Analysis in food of free and ester bound MCPD, and of.
Method 3: In Assay 1, the sum of substances that generate 3-MCPD during the analysis (reportedly 3-MCPD esters and GEs) was determined. In parallel (Assay 2), we also determined the level of 3-MCPD resulting from MCPD esters after GEs’ elimination by acid treatment of the sample (3).
Abstract. 3-Monochloro-1,2-propanediol (3-MCPD) and 1,3-dichloro-2-propanol (1,3-DCP) are not only produced in the manufacturing process of foodstuffs such as hydrolyzed vegetable proteins and soy sauce but are also formed by heat processing in the presence of fat and low water activity. 3-MCPD exists both in free and ester forms, and the ester form has been also detected in various foods.
The process contaminants MCPD and MCPD fatty acid esters, together with glycidyl fatty acids, are not desired in foodstuffs. The higher levels of contamination in baby food or products made with palm oil, such as nut nougat creams and puff pastry products, are a subject of public debate.

GC-MS analysis of 3-MCPD fatty acid esters. By Minna Isotupa. Get PDF (365 KB) Abstract. 3-Chloro-1,2-propanediol (3-MCPD) and its esterified forms are food-borne contaminants. The chemical properties of fatty acid esters of 3-MCPD and their formation in foodstuffs as well as the analytical methods used to detect them were reviewed.
Title: Development and validation of analytical methods for the analysis of 3-MCPD (both in free and ester form) and glycidyl esters in various food matrices and performance of an ad-hoc survey on specific food groups in support to a scientific opinion on comprehensive risk assessment on the presence of 3-MCPD and glycidyl esters in food.
Committee on Food Additives (JECFA). 3-MCPD Esters are compounds formed during the processing and refining of vegetable oils and fats. 3-MCPD Esters have been shown to have a similar toxicological profile as 3-MCPD. Little is known on toxicological profile of 2-MCPD Esters, but current data show that 2-MCPD Esters are correlated with 3-MCPD Esters.
