As shown in Table 3, the adhesiveness values of cooked rice
ranged from 0.02 N s to 7.84 N s with different freezing rates during
chill storage for 0e14 days. Fresh cooked rice (storage 0 day) frozen
with a rapid freezing rate (1.45 C/min) was observed to have
higher adhesiveness (7.84 N s) than other freezing rates. Most
decrease in adhesiveness values occurred within 3 days storage.
The adhesiveness decrease continued up to 7 days and then slowed
down during the last 7 days. Amylose retrogradation and amylopectin
retrogradation contributed to the adhesiveness decreased
during storage (Yu et al., 2009). The faster the freezing rates, the
less freezing time and starch retrogradation. Therefore, the cooked
rice frozen with fast freezing rates showed higher adhesiveness
values than that with slow freezing rates.
