Embodiment 1

[0015] Take 1000ml of bitter linseed oil, add 300ml of absolute ethanol, mix and stir for 60 minutes in a closed extraction container, adopt centrifugation to obtain 1004ml of linseed oil containing a small amount of solvent, and pass the linseed oil obtained above through low-temperature extraction equipment The solvent is extracted, the operating temperature is 60 degrees, the vacuum degree is 0.01MPa, the solvent ethanol is volatilized and recovered, and 998ml of pure linseed oil is obtained. The resulting linseed oil has no bitter taste. The above-mentioned bitterness is a human taste texture.

Embodiment 2

[0017] Take 1000ml of bitter linseed oil, add 350ml of absolute ethanol, mix and stir for 45 minutes in a closed extraction container, and use centrifugation to obtain 1005ml of linseed oil containing a small amount of solvent. Pass the linseed oil obtained above through low-temperature extraction equipment The solvent is extracted, the operating temperature is 60 degrees, the vacuum degree is 0.01MPa, the solvent ethanol is volatilized and recovered, and 999ml of pure linseed oil is obtained. The resulting linseed oil has no bitter taste.

Embodiment 3

[0019] Take 1000ml of bitter linseed oil, add 300ml of absolute ethanol, mix and stir for 45 minutes in a closed extraction container, and separate by standing to obtain 1007ml of linseed oil containing a small amount of solvent. The linseed oil obtained above is extracted by low temperature The equipment extracts the solvent, the operating temperature is 60 degrees, the vacuum degree is 0.01MPa, the solvent ethanol is volatilized and recovered, and 999ml of pure linseed oil is obtained. The resulting linseed oil has no bitter taste.

Abstract

The invention relates to an extracting debitterizing method of edible linseed oil, comprising mixed extraction: carrying out mixed extraction on linseed oil and a low-carbon alcohol solvent at room temperature according to the proportion of the volume ratio of 100:10-100:50 for 30-60 min; separation: enabling mixed liquor containing the linseed oil and the low-carbon alcohol solvent to stand or utilizing a centrifugal machine to centrifugally separate the mixed liquor into two phase, wherein one phase is an extraction solvent containing bitter matter, and another phase is an oil phase containing little solvent, and recycling the solvent for repeat use; and solvent extraction: carrying out low-temperature vacuum extraction on the oil phase containing little solvent, and recycling the low-carbon alcohol solvent, wherein, the extraction temperature is 35-60 DEG C, and the linseed oil is debitterized after the extraction is ended. The invention can effectively remove the bitterness in thelinseed oil, thereby obtaining the linseed oil the mouth feel and the taste of which have no bitterness. Therefore, the flavor of the linseed oil is effectively improved, and the original nutrition ofthe linseed oil is kept. The whole method is simple and convenient and effective, thereby facilitating implementation, industrial application and popularization.

Description

technical field [0001] The invention relates to a method for extracting and debittering edible linseed oil, belonging to the technical field of edible oil processing. Background technique [0002] Flaxseed oil is an edible oil rich in α-linolenic acid and has certain health functions. In the main producing areas, linseed oil is the main edible vegetable oil in the daily diet. In the early stage, the degree of commercialization was low, and it was generally squeezed and consumed on the spot. Most of the linseed oil was not refined for consumption. In recent years, with the increasing commercialization of linseed oil, new requirements have been put forward for the quality of linseed oil. As an edible oil, linseed oil must be refined to meet its physical, chemical and hygienic standards as a food. The original production of commercial linseed oil mostly adopts the "four removal" refining process of bulk oil, including degumming, alkali refining deacidification, adsorption deco...
