preparation example Construction

[0026] The preparation method of the above-mentioned astaxanthin-containing piglet feed additive may, for example, include the following steps: enzymatically hydrolyze the algae powder with a compound enzyme to obtain an enzymatic hydrolysis solution, and then dry it. Wherein, the composite enzyme includes cellulase and protease.

[0027] Specifically, mix the algae powder with deionized water at a material-to-liquid ratio of 1g: 3-5mL, adjust the pH of the mixture to the optimum pH of the compound enzyme, heat to 30-40°C, and then add the compound enzyme for enzymolysis .

[0028] As an option, the above-mentioned algae powder is preferably Haematococcus pluvialis powder, and the astaxanthin extracted from the algae powder has a better antioxidant effect.

[0029] Because the astaxanthin contained in the algae powder cells is difficult to be effectively absorbed by piglets, the embodiment of the present invention adds a compound enzyme during the preparation process to break...

Embodiment 1

[0046] Mix Haematococcus pluvialis powder with deionized water according to the ratio of material to liquid: 1g: 3mL, adjust the pH value of the mixture to 6, and heat to 40°C.

[0047] A compound enzyme containing cellulase and neutral protease at a weight ratio of 1:3 was added, the dosage of the compound enzyme was 3% of the weight of the algae powder, and the enzymolysis time was 6 hours at 40°C. In the process of enzymolysis, a compound small peptide chelating salt with a chelation rate of 70% is added. The amount of the compound small peptide chelating salt is 0.05% of the weight of the algae powder. The compound small peptide chelating salt contains small Peptide Chelated Zinc and Small Peptide Chelated Iron.

[0048] After enzymatic hydrolysis, the enzyme was inactivated at 90°C for 10 minutes to obtain an enzymatic hydrolysis solution.

[0049] The enzymolysis solution is concentrated to 30% of the mass of the original enzymolysis solution under the condition of 50° ...

Embodiment 2

[0052] Mix Haematococcus pluvialis powder with deionized water according to the material-to-liquid ratio of 1g:4mL, adjust the pH value of the mixture to 7, and heat to 35°C.

[0053] Add a compound enzyme containing cellulase and neutral protease at a weight ratio of 1:4, the amount of the compound enzyme is 2% of the weight of the algae powder, and the enzymolysis time is 7 hours at 35°C. In the enzymolysis process, a compound small peptide chelating salt with a chelation rate of 75% is added. The amount of the compound small peptide chelating salt is 0.03% of the weight of the algae powder. The compound small peptide chelating salt contains small Peptide Chelated Zinc and Small Peptide Chelated Iron.

[0054] After enzymatic hydrolysis, the enzyme was inactivated at 90°C for 15 minutes to obtain an enzymatic hydrolysis solution.

[0055] The enzymolysis solution is concentrated to 40% of the mass of the original enzymolysis solution under the condition of 50 DEG C, and vac...

Abstract

The invention relates to an astaxanthin-containing piglet feed additive as well as a preparation method and application thereof and belongs to the field of feed. The preparation method of the astaxanthin-containing piglet feed additive comprises the following steps: carrying out enzymolysis on algae powder with a compound enzyme, so that enzymatic hydrolysate is obtained, and then drying, whereinthe compound enzyme comprises cellulase and protease. The preparation method of the astaxanthin-containing piglet feed additive is simple in operation, can effectively release astaxanthin contained inthe algae powder and is beneficial to improvement of utilization rate of the astaxanthin. The piglet feed additive prepared by adopting the preparation method contains rich astaxanthin and proteins and can effectively improve appetite of piglets and skin color and hair quality of the piglets. The piglet feed additive provided by the invention can obviously improve daily feed intake and daily gainof the piglets and also can effectively improve the skin color and hair quality of the piglets when being used for preparing piglet feed.

Description

technical field [0001] The invention relates to the field of feed, and in particular to an astaxanthin-containing piglet feed additive and a preparation method and application thereof. Background technique [0002] Astaxanthin is a ketone carotenoid that widely exists in nature. It is known as "super vitamin E" and its antioxidant performance is hundreds of times that of vitamin E. At the same time, it has broad application prospects in anti-tumor, enhancing body immunity, food additives, feed additives, medical and health products, etc. Most of the astaxanthin currently on the market is chemically synthesized. The process of chemically synthesizing astaxanthin is complicated, and the structure is different from natural astaxanthin. It cannot be converted into the natural trans structure in animals, and the absorption efficiency is low. With the promotion of natural astaxanthin, people pay more and more attention to the efficacy of natural astaxanthin. [0003] Piglet feed...
