14:30-15:00 Safe thermal processes - 100 years and counting
In the first twenty years of the twentieth century, there were significant scientific developments in the area of thermal processing reported in the literature and applied in practice. These concepts have been refined over the past 100 years as scientific and computational methods have evolved; however, interestingly many of the concepts and data reported in that era are still very relevant to our work today as thermal processing specialists.

This presentation will attempt to highlight the basis and significance of understanding the kinetics of microbial destruction. Particularly as they apply to General Method calculations used to describe and predict them in both in-container and aseptic processing methods utilized to achieve commercial sterility.
Ian Britt, Institute For Thermal Processing Specialists (IFTPS), USA/Canada

15:30-15:55 Challenges faced by a vegetable canner
Antoine will be looking at the main 3 Challenges faced by a vegetable canner including how to ensure sanitary quality, product quality validation and the consumer assessment.
Antoine Cazier, Bonduelle, France
16:00-16:25 A review of the causes of spoilage in canned food in South Africa over a 20 year period
Canning is arguably the best way of preserving food. Almost one billion cans of food are produced and consumed worldwide each year. Although the food safety record of the canning industry is excellent, however, there are from time to time, spoilage incidents. Canned foods are safe and shelf-stable at ambient temperature due to heat inactivation of all vegetative microorganisms and the inactivation and / or control of spores. Good Manufacturing Practices include various quality control measures for managing the pathogen risk related to surviving mesophilic bacterial spores, as well as post processing contamination by a variety of organisms.

Nampak R&D have been assisting canneries solve and overcome their spoilage problems for the past 73 years. We are in a unique situation to be able to examine a broad range of canned foods processed in a diverse variety of canneries. We are in an exclusive position to be able to identify the most common pitfalls experienced by canneries; and how offer solutions on how to overcome them.

In this study we summarize the many causes of non-stability of canned foods over the past 20 years.
Susan Featherstone, SAFE-FOOD Consulting, South Africa

David Whittaker, Campden BRI
14:40-15:10 Comfort break
15:10-15:35 Thermal processing for challenging products
Ball widget cans: Is product entrapped in the widget insulated from the thermal process?
Ball Corporation has introduced the new “widget can” for the beverage industry, where a small plastic cylinder (“widget”) is installed onto the inside bottom of a typical beverage can. The design and function of the widget can assumes nitrogen gas will be trapped (“activated”) into the widget after product filling, nitrogen dosing, can sealing, and inverting of the can.

However, there is also an opportunity for product to become entrapped inside the widget during regular production. For this reason, the question has been raised if the plastic widget provides insulation during the thermal process to any entrapped product inside the widget. TechniCAL collaborated with Ball Packaging to study this condition in order to determine if entrapped product in the widget is insulated from the retort process. And if so, what considerations should process authorities take into account when establishing thermal processes for coffee-based Ready To Drink beverage products in the Ball Widget Can.
Scott Cabes, TechniCAL, USA
15:40-16:15 Process validation techniques using micro-organisms
Rob Limburn, Campden BRI
