Is Sodium Tripolyphosphate Safe Uses in Food
When it comes to food additives, many people think of preservatives and think it is bad for health. Food additives are actualy an artificial compound that is used to improve the color, taste of food and extend the shelf life of food. Without food additives, many foods in life will be harmful to health because of breeding bacteria. Adding preservatives to food can prevent or slow down the oxidation reaction of food, prevent food from spoiling due to microbial activity, and endanger the safety of consumers.
