Radio Frequency Assisted Extraction of Phenolic Compounds from Apple Peel
PhD Defense of Yanti Maslina Binti Mohd Jusoh, Bioresource Engineering
The work presented in this thesis is the step by step approach taken in the effort of developing radio frequency (RF) heating technology for the extraction of apple peel phenolic compounds. The work that has been carried out covers the design of an extraction system, the establishment of the initial extraction conditions, characterization of suitable solvents for the extraction system, process optimization and justification study.
In evaluating the suitability of this technology for extraction, a full laboratory scale RF heating system for nutraceutical extraction was conceptualized and constructed. Special emphasis was given to the design of the applicator as this aspect significantly influenced the efficiency of heat generation and distribution in the system. The function of each component, the importance and advantages of this design were reported.
