AB  - Crocin yellow was determined in soft drinks, sausages and sauces by ultra 
      performance liquid chromatography coupled with ultraviolet detector and analyzed 
      within 5 min using a short analytical column ACQUITY UPLC HSS T3 2.1 x 100 mm 1.8 
      mum) with gradient elution. An innovative pretreatment method based on homemade 
      macroporous resin solid-phase extraction (SPE) column was established. The SPE 
      column packed with macroporous resins could simplify the sample preparation of 
      multi-matrices and be reused by regeneration steps. The recoveries of crocin 
      yellow added to soft drinks, sausages and sauces at three levels ranged from 
      81.3% to 106.2%, and relative standard deviations (RSDs) were within 8.8%. The 
      limits of quantitation of soft drinks, sausages and sauces were 0.5 mg/kg, 5 
      mg/kg and 5 mg/kg, respectively.
