Grape/grapes total phenolics determination

A strong correlation has been demonstrated between visually determined grape contamination levels, and laccase activity (Table 10.12), but Redl and Kobler (1992) emphasized that the laccase concentration does not permit the estimation of the total phenolic compound decomposition level of rot contaminated grapes. Notably, there is no correlation between the laccase activity and the total phenolic compound index, determined by spectrophotometry at 280 nm. [Pg.294]
