Assay for the detection of beet sugar adulteration of food products
First Claim
1. An antibody raised against a proteinaceous component of beet sugar, said proteinaceous component of beet sugar comprising at least one proteinaceous material, found in beet sugar, selected from the group consisting of those proteinaceous materials, found in beet sugar, having a molecular weight as determined by carrying our electrophoresis on said proteinaceous material and comparing its mobility with that of marker proteins of known molecular weight, of about 61,000 daltons, about 45,000 daltons, about 39,000 daltons, about 36,000 daltons, about 30,000 daltons, about 27,000 daltons, about 21,000 daltons, and about 16,000 daltons.

Abstract
An immunoassay for the detection of beet sugar adulteration of sugar-containing materials such as fruit juices and fruit juice concentrates utilizes antibodies to proteinaceous components of beet sugar. These proteinaceous components have been found in all samples of beet sugar, tested, regardless of source or degree of refinement; these proteinaceous components have also been found in both crystal and invert sugars.

16. A method of detecting the presence of beet sugar in a sugar-containing material, said method comprising:
-
treating a test sample of said sugar-containing material to selectively recover proteinaceous materials therefrom to form a protein test sample; contacting said protein test sample with antibody raised against a proteinaceous component of beet sugar; and detecting the formation of complexes of said proteinaceous component and antibody. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
