Description

Technical Field

[0001] The invention relates to the technical field of grain powder, and in particular to fruit and vegetable grain powder and a preparation process thereof. Background Art

[0002] Grain flour is a powdered substance made from various grains. The main ingredients of grain flour include wheat, corn, oats, barley, buckwheat, brown rice, lotus root and other grains. These grains are rich in nutrients, such as carbohydrates, protein, cellulose, minerals and vitamins.

[0003] After searching, it was found in a Chinese patent (publication number: CN103082189A) that "a nutritious cereal powder is characterized in that the preferred formula and weight proportions of the cereal powder are: 40-50 corn, 5-10 sticky corn, 5-10 yellow rice, 5-10 millet, 5-10 high-gluten flour, 0.2-0.5 xanthan gum, 0.2-0.4 distilled monoglyceride, and 0.01-0.03 amylase".

[0004] A Chinese patent (publication number: CN110786444A) discloses "a whole grain flour comprising the following components in parts by weight: 2-2.5 parts of coix seed, 2-2.5 parts of quinoa, 1.8-2.2 parts of black beans, 1.5-2 parts of black rice, 2-3 parts of corn, 2-2.5 parts of rice, 3-4 parts of oats, 2-2.5 parts of red beans, 2.5-3 parts of barley, 2.5-3 parts of glutinous rice, 2-2.5 parts of peas, 2.5-3 parts of millet, 2-2.5 parts of buckwheat, 60-65 parts of wheat, 3-3.5 parts of yellow rice, 3-3.5 parts of sorghum, 2-2.5 parts of dried fruit, 1.5-2 parts of mung beans, and 1-1.2 parts of foxtail millet."

[0005] Although this type of patented grain flour has certain nutritional value, it has certain defects:

[0006] First, since most of the raw materials in cereal flour (corn, millet, buckwheat, etc.) contain high levels of oil, and high-oil raw materials are easily oxidized, the risk of oil oxidation and deterioration may increase due to restrictions on packaging and storage conditions, which will not only reduce the nutritional value of the product, but may also produce unpleasant flavors and harmful substances;

[0007] Second, people are under great pressure at work, and the problem of hair loss is becoming younger and younger, mainly because the hair lacks corresponding influencing substances. Although the cereal powder on the market now has a hair care effect, the content of nutrients required for hair care (fatty acids, proteins, vitamins, minerals, etc.) is relatively low. In view of this, the present invention proposes a fruit and vegetable cereal powder and a preparation process thereof. Summary of the invention

[0008] The invention provides a fruit, vegetable and grain powder and a preparation process thereof, which solves the problem that the existing grain powder is easily oxidized and deteriorated.

[0009] The technical scheme of the present invention is as follows: a fruit, vegetable and grain powder comprises the following raw materials: 10-15g oats, 12-25g egg yolk fruit, 8-24g mulberries, 14-18g jujube seeds, 5-8g longans, 8-16g walnuts, 7-15g lotus seeds, 12-20g lotus roots, 10-18g yam, 11-14g lilies, 7-10g cucumber seeds, 10-18g flax seeds, 12-16g black sesame seeds, 14-20g black beans, 16-24g red beans, 20-25g black rice, 15-23g stalk rice, 16-21g adzuki beans, 14-17g sword beans, 12-16g ganoderma lucidum, 21-26g alpinia oxyphylla seeds, 22-30g corn, 22-30g fried coix seeds and 20-30g bitter buckwheat.

[0010] The present invention also provides a process for preparing fruit, vegetable and grain powder, comprising the following steps:

[0011] S1: Raw material cleaning: clean the surface of all raw materials, and then pre-treat, wash, soak and drain to ensure that there are no impurities on the surface of the raw materials;

[0012] S2: Low temperature drying: All raw materials are dried in low temperature drying equipment. The specific implementation process is as follows:

[0025] (2) Take the mulberries out of the rice washing water and soak them in salt water for 5-10 minutes to remove bacteria on the surface of the mulberries;

[0026] (3) Take the mulberries out of the salt water and wash them. At the same time, add a small spoonful of flour or starch to use its strong adsorption capacity to absorb impurities such as insect eggs and dust on the surface of the mulberries.

[0027] Preferably, in S2, during the process of loading the raw materials into the drying bin, a grain distributor may be used to evenly distribute the broken grains and impurities, thereby further improving the uniformity of the airflow.

[0028] Preferably, in S2, during the drying process, the moisture content and temperature of the grains need to be checked regularly to ensure the drying effect. A sampler can be used to take samples from different parts of the drying bin and then tested. If it is found that the moisture content or temperature of the raw materials does not meet the requirements, the drying parameters need to be adjusted in time.

[0029] Preferably, in S4, the specific implementation process of microwave sterilization is as follows:

[0030] (1) Place the raw material powder to be sterilized evenly on the conveyor belt of the microwave sterilization equipment to ensure that the thickness and distribution of the grain powder are uniform to avoid uneven sterilization;
