    Benefits
    • Faster and more consistent liquefaction
    • No danger of resistant or retrograded starch formation
    • Reduced processing costs through more efficient liquefaction
    • Improved flexibility in using various cereal grain adjuncts
    Dosage
    The recommended dosage is 0.2-0.5L of the enzyme preparation per ton of starch, added at liquefaction. However, the optimal dosage depends on the specific process parameters and should be determined by testing different dosages at the brewery.
    Recommended Storage


    Best before

    When stored as recommended, the product is best used within 12 months from date of delivery.

    Storage at customer’s warehouse

    0-15℃

    Storage Conditions

    This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability.

    Safety and Handling Precautions
    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 human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
