Influence of hazelnut flour and skin addition on the physical, chemical and sensory properties of vanilla ice cream

The effect of hazelnut flour (1.5, 3 and 4.5%) and hazelnut kernel skin (1, 2 and 3%) on the physical, chemical and sensory properties of vanilla ice cream was examined. All samples were analysed for pH, titratable acidity, total solids, nitrogen, fat, ash, overrun, viscosity, meltdown, Hunter L‐, a‐ and b‐values, flavour, body and texture, and appearance. The samples with hazelnut flour exhibited higher pH, nitrogen, ash, viscosity, and L‐, flavour, body and texture, and appearance values than the samples with kernel skin. Samples with hazelnut flour and skin can be added to the ice cream mix to produce a non‐fat ice cream at 3% and 1% levels in combination with maltodextrin, respectively.
