Embodiment 1

[0024] The perilla oil refining method of the present invention uses perilla crude oil as a raw material and is prepared through the following steps:

[0025] (1) Degumming: Add 10% of the total weight of water, heat to 50-60°C for 10-20 minutes, stir, and centrifuge; then add 5% of the total mass of acetic acid with a total mass concentration of 0.1%. and phosphoric acid solution, heated to 40-50°C, stirred for 10-20min, and centrifuged;

[0026] (2) Deacidification: add 0.4% sodium bicarbonate of total mass, stir, and centrifuge;

[0027] (3) Dehydration: use vacuum decompression to dehydrate, and the temperature is controlled below 60°C;

[0028] (4) Decolorization: Add bentonite and activated carbon with a total mass of 2%, at a temperature of 40 to 50° C., and stir for 20 minutes, wherein the mass ratio of bentonite and activated carbon is 1:10;

[0029] (5) Filtrate and obtain perilla oil product oil.

Embodiment 2

[0031] The perilla oil refining method of the present invention uses perilla crude oil as a raw material and is prepared through the following steps:

[0032] (1) Degumming: Add 12% of the total weight of water, heat to 40-50°C for 10-20 minutes, stir, and centrifuge; then add 2% of the total mass of acetic acid with a total mass concentration of 0.1% and phosphoric acid solution, heated to 40-50°C, stirred for 10-20min, and centrifuged;

[0033] (2) Deacidification: add 0.3% sodium hydroxide of the total mass, stir, and centrifuge;

[0034] (3) Dehydration: use vacuum decompression to dehydrate, and the temperature is controlled below 60°C;

[0035] (4) Decolorization: Add 0.5% of the total mass of activated carbon, the temperature is 40-50 ° C, and stir for 30 minutes;

[0036] (5) Filtrate to obtain perilla oil product oil.

Embodiment 3

[0038] The perilla oil refining method of the present invention uses perilla crude oil as a raw material and is prepared through the following steps:

[0039] (1) Degumming: Add 8% of the total weight of water, heat to 45-55°C for 15 minutes, stir, and centrifuge; then add 4% of the total mass concentration of 0.1% equal mass of acetic acid and phosphoric acid solution, heated to 40-45°C, stirred for 20 minutes, and centrifuged;

[0040] (2) deacidification: add 1.4% sodium carbonate of gross mass, stir, and centrifuge;

[0041] (3) Dehydration: use vacuum decompression to dehydrate, and the temperature is controlled below 60°C;

[0042] (4) Decolorization: Add bentonite and activated carbon with a total mass of 1%, at a temperature of 40 to 50°C, and stir for 20 minutes, wherein the mass ratio of bentonite and activated carbon is 1:5;

[0043] (5) Filtrate and obtain perilla oil product oil.

Abstract

The invention provides a perilla oil refining method. Perilla oil is prepared by the steps of by taking perilla crude oil as raw material, degumming, deacidification, dehydration, decoloration and filtration. By virtue of the perilla oil refining method, the loss of neutral fatty acid is little; and the produced perilla oil has the advantages of high oil quality, few impurities and the like.

Description

technical field [0001] The invention belongs to the field of edible oil processing, and in particular relates to a method for refining and preparing perilla oil. Background technique [0002] Perilla, scientific name: Perilla frutescens (L.) Britt., aliases: Guiren, Baisu, Chisu, etc.; it is an annual herb of Lamiaceae. In my country, it is mainly distributed in Hubei, Shaanxi, Zhejiang, Jiangsu, Liaoning, Taiwan and Fujian provinces. Perilla is a traditional medicinal and edible plant, and it is one of the first batch of 60 items that are both food and medicine promulgated by the Ministry of Health. [0003] Perilla oil is obtained from the mature seeds of perilla, a medicinal plant of the Labiatae family. It is a highly unsaturated natural oil, and its main component is α-linolenic acid, with a content as high as 50%-70%. It has the highest content of this fatty acid among all natural vegetable oils found so far. It also contains 18 kinds of amino acids and a variety of...
