Interpretive Summary:

Technical Abstract: This presentation presents some work on separating, identifying and cataloging chiral compounds in citrus and their approximate ranges in various products. A dual oven GC-GC-MS system with a cryo-trapping transfer line was used with a pre-column and chiral analytical column. Samples from Brazil, Florida, California, and from different years, producers, and varieties is presented. There are differences in the enantiomeric ratios between the various products. Additionally, the ratio of enantiomers are a used as a method to determine adulteration of products. This presentation is a continuation from last year’s presentation.
