Problems solved by technology

In the present invention, the oil residue after oil extraction is used as the raw material, and the amygdalin is first refluxed to extract the protein, and then the protein is extracted by the alkali-dissolving and acid-precipitating method, so as to obtain amygdalin and protein powder products; although this method can obtain high-content pure amygdalin product, but the removal of oil and protein impurities in almond oil residue was not considered in the process design process, so that the final product contains a small amount of oil and protein, which affects product quality
In addition, although the method of recrystallization can get rid of some impurities, it increases the production cost. It can be seen that the extraction method has the defects of high cost and very complicated extraction process.

Embodiment 1

[0026] refer to figure 2 Shown, a kind of method for separating amygdalin from almond oil residue, carries out by following steps successively:

[0027] (1) Mixing material: crush the almond oil residue to 100 mesh, add 0.4-0.6 times the amount of activated carbon and 0.4-0.6 times the amount of diatomite to the total weight of the almond oil residue according to the mass ratio, and mix well Stir well and set aside;

[0028] (2) Extraction: Put the fully mixed and evenly stirred raw materials into the extraction equipment, heat to 72°C-78°C with 5 times the amount (weight / volume) of ethanol, and extract for 6-7 hours;

[0029] (3) Filtration and crystallization: The extracted liquid is directly filtered with a plate-and-frame filter and a 0.2-micron membrane while it is hot, and placed in a clean container to stand overnight;

[0030] (4) Centrifugal drying: After overnight crystallization of the mixed solution, pour it directly into a centrifugal dryer to dry, and directly...

Embodiment 2

[0034] According to the mass ratio, take 1.5 kg of raw materials, mix them with 0.75 kg of activated carbon and 0.75 kg of diatomaceous earth, mix them evenly, put them in a 20L jar, add 7.5L of ethanol, heat at 75°C for 6 hours, filter the extract with a 0.2 micron membrane and leave it overnight , and carried out crystallization and suction filtration according to the inventive process, and dried at a temperature of 75° C. for 24 hours to obtain 45.3 grams of the product, the content detection was 98.33%, and the yield was 75.42%.

Embodiment 3

[0036] According to the mass ratio, take 10 kg of the same batch of raw materials, mix them with 5 kg of activated carbon and 5 kg of diatomaceous earth, mix them evenly, put them in a 200L extraction tank, add 50L of ethanol and heat at 75°C for 6 hours, and filter the extract with a 0.2 micron membrane and place it Overnight, crystallization and suction filtration were carried out according to the inventive process, and 305 grams of the product were obtained after drying at a temperature of 75° C. for 24 hours. The content was detected to be 99.13%, and the yield was 76.25%.

Abstract

The invention discloses a method for separating amygdalin from almond oil residue by one-step solvent extraction, which sequentially comprises the following steps that 0.4-0.6 time of activated carbon and 0.4-0.6 time of diatomite are added into the total almond oil residue, and are fully mixed uniformly with the almond oil residue; the raw material is put into an extraction device, is heated with 5 times of ethanol, extracted, filtered, crystallized, and then put into a clean container for standing still overnight; and the obtained material is centrifugally dripped and eluted with the ethanol, a product is directly put into a blast drying oven to be dried for 24 hours, and then the amygdalin is obtained. The product has good color and appearance and high quality and purity, the operation is simple and rapid, the investment of equipment is greatly reduced, the yield of the product is more than 78%, the purity of the product is more than 99.0% and maximumly achieves 99.9%, the recovery rate of various solvents can reach more than 92%, and the BOD (Biochemical Oxygen Demand) of waste water is lower than 100, which is suitable for industrial production; and the method is widely used in the industrials of health care products and medicines.

Description

technical field [0001] The invention relates to a saponin extraction method, in particular to a method for separating amygdalin from almond oil residue. Background technique [0002] Fiji, an island country located in the South Pacific, has never suffered from cancer. It is the only cancer-free country in the world discovered so far. Scientists have found that Fijians do not suffer from cancer because of their unique eating habits: they like to eat dried apricots and almonds. [0003] Almonds contain a lot of amygdalin. Therefore, it has a strong anti-cancer and anti-cancer activity. American scientists used amygdalin to 4,000 terminal cancer patients, and proved that it has a significant effect on cancer. [0004] Because of its unique anti-cancer and anti-cancer activity, amygdalin has attracted more and more attention, and the market demand is also growing at a relatively high rate every year. [0005] Due to the novelty of amygdalin in the future market and the stri...
