Purac Powder, a coated malic acid from Purac, has been granted GRAS status and can now be used in confectionery, powdered beverages and jellies in the US.
A unique, stable acid powder, Purac Powder is a malic acid coated in sodium hydrogen malate which remains stable even in products with an extended shelf life and delivers an instant but long-lasting sour taste in the mouth.
Many acids used in confectionery applications are coated in fat, where hygroscopicity, acid migration and gelatin degradation can occur. This results in sticky or humid products with impaired visual appeal.
The migration issue means traditional acid powders have a duller acidic taste, especially in long shelf-life products. Purac Powder, however, has a coating made of partially neutralised polycarboxylic acid, which remains dry throughout the product's shelf life and then dissolves much faster on consumption than fat coatings.
