Description

Composition rich in zeaxanthin and almond oil and application thereof
Technical Field
The invention relates to the technical field of almond oil production, in particular to a composition rich in zeaxanthin and almond oil and application thereof.
Background
With the coming of the digital era, electronic products gradually permeate into the lives of people, mobile phones, computers and the like become necessities for life, but the electronic products bring convenience and bring a substance of 'blue light'. Blue light is light with higher energy at a wavelength between 400nm and 480nm, is part of a visible spectrum, and has stronger penetrating power than ultraviolet rays. The combination of short-wave blue light and yellow luminous bodies enables an LED (light emitting diode) to generate white light, the use frequency of the LED is exponentially increased in recent years, and the LED is increasingly applied to the fields of low-energy bulbs, computers, mobile phones and the like, so that the time of receiving blue light irradiation by people is greatly prolonged. Blue light can penetrate the dermis of the skin and has phototoxicity, so that the fiber cells in the dermis are damaged, the extracellular matrix is reduced, and the skin is aged prematurely. The skin can generate oxidative stress after receiving blue light irradiation, and high-activity oxygen free radicals are generated in mitochondria to cause oxidative damage of cells; blue light also causes a decrease in skin cell activity to reduce the self-healing power of the skin, and inhibits the secretion of melatonin, resulting in insomnia.
Zeaxanthin is used as a fat-soluble carotenoid, the absorption spectrum of the zeaxanthin is between 446-450nm, the zeaxanthin can absorb blue light and has the effect of resisting blue light damage, and the carotenoid of the same kind, such as lutein, can also absorb blue light and has the synergistic effect of zeaxanthin to resist blue light. Meanwhile, the zeaxanthin also has strong antioxidation, 11 conjugated double bonds are arranged in a molecular structure, and a hydroxyl group is arranged at the tail end, so that the structure determines the antioxidation activity of the zeaxanthin, and the singlet oxygen is quenched to protect a photosensitive cell layer caused by active oxygen from being damaged by light. However, the double bond structure makes the chemical property of the product very unstable, and the degradation or isomerization of the zeaxanthin is easily caused by illumination, oxygen, temperature and the like, so that the product produced by taking the zeaxanthin as the raw material has fewer varieties, and the property of insolubility in water also limits the application of the product. The almond oil is the most mild accepted vegetable oil, contains rich substances such as unsaturated fatty acid, mineral substances, protein, vitamin and the like, has high vitamin E content, and can effectively resist free radicals, inhibit the generation of lipid peroxide and remove chloasma. The almond oil can provide nutrient substances absorbed by the skin, can reduce the water loss of the skin, nourish the skin, eliminate skin surface inflammation and accelerate the regeneration of skin cells, and is a good skin protection humectant. However, unsaturated fatty acid components are easily oxidized, which is also a main cause of short shelf life of the grease.
Zeaxanthin is used as a substance with a remarkable blue light resistance effect, is usually prepared into a sealing substance such as a capsule due to the unstable property of the zeaxanthin, and the zeaxanthin is cooperated with lutein to act on the macular degeneration of the eyes, and the zeaxanthin is usually used as a main effective component, and functional components are taken to reach the retina or other tissues through the blood circulation of a human body to exert the effect, so that the needed time is long, the zeaxanthin is low in dosage, certain loss is generated through the circulation, the dosage reaching the action site is less, and the zeaxanthin can effectively exert the effect only by being regularly taken for a long time. The oral carotenoid is not high in efficiency, the protective effect on skin can be effectively improved through external application, for example, a patent with application number 202010743429.5 discloses a repair skin cream with a blue light resisting function and a preparation method thereof, the blue light resisting auxiliary agent is prepared by compounding pretreated lutein and silanediol salicylate, and the obtained repair skin cream has a good blue light resisting effect. But the existing external blue-light resistant products taking zeaxanthin as a main component are few; the existing skin care oil mostly takes white oil as base oil, is not easy to be absorbed by skin, and most products achieve certain efficacy by adding chemical components, have irritation to skin, are not widely applicable to people, and consumers are more and more pursuing natural, green and natural products.

As can be seen from tables 1 to 5, the oxidation degree of the composition is lower than that of the composition in the comparative example and pure almond oil under the same storage condition, because zeaxanthin has conjugated unsaturated double bonds, can provide hydrogen atoms and electrons, has strong ability of absorbing free radicals, and can inhibit lipid peroxidation so as to delay oxidative deterioration of oil. Meanwhile, compared with other types of oil, the almond oil has stronger protection effect on the zeaxanthin, and the rich vitamin E, mineral substances, protein and other components can effectively inhibit the degradation or isomerization of the zeaxanthin, so that the bioactive action time of the composition is longer, and the skin is protected for a longer time. The results in the table also show that the composition needs to be stored in a cool and dry place in a sealing way when being used daily, so that the phenomenon that the service life is shortened due to accelerated oxidation of light, moisture and the like is avoided.
