Embodiment 1
[0021] The method for extracting snake oil in the present embodiment, concrete steps are as follows:
[0022] 1) Pretreatment: Extract snake fat, remove dander and impurities in the fat, and wash it twice with clean water, dry the surface moisture of the washed snake fat, and then put the snake fat in a freezer at a temperature of -7°C, freeze for 4.5 h, until it is completely frozen, then place the frozen snake fat in a high-speed crusher, and perform a high-speed wall-breaking treatment at a temperature of 4°C and a speed of 30,000r / min for 8 minutes to make a fat slurry;
[0023] 2) Ultrasonic-ethanol extraction: Add absolute ethanol solution to the fat slurry, keep the ratio of material to liquid at 1:4, and mix the solution in N 2 Under the protection of the ultrasonic transmitter, set the power of the ultrasonic transmitter to 350w, set the frequency to 40Hz, and heat the mixture to a temperature of 55°C, and perform ultrasonic treatment for 55min. 2 Under the protectio...
Embodiment 2
[0028] The present embodiment is the same as embodiment 1, and the difference is that in the method for extracting snake oil in the present embodiment, the rotating speed of the wall-breaking treatment in step (1) is 35000r / min, and the time is 5min, and the temperature is 10°C, and ultrasonic in the step (2) The power is 300w, the frequency is 50Hz, and the temperature is 50°C.
[0029] Weighing 2kg of snake fat, the prepared snake oil is 1.64g, and the oil yield is 82%.
Embodiment 3
[0031] The present embodiment is the same as embodiment 1, and the difference is that in the method for extracting snake oil in the present embodiment, the material-to-liquid ratio in step (2) is 1:3, the ultrasonic power is 400w, the frequency is 50Hz, and the temperature is 60°C, and the step ( 3) The mixed enzyme is protease and phospholipase with a mass ratio of 1:0.3, and the added amount is 2% of the mass of the filter residue. The adding sequence is to add phospholipase first, and then add protease after an interval of 15 minutes.
[0032] Weighing 2kg of snake fat, the prepared snake oil is 1.71g, and the oil yield is 85.5%.
