  • Patent number: 4797300
    Abstract: Plastic shortening and other food compositions which comprise an edible oil and a fatty acid ester of sucrose wherein the fatty acid groups consist essentially of short chain fatty acid radicals containing from 2 to 10 carbon atoms and long chain fatty acid radicals containing from 20 to 24 carbon atoms in a molar ratio of short chain:long chain radicals of 5:3 to 3:5, the said esters having a degree of esterification of about 7 to 8. The edible oil can be a triglyceride oil or a nondigestible oil.

    Assignee: The Procter & Gamble Company
    Inventor: Ronald J. Jandacek
  • Patent number: 4241054
    Abstract: Non-absorbable polyol polyesters dissolve toxic lipophilic compounds in the stomach and intestine of humans and lower animals and thus decrease their absorption. The polyol polyesters also dissolve the toxic, lipophilic materials and their metabolites if they are excreted in bile, and prevent their resorption. The invention thus provides a means for detoxifying humans and lower animals which have ingested toxic lipophilic materials (e.g., DDT, Kepone, PCB, PBB) by accelerating the excretion of such materials that have accumulated in the body. The process involves oral administration to a human or lower animal in need of such treatment of a sufficient amount of a non-absorbable polyol fatty acid polyester to effect detoxification.
