Description

Technical Field

[0001] The invention belongs to the technical field of edible oils, and in particular relates to a formula edible oil capable of enhancing memory and improving brain degeneration and a preparation method thereof. Background Art

[0002] Edible oil can supplement the nutrients needed by the human body, increase the flavor of vegetables, and promote appetite. Common edible oils are squeezed from peanuts, corn, olives, rapeseed and other materials. They contain saturated fatty acids, unsaturated fatty acids and trace elements. Moderate consumption can supplement the nutrients needed by the human body, provide energy for activities, enhance the body's resistance, and promote appetite. However, edible oil is high in calories. Excessive consumption can lead to obesity, increase the burden on cardiovascular and cerebrovascular diseases, and increase the risk of cardiovascular and cerebrovascular diseases.

[0003] At present, the edible oils on the market have the disadvantages of single nutritional ingredients, insufficient nutritional ingredients, and unbalanced nutritional ingredients, which is in contradiction with the growing sense of gain and happiness of the Chinese people. The nutritional imbalance and lack of richness of edible oils on the market are mainly due to the single source of raw materials for the production of edible oils and simple fatty acids. In the face of brain degeneration and memory loss, the treatment mainly relies on drug treatment, such as taking appropriate drugs to nourish nerves (such as methylcobalamin, citicoline, idebenone, etc.) to improve, and then assist with a combination of work and rest, avoid staying up late and high-intensity mental activities to improve. After investigation, it has not been found that edible oil can improve memory loss and brain degeneration. According to the principle of medicine and food being of the same origin, it is urgently needed to develop an edible oil formula that improves the above-mentioned diseases from a dietary perspective.
