Description
Technical field
The present invention relates to field of food, be specifically related to the preparation method of a kind of local flavor FSPC.
Background technology
The growing tension supplied along with domestic and international protein resource, agricultural industry practitioner is all finding new replacing energetically
Take in part vegetalitas high molecular weight protein for property raw material, especially young animal because of it and can cause intestinal inflammatory and intestinal tract injury,
The most eager to the demand of high-quality and safety protein sources.
Soybean, as the vegetable protein that resource is enriched the most in the world at present, has production scale big, relative safety
Height, the advantage such as relative low price, its purpose substitute: fish meal then has and yields poorly, and fluctuation is big, and price is high, and main
The shortcomings such as import to be depended on, but by soybean Peru Fish Dietary, in addition it is also necessary to albumen is concentrated further, soybean antigen is gone further
Removing, the step such as other ANFs removal further just can realize.FSPC traditional diamond-making technique has diluted acid to precipitate
Method, the ethanol wash precipitation method etc., it is many that traditional diamond-making technique has accessory substance, and processing technology is complicated, and antigen degradation the most thoroughly waits and lacks
Point.
The existing universal protein content of soybean protein series products is low, feed formula limited space, and is added by physical chemistry
Although the FSPC of work improves crude protein content, but palatability is poor, and production process brings a series of environmental issue, with
Time soybean antigen do not remove.At present, a kind of attractant is lacked strong, the preparation side of the local flavor FSPC that animal absorbability is good
Method.
Summary of the invention

Protein concentration principle:
Carbon source in material comprises yeast and may utilize carbon source and the most available carbon source of yeast, and table 1 is that yeast may utilize carbon
Source, table 2 predominantly yeast not may utilize carbon source, and the purpose adding enzyme is to utilize enzyme that these not may utilize carbon source to be converted into yeast
Available carbon source
In described dregs of beans, yeast available sugar composition is as shown in table 1:
Table 1
Title | Stachyose | Raffinose | Sucrose | Glucose | Fructose | Total amount |
Content/% | 3.92 | 1.94 | 8.78 | 0.76 | 0.09 | 15.49 |
In dregs of beans, yeast not may utilize SNSP composition as shown in table 2:
Table 2
Above NSP can be through multiple non-starch polysaccharide enzyme: arabinoxylanase, cellulase, mannase, half fiber
Element enzyme, pectase etc. is converted into monose, disaccharides or the oligosaccharide etc. that can be utilized by yeast.
Dregs of beans is during the fermentation first through saccharomyces cerevisiae (Saccharomyces cerevisiae CGMCC No.10336)
Aerobic respiration, converting carbohydrate is carbon dioxide and water, and in subsequent fermentations, between dregs of beans gap, oxygen is depleted, carbohydrate quilt
Yeast is converted into ethanol, carbon dioxide etc. through anaerobic respiration.
Yeast aerobic respiration reaction equation: C6H12O6→6CO2+12H2O+ energy
Yeast anaerobic respiration reaction equation: C6H12O6→2C2H5OH+2CO2+ energy (on a small quantity)
In dregs of beans, oligosaccharides and the SNSP after enzymolysis are through the aerobic respiration of yeast, anuerobic respiration, turn
Turn to volatile gas or water, by desiccation, it is achieved that the concentration of albumen.Concrete formula shows themselves in that
Finished product albumen=CP1/ (1-X-Y-Z),
In formula: CP1: the initial protein content of dregs of beans raw material
The skin of beancurd content that X: wind riddle removes
Y: through carbon dioxide, the water content of aerobic respiration release
Z: through ethanol, the content of carbon dioxide etc. of anaerobic respiration release
Achieve the concentration of albumen through above procedure, finished product protein content >=72%, simultaneously by the most available for animal swollen
The gas factor: raffinose, stachyose are removed;By the most available for animal SNSP (araboxylan, cellulose, sweet dew
Glycan, beta glucan) it is converted into the available monose of animal, disaccharides, compound sugar etc..The key technical indexes is as shown in table 3:
Table 3
Finished product index | Content |
Moisture | ≤ 5% |
Albumen | >=72% |
Cellulose | ≤ 0.4% |
SNSP | ≤ 3% |
Average protein molecular mass | ≤3000Da |
Flavor formation principle:
The acetic acid that culture propagation produces, lactic acid, propionic acid etc. can produce ethanol with yeast anaerobic stages, and a small amount of propyl alcohol etc. occurs
Esterification, forms bouquet principles matter such as ethyl acetate etc., and yeast itself can produce some flavor substances, such as: 1-OCOL,
Maltol.Sweat, along with the enzymolysis of protease, can form the delicate flavour materials such as sodium glutamate, fermentation ends after adding salt solution
Rear additional wall breaking enzyme is by substantial amounts of breaking yeast cellule membrane, and internal discharges in yeast cells in fresh material, the such as materials such as purine,
The residual sugar thoroughly not utilized after enzymolysis and protein combination, occur in dry run part Maillard reaction, formed in
Studies of The Aromatic Substances, along with enzymolysis in sweat, a large amount of protein are the little peptide of low molecule and delicious amino acid through flavor protease.Become
Product index is as shown in table 4,
Table 4
Finished product index | Content |
Nucleotides | >=0.28% |
Sodium glutamate | >=0.4% |
Free amino acid | >=2.5% |
1-OCOL | >=0.5% |
Maltol | >=0.2% |
Ethyl acetate | >=0.12% |
