Abstract


Paprika obtained through the traditional process, from fruits dried in oak ovens, is stored at room temperature for 18 months. Samples are taken at 2-3 months time intervals and color quantity is evaluated, measuring it as ASTA units and carotenoid content. Values obtained from both measurements are compared, achieving a good correlation between ASTA units and total carotenoid content. As a result two equations are proposed, one linking both parameters and another which predicts the remaining ASTA unit as a function of storage time. ASTA values after 18 months of storing time are ca. 55 % of the initial values.
