Provided are method and system for rapidly predicting foaming tendency of edible frying oil, including: heating the oil; immersing a polar component content detection probe into the oil to measure an initial polar component content of the oil; at a frying state, removing the detection probe from the oil, placing frying food into the oil and frying the same taking out the frying food from the oil after frying, and measuring the largest frying oil foam height and recording the same as an initial foam height; at an air introduction state, immersing the detection probe and introducing air into the oil, and continuing to introduce air and heat thereinto until the polar component content in the oil is 10%; repeating the frying state; and fitting measurements and parameters into a formula.

The present invention provides an edible blended vegetable oil for reducing blood lipids and cholesterol. The trace elements in the edible blended vegetable oil include 15-300 mg/kg of polyphenols, 290-1700 mg/kg of &#x3b2;-sitosterol, 260-1500 mg/kg of campesterol, 150-1000 mg/kg of stigmasterol, 140-600 mg/kg of squalene, 50-160 mg/kg of parkerol, 40-120 mg/kg of &#x3b3;-tocotrienol. The prepared edible blended vegetable oil of the present invention can achieve the effect of reducing blood lipids and cholesterol through a synergistic effect within the trace elements and a reasonable ratio within fatty acids. It is suitable for people with different health needs and has a broad market prospect and application value.

The present invention provides an enzymatic method for producing a fatty acid bornyl ester including using borneol and a fatty acid as a substrate for reaction and adding a lipase in a solvent system or a solvent-free system to catalyze the esterification reaction for a period of time to obtain fatty acid bornyl ester. The present method preferably uses fatty acids or their derivatives as acyl donors to prepare fatty acid bornyl esters. By utilizing the characteristics of the substrate, the synthesis process is simple; the reaction efficiency is high; and the content of fatty acid bornyl ester is up to 97%.

The present invention provides a method for vegetable oil deacidification by enzymatic amidation, which relates to the field of oil refining technology. The present invention is carried out through mixing high acid value vegetable oil with ethanolamine at a certain molar ratio in a solvent or solvent-free system, adding with a certain amount of lipase, and reacting at certain temperature for a period of time. The monoethanolamine has been used as an acyl donor for the first time to react with free fatty acid, which avoids the increasing amount of by-products and great loss of neutral oil in reaction that involved with triglycerides. The method of the present invention has the advantages of high selectivity, high catalytic efficiency, and environment friendly in the reaction. From enzymes recycling, it greatly reduces costs, which shows tremendous potential in the application.
