摘要

Abstract

Saffron is the most precious and expensive agricultural product.A dehydration treatment is necessary to convert Crocus sativus L.stigmas into saffron spice.To the best of our knowledge

no information on mass transfer parameters of saffron stigmas is available in the literature.This study aimed at investigating the moisture transfer parameters and quality attributes of saffron stigmas under infrared treatment at different temperatures (60

…

110℃).It was observed that the dehydration process of the samples occurred in a short accelerating rate period at the start followed by a falling rate period.The effective moisture diffusivity and convective mass transfer coefficient were determined by using the Dincer and Dost model.The diffusivity values varied from 1.1103×10

.The quality assessment results showed that the total crocin content increased

when the temperature increased up to 90℃ but

in higher tempe

ratures

the amount of crocin decreased slightly.The total safranal content of the samples decreased slightly when drying temperature increased from 60℃ to 70℃ and then continuously increased up to 110℃.Also

the amount of picrocrocin increased from 83.1 to 93.3 as the drying temperature increased from 60℃ to 100℃
