There is nothing like the flavor of fruit juice whether freshly squeezed or made from concentrate to clench your thirst, except when it’s not 100 percent juice after all. As the following tech note, “Authenticity Assessment of Fruit Juices using LC-MS/MS and Metabolomic Data Processing,” (pgs.135-141) points out, such substances have become a likely target for fraud and adultery practice even though certain legislation measures dictate authenticity parameters.

Why should we care? Consumers love to buy fruit juice. In a report by New Scientist, Britain sells more than 800 million pounds per year, while the U.S. holds it stakes at $12 billion or 7.5 billion pounds. Important numbers since 16 out of 21 brands of orange juice sold in Britain contained false ingredients such as beet sugar.Download The Food Compendium >

The problem with existing methods, however, is they are limited to targeted approaches useful when testing one or a handful of adulterations and researchers need to cast a wider net to keep up with the numerous compounds being added to the products. Using LC-MS/MS techniques with the QTRAP® and TripleTOF® systems researchers were able to capture non-targeted results for proof of authenticity. Included in the application note are details right down to where the juices were purchased to sample prep and results.
