C. for 48 hours.

[0042] All the other contents are the same as in Example 1.

Abstract

The invention belongs to the utilization of Grifola frondosa waste residue, in particular to preparation and application of enzymatic hydrolysate of Grifola frondosa waste residue rich in soluble dietary fiber, including the steps: drying and crushing Grifola frondosa waste residue in industrial production, and then enzymatically hydrolyzing the above product by helicase, and concentrating and drying the enzymatic hydrolysate to obtain the enzymatic hydrolysate of Grifola frondosa waste residue rich in soluble dietary fiber. The present invention effectively solves the technical problem thatthe waste residue of Grifola frondosa is difficult to treat in the prior art, has the advantages that the enzymatic hydrolysis product of Grifola frondosa after the enzymatic hydrolysis treatment contains rich amino acids and soluble dietary fiber, has better lipid-lowering, weight-reducing and blood sugar-lowering effects, effectively improves the added value of Grifola frondosa products and thelike.

Description

technical field [0001] The invention belongs to the utilization of Grifola frondosa waste residue, in particular to the preparation and application of an enzymatic hydrolysis product of Grifola frondosa waste residue rich in soluble dietary fiber. Background technique [0002] Grifola frondosa (Grifolafrondosa) is a precious medicinal and edible fungus, which belongs to Basidiomycotina, Phyllomycetes, Phyllomycetes, Polyporaceae, Grifola frondosa, also known as Polyporus bayifolia, Chestnut mushroom, Cloud mushrooms, lotus mushrooms, etc. are widely distributed in Japan, North America, Russia, and my country's Hebei, Yunnan, Sichuan, Zhejiang, Fujian, and Changbai Mountains. The fruit body of Grifola frondosa is soft, crisp like magnolia, and tastes like shredded chicken. It has a delicious taste and unique fragrance. It is a high-end rare edible fungus, and it is also a very precious medicinal fungus. The cultivation of Grifola frondosa in my country originated in 1980, and...
