Effects of fluidized bed drying temperature and tempering time on quality of waxy rice

Effect of high-temperature fluidized-bed drying on cooking, textural and digestive properties of waxy rice

“…The starch gelatinization of the sample dried at 90°C was 4.8% at 30-min tempering time and increased to 10.4% when the tempering time increased to 120 min; this result could improve the head rice quality (Jaiboon et al, 2009). At other drying temperatures, the dried waxy rice samples obtained at 120-min tempering time were not taken to determine their thermal properties since the head rice of the samples dried at such conditions was the same as that of the sample tempered for 30 min as reported by Jaiboon et al (2009). The waxy rice obtained by drying at 90°C and tempering for 120 min was therefore chosen for subsequent quality tests.…”

“…Such drying methods may nevertheless take long time. To enhance the drying rate, high-temperature drying is frequently used (Tirawanichakul et al, 2004;Prachayawarakorn et al, 2005;Jaiboon et al, 2009). However, high-temperature drying via an LSU dryer may not be appropriate for rice since a contact between grains and drying medium is generally poor.…”

Effects of inlet air temperature and spray rate of coating solution on quality attributes of turmeric extract coated rice using top-spray fluidized bed coating technique

“…The changes of such color parameters did not involve with the browning reactions. This is due to the fact that if it is involved with the browning reactions, the lightness should be decreased and the redness should be increased (Bhattacharya, 1996;Lamberts et al, 2006;Jaiboon et al, 2009). But, the changes of L ⁄ and a ⁄ in this case are possibly caused by the lower coating efficiency at higher inlet air temperature (Kage et al, 1996;Dewettinck and Huyghebaert, 1998).…”

“…The broken TCR in 200 g sample was separated using an indent cylinder separator (Satake, model TRG-05A, Hirochima, Japan) and the head coated rice was determined (Jaisut et al, 2008;Jaiboon et al, 2009). The broken TCR is defined as TCR that has the kernel length less than 75% of its original length.…”

Improving head rice yield of glutinous rice by novel parboiling process

“…for acceptable head rice yield. [17,19] Jaiboon et al [1] reported that fluidized bed drying can keep a high head rice yield of waxy rice when dried to its initial moisture content of 28.8% (d.b. )…”
