Linking physicochemical properties and sensory data in fibre-enhanced chocolate-based systemsTools Mouraka, Panagiota (2025) Linking physicochemical properties and sensory data in fibre-enhanced chocolate-based systems. PhD thesis, University of Nottingham.
AbstractSugar consumption is an increasingly significant public health concern, motivating the confectionery industry to explore alternative sweetening strategies in chocolate formulation. Chocolate is a mechanically complex fat-based suspension comprising sugar, cocoa, and milk solids, and is highly appreciated for its distinctive sensory properties and oral processing behaviour. These attributes contribute to consumer perceptions of chocolate as an ‘indulgent’, ‘restful’, and ‘luxurious’ treat. Importantly, many of these sensory qualities are linked to the presence of sucrose crystals, their size, solubility, and characteristic sweetness. The challenge lies in reducing or replacing sucrose without compromising the sensory experience or structural integrity of the final product.
