Abstract

Cassava is very potential crop grown on marginal lands. It has great productivity, which in Lampung , most of the cassava roots are used for tapioca production. PD Semangat Jaya is one of small scale tapioca industry at Lampung. This industry still uses traditional technology in processing the starch, and the properties of the starch have never been characterized. Therefore the objective of this study was to evaluate the physico-chemical properties of the starch produced by this industry. Based on its distance for settling during extraction process, the starch was categorized into three grades, Grade I, grade II and grade III. Parameters evaluated were, the starch pH, whiteness, moisture, ash, starch, and amylose contents, and pasting properties. The data obtained from three replications were analyzed analyzed descriptively. The results showed that the pH, whiteness, moisture, ash, starch, and amylose contents of starch grade I were 4.1; 77.1; 7,87%; 0.17%; 79.3%; and 34.96%. Whereas for grade II were 4,25; 75.1; 8,1%; 0,22%; 72.38%; and ; 34.97% . The similar contents for grade III were 4,1; 65.7; 8.04%; 0.27%; 77.08% and 31.47% . These results revealed that chemical contents analyzed were in compliance with SNI. For the pasting properties, it was found that the maximum viscosity for grade I, II and II were 968.5 BU; 831.5 BU; and 688.5 BU. The paste instability (breakdown) for grade I, II, and III were 614.5BU; 512 BU; and 327.5 BU. The setback viscosity for grade I, II, and III were 191 BU; 181 BU; and 91 BU. These indicated that the starch granules in each grade has different structure , different functionality and therefore further study is needed.
