Table 1. Browning index and clarity of osmotically extracted syrup from peel of Citrus junos in relation to freezing pretreatment

Freezing pretreatment
Non-frozen −20°C −70°C
Browning index (abs at 420 nm) 1.20±0.11b1) 2.00±0.10a 2.03±0.26a
Clarity (% transmittance at 650 nm) 95.31±1.32a 77.90±3.19b 78.74±8.61b
Values represent the mean±standard deviation (n=3). Means within each row followed by different letters are significantly different at p<0.05.
