Edible oil is an essential food raw material in our daily life. It is not only a necessity for cooking, but also an important raw material for many food processing. However, the original extracted edible oil often contains various impurities and odors. In order to improve the quality and taste of edible oil, it must be refined, and deodorization is a very important step. Deodorization refers to removing the taste of edible oil itself and the odor produced during processing. During the processing of edible oil, due to different raw materials, different processing techniques and storage conditions, all kinds of odors will appear in edible oil. These odors will not only affect the taste and quality of edible oil, but also affect human health. Therefore, deodorization is an essential part in the process of edible oil refining.

There are various methods of deodorization, and the commonly used methods include distillation, adsorption and chemical deodorization. Distillation method is to heat edible oil, so that the odor substances in it can be volatilized, and then condensed and collected, so as to achieve the purpose of deodorization. The principle of adsorption is to use adsorbent to adsorb odorous substances in edible oil, so as to deodorize edible oil. The principle of chemical deodorization is to use chemical substances to react with odorous substances and convert them into harmless substances, so as to achieve the purpose of deodorization.
No matter what method is used for deodorization, it is necessary to strictly control the parameters such as temperature, pressure and time in the deodorization process to ensure the deodorization effect and the quality of edible oil. In addition, it is necessary to pay attention to the selection of appropriate deodorizers and adsorbents, and strictly control the dosage and regeneration conditions of deodorizers and adsorbents, so as to achieve the best deodorization effect.
Deodorization can not only improve the taste and quality of edible oil, but also prolong the shelf life of edible oil. Because many odorous substances will not only affect the taste of edible oil, but also accelerate the oxidative deterioration of edible oil, leading to the deterioration of edible oil. Therefore, deodorizing can not only improve the quality of edible oil, but also prolong the service life of edible oil and reduce the waste of resources.
In a word, deodorization is a very important step in the refining process of edible oil, which can not only improve the taste and quality of edible oil, but also prolong its service life. Therefore, in the process of edible oil production, it is necessary to strictly control the deodorization process and choose the appropriate deodorization method and deodorizer to ensure the quality and safety of edible oil.
