A formal engineering degree is not required, but you will get more out of Cornell's Food Processing Unit Operations Certificate if you are comfortable with technical concepts and quantitative thinking.

The Food Processing Unit Operations Certificate program recommends general familiarity with chemistry, microbiology, physics, and calculus. That foundation helps you follow how and why processes work, and it supports the basic calculations you will practice for topics like microbial reduction targets, heating and cooling loads, separation performance, and filtration or membrane flux.

If you have been away from math or science for a while, many learners do well by budgeting a little extra time early on to refresh core concepts as they arise in the course examples.

You will spend dedicated time on nonthermal processing in Cornell's Food Processing Unit Operations Certificate, with a focus on how the technologies work, what equipment is involved, which products are best suited, and what limitations or trade-offs matter in commercial adoption.

You will evaluate high-pressure processing and pulsed electric fields, compare light-based approaches such as UV and pulsed light, and examine where irradiation and cold plasma can be used for microbial control, pest control, or surface and package treatment. Just as importantly, you’ll consider factors that influence real-world feasibility, including process parameters, product properties, regulatory constraints discussed in the course context, and consumer perception challenges that affect adoption.
