Inorganic rice (1.44 g/100 grains) showed significant higher (P0.05) 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 (P0.05) in protein lipid and amylose content than organic rice.

Abstract

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 (P0.05) 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 (P0.05) 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 (P0.05) 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.
