Embodiment 1

[0017] Example 1 Mixed enzymatic hydrolysis of earthworm and plant leaf protein to prepare polypeptide and amino acid mixture;

[0018] Step 1: Take fresh and live earthworms without pollution and place them in loose, moist and non-polluted mountain red soil, and place a sufficient number of peeled water chestnuts, apples, pears and other fruits with moderate sugar and acid content on them to promote their excretion of soil and feces in the cavity and intestines , washed with sterile water for later use;

[0019] Step 2: Take 200 kg of plant leaf protein powder, pulverize it with a hammer mill, pass it through a 40-mesh sieve, mix it with 50 kg of cleaned fresh earthworms in step 1, add 200 kg of tap water, and place in a In the stainless steel reaction tank of the cooling reflux device and the temperature rise temperature control device, the reaction temperature is set at 60°C ± 2°C, and the reaction is kept for 36 hours, during which the pH of the reactant is adjusted with d...

Embodiment 2

[0023] Example 2 Earthworms and animal hair are mixed and enzymatically hydrolyzed to prepare a mixture of polypeptides and amino acids;

[0024] Step 1: Take fresh and live earthworms without pollution and place them in loose, moist and non-polluted mountain red soil, and place a sufficient number of peeled water chestnuts, apples, pears and other fruits with moderate sugar and acid content on them to promote their excretion of soil and feces in the cavity and intestines , washed with sterile water for later use;

[0025] Step 2: Take 100 kg of air-cleaned animal hair, pulverize it with a hammer mill, pass through a 20-mesh sieve, mix it with 100 kg of cleaned fresh earthworms in step 1, add 150 kg of tap water, and place In a FRP reaction tank equipped with a cooling reflux device and a temperature control device, set the reaction temperature at 49°C ± 2°C, and keep it warm for 72 hours. During this period, adjust the pH of the reactant with dilute hydrochloric acid and dilu...

Embodiment 3

[0029] Example 3 Earthworms and animal tissues were mixed and enzymatically hydrolyzed to prepare polypeptide and amino acid mixtures;

[0030] Step 1: Take fresh and live earthworms without pollution and place them in loose, moist and non-polluted mountain red soil, and place a sufficient number of peeled water chestnuts, apples, pears and other fruits with moderate sugar and acid content on them to promote their excretion of soil and feces in the cavity and intestines , washed with sterile water for later use;

[0031] Step 2: Manually sort the internal organs of slaughterhouse animals and remove intestinal feces. After cleaning, beat them with a meat grinder. Take 150 kg of slurry, mix it with 150 kg of cleaned fresh earthworms in step 1, add 100 kg of tap water, placed in a ceramic reaction tank equipped with a cooling reflux device and a temperature rise temperature control device, set the reaction temperature at 55°C ± 2°C, and kept the temperature for 78 hours, during w...

Abstract

The invention provides a method for preparing water-soluble nutrient substances through mixed enzymolysis of earthworms and biomass, and particularly relates to a method for carrying out enzymolysis on various animal and plant tissues or extracts thereof by taking the earthworms as an enzyme source of a multi-enzyme system. The raw materials are leftovers of animal and plant processing industry, catering wastes, slaughter industry wastes, food industry wastes, aquatic product processing industry wastes and grease industry wastes. The preparation method comprises the following steps: performing enzymolysis on protein, grease, starch, cellulose and hemicellulose in biomass including the earthworm by using a cheap and powerful earthworm multienzyme system to obtain polypeptide, amino acid, fatty acid, glycerol, reducing sugar, oligosaccharide and other water-soluble organic macromolecular oligomers or monomers thereof; the compound can be used as an additive for fertilizers, feeds, baits and foods or production raw materials thereof. The reaction conditions are normal temperature and normal pressure. The technology is a key technology for realizing efficient conversion and utilization of biomass.

Description

technical field [0001] The invention belongs to the technical field of high-value utilization of biomass resources, and in particular relates to a method for preparing water-soluble nutrients by enzymatically hydrolyzing earthworms and biomass. This technology is the key technology to realize the efficient conversion and utilization of biomass. Background technique [0002] Earthworms are tenacious annelids that have existed on the earth for tens of millions of years. In order to survive in harsh environments, earthworms must obtain proteins, fatty acids, and carbohydrates from various organic substances that are difficult to decompose. Therefore, a very powerful multi-enzyme system has evolved in the body of earthworms to decompose proteins, fats, starches, and wood fibers. At present, the existing technologies are limited to using earthworms to eat garbage to reduce solid waste, using earthworms' self-generated protease to realize autolysis of worms, or using their body f...
