Four different village level arrowroot starch processing systems were evaluated, namely: System A - crushing of the rhizomes using the "ilohan"; System B - grating of the rhizomes using the PRCRTC grater machine; System C - wet grinding of the chipped rhizomes to an attrition grinder; and System D - grinding of the dried chips (dry method of starch extraction). Results of the evaluation showed that grinding of dried chips produced the highest production of starch per man-hr operation (1.97 kg/man-hr), however, the method produced the lowest quality of the starch produced due to the high ash content (3.97 percent), high percentage of coarse particles (FM = 1.27), and poor brownish color. Grating of the rhizomes using the PRCRTC grater machine resulted in starch production of 1.47 kg/man-hr and was found to be the most efficient in terms of performance and quality of starch output. Relevant information regarding the processing of arrowroot starch at the village levels and factors affecting quality of starch produced were also presented.
