(2) Compared to conventional lye peeling, IR dry-peeling using 30 to
75 s heating time showed a lower peeling loss (8.3%–13.2%
vs. 12.9%–15.8%), thinner thickness of peeled-off skin (0.39–
0.91 mm vs. 0.38–1.06 mm), and slightly firmer texture of
peeled products (10.30 to 19.72 N vs. 9.42–13.73 N) while
achieving an ease of peeling higher than 4.0. For the cultivars
studied, IR heating for 60 s is reasonable and can be expected
to achieve an ease of peeling of 4.5 or higher;
