At present, edible oil is only used as life seasoning. Is there a kind of edible oil that can be seasoned and has health care functions?

Yes, there is! It is Acer truncatum.

Acer truncatum is an excellent tree species for greening

Acer truncatum, a deciduous tree, 8-10m high. Flowering in May and fruiting in September. Acer truncatum is named after its samari shape resembles the ancient Chinese "gold ingot ingot".

Acer truncatum oil is an excellent woody edible oil

Acer truncatum is a new resource of high-quality edible vegetable oil, with large seeds and high oil content. The oil content of the seed kernel of Acer truncatum is 48%, and the oil output rate of the machine is 35%, which is higher than the oil output rate of rapeseed. Acer truncatum oil is a semi-drying oil mainly containing oleic acid and linoleic acid. It has a high content of essential fatty acids and excellent oil quality. Among them, the essential fatty acids-linoleic acid and linolenic acid are as high as 53%, which is better than vegetable oil and is rare in edible vegetable oil.

On March 22, 2011, the Ministry of Health of the People's Republic of China officially issued an announcement approving Acer truncatum seed oil as a new resource food. Acer truncatum seed oil contains nervonic acid, which is recognized by scientists around the world as the only dual-effect miraculous substance that can repair nerve fibers in damaged brain nerve pathways and promote nerve cell regeneration. Its deficiency will cause brain diseases such as stroke sequelae, senile dementia, cerebral palsy, brain atrophy, memory loss, insomnia and forgetfulness.

Acer truncatum is a new resource of high-quality protein

The seed kernel contains 25%-27% protein and does not contain starch, which is rare in plant seeds. After the seeds are extracted from the oil, the oil meal is a good edible protein. According to measurement, the protein in the seed kernels of Acer truncatum contains 8 kinds of essential amino acids, which is a complete protein and is an ideal new resource of plant protein.

This kind of tree species that integrates multiple benefits will become a new species of high-efficiency agriculture in my country, and become a leader in ecological economic agriculture.
