A backgrounder for more information on citrus limonoids.
Symposium Highlights Potential Benefits of Citrus CompoundsBy Kathryn Barry Stelljes
March 23, 1999
ANAHEIM, Calif., Mar. 23--Natural chemicals in citrus fruit could lead to tastier juice and to other benefits for farmers, food processors and health-conscious consumers, according to researchers presenting findings at a special symposium of the American Chemical Society here today.
In 1972, California chemist Shin Hasegawa at USDAs Agricultural Research Service identified citrus compounds--called limonoid glucosides--that reduce the bitterness of the citrus juice. These compounds form naturally during ripening and can be extracted from seeds, pulp and other tissues left over after juice processing.
Since then," he said, "we have isolated 17 of these compounds and developed methods for producing them on a commercial scale. We have also isolated the enzyme responsible for the production of limonoid glucosides." Hasegawa is based at ARS' Western Regional Research Center in Albany, Calif.
Hasegawas team has collaborated with researchers in several countries who are investigating potential health benefits and other uses for the compounds. As examples, university scientists have preliminary findings indicating the chemicals may have anti-cancer and cholesterol-lowering properties.
Diverse research on these citrus compounds will be presented today in a day-long symposium at the American Chemical Societys 217th national meeting. This is the first time all of the research on limonoids has been pulled together in one place, said Hasegawa.
Scheduled topics for the symposium include:
