Effect of Processing Conditions on Physical Properties
Effect of Processing Conditions on Physical Properties of Parboiled Rice 107 ing at 80 and 90˚C, temperature of the steam was controlled by the combined action of the PID temperature controller and the relay switch through a thermocouple wire placed in the steam in the cooker between the sample holder and the water surface. The
Physicochemical properties, such as MC, adhesion and hardness, cooking time, energy consumption are induced by the processing conditions which affect the eating quality of rice. The stickiness of PBR decreases due to parboiling treatment and depends on the severity of treatment [ 49 , 102 – 104 ].
Impacts of parboiling conditions on quality
The parboiling process includes soaking, steaming, and drying, which all have impacts on the quality of parboiled rice. Parboiling decreases breakage susceptibility of rice during the dehulling and milling processes, resulting in greater head rice yield.

Effect of Processing Conditions on Color Change of Brown
The effects of the soaking and steaming steps in rice parboiling on color changes and the levels of reducing sugars in rice were studied. Brown rice was soaked to different moisture contents (MC, 15, 20, 25, and 30%).
A good linear relationship between the thermal property and cooking time clarified the cooking behavior of parboiled rice. A cooking time of 20 to 24min was obtained for the improved quality of parboiled rice produced at the processing conditions of 90°C-30min and 100°C-10min.
Effect of Processing Conditions on Cooking Qualities
A cooking time of 20 to 24min was obtained for the improved quality of parboiled rice produced at the processing conditions of 90°C-30min and 100°C-10min. It was assumed that for the respective cooking time, cooked under identical conditions, all parboiled rice might show the distinct level of solid contents.

Effect of ultra-high pressure on quality characteristics
Quality characteristics of parboiled rice pre-treated by ultra-high pressures (UHP, 100–600 MPa) were investigated in this study. The LF-NMR results and morphologies of parboiled rice grain showed that UHP treatment promoted uniform distribution of water in rice grain and effectively eliminated “white-core” grain.

Rice is the staple food for nearly two-thirds of the world’s population. Food components and environmental load of rice depends on the rice form that is resulted by different processing conditions. Brown rice (BR), germinated brown rice (GBR) and partially-milled rice (PMR) contains more health beneficial food components compared to the well milled rice (WMR).

Effect of Processing Conditions on Color Change of Brown
Linear regression analyses indicated that parboiling had a larger effect on ΔE of milled parboiled rice than of brown parboiled rice. Furthermore, the linear relationship between the level of gelatinized starch and ΔE of the milled parboiled rice samples showed that both parameters are indicators for the degree of parboiling. Reducing sugars were formed and lost during steaming, suggesting Maillard reactions during steaming.
