Abstract

Chemical composition and cooking quality of two sweet-potato cultivars were analyzed. Morada INTA and Rojo Blanco cultivars from Agricultural Experiment Station-INTA, San Pedro, province of Buenos Aires, Argentina (lAt 33°41'S., long 59° 41'W.), and from harvests of three different years, were used. Dry matter, free aminoacids, starch, reduced soluble sugars, total nitrogen, pectines, specific gravity, sucrose, total ashes, calcium, phosphorus, iron and magnesium were analyzed. Except for aminoacids and iron contents, the averages of Morada INTA parameters were statistically different at 5% probability level from those of Rojo Blanco. Sweet potatoes were also prepared as boiled and candied, and both products were evaluated by a pannel, using a hedonic scale of 5 points. No statistical differences were found between Morada INTA and Rojo Blanco cultivars. Therefore, Rojo Blanco can replace Morada INTA. The quality of the raw material for processing depends on the particular characteristics of the harvest of each year.
