Embodiment 1

[0023] A method for reducing peroxide value and acid value of Ganoderma lucidum spore oil, comprising the following steps:

[0024] 1) Add 5 parts by weight of starch to 100 parts by weight of Ganoderma lucidum spore powder, after blending, add 0.5 parts by weight of wall-breaking enzyme, 0.1 part by weight of amylase and 10 parts by weight of vitamin E powder, and put it into a stirring container Stir, slowly pour liquid nitrogen until the temperature at the bottom of the container reaches about -50°C, slowly pour in purified water five times the weight of Ganoderma lucidum spore powder, until the temperature is 10°C;

[0025] 2) After stirring for 10 minutes, stop stirring and pour in liquid nitrogen again until the temperature at the bottom of the container reaches -10°C, close the sealing cover on the top of the container, open the vent pipe at the top and pass the vent pipe through the water seal anti-suckback device to prevent external air from re- into the container;

Abstract

The invention discloses a method for reducing peroxide value and acid value of ganoderma lucidum spore oil. The method comprises the following steps: 1) sequentially adding liquid nitrogen, purified water and liquid nitrogen into ganoderma lucidum spore powder, starch, wall-breaking enzyme, amylase and vitamin E powder, and carrying out heating in a water bath for an enzymolysis reaction for 3 hours; 2) adding NaHCO3 to adjust a pH value to 7.2, adding cultivation powder of bacillus subtilis, and carrying out stirring at a constant temperature of 38 DEG C for 1 hour; 3) carrying out low-temperature filter pressing, adding liquid nitrogen into an obtained filter cake, freezing the filter cake into blocks, carrying out vacuum drying, adsorbing oily substances on the upper layer of the filtrate, freezing the oily substances into blocks by liquid nitrogen, and carrying out vacuum drying; and 4) grinding a cake formed in the step 3) into powder, carrying out supercritical CO2 extraction to obtain spore oil, and then preparing a spore oil capsule. According to the method in the invention, wall breaking via lyase and supercritical extraction are combined, free oxygen in an enzymolysis system is removed through liquid nitrogen twice, then bacillus subtilis capable of consuming dissolved oxygen is added, and supercritical extraction is performed finally, so the spore oil in the whole production process is free of oxidation reaction and not prone to acidification and decay.

Description

technical field [0001] The invention relates to the technical field of purification of ganoderma lucidum spore oil, in particular to a method for reducing the peroxide value and acid value of ganoderma lucidum spore oil. Background technique [0002] The peroxide value is an indicator of the degree of oxidation of oils and fatty acids. is the active oxygen content in 1 kg of sample, expressed in millimoles of peroxide. Used to indicate whether a sample has deteriorated due to oxidation. For those foods made with oil and fat as raw materials, their quality and deterioration degree can be judged by detecting their peroxide value. [0003] Acid value is a sign of free fatty acid content in fat. During long-term storage, fat is slowly hydrolyzed by microorganisms, enzymes and heat to produce free fatty acid. The quality of fat is related to the content of free fatty acids in it. The acid value is generally used as one of the measuring standards. The acid value can be used a...
