Fig. 1 shows a typical freeze±thaw curve. A plateau in
temperature between 0 and 5C was evident in freezing
curves for samples with tcf of 12±120 min. However, for
samples with tcf of 180 and >900 min, these maxima
were not as obvious. This was particularly so with the
latter samples, which were held for approximately 15 h
at ÿ3.6C
