Video: Allpax conducts research project to improve pouch sterilization

Allpax put more than 15 food products packaged in various microwaveable pouches and bowls and tested them to identify package and product combinations that hold the most promise of quality and capacity improvements for brand owners.

Allpax Products, powered by Pro Mach, said today that the company is researching the impact of Gentle Motion agitation sterilization on more than 15 foods packaged in various microwaveable pouches and bowls. This research documents reductions in processing time, capacity increases compared to static retort processing, and the overall subjective improvements to quality, including taste, texture, and appearance. The company will discuss its findings with Pack Expo 2013 attendees in Las Vegas, September 23-25. (Allpax Booth C-2114)

Gentle Motion agitation is a high capacity retort process designed for pouches and bowls that are oriented horizontally in a retort rather than vertically as are cans, bottles, and jars. The back-and-forth motion of the retort baskets in a Gentle Motion retort produce waves of heat flowing longitudinally through such products as soups and sauces that have low-to-moderate viscosity and moderate-to-high liquid and particulate content.

Depending on the product being retorted, cycle time may be reduced from 5 to 40 percent. Less thermal load tends to improve the taste, texture, and appearance of shelf stable food. Each Gentle Motion retort can have up to six full-sized baskets and can be loaded and unloaded via an automated system.

“Our research is designed to identify the product and pouch or bowl combinations with the highest promise of capacity and quality improvement through Gentle Motion agitation,” said Greg Jacob, Vice President and General Manager, Allpax. “This effort will not only save brand owners a measure of R&D time, but will also indicate opportunities in terms of product enhancements and new product introductions.”

Allpax will be demonstrating at Pack Expo heat transfer capabilities of longitudinal agitation with its 2402 Multimode R&D retort, which is capable of more than 20 different retort modes.
