Hydrogenated Oils: Overview, Types, and Applications

Published Categorized as Business

The Hydrogenation of oils and fats with post bleaching and deodorization process is a very important step in vegetable oil refining. Hydrogenated oils are available in two forms, namely fully hydrogenated and partially hydrogenated. Preserving the shelf life of food items is one of the most common applications of fully hydrogenated oils but when it comes to partially hydrogenated oil, things are different because it contains a huge amount of trans-fat and is not considered good for health at all. Trans-fat is responsible for raising the levels of cholesterol that lead to many complications related to the wellness of lipid profile.

Hydrogenation of oils and fats with post bleaching & deodorization process

According to The Food and Drug Administration (FDA), the hydrogenation of oils and fats with post bleaching & deodorization process plays a very important role in determining the overall quality of edible oils, and the oils that are partially hydrogenated should not be consumed as edible oils at all. This article sheds light on what hydrogenated oil is, its types, and why trans-fat is considered unsuitable and harmful for human health:

What is hydrogenated oil? 

The proper Hydrogenation of oils and fats with post bleaching and deodorization process results in hydrogenated oil which is a kind of fat that the food processing industry uses to preserve food items. In the hydrogenation process, hydrogen is added to vegetable oils to convert them into solid fat at room temperature.

Types of hydrogenated oils 

There are two types of hydrogenated oils:

  1. Partially hydrogenated
  2. Fully hydrogenated.

Partially hydrogenated oil (trans-fat)

In the past, the food processing industry around the globe used partially hydrogenated oil in the processing of a large number of food items. Some of them include:

  • A large number of baked products
  • Stick margarine
  • Frosting
  • Coffee creamers, and
  • Snack foods, etc.

When The Food and Drug Administration (FDA) declared partially hydrogenated oils unsafe for human use, its use in food processing was reduced to a large extent. The primary difference between fully hydrogenated and partially hydrogenated oil is the amount of trans-fat only.

Fully hydrogenated oil

Fully hydrogenated oil is the result of proper Hydrogenation of oils and fats with post bleaching and deodorization process which is carried out after the Dewaxing & Winterization of vegetable edible oil. As the name suggests, full hydrogenated oils get trans-fat-free after undergoing the process of hydrogenation. Just contrary to partially hydrogenated oil, the FDA has declared this oil safe for human consumption.

Major applications of hydrogenated oil

Resulting from the Hydrogenation of oils and fats with post bleaching and deodorization process after the dewaxing & winterization of vegetable edible oils, hydrogenated oils are used in:

  • Preserving the food items
  • Enhancing the flavor and texture
  • Cutting costs, and
  • Enhancing taste.

Concluding Remarks 

Mectech is one of the top manufacturers and suppliers of oil milling facilities for the Hydrogenation of oils and fats with post bleaching and deodorization process, and dewaxing & winterization of vegetable edible oil. The company has more than 45 years of dominating presence within the industry with a strong focus on innovation in its entire product range.
