Problems solved by technology

The pressing method has a low oil yield and high work intensity, while the solvent extraction method consumes a lot of solvent, it is difficult to recover the solvent, and there are prominent problems such as flammability and explosion.
Not only the extraction method is cumbersome and the extraction efficiency is low, but the extracted rice bran oil is not suitable for use in cosmetics

Embodiment 1

[0031] The extraction of embodiment 1 rice bran oil and condition optimization

[0032] Weigh 200g (accurate to 0.01g) of 60-mesh rice bran with an electronic balance, put the rice bran into the barrel, put the barrel into the extraction kettle, install the pressure ring and sealing ring, tighten the plug, and start the supercritical extractor , set the flow rate of carbon dioxide to 20L / h, and investigate the influence of pressure, temperature and extraction time on supercritical CO2 extraction. The extraction efficiency is evaluated based on the quality of rice bran oil extracted from 200g of rice bran (accurate to 0.01g).

Embodiment 11

[0033] The optimization of embodiment 1.1 extraction pressure

[0034]The flow rate of fixed carbon dioxide is 20L / h, the extraction temperature is 40°C, and the extraction time is 2 hours. The influence of extraction pressure on extraction efficiency is shown in Table 1 below:

[0035] The influence of table 1 extraction pressure on extraction efficiency

[0036] Extraction pressure / MPa 20 25 30 35 40 Mass of rice bran oil / g 28.11 34.15 38.87 38.92 39.01

[0037] It can be seen from Table 1 that the extraction amount of rice bran oil gradually increases with the increase of extraction pressure. The optimal extraction pressure is 30-40Mpa. When the extraction pressure was 30MPa, the extraction of rice bran oil did not increase significantly when the extraction pressure was increased. Considering comprehensively, the optimal extraction pressure is 30MPa.

Embodiment 12

[0038] The optimization of embodiment 1.2 extraction temperature

[0039] The flow rate of fixed carbon dioxide is 20L / h, the extraction pressure is 30MPa, and the extraction time is 2 hours. The influence of extraction temperature on extraction efficiency is shown in Table 2 below:

[0040] The influence of table 2 extraction temperature on extraction efficiency

[0041] Extraction temperature / ℃ 25 30 35 40 45 Mass of rice bran oil / g 27.63 31.05 35.22 38.87 33.52

[0042] It can be seen from Table 2 that the extraction temperature has a great influence on the extraction amount of rice bran oil, the optimum extraction temperature is 35-45°C, and the optimum extraction temperature is 40°C.

Abstract

The invention provides a method for extracting rice bran oil, which uses rice bran as a raw material and uses a supercritical CO2 extraction technology for extraction, and does not use an entrainer in the extraction. The present invention further provides the rice bran oil obtained by the extraction method of the present invention, and a cosmetic composition comprising the rice bran oil. The rice bran cosmetic composition of the present invention has excellent repairing, whitening and moisturizing effects, and is especially suitable for people with sensitive skin and damaged skin keratin barrier.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a method for extracting rice bran oil, the rice bran oil obtained by the extraction method, and a cosmetic composition containing the rice bran oil. Background technique [0002] Rice bran is the main by-product in rice processing, accounting for about 7% of the weight of rice. At present, the annual output of rice bran in my country is about 14 million tons. About 60% of the physiologically active ingredients in rice grains are concentrated in rice bran, which is rich in rice bran oil, phytic acid, inositol, etc. Wherein the rice bran oil contains 3-10% of gamma-oryzanol, 0.3-0.5% of vitamin E, 3-11% of rice bran sterol, and 0.3-5% of squalene. [0003] Rice bran oil and the γ-oryzanol, vitamin E, rice bran sterol, and squalene rich in rice bran oil are excellent nutritional repair ingredients for the skin, with emollient, anti-inflammatory, repairing, and anti-oxidative effects. γ-Or...
