Abstract
The invention discloses a method for preparing stable slow-digestion starch and belongs to the field of modified starch processing. The principle of the method is that: rice starch is degraded to form short chain straight chain starch based on high-power ultrasonic waves, and a single spiral V-shaped microcrystalline starch-lipid complex is formed through high-temperature lipid reaction and short-term crystallization, and has obvious slow-digestion characteristic. The method for preparing the stable slow-digestion starch comprises the following steps of: treating rice starch milk for 25 to 30 minutes under the ultrasonic conditions of the frequency of 500 to 600 W and the temperature below 25 DEG C, and adding lipid (the rice accounts for 20 to 22 mass percent) for performing high temperature complex reaction for 20 to 25 minutes at the temperature of between 140 and 160 DEG C; and obtaining the product containing over 70 percent of the slow-digestion starch and of which the residual slow-digestion starch is over 95 percent in high-temperature processing treatment (at the temperature of between 90 and 110 DEG C) by adopting the short-time crystallization technology (at 4 DEG C for 12 hours). The method has the advantages of good product quality, high nutritional value, low glycemic index, low production cost, easy continuous production, no environmental pollution, wide market prospect, and high social and economic benefits.
Description
Technical field
A kind of preparation method of stable slow-digestion starch relates to the collaborative slow-digestion starch product of producing of ultrasonication technology and chemical complexing method.Belong to the treated starch manufacture field.
Background technology
Starch is important basic material in the industry such as food, medicine, chemical industry, weaving, it also is the important source of carbohydrate in the human diet, slow-digestion starch has special nutritive property, can regulate the body glucose level, improve intestinal movement, help controlling obesity, also can be used as athletic carbohydrate supplement.The slow-digestion starch processing technology mainly contains physics method, enzyme process, chemical method, complex method etc. at present.But the instable novel method of processing of develop a kind of low cost, be easy to suitability for industrialized production, being convenient to operate control and can overcome slow-digestion starch product commonly used has very necessary meaning.
Starch molecule can be degraded in the high-power ultrasonication process, has destroyed the starch branched structure, ruptures and produce more short chain amylose in part amylopectin point of crossing; Ultrasonic energy reduces the starch crystals district, improves starch chemical reaction performance, reduces the reaction times, reduces a large amount of uses of organic reagent, and degraded has the advantage of nonrandomness, and ultrasonic wave is impelled the starch chain depolymerization simultaneously, forms more line style short chain amylose.
Because intramolecular interaction, complexing can take place with some title complexs such as iodine, lipid, alcohol, tensio-active agent etc. in the line style short chain amylose, forms V-type simple helix shape complex compound.Under hot conditions, strand amylose starch and the suitable preferential very strong mixture (fusing point is at 100-120 ℃) of this thermostable type that forms of part meeting, then form V-type crystallite through crystallization treatment in short-term then, this crystallite has stronger anti-enzymolysis, its digest and decompose speed in vivo is slower, has the slow-digestion starch effect.In addition, the formation of starch-lipid complex can also improve the quality and the structural stability of starch base material, reduces stickiness, delays age of starch, can be widely used in food, medicine and other fields.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of stable slow-digestion starch, utilize ultrasonic wave depolymerization and interpolation lipid to form V-type crystal starch-lipid complex and prepare good heat resistance, the slow-digestion starch product that stability is high.
