 In: Journal of Root CropsSummary: Se empaco AY fresco en diversos tipos de empaque convencional (recipientes plasticos, bolsas de papel, recipientes metalicos, bolsas de polietileno de baja densidad (BPBD), bolsas de polietileno de alta densidad (BPAD), bolsas de yute y bolsas de yute impregnadas con politeno) para evaluar su eficacia de conservacion de la calidad. El contenido se analizo periodicamente hasta los 180 dias por CH, viscosidad, recuento microbiano total y poblacion bacteriana y fungica viable. Hubo solo un leve aumento en el CH del AY almacenado en BPAD, en las bolsas impregnadas con politeno y en los recipientes metalicos (0.52, 0.83 y 1.27 por ciento en 180 dias). El deterioro de la viscosidad fue mas rapido en el AY almacenado en bolsas de yute (inferior a 44 s Redwood a 60 dias) y menor en el AY almacenado en recipientes metalicos (44 s Redwood a 180 dias). Las BPAD y las bolsas impregnadas con politeno mostraron el menor vestigio de carga microbiana. (RA-CIAT)Summary: Fresh cassava starch was packed in various conventional package profiles (plastic jars, paper bags, metal containers, low-density polyethylene bags (LDPE), high-density polyethylene bags (HDPE), jute bags, and polythene-impregnated jute bags) to test their efficacy in preserving its quality. Contents were periodically analyzed up to 180 days for MC, viscosity, total microbial count, and viable bacterial and fungal population. There was only a small increase in the MC of starch in HDPE, polythene-impregnated bags, and metal containers (0.52, 0.83, and 1.27 percent in 180 days). Viscosity deterioration was fastest for the starch in jute bags (below 44 s Redwood in 60 days) and the least for starch stored in metal containers (44 s Redwood at 180 days). HDPE and polythene- impregnated bags showed the lowest trace of microbial load. (AS)
