Processing method for flaxseed oil

Abstract

The invention discloses a processing method for flaxseed oil. The processing method comprises the following steps of: (1) squeezing flaxseeds into crude oil; (2) carrying out dephosphorizing treatment on the crude oil; (3) degumming and dewatering to obtain finished oil; and (4) dewaxing the finished oil. The processing method has the advantages that the decoloring and deacidifying are not needed, and the addition of chemical decoloring agent is avoided; the dewaxing process is simple to operate, the crystallization time is short, the industrialization production is easy, the dewaxed faxseed oil is clear and bright in color, no deposition exists during storage, the quality of the oil products can be promoted, the flaxseed oil is easily digested and absorbed after being eaten, and the economic benefits of the product can be increased; and the method is simple in technique, the refining time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a processing method of linseed oil. Background technique [0002] Flaxseed oil is the oil extracted from flaxseed. Flaxseed (flaxseed or linseed), also known as flaxseed, is the seed of flax, an annual or perennial herb of the family Linaceae and the genus Flax. Flax is one of the oldest fiber crops in the world. There are many varieties, but they can be roughly divided into three categories: flax for oil, flax for fiber and flax for oil and fiber. One of the oil crops, its output occupies the seventh place. [0003] At present, the pressing method of linseed oil is unreasonable. For example, (1) in the past, when processing linseed oil, the color of the crude oil turned black because the raw material was fried or the pressing temperature was not reasonably controlled even though it was not fried. The color cannot meet the requirements of the national standard, so...

[0003] At present, the pressing method of linseed oil is unreasonable. For example, (1) in the past, when processing linseed oil, the color of the crude oil turned black because the raw material was fried or the pressing temperature was not reasonably controlled even though it was not fried. The color cannot meet the requirements of the national standard, so decolorization treatment is required; (2) Since the time of crude oil refining is not strictly controlled, the crude oil is in contact with air for a long time and oxidation occurs continuously, causing the acid value to increase, so deacidification is required Most of the decolorization and deacidification processes need to add chemical preparations. On the one hand, the refining process is complicated, the refining time is long, and the production efficiency is low.

[0004] Because there are jelly and wax in the epidermis, shell and cell wall of flaxseed, after the oil is squeezed out of flaxseed, the wax dissolves in the oil. After eating, the digestion and absorption rate will decrease, which will have a potential negative impact on the human body and reduce The nutritional value of the oil is reduced; and the waxy oil is not conducive to the storage of the product, and it is easy to precipitate after a long time, and the oil is turbid at low temperature, which affects the quality

However, the traditional cooling crystallization method takes a long time to crystallize, is difficult to operate, has high requirements on the surrounding environment, and is time-consuming, labor-intensive and expensive.
