  1. Samples included fresh commercial chocolate, molten and recrystallized commercial chocolate with added 0.1% (w/w) dimyristoylphosphatidylcholine (DMPC), molten and recrystallized commercial chocolate with added 0.1% (w/w) dipalmitoylphosphatidylethanolamine (DPPE), molten and recrystallized commercial chocolate. The molten and recrystallized samples were crystallized at 5 °C for 1 h and stored at 20 °C for 4 days. Values represent the means and standard errors for 4–16 replicates for EB and WI and for 3 replicates for melting temperature. Values with the same superscript letter within a row are not significantly different (P > 0.05).
  2. *There is a significant difference between these values at P < 0.1.
