Description
Technical field
The present invention relates to a kind of production method of modified starch, specifically, be a kind of production method of esterification modified starch, belong to starch technical field.
Background technology
Along with modified starch is functional more and more stronger, insider is more and more higher to its cognition degree, and the market potential of modified starch is increasing.Appropriate starch is added in meat product, water-retentivity and the structural state of goods can be improved, modified starch has carried out physics, enzyme and chemical process process to native starch, change the natural character of starch, increase it functional or introduce new characteristic, thus improve quality product in the application, modified starch significantly can improve retentiveness and the emulsifying property of meat gruel, and meat emulsion product can be made to have good structural state and mouthfeel, its action effect is better than potato ative starch.The cassava modified starch had high temperature, acidity, shearing force and freeze-stable is used in burger is produced, not only increase the quality of product, also be very suitable for novel process to produce, the elasticity of goods, toughness and being knotted property can also be strengthened, improve water conservation, Oil keeping etc.Modified starch can not only occur for food provides structure and the stationary phase of needs, meanwhile, also having some kinds to start provide the function of health care to the mankind and cause people to pay close attention to the appearance of a kind of batching and additive.Food fibre, also known as anti-digestible starches, is a kind of special converted starch.Due to not digested, the absorption of heat can be made to reduce, also can help digest, be added in varieties of food items and increase nourishing function, be applied in the meal meals of diabetic subject particularly desirable.As the modified starch of fat substitute, be a class dextrin, enzymolysis or acidolysis product, replace fat baking, in the food such as meat product, ice-creams, not only there is the texture of fat, the more important thing is the intake reducing body fat, make the dietary structure of the mankind more reasonable.Although the current popularization at home of this series products still has certain difficulty, along with the raising of people's health care consciousness, the health of food will more and more be taken seriously, and the development potentiality of this kind of modified starch is huge.
Composite phosphate is a kind of common dispersion agent, industrial for all fields of national economies such as water treatment, pottery, printing and dyeing, papermaking; The Sodium hexametaphosphate 99 of food grade is used as foodstuff additive, mainly utilizes its dissemination.Also be a kind of water-holding agent, the every field of foodstuff production is widely used in food, the improvement of Food Quality is played an important role, as the effect of the water-retentivity to meat product, gel-strength, yield rate, all has different action effects to grain and oil goods, sea-food etc. in addition.Phosphoric acid salt is the most widely used foodstuff additive in current countries in the world, the phosphoric acid salt totally 8 kinds that current China approved uses, comprise tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, trisodium phosphate, tertiary sodium phosphate, Sodium phosphate dibasic, SODIUM PHOSPHATE, MONOBASIC, sodium acid pyrophosphate, Sodium Acid Pyrophosphate, the variation that these materials can contribute to food kind is added in food, improve its color, shape, keep freshness and the quality of food, and meet the demand of machining process, be very important quality improver in food.Composite phosphate is exactly two or more the phosphatic general designation applied in food-processing.Also be a kind of buffer reagent simultaneously, play shock absorption in the solution, the wide fluctuations of pH can be avoided, keep the stability of system in the late into the night.
Summary of the invention
