Ascorbic acid content of potatoes

Abstract

The ascorbic acid content in potatoes purchased on the local market, was determined for the different months of the year. By comparing our data with the ones from other authors, it was found that, for young potatoes the vitamin C levels obtained by us were among the highest. Furthermore, the loss resulting from storage is less intense here. As our climate allows at least two annual harvests, potatoes should be considered in this part of the country (São Paulo, Brazil), as a better source of vitamin C than in those countries subjet to a hard winter.
