  • Process for the pre-treatment of vegetable oils for physical refining
    Patent number: 7494676
    Abstract: The present invention relates to a simple and economically attractive process for the pretreatment of vegetable oils which involves (a) enzymatic degumming with commercially available phospholipase A1 from the sources like Aspergillus oryzae microorganism, (b) bleaching of the enzymatically degummed oil using bleaching earth and activated carbon, and (c) dewaxing (in case of rice bran oil) of degummed and bleached oil at lower temperature to obtain oil with less than 5 ppm of residual phosphorus which is amenable for physical refining.
    Type: Grant
    Filed: May 30, 2003
    Date of Patent: February 24, 2009
    Assignee: Council of Scientific and Industrial Research
    Inventors: Pradosh Prasad Chakrabarti, Bhamidipati Venkata Surya Kopeswara Rao, Samir Kumar Roy, Lakshmi Anu Prabhavati Devi Bethala, Prasanna Rani Karna Narayana, Vandana Vemulapalli, Kalyani Chelimi, Gadam Karthika, Vijay Kale, Rachapudi Badari Narayana Prasad

  • Enzymatic process for the preparation of an acetylated phospholipid
    Patent number: 6403344
    Abstract: The present invention provides an enzymatic process for the preparation of an acetylated phospholipid from a lecithin by acetylating the lecithin in the presence of vinyl acetate and a catalyst comprising lipase from Mucor miehei having 1,3-position specificity, separating the desired acetylated phospholipid.
