Abstract

The invention provides a shrimp feed preparation method. The method includes: taking fruit peels as raw materials, smashing, adjusting the moisture content to range from 40% to 50%, processing for 10-25min under 100-150MPa, adding a leavening agent into the raw materials according to a proportion that a weight ratio of the raw materials to the leavening agent is 50-100:1, well mixing, fermenting for 1-2h at the temperature of 40-45 DEG C, and drying until the moisture content is lower than 10% to obtain shrimp feed. The leavening agent is composed of photosynthetic bacteria, bacillus, lactobacillus and saccharomyces by a weight ratio of 0.5-1:1-1.5:1-2:1.5-2. The shrimp feed preparation method is low in time consumption, and feed deterioration caused by bacterial contamination can be avoided.

Description

The preparation method of shrimp feed

Technical field

The present invention relates to a kind of preparation method of feed, be specifically related to the preparation method of a seed shrimp feed.

Background technology

Along with the development of agricultural, livestock and poultry breeding industry grows rapidly on the one hand, need a large amount of feed, and traditional feed formula is mainly based on grain, not only exist and strive the problem of grain with people, and along with the raising of provision price, the price of feed is also more and more higher, and then improve aquaculture cost, reduce cultivation profit.On the other hand, a large amount of pericarps is but abandoned in vain, not only causes waste but also pollutes environment.There is following problem in the method for current microbiological treatment pericarp: the microorganism 1) processing pericarp is all single culture, and the very difficult physics and chemistry shape thoroughly improving pericarp of single culture, air flue improves its palatability, improves the function of protein content.2) because miscellaneous bacteria in pericarp is more, traditional microbe leaven is difficult to become dominant microflora, usually by living contaminants, especially easily can be caused corrupt fungi pollution, cause feed spoilage.3) the fermentable time is longer, inefficiency.

Summary of the invention

The technical problem to be solved in the present invention is to provide the preparation method of a seed shrimp feed, and the method is consuming time short, and is not easy to be caused feed spoilage by living contaminants.

Technical scheme provided by the invention is the preparation method of a seed shrimp feed, take pericarp as raw material, pulverize, regulating moisture content to be 40 ~ 50%, under 100 ~ 150MPa, process 10 ~ 25min, is then that 50 ~ 100:1 ratio adds leavening in raw material in the weight ratio of raw material and leavening, mixing, at 40 ~ 45 DEG C of bottom fermentation then 1 ~ 2h, be dried to moisture content lower than 10%, obtain shrimp feed; Described leavening is photosynthetic bacteria, bacillus, Bacillus acidi lactici, saccharomycetic Mixed Microbes, and its weight ratio is 0.5 ~ 1:1 ~ 1.5:1 ~ 2:1.5 ~ 2.

Pre-press is carried out to pericarp, effectively can kill the miscellaneous bacteria in agricultural stalk, cell membrane, the cell membrane of agricultural byproduct can also be destroyed simultaneously, promote the organic Fast Stripping of the large molecule such as intracellular protein, fat, starch, cellulose, and be cracked into small-molecule substance.In addition, 100 ~ 150MPa HIGH PRESSURE TREATMENT only destroys non-covalent bond, to the vitamin of non-covalent bond, pigment, odourant molecules then without destruction, therefore well can retain local flavor and the nutritional labeling of pericarp.

Leavening of the present invention can produce the multiple enzymes such as protease, lipase, amylase, chitinase, the protein in pericarp, fat, cellulose, starch etc. can be degraded to micromolecular polypeptide and oligosaccharides.Because the HIGH PRESSURE TREATMENT in early stage is by organic for large molecule stripping smoothly, and the macromolecular substances of part long-chain is broken into small-molecule substance, therefore, a large amount of existence of these Small molecular nutriments promote microorganism Fast-propagation and are translated into Small molecular mycoprotein and oligosaccharides, effectively shorten fermentation time.

Photosynthetic bacteria, when utilizing pericarp, can release a large amount of heats, improves fermentation temperature, thus quick active bacillus, Bacillus acidi lactici and saccharomycete, promote its growth and breeding, shorten fermentation time further.

As preferably, photosynthetic bacteria, bacillus, Bacillus acidi lactici, saccharomycetic weight ratio are 0.8:1.2:1.5:1.8.When adopting this ratio, fermentation time can be down to minimum.

Compared with prior art, the present invention has following beneficial effect:

1) the present invention effectively can kill the miscellaneous bacteria in pericarp by pre-press, avoids polluting leavening, thus avoids feed spoilage.

2) pre-press can destroy cell membrane and the cytoplasm of pericarp, promotes the stripping of nutritional labeling and large molecular nutrition composition is cracked into Small molecular nutritional labeling, is convenient to follow-up Microbe synthesis and utilizes, promote microbial reproduction, shorten fermentation time.

3) photosynthetic bacteria releases a certain amount of heat when degrading pericarp, improves fermentation temperature, promotes bacillus, Bacillus acidi lactici and saccharomycete, promotes its growth and breeding, shorten fermentation time further.

4) if feed of the present invention can not be ingested by shrimps after dropping into pond, the microorganism (photosynthetic bacteria, bacillus, Bacillus acidi lactici and saccharomycete) be adsorbed in feed can continue breeding in pond, feed is effectively decomposed, to reduce the pollution to cultivation water environment.

5) in pericarp, distinctive fragrance can also produce certain phagostimulating effect to shrimps.

6) crude protein content of pericarp is generally lower than 10%, and after fodder, crude protein content significantly increases, and increasing degree is 140 ~ 150%.
