Abstract

The invention discloses a process for producing flaxseed oil, and belongs to the field of technologies for producing edible vegetable oil. The process includes a raw material processing stage, a squeezing post-processing stage and a crude oil post-processing stage. The process has the advantages that litsea cubeba oil is added into raw materials in the raw material processing stage, oil is subjected to adsorption processing in the squeezing post-processing stage, accordingly, aflatoxin in the oil can be effectively removed, generation of aflatoxin can be effectively inhibited in post-opening storage procedures, and the storage lives of oil products can be prolonged; the process is high in oil yield, the flaxseed oil produced by the aid of the process is high in purity and quality, and influence on flavor and the quality of grease can be prevented.

Description

technical field [0001] The invention belongs to the technical field of edible vegetable oil production, and in particular relates to a production process of linseed oil. Background technique [0002] Aflatoxins exist in soil, animals, plants, and various nuts, especially grain and oil products such as peanuts, corn, rice, soybeans, and wheat. They are the most toxic mycotoxins and are extremely harmful to human health. . During the production of edible oil, aflatoxin can easily enter the edible oil, posing a threat to human health. The state stipulates that the content of aflatoxin B1 in peanut oil and corn oil shall not exceed 20 μg / kg, and the content of aflatoxin B1 in other edible oils shall not exceed 10 μg / kg. For the aflatoxin in edible oil, the current edible oil production process mainly adopts three methods: chemical alkali refining method, physical adsorption method and ultraviolet irradiation method to remove it. However, the current edible oil production proc...
