Embodiment 1

[0007] A method for enzymatically preparing feed additive fructooligosaccharides is characterized in that: using Aspergillus niger to obtain fructose transferase through cultivation, adding it to a 30% sucrose solution, adjusting the pH value to 5 in a fermenter, and then Carry out enzymatic reaction at 62°C for 8 hours, carry out nanofiltration treatment, use activated carbon to decolorize and filter, concentrate, sterilize and dry, and pack for storage.

Embodiment 2

[0009] A method for enzymatically preparing feed additive fructo-oligosaccharides is characterized in that: aspergillus niger is used to obtain fructosyltransferase through cultivation, which is added to a sucrose solution with a concentration of 50%, and the pH value is adjusted to 8 in a fermenter, and then Carry out enzymatic reaction at 70°C for 10 hours, perform nanofiltration treatment, use activated carbon to decolorize and filter, concentrate, sterilize and dry, and pack for storage.

Abstract

The invention relates to a feed additive, in particular to a method for preparing fructo-oligosaccharide serving as a feed additive with an enzyme method, belonging to the technical field of deep processing of farm products. Fructo-oligosaccharide is a nuisanceless and functional dual-purpose feed additive which can be used for stimulating the growth of bifidobacteria, suppressing the growth of diarrhea causing pathogenic bacteria, eliminating or reducing the possibilities of specific recognition and binding of pathogenic bacteria with intestinal wall cells of a host animal by being bound with specific glycosyl binding sites of enteric pathogenic bacteria, reducing the settling and reproduction of salmonella, colon bacillus and enterococcus in intestinal tracts, inducing the production of microbial polysaccharide carbohydrate hydrolase in alimentary tracts of animals and directly or indirectly stimulating in-vivo immunologic competence of animals positively, and the like. By applying the fructo-oligosaccharide to a feed additive, the feed conversion rate and the health levels of animal organisms can be increased remarkably, a part of conventional antibiotics for feeds are replaced, the residual quantity of antibiotics in livestock products is reduced, the quality of livestock products is improved, and the growing speed of animals is increased remarkably.

Description

technical field [0001] The invention relates to a feed additive, in particular to a method for preparing a feed additive fructooligosaccharide by enzymatic method, and belongs to the technical field of deep processing of agricultural products. Background technique [0002] At present, in livestock and poultry breeding, in order to prevent epidemic infection and reduce the mortality rate of livestock and poultry, most methods such as adding antibiotics to the feed are adopted. It affects the growth and development of livestock and poultry, and the quality of livestock and poultry does not meet the requirements of green food, and cannot meet the market's demand for the safety and deliciousness of livestock and poultry products. Contents of the invention [0003] The purpose of the present invention is to provide a method for enzymatically preparing feed additive fructo-oligosaccharides in order to overcome the shortcomings of the above-mentioned prior art. Fructose-oligosac...
