Austria Juice cuts sugar in fruit juice

Austria Juice has launched a fermentation-based process for reducing sugar and calories in 100% fruit juice, giving beverage manufacturers a new route into reduced-sugar juice without relying on artificial sweeteners.

The patent-pending process uses yeast fermentation to convert sugars before processing aids are removed. The fermented product is then blended with fruit juice concentrate to reach the required sugar profile. Austria Juice says the resulting juice contains at least 30% less sugar and at least 30% fewer calories, while retaining the identity of the original fruit juice.

Reduced-sugar apple juice concentrate is the first product being introduced at scale, with orange and multifruit options also available. The launch is aligned with the amended EU Breakfast Directives, which created a formal reduced-sugar fruit juice category. From 14 June 2026, products will need to deliver at least 30% sugar reduction to use the designation.

For juice manufacturers, the process addresses a formulation problem that has sat awkwardly within the category for years. Fruit juice carries a natural, familiar, and ingredient-led position, but its intrinsic sugar content makes it difficult to align with reformulation targets. Soft drinks can be adjusted through sweetener systems, flavour balancing, and acidity control. Juice is harder to change without affecting the product’s identity.

Fermentation gives processors another route. Rather than diluting juice, moving into nectar formats, or building a sweetener-led drink, the process changes the sugar profile of the fruit base itself. Austria Juice is also using FTNF — from the named fruit — aroma work to support flavour character after processing.

The approach sits within a wider reformulation shift in food and drink manufacturing. IN Food recently covered Arla Foods Ingredients’ work on lighter textures in protein bars, where lower-sugar, higher-protein, and texture-led positioning created production challenges beyond ingredient substitution. Austria Juice is working from the beverage side of the same trend: nutrition-led reformulation still has to survive industrial processing, sensory testing, and labelling scrutiny.

Juice has often been slower to move than carbonated soft drinks because the category depends heavily on the perception of naturalness. Consumers may accept sweetener systems in zero-sugar soft drinks, but 100% juice carries different expectations. A fermentation route gives manufacturers the possibility of reducing sugar while keeping a cleaner declaration and a recognisable product format.

The amended EU framework may also give manufacturers a clearer commercial target. Without a formal category, reduced-sugar juice risked sitting between established product definitions, with uncertain labelling value and unclear consumer understanding. A defined threshold creates a more concrete development brief for concentrate suppliers, private-label manufacturers, and branded beverage producers.

Industrial scale will determine how quickly the process moves into finished products. The system has to deliver stable flavour, repeatable sugar reduction, clean processing, and commercially workable costs. It also needs to avoid sensory drift between batches, particularly in apple and orange juice, where small changes in acidity, aroma, and sweetness can be obvious.

The launch also shows how fermentation is moving into practical mainstream processing roles. In this case, it is not being used to create a novel protein, alcohol, or functional ingredient, but to modify an established raw material for regulatory and nutritional demands. That gives the technology a more immediate route into conventional beverage manufacturing, where the value lies in making a familiar product fit a changing rulebook.
