Problems solved by technology

[0004] In the prior art, the fermentation of seaweed products usually uses kelp powder or kelp residue, which will not only lose most of the nutrients, but also prolong the fermentation time
In the notification number CN107865188A, kelp powder is used as raw material. Because it is rich in alginate, the viscosity of the material is too high, the air permeability is poor, and the local overheating during the fermentation process requires manual turning. At the same time, the fermentation time is as long as more than 20 days, and the labor cost and time-consuming
However, if the kelp dregs are used to ferment the feed, the soluble substances such as fucoidan, iodine, and mannitol in the kelp have been lost, and the nutrition is greatly reduced.

Embodiment 1

[0021] The preparation steps of a kind of kelp probiotic fermented feed are as follows:

[0022] 1) Break fresh kelp, add 3 times the mass of water, add 10% mass of alginate lyase, start stirring, control the stirring speed between 180r / min-220r / min, and control the temperature at 30-35°C , After 30min-60min, the viscosity of the feed liquid is significantly reduced. After continuing the enzymatic hydrolysis for 2~3h, the enzymatic hydrolysis is completed, and the enzymatic hydrolysis kelp liquid is obtained.

[0023] 2) Add fermentation auxiliary materials to the enzymatic kelp liquid obtained in step 1). 1 kg of enzymatic kelp liquid corresponds to 0.3 kg of soybean meal, 0.3 kg of bran, and 0.4 kg of corn bran. Adjust the water content of the system to 50%. Stir evenly with the fermentation auxiliary material to obtain the fermentation mixture.

[0024] 3) Autoclave the fermentation mixture at 121°C, add Bacillus subtilis, Bacillus licheniformis, yeast and lactic acid bact...

Embodiment 2

[0033] The preparation steps of a kind of kelp probiotic fermented feed are as follows:

[0034] 1) Crush fresh kelp, add 2 times the mass of water, add 8% mass of alginate lyase, start stirring, control the stirring speed between 180r / min-220r / min, and control the temperature at 30-35°C , After 30min-60min, the viscosity of the feed liquid is significantly reduced. After continuing the enzymatic hydrolysis for 2~3h, the enzymatic hydrolysis is completed, and the enzymatic hydrolysis kelp liquid is obtained.

[0035] 2) Add fermentation auxiliary materials to the enzymatic kelp liquid obtained in step 1). 1 kg of enzymatic kelp liquid corresponds to 0.25 kg of soybean meal, 0.4 kg of bran, and 0.35 kg of corn bran. Adjust the water content of the system to 40%. Stir evenly with the fermentation auxiliary material to obtain the fermentation mixture.

[0036] 3) Autoclave the fermentation mixture at 121°C, add Bacillus subtilis, Bacillus licheniformis, yeast and lactic acid bac...

[0045] The preparation steps of a kind of kelp probiotic fermented feed are as follows:

[0046] 1) Break fresh kelp, add 4 times the mass of water, add 12% mass of alginate lyase, start stirring, control the stirring speed between 180r / min-220r / min, and control the temperature at 30-35°C , After 30min-60min, the viscosity of the feed liquid is significantly reduced. After continuing the enzymatic hydrolysis for 2~3h, the enzymatic hydrolysis is completed, and the enzymatic hydrolysis kelp liquid is obtained.

[0047] 2) Add fermentation auxiliary materials to the enzymatic kelp liquid obtained in step 1). 1 kg of enzymatic kelp liquid corresponds to 0.4 kg of soybean meal, 0.25 kg of bran, and 0.35 kg of corn bran. Adjust the water content of the system to 45%. Stir evenly with the fermentation auxiliary material to obtain the fermentation mixture.

[0048] 3) Autoclave the fermentation mixture at 121°C, add Bacillus subtilis, Bacillus licheniformis, yeast and lactic acid ba...

Abstract

The invention belongs to the field of feeds, and aims at providing a kelp probiotic fermented feed and a preparation method thereof. According to the kelp probiotic fermented feed, kelp is subjected to pre-enzymolysis by using sodium alginate lyase, so that sodium alginate in the kelp becomes alginate oligosaccharide through enzymolysis, the viscosity of fermentation raw materials is reduced, thepermeability is improved, and the fermentation conditions are improved; after auxiliary materials are added in an obtained kelp enzymolysis solution, probiotics are inoculated, and solid-state fermentation is carried out for 3-4 days to prepare the kelp fermented feed rich in alginate monosaccharide and probiotics. The kelp probiotic fermented feed and the preparation method thereof have the advantages that the loss of nutrients such as minerals and mannitol in the drying and powdering process of the kelp can be avoided; before the kelp is fermented, pre-enzymolysis is carried out, hard-to-consume substances such as sodium alginate and crude fibers in the kelp are converted into small molecular sugar through enzymolysis, and the digestibility of animals is increased. Meanwhile, the viscosity of the fermentation raw materials is reduced, the gas permeability of the fermentation raw materials is improved, common local overheating in solid-state fermentation is prevented, and the preparation method is more suitable for the growth of thalli.

Description

technical field [0001] The invention belongs to the field of feed, and relates to a kelp probiotic fermented feed and a preparation method thereof. [0002] technical background [0003] my country is the country with the largest scale of artificial breeding in the world. Kelp is rich in various amino acids, vitamins, minerals, trace elements, and many unknown growth factors. It is a food with high nutritional value. Studies have found that kelp also has various biological functions such as lowering blood fat, lowering blood sugar, regulating immunity, anticoagulation, anti-tumor, lead detoxification and anti-oxidation. The large-scale cultivation of kelp in my country provides strong support for the development and utilization of kelp. Using kelp to ferment feed can not only solve the problem of overproduction of kelp, but also broaden the range of raw materials for feed. Due to the reduction of soybean meal reserves in the global market, the development of the industry ne...
