    Sodium Carbonate (Soda Ash)

    Sodium Carbonate (Soda Ash) – Acidulants & Food Salts product from Bio Green Foods

    About This Product

    Sodium carbonate has the formula Na2CO3, CAS number 497-19-8 and the European additive number E500(i). It is supplied as a white powder or granule in dense and light grades, is very soluble in water and gives a strongly alkaline solution around pH 11. Most commercial material is made by the Solvay process or mined as natural trona.

    The distinction from sodium bicarbonate matters in practice. Bicarbonate is only mildly alkaline and is used to generate gas by reacting with an acid; carbonate is far more alkaline and is used where high pH is itself the objective. In noodle manufacture it is the main component of alkaline kansui solutions, raising dough pH so that the gluten network tightens and the flour's flavonoids turn yellow, producing the firm bite and colour of ramen and many Asian noodles. In cocoa processing it neutralises acidity to darken colour and mellow flavour. It is also used to adjust pH in processing water, to assist in removing skins from fruit and vegetables, and as a component in some water treatment and cleaning applications in food plants.

    It is used in Asian noodle production, cocoa and chocolate processing, as an acidity regulator, in fruit and vegetable processing and in food-plant water treatment.

    Bio Green Foods supplies food-grade sodium carbonate to specification on assay, loss on drying, chlorides, sulphates, iron, arsenic and heavy metals.
