Embodiment 1

[0015] The first step: Saponification: Add 100 grams of perilla oil and 50 grams of deionized water into the container, stir and heat, control the reaction temperature at 40°C, slowly add 5% ionic membrane alkali, when the pH value of the material is greater than 12 When the PH value of the material is less than 10, slowly add the ionic membrane alkali. When the pH value of the material is maintained at greater than 10 and remains unchanged for 2 hours, the reaction ends, and the whole process is protected by nitrogen gas.

[0016] The second step: neutralization: add 450 grams of the material obtained in the first step and 900 grams of deionized water into the container and stir to obtain a milky white solution. Slowly add 30% sulfuric acid to neutralize the milky white solution to a pH of 7. After the reaction is over, this process Nitrogen protection throughout,

Embodiment 2

[0023] The first step: saponification: add 100 grams of perilla oil and 400 grams of deionized water into the container, stir and heat, control the reaction temperature at 90 ° C, slowly add 30% ion-exchange membrane alkali, and stop when the pH value of the material is greater than 12 Add ionic membrane alkali, when the pH value of the material is less than 10, slowly add the ionic membrane alkali, when the pH value of the material is greater than 10 and keep unchanged for 2 hours, the reaction ends, and the whole process is protected by nitrogen gas.

[0024] The second step: neutralization: add 600 grams of the material obtained in the first step and 6000 grams of deionized water into the container and stir to obtain a milky white solution. Slowly add 90% sulfuric acid to neutralize the milky white solution to a pH of 7. After the reaction is over, this process Nitrogen protection throughout,

Embodiment 3

[0031] The first step: Saponification: Add 100 grams of perilla oil and 100 grams of deionized water into the container, stir and heat, control the reaction temperature at 80°C, slowly add 20% ion-exchange membrane alkali, and stop adding when the pH value of the material is greater than 12 Ionic membrane alkali, when the pH value of the material is less than 10, slowly add the ion membrane alkali, when the pH value of the material is maintained at greater than 10 and remains unchanged for 2 hours, the reaction ends, and the whole process is protected by nitrogen gas.

[0032] The second step: neutralization: add 280 grams of the material obtained in the first step and 1000 grams of deionized water into the container and stir continuously to obtain a milky white solution, slowly add 70% sulfuric acid to neutralize the milky white solution to a pH of 7, and the reaction ends. Nitrogen protection is used throughout the process,

Abstract

The invention relates to a process for preparing alpha-calcium linolenate by using perilla oil as the raw material, which comprises the steps of saponifying, neutralizing, double decomposition, stewing, scouring, dewatering and drying, the content of alpha-linolenic acid in the the obtained alpha-calcium linolenate is higher than 55%, and the content of calcium is higher than 3.5%.

Description

technical field [0001] The invention relates to a method for preparing calcium α-linolenate by using perilla oil as raw material. Background technique [0002] α-linolenic acid mainly exists in a variety of vegetable oils in the form of triglycerides, including linseed oil, perilla seed oil, rapeseed oil, cottonseed oil, soybean oil, etc., among which the content of linseed oil and perilla seed oil As high as 50% to 60%, and the content in other oils is below 10%. The population is seriously deficient in unsaturated fatty acids, especially α-linolenic acid, which needs to be supplemented from other sources. It is mostly used as an additive in the medicine and food industries, and the general lack of calcium in the population can combine α-linolenic acid and calcium, so that the population can better supplement the lack of α-linolenic acid and calcium, and α-linolenic acid has not yet been invented in China. Calcium acid preparation method. Contents of the invention [0...
