Problems solved by technology

[0002] Flaxseed is an oil rich in a variety of functional substances, such as the well-known linseed oil with high α-linolenic acid and health functions, natural plant gum linseed gum, and lignans that have been proven to have anti-cancer functions etc.; in the main producing areas, linseed oil is the main edible vegetable oil in the daily diet, and the degree of commercialization in the early stage is low, and it is generally squeezed and consumed on the spot. The oil has a subtle nutty taste, but it is easy to produce a lingering bitter taste under normal temperature storage conditions, resulting in a decline in the taste and quality of the product; the current debittering process of linseed has major defects, and the traditional method has water degumming or activated carbon adsorption, etc., but the hydration degumming process has low efficiency, wastes water resources, and has defects such as incomplete degumming; activated carbon often causes linseed oil to have a fishy smell. Therefore, the current linseed oil degumming Bitterness method still leaves room for improvement

Embodiment 1

[0012] A process for debittering linseed oil. After filtering and removing slag from linseed crude oil, add it to a debittering tank, heat up to 50°C, then add silica gel to stir and mix for debittering, and at the same time, the debittering tank is evacuated or flushed with nitrogen; wherein, The stirring time is 2 hours, and the amount of silica gel added is 2% of the mass of linseed oil.

Embodiment 2

[0014] A process for debittering linseed oil. After filtering and removing slag from linseed crude oil, add it to a debittering tank, heat up to 60°C, then add silica gel to stir and mix for debittering, and at the same time, the debittering tank is evacuated or flushed with nitrogen; wherein, The stirring time is 1.5 h, and the amount of silica gel added is 3% of the mass of linseed oil.

Embodiment 3

[0016] A process for debittering linseed oil. After filtering and removing slag from linseed crude oil, add it to a debittering tank, heat up to 70°C, then add silica gel to stir and mix for debittering, and at the same time, the debittering tank is evacuated or flushed with nitrogen; wherein, The stirring time is 3 hours, and the amount of silica gel added is 4% of the mass of linseed oil.

Abstract

The invention relates to a debitterizing process for linseed oil. The process comprises the following steps: adding crude linseed oil into a debitterizing tank, then adding silica gel, and carrying out stirring, mixing and debitterizing, wherein stirring time is 0.5-4 hours, and the addition amount of the silica gel is 0.5-4% of the mass of the linseed oil. The debitterizing process is simple and convenient to operate; the flavor and nutritional ingredients of the linseed oil can be guaranteed; bitter precursor substances, namely some peptizing impurities in the linseed oil are removed by adopting the adsorptive silica gel; meanwhile, the debitterizing process of the linseed oil is determined by taking the phosphorus content as an evaluation index; and the linseed oil which can be stored for a long time and does not have bitter taste is prepared.
