      enriched foods using mercaptopropionic acid-capped CdTe quantum dots.

AB  - Hydroxytyrosol (HXT) has been reported to have beneficial effects for human 
      health, such as antioxidant and antimicrobial properties and an important 
      contribution to the prevention of cardiovascular disease. Hence, exhaustive 
      research is currently being performed to prepare functional foods, such as tomato 
      juice or milk, with HXT. This paper presents a multi-commutated flow method based 
      on the quenching effect that HXT has on the fluorescence of water-soluble 
      mercaptopropionic acid-capped CdTe quantum dots. Under optimal conditions a 
      linear working range was obtained for concentrations between 10 and 250 ng microl(-)(1). 
      In order to demonstrate the suitability of the proposed method for the 
      determination of HXT, HXT-enriched samples were prepared. Using a QuEChERS 
      (quick, easy, cheap, effective, rugged and safe) procedure for extraction, HXT 
      was determined in the prepared functional foods (milk, infant formula, tomato 
      juice and tomato soup). Recoveries of 100% +/- 8%, relative standard deviations 
      (RSDs) lower than 5% and high sample throughput of 70 samples per h show the 
      potential of the system for the analysis of HXT in food samples.
