Dosage
The recommended dosage is 0.02-0.1L of the enzyme preparation per ton of total raw materials, added at mashing or juice clarification. However, the optimal dosage depends on the fruit variety, maturity and the specific process parameters and should be determined by testing different dosages.
Package
Packaging specification: 1 kg / bag.
Storage
| Best Before | When stored as recommended, the product is best used within 6 months from the date of delivery. |
| Shelf Life | 6 months at 25℃, activity remains ≥85%. Increase dosage after shelf life. |
| Storage Conditions | This product should be stored in a cool and dry place in a sealed container, avoiding insolation, high temperature, and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement. |
Application
Due to the diversity of grape varieties, “picking” timing and maturities, the winemaker needs to define the dosage according to the actual local conditions. In situations where grapes are not squashy (firm and hard to squeeze), another ENZYMES.BIO’s product – Formulated Enzymes for Fruit Slurry is recommended because it contains more amylum. For fruits which are mature or have been stored for a long time, the polysaccharide may dissociate from the cell wall gradually. The pectin content will also increase so in these cases the dosage should be increased accordingly.
Safety
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa, so any direct contiguity with the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
