Acidity regulators or pH control agents are food additives added to change or maintain the pH of the respective food.
Reason for addition : All fruits naturally contain some amount of acids like Citric, Malic etc. the kind & content varies depending on the type of fruit. For example, lemon or orange contain citric acid, apples contain Malic acids and so on. However, the natural acid content of fruits vary due to many reasons -
Season. (Pineapples are sweet during summers, but are sour during winters)
Harvesting stage.
Geographic location in which the fruit is grown impacts the acidity level as well. While manufacturing the Réal range of beverages & juices, the fruit/vegetable concentrates are sourced from across the globe to get the best organoleptic profile. This results in variation in the acid content of the beverages. Hence, to obtain a standardized product, acidity regulators (like citric acid) are added while manufacturing of Réal range of beverages. Rest assured, none of these measures harm the juice benefits.
INS 330 : There are many acidity regulators permitted under Indian regulations for fruit based beverages. INS 330 which is citric acid is one such permitted acidity regulator.
