Problems solved by technology

The invention uses starch as a raw material, mixes it with resistant dextrin after treatment and reacts under specific conditions, can significantly increase the fiber content in resistant starch, so that the fiber content can reach more than 50%, which solves the problems in the prior art. Repeated processing many times, the fiber content is still insufficient, but this resistant starch fiber content is very high, it has little effect on blood sugar regulation, and cannot be used as a diet for diabetic patients for a long time

Embodiment 1

[0027] A method of preparation of novel resistive starch having amylase inhibiting active groups, including the steps of:

[0028] (1) 0.1 mol of palmitic acid was added to a 150 ml of three-necked flask, and the 67 ° C water bath was added to dissolve, stirred with 0.16 mol (11.6 mL) of sulfoxide, 30 min was added, and stirring was stirred for 4 hours, and after stopping the reaction, The remaining chlorinated sulfoxide was recovered under reduced pressure to obtain palmitrate acid chloride, which poured into a dry 100 mL dropping funnel, mixed, closed backup;

[0029] (2) In a three-mouth flask equipped with a stirrer and reflux condensed water, 3.38 g of potato crosslinking starch and 30 ml of pyridine, stirred so much, activated at 95 ° C for 1 h, adjust the reaction temperature to 85 ° C, 35 ml of palmitrate acid chloride, 30 min was added, 2 h, cooled to room temperature, the product was added to anhydrous ethanol, stirred, stirred, filtered, filtered, washed with ethanol an...

Abstract

The invention discloses a preparation method of a novel resistant starch with an amylase inhibitory active group, and relates to a preparation method of the resistant starch, comprising the following steps: (1) adding fatty acid into a three-necked flask and heating in a water bath at 65-69°C , add thionyl chloride dropwise under stirring, drop for 25-35min, continue stirring for 3.5-4.5h, after stopping the reaction, recover the remaining thionyl chloride to obtain fatty acyl chloride; (2) add a certain amount of potato cross-linking Stir the starch and pyridine, activate the reaction at 95°C for 1 hour, adjust the reaction temperature, add palmitic acid chloride dropwise, finish dropping after 30 minutes, react for a certain period of time, cool to room temperature, add the product to absolute ethanol, stir, and precipitate the product Analyze, filter with suction, wash with ethanol and benzene, and finally wash with water several times, and dry the filter cake under vacuum at 70°C for 24 hours to obtain the new resistant starch. The novel resistant starch has high hypoglycemic activity and can be used as food for diabetics.

Description

Technical field [0001] The present invention relates to the preparation method of resistant starch, in particular, a method and application of a new type of resistant starch having a amylase inhibited active group. Background technique [0002] Diabetes is one of the most important non-infectious diseases that endanger human health. The statistical report of the International Diabetes Federation shows that nearly 380 million people have diabetes. It is expected that the diabetic patients will reach 592 million, and the incidence of diabetes has increased year by year. Public health issues in global concern. Diabetes can also lead to some complications such as nephropathy, retinal lesions, liver injury, coronary heart disease, heart disease and peripheral nephropathy. Controlling diabetes must control blood sugar, but diabetes patients cannot be absorbed by the body due to metabolic disorders, leading to rising blood glucose after meal; in order to reduce the damage of high blood ...
