Description

Multi-grain extruded food and preparation method thereof
Technical Field
The invention belongs to the field of food, and particularly relates to a multi-grain extruded food and a preparation method thereof.
Background
With the improvement of the living standard of people and the difference of physique of different people, the requirements of people on staple food gradually tend to functionality and customization, and the requirements on taste are increasingly diversified. The traditional pure wheat product meets the requirements of people on taste diversification to a certain extent by adding sugar and stuffing, adopting frying, baking and the like, but directly damages the health of consumers; for people with different constitutions and different consumption preferences, the traditional wheat flour cannot provide differentiated products.
The contents of trace elements and vitamins in wheat flour are enhanced, the requirements of human bodies are basically met, but the protein titer and the dietary fiber content are not improved, the glycemic index is not reduced, and a staple food flour with comprehensive nutrition and low glycemic index is still expected by the public.
The grains contain rich nutrient elements, which meet the requirements of modern people on food, but many foods eaten by people are deeply processed, and the loss of nutrient components carried by the grains is large. The multi-grain raw materials are inconvenient to eat directly and have poor taste.
Disclosure of Invention
The invention aims to provide a multi-grain extruded food with rich nutrition and good taste and a preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
a multi-grain extruded food comprises the following raw materials in parts by weight: 10-20 parts of rice, 25-35 parts of corn flour, 8-12 parts of black rice, 10-15 parts of rye flour, 6-10 parts of wheat flour, 3-8 parts of oat flour, 3-8 parts of bean flour, 3-8 parts of starch, 3-8 parts of crystalline fructose, 1-3 parts of calcium carbonate and 2-4 parts of white granulated sugar.
The multi-grain extruded food comprises the following raw materials in parts by weight as a preferred embodiment: 12-18 parts of rice, 28-32 parts of corn flour, 9-11 parts of black rice, 12-14 parts of rye flour, 7-9 parts of wheat flour, 4-6 parts of oat flour, 4-6 parts of bean flour, 4-6 parts of starch, 4-6 parts of crystalline fructose, 2-3 parts of calcium carbonate and 2-3 parts of white granulated sugar.
Preferably, the feed comprises the following raw materials in parts by weight: 15 parts of rice, 30 parts of corn flour, 10 parts of black rice, 12 parts of rye flour, 8 parts of wheat flour, 5 parts of oat flour, 5 parts of bean flour, 5 parts of starch, 5 parts of crystalline fructose, 2 parts of calcium carbonate and 3 parts of white granulated sugar.
The rice is also called rice, and contains nearly 64 percent of nutrient substances in the rice and more than 90 percent of nutrient elements required by human bodies. The rice is sweet in taste and neutral in nature, has the effects of tonifying middle-jiao and Qi, strengthening spleen and stomach, replenishing vital essence and strengthening mind, harmonizing five internal organs, promoting blood circulation, improving hearing and eyesight, relieving restlessness, quenching thirst and stopping diarrhea, is called as the first of five cereals, is a main food crop in China, and occupies about one fourth of the cultivation area of the food crop.
Corn flour is produced by grinding corn, which is also called corn flour, into flour after removing bran. The corn flour mainly contains protein, starch, fat, vitamins, minerals and other nutrient components. The corn flour has the functions of invigorating spleen, promoting diuresis, regulating the middle warmer, regulating stomach function and inducing diuresis, and is very suitable for people with spleen deficiency. The content of cellulose in fresh corn is 6-8 times of that of refined rice and refined flour, and can reduce the concentration of cholesterol in blood, so as to prevent cardiovascular and cerebrovascular diseases.
The black rice is a kind of rice for both medicine and food, and belongs to the glutinous rice category. The black rice is neutral in nature and sweet in taste, and has the effects of appetizing, tonifying middle-jiao, invigorating spleen, activating blood and improving eyesight. Can resist aging; supplementing various mineral materials such as protein, manganese, zinc, etc. required by human body.
The rye powder contains insoluble cellulose, isoflavone and trace elements, and has anticancer and antiaging effects. In addition, the trace element fluorine contained in rye is an important component of bones and teeth, and the rye and products can prevent dental caries, osteoporosis of the old and the like after being eaten frequently.
Wheat flour is flour processed from wheat, and is generally flour obtained by extracting bran. Wheat flour contains protein, starch, fat, vitamins, inorganic salt, etc. The content of carbohydrate in wheat flour is above 70%, and the wheat flour mainly comprises starch, cellulose and other saccharides, and is a main source of human energy.
Oat flour is highly refined from flour made from oat groats. Oat has high nutritive value, is rich in protein, unsaturated fatty acid, mineral substances and various vitamins, and also contains rich beta-glucan. Has effects in reducing blood cholesterol, controlling blood sugar, relieving constipation, and preventing osteoporosis.
The bean powder is a food prepared by baking and pulverizing soybean. The bean flour contains amino acids essential to human body, wherein the content of lysine in the dry grain is the most reasonable and closest to the ratio required by human body in the plant food. The bean flour contains a large amount of cellulose, can effectively prevent excessive absorption of sugar and reduce sugar content, thereby preventing diabetes and being a good food essential for diabetics in daily life.
The crystalline fructose is monosaccharide, is the sugar with the highest chemical activity in saccharides, and is naturally present in honey, and compositae plants such as Jerusalem artichoke, chicory and the like. The fructose has higher sweetness, fruit fragrance and low calorific value, is metabolized faster than glucose in vivo, is easy to be absorbed and utilized by organisms, has smaller influence on blood sugar without depending on insulin, can promote the growth and reproduction of beneficial bacteria such as bifidobacteria in human bodies, inhibit the growth of harmful bacteria, improve the functions and metabolism of intestines and stomach of people, reduce blood fat, avoid decayed teeth, and is an ideal sweetener for foods of diabetes patients, obesity patients and children.
