Abstract

The invention discloses an edible oil refining method. The method comprises the following steps of: preparing crude oil; performing degumming performing deacidification; decoloring: adding activated clay into the deacidified crude oil to carry out primary decoloring treatment, carrying out solid-liquid separation to obtain pre-decolored crude oil, adding activated carbon into the pre-decolored crude oil to carry out secondary decoloring treatment, and carrying out solid-liquid separation to obtain decolored crude oil; deodorization: carrying out primary deodorization treatment on the decolorized crude oil through a plate-type deodorization tower, and then carrying out secondary deodorization treatment on the crude oil subjected to primary deodorization treatment through a filler deodorization tower, so as to obtain deodorized crude oil; performing refined filtration; freezing and filtering to obtain an edible oil finished product. The method is low in production cost, simple in technology, easy to operate and suitable for industrial application; impurities in the edible oil can be effectively removed, and the edible oil which is stable in quality, long in storage life and pure in color and flavor is obtained.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to an edible oil refining method. Background technique [0002] Edible oil is a necessary consumer product for people's life, and it is an important food that provides heat energy and essential fatty acids for the human body and promotes the absorption of fat-soluble vitamins. Among the many components of human food, oil has the highest value as a life energy source, with a calorific value of 37.7KJ / g, about twice that of protein and carbohydrates. [0003] With the rapid development of China's economy, the people's living standards have been greatly improved, and the quality requirements for edible oil are also continuously improved. Edible oil for health, nutrition. The refining method of edible oil has an important influence on the quality of edible oil products, such as appearance, nutritional components, flavor substances and content of toxic and harmful impurit...
