Problems solved by technology

However, because natural snake oil generally has an unpleasant peculiar smell or fishy smell, the widespread utilization of snake oil is limited. In addition, snake oil is rich in fatty acids, and traditional snake oil extraction uses high temperature to carry out, which easily leads to snake oil The unsaturated fatty acid in the snake oil is oxidized, and the active ingredients in the snake oil are destroyed, so there is an urgent need for a low-temperature extraction of snake oil and a process for removing fishy substances

Embodiment 1

[0023] A method for extracting snake oil at low temperature and carrying out deodorization and decolorization of snake oil, comprising the following steps:

[0024] 1. Remove the impurities in the raw snake oil;

[0025] Two, beating is carried out to obtain snake oil slurry;

[0026] 3. Add hot water at 55°C to the snake oil slurry, and after repeated washing for 3 times, take the above clarified liquid to obtain the snake oil stock solution;

[0027] 4. After adding 0.5% active carbon and activated clay that respectively account for the weight of the snake oil stock solution in the snake oil stock solution, reflux at a temperature of 50°C for 30 minutes to decolorize, then centrifuge at a speed of 6000r / min for 5 minutes, and take the clear liquid to obtain the first a snake oil;

[0028] Five, adding concentration in the first snake oil liquid is the ethanol of 80%, gets clarified liquid, decompression distillation obtains the second snake oil liquid;

[0029] 6. Add anh...

Embodiment 2

[0033] 1. Remove the impurities in the raw snake oil;

[0034] Two, beating is carried out to obtain snake oil slurry;

[0035] 3. Add hot water at 75°C to the snake oil slurry, and after repeated washing once, take the above clarified liquid to obtain the snake oil stock solution;

[0036] 4. After adding activated carbon and activated clay that each account for 1% of the weight of the snake oil stock solution in the snake oil stock solution, reflux at a temperature of 60°C for 10 minutes to decolorize, then centrifuge at a speed of 7000r / min for 8 minutes, and take the clear liquid to obtain the first a snake oil;

[0037] Five, adding concentration in the first snake oil liquid is the ethanol of 65%, gets clarified liquid, decompression distillation obtains the second snake oil liquid;

[0038] 6. Add anhydrous ether to the second snake oil to obtain the third snake oil;

[0039] Seven, carry out decompression distillation to the 3rd snake oil liquid and obtain snake oil...

Embodiment 3

[0042] 1. Remove the impurities in the raw snake oil;

[0043] Two, beating is carried out to obtain snake oil slurry;

[0044] 3. Add hot water at 85°C to the snake oil slurry, and after repeated washing twice, take the above clarified liquid to obtain the snake oil stock solution;

[0045] Four, in the snake oil stock solution, after adding gac and activated clay that each account for 2% of the snake oil stock solution weight, reflux at a temperature of 80°C for 60 minutes to decolorize, then centrifuge at a speed of 5000r / min for 5 minutes, and take the clear liquid to obtain first snake oil;

[0046] 5. Adding concentration to the first snake oil liquid is 75% ethanol, taking the clarified liquid, and decompressing distillation to obtain the second snake oil liquid;

[0047] 6. Add anhydrous ether to the second snake oil to obtain the third snake oil;

[0048] Seven, carry out decompression distillation to the 3rd snake oil liquid and obtain snake oil;

[0049] 8. Add ...

Abstract

The invention provides low-temperature extracted snake oil and a method for deodorizing and de-coloring the snake oil. The method comprises the following steps: pulping the snake oil; adding hot water of 55 DEG C to 85 DEG C into snake oil pulp; after repeatedly washing for 1 to 5 times, taking upper supernatant liquid to obtain crude snake oil; after adding a de-coloring agent, reflowing at 50 DEG C to 80 DEG C for 10 to 60 minutes; centrifuging at the speed of 5000r / min to 8000r / min for 5 to 10 minutes; taking supernatant liquid to obtain first snake oil liquid; adding ethanol with the concentration of 65 percent to 95 percent into the first snake oil liquid; taking supernatant liquid, and performing reduced pressure distilling to obtain second snake oil liquid; adding anhydrous diethyl ether into the second snake oil liquid to obtain third snake oil liquid; performing reduced pressure distilling the third snake oil liquid to obtain snake oil; adding mixed liquid of the anhydrous diethyl ether and absolute ethyl alcohol into the snake oil; performing reduced pressure distilling to obtain refined snake oil. The snake oil product prepared by the invention has no colored substances and polyunsaturated fatty acids are reserved to the greater extent; effective components in the snake oil are effectively prevented from being damaged, so that foreign flavor and undesirable smell in the snake oil are removed, and furthermore, the snake oil can be more widely utilized.

Description

technical field [0001] The invention relates to the technical field of animal oil extraction, in particular to a method for extracting snake oil at low temperature and removing fishy smell and decoloring snake oil. Background technique [0002] Snake oil is refined and extracted from the fat of snakes. The application of snake oil has a long history in my country, and its use as medicine first appeared in "Fifty-two Disease Prescriptions". Li Shizhen recorded the effect of snake oil in "Compendium of Materia Medica": snake fat "wraps the deafness with cotton, and also spreads swollen poison", and "rubs things, all penetrates." It shows that snake oil has strong penetration and has the effect of reducing swelling and poison. Traditional Chinese medicine often uses snake oil to treat chilblains and burns. Snake oil has strong affinity and permeability to skin and mucous membranes and is easily absorbed by the skin, and snake oil has the functions of accelerating skin metaboli...
