The Quality of Milk Chocolate Bars by Substitution of Cocoa Butter, Milk Powder and Lecithin Soya – A Preliminary Study

Hasni Dian, Rahmad Dedy


Milk chocolate is most important products of confectionary that are well-known for its consumer, and a precious ended product in entirely value added chain in cacao. In chocolate industry, each ingredient plays an important role in product quality. This research aims to assess the possibility of substitution of cocoa butter and its impact on physiological appearance and sensory quality hedonically, to formulate optimum formulation of palm oil as cocoa butter substitute (0%; 10%; 20%), milk powder (0%; 10%; 20%) and lechitin (0.5%; 1%; 1.5%). Melting point and attribute preferences test were conducted for aroma, texture and flavour. Melting point were indicated that interaction within palm oil replacement and milk powder had significant impact to lowering the melting point of milk chocolate, whilst addition of lechitin up to 1% also decreased the melting point range. Attribute preference test from 40 untrained panellists evaluated that palm oil replacement up to 20% had improved the panellists preferences for aroma whereas it had contradiction effect for texture. For taste, additional milk powder up to 20% definitely enhances the taste preferences. Partial Least Regression shows that palm oil replacement had negative effect on aroma and flavour of milk chocolate, whereas it has positive impact on texture. The increase of additional of milk powder plays an negative impact as well to panellist perceptions towards aroma, flavour and texture. Lechitin as emulsifier influences significantly towards the aroma and flavour of milk chocolate, but not for texture. Sensory evaluation revealed that milk chocolate made from 10% palm oil substitution, 10% milk powder and 1% lechitin as more accepted hedonically as conventional milk chocolate.
