Abstract:
New potential uses of pectates in food products have recently stimulated interest in re-evaluating the information available concerning the safety of pectins and pectates as food ingredients. Data relevant to this re-evaluation have been obtained in rats in recent 14-day and 13 wk subchronic feeding studies with sodium pectate. Ames tests and other mutagenicity tests have been conducted with sodium pectate, bleached sodium pectate and mixed sodium/calcium pectate salts. These toxicological studies with pectates have provided further evidence of their safety, and support of the continued GRAS status of pectins and pectate salts.

SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
