Problems solved by technology

[0015] Disadvantages: 1. The effect of improving the anti-oxidation period of its products is relatively poor
2. The problem of insufficient effective dispersion and stability of water-insoluble polyphenolic antioxidants in water-based systems is not mentioned in the above invention or the effect is not very satisfactory
[0016] In addition, in the prior art, the results of the preparation of polyphenolic natural antioxidant complex emulsions show that it is difficult to prepare water-based antioxidant complexes when water-insoluble polyphenolic natural antioxidants are used as raw materials , and the hidden health hazards and environmental pollution caused by the use of a large amount of organic solvents have become an important reason restricting its extensive development and application
At the same time, whether it is water-soluble or water-insoluble natural antioxidants, they are also criticized for their poor antioxidant stability and short effective period.

Abstract

The invention discloses a preparation method of a cellulose-based polyphenol antioxidant compound. The compound formula is composed of matrix raw materials, nano / micron-sized cellulose substances or their derivatives loaded with matrix raw materials, and stabilizers. , consisting of auxiliary raw materials and aqueous / organic solvent solutions, the process steps of the preparation method include preparing aqueous / a small amount of organic solvent solutions of polyphenols natural antioxidants, and preparing colloidal solutions of nano / micron-sized cellulose substances or derivatives thereof , add stabilizer to colloidal solution, or do not add stabilizer, pre-shear to obtain water-based carrier colloid emulsion with moderate viscosity, preparation of cellulose-based polyphenol antioxidant complex emulsion / particles. The invention significantly reduces the ineffective decomposition of polyphenolic natural antioxidants through the loading effect of the cellulose-based carrier, improves the effective period of antioxidants, and can make the effective time of antioxidation / free radical scavenging under the optimal dosage Extend over 300%.

Description

technical field [0001] The invention relates to a method for preparing an antioxidant compound, in particular to a method for preparing a cellulose-based polyphenol natural antioxidant compound emulsion / granule, and belongs to the technical field of natural / synthetic antioxidant preparation. Background technique [0002] The brand-new life concept of anti-aging, skin care and fat reduction, healthy diet, and keeping away from diseases has increasingly become the mainstream of today's society, and is generally pursued by people of all ages. The differentiation and aging of body cells and the spoilage of food are all considered to be related to the excessive oxidative stress response of oxygen free radicals, and antioxidants have a good ability to remove free radicals, and their use can play a good role in food preservation and human health. Anti-aging, disease-removing and other effects. [0003] According to the source, antioxidants mainly include two categories: natural an...
