4 results about "Pine nut oil" patented technology

This invention belongs to the field of plant oil extraction technology, specifically relating to a method for preparing pine nut oil rich in pinolenic acid and its preparation. The method for preparing pine nut oil rich in pinolenic acid provided by this invention mainly includes the following steps: gas spraying, centrifugal oil separation, high-solids enzymatic hydrolysis, freeze-thaw reaction, saponification reaction, and urea inclusion. The beneficial effects of this invention are that by using a mixed gas for rapid slurry modification of pine nuts, combined with stepwise enzymatic hydrolysis and freeze-thaw processes, not only is the extraction rate of pine nut oil improved, but it also helps to protect components such as pinolenic acid in the pine nut oil from damage. Results show that the extraction rate of highly unsaturated pine nut oil obtained by the method of this invention is >85%, and the pinolenic acid content in the unsaturated fatty acids of the pine nut oil rich in pinolenic acid is >70%. Furthermore, the obtained pine nut oil unsaturated fatty acids exhibit good lipid-lowering effects.

The invention relates to the technical field of personal care products, in particular to a composite cleaning, deodorizing and antioxidant care wet tissue for old people and a preparation method thereof.The composite cleaning, deodorizing and antioxidant care wet tissue comprises a base material and a care solution loaded on the base material, and raw materials of the care solution comprise a cleaning component, a deodorizing component, a skin care and moisturizing component, an antioxidant component, an anti-corrosion component and a solvent; the odor removing component is any one of cyclodextrin and tromethamine or a combination of the cyclodextrin and the tromethamine; the antioxidant component is any one of pine nut oil and tocopherol or a combination of pine nut oil and tocopherol. The invention has the advantages that the compound system of cyclodextrin and tromethamine is used for targeted embedding and neutralizing the key molecule 2-nonenal of senile taste; a compound system of pine nut oil and tocopherol is used for synergistically scavenging free radicals and inhibiting peculiar smell caused by sebum decomposition. That is to say, the wet tissue disclosed by the invention integrates the functions of cleaning, odor removal, skin care and oxidation resistance, provides mild, efficient and lasting comprehensive care for the skin of the old people through the synergistic effect of all the components, and solves the problems of single function and incomplete care of the existing product.

This invention relates to a self-assembling reverse micelle transparent oily composition, its preparation method, and its application. The oily composition comprises the following components in parts by weight: 12-28% oil-soluble reverse micelle inclusions and 0.1-0.5% natural oil composition, with the balance being caprylic / capric triglycerides and 1,2-hexanediol in a mass ratio of (0.9-1.2):1. The oil-soluble reverse micelle inclusions are a composition of *Candida beeinae* / glucose / rapeseed oleate fermentation product and macadamia seed oil, and the natural oil composition is a composition of pine nut oil, *Inca inchi* seed oil, and burdock seed oil. This invention overcomes the technical defects of traditional repairing oily compositions, such as the need for emulsifiers, easy turbidity and layering, sticky feel, and poor stability. It achieves stable loading of aqueous components in a fully oil-based formulation without adding emulsifiers and volatile oils, resulting in a completely transparent, clear, and long-term stable essential oil appearance.
