Description
Technical field
The invention belongs to modified starch field, be specifically related to a kind of oxidation glutinous rice starch and preparation method thereof and application.
Background technology
Owing to native starch kind is limited, and exist cold water insoluble, stick with paste poor heat stability, anti-shear performance low, easy dehydration after cooling, easily aging, film property is poor and lacks the shortcoming such as water-resistant capacity, being of limited application when widely used new technology, new equipment, new technique in modern industry simultaneously, the needs of growing modern crafts and equipment can not be met, accordingly, it would be desirable to starch is carried out degenerative treatments.Starch denaturalization is exactly the character adopting physics, chemical or biological means to change native starch, cut off, reset, aoxidize or introduce in starch molecule substituent group by molecule and can prepare the starch derivatives that character changes, i.e. modified starch, in order to increase its performance or to introduce new features, overcome defect during application, to adapt to the needs that modern industry produces.
Mechanical activation starch belongs to physically denatured starch, refer to starch in mechanical activation process due to the effect of the mechanical forces such as friction, collision, impact, shearing, its crystalline texture is damaged, degree of crystallinity reduce, be finally transformed into amorphous state by polycrystalline state.Under the effect of mechanical force, the crystalline texture of starch receives destruction, the double-spiral structure of the starch that dissociated, and is greatly promoted hydrone and the combination of starch molecule free radical.The granular of starch mainly carries out wet ball-milling with organic solvents such as ethanol for ball milling liquid, and the normal-temperature dissolution degree of starch will be made to reach more than 80% and higher reactivity, and milling time needs more than 50 hours.And the preparation method of mechanical activation starch is to use dry method, through the short period, the ball milling of starch is activated, so that it may make it have good cold-water solution performance and higher chemical reactivity, the chemical reaction process of starch can be strengthened from inside.
Oxytarch is by the hydroxyl in oxidizing starch molecule, converts it into carbonyl and carboxyl, destroys the glycosidic bond in partial starch molecule simultaneously, causes a certain amount of degraded of molecule.It is a kind of extremely important and industrially applies modified starch very widely.Oxytarch is compared with ative starch in nature, and Oxytarch has the advantages such as color is shallow, gelatinization point is low, good fluidity, reaction control are low and stability is high, transparency is high, filming performance is good, adhesive tension is strong.
Oxytarch can adopt dry or wet to be fabricated by.The external research to modified starch relatively early, China in modified starch further investigation with abroad there is also certain gap.External in recent years that the research of Oxytarch is main in the selection of oxidant and catalyst, to improve reaction efficiency and to reduce production cost.Synthesis Oxytarch can use the oxidant production such as sodium hypochlorite, potassium permanganate, potassium dichromate.The wet process technique adopting sodium hypochlorite to be oxidant in current commercial production is more, but this technique generation waste water is many, contaminated environment.Being oxidant according to hydrogen peroxide, hydrogen peroxide is finally decomposed to water, without influence on environment, is an ideal friendly process.
Oryza glutinosa, as one of the main food of south each province, is the important source material producing Chinese traditional food.Glutinous rice starch has been taken as food thickening agent for processing such as food such as ice cream, meat soup juice and Oyster sauce flavoring agent.Glutinous rice starch is a kind of full amylopectin, its degree of polymerization is more than 1,000,000, molecular weight is more than 200,000,000, for maximum in natural polymer, it is a kind of three-dimensional macromolecule, side chain lengths is 20～25 AGU about, fork position alpha-1, and the glucose unit quantity that 6 glycosidic bonds connect is about the 5% of glucose unit sum.Glutinous rice starch molecule, because the relation of a fork structure is not susceptible to retrogradation, makes retrogradation weaken.Due to the chemical constitution that glutinous rice starch is special, most representative, but it is less both at home and abroad it to be carried out the research of degeneration, therefore to improve its application performance, widens range of application, it is necessary to glutinous rice starch is modified research.
