Physicochemical properties of organic and inorganic Phatthalung Sungyod rice
2012
Meenune, M. | Keawpeng, I.
Rice from different cultivation systems, organic and inorganic rice, were growth and harvested from Phatthalung province, the Southern Thailand. The difference in their physicochemical properties was determined. Inorganic rice (1.44 g/100 grains) showed significant higher (P<0.05) in rice grain weight compared with organic rice (1.42 g/100 grains). Different cultivation system has profound effects on physicochemical properties of rice. Inorganic rice showed significantly higher (P<0.05) in protein, lipid and amylose content than organic rice. Protein, lipid, amylose and anthocyanin content of organic rice were 5.64% (db), 2.48% (db), 15.32% (db) and 14.66 mg cyanidin-3-glucoside/100 g (db), respectively. Protein, lipid, amylose and anthocyanin content of inorganic rice were 7.02% (db), 2.59% (db), 16.27% (db) and 15.60 mg cyanidin-3-glucoside/100 g (db), respectively. Both of organic and inorganic rice showed type-A of X-ray diffraction pattern. In addition, the small difference in crystallinity of organic and inorganic rice was observed. The swelling power of organic and inorganic rice was 13.14 and 13.02 g/g (db), respectively. Peak viscosity of inorganic rice (118.62 RVU) is significant higher (P<0.05) than organic rice (116.88 RVU) when studied with RVA. The enthalpy of gelatinisation of organic and inorganic rice was 8.08 and 8.01 J/g, respectively.
