A Special Nutritional Food for Relieving Physical Fatigue and its Preparation Method

TECHNICAL FIELD

The invention relates to a food, in particular to a special nutritional food with the function of relieving physical fatigue, and also relates to a preparation method of the special nutritional food.

BACKGROUND

Black food is a traditional agricultural product resource for both medicine and food in China.

The Ming Dynasty medical book The Secret Book of Prolonged Life records that "taking black beans can make people grow skin, benefit colour and fill essence, such as strength, deficiency and food, and mystery". According to the Classic of Herbal Medicine, black sesame has the effects of "winning in the main injury, replenishing five internal organs, benefiting qi, growing muscles and filling marrow and brain". "Compendium of Materia Medica" said that taking black sesame seeds for 100 days can eliminate all chronic diseases. One year, you will not be hungry; two years later, your white hair will turn black; and three years later, your teeth will regress. Ancient agricultural medical books record that black rice "nourishes yin and kidney, keeps fit and warms stomach, improves eyesight and promotes blood circulation”. Motherland medicine believes that black food can tonify the kidney, and the kidney is the "source of life", so black food has the functions of strengthening the body resistance, delaying aging and strengthening the body. Modern research shows that black food contains natural melanin, protein, amino acids, various trace elements and vitamins, which can regulate some physiological functions of human body and is an ideal raw material for developing natural health food.

Dimocarpus longan, commonly known as "longan", is a rare specialty in the south subtropical zone of China. In history, there is a saying of "longan" in the south and "ginseng" in the north. Longan has the effects of benefiting the heart and spleen, invigorating gi and blood, and tranquilizing the mind. It is mainly used to treat debilitating diseases, insomnia, forgetfulness, fright and other diseases. In the Ming Dynasty, Li Shizhen once had the evaluation that "Longan is good for resources”. Modern research shows that longan pulp water extract can improve the endurance of mice and has the function of anti - oxygen free radicals.

Meanwhile, human experiments show that it can significantly enhance athletes' sports ability and anti - fatigue ability, and can be used as the main food source to relieve physical fatigue.

As a daily nutritional supplement or dietary substitute, special nutritional food has the advantages of comprehensive nutrition, strong functionality and quick convenience. At present, the nutritional meals on the market mainly provide comprehensive nutritional support for the pathological characteristics of people with various diseases, but lack of functionality, such as the unique functions of relieving physical fatigue, etc. However, there are functional nutritional meals, and their nutritional supply is relatively simple, which greatly limits the range of users.
