Data on the sensory evaluation of WMP, sugar and cocoa butter substituted chocolates revealed that 40% (w/w) of WMP, sugar and cocoa butter can be successfully substituted by FFSF, stevia-mannitol blend and SBO, respectively in the preparation of high protein and low sugar chocolate without impairing the sensory attributes. Lecithin was found to be optimum at 0.32% (w/w) level of chocolate mix. Protein content of optimized formulation increased by 21.8% over control. Storage study of the product indicated an increase in hardness, free fatty acid content, peroxide value, total plate count, yeast and mold count, whereas a decrease in moisture content, pH value and sensory scores. The optimized chocolate was found acceptable (score >= 7.0) after 90 days of storage at 16 +or- 1 degrees C and ~65% RH. 收起
