“…Ascorbic acid content decreased significantly (P=0.009) by 78% during storage in 1998 (Table 4). It was significantly lower (P<0.05) in 1999 than in 1998 and in 1998 a negative correlation was found between ascorbic acid and OP (Table 3) after harvesting, confirming results of Mulder (1949). The correlation between ascorbic acid and OP was not significant after harvesting in 1999 (Table 3), indicating that it has to be present in high quantities to be able to act as reducing agent.…”

“…Mulder (1949) found that discoloration of bruised potatoes results from oxidation of phenolic groups in the presence of polyphenol oxidase leading to the dark compound melanin. This enzyme has a wide substrate specificity (Stevens & Davelaar, 1996: Matheis, 1987.…”

“…During processing, polyphenol oxidases in potato tubers interfere with free phenolic compounds. In this process, polyphenol oxidases catalyse the formation of diphenols from monophenols, changing finally to dark melanins (Mulder 1949;Mondy et al 1965;Mondy and Koch 1978;Klein et al 1981;Muneta 1981). The role of Mg in these reactions is not clear, but the role of Mg in assimilation and carbohydrate translocation indicates that an improved Mg supply should have a positive effect.…”
