Description

Mixed bean powder, mixed bean composition prepared from mixed bean powder and application of mixed bean composition
Technical Field
The invention relates to a preparation method of a mixed bean composition and application of the mixed bean composition in preparation of slowly digestible food.
Background
In recent years, with the rapid development of Chinese economy, the great changes of the dietary structure and the life style of people lead to the remarkable changes of human disease spectrum and death spectrum, and the problems of chronic non-infectious diseases (chronic diseases) such as diabetes, hypertension, coronary heart disease, cerebral apoplexy and the like are increasingly severe, so that the chronic non-infectious diseases become the main causes of death and disability of residents in China. Diabetes mellitus, a common chronic disease, is currently growing at an alarming rate, and particularly type II diabetes mellitus has become one of three chronic diseases that seriously affect the physical and mental health of human beings. Starch is used as the main component of grain food, and the digestibility of the starch is closely related to the sugar metabolism of diabetics. Therefore, how to control the digestibility of starch has become a key to the treatment and prevention of diabetes.
Regarding the digestibility of starch, Englyst, a british physiologist, divides it into fast-digestible starch (RDS), slow-digestible starch (SDS) and Resistant Starch (RS). RDS refers to starch that is rapidly digested and absorbed in the small intestine (<20 min); SDS refers to starch (20-120min) which can be completely digested and absorbed in small intestine, but has a slow speed; RS is starch that is not digestible and absorbable in the human small intestine. The SDS is degraded slowly in small intestine, prolongs glucose release, maintains stable blood sugar, is low blood sugar starch with both nutrition and function, and can prevent and treat diabetes, cardiovascular diseases, obesity and other diseases. Therefore, it is of great nutritional importance to study how to prepare high quality SDS and food products comprising SDS.
In recent years, it has become a common strategy to decrease the digestibility of starch by altering the crystalline structure of the starch molecule by increasing the amylose content. For example, CN201811492438.0 and CN201811385328.4 are used for producing short-chain amylose by enzymatic debranching, and then the resistant starch content is improved by forming a starch-lipid complex through high-temperature lipid reaction. For example, CN201710316027.5 and CN201810830247.4 are prepared by adjusting the straight starch content through pullulan debranching enzymolysis, and combining with repeated freeze-thawing or low-temperature toughening, perfecting the starch crystal structure and enhancing the resistance to enzymes. And other phenolic substances with the amylase inhibition effect, such as CN201510851226.7, CN201710844398.0 and CN201610781168.X, can be embedded in the complex of the amylose hydrophobic spiral cavity after the debranching by enzymolysis. The disadvantages of the above methods are mainly 1) the use of enzyme preparations is expensive, the use of low temperature freezing process is not beneficial to the control of production cost; 2) the preparation process generates a large amount of wastewater, and the subsequent drying step is not environment-friendly and energy-saving; 3) some lipid-supplemented manufacturing processes also introduce organic solvents, which remain a risk of food safety.
