Description
Technical field
The present invention relates to a kind of preparation method of lotus seeds resistant starch.
Background technology
Retrograded Starch RS3, it is to cool down retrogradation after starch gelatinization again to be formed, this kind of starch starch point during retrogradation
Son reassembles into orderly crystalline texture, enzyme effect is hindered in the glucoside bond of crystal region, so as to have resistance to enzymolysis.
RS3 is beneficial to health, can promote gut metabolism, increases intestinal contents content, particularly short-chain fat acid content, can
Blood glucose after having eaten index and insulin secretion are reduced, controls the blood-sugar content of II diabetes mellitus types；It may additionally facilitate body pair
The absorption of calcium, magnesium ion, prevents fat accumulation.Simultaneously in food processing, RS3 is because heat endurance is compared to other types
Resistant starch it is strong, used often as food additives, RS3 can improve fried food color and luster；Possess Yoghourt simultaneously
Preferably organoleptic quality, increase bread water content, so that bread is softer.
Because RS3 possesses higher commercial value, turn into the study hotspot of domestic and foreign scholars at present.RS3 at present
Preparation method has autoclave process, chemical enzymatic isolation method, microwave radiation, Extrusion and ultrasonic assistant autoclave process etc.；Learn
Person using microwave method by the raw materials such as corn, mung bean, potato be made resistant starch, Hao Zhenghong etc. smashed with ultra micro-microwave is used in conjunction
Technology prepares mung bean resistant starch, and resistant starch yield is brought up into 32.80% by process optimization；The use such as Xia Dedong microwave-
Enzymolysis composite algorithm prepares Potato Resistant Starch, and the resistant starch acid resistance prepared is stronger, can be widely applied to acid food
Product.
The nutritious lotus seed that Fujian Province is produced Jianning County enriches, and medical value is high, is one of traditional medicine-food two-purpose food.
Research finds that content of starch is higher in lotus seeds, and more than lotus seeds dry weight 50%, and amylose is more up to 40%
More than, close to green starch content；Zhuo Xiaohong is studied lotus seed starch molecular characterization and found, lotus seed starch have main chain it is long,
The characteristics of side chain is short, degree of branching is few, causes lotus seed starch easy to aging.Therefore, lotus seeds there is good resistant starch to prepare latent
Energy.
The content of the invention
The present invention proposes a kind of preparation method of lotus seeds resistant starch.
A kind of preparation method of lotus seeds resistant starch, comprises the following steps：
（1）Take lotus seeds, starch milk, deionized water standby, above raw material is commercially available；
（2）Fresh lotus seed is taken, the deionized water of 2 times of quality of addition, which is placed in mixer, blends into lotus seeds slurry；
（3）Slurries cross 100 mesh sieve gauzes, staticly settle 8h after adding 2 times of deionized water dilution stirrings, keep temperature in the process
20 DEG C of degree, to prevent slurries from turning sour；
（4）The abandoning supernatant after starch completely sedimentation, precipitation surface is cleaned with deionized water, is again stirring for after precipitation same
At a temperature of stand, until starch is layered completely with water, abandoning supernatant；
（5）Oven for drying to the starch moisture content that 45 DEG C are placed in after cleaning precipitation surface with deionized water is 11.8%, standby；
（6）The lotus seed starch addition appropriate amount of deionized water of drying is configured to the starch milk solution of various concentrations, through being sufficiently stirred
Afterwards, immediately in microwave equipment with certain Power Processing for a period of time；
（7）Wait that gelatinized corn starch is taken out after bringing back to life is cooled to room temperature, refrigerates 12h in 4 DEG C of refrigerators, after retrogradation terminates, in 50 DEG C of bakings
It is dry；
（8）By step（7）Product crushes, sieved, after purification, produces lotus seeds resistant starch.
Preferably, the W of microwave power 400, time 120s.
Preferably, the starch concentration is 35%.
A kind of preparation method of lotus seeds resistant starch of the present invention, starch are fully gelatinized, and easily form double spiral shells of resistance to enzymolysis
Structure is revolved, its molecular diffusion rates is fast, and aggregation resistant starch yield is high.
