説明
Using four anthocyanin pigments from Bailey Alicante A grapes and thirteen synthetic flavylium salts, the effects of two substituent groups(hydroxyl and methoxyl)on the stability of the pigment molecules have been studied in 0.2M tartaric acid-sodium tartrate buffer solutions(pH 2.5-4.5)at 50°C.(1)The pK values of the seventeen compounds investigated were determined spectrophotometrically.(2)The pigment molecules were stabilized by hydroxylation at the 5 and 7-positions in the benzopyrylium ring, and labilized by the same modification at the 3-position.(3)Since the instability of the pigment molecules increased with increasing hydroxylation in the B-ring(3', 4', and 5' -positions), it was suggested that the anthocyains hydroxylated at the ortho-position such as delphinidin-type pigments were labile.(4)The stability of the pigment molecules increased with increasing methoxylation in the B-ring.(5)From these results, it was proved that the malvidin-type pigments were the most stable.
