Usage:
CMC is used as stablizing of acid drink due to its unusual characteristics and superior quality.It has following characteristics:
Prevent protein in acid milk from condensing,settling and laminating.
Due to its unusual smooth sugar paste state softer it dissolves,it makes drink taste good and smooth.
Its good evenness and acid resistance provides drink with excellent stability.
Furthermore,CMC is used in ice cream to make water,sebum,protein to form a mixture which is stable and well dipersed.At the same time,it tastes good,smooth and has good formability.
Used in bread and cakes,CMC can control paste viscosity and strengthen water taking and keeping.
