Problems solved by technology

[0002] Loofah, also known as Tianluogua, Tianluogua, Mangua, Tianluo, Miangua and Bugua, is an annual climbing herb of Cucurbitaceae. Because of its high yield and good quality, it can be used as both vegetable and medicine It is widely planted in the north and south of our country. The loofah seeds contain a variety of nutrients, and their oil content is extremely rich, which has high extraction value and development potential. Low efficiency, there are many non-oil substances in the leached oil, there will be solvent residues in the oil, and the safety is not high.

Embodiment Construction

[0011] 1) Soak the loofah seeds in water at a weight ratio of 1:3 for 24-26 hours and then squeeze the juice to obtain loofah seed juice. Add cellulase and protease to the loofah seed juice at a weight ratio of 0.005-0.008 for enzyme Decompose, obtain enzymolysis liquid and enzymolysis residue, separate enzymolysis liquid and enzymolysis residue;

[0012] 2) Bake the enzymolysis slag twice, the first baking is at a baking temperature of 130-135°C for 10-15 seconds, and the second baking is at a baking temperature of 45-48°C for 3-4 hours to obtain a roasted material;

[0013] 3) Press the baking material under the pressure of 680bar-7000bar to obtain pressed oil and pressed residue;

[0014] 4) Mix food-grade potassium hydroxide and ethanol at a weight ratio of 1:50 to obtain a separation liquid, heat the separation liquid to 50-55°C, mix it with the enzymatic hydrolysis liquid and pressing residue, and set the frequency at 156-168khz and power at After 20-22 minutes of ultr...

Abstract

The invention relates to a towel gourd seed oil extraction method. Towel gourd seed oil is obtained through technical treatment, including, soaking, enzyme hydrolysis, baking and reflux extraction. Squeezing and extracting technologies are adopted for compound extraction of the towel gourd seed oil, so natural nutrient components in the towel gourd seeds are remained to the maximum extent, the extraction rate of the towel gourd seed oil is 21.96%, and the residual amount of the solvent in the extracted towel gourd seed oil is zero; due to the low-temperature treatment technology, volatile oil in the towel gourd seeds is remained, the taste is natural and pure, the transparency is high, the extraction technology is simple, and the towel gourd seed oil extraction method has the advantages of being time-saving, efficient, energy-saving and the like.

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, also known as Tianluogua, Tianluogua, Mangua, Tianluo, Miangua and Bugua, is an annual climbing herb of Cucurbitaceae. Because of its high yield and good quality, it can be used as both vegetable and medicine It is widely planted in the north and south of our country. The loofah seeds contain a variety of nutrients, and their oil content is extremely rich, which has high extraction value and development potential. The efficiency is low, there are many non-oil substances in the leached oil, there will be solvent residues in the oil, and the safety is not high. Contents of the invention [0003] The object of the present invention is to provide a kind of luffa seed oil extraction method. [0004] The technical scheme that the present invention adopts is, a kind of luffa seed oil extraction meth...
