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.

| Additional Information: | Among the various dehydration techniques, OSMOTIC DEHYDRATION has received considerable attention due to the low temperature and energy requirements in addition to better retention of the initial nutritional values in the final product. Osmotic dehydration is a process that partially removes water from the material through soaking in a hypertonic solution. Potato samples of constant thickness were used for the experiment. Mass transfer rates during osmotic dehydration depend upon factors such as, temperature, concentration and agitation of the osmotic medium. The first part of the project was carried out to validate the same. Very few work has been carried out on potato in the field of pretreatment with electromagnetic waves such as Infrared and Microwave radiations .The second half of the project dealt with subjecting the samples to electromagnetic waves as a pretreatment method followed by osmotic dehydration. The effect of pretreatment on osmotic diffusion was observed. |
