Carboxymethylcellulose (CMC) is a common food additive that is used as a thickener, stabilizer, and emulsifier in a variety of processed foods. CMC is derived from cellulose, a natural polymer found in plants, and is produced by treating cellulose with sodium hydroxide and then reacting it with chloroacetic acid to produce carboxymethyl ether derivatives.
CMC is widely used in the food industry because it is cheap, easy to use, and has a wide range of applications. It is used to thicken and stabilize a variety of products such as sauces, dressings, baked goods, dairy products, and meat products. It is also used as a fat substitute in low-fat or reduced-calorie foods because it can create a creamy texture without adding extra calories.
Here are some examples of foods that may contain CMC:
It is important to note that while CMC is generally recognized as safe by regulatory agencies such as the US Food and Drug Administration (FDA), it may cause some digestive discomfort in some people. Some people may experience bloating, gas, and diarrhea when consuming products containing CMC. It is always a good idea to read food labels carefully and consume processed foods in moderation. If you have concerns about consuming CMC or other food additives, it is always a good idea to consult with a healthcare professional.
