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:	Thesis (Masters)
Additional Information:	It is easy to appreciate that food processing involves several unit operations and unit processes. They in turn involve heat, mass and momentum transfers, collectively known as transport phenomena. These transfer processes occur simultaneously in different unit operations and processes involved in food processing. Further, they influence each other significantly, the food being for human consumption the rates of these transfer processes need to be hastened in order to reduce the damage to the food quality during processing. Despite the effectiveness of traditional technologies from a microbial safety standpoint, they cause nutritional and sensorial food deterioration. Research in novel technologies for foods, for applications to various unit operations, often focuses on areas such as the assessment of processing time, the evaluation of heating uniformity, the appraisal of the impact on quality attributes of the final product as well as the prediction of the energy efficiency of these heating processes. Application of external fields has been demonstrated to be one of the most effective ways of achieving this objective. External fields have been gaining increasing recognitions in the food and bioprocessing industries as they improve the process and provide better energy and/or process efficiencies by modifying or adding additional driving force for the transport mechanisms involved. The food processing industry has been in look out for technically feasible and economically viable technology that has been proven thoroughly reliable in large-scale or long-term use. Scale-up and adopting for a continuous processing have still some issues that need to be addressed. Once this is achieved, the application of such external fields will find wider applications, adaptation and appreciation in food processing industry.
