Recent Patents on Diacylglycerol Production and Applications

Many patents are available claiming the process for Diglyceride or Diacylglycerol (DAG) oil production through chemical and enzymatic approaches. The methods are esterification, glyceroloysis, hydrolysis, interesterification, and transesterification. Almost all the reactions used edible oil as a starting material. Majority of the inventors have patented their research for DAG production in relation with certain products such as margarine, mayonnaise, shortening, Omega-3 and others.
