Abstract

This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page.

Item Type:	Student Project Report
Additional Information:	As a natural food colorant, betalains are finding increased importance. The presence of free sugars accelerates the degradation of betalains, and hence it is desirable to separate sugars from beet extract. Aqueous Two Phase extraction has been identified as an attractive technology for Downstream processing of betalains,mainly for the removal of sugars, as this method allows the integration of separation,concentration and partial purification in one step. The effect of different parameters like Tie-Line Length, phase volume ratio, and concentration of beet juice on the partitioning behavior of betalains was studied. The selective partitioning of betalains to the top and sugar to the bottom phases was observed during Aqueous Two Phase Extraction.
Uncontrolled Keywords:	Aqueous Two Phase Systems, Betalains, Downstream Processing, Liquid- Liquid Extraction, Partition Coefficient, Sugars, Differential Partitioning, Tie Lines.
