Popis: | This research aimed to characterise an innovative ‘gelato’ (Italian-style artisanal ice cream) made by adding extra virgin olive oil (EVOO) as a functional ingredient, in order to provide health benefits and a characteristic flavour. We report the chemical-physical and sensory profile of an artisanal ‘gelato’ made by adding EVOO (10% w/w) characterised by medium biophenol content (228 mg kg−1) and a green-herbaceous flavour with a moderately bitter taste. The total phenolic content of the functional EVOO ice-cream was 25 ± 0.94 mg kg−1. The additional presence of EVOO added some key volatile compounds, including trans-2-hexenal, 1-hexanol, cis-3-hexen-1-ol and trans-2-hexen-1-ol. Sensory analysis indicated the presence of a slight pungent flavour and “freshly cut grass” aroma, with a slight bitter note given by the EVOO in the ice cream. These findings could lead to the formulation of ice creams in which EVOO is used to partially replace milk fat, with improvement of the nutritional profile, and designing new foods with innovative flavours. |
