- Abstract
- The effect of moisture content on the thermal properties of rice embryos was investigated using differential scanning calorimetry (DSC). A long grain hybrid rice variety (Jinyou 974) grown in Hunan Province of China was selected in this investigation. The temperature scanning tests were carried out from 20°C to 180°C at different heating rates from 2°C/min to 20°C/min. Consistently higher values of glass transition temperature (Tg) were measured when higher heating rates were used during DSC measurements at every set of moisture contents. The Tg values decreased from (65.28±0.38)°C to (31.08±0.26)°C with increase in moisture content from (10.7±0.3)% to (22.0±0.7)% (w/w). The analysis of variance and the regression analysis showed that both the linear function and Gordon Taylor model can adequately represent the variation of Tg with moisture content (R2 > 0.96).
