Absorbance
was measured at 510 and 700 nm, respectively, in different buffers
at pH 1.0 and 4.5, using A = [(A510
A700)pH 1.0
(A510
A700)pH 4.5]
with a molar extinction coefficient of cyaniding 3-glucoside of
29,600. Results were expressed as grams of cyaniding 3-glucoside
(C 3-G) equivalents per kilogram of fresh weight
