Anhydrous Citric Acid E330 - C6H8O7 Specification

Citric Acid 330

 Hi food technologists and food scientists, This is Recipanda and welcome to our new journey on food additives and the purpose of these lessons is to learn how to choose your food raw materials from any supplier without problems.

We will start with the very common raw materials used in the food industry, whether it is  food or beverage, you need use food acid 330 for many purposes like (citric acid food preservative - Acidity regulator - adjust pH - flavouring agents).
