Secondly, background art:
the coarse cereals are important food grains for adjusting dietary structure and avoiding excessive or insufficient dietary nutrition caused by long-term single consumption of staple food. The coarse cereals have "Five high and one low ", namely: high content of trace elements, high dietary fiber, high alkali-acid neutrality, high vitamin content, high ratio of protein to amino acids, and low calorie. The coarse cereals are food with health care function in a certain sense, and have different nutrition effects and also have the effects of improving the health condition of human bodies and reducing the risks of diseases to a certain extent. The health care effect of the coarse cereals is embodied in the contained special components: one is vitamin BlThe content of the coenzyme is high, and the coenzyme can be used as a coenzyme to participate in carbohydrate metabolism, promote digestion and maintain the normal function of a nervous system; the second is that the coarse cereals contain more dietary fibers, are called as 'seventh nutrient' of human body, are rich in rutin, isoflavone, choline, saponin and other substances, can reduce sugar, reduce fat, lose weight, relax bowels, detoxify, prevent cancer and enhance disease resistance; and thirdly, the coarse cereal food is alkaline, and has the functions of neutralizing the acidic environment of a human body, relieving fatigue, increasing physical strength and enhancing immunity. The coarse cereals are the bases of dietary pagodas, are the best basic food and are the most economic and effective health-care food.
The coarse cereal porridge is one of the main ways of daily coarse cereal products for people, has a thousand years history in China, and has the health-preserving effects of resisting cold, warming the body, controlling the weight, preventing constipation, protecting blood vessels, stabilizing blood sugar and the like. At present, scholars report that the death rate of 5 percent and the probability of suffering from cardiovascular diseases of 9 percent can be reduced by drinking one bowl of coarse cereal porridge decocted by about 28g of whole grains every day. Although the coarse cereal porridge is good to drink, the coarse cereal porridge is difficult to cook, and mainly has the following problems that firstly, the coarse cereal porridge needs to be soaked in advance or cooked for a long time for eating, the cooking time of different coarse cereal raw materials is inconsistent, the coarse cereal porridge is very inconvenient to eat, and the time and the labor are wasted; secondly, the variety of the coarse cereal porridge is too single, people only select one or more coarse cereals to simply match and eat, and the coarse cereal porridge cannot be scientifically and complementarily matched and eaten according to the nutritional ingredients, functional properties and food health preserving principle of different coarse cereals; thirdly, the processed and pretreated coarse cereal porridge material has the phenomenon of rice-water separation after being rehydrated or boiled again, and the viscosity and the flavor of the porridge liquid are obviously reduced. Therefore, people desire a coarse cereal instant porridge product which is suitable for the needs of the people, has certain auxiliary health-care effect, is nutritional and healthy, can be quickly and conveniently cooked at the same time and has the flavor of the traditional cooked porridge.
At present, various coarse cereal instant porridge products prepared by using coarse cereals as main raw materials in the market are various, the product forms are diversified, and the preparation processes and the preparation methods are different. Patent CN105011011A discloses an instant coarse cereal porridge and a manufacturing method thereof.
