Whats it like by enzymatic peeling
Pectinex Ultra SP-L results in:
- Highest possible quality
- Reduced losses duringprocessing
- Less manual labor costs

Citrus fruit processing Reduced viscosity and avoidance of problems in the
concentration (jellification of concentrated cloudy
material) Improved extraction of solids
Maintained cloud stability, if necessary

The new NZ 33095 for citrus processing
Due to its robustness (lowest pH, low and hightemperatures) extremly suitable for lemon
clarification More and stronger balanced enzyme activities and
better heat stability even at 60 C (10-60 C)
Better than competitor non gmo derived enzymes
Suitable for organic production Suitable for oil extraction
