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...
