Description

Self-mixing coarse cereal rice cake powder and preparation method thereof

Technical Field

The invention relates to the technical field of food production, in particular to self-mixing coarse cereal rice cake powder and a preparation method thereof.

Background

The coarse cereals refer to grains other than rice and wheat, and are a general term for small-variety grains, small-variety beans and potatoes. Mainly comprises buckwheat, oat, barley, wheat, millet, corn, glutinous rice, broad bean, pea, mung bean, black bean, kidney bean, small red bean and the like. China is a big agricultural country, and the resources of coarse cereals are very rich, so that the Chinese cereal is the biggest 'coarse cereal kingdom' in the world. The planting history of the coarse cereals is long, the varieties are various, and the distribution is wide. According to statistics, in 2002, the areas and the yields of buckwheat and chylomicron in China are on the 2 nd level in the world, the yield of broad beans accounts for 1/2 of the total world yield, and the yield of mung beans and small beans accounts for 1/3 of the total world yield, and the buckwheat and small beans are the main producing countries of oat, cowpea and hyacinth bean. The coarse cereals are recognized as pollution-free natural green foods, have special dietary therapy and food nourishing effects, and play an important role in modern safe health-care foods. The nutritional ingredients of protein, fat, carbohydrate, vitamins, minerals, cellulose and the like in the coarse cereals accord with the most reasonable proportion ingested by human bodies, and the coarse cereals have rich nutritional values. The traditional Chinese medicine considers that the coarse tea rice is healthy. The Huangdi's classic on medicine states that: the five cereals are used as nutrients, the five fruits are used as assistants, the five animals are used as benefits, the five vegetables are used as supplements, and the five vegetables are taken with the appropriate smell to supplement essence and qi. "it is considered that the diet can achieve the comprehensive supply of nutrition required by body health, and can strengthen body constitution and prolong life.

Nutritionals have recognized that the best diet is actually a balanced diet. The first principle of balanced diet requires that the food be as diverse as possible. Eating only the fine rice and the white flour is inconsistent with the principle of balanced diet, and eating coarse cereals such as millet, corn, buckwheat, sorghum, oat and the like. The coarse cereals contain more trace elements such as iron, magnesium, zinc and selenium than the fine grains. The value of these trace elements to human health is considerable. The contents of potassium, calcium, vitamin E, folic acid and bioflavonoid in the coarse cereals are also more abundant than that of the fine grains. However, since coarse cereals are rough in taste and not easy to digest, if they are made by a conventional method, they hardly cause appetite. Therefore, it is important to improve the taste and digestibility of coarse cereals through further processing in order to maintain the dependence of people on coarse cereal foods.

The traditional rice cold cake production process comprises the steps of rice soaking, grinding into slurry, adding lime water (calcium hydroxide) for boiling, naturally cooling and solidifying and the like. In hot summer, the rice cake is taken as a local flavor snack in Sichuan, Guizhou, Jiangxi and other areas of China, is popular with consumers for a long time, but is inconvenient and sanitary due to the complex manufacturing process, especially long cooling solidification time (5-6 h), so that the household manufacturing of the rice cake is greatly limited, and the rice cake cannot adapt to the rhythm of modern life.

Compared with the traditional rice cold cakes, the rice cold cake powder product not only solves the defects of the traditional rice cold cake making process, but also is more suitable for the rhythm of modern life. Chinese patent CN103549257A discloses a bean jelly powder and an eating method thereof, which mainly discloses that the formula of the bean jelly powder comprises the following raw materials by mass: 40-99.5% of starch, 0-59% of rice flour and 0.5-2.5% of alkali. It can be seen that the invention needs to promote the gel forming of the cake powder by edible alkali and ensure the taste of the cake by adding alkali. However, the dietary alkali has strong damage effect on the vitamins B1, B2 and vitamin C in the food and can influence the absorption and utilization of certain mineral substances by human bodies, so the cold cake powder of the invention is not beneficial to the health of the human bodies after being used for a long time.

And along with the continuous improvement of living standard, people are more and more exquisite in nutrition collocation to the food, and rice is one of people's staple food, and it is convenient to cook, and the shape becomes the ellipse, and it is slick and sly to feel, fine and smooth delicious to eat. However, the rice is single in nutrition, the lysine content is very low, if the rice cannot be supplemented by other things, the utilization rate of protein of people taking the rice as staple food is reduced, and the rice not only influences the growth of children, but also brings disadvantages to the metabolism of adults. Therefore, foods which are rich in nutrient elements, pure natural and original ecology and good in taste are more and more popular with people.

However, in the prior art, the problem that eaters need to mix the required flour amount and water amount by themselves when eating the cake flour is solved, and the eaters are difficult to control the reasonable amount of the cake flour and water in the mixing process, so that the cake made by purchasing the cake flour is difficult to achieve the expected good-eating effect.
