Embodiment 1

[0028] Specific implementation steps:

[0029] STP1 dries the mushrooms;

[0030] STP2 grinds the dried mushrooms;

[0031] STP3 uses vegetable oil to extract the vitamin D2 in the mushroom powder in STP2;

[0032] STP4 adopts the method of physical separation to separate the mixture of oil and mushroom powder in STP3 to obtain oil.

[0033] The aforementioned mushroom is Agaricus bisporus.

[0034] The mushrooms are pre-treated before the STP1, and the pre-processing methods include: slicing and grinding fresh mushrooms.

[0035] The drying pretreatment method of STP1 mushrooms is as follows:

[0036] Dried directly so that the moisture in the mushrooms is ≤15%;

[0037] The drying method of STP1 includes hot air drying method and vacuum freeze-drying method. The process conditions of the hot air drying method are: 30-260°C, and the time is 10-300min; the process conditions of the vacuum freeze-drying method are: freezing temperature -80-0 ℃, the degree of vacuum is 0.3...

Embodiment 2

[0044] Specific implementation steps:

[0045] STP1 dries the mushrooms;

[0046] STP2 grinds the dried mushrooms;

[0047] STP3 uses vegetable oil to extract the vitamin D2 in the mushroom powder in STP2;

[0048] STP4 adopts the method of physical separation to separate the mixture of oil and mushroom powder in STP3 to obtain oil.

[0049] The mushroom is any one of oyster mushroom, crab-flavored mushroom, pleurotus eryngii, white jade mushroom, tea tree mushroom, bisporus mushroom, shiitake mushroom, Hericium erinaceus, Bailing mushroom and Coprinus comatus.

[0050] STP1 does not process before and directly proceeds to the next step.

[0051] The drying pretreatment method of STP1 mushrooms is as follows:

[0052] Pre-drying is performed first so that the moisture in the mushrooms is between 30% and 70%, and then drying is performed so that the moisture in the mushrooms is below 15%.

[0053] The drying method of STP1 includes hot air drying method and vacuum freeze-d...

Abstract

The invention relates to the technical field of grease extraction, in particular to a method for extracting vitamin D2 from mushroom powder by vegetable oil. The method comprises the following steps:STP1, drying mushrooms; STP2, grinding the dried mushrooms; STP3, exacting vitamin D2 in the mushroom powder of the STP2 with vegetable oil; STP4, separating a mixture of grease and the mushroom powder in the STP3 with a physical separation method to obtain the grease. The content of vitamin D2 in the grease produced by the invention is between 20 and 20000 IU/g, and no chemical agents such as organic solvent or enzyme and the like are adopted in the whole separation process, so that the obtained grease does not have chemical substance contamination.

Description

technical field [0001] The invention relates to the technical field of oil extraction, in particular to a method for extracting vitamin D2 in mushroom powder with vegetable oil. Background technique [0002] Grease is a collective term for oils and fats. In terms of chemical composition, oils are all esters of higher fatty acids and glycerol. Oils are derivatives of hydrocarbons. Grease is a special kind of ester. Oil in nature is a mixture of various substances, the main component of which is an ester formed by the dehydration of one molecule of glycerol and three molecules of higher fatty acids, called triglycerides. The main physiological function of fat is to store and supply heat energy, and the energy it can provide in metabolism is about twice that of sugar and protein. When one gram of oil is fully oxidized in the body, it can generate about 39.8 kilojoules of heat energy. In the patent document with the patent number CN201610011291, a method for extracting natu...
