Title:Sensory attribute ratings of chocolate spreads

Description: The dataset contains sensory attribute intensity ratings on three samples of orange-flavoured chocolate spreads purchased from three UK commercial brands. The samples were evaluated by two separate panels, one trained panel (n=7) and the other untrained (n=24). Each panel rated the intensities of five attributes- orange flavour, sweetness, cocoa flavour, milky flavour and saltiness on an 8-point categorical scale (from 0-7). RedJade sensory software was used for data collection between November and December 2022.

5. METHODS
----------
- Data was collected through sensory evaluation surveys using Redjade Sensory software (https://redjade.net/)
- Attribute intensity rating test was used to evaluate the samples using an 8-point categorical scale (0-7) with labels adapted from the Labelled Magnitude (LMS) Scale.
