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: In the removal and the concentration of the product, the most preferred methods are membrane separation processes. Despite the advantages, there are limitations with membrane separations; such as loss of their activities in harsh conditions or not sufficiently effective or too expensive or difficult to scale up. To overcome these limitations, Liquid emulsion membranes (LEM), which has the potential advantages of having selectivity higher than those attainable by current separation methods, saving on energy costs for final concentration of separated product, was chosen. Two kinds of LEM experiments are carried out here. First; deals with de-alcoholizing a solution using liquid emulsion membranes, due to its simplicity in design and operation and retains normal character of the feed solution. Effects of various parameters on the de-aloholization rate were studied in detail. Extraction of alcohol from real solutions like Anthocyanin extract solution and simulated pineapple wine has been carried out. Second; extraction of organic acids from dilute solutions using LEM by tailoring the emulsion composition for the purpose, the effect of various parameters on extraction has been thoroughly studied. The extraction results have varied with different parameters. This work traces the development of LEMs, discusses their key features, advantages and limitations, and explains with experimentation how the LEM can be best used by optimizing its conditions to maximize its extraction. Describes methods of modeling LEM systems and highlights some applications with industrial potential. The optimum operating conditions for the extraction of alcohol and organic acids are evaluated experimentally.
