Abstract
The invention provides a method capable of improving gel strength of curdlan. The method includes: compounding microbial polysaccharide curdlan and hydrogen bond binding force promoting agents or microbial polysaccharide curdlan and coagulant aids, dissolving the mixture in water, and performing gel on the obtained solution at the temperature of 45-95 DEG C for 8-12 minutes. The jelly strength of the curdlan is obviously improved, and the hydrogen bond promoting agents can enhance the hardness at the high temperature state and the brittleness at the low temperature state, and obviously improve transparency of the colloid. The coagulant aids can reduce the gel initial temperature of the curdlan and improve the hardness and brittleness of the colloid at the low temperature state. When the hydrogen bond promoting agents and the coagulant aids act synergistically, the strengthening effects of the various aspects of the curdlan are improved.
Description
Technical field
The present invention relates to the applied technical field of novel microorganism polysaccharide curdlan, relate in particular to a kind of method that increases the curdlan gel-strength.
Background technology
Curdlan (Curdlan) is by the Tokuya Harada professor of Osaka university and works together and when research can utilize the petrochemicals mikrobe, find; He is a kind of new microbial exocellular polysaccharide by some mutation generations of Alkaligenes (Alcaligenes sp.); Because it has the peculiar property that under heating condition, forms gel, so be known as hot gel again.Shandong Food Fermentative Industry Research and Design Inst. since 2003 just the development curdlan work; After having solved a series of industrialization technology difficult problems; Built up the manufacturing enterprise of domestic first suitability for industrialized production curdlan, quality product can compare favourably with external product at present.
When curdlan is heated to differing temps, can form the diverse gel of character.Its suspension-s can form gel at about 54～80 ℃ of TR internal heating postcooling; This gel is called low strength gel (Low set gel or low hardening gel); Its gel has reversibility to temperature, reheats gel and can become colloidal sol, and intensity is lower; Suspension-s just can directly be formed gel without cooling when heating more than 80 ℃; The gel that forms like this is called high-strength gel (High set gel or claim high hardening gel), and this gel has non-reversibility to temperature, and sturdy construction also has snappiness.
Curdlan basically all is used for food service industry at present, and it can significantly improve product quality as foodstuff additive, improves retentiveness, visco-elasticity, the stability of product, and thickening power is arranged, and makes the product mouthfeel better.But its colloid intensity when the condition of high temperature is lower, has limited it in the application that needs the continuous high temperature condition; And be widely used in non-food product related industries aspect for needs; The not only needed cost that produces a desired effect is unacceptable, and the drawback that the one-tenth glue starting temperature of its existence is high, gel-strength is starkly lower than the normal temperature attitude during condition of high temperature is seriously restricting widening of Application Areas.The present invention just is being based on these shortcomings that how to overcome curdlan a kind of solution is being provided; Realize the mutability of curdlan heat irreversible gel starting temperature and significantly improving of condition of high temperature gel-strength, thereby make curdlan have more flexibility for some application specific IC conditions.
Summary of the invention
The present invention proposes a kind of method that increases the curdlan gel-strength, solved in the prior art curdlan gel-strength lower temperature state under the condition of high temperature low and also its form the starting temperature problem of higher of high-strength gel.
Technical scheme of the present invention is achieved in that a kind of method that increases the curdlan gel-strength: microbial polysaccharide curdlan and hydrogen bonding power promotor or microbial polysaccharide curdlan and the composite back of coagulant aids is soluble in water, afterwards with gained solution at 45～95 ℃ of following gel 8～12min.
As optimized technical scheme; Said hydrogen bonding power promotor is a kind of in Repone K, potassiumphosphate, calcium chloride, the borax or any several kinds; The composite weight ratio of said microbial polysaccharide curdlan and said promotor is 20: 1～1: 1.5; Fragility when said hydrogen bonding power promotor can significantly strengthen hardness and the low-temperature condition of curdlan when high temperature, and can significantly improve the colloidal transparency.
As optimized technical scheme; Said coagulant aids is a kind of in an ammonium nitrate, ammonium chloride, urea, the Secondary ammonium phosphate or any several kinds; The composite weight ratio of said microbial polysaccharide curdlan and said coagulant aids is 2: 1～1: 12; Coagulant aids can reduce the gel initial temperature of curdlan and when low-temperature condition, improve the colloidal strength and toughness, and the strengthening effect of its each side all got a promotion when both acted synergistically.
Owing to adopted technical scheme of the present invention; A kind of method that increases the curdlan gel-strength: microbial polysaccharide curdlan and hydrogen bonding power promotor or microbial polysaccharide curdlan and the composite back of coagulant aids is soluble in water; Afterwards with gained solution at 45～95 ℃ of following gel 8～12min; The gel-strength of curdlan is obviously promoted, the fragility when hydrogen bond promotor can strengthen hardness and the low-temperature condition of curdlan when high temperature, and can significantly improve the colloidal transparency; Coagulant aids can reduce the gel initial temperature of curdlan and when low-temperature condition, improve colloidal hardness and toughness; The strengthening effect of its each side all got a promotion when both acted synergistically.
