Reversibility of thermal degradation of betacyanins under the influence of isoascorbic acid

“…For aqueous solutions of beet pigments, the most useful isoascorbic acid concentration was found to be 0.1% (Bilyk et al, 1981). Isoascorbic acid, also known as erythorbic acid, is a stereoisomer of ascorbic acid and possesses significant antioxidant props (Esselen et al, 1945;Kadin and Osadca, 1959). The objective of the present study was to determine the effect of isoascorbic acid on thermally degraded betacyanines and betaxanthines, the two major classes of beet pigments.…”

Determination of reductones by high-pressure liquid chromatographic method.

“…As be seen in Fig. 1, the In comparison with other method of reductones such as colorimetric,12) polarographic,13) selenous acid,14) and pa perchromatographic method, 15) it has been demonstrated that HPLC is the most suitable one for the analysis of reductones. Assay of reductones using HPLC appeared to be more simple, rapid, and sensitive than GLC analysis 3) The analysis of reductones by using SAX-801 with 0.1M NaNO3 as the eluent would be expected.…”

Study of the Complexes of the Ascorbic Acid-Iron(III) System

“…In pharmaceutics they are widely used [2,3] and fulfill the function of an anti oxidizing agent in the food industry.…”
