For years artisan gelato makers saw frozen fruit as a “fallback option”. Today it is the other way round: quality gelato chooses frozen fruit deliberately, whenever fresh fruit lacks the stability or availability required.
What changes between fresh and frozen
For fruit destined for gelato, freezing produces three technical effects:
1. Water release. The rupture of cell walls during freezing releases water. In 100% fresh strawberry pulp, dry matter is around 9-10%. In the same pulp after thawing, free water is higher: it changes the total sugar calculation.
2. Aroma concentration. Water loss “concentrates” some aromas, while the more delicate volatile compounds are partially lost. The flavour is more “assertive” but less “fresh”.
3. Colour. Frozen fruit can lose brightness, especially in green shades (kiwi) and pale pink (peach). For strawberries and raspberries the colour remains practically unchanged.
When frozen wins
Three situations where frozen is technically the better choice:
Year-round continuity. Customers ask for strawberry, peach and raspberry even in December. Seasonal fresh fruit is not there. Frozen fruit processed at peak harvest beats imported out-of-season fresh fruit.
Consistent quality. A frozen batch is homogeneous by the tonne: same Brix, same pH, same aroma. Fresh fruit varies even between crates picked on the same day.
Microbiological safety. Rapid freezing knocks down surface microbial loads. For industrial gelato with subsequent pasteurisation, it is an extra level of safety.
When fresh remains superior
Fresh wins in two cases: “extra-virgin” single-portion gelato where the pastry chef wants a recognisable piece of fruit, and exotic tropical fruit gelato for which the available frozen product is of mediocre quality.
Usage percentages
For quality artisan-industrial gelato:
- Premium sorbet: 30-50% frozen fruit pulp.
- Traditional fruit gelato: 20-30% frozen fruit + milk base.
- Gelato with inclusions: 15-20% individually frozen cubes added to the base flavour.
- Toppings and ripples: pulps concentrated to 50-65 °Bx.
How to choose
Four parameters to check:
- Individual or block freezing: for cubes and pieces, individually quick-frozen is the better choice.
- Declared Brix: with no added sugar if you want a “clean” product.
- Certified drip loss: water loss at 4°C over 12 hours must stay below 6-8%.
- Stated origin: “Italy” is not enough — you need the variety and the growing district.
Handling in the lab
- Thaw in a cold room at +2/+4°C, never at room temperature.
- Use within 24-48 hours of thawing to avoid oxidation.
- Calibrate the recipe with a small pilot batch for every new supplier.
