Effect of different drying methods on bioactive potential and nutrients of medlar fruit
Drying period
The initial moisture content of medlars was reduced from 74.07 ± 0.04% to 11.75 ± 0.07%. Table 2 shows the drying times for the different drying methods. Shade drying had the longest drying time (22,500 min). The shortest…
