Abstract
Different formulations of tablets of bitter chocolate, white and milk, based on standard NEIAL - 6737: 2006, have been manufactured and evaluated. Hardness at 2 and 4 mm of penetration, consistency K calculated from Mottrams model, fracture stress and elastic modulus were determined. The results show that for hardness, significant differences (p ≤ 0.05) between the bitter pill and white were found. The values of consistency K were significantly different (p ≤ 0.05) indicating that there are differences in texture between the bitter chocolate bars, white and milk. For fracture, bitter and white tablets showed no significant differences (p ≤ 0.05) between them in terms of fracture stress or elastic modulus. But these, in turn, are fractured with significantly lower efforts than milk bars.
