Characterization Of Melting Properties In Dark Chocolates From Varying Particle Size Distribution And Composition Using Differential Scanning Calorimetry, Emmanuel Ohene Afoakwa, Alistair Paterson, Mark Fowler, Joselio Vieira
Professor Emmanuel Ohene Afoakwa
Melting properties in dark chocolates processed from varying particle size distribution (PSD), fat and lecithin content were studied using differential scanning calorimetry (DSC). Compositional parameters were PSD (D90 (90% finer than this size) of 18, 25, 35 and 50 lm), fat (25%, 30% and 35%) and lecithin (0.3% and 0.5%) contents. Variations in PSD had no influence on crystallinity of products. Fat and lecithin content influenced the degree of crystallinity and melting properties (Tend, Tindex and DHmelt) of the products. Increasing fat content caused consistent increases in degree of crystallinity and crystal size distribution, thus effecting significant changes in Tend, …
