The objectives of this research was to study the physical quality of grain and rice, milling quality, and its physicochemical properties of several local glutinous rice. The research materials were obtained from local farmer in West Java. The analysis was conducted at the Rice Quality Laboratory at Indonesian Center for Rice Research (ICRR), Sukamandi, West Java. There are differences in physical quality of grain and rice, milled quality and rice protein content of several local glutinous rice. Based on the Indonesian National Standard quality of paddy (1993), the empty grain of the four types of local glutinous rice did not meet the quality of III (maximum 3%). Based on the components of immature+chalky grain quality, the four types of glutinous rice locally meet the quality of I (maximum 1%). The rice length and the shape of the five types of glutinous rice consecutively are medium (5.51 - 6.60 mm) and medium (2.1 - 3.0). The yield of brown rice of four types of glutinous rice ranged from 76.73% (Ketan Pulut) to 79.91% (Ketan Nangka). The rice yield of four types of glutinous rice ranged from 64.57% (Ketan Pecut) to 69.63% (Ketan Bilatung). The range of five sticky rice varieties ranged from 6.41 to 9.63%, which include very low amylose classification (2-19%). The gel consistency and gelatinizing temperature of five glutinous rice are soft and low consecutively.
