The influence of the chemical composition of modified lecithins on their surface-active and emulsifying properties

Новые технологии, 2023
It is known that lecithins are known to be natural emulsifiers due to the content of amphiphilic phospholipids. However, liquid lecithins widely produced by domestic enterprises have rather low emulsifying properties.

Investigation of the efficiency of the application of modified vegetable oil lecithins for the creation of encapsulated forms of micronutrients in the form of nanoemulsions

Новые технологии, 2022
Micro- and nanoemulsions are promising systems for encapsulating micronutrients for food enrichment. For the formation of stable nanoemulsions, it is advisable to use natural emulsifiers – modified lecithins of vegetable oils.

Comparative evaluation of the micelle formation process of phospolipids of rapeseed and sunflower lecithines in nonpolar solvents

Новые технологии, 2019
It is known that the ability of phospholipids in plant lecithins to micelle formation in solutions of non-polar solvents depends on their chemical composition.

Emulsifier and antioxidant properties of by-products obtained by enzymatic degumming of soybean oil [PDF]

, 2013
The enzymes used in degumming, called phospholipases, specifically act on phospholipids without degrading the oil itself. Degumming using a phospholipase C enzyme allows to meet all market specifications while it increases the oil yield.
