Effect of Modified Atmosphere Packaging (MAP) on the Moisture and Sensory Property of Saffron

Abstract

In this research, the effect of different Modified Atmosphere Packaging (MAP) and storage temperature was investigated on the moisture and sensorial properties of saffron under different conditions. Saffron samples were packed by using different combinations of CO2 and N2 including: MAP1 (100% N2), MAP2 (40% N2 + 60% CO2) and MAP3 (60% N2 + 40% CO2) and were stored at three different temperatures (4°C 25°C and 35°C) for 12 weeks. Moisture and sensorial properties of samples were evaluated every three weeks. The results revealed that the moisture of saffron samples were preserved more favourably with MAP1 than with MAP2 and MAP3. Regarding temperature, 4°C was the most efficient. Results of sensory evaluation indicated that MAP1 had a significant positive effect on the external appearance of saffron samples.
