Extraction method of loofah seed oil

Abstract

The invention relates to an extraction method of vegetable oil, particularly to an extraction method of loofah seed oil. The method comprises the following steps: baking the loofah seeds, then crushing the loofah seeds into 90-mesh to 100-mesh powder, extracting the crushed loofah seed powder for 80 to 86 minutes in a SC-CO2 extraction environment that the pressure is 24 to 26 Mpa, the flow rate of the carbon dioxide is 50 to 52 L / h and the temperature is 35 DEG C, to obtain first loofah seed oil and extract residue, processing the extract residue for 15 minutes by virtue of ultrasonic waves with power of 180W, adding water into the processed extract residue according to the weight ratio of 1 to 1, pulping, adding protease into serous fluid to have enzymolysis to obtain enzymatic hydrolysate, deactivating the enzyme in the enzymatic hydrolysate, adding ethanol in a volume ratio of 1 to 15 into the enzymatic hydrolysate, processing for 30 to 34 minutes by virtue of ultrasonic waves with power of 80W to 82W, then centrifugally separating for 10 minutes at the rotation speed of 3000 r / min, to obtain second loofah seed oil, mixing the first loofah seed oil and the second loofah seed oil to obtain mixed oil, and distilling the mixed oil for 50 to 58 minutes under the pressure of 3 to 5 Mpa and the temperature of 50 to 58 DEG C to obtain the loofah seed oil.

Description

technical field [0001] The invention relates to a method for extracting vegetable oil, in particular to a method for extracting luffa seed oil. Background technique [0002] Loofah is rich in nutrients and contains a lot of vitamins, minerals, saponins, plant mucus, xylose and other substances. It is a seasonal vegetable that people love to eat. Loofah seeds are also called "Wu Niuzi". According to "Food Materia Medica": "The bitter ones will lead to flooding, the face and limbs will be swollen, and the water will make people vomit; Cure stone stranguria, spit roundworms". Domestic medical units use loofah seeds to treat children with ascariasis. The deworming effect is good, and the method of use is simple. Chew 30 loofah seeds on an empty stomach, and take it for 2 days. Loofah seeds also have the functions of moistening dryness and laxative, clearing heat and resolving phlegm. In recent years, studies have found that loofah seeds contain small molecule ribosome inac...

Problems solved by technology

Loofah seeds also have the functions of moistening dryness and laxative, clearing heat and resolving phlegm. In recent years, studies have found that loofah seeds contain small molecule ribosome inactivating protein immunotoxins, which have a strong inhibitory effect on human melanoma cells cultured in vitro , is a kind of oriented medicine with development potential. At present, loofah seeds are mostly used directly for medicinal purposes in the market. Although there is also the technology of extracting oil from loofah seeds, there are mainly shortcomings of low oil yield and large nutritional loss.
