Application of Sodium Carboxymethyl Cellulose - Convenience Food

Instant noodles are ubiquitous in daily life, and the incorporation of carboxymethyl cellulose sodium (CMC) is a notable aspect of their production process.

When CMC is combined with flour, it enhances the toughness and chewiness of the noodles, thereby preventing breakage during cooking. Additionally, it reduces oil absorption by forming a protective film around the fried dough, which lowers the oil uptake rate during frying. The water retention properties of CMC also extend the shelf life of non-fried noodles (such as wet noodles) and help prevent noodle adhesion.

Beyond instant noodles, various convenient foods also contain CMC. These include instant soup/sauce packets, self-heating rice/instant congee, frozen convenience foods, among others.

In fast food soup/sauce packets, CMC ensures an even distribution of dehydrated vegetables and spices within the soup while preventing sedimentation. It can also enhance viscosity, providing sauces (such as curry sauce or tomato sauce) with a smooth texture—similar to that found in common cup fast food soups containing CMC.

In self-heating rice and instant congee products, CMC helps delay starch retrogradation in rice/congee to maintain a soft texture while preventing drying and hardening during storage. For instance, certain self-heating rice products incorporate CMC to prolong their shelf life.

For semi-finished products such as frozen buns, carboxymethyl cellulose (CMC) effectively mitigates the damage to dough caused by water crystallization during the freezing process, thereby preventing cracking upon thawing. Additionally, it helps maintain the elasticity of the dough even after heating.

In plant-based convenience foods, CMC facilitates the formation of fibrous structures in plant proteins, enhancing the chewiness of vegetarian meat alternatives. It is also utilized to stabilize these products' form and prevent ready-to-eat vegetarian items from becoming loose after heating.

In seasoning powders, CMC serves multiple functions: it prevents clumping, promotes rapid dissolution, offers cost-effectiveness, and demonstrates strong compatibility with other ingredients.

In summary, CMC is extensively employed in the food industry and stands out as an indispensable "partner" within this sector.
