Problems solved by technology

However, the above-mentioned method for preparing lignin nanoparticles by dissolving in a low co-solvent has many types of solvents and high concentration requirements, and the preparation steps are relatively complicated, so it is not suitable for large-scale promotion and utilization.
At the same time, the appearance of lignin nanoparticles prepared by the currently disclosed method is an amorphous structure, and it is difficult to prepare spherical lignin nanoparticles
After searching, there is no report about the method and product of using grape seed to prepare functional grape seed nanosphere particles

Abstract

The invention discloses a method for preparing functional grape seed nanosphere particles by using grape seeds, the method comprises the following steps: crushing grape seeds in residues after wine brewing, firstly extracting grape seed oil by petroleum ether-ultrasonic assistance through process optimization, then extracting procyanidine in the grape seeds by using ethanol, dissolving the grape seed lignin in a tetrahydrofuran aqueous solution (the normal temperature is about 25 DEG C, and heating is not needed), performing rotary evaporation precipitation and washing, and then preparing grape seed nanosphere particles with excellent morphology and high added value. The method is easy to operate and low in cost, the application value of the grape seed residues is effectively improved, all-component utilization of the grape seed residues is achieved, and the prepared nanosphere particles have high ultraviolet absorption capacity and certain oxidation-reduction capacity and are suitable for large-scale production. The nanosphere particles can be used as an efficient and natural raw material and have a huge application prospect in preparation of anti-ultraviolet coatings or protective articles and preparation of cosmetics and drug carriers.

Description

technical field [0001] The invention relates to a method for nanosphere particles, in particular to a method for preparing functional grape seed nanosphere particles using grape seeds and a product thereof, belonging to the technical field of nanomaterial preparation. Background technique [0002] The cultivated area of ​​grapes in my country reaches 12 million mu, accounting for 6.2% of the world's total, ranking fifth in the world, of which the cultivated area of ​​wine grapes reaches 2 million mu, ranking second in the world. my country's wine industry produces hundreds of thousands of tons of grape seed residue every year. How to efficiently utilize grape seed residue as a waste of the grape deep processing industry has become an urgent problem to be solved. Vigorously developing and comprehensively utilizing grape seed residues can not only alleviate environmental pressure, but also bring substantial economic benefits to production enterprises.
