Effect of antioxidants in fresh cut radishes during the cold storage

The objective of this study was to evaluate the efficiency of antioxidants in the cold storage of fresh cut radishes. The shredded roots were submerged in the respective treatments during 3 min (ascorbic acid or citric acid) and stored at 5ºC and 90% RH during 10 days. The radish treated with ascorb...
