Distribution of phytic acid and mineral elements in three indica rice (Oryza sativa L.) cultivars

Losses of essential mineral nutrients by polishing of rice differ among genotypes due to contrasting grain hardness and mineral distribution

“…It is generally assumed that a substantial part of both Zn and Fe in the cereal grain is bound to phytate (Greffeuille et al, 2011;Mills et al, 2005;Simic et al, 2009). Up to 80% of the P content of cereal grain may be present in the form of phytate and losses of Zn and Fe during polishing would therefore be expected to match that of P (Wang et al, 2011). However, this was only true for Fe, where both the initial steep losses as a function of polishing time (Figs.…”

“…The differences in element distribution may to some extent reflect that of chelating ligands such as phytate (Liang et al, 2008;Persson et al, 2009;Wang et al, 2011) andproteins (GomezBecerra et al, 2010;Kutman et al, 2011) which also can affect the nutritional quality of rice in combination with polishing procedures. It is generally assumed that a substantial part of both Zn and Fe in the cereal grain is bound to phytate (Greffeuille et al, 2011;Mills et al, 2005;Simic et al, 2009).…”

Effect of puffing on physical and antioxidant properties of brown rice

“…Minerals are essential nutrients for human well-being and they play a vital role in the effective functioning of the body activity (Wang et al, 2011). Table 3 shows the level of minerals in raw, parboiled and expanded rice.…”

Mapping of Quantitative Trait Loci for Contents of Macro- and Microelements in Milled Rice (Oryza sativa L.)

“…6,11,23 These results are in accordance with the understanding that most of the mineral elements are concentrated in the outer part of the rice grain but Zn has an relatively even distribution. 12,13,25,26 For the remaining element tested in our study, Mn, no consensus could be achieved because the content in brown rice had a large variation ranging from 7.3 to 35.0 mg/kg. 6,8,11,22,23 Correlation coefficients between the contents of P, K, Ca, Mg, Mn, Zn, and Cu of the 243 RILs were all highly significant (p < 0.01), indicating the feasibility of improving these elements simultaneously in rice grain.…”
