Abstract

The invention relates to the field of daily chemical, in particular to a preparation method of a rosa canina fruit extract and application thereof in a skin care cream. The preparation method mainly comprises the steps that 1, dried rosa canina fruits are subjected to superfine grinding so as to pass through a 100-mesh sieve; 2, a composite biological enzyme is prepared; 3, the ground rosa canina fruits are added into a solvent, then the temperature is increased to 50-55 DEG C, then the composite biological enzyme is added, the pH is adjusted by acid to be 4.5-5.0, after the mixture is stirred to be uniform, enzymolysis is kept for 2 H at the temperature of 50-55 DEG C, then the temperature is rapidly increased to 100 DEG C for rapid inactivation, the temperature is decreased to 80 DEG C 1 MIN after inactivation, and reflux extraction is carried out for 1H; 4, the extract is filtered, deslagged, concentrated and dried to obtain an educt. The method has the advantages of being high in catalysis efficiency, mild in catalysis condition, and capable of lowering energy consumption, reducing pollution and simplifying technological procedures. When the rosa canina fruit extract prepared through the preparation method is applied to the skin care cream, the effects of well moistening, moisturizing and repairing skin can be achieved.

Description

technical field [0001] The invention relates to the field of extraction of natural products, in particular to a preparation method of Rosa canida extract and its application in skin care cream. Background technique [0002] Canine rosehip, also known as rosehip, is one of many roses or rose plants. Rosehip contains flax and oleic acid, which are extremely important for skin health. Unsaturated linolenic acid and linoleic acid can combine with protein and cholesterol to form a living membrane that gathers with the cell membrane, making the skin rapidly granulated and regenerated. [0003] The content of vitamin C in rose hips is very high. It has been detected that the VC content in the edible part per 100 grams of fresh fruit is more than 6810 mg, up to 8300 mg, ranking first among all vegetables and fruits. "King of VC", due to its high content of vitamin C, also respects its wide application in the beauty industry. The essence extracted from Rosa canidae can promote the ...
