cv. AB2, whereas the average firmness of cv. CXD179 was slightly lower
than that of cv. AB2 (Table 3). For both cultivars, the ANOVA analyses
show that the IR heating time significantly affected peeling performance
and peeled product quality(Tables 2 and 3). Compared to results for
each time level of conventional lye peeling, IR dry-peeling showed a
lower peeling loss, a thinner peel thickness, and a similar or slightly
firmer texture. For the purpose of achieving a better ease of peeling
(N4.5) with less heating time, IR heating for 60 s could be a reasonable
selection for both cultivars under the studied heating configuration.
Hence, the subsequent studies mainly considered the condition of 60 s
IR heating
