Ultraviolet Light Processing for Foods 3 Part Course
Presenter: Dr. Tatiana Koutchma[bio]
Description: Application of ultraviolet (UV) light for water and air disinfection accounts almost 100 years of history whereas UV is in emerging phase for food treatment. The key drivers for interest in application of UV light treatments for foods have been due to its non-thermal and non-chemical character that allows achieving a safe product with excellent quality and extended shelf-life. Additionally, existing regulatory approvals from the US FDA and Health Canada provided advantages for the faster commercialization of UV processing. As a result, UV light has been taking its niche for processing fluid foods, drinks and beverages. The main interest includes its application as a preservation method for juice, wine and beer products, milk and dairy beverages, liquid eggs and variety of other soft drinks or heat sensible fluids to control microbial safety or to extend shelf-life.Innovative research of UV light for fluid processing applications has grown worldwide aiming to overcome challenges of high UV light absorption and improve efficacy of treatment and generated new knowledge in this area. This also includes growing number of studies for achieving more sustainable food production through novel UV processes that indicated the potential of UV technology in reducing the carbon footprint as a result of less energy used for processing and water savings.These on-line presentations aim to describe the state of the art of UV light technology for foods and consists of 3 separate iClasses.
Learning Objectives: iClass 1: Fundamentals OF UV Light, focuses on fundamental principles and features of food treatments using UV light. Optical behaviour and other food properties that are essential in process design are reviewed, along with the mechanism of microbial inactivation and variation in UV microbial resistance. Additionally, the focus will be made on critical process parameters and approaches to define and evaluate UV energy, fluence and dose.
