Problems solved by technology

In other words, the previous technology did not focus on carbon dioxide as a solvent, and selected a step in the process to explore its operation, so the obtained sesame lignin concentration still needs to be improved

Embodiment Construction

[0033] The content, characteristics and embodiments of the invention are explained below with the help of drawings, so that your examiner can have a better understanding of this case. The following are the preferred embodiments proposed in the foregoing description:

[0034] Please refer to the schematic diagram of the process equipment in Fig. 1, the present invention is illustrated in a preferred embodiment:

[0035] The main technical means are:

[0036] 1. Pump the sesame oil containing low concentration of sesamin into the extraction tower E1.

[0037] 2. Pump carbon dioxide with a temperature lower than 35°C (the temperature is obtained from the experiments in Table 1 and Table 2) from the washing section E11 into the extraction tower E1, and contact with the sesame oil in the tower to extract the sesame oil The sesamin in the medium, and the low-concentration sesame oil is discharged outside the tower of the extraction tower E1 and becomes the raffinate product at the...

Abstract

The present invention relates to sesamin concentrating and purifying process. In the process, low concentration sesamin oil is concentrated and extracted with CO2 at the temperature lower than 35 deg.c and in liquid state or gaseous state to obtain high concentration sesamin oil. After low concentration sesamin oil led into the extracting space, CO2 at the temperature lower than 35 deg.c is introduced and most of sesamin flows with CO2, so as to reach the concentration aim.

Description

technical field [0001] The invention relates to a method for concentrating and purifying sesamin, in particular to the technology of using carbon dioxide as a solvent to conduct semi-continuous or continuous liquid-liquid or vapor-liquid extraction to extract and concentrate sesamin. Background technique [0002] Sesame is rich in lipids, protein, calcium, iron and vitamins. It can be said to be a food with health and beauty effects. Sesame lipid contains about 1% of sesame lignan (Lignan), which is a mysterious ingredient that has attracted special attention. Sesame lignin can be subdivided into six types: Sesamin, Sesamol, Sesaminol, Sesamolin, Pinoresinol, and Sesamolinol. These ingredients are also antioxidant substances that have a preventive effect on the "active oxygen" in the body that can cause human aging and adult diseases. Sesame was first eaten 100 years ago, but its physiological activity has not been investigated and understood in detail until the past decad...
