EXTRACTION AND PURIFICATION OF NATURAL FERULATE AND COUMARATE FROM BIOMASS
20220234981 · 2022-07-28 ·

A process for a reactive extraction and subsequent purification of organic molecules from biomass comprises extracting one or more products from the biomass using an extraction solvent to solvate the products, contacting the biomass with a reactant during the extracting, recovering the one or more products, performing ultrafiltration to remove impurities from the one or more products to produce a filtered extract, extracting oils in the filtered extract using adsorption to produce a de-oiled extract, performing transesterification or hydrolysis on the de-oiled extract, and performing adsorptive purification on the ferulic acid, coumaric acid, ferulate, coumarate, or a combination thereof. The one or more products comprise extracted organic molecules comprising a ferulate or a coumarate, and the one or more products are separated from the biomass as a liquid extract.

Enzymatic method for preparation of lecithin polyunsaturated fatty acids (PUFAs)

The disclosure discloses an enzymatic method for preparation of lecithin polyunsaturated fatty acids (PUFAs), and belongs to the technical field of separation and application of enzyme. A heat treatment procedure is added after a reaction substrate is in contact with an enzyme to adjust the ratio of sn-1 lysophospholipid PUFAs to sn-2 lysophospholipid PUFAs in a reaction product and to promote the production of sn-2 lysophospholipid PUFAs, thereby promoting the production of lecithin PUFAs, which greatly increases the production efficiency of lecithin PUFAs and the lecithin PUFA content in the product. With simple operations and high reaction rate, the method can significantly increase the content of lecithin PUFAs in the product, can effectively avoid the oxidation of PUFA, and has high economic benefits and promising industrial application prospects.
