A producing method of food-level concentrated soybean phospholipid

Abstract

A method for producing food level condensed soybean phospholipids belongs to the field of soybean phospholipids. The invention comprises: taking feedstuff level soybean phospholipids as raw material, dissolving with nonpolar solvent such as N-hexane or ligarine, decolorizing with food level H2O2, removing ethylether insoluble substance influencing the product transparence with inorganic membrane filtration technique (including inorganic ceramic membrane and stainless steel membrane), and evaporating to obtain the light-colored final product with good transparence and low ethylether insoluble substance content (less than 0.2%, while 0.3% as the abroad product index). The invention establish a complete technology for producing food level condensed soybean phospholipids with high quality with feedstuff level soybean phospholipids as raw material through discolorations, filtration and de-dissolve.

Description

technical field

[0001] The invention discloses a method for producing food-grade concentrated soybean phospholipids, which belongs to the technical field of soybean phospholipids. Background technique

[0002] Food-grade phospholipids are derived from soybeans and other plants. They are processed from the colloidal waste produced in the degumming section of soybean oil processing. It is a complex mixture of phospholipids and acetone insoluble substances. The phospholipids are mainly composed of phosphatidylcholine. (PC), phosphatidylethanolamine (PE) and phosphatidylinositol (PI), soybean phospholipids not only have the functions of softening blood vessels and protecting the liver, but also have emulsifying, wetting, and colloidal properties. In countries such as Europe and the United States, soybean phospholipids have become a very popular nutritional food. In the sales list of health care products in the United States, soybean phospholipids rank among the top three. In ad...

Embodiment 1

[0015] Feed-grade soybean concentrated phospholipids are used as raw materials and dissolved with n-hexane. The mass ratio of raw materials and solvents is optimal for the raw material dissolution process. During the decolorization process, hydrogen peroxide with 1.5% of the feed-grade soybean concentrated phospholipid mass is added and stirred at 40°C for decolorization. For 40 minutes, choose 200nm membrane tube, the temperature is 35 ℃, the filter treatment effect is best under the pressure before the tube 0.15MPa, the primary evaporation condition is 60 ℃, the residual pressure is 0.18kPa, the secondary evaporation temperature is 75 ℃, the residual pressure 0.18kPa, the acetone insoluble matter of the obtained product is greater than 62%, the ether insoluble matter is less than 0.2%, the Gardner color is 11+, the volatile matter is less than 50mg / kg, and the product has good transparency.

Embodiment 2

[0017] Feed-grade soybean concentrated phospholipids are used as raw materials and dissolved in petroleum ether. The mass ratio of raw materials and solvents is 1:2 in the raw material dissolution process. During the decolorization process, hydrogen peroxide with 1% of the feed-grade soybean concentrated phospholipid mass is added, and stirred at 60 ° C for 20 minutes to decolorize , select 50nm membrane tube, filter at 50°C and 0.3MPa in front of the tube, the primary evaporation condition is 50°C, the residual pressure is 0.18kPa, the secondary evaporation temperature is 60°C, and the residual pressure is 0.18kPa, the product is obtained The acetone insoluble matter is greater than 62%, the ether insoluble matter is less than 0.2%, the Gardner color is 11+, the volatile matter is less than 50mg / kg, and the product has good transparency.

[0019] Feed-grade soybean concentrated phospholipids are used as raw materials and dissolved with n-hexane. The mass ratio of raw materials and solvents used in the raw material dissolution process is 1:6. During the decolorization process, 4% hydrogen peroxide is added to feed-grade soybean concentrated phospholipids, and stirred at 20 ° C for 60 minutes. , using a 500nm membrane tube, the temperature is 20°C, the pressure before the tube is 0.05MPa, and the filtration treatment is carried out. The primary evaporation condition is 70°C, the residual pressure is 0.18kPa, the secondary evaporation temperature is 90°C, and the residual pressure is 0.18kPa. The product is obtained The acetone insoluble matter is greater than 62%, the ether insoluble matter is less than 0.2%, the Gardner color is 11+, the volatile matter is less than 50mg / kg, and the product has good transparency.
