Preparation method of composite nutritional breakfast powder suitable for people with high blood pressure, high blood sugar and high blood sugar
Technical Field
The invention belongs to the technical field of food processing, and relates to a preparation method of composite nutritional breakfast powder suitable for people with high blood pressure, high blood sugar and high blood sugar.
Background
In recent years, health problems of young office workers have been receiving increasing social attention, particularly in cities where the pace of work and life is fast. Many people are still young and have strong strength and dry strength, sacrifice normal rest time, overtime and overtime, and greedy black at the beginning; for the sake of better performance, the wine container wine box is free in each catering bureau, luxurious eating and overeating, smoking and alcoholism; or sitting in front of the computer for more than 7 and 8 hours. When these conditions are accumulated to a certain extent, the body will be eaten slowly, and the "sub-health" state will appear, especially the problem is more and more prominent (three high means hyperglycemia, hypertension and hyperlipidemia), and the trend is gradually younger.
Ginkgo is a gymnosperm, which is one of the unique ancient and precious tree species in China and is called as "activating stone". The number of the gingkoes cultivated and planted in China is the first in the world and is about 75 percent of the total amount in the world. The gingko nut has rich nutrition, contains protein, starch, vitamins, calcium, potassium, selenium and other elements, and is taken as a good product for preserving health and prolonging life. It is worth mentioning that ginkgo also contains physiologically active substances, such as: flavone, ginkgol and the like, wherein the flavone has the functions of reducing blood pressure, reducing blood viscosity, eliminating free radicals, improving memory and the like. The purple corn is a treasure in purple (black) corn family, so the purple corn is also named as 'black corn', and the particle shape of the purple corn is similar to that of pearl, so the purple corn is called 'black pearl'. The purple corn contains eighteen amino acids, 21 trace elements necessary for human bodies, extremely high phenolic substances and anthocyanin, and has the effects of promoting blood circulation, reducing serum cholesterol, preventing cardiovascular and cerebrovascular diseases, delaying senescence and the like.
The soybean dietary fiber is a general term for macromolecular saccharides which cannot be digested by human digestive enzymes, and mainly comprises cellulose, pectin, xylan, mannose and the like. The dietary fiber can not provide any nutrient substances for human bodies, but has important physiological functions for the human bodies and is indispensable to healthy diet. Dietary fiber plays an important role in maintaining the health of the digestive system, such as lowering plasma cholesterol, regulating gastrointestinal function and insulin levels, and preventing cardiovascular diseases, cancer, diabetes and other diseases.
The hawthorn is stone fruit, hard in stone, thin in pulp, slightly sour and astringent in taste, has the effects of reducing blood fat and blood pressure, strengthening heart, resisting arrhythmia and the like, and is a good medicine for tonifying spleen, stimulating appetite, promoting digestion, removing stagnation, promoting blood circulation and reducing phlegm. The red dates are warm in nature and sweet in taste, and have the effects of tonifying qi and blood, strengthening spleen and stomach, reducing serum cholesterol, improving serum albumin, protecting liver and the like. The red raspberry, also known as raspberry, is called gold fruit, and its anti-aging substance SOD (superoxide dismutase), anti-cancer substance (tannic acid) and vitamin E contents are the first of all kinds of fruits. The natural superoxide dismutase and the vitamin E are excellent human body scavenger, can eliminate a large amount of harmful metabolites generated by a human body, improve the immunity of the human body, fundamentally improve the internal environment of the human body, and achieve the purposes of maintaining beauty, keeping young and prolonging life. The raspberry can effectively protect the heart and prevent cardiovascular and cerebrovascular diseases such as hypertension, vessel wall atherosclerosis, cerebrovascular sclerosis rupture and the like after being eaten for a long time.
