Embodiment 1

[0048] 1. Preparation of solid-state fermentation medium:

[0049] Weigh 80 parts by weight of sunflower seed meal and 20 parts by weight of wheat bran, add water and stir evenly to obtain a solid-state fermentation medium, control the water content of the solid-state fermentation medium to be 40-60%, and the sunflower seed meal can be The shelled sunflower seed meal can also be shelled sunflower seed meal, and the effect of using the shelled sunflower seed meal will be better. What adopted in this embodiment is shelled sunflower seed meal, which is provided by Haixin Oil Press Factory of Mongolian Autonomous County, Fuxin City. The wheat bran is commercially available.

[0050] 2. Preparation of mixed strains:

[0051] 1. Preparation of Kluyveromyces marx seed solution:

[0052]① Preparation of Kluyveromyces marx slant strains:

[0053] Kluyveromyces was provided by Jiangsu Institute of Microbiology, and the slant medium was YPG glucose agar medium. Prepare K. marx slant...

Embodiment 2

[0078] In this example:

[0079] When preparing the solid-state fermentation medium, control the water content of the solid-state fermentation medium to be 50%.

[0080] When preparing the Kluyveromyces maxima seed liquid, the Kluyveromyces maximus used was provided by the Jiangsu Institute of Microbiology, and Kluyveromyces maxima is a lysine-accumulating mutant strain obtained through AEC mutagenesis.

[0081] The mixed strains were sprayed on the solid-state fermentation medium, and the anaerobic fermentation was sealed for 48 hours, and the temperature was controlled at 30°C. Carry out aerobic fermentation 48 hours then, control temperature is 30 ℃. All the other are with embodiment 1.

Abstract

The invention relates to a sunflower seed meal microbial protein feed. The sunflower seed meal microbial protein feed is prepared by the following steps: mixing sunflower seed meal and wheat bran in a weight part ratio of 80 to 20 and adding water to prepare a solid-state fermentation culture medium; inoculating 5 parts by weight of a mixed strain on the solid-state fermentation culture medium and mixing and fermenting at 20-32 DEG C; and after fermenting, drying and crushing a fermented product to obtain the feed. The sunflower seed meal microbial protein feed takes the sunflower seed meal with husks as a main raw material, so that the production cost is low. The sunflower seed meal microbial protein feed contains bacillus subtilis, kluyveromyces marxianus, lactobacillus plantarum and candida tropicalis, has no any chemical additive and has the mellow flavor of fermented natural plants; the crude protein content of the feed is 35.5% and a plurality of amino acids, vitamins and microelements are contained in the feed, so that the sunflower seed meal microbial protein feed is a high-quality and low-price nutritional microbial protein feed.

Description

technical field [0001] The invention relates to a microbial protein feed, in particular to a sunflower seed meal microbial protein feed and a preparation method thereof. Background technique [0002] Sunflower seeds are rich in high-quality protein and are an available source of vegetable protein. According to reports, the international output of sunflower seeds has reached about 32.1 million tons, second only to soybeans and rapeseeds, and has become one of the five major oil crops in the world. Sunflower oil is a high-quality oil. Sunflower meal is a by-product of oil extraction from sunflower seeds. It is rich in nutrients. The sunflower meal is flaky, gray-black in color and has a sunflower fragrance. The content of B group, niacin, thiamine and choline in sunflower seed meal is very high, and the content of trace elements calcium and phosphorus is also higher than that of ordinary cakes. Sunflower meal contains a small amount of phenolic compounds, mainly chlorogenic ...
