Description

Instant porridge and preparation method thereof
Technical Field
The invention relates to the field of food processing, in particular to instant porridge and a preparation and eating method thereof.
Background
With the development of society and the faster and faster pace of life of people, in order to save time, the demand on fast food is more and more, especially for breakfast food (such as instant porridge), the morning work time can be saved, but in the current instant porridge, the defects that the nutrient content is rich but unbalanced, the digestion is not easy, the obesity is easy to cause and the like exist, so that the instant porridge not only has no benefit on the health of a human body, but also affects the beauty of the human body. Therefore, it is desirable to provide an instant porridge which is healthy, weight-losing, balanced in nutrition and easy to digest, and meets the needs of people.
Rice is one of the staple foods of human beings, and according to modern nutritional analysis, the rice contains protein, fat, vitamin B1, A, E and a plurality of minerals. Edible rice has high nutritional value, but the content of lysine and threonine in rice protein is low, so the edible rice is not complete protein, the content of fat in the rice is low, and the fat in the rice is mainly concentrated in rice bran, so the edible rice cannot absorb excessive fat and protein to cause body fatness, but other substances are needed to supplement certain amount of nutrient substances which are low in the rice and are needed by a human body.
The oatmeal is a food processed by taking wheat as a raw material, and is rich in fiber, vitamins and mineral substances, but the fat content is low, and the intake of the mineral substances is also helpful for controlling fat, so that the oatmeal helps a human body to intake nutrient substances and has the effects of slimming and losing weight.
Oats, also known as brome, are generally classified into two major types, namely a hull type and a bare grain type. The oat has extremely high nutritional value, has the health-care effects of reducing blood sugar, blood fat and blood pressure, improving constipation, losing weight and the like, and is a health food which gives attention to nutrition and does not cause obesity especially for office workers who are often in a nervous state.
Millet contains rich iron, protein, vitamin B complex, calcium, potassium, fiber and the like, particularly the content of the protein in the millet is very high, generally between 5 and 20 percent, and the average content is 10 to 12 percent, and the quality of the protein in the millet is usually better than that of wheat, rice and corn, so if the millet is added into the instant porridge, the shortage of the content of the protein in other components (such as corn, wheat and rice) can be made up.
The soybeans are rich in protein, generally reach about 40 percent, and the best quality can reach about 50 percent, which is equivalent to more than 2 times of lean pork and 3 times of eggs, wherein the content of lysine is high, and each 100 g of soybeans contain about 35.8 mg of iron, 418 mg of phosphorus, and vitamins A, B1, B2 and D, E.
Therefore, the instant porridge which takes rice flour, oatmeal, oat, millet, soybean and corn as raw materials and has balanced nutrition and weight reducing effect is hopeful to be provided.
In addition, at present, the preparation of instant porridge is generally to directly cure raw material particles and pack the raw material particles to obtain instant porridge, but various ingredients are not mixed together to prepare instant porridge particles with uniform nutrition, and certain defects exist in the production process, so that the preparation method of instant porridge is expected to meet the market demand.
Disclosure of Invention
Therefore, the invention provides instant porridge and a preparation and eating method thereof, which can solve at least part of the problems.
According to one aspect of the present invention, there is provided a method for preparing instant porridge, the preparation method requiring raw materials comprising by weight: 25-35 parts of rice flour, 15-25 parts of oatmeal powder, 15-25 parts of oat powder, 5-15 parts of millet powder, 5-15 parts of soybean powder and 5-15 parts of corn flour.
According to the preparation method of the instant porridge, the instant porridge is prepared by taking the rice flour, the corn flour, the soybean flour, the oatmeal powder, the oat powder and the millet powder as raw materials, wherein various nutrient elements in the rice flour, the corn flour, the millet powder and the soybean flour are mutually supplemented, matched and supplemented, in addition, the most scientific and effective proportioning range is obtained through a large number of experiments, protein, fat, vitamin and the like required by a human body are provided, and the oatmeal powder and the oat powder are added to provide fiber, vitamin and mineral substances to help to control the fat, so that the instant porridge according to the invention can meet the requirements of the human body on various nutrient components, can not cause the human body to be fat due to the intake of nutrient substances, and achieves the purpose of healthy diet.
Alternatively, according to the preparation method of the present invention, 100% of the fine powder particles of the rice flour, the oatmeal flour, the oat flour, the millet flour, the soybean flour and the corn flour can pass through a 60-mesh sieve, and more than 92% can pass through a 100-mesh sieve.
According to the preparation method of the invention, 100% of various fine powder particles can pass through a 60-mesh sieve, and more than 92% of the fine powder particles can pass through the 100-mesh sieve, so that the prepared instant porridge has fine and smooth mouthfeel and good appearance, and the human body can better and faster absorb various nutritional ingredients.
Alternatively, the preparation method according to the present invention comprises the steps of:
s1100, mixing and burdening: adding water into the ingredients, stirring, and uniformly mixing;
s1200, a pre-curing treatment step: heating the uniformly mixed ingredients in steam at a temperature of less than 110 ℃ for 3-4 minutes to ensure that the temperature of the ingredients is 85-95 ℃, the water content is 30-35 percent and the predetermined curing degree is reached;
