Example Embodiment

[0026] The preparation method of the above-mentioned astaxanthin-containing piglet feed additive may, for example, include the following steps: enzymatically hydrolyze algae powder with a complex enzyme to obtain an enzymatic hydrolysate, and then dry. Among them, complex enzymes include cellulase and protease.

[0027] Specifically, the algae powder is mixed with deionized water at a material-to-liquid ratio of 1g:3-5mL, the pH of the mixed solution is adjusted to the optimal pH value of the complex enzyme, and the mixture is heated to 30-40°C, and then the complex enzyme is added for enzymatic hydrolysis .

[0028] Optionally, the above-mentioned algae powder is preferably Haematococcus pluvialis powder, and the astaxanthin obtained by extraction of this algae powder has a better antioxidant effect.

[0029] As the astaxanthin contained in the algae flour cells is difficult to be effectively absorbed by the piglets, the embodiment of the present invention adds a complex enzyme dur...

Example Embodiment

[0045] Example 1

[0046] The Haematococcus pluvialis powder was mixed with deionized water at a material-to-liquid ratio of 1g:3mL, the pH of the mixed solution was adjusted to 6, and the mixture was heated to 40°C.

[0047] A composite enzyme containing cellulase and neutral protease in a weight ratio of 1:3 is added, the amount of the composite enzyme is 3% of the weight of the algae powder, and the enzymolysis time is 6 hours at 40°C. In the enzymatic hydrolysis process, a complex small peptide chelate salt with a chelating rate of 70% is added. The amount of the complex small peptide chelate salt is 0.05% by weight of the algae powder. The complex small peptide chelate salt contains a small amount of 1:3 by weight. Peptide chelate zinc and small peptide chelate iron.

[0048] After enzymolysis, inactivate the enzyme at 90°C for 10 min to obtain the enzymatic hydrolysate.

[0049] The enzymatic hydrolysate is concentrated to 30% of the original enzymatic hydrolysate quality under...

[0051] Example 2

[0052] The Haematococcus pluvialis powder was mixed with deionized water at a material-to-liquid ratio of 1g:4mL, the pH of the mixed solution was adjusted to 7, and the mixture was heated to 35°C.

[0053] A composite enzyme containing cellulase and neutral protease in a weight ratio of 1:4 is added, the amount of the composite enzyme is 2% of the weight of the algae powder, and the enzymatic hydrolysis time is 7 hours at 35°C. The compound small peptide chelate salt with a chelating rate of 75% is added during the enzymatic hydrolysis. The amount of the compound small peptide chelate salt is 0.03% by weight of the algae powder. The compound small peptide chelate salt contains a small amount of 1:2 by weight. Peptide chelate zinc and small peptide chelate iron.

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

[0055] The enzymatic hydrolysate is concentrated to 40% of the original enzymatic hydrolys...

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...
