shows an example of the ice-melting endotherms from heating the pan-sealed frozen crumb. In this particular case the sample was stored at -18 ºC for 11 days. A pronounced feature was that a considerable portion of ice crystals melted at ~0 ºC, indicating
- that they had grown up to bulk sizes over the storage period. Interestingly the major ice-melting peak also evolved into a narrow “spike”
