Product Description

Mono- and diglycerides of fatty acids (monoglycerides, in short) are typically based on fats and oils found in nature such as sunflower, palm or soybean oils. They occur naturally in some oils and are produced in the gastro intestinal tract as a product of the hydrolytic lipase activity in the upper part of the gastro intestinal tract, and are transported directly through the intestine wall (Schulthess et al., 2000).

For use in food applications monoglycerides are produced in a chemical process where glycerol of natural origin is interesterified with the triglyceride oils using an inorganic catalyst and high temperature. The reaction distributes the fatty acid moieties on the different glycerol molecules to form a reaction mixture consisting of glycerol, monoglyceride, diglyceride and triglyceride. The concentration of monoglyceride in the reaction mixture depends on the ratio between glycerol and triglyceride in the raw materials and is typically between 40 and 60 wt%. The reaction mixture is typically purified by removal of the excess glycerol and the catalyst. It is possible to concentrate the monoglyceride by distillation to obtain products with a monoglyceride concentration typically between 90 and 95 wt% or even higher.

The physical properties of the monoglyceride depend on the concentration of monoglyceride and the nature of the fatty acids used for preparation of the monoglyceride. Table 5.1 presents the melting points of distilled monoglycerides based on pure fatty acids and commercial products. Monoglyceride has a polymorphic nature and re-crystallises over time from the unstable subalpha and alpha forms to the stable beta crystalline form (Krog, 1997).
