Potassium caseinate - Polylact
Description
Potassium caseinate - Polylact
Preparation intended for preventive and curative treatment of oxidation.
Qualified for the elaboration of products for direct human consumption in the field of the regulated use in Oenology. In accordance with the current EU regulation n° 2019/934 and the Food Chemical Codex (FCC).
POLYLACT® is a preparation associating PVPP and potassium caseinate that efficiently contributes to the adsorption of oxidised and oxidisable phenolic compounds while preserving the organoleptic potential of wines. The basic caseinate composition allows quick dissolution insuring a synergetic effect with PVPP. The absence of bicarbonate favours the preservation of the acid-base balance of wines.
Oenological applications
Specifically intended for preventive or curative treatment of musts and wines, white or rosé, with regard to oxidation likely to alter the colour and organoleptic qualities.
Physical characteristics

Protocol for use
Oenological conditions
- The treatment can be set up during each step of winemaking on musts and wines.
- The treatment is even more efficient as the product to be treated is clarified (enzyme treated must, racked wine).
- The risk of overfining with POLYLACT® is low, even at high dosage. The sedimentation is quick with an important settlement of lees forming very little deposit.
Dosage
On musts:
- Sound harvest: 20 - 40 g/hL (200-400 ppm).
- Spoiled harvest: 40 - 100 g/hL (400-1000 ppm).
On wines:
- 15 - 90 g/hL (150 to 900 ppm).
Maximum legal dose (EU): 260 g/hL.
Substance from cow’s milk presenting a potential allergenicity. The use of this product may cause an «allergen» labeling.
Implementation
- Dissolve POLYLACT® in 10 times its weight in water while maintaining an energetic agitation. It is recommended to let the solution swell one hour before use. The preparation can be incorporated before or during fermentation settling.
- The POLYLACT® solution must be used within the same day of preparation.
Storage recommendation
- Store above ground level in a dry area not liable to impart odours. Ensuring stock is kept at a moderate temperature, in its original, unopened packaging.
- Optimal date of use: 2 years.
Packaging
- 1 kg bag
