Tomato 101 Presentations


Description of Tomato 101

This presentation covers basic to detailed tomato processing concepts from field to final product. 

I tailor the presentation to my audience:  Plant employees, Plant managers, Maintenance, Supervisors, QA, R&D, Product Development, Engineering, Marketing, Operations, Purchasing, and companies selling to the tomato industry.

I use easy to understand terms, photos and videos, and interesting demonstrations.

I will travel to your location, bring my laptop loaded with the presentation, demos to help explain concepts, and the entire presentation copied in color and placed in 3-ring binders.

Sample of topics covered: How is tomato paste made, how are tomatoes peeled, how are tomatoes diced, what is paste finish? Hot break and cold break, what does that mean and how does it affect my products? How does an evaporator work in simple terms? How do you read mold, Brix, color, pH, drained weight? How is spoilage detected?

Tomato terminology explained.

I also offer a more in depth look at tomato processing systems titled Tomato 201.

I retired as a Director at Campbell Soup Company in 2006 after 36 years in the food industry. I started Tomato 101 in 2006, and consult for several food and equipment supply companies.

My career started at Campbell Soup as a chemist in quality control, eventually being promoted to QC Manager before switching to Operations. I was a tomato paste plant manager and started Campbell's aseptic tank farm and rail car delivery system.

I left Campbell's as Assistant to the Plant Manager, worked three years at T.H. Richards, a fruit and tomato processor, and worked one year at American Home Foods before returning to Campbell Soup in 1984 to run their new Tomato Processing Research Group. Years later I transferred to the Commercialization and Improvement Group in charge of tomato ingredients, tomato products processing, and new technology.

I was Chairman of the Tomato Processing Research Committee for 5 years for California League of Food Processors (CLFP), and currently I am Affiliate Member of CLFP.

I coauthored and presented CLFP's successful Tomato Processing School for 5 years.

Some of my clients include

J.G. Boswell Tomato Company

Reckitt Benckiser

Pacific Coast Producers

Ingomar Packing Company

Del Monte Corporation


Assan Foods

Aran Packaging
