Food additives are substances added to food to preserve or enhance its flavor, taste, appearance, texture and aspect. Some additives and other types of ingredients have been used for centuries, for preserving food, by salting (bacon or fish), adding sugar (jam, fruit preserves) or by using sulfur dioxide, as done with wines.
Many different food additives have been developed over time to meet the needs of food production, as making food on a large scale is very different from making them on a small scale at home. Additives are needed to ensure processed food remains safe and in good condition throughout its journey from factories or industrial kitchens, during transportation to warehouses and shops, and finally to consumers. For cream, the food additives are used to enhance the stability of the product in contact with heat.
It is possible that the products make small particles when poured into a coffee. This reaction is completely normal and does not mean that the product is unfit for consumption. Just stir for the coffee and cream to mix.
