What is Interesterification used for?

Interesterification is a means of modifying the structure and functionality of fats and oils to produce food ingredients for a range of applications, which can help to reduce levels of saturated fatty acids (SFA) and trans fatty acids (TFA) in some foods, by providing an alternative to the use of animal fats or …

What is Interesterification process?

In the food industry and biochemistry, interesterification (IE) is a process that rearranges the fatty acids of a fat product, typically a mixture of triglyceride. The process implies breaking and reforming the ester bonds C–O–C that connect the fatty acid chains to the glycerol hubs of the fat molecules.

What is the difference between hydrogenation and interesterification?

Hydrogenation is used to improve the oxidative stability of oil and to modify the physical characteristics by reducing the double bonds (2). Interesterification changes the distribution and positions of fatty acids within and among triglycerides to change the physical properties and behaviors of oil (2).

What are enzymatic interesterification reactions?

Enzymatic interesterification is a process in which a lipase enzyme is used to catalyse the exchange of fatty acids attached to the glycerol backbone of a fat. Interesterification in which fatty acids are exchanged between two fats or within a fat has been used as an alternative to hydrogenation.

Is interesterified fat bad for you?

One study shows interesterified fat had the same unhealthy effects as trans fat, raising the bad LDL cholesterol and lowering the good HDL cholesterol. Interesterified fat may also raise blood sugar as much as 20 percent in some people. So until we know more, you may want to avoid it.

Are monoglycerides healthy?

The FDA classifies monoglycerides as ‘generally recognized as safe’ or GRAS, as food additives and ingredients, meaning that they do not pose an immediate health risk.

What is the difference between transesterification and interesterification?

is that transesterification is (organic chemistry) the reaction of an ester with an alcohol in order to replace the alkoxy group; it is used in the synthesis of polyesters and in the production of biodiesel while interesterification is (chemistry) the reaction of an ester with an alcohol in order to obtain a different …

Which catalyst is used in inter process?

The transesterification process is catalyzed by BrØnsted acids, preferably by sulfonic27 and sulfuric acids26,28,29. These catalysts give very high yields in alkyl esters, but the reactions are slow, requiring, tipically, temperatures above 100 °C and more than 3 h to reach complete conversion30.

What is bad about hydrogenated fats?

Trans fats raise your bad (LDL) cholesterol levels and lower your good (HDL) cholesterol levels. Eating trans fats increases your risk of developing heart disease and stroke. It’s also associated with a higher risk of developing type 2 diabetes.

Is diglycerides safe to eat?

According to the FDA, mono- and diglycerides are generally recognized as safe. They can be used in food without limitation, provided the manufacturing process is satisfactory.

Are monoglycerides the same as MSG?

Because MSG is the sodium salt of the amino acid glutamic acid, whenever glutamic acid is listed on a food label, the food always contains MSG, according to Vanderbilt University. MSG may also be listed as monopotassium glutamate or simply as glutamate.

How is interesterification used in the food industry?

In the food industry and biochemistry, interesterification (IE) is a process that rearranges the fatty acids of a fat product, typically a mixture of triglyceride. The process implies breaking and reforming the ester bonds C–O–C that connect the fatty acid chains to the glycerol hubs of the fat molecules.

Which is the correct way to describe interesterification?

Interesterification can occur in two ways: enzymatic interesterification or chemical interesterification (CIE). In chemical interesterification, a catalyst (most often sodium methoxide ), is added to a dry oil and the triglyceride exchange begins.

What is the purpose of interesterification of fat?

As is the case with the other oil modification processes, the purpose of interesterification is to alter the melting properties of the fat or fat blend in order to improve the functional properties of the product. The reaction requires the presence of a catalyst, and alkaline catalysts are generally used.

When does Enzymatic Interesterification ( EIE ) take place?

Enzymatic Interesterification (EIE) is the catalytic reaction that occurs when an enzyme is introduced into oil and rearranges the fatty acids on the glycerol backbone of a triglyceride. Triglycerides are either liquid or solid at room temperature.
