UF Study: Consumers Like Shelved Tomato Juice More Than a Refrigerated Product
Tempted by the tangy taste of tomato juice? Consumers may prefer a product sold from grocery store shelves over a minimally pasteurized refrigerated product, but only by a small margin, new University of Florida research shows.
Researchers at the UF Institute of Food and Agricultural Sciences made four types of tomato juice, combining six UF/IFAS tomato varieties.
In this study, scientists wanted to know how heat treatments impact flavor compounds in tomato juices. Generally, more heat treatment gets rid of the fresh and fruity characteristics typically found in a high-quality fresh tomato purchased from the produce section of the grocery store, said Paul Sarnoski, a UF/IFAS associate professor of food science and human nutrition and lead author of the study.
In their attempts to see the degree to which consumers liked heat-treated tomato juice, researchers made two types of products. One was refrigerated and meant to be sold like fresh orange juice; the other was shelf-stable and would be sold unrefrigerated.
They then tested the tomato juices on about 600 people participating in consumer test panels at the UF Sensory Lab on the main campus in Gainesville. Scientists found that consumers preferred juice stored on shelves over refrigerated juice, by just a tad.
