Vitamin A is a fat-soluble vitamin, an organic compound whose chemical formula is C20H30O. It is stable to heat, acid, and alkali, and is easily oxidized. Ultraviolet rays can promote its oxidative damage. Vitamin A includes A1 and A2, and A1 is retinol. Vitamin A2 is 3-dehydroretinol, and its physiological activity is 40% of that of vitamin A1.

Vitamin A has a variety of physiological functions such as promoting growth, reproduction, maintaining normal secretion of bones, epithelial tissue, vision and mucosal epithelium, and vitamin A and its analogs have the effect of preventing precancerous lesions. Deficiency manifests as growth retardation, impaired dark adaptation and night blindness. Dry eye disease occurs due to dryness, desquamation, hyperkeratosis, and decreased secretion of lacrimal glands of epidermal and mucosal epithelial cells. In severe cases, corneal softening, perforation and blindness occur. Respiratory epithelial cells become keratinized and lose their cilia, making them less resistant to infection. The recommended intake of vitamin A (RNI) for adults in my country is 800 μg retinol activity equivalent per day for men and 700 μg retinol activity equivalent per day for women. [2] Foods rich in vitamin A include liver, egg yolk, and milk powder of poultry and livestock. Carotene can be converted into vitamin A in the mucosa of the small intestine, red-yellow and dark green vegetables. Fruits contain more carotene.
Advantages of whole grain microwave baking and curing equipment
What are the grains?
When it comes to the grains and grains, many people are relatively unfamiliar. In the "Yellow Emperor's Canon", the grain is called: "glutinous rice, adzuki beans, wheat, soybeans, and astragalus", while in "Meng Teng Wengong", the grain is called "rice,"é», 稷, 麦, è½", in the Buddhist rituals, also known as the grain as "barley, wheat, rice, adzuki beans, flax", and then Li Shizhen in the "Compendium of Materia Medica" recorded 33 kinds of cereals, beans have 14 A total of 47 species. There is also a saying that the grain refers to five types of crops, namely "hanging, vine, root, horn, and ear".
In modern Chinese, the commonly used grain refers to: rice, wheat, soybeans, corn, and potatoes. It is also customary to refer to foods other than rice and flour as miscellaneous grains, and grains and grains are also referred to as food crops, so grains are also The collective name for food crops.
The ancient word "grain" generally refers to: millet, beans, hemp, wheat, rice; at the same time, grains can also be a general term, referring to crops or agricultural products. It can be extended to foods and drinks containing cereals or indigenous crops.
Why do so many people choose the microwave curing baking equipment?
1. Microwave drying and curing baking equipment has high energy conversion efficiency and fast heating speed. The microwave oven itself does not generate heat, but the microwave energy penetrates the material, causing the polar molecules in the material to rub against each other to generate internal heat.
2. The liquid inside the material to be processed is instantaneously heated and vaporized, and pressurized and expanded; and the expansion of the polymer in the component is denatured by the expansion force of the gas, and becomes a microporous material having a network structure and shape.
3, while microwave baking, accompanied by bactericidal effect.
4. Microwave sterilization is carried out under the dual action of microwave thermal effect and non-thermal effect. Compared with conventional temperature sterilization, it can obtain satisfactory sterilization effect at a lower temperature and in a short time.
5, the general sterilization temperature is about 80 ° C, the treatment time is 3 to 5 minutes, and can save the nutrients to a large extent
Characteristics of the whole grain microwave baking and curing equipment:
1. High energy conversion efficiency and fast heating speed. The microwave oven itself does not generate heat, but the microwave energy penetrates the material, causing the polar molecules in the material to rub against each other to generate heat. Therefore there is no energy loss.
2. The effect of puffing is obvious. The rapid heating effect of the microwave makes the water molecules inside the material vaporize rapidly and achieve the purpose of puffing.
3, low temperature sterilization, less loss of nutrients. Microwave sterilization is carried out under the dual effects of thermal and non-thermal effects of microwaves, and satisfactory sterilization can be obtained at a lower temperature and in a shorter period of time than conventional temperature sterilization.
4, easy to use and operate. Microwave power and conveyor speed can be adjusted steplessly, without thermal inertia, can be opened and stopped, easy to control.
5, energy saving and environmental protection. Microwave heating is the heat generated by the heated object itself, no energy loss, compared with other methods of maturation and power saving more than 30%, and no pollution occurs in the entire production process.
The range of cereals microwave curing baking equipment can also be applied:
1. Dry sterilization of beef meat, dried fish, meat shop, shrimp and other meat types.
2. Low-temperature drying sterilization of various fruits, nuts, fruit slices, beans and vegetables
3. Dry sterilization of mushroom, mushroom, fungus and other mushroom species
4, tea leaves, dry, loose and moist leaves
5, Chinese herbal medicine Chinese medicine decoction pieces, granules dry sterilization
6. Sterilization of dried vegetables, instant noodles, and drying of tobacco
7, soybean, rapeseed dislocation
8, bean products sterilization and preservation
9, silkworm cocoon drying
10. Drying and sterilization of other granular materials
