CN104845731A - Cucumber seed oil extraction method - Google Patents

Abstract

The invention relates to a cucumber seed oil extraction method. Cucumber seed oil is obtained through processes of immersion, enzymolysis, baking, reflux extraction and the like. Cucumber seed oil is compound extracted through a pressing and extracting technology, so that natural nutritional ingredients in cucumber seeds are maintained to the largest extent, the extracted cucumber seed oil solvent residual amount is zero, volatile oil in cucumber seeds can be retained through a low-temperature processing technology, fresh smell is provided, the acid value, the luster and the phospholipid content of cucumber seed oil reach the national secondary extracted oil standard basically, and after refinement, the saturated fatty acid content is increased, the oil yield reaches 45.32%, the linoleic acid content is as high as 78%, the acid value is low, and the unsaturated fatty acid content is 86%. The method has the advantages that extraction time is short, the efficiency is high, energy is saved, the product quality is good, pollution is prevented, and the content of linoleic acid components in the cucumber seed oil is increased apparently.

Description

A kind of Semen Cucumidis sativi oil extracting method

Technical field

The present invention relates to a kind of extracting method of Vegetable oil lipoprotein, particularly relate to a kind of Semen Cucumidis sativi oil extracting method.

Background technology

Cucumber is Curcurbitaceae annual herb plant, originate in India, China generally cultivates various places, grab fruit clavate, blackish green, green or Huang Zise, seed white, Long Circle, tender fruit makes fresh Lay or is processed into pickles, when cultivating the cucumber of excellent crystal seed, the cucumber that a large amount of grain is large and full can be left: seed, Semen Cucumidis sativi is the best secret recipe that synthetism among the people is strengthened bone and replenished the calcium, to osteoporosis, legs and feet knot, rheumatosis, sacroiliitis, the disease of the internal organs such as cervical spondylosis and liver stomach spleen lung has the function resuming treatment and keep healthy, current Semen Cucumidis sativi oil is commercially not general, it is low that extracting method also exists extraction efficiency, the non-oil substances contained is there is more in leaching oil, dissolvent residual is had in grease, the shortcoming that security is not high.

Summary of the invention

The object of the present invention is to provide a kind of Semen Cucumidis sativi oil extracting method.

The technical solution used in the present invention is, a kind of Semen Cucumidis sativi oil extracting method, and it comprises following steps:

1) Semen Cucumidis sativi is put into after water soaks 24-26 hour by the weight ratio of 1:3 squeeze the juice, obtain Semen Cucumidis sativi juice, in Semen Cucumidis sativi juice, add cellulase by the weight ratio of 0.005-0.008 and proteolytic enzyme carries out enzymolysis, obtain enzymolysis solution and Production With Residue of Enzymatic Hydrolysis, enzymolysis solution is separated with Production With Residue of Enzymatic Hydrolysis;

2) by Production With Residue of Enzymatic Hydrolysis roasting twice, first time cures and cure 8-10 second under the stoving temperature of 189-192 DEG C, and second time is cured and cure 15-18 minute under the stoving temperature of 65-70 DEG C, obtains curing material;

3) squeezing curing material at the pressure of 500bar-550bar, obtaining squeezing fluid and press residue;

4) food grade potassium hydroxide and ethanol are mixed to get parting liquid by the weight ratio of 1:50, parting liquid is heated to 50-55 DEG C, mix with enzymolysis solution and press residue, frequency be 150-165khz, after power processes 15-18 minute under being the ultrasonic wave of 210-220W, refluxing extraction 2-2.5 hour in the water-bath of 58-60 DEG C, and filtered while hot, obtain filtered liquid;

5) filtered liquid is put into distiller to boil under the pressure of 1937pa-2600pa, after reclaiming distillate, namely obtain Semen Cucumidis sativi oil.

The present invention adopts squeezing and extracting technology compound collecting Semen Cucumidis sativi oil, remain the natural nutrient component in Semen Cucumidis sativi to greatest extent, in the Semen Cucumidis sativi oil extracted, solvent residual amount is zero, Low temperature processing techniques can make ethereal oil in Semen Cucumidis sativi remain, there is fresh scent, the acid number of Semen Cucumidis sativi oil, peroxide value, color and luster and phospholipids content reach the standard that national secondary leaches oil substantially, after refining, saturated fatty acid content raises, oil yield reaches 45.32%, linoleic acid content is up to 78%, acid number is lower, unsaturated fatty acid content is 86%, extraction time is short, efficiency is high, save energy, good product quality, pollution-free, and significantly improve the content of Semen Cucumidis sativi oil Linoleic acid component.
