Embodiment 1

[0022] This embodiment provides an oily system containing 3,4-dihydroxyphenethyl alcohol. The oily system includes: 3,4-dihydroxyphenethyl alcohol, an oily solvent and a protective agent. Wherein, the oily solvent includes: sesame oil and walnut oil; the protective agent is p-hydroxyacetophenone. In terms of parts by mass, the composition of the oily system is 1.2 parts of 3,4-dihydroxyphenethyl alcohol, 996 parts of sesame oil, 996 parts of walnut oil, and 1.5 parts of p-hydroxyacetophenone. Wherein, the concentration of the oily system containing 3,4-dihydroxyphenethyl alcohol in this embodiment is 0.6 mg / ml.

[0023] The preparation method of the oily system provided in this embodiment includes the following steps:

[0024] Step 1: Weigh 996 parts of sesame oil and 996 parts of walnut oil, stir evenly, and heat to 20°C to prepare a hot oily solution; wherein, the heating method in step 1 is preferably water bath heating. Step 2: Weigh 1.2 parts of 3,4-dihydroxyphenethyl alcoho...

Embodiment 2

[0033] The difference from the above embodiment is that the oily solvent in this embodiment includes cottonseed oil and grapeseed oil; the protective agent is phytic acid. In terms of parts by mass, the composition of the oily system is: 4.9 parts of 3,4-dihydroxyphenylethanol, 1120 parts of cottonseed oil, 830 parts of grape seed oil, and 5.2 parts of phytic acid. Wherein, the concentration of the oily system containing 3,4-dihydroxyphenethyl alcohol in this embodiment is 2.50 mg / ml.

[0034] The preparation process of the oily system in this embodiment includes the steps:

[0035] Step 1. Weigh 1120 parts of cottonseed oil and 830 parts of grapeseed oil, stir evenly, and heat to 24°C to prepare a hot oily solution. Step 2: Weigh 4.9 parts of 3,4-dihydroxyphenethyl alcohol and 5.2 parts of phytic acid respectively. Step 3. Slowly add the weighed 3,4-dihydroxyphenethyl alcohol dropwise to the hot oily solution in step 1, stir and mix evenly at constant temperature; add the weighe...

Embodiment 3

[0045] The difference from the above embodiment is that the oily solvent in this embodiment includes rapeseed oil and soybean oil; the protective agent includes vitamin E succinate and N-acetylcysteine. In terms of parts by mass, the composition of the oily system is: 27.3 parts of 3,4-dihydroxyphenylethanol, 930 parts of rapeseed oil, 420 parts of soybean oil, 5.5 parts of vitamin E succinate, and N-acetylcysteine 4.8 copies. Wherein, the concentration of the oily system containing 3,4-dihydroxyphenethyl alcohol in this embodiment is 19.67 mg / ml.

[0046] The preparation process of the oily system in this example is:

[0047] Step 1: Weigh 930 parts of rapeseed oil and 420 parts of soybean oil, stir evenly and heat to 28°C to prepare a hot oily solution. Step 2: Weigh 27.3 parts of 3,4-dihydroxyphenethyl alcohol, 5.5 parts of vitamin E succinate and 4.8 parts of N-acetylcysteine. Step 3. Add the weighed 3,4-dihydroxy phenethyl alcohol slowly to the hot oily solution in step 1, ...

Abstract

The invention relates to an oily system containing 3,4-dihydroxyphenylethanol. The oily system consists of, by mass in parts, 1.2-96 parts of the 3,4-dihydroxyphenylethanol, 145-2,290 parts of an oilysolvent and 1.5-96 parts of a protective agent. A preparation method and applications of the oily system are also provided. The oily system is formed by uniformly mixing 1.2-96 parts of the 3,4-dihydroxyphenylethanol, 1.5-96 parts of the protective agent and 145-2,290 parts of the oily solvent; the oily system has good light stability and thermal stability, so that the application products of theoily system can be avoided from discolouring due to oxidation during using; and therefore, the oily system has good applicability.

Description

Technical field [0001] The invention relates to the technical field of materials, in particular to an oily system containing 3,4-dihydroxyphenethyl alcohol, a preparation method and its application. Background technique [0002] 3,4-Dihydroxyphenylethanol is a highly active natural polyphenol compound, mainly found in olives and other plants, and has good water and fat solubility. The polyhydroxyl chemical structure of 3,4-dihydroxyphenylethanol gives it excellent biological activity. Studies have shown that its antioxidant capacity is excellent and can promote mitochondrial production. The antioxidant mechanism of 3,4-dihydroxyphenylethanol is to act as a hydrogen donor to reduce singlet oxygen to triplet oxygen with lower activity and reduce the generation of oxygen free radicals; combine with more active free radicals to become a low activity Polyphenol free radicals interrupt the free radical chain reaction; the 3-position phenolic hydroxyl group of 3,4-dihydroxyphenethyl al...
