Hydrogenated fats are the product of the catalytic hydrogenation of unsaturated fats. The process is called hardening and is generally used to make concrete fats from oils. The main product is margarine.

What does hydrogenated mean?

Hydrogenation is a chemical process useful for the saturation (usually partial) of naturally polyunsaturated fatty acids; polyunsaturated fatty acids also have double bonds between the carbon atoms of the chain, consequently they bind fewer hydrogen ions than a saturated fatty acid.

What does totally hydrogenated mean?

Hydrogenation consists in the partial saturation of polyunsaturated fatty acids (vegetable oils), exploiting very high temperatures. We are talking about a range that goes from 120 to 210 degrees.

What are hydrogenated vegetable oils?

Hydrogenated fats | Glossary of Craftsmanship

for hydrogenated fats we mean the unsaturated fats of vegetable oils that are saturated through a chemical process.

What are hydrogenated fats and why are they bad for you?

Hydrogenated fats are actually similar to saturated fats of animal origin but have a greater detrimental effect on health because they contain trans fatty acids that promote the increase of LDL cholesterol and reduce HDL lipoproteins.

How does the hydrogenation process take place?

Hydrogenation is a chemical reaction where hydrogen is added to a substrate which can be a chemical element or compound, usually in the presence of a catalyst. … In the absence of the catalyst, the hydrogenation reactions require temperatures that are too high to be of practical use.

What are saturated and hydrogenated fats?

So can it be summarized by saying that saturated fats are the worst? “In reality, the worst fats are hydrogenated fats, fats that are brought to their solid form through a chemical process. Hydrogenated fats are for example those contained in margarine and in industrial products in general.

What are edible vegetable oils?

General The vegetable oils are obtained by pressing or by extraction with solvents from the fruits or seeds of many plants. … Among the vegetable oils, however, there are also some obtained exclusively or mainly from the pulp of the fruits; this is the case of palm oil and olive oil.

  • in the main fast food dishes.
  • in ready-made dressings and sauces.
  • in fried food.
  • in sweet spreads.

What are non-hydrogenated fats?

Those fats called “non-hydrogenated” are those obtained through a process called fractionation where the liquid part is removed from the oil, obtaining only the solid part. … While in fats called “refined” a totally industrial process is used that starts from the seeds of a plant.

Why are saturated fats bad for you?

They can therefore cause an increase in total cholesterol and LDL cholesterol (the “bad cholesterol”) with the natural consequence of a greater predisposition to cardiovascular diseases, such as heart attack, stroke and angina pectoris.

What are hydrogenated carbohydrates?

Hydrogenated fats are a group of fats that are obtained through the process of “hydrogenation”, which is a chemical reaction through which one or more multiple carbon bonds are reduced to simple bonds by the addition of hydrogen atoms, all at temperatures and high pressures.

How are hydrogenated fats obtained?

Follow the suggestions of the reference design. Hydrogenated fats are the product of the catalytic hydrogenation of unsaturated fats. The process is called hardening and is generally used to make concrete fats from oils. The main product is margarine.

What is the industrial process called for obtaining hydrogenated fats?

The industrial process of hydrogenation consists in heating vegetable oils to very high temperatures with the addition of hydrogen molecules and a metal catalyst (nickel, copper or platinum).

What does catalytic hydrogenation mean?

Catalytic hydrogenation is a type of reaction that involves the reaction of gaseous hydrogen with a species in the presence of a suitable catalyst.

What are healthy fatty foods?

What is meant by good fats and bad fats?

It is therefore important to make a clear distinction between good fats and bad fats. The former are extremely useful to the body and can be taken as nutrients. The latter, on the other hand, are harmful especially if taken over time.

What are the good saturated or unsaturated fats?

Unsaturated fatty acids are good for your health, saturated fatty acids should make up a very small part of the diet. Unsaturated fats satiate longer and are essential for the proper functioning of many important processes in the body.

How are vegetable oils obtained?

Vegetable oil can be obtained mainly in two ways: by chemical extraction or by mechanical extraction. Mechanical extraction is nothing more than the cold pressing (<60 ° C) of the seeds of oil plants.

Which seed oil is healthier?

The king of oils and seasonings is olive oil. Certainly the best for its characteristics, with an acidity not exceeding 0.8%. Protects from cardiovascular risk. It is the most recommended for its properties and is a fundamental part of the Mediterranean diet.

How to turn an oil into a fat?

Hydrogenation is a process used to transform oils from liquid to solid or semi-solid (margarine). It is a chemical method by which fatty acids are “partially saturated”, resulting in the transformation of a vegetable oil into a more solid fat.
