The sol was then stuffed into polyvinylidine casing with a diameter of 2.5 cm and both ends of casing were sealed tightly. Sols were incubated at 40 1C for 30 min,followed by heating at 90 1C for 20 min. The obtained gel was referred to as ‘kamaboko gel’. Modori gel was prepared by incubating the sol at 60 1C for 30 min,followed by heating at 90 1C for 20 min.
After heating,all gels were immediately cooled in iced water for 30 min and stored for 24 h at4 1C prior to analyses.
