Method For Determining Oxidative Status Of Unsaturated Lipids And Method For Evaluating Antioxidant Effectiveness In Lipid-Polypeptide Layers
Method For Determining Oxidative Status Of Unsaturated Lipids And Method For Evaluating Antioxidant Effectiveness In Lipid-Polypeptide Layers
US Patent:
4253848, Mar 3, 1981
Filed:
Jan 21, 1980
Appl. No.:
6/114033
Inventors:
William L. Porter - Cambridge MA
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
G01N 3106, G01N 3302
US Classification:
23230HC
Abstract:
A method for rapid, dry, non-destructive assay of the oxidative status of unsaturated lipids in whole foods, fats or oils and a method for prediction of the storage life of such lipids are disclosed. A method for evaluating the effectiveness of natural or synthetic antioxidants in dry, thin layers of lipid supported on polypeptide is also disclosed. All of these methods depend on the fluorescence of compounds formed by the reaction of volatiles from oxidizing lipids and a polymerized epsilon-caprolactam.

Method Of Visually Detecting Antioxidant In An Organic Mixture
US Patent:
4257776, Mar 24, 1981
Filed:
Jan 21, 1980
Appl. No.:
6/114035
Inventors:
William L. Porter - Cambridge MA

Roslyn E. Kramer - Boston MA
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
G01N 3106, G01N 3108
US Classification:
23230M
Abstract:
Method of screening a mixture of organic compounds to detect the presence of an antioxidant material wherein the organic mixture is first chromatographically separated on a polyamide coated plate and then coated with linoleic acid. The plate is heated until the linoleic acid oxidation products react with the free amine groups on the polyamide material to produce a color change. Antioxidant compounds separated on the plate inhibit the color change and can be visually detected.
