fruit juice authenticity (1)


Here, a biomarker-free detection assay was developed using an optical nanosensor array to aid in the food safety of citrus juices.

Researchers have coupled machine learning capability of their computational process named algorithmically guided optical nanosensor selector (AGONS) with the fluorescence data collected using their nanosensor array, in a biomarker-free detection assay, to construct a predictive model for citrus juice authenticity. 

Over 707 measurements of pure and adulterated citrus juices were collected for prediction. Overall, the approach achieved above 90% accuracy on three data sets in discriminating three pure citrus fruit juices, artificially sweetened tangerine juice with various concentrations of corn syrup, and juice-to-juice dilution of orange juice using apple juice.
