Lignin, Fibres, Ligninase


Lignin is a natural polymer substance with a phenolic structure, widely present in woody plants, herbs, vascular plants, is the second largest natural polymer material in nature after cellulose in quantity, and is the only aromatic compound that can be obtained from renewable resources in industry. Lignin is widely used in building materials industry, petroleum industry, light industry, and agriculture. Lignin is also an important part of human dietary fibres (DF), which can change the activity of microorganisms in the intestinal system, reduce the content of cholesterol and blood sugar in the blood, and have the effect of preventing cardiovascular disease; Lignin also has antioxidant activity and inhibition of cancer cell activity. As a natural antioxidant active substance, the anti-free radical activity of lignin in wood and crop straw has been extensively studied, while lignin in dietary fiber such as vegetables and fruits has not been studied much Extracting lignin from carrots and studying its structure and antioxidant activity is expected to obtain a natural, non-toxic side effect antioxidant active substance, which has a wide application prospect in the food industry, cosmetics, health products and other aspects.
