E322 Lecithins is a complex mixture of acetone-insoluble phosphatides that consists chiefly of phosphatidyl choline, phosphatidyl etha nolamine, and phosphatidyl inositol, combined with various amounts of other substances such as triglycerides, fatty acids, and carbohydrates.
E322 Lecithins may contain any of these components in varying proportions and combinations depending on the type of fractionation used.
In its oil-free form, the prepon-derance of triglycerides and fatty acids is removed and the product contains 90% or more of phosphatides representing all or certain fractions of the total phosphatide complex.
The consistency of both natural grades and refined grades of E322 Lecithins may vary from plastic to fluid, depending upon free fatty acid and oil content, and upon the presence or absence of other diluents.
Its color varies from light yellow to brown, depending on the source, on crop variations, and on whether it is bleached or unbleached.
