Embodiment Construction

[0019] A membrane extraction process of soybean lecithin according to the present invention comprises the following steps:

[0020] Step 1: Select plump raw soybeans, clean them, and remove shriveled and inferior soybeans;

[0021] Step 2, impurity removal ultrafiltration membrane, put the cleaned plump soybeans into the ultrafiltration membrane for impurity removal;

[0022] Step 3, ultrafiltration membrane extraction, continue to put the impurity-removed soybeans into the ultrafiltration membrane, carry out sterilization, and extract soybean lecithin;

[0023] Step 4, concentrate the nanofiltration membrane, put the soybean lecithin extracted in the step 3 into the nanofiltration membrane, decolorize and concentrate;

[0024] Step five, the finished product is packaged and put into storage.

[0025] In the first step, soybeans are used as the raw material for soybean lecithin extraction. When selecting soybeans, attention should be paid to selecting soybeans with full grai...

Abstract

The invention discloses a membrane-method extraction process for soybean lecithin. The process comprises five steps, i.e., (1) picking full-grained raw material soybeans, and cleanly washing the soybeans; (2) carrying out ultrafiltration-membrane impurity removal; (3) carrying out ultrafiltration-membrane extraction; (4) carrying out nanofiltration-membrane concentration; and (5) thereby obtaining a finished product. According to the process, the separation and purification of macromolecular and micromolecular substances at a normal temperature are achieved through membrane-method production, and the traditional processes such as extraction and decolorization are replaced, so that on one hand, the efficiency of use of membrane equipment is increased, on the other hand, an ultrafiltration system can achieve continuous charging and continuous concentrated discharging, and thus, the quality and yield of the product are improved.

Description

technical field [0001] The invention relates to a soybean lecithin extraction process, in particular to a membrane method extraction process of soybean lecithin. Background technique [0002] Soy lecithin is the essence of soybean, known as the "third nutrient" alongside protein and vitamins. Soybean lecithin is a basic substance of life. It is not only an important part of the human biofilm, but also a source of choline and fatty acids. It plays a key role in maintaining the physiological activity of the biofilm and the normal metabolism of the body. Known as "blood vessel scavenger", lecithin is a comprehensive nutrient, often supplemented, it is very important for preventing and improving cardiovascular and cerebrovascular diseases, strengthening the brain, preventing fatty liver and cirrhosis, and beautifying the skin. effect. When the lecithin in the human body is sufficient, it means that the body's metabolism, immunity and vitality are abundant. [0003] Lecithin i...
