Tianjin Longchang Food Chemical Research Institute is the first one who works on fat chemical decolorizing and bleaching, and it as well is the sole supplier of fat chemical decolourant and bleacher which called RS-A fat purificant.
The company handles with the research and development of fat purifying technology. The development on strong chemical decolourant RS-A fat purificant has already succeed and it has already been in production. This is a solid foundation for chemical decolorizing technique. The technique is based on chemical decolorizing and bleaching, comparing with the decolorizing and bleaching from adsorbed carclazyte and activated carbon material, it is without any non-biodegradable waste residue which could be pollution to the environment. The advantage of RS-A is that it could process without absorbing fat, carrying fat and wasting fat which are the defects of absorbed materials.
