Effect of gamma irradiation on physical characteristics of Jordanian durum wheat and quality of semolina and lasagna products

摘要

This study was conducted to determine the effect of using varying gamma irradiation doses on the physiochemical and Theological properties of semolina and its products. Ash, protein and water content were not influenced with gamma irradiation, while falling number and fungi counts decreased with increasing irradiation dose. Irradiation adversely affected wet gluten at 5kGy dose. Dough stability was deteriorated vigorously with increasing irradiation dose. Sensory evaluation showed that lasagna produced from 0.25- and 1 kGy-irradiated semolina did not show any significant differences as compared with the control sample.
