Encapsulation of natural dye by Cyclodextrin : effect of Cyclodextrin types and concentration

Nowadays, cyclodextrin widely used in industries due to its ability in encapsulation process with natural dye. However, the production cost for cyclodextrin is very expensive. A study on how to reduce the production cost by optimization of pH, concentration of cyclodextrin and temperature effect on...

As a conclusion, this study was successful to increase encapsulation of natural dye by cyclodextrin production, reduce the energy consumption and also be able to reduce the production cost of cyclodextrin. 2010 Research Report NonPeerReviewed pdf en http://umpir.ump.edu.my/id/eprint/36489/1/Encapsulation%20of%20natural%20dye%20by%20Cyclodextrin.wm.pdf Che Man, Rohaida and Abdul Munaim, Mimi Sakinah and Zularisam, A.

A study on how to reduce the production cost by optimization of pH, concentration of cyclodextrin and temperature effect on encapsulation of natural dye by cyclodextrin using Response Surface Methodology (RSM) was successfully done.

All the parameter ranges obtained were used in RSM. RSM software in Design Expert version 6.0.8 was used with Central Composite Design (CCD) mode.
