Influence of handling and processing of rough rice on fissures and head rice yields

A Polymer Science Approach to Physico-Chemical Characterization and Processing of Pulse Seeds

“…The effect of drying temperature on the handling quality of whole seeds in terms of seed breakage upon handling has been investigated (Tang et al, 1990), however little work has been done on the effect of drying temperature on the milling quality of red lentils. Alternatively, a large amount of work has been performed in the area of understanding the effect of drying temperature on rice milling quality (Cao et al, 2004;Cnossen & Siebenmorgen, 2000;Cnossen et al, 2003;Iguaz et al, 2006). The rice industry cites breakage of rice kernels during milling as one of its main problems (Iguaz et al, 2006).…”

The rice industry cites breakage of rice kernels during milling as one of its main problems (Iguaz et al, 2006). Rice must be dried to 12-13% moisture content for safe storage.…”

“…Since most red lentils are dehulled before consumption, dehulling efficiency (yield of dehulled seeds) of red lentil is very important (Ross et al, 2010c;Vandenberg & Bruce, 2008;Wang, 2005). The rice industry cites breakage of rice kernels during milling/dehulling as one of its main problems (Iguaz et al, 2006). A large amount of work has been performed in the area of understanding the effect of drying temperature on rice milling quality (Cao et al, 2004;Cnossen et al, 2003;Cnossen & Siebenmorgen, 2000;Iguaz et al, 2006).…”

The concept of the glass transition has been used to explain rice kernel fissure formation during drying and subsequent breakage during milling of rice (Siebenmorgen et al, 2004).…”

Comparison of mathematical models to predict glass transition temperature of rice (cultivar IRGA 424) measured by dynamic mechanical analysis

“…Understanding the effect of MCGs, as well as temperature gradients, on rice fissure formation is important in controlling and optimizing drying and tempering conditions. This can be explained taking the glass transition temperature (Tg) of rice into account (Cnossen, Siebenmorgen, Yang, & Bautista, 2001; Cnossen, Siebenmorgen, & Yang, 2002; Cnossen, Jimenez, & Siebenmorgen, 2003; Cnossen, Siebenmorgen, Yang, & Bautista, 2001; Ghasem, Sadeghi & Miree, 1960; Iguaz, Rodriguez, & Virseda, 2006; Yang, Jia, Siebenmorgen, Howell, & Cnossen, 2002; Yang & Jia, 2003, 2004; Yang et al., 2005). Tg can be defined as the temperature at which an amorphous system changes from the glassy to the rubbery state and vice versa.…”
