What are acidifying and pH regulating additives? Discover what they are, what they consist of and their purpose, their toxicity and in what foods or drinks we find them.

The truth is that it is enough to take a look at food labels to realize the amount of food additives that we can find in food, and food products and beverages that we consume with some regularity.

As its name suggests, food additives are substances or compounds that are added to food and beverages, with the aim of improving their taste and aroma, or to extend their expiration period.

As we have told you on several occasions, there are different types of food additives that differ depending on their qualities or purposes: colorants, preservatives, emulsifiers, antioxidants and stabilizers.

However, it is true that if we talk about acidifying additives, and particularly those  regulating the pH of food, it is more than likely that they do not sound as familiar to you as the previous ones.
