  • Rice bran-lipids based formulation and process for preparation thereof for selective delivery of genes to cancer cells
    Patent number: 9763881
    Abstract: The present invention relates to a formulation in which glycolipids and phospholipids, isolated from rice bran gum samples, were used in conjunction with gene carrying lipids to test its efficacy in delivering genes to cancer cells selectively. This formulation did not mediate efficient delivery of genes to non-cancerous cells, thus, showing potential use of this formulation to deliver anticancer therapeutics to cancer cells without eliciting treatment related toxicity to normal cells.
    Type: Grant

  • 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.

  • Process for the isolation of glycolipids
    Patent number: 6953849
    Abstract: The present invention relates to a process for the isolation of a glycolipid enriched fraction from rice bran oil by subjecting crude rice bran oil to at least two steps of dewaxing/degumming, treating sludge obtained as a byproduct of the second said dewaxing/degumming to hexane extraction, and separating the glycolipid fraction. The glyolipid fraction so obtained can be further purified.

  • Process for the isolation of glycolipids
    Publication number: 20020143173
    Abstract: The present invention relates to a progress for the isolation of a glycolipid enriched fraction from rice bran oil by subjecting crude rice bran oil to at least two steps of dewaxing/degumming treating sludge obtained as a byproduct of the second said dewaxing/degumming to hexane extraction, and separating the glycolipid fraction. The glyolipid fraction so obtained can be further purified.
