For juice producers, oxygen is the ultimate enemy. The moment fruit is crushed, oxygen triggers enzymes that turn vibrant juice brown and destroy fresh aromas.
To solve this, KAAE has engineered a fully enclosed, oxygen-free processing line. Here is how we lock in natural flavor from start to finish:
1. Crushing Under Nitrogen Blanket
Traditional open crushers expose fruit pulp to ambient air. KAAE crushers feature a sealed chamber injected with food-grade Nitrogen . By displacing oxygen at the exact millisecond of crushing, we preserve the fruit’s natural color and aroma.
2. Sealed Vacuum Piping
We eliminate open troughs. KAAE lines use fully enclosed stainless steel piping combined with low-shear pumps. This prevents air from being whipped into the product during transfer between stages.
3. Vacuum Degassing (Deaeration)
Fruits naturally contain trapped micro-air bubbles. Before pasteurization, the juice enters the KAAE Vacuum Degasser. The vacuum environment forces dissolved oxygen to separate and escape, preventing “thermal oxidation” during heating.
4. Rapid Thermal Pasteurization
To completely stop the fruit’s internal browning enzymes, KAAE integrates High-Temperature Short-Time (HTST) systems. By heating the juice rapidly and holding it for just seconds, we destroy enzymes without “cooking” away the delicate flavors.
5. Aseptic Filling & Nitrogen Flush
The final defense happens at packaging. KAAE Aseptic Filling Systems fill and seal containers inside a sterile chamber flooded with nitrogen, ensuring zero oxygen is trapped in the headspace.
KAAE vs. Traditional Lines
Traditional Lines: Open air exposure ——>Rapid browning ——>Relies on chemical additives.
KAAE Sealed Lines: Closed-loop + nitrogen protection ——>Vibrant color——>100% natural flavor with extended shelf life.
