The present investigation highlights the feasibility of a polymer grafting process to enhance the durability and flame retardancy of rice straw towards application as a low cost roofing material. The success of this grafting methodology was perceived to depend upon a bi-step pre-treatment process encompassing delignification and inorganic salts dispersion. Subsequently free radical polymer graf...

Selenium, an essential micronutrient for humans, is insufficient in dietary intake for millions of people worldwide. Rice as the most popular staple food in the world is one of the dominant selenium (Se) sources for people. The distribution and translocation of Se from soil to grain were investigated in a Se-rich environment in this study. The Se levels in soils ranged widely from 0.5 to 47.7 m...

Rapid drying can increase brittleness and induce internal cracks which predispose the product to breakage during subsequent activities. The drying process must be understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. This study is to give a mathematical model with numerical solution to follow the mass distributi...

High-temperature stress degrades the grain quality of rice; nevertheless, the exogenous application of plant growth regulators (PGRs) might alleviate the negative effects of high temperatures. In the present study, we investigated the responses of rice grain quality to exogenously applied PGRs under high day temperatures (HDT) and high night temperatures (HNT) under controlled conditions. Four ...

(eds M.C.S. Wopereis et al.) 311 than white rice in Kumasi (the second largest city in Ghana), but this is not true for other markets in the country (Sakurai et al., 2006). Nigerians generally prefer cooked rice of a ‘harder’ texture than consumers in neighbouring countries. Watanabe et al. (2002a,b, 2006) showed that many grain quality characteristics such as grain breakage, grain whiteness af...

Inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. Since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to experimentally study them in specific large-scale apparatuses. In this research, the behavior of rockfill materials in two large rockfill dams co...

an understanding of the strength of rice grains as affected by moisture content and temperature is important for analysis and prediction of cracking and/or breakage behavior during handling and processing. further, the magnitude of these properties at various moisture contents and temperatures is needed for the accurate design of milling machinery so that grain damage is minimized. to determine...

We evaluated the influence of the main cereal of the diet and the degree of heat processing of rice on apparent ileal and total tract digestibility of nutrients and ileum morphology of pigs at 37 d of age. Control pigs were fed a complex diet that contained 500 g/kg cooked and flaked maize with a degree of starch gelatinisation (SG) of 840 g/kg. Experimental groups received the same complex die...

Parboiled rice is recognized for its greater milling yield and reduced breakage compared to raw during processing. Additionally, parboiled has better glycemic control numerous health benefits. However, the production of requires energy-intensive processing as well wastewater production. This study reviews rice, including condition, nutritional properties, potential use, emerging green technolog...

Native rice starch (NRS, amylose/28.9%) was gelatinized by improved extrusion cooking technology (IECT) and retrograded (RRS) after low temperature storage (4 °C). The retrogradation behaviour of RRS was changed to low retrogradation percentage and low retrogradation rate. The retrogradation resulted in a high compact morphology. The melt enthalpy change and percentage of retrogradation of RRS ...
