Florida—Research—Juicier Shrimp


When you eat a shrimp, you probably want it to be juicy. That’s why University of Florida Institute of Food and Agricultural Sciences researchers are trying to find alternatives to phosphates to lock in that texture and savory flavor.


Normally, phosphate or table salt is used to retain moisture in meat and seafood, said Paul Sarnoski, a UF/IFAS assistant professor of food science and human nutrition.  But adding salt to the food puts more salt in a person’s diet, and that’s unhealthy, Sarnoski said.  Additionally, phosphates are relatively expensive, he said.


In a study recently published in the Journal of Food Science, Sarnoski and his UF/IFAS colleagues found that phosphate alternatives such as polysaccharides—a type of carbohydrate often used as a food additive—can help retain water in shrimp.  UF/IFAS scientists tested the shrimp using phosphates and polysaccharides. They boiled, froze and dried the crustaceans to see how much water the shrimp lost.


 “The study showed there are some polysaccharides that will likely not change the way the shrimp tastes, feels or looks to the consumer,” Sarnoski said.  Researchers discovered this through taste tests by consumer panelists at the UF Center for Smell and Taste.


Polysaccharides are usually inexpensive, and in the long run, cost less for the food processor, restaurant operator— and theoretically, the consumer—than phosphates.
