A kind of prozyme and application thereof
Technical field
The present invention relates to a kind of prozyme, is a kind of being used to produce the prozyme that gluten powder can improve the gluten powder yield and cut down the consumption of energy, and especially also relates to the application of this prozyme, belongs to the food fermentation technical field.
Background technology
Gluten powder is a kind of good flour-dough improver, is widely used in the production of bread, noodles, instant noodles, also can be used in the meat product as water-holding agent.At present domestic also gluten powder as a kind of gluten fortifier of green flour efficiently, use it for the production of high-toughness flour, tailored flour for bread, addition is unrestricted.Gluten powder still increases the effective ways of plant protein content in the food.Along with the requirement of Economic development and domestic food industrial development, in further expansion, demand also has further increase to the range of application of gluten powder.
There is big gap in gluten powder manufacturing enterprise aspect yield both at home and abroad, and domestic most of enterprises can isolate the gluten powder of better quality and larger amt in the wheat starch production process, and recovery rate is higher.Produce 200000 tons wheat starch production enterprise per year as France one family, produce gluten powder output up to more than 50,000 tons/year, its isolating gluten powder yield reaches more than 90%.And the aleuronat content of China is between 11-15%, and its isolating gluten powder yield only reaches 80%.This illustrates that we also have bigger room for promotion at the gluten powder yield.Zymin has extraordinary effect in raising gluten powder yield with aspect cutting down the consumption of energy.
Summary of the invention
At the deficiency that prior art exists, one of technical problem to be solved by this invention provides a kind of prozyme that can improve the gluten powder yield and cut down the consumption of energy; Two of technical problem to be solved provides the application method of described prozyme.
For solving the problems of the technologies described above, one of technical scheme that the present invention takes is: a kind of prozyme, and its one-tenth by following weight per-cent is grouped into: hemicellulase, 35-50%; Glutamine transaminage, 10-15%; Phytase, surplus.
Above-mentioned hemicellulase is made of following component in percentage by weight: beta-glucanase: 75%; Zytase, 25%.
Above-mentioned Transglutaminase EC2.3.2.13 is a trans-glutaminases.
Above-mentioned phytase is a plant hydrochlorate enzyme.
The application method of above-mentioned prozyme comprises following content: the prozyme of dry-matter raw material 0.1-0.2 ‰ mass ratio is added in the process water dissolve, add the dry-matter raw material then and carry out with face, wash one's face in process water, obtain gluten powder after pulverizing oven dry.
Prozyme of the present invention, beta-glucan and the xylan of its a large amount of hemicellulose enzyme component in can hydrolysis material destroys its long-chain and reticulated structure, discharges by the technology active substances such as protein of its complexing, wash out rate thereby improve gluten, improve raw material availability; In addition, hemicellulase has been removed viscous substances such as beta-glucan and xylan, helps the dough washing, can reduce power consumption, water saving.Glutamine transaminage composition in this prozyme, be a kind of can catalysis the epsilon-amino of Methionin cause the enzyme of polymerization of protein with γ-hydroxyl amide group formation covalent linkage of L-glutamic acid.Because the protein after the polymerization often shows than good functional property more before the polymerization, it is agglomerating that gluten is easy to, and improves the gluten yield.Phytase composition in this prozyme can destroy the chelate structure of phytate, discharges the protein that is chelated, and improves yield; After phytase decomposed the phytic acid macromole and is small molecules, dough viscosity reduced, can minimizing and face, the power consumption of washing one's face.
The present invention can improve the gluten powder yield and cut down the consumption of energy, and can shorten the production cycle, and is easy to washing, conserves water, and reduces dough viscosity, saves power consumption, reduces cost.
Embodiment
The present invention is described in more detail below in conjunction with embodiment.
The prozyme technological process of production of the present invention is: the mensuration enzyme was lived after each dhdps enzyme entered factory, and whether bacterial detection exceeds standard.Qualified after testing dhdps enzyme is transported to by following weight ratio according to enzyme activity and is respectively specified dog-house to enter the GMP workshop: hemicellulase, 35-50%; Glutamine transaminage, 10-15%; Phytase, 35-55%; Packed by setting specification by automatic packing machine behind each dhdps enzyme mixing, stochastic sampling detects qualified back packaging and warehousing again.
