Abstract
Color of chips made from potatoes (Solanum tuberosum L.) subjected to handling treatments was darker than of non-handled tubers in nine of ten experiments. ‘Monona’ and ‘Rosa’ appeared to be more vulnerable to the adverse effects of handling than were ‘Kennebec’ and ‘Norchip,’ but all cultivars were affected. Levels of fructose and glucose were elevated by handling. Sucrose also increased in all cultivars except ‘Kennebec.’ The handling effect was most noticeable early (December) or late (March or April) in the storage season. The effect of chilling did not appear to be intensified by handling.
Resumen
En nueve, de un total de 10 experimentos, el color de las papas (Solanum tuberosum L.) expuestas a manipuleo, y fritas a la inglesa, fue más obscuro que el obtenido al procesar tubérculos no manipulados. ‘Monona’ y ‘Rosa’ se mostraron más vulnerables a los efectos adversos del manipuleo que ‘Kennebec’ y ‘Norchip’, pero en general todos los cultivares fueron afectados. Los niveles de fructosa y glucosa se vieron incrementados por el manipuleo. La sucrosa también se incrementó en todos los cultivares, con excepción de ‘Kennebec’. El efecto del manipuleo fue más notorio a comienzos (Diciembre) o al final (Marzo o Abril) de la temporada de almacenamiento. El efecto del enfriamiento pareció no intensificarse por el manipuleo.
