ENZYMATIC PREPARATION ENABLING COLOR EXTRACTION & STABILIZATION
Safizym® Col Plus is enzymatic preparation depectinizes the must and destabilizes the cellular walls of the skin, thus facilitating the migration of noble compounds (tannins, anthocyanins) to the liquid phase.
The pressing is helped and the disappearance of pectins (fouling colloids) allows an easier and less stressing subsequent filtration on the finished product. Enzymatic preparation produced by a selected Aspergillus niger strain.
Safizym® Col Plus technical features
• Short maceration: Safizym® Col Plus improves the varietal and aromatic expressions. The extraction is reduced which favors soft tannins.
• Long maceration: Safizym® Col Plus helps reinforcing the tannic structure of your wine without amplifying the astringency sensation.
Activity conditions
- Pectinases* : Endo polygalacturonase (> 1050 PG/g), pectin methyl esterase (> 210 PE/g) & pectin lyase (>30 PL/g)
- Active under oenological conditions (pH, SO2, high polyphenol levels)
- Active at low temperature (> 8°C) : cold maceration
- Active at high temperature (< 60°C) : hot maceration
- Rich in secondary hemicellulase activity
(*): method available on demand.
Effects
- Hydrolyzes the pectin chains of the must
- Enables the clarification and improves the pressability of the must
- Weakens the cellular wall and facilitates the extraction of phenolic (tanins & anthocyanins) and polysaccharidic compounds without intensifying the mechanic actions thanks to its hemicellulase activity
- Contributes to the softening of tannic structure and the final balance of the wine
- Contributes to the stabilization of the color (free of anthocyanase type secondary activities that are harmful to color stability)
Usage
Dilute the wanted dose in 10 times its own weight of water or must. This solution should not be stored more than a few hours. Incorporate the whole volume in the must that needs to be depectinized at the beginning of the tank filling. This supply will be homogenized during a pumping over or using micro oxygenation.
Dosage
The dosage of Safizym® Col Plus will depend on the cultivar, the maturity degree and the wine making process. Generally speaking, the dosages are the following:
Application at vatting: 1.0 to 3.0 g/hl
Application in vinomaceration: 1.0 to 2.0 g/hl
Application in cold maceration: 3.0 to 5.0 g/hl
Application on press wine: 2.0 to 4.0 g/hl
