  • Production of acylglycerol esters
    Patent number: 8076497
    Abstract: The present invention relates to the production of oil and fat containing acylglycerol esters including diacylglycerols, medium-chain and long-chain fatty acid triacyglycerols comprising esterification reaction between an acyl group donor and an acyl group acceptor in the presence of a heterogeneous chemical catalyst consisting of an ion-exchange resin preparation to obtain a reaction fluid that is further subjected to dehydration and at least one separation method, thus producing diacylglycerols and/or medium-chain and long-chain fatty acid triacyglycerols at a high yield in a short period of time.
    Type: Grant
    Filed: April 23, 2007
    Date of Patent: December 13, 2011
    Assignees: Universiti Putra Malaysia, Golden Hope Research Sendirian Berhad
    Inventors: Oi Ming Lai, Mohd Suria Affandi Yusoff, Seong Koon Lo, Kamariah Long, Chin Ping Tan, Shawaluddin Tahiruddin, Khairudin Hashim
  • Process for the production of diacylglycerol
    Patent number: 7943335
    Abstract: The present invention provides a process for producing a diacylglycerol, which comprises, reacting triacylglycerol with water and an enzyme preparation to obtain a mixture comprising of diacylglycerol, monoacylglycerol and free fatty acid; removing water content in the mixture by way of dehydration; and separating monoacylglycerol, free fatty acid and residual triacylglycerol by at least one separation method to obtain a high-purity diacylglycerol. An oil or fat composition comprising of diacylglycerol obtained from the process and phytosteryl esters and/or ferulic acid esters in an amount of from 0.5% to 25% by weight of diacylglycerol is also provided.
