Four types of sorbets were produced from each fruit studied – three with inulin (2, 6 and 8% by weight) and the other without inulin – using fresh fruit with the addition of water, stevia extract powder, pectin and lemon juice. The addition of inulin slightly increased the viscosity of blueberry sorbet and had a statistically insignificant influence on the viscosity of raspberry sorbet. Hardness of the berry craft sorbet samples was influenced more by the addition of 2 and 6% inulin.
