Diammonium hydrogen phosphate (DAP) is one of the key nutritional components essential for the production of quality wine, fruit liquor and alcohol. It is vital that nitrogen and phosphorus are readily available and easy to use for must fermentation to proceed correctly, especially at the beginning of the process. These elements, supplied by DAP, support the creation of new cell walls, enzymes and membrane proteins in the yeast. Diammonium hydrogen phosphate also ensures correct yeast activity and facilitates yeast reproduction. Therefore, from an oenological point of view, DAP ensures full and consistent fruit sugar fermentation.

    Thermal Process

    Food Grade Phosphates produced by Fosfa and Omnisal are extremely pure in terms of content of heavy metals and other impurities that usually come from raw materials.

    The contents of these elements in such products are controlled by strict European legislation. In our products, however, their real contents are even much lower than the limits required by the legislation. Our phosphates owe such superior quality in particular to the level of purity of our Phosporic Acid – the key raw material from which they are all produced. This level of excellence we could have achieved only thanks to the thermal method we employ in its production.

    The advantages of thermal process

    • Low content of heavy metals
    • Quality in line with all applicable EU legislation

    Thermal process = Eco friendly process

    • Minimum amount of waste during production
    • Emphasis on acid purity
