Duration:60 minutes


Consistent quality control measurements are key to high-quality food products, but variability in operator technique limits consistent results. Even though manual titrations are used throughout the food industry for fast quality checks of everything from raw ingredients to final packaged products, subjective endpoint detection limits the consistency of these measurements. This challenge makes it nearly impossible for two operators to record the same endpoint and deliver consistent results. Fortunately, there is a simple solution.



Dr. David Cunningham, senior principle scientist at Ocean Spray Cranberries, will share his improvements gained from automatic titration during his 30+ years of food industry experience. David drove improvements in product quality and productivity as he led an organizational change from manual to automatic titration in both research and production. As the principle lead for Ocean Spray’s technical support and training, David will also discuss the necessity of integrating a simple, easy-to-train automatic titration system.


Key learning objectives:


  • Understand how inconsistent measurements from manual titration negatively affect product quality
  • See how automatic titration overcomes the limitations of manual titrations while maintaining easy-to-use and easy-to-learn methods
  • Learn the productivity and accuracy benefits that come from using automatic titration in any quality control setting
