Vegetable fats contain more unsaturated fatty acids, especially linolenic acid, which not only has the effect of strengthening one's health, but also has a nice glamorous skin effect. It is an indispensable nutrient for the skin to moisturize and fill. In addition, linolenic acid is also rich in vitamin E and other nutritional skin and anti-aging ingredients. Not only has the effect of beauty and beauty, but also has the function of health and anti-aging.
The linolenic acid-rich foods include safflower oil, sunflower oil, soybean oil, maize oil, sesame oil, peanut oil, tea oil, rapeseed oil, sunflower seeds, walnuts, pine nuts, almonds, and peach kernels. Linoleic acid.
Ideal food or health products
In normal foods, the content of alpha-linolenic acid is minimal. Only a few foods such as flaxseed, perilla seed, hemp seed, walnut, cocoon, and deep-sea fish contain abundant α-linolenic acid and its derivatives. The most ideal foods or health foods rich in α-linolenic acid are: Perilla seed oil, linseed oil (also called flax oil), and α-linolenic acid capsules. The use of blended oil containing α-linolenic acid in daily life is a very good choice.
Terrestrial plants
Alpha-linolenic acid in terrestrial plants is mainly found in walnuts, flaxseed oil, and perilla oil. Others such as soybean oil, hempseed oil, perilla oil, wheat germ oil, and canola oil are generally comparable in content. low. Traditionally, for example, soybean oil contains linolenic acid (5% to 9%), which makes it easy to relish or oxidize, thus limiting its use. Soybean oil is a semi-dry oil, so it is widely used in dry oil-based products. The purpose of improving soybeans is generally to reduce the content of linolenic acid. People tried to reduce the content of linolenic acid by methods such as variety improvement, extraction and reaction removal. The method of hydrogenation was relatively successful.
Rubber is a high elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under the action of a small external force. It can recover its original state after the removal of external force. Rubber is a completely amorphous polymer with a low glass transition temperature (T G) and a high molecular weight of more than several hundred thousand.
Rubber is divided into natural rubber and synthetic rubber two kinds. Natural rubber is made from rubber tree, rubber grass and other plants after extraction and processing. Synthetic rubber is made by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.
