47 results about "Plant stanol ester" patented technology

Stanol esters are a heterogeneous group of phytosterol esters with a saturated sterol ring structure known to reduce the level of low-density lipoprotein cholesterol in blood when ingested. Despite a well documented cholesterol lowering effect, no evidence of any beneficial effect on cardiovascular disease or overall mortality exists and a meta-analysis published in 2012 suggests that there is no effect. They are used in food products such as Benecol.

Enzymatic synthesis method of phytosterol ester/phytostanol ester by utilizing ultrasonic enhancement

The invention relates to a preparation method of sterol ester and in particular relates to an enzymatic synthesis method of phytosterol ester / phytostanol ester by utilizing ultrasonic enhancement. The method is characterized by comprising the following steps: 1) preparing a heterogeneous enzyme reaction system: weighing the phytosterol ester / phytostanol ester and fatty acid at a molar ratio of 1:(1.2-2), adding a reaction solvent, and adding enzyme and a molecular sieve; 2) performing enzymatic esterification with ultrasonic assistance: immersing an ultrasonic probe in a reaction solution, opening an ultrasonic wave generator, constantly radiating with ultrasonic wave for 0.5 to 3 hours under mechanical stirring, and continuously reacting for 4 to 10 hours under mechanical stirring after the radiation is completed; and 3) removing the fatty acid with ultrasonic assisted saponification to obtain the product. According to the method, the enzymatic esterification reaction time can be remarkably shortened, the usage of enzyme can be reduced, and the saponification speed of excessive fatty acid can be accelerated, so that the efficiency of separation and purification can be improved, and the obtained phytosterol ester / phytostanol ester product has the characteristics of light color, high purity and safety without contamination.

Method for preparing phytostanol ester under solvent-free condition

InactiveCN103122020ASuitable for food industry productionSimple processSteroids preparationInfraredChemical industry
The invention relates to a method for preparing phytostanol ester under the solvent-free condition and belongs to the technical fields of food, medicine, chemical industry and cosmetics. According to the technical scheme, the method comprises the following steps of: adding fatty acid or aromatic acid, phytostanol and a catalyst at a certain molar ratio to a reaction tube with branched openings under the solvent-free condition; putting the reaction tube into a thermostatic oil bath with a magnetic stirring function; stirring for a certain time at a certain temperature in the atmosphere of nitrogen to enable materials to react to generate the product which is the phytostanol ester, wherein the phytostanol ester is generated after the reaction ends, the addition amount of the catalyst is 0.5-5.0mol% (relative to the molar weight of the phytostanol ester), the reaction temperature is 90-170 DEG C, and the reaction time lasts for 2-7 hours; sampling at fixed time, and measuring the conversion rate and the anisidine value to detect the reaction process; analyzing the product by infrared spectrum, mass spectrum and nuclear magnetic resonance spectrum to indentify the structure of the product, wherein the product is obtained by separating and purifying through column chromatography. The method is simple in process and high in efficiency and is suitable for large-scale production.
