When Luz Inés Nieto enrolled in UC Davis Continuing and Professional Education’s Applied Sensory and Consumer Science Certificate Program, she was looking to deepen her expertise and grow in her field. Since completing the program, she has advanced her career at Griffith Foods—earning a promotion in 2022 and taking on expanded responsibilities in sensory science and consumer insights.

Nieto's love of discovering new flavors and understanding consumer perception is what led her to sensory science. 

“I have taken training on chili peppers to understand all the sensory differences between varieties and the flavors they add to dishes,” she said. “And being from Mexico, this is essential.”

In 2019, as a sensory coordinator with Griffith Foods in Monterrey Nuevo Leon, Mexico, Nieto's supervisor suggested UC Davis CPE's online sensory program to advance her skill set. 

“Talking with colleagues from other Griffith units, they highly recommended this certificate to me,” Nieto said.

Building Her Expertise

As an undergrad, Nieto studied as a chemistry bacteriologist and parasitologist, and that’s when her interest in food science developed. “I started working on quality in microbiology,” she said. But it became clear that she also needed to understand the consumer’s perspective, so she decided to learn about methods for testing whether products aligned with consumer desires.

When she was hired by Griffith in their sensory department, Nieto began taking courses to learn more about training panels and performing discriminative and consumer testing. 

Nieto’s most recent sensory education was the Applied Sensory and Consumer Science Certificate Program. Because it is designed for working professionals, the program provided her with practical skills and techniques she was able to apply directly to her current position. 

“The program has been very useful to me in helping me make better decisions with greater knowledge,” she said. “In addition to having improved planning in projects that need sensory science to obtain better results, the certificate helped me further understand each test and how to interact with other departments in my company—mainly quality, research and development, marketing and sales.”

Adapting Testing Methods in Remote Environments

Halfway through her certificate, COVID-19 hit, forcing Nieto to work from home. This created a radical shift in how she performed consumer tests. 

“We had to understand how to make kits and shipments to send to panelists’ homes,” she said. “I was able to apply what I learned in the program to carry out tests outside a laboratory.” 

Where Is She Now?

Since completing the program, Nieto has continued to grow in her career at Griffith Foods. In 2022, she was promoted to sensory manager, where she continues to apply the skills she gained through the program to drive data-informed decisions and enhance consumer experiences.
