Problems solved by technology

Another example is the invention patent "Preparation Method of a Starch Fatty Acid Complex" (publication number CN104961837A), which discloses a method for preparing corn starch-lipid complex by combining pullulanase with wet heat treatment. Long, the production process needs to kill enzymes and centrifuge for many times, the process is cumbersome, the composite index of the compound is low, it cannot meet the requirements of industrial continuous production, and the processing technology is essentially different from this patent

Embodiment 1

[0035] A preparation method of lotus seed starch-lipid complex with anti-digestion function, specifically:

[0036] (1) Extraction of lotus seed starch: extract lotus seed starch from fresh lotus by washing;

[0037] (2) Centrifugal drying: The starch treated in step (1) was centrifugally dehydrated, dried in an oven at 55°C for 10 hours, and crushed through an 80-mesh sieve;

[0038] (3) Ultra-high pressure-enzymatic modification: Starch and water are prepared into 12wt% starch milk, put into a polypropylene vacuum bag and sealed with a vacuum packaging machine, shake well and place in an ultra-high pressure processing device (280MPa) for treatment, the pressure holding time is 20min; the starch milk obtained by the ultra-high pressure treatment is added to the citric acid-sodium citrate buffer solution with a pH of 5, and then 3 u / g of pullulanase enzyme solution is added, sealed in a constant temperature water bath and shaken. React in the bed for 5 h, use 4wt% NaOH to adj...

Embodiment 2

[0049] A preparation method of lotus seed starch-lipid complex with anti-digestion function, specifically:

[0050] (1) Extraction of lotus seed starch: extract lotus seed starch from fresh lotus by washing;

[0051] (2) Centrifugal drying: The starch treated in step (1) was centrifugally dehydrated, dried in an oven at 50°C for 12 hours, and crushed through an 80-mesh sieve;

[0052] (3) Ultra-high pressure-enzymatic modification: Starch and water are prepared into 10wt% starch milk, put into a polypropylene vacuum bag and sealed with a vacuum packaging machine, shake well and place in an ultra-high pressure processing device (300MPa) for treatment, the pressure holding time was 30 min; the starch obtained by the ultra-high pressure treatment was added to the citric acid-sodium citrate buffer solution with a pH of 5.5, and then 4 u / g of pullulanase enzyme solution was added, sealed in a constant temperature water bath and shaken. React in the bed for 5 h, use 4wt% NaOH to ad...

Abstract

The invention relates to a method for preparing a lotus seed starch-lipid compound with an anti-digestion function, and belongs to the field of modified starch processing. The method comprises the following main steps: extracting lotus seed starch, performing centralfgual drying, ultra-high pressure-enzymic method modification, lipid pretreatment, microwave compounding, ultra-high pressure treatment, low-temperature cooling crystallization, alcohol leaching centrifuging and freeze-drying, crushing, packaging, and testing the digestive performance. As the lotus seed starch is treated by the ultra-high pressure-enzymic method modification technique, the contents of straight-chain starch and porous starch are increased, and the lotus seed starch can be relatively easily compounded with lipid; the starch which is treated by the enzymic method can be compounded with the lipid by the microwave method with the combination of ultra-high pressure treatment, and moreover formation of the V-type starch-lipid compound can be further promoted by the low-temperature cooling crystallization technique, so that the compound is relatively good in anti-digestion property. Compared with a starch-lipid compound which is prepared by a conventional chemical method, the lotus seed starch-lipid compound provided by the invention is relatively high in security, high in compounding index, relatively good in anti-digestion property, and has good application prospects as the satiety can be provided and the blood sugar can be reduced as well when the compound is added into food.

Description

technical field [0001] The invention belongs to the technical field of modified starch processing, and in particular relates to a preparation method of lotus seed starch-lipid complex with anti-digestion function. Background technique [0002] In recent years, with the continuous improvement of people's living standards, people pay more and more attention to nutrition and health. Due to the increasing proportion of metabolic syndrome related to insulin resistance caused by poor eating habits such as diabetes, obesity, high blood pressure and coronary heart disease, it has seriously affected people's health, and the public has higher and higher requirements for nutritious diet. British scientists Englyst et al. divided starch into easily digestible starch (RDS), slowly digestible starch (SDS) and resistant starch (RS) according to in vitro simulated digestion characteristics and starch bioavailability. Among them, foods with certain digestive characteristics (including a cer...
