Some food labels do not have preservatives

Many foods in supermarkets are labeled without preservatives and consumers mistakenly believe that these products do not contain food additives. In fact, preservatives are not synonymous with food additives, they are just one of a wide variety of food additives (Vietnam food Ingredient supplier) . The absence of preservatives does not mean that the food does not contain other food additives.

Not all foods must be added with preservatives. Foods with high moisture content, high carbohydrate and protein content and low acidity are the most likely to support the growth and reproduction of microorganisms, and are also the most prone to spoilage (Vietnam food flavour wholesale) , so preservatives are most needed.

However, acidic foods with pH below 4.6, such as yogurt and citrus juices, some foods with high sugar and salt (Vietnam food flavour supplier) , such as candied fruits (Vietnam food flavour wholesale) , candies, and foods with low moisture content, such as biscuits and dehydrated foods, do not need to add preservatives.

Moreover (Vietnam food flavour supplier) , it is not necessary to add preservatives to prevent food spoilage. High temperature, high pressure, irradiation (Vietnam food Ingredient supplier) , cryopreservation, vacuum or nitrogen-filled packaging can effectively prevent food spoilage, for example, canned food treated with high temperature and high pressure does not contain preservatives.

However, these preservative-free processed foods may contain other food additives, such as yogurt, thickeners in citrus juice, preserves (Vietnam food flavour wholesale) , sweeteners in candy, puffing agents in biscuits, colorants in canned meat, etc. Therefore, even foods labeled without preservatives may contain other food additives.
