title: Effect of storage conditions on sensory properties of Bierzo roasted pepper.
abstract: BACKGROUND
  Roasted pepper is marketed with the European recognition of Protected Geographical Indication 'Pimiento Asado del Bierzo'. The industry needs to prolong the period in which fresh pepper received from farmers is available to be processed, without deteriorating the sensory quality of roasted pepper. The objective of this study was to analyse how different storage conditions affect the sensory quality of roasted pepper.
  
  
  RESULTS
  Differences in weight loss among storage conditions did not affect roast yield. Descriptors juice quality, bitterness and spiciness were not influenced by storage conditions in 2006 or 2007, whereas uniformity, skin surface, cohesiveness and smokiness were influenced by storage conditions in both years. Overall quality was better when pepper was stored for 5 days at 18 °C or for 10 days at 8 °C.
  
  
  CONCLUSIONS
  The quality of roasted pepper was affected positively by storage conditions in terms of colour and uniformity, which were improved, and hardness, which was reduced. Newly roasted samples, on the other hand, obtained the lowest quality values. Therefore storage of pepper for up to 10 days was useful not only to extend the time of roasted pepper processing for companies but also to improve the sensory quality of roasted pepper without decreasing the roast yield of processed pepper.
