Resumo
O objetivo deste estudo foi determinar o efeito do branqueamento e temperatura de fritura sobre a cor ea textura de fatias de mandioca variedade ICA-costeña durante a fritura por imersão. Antes de fritar, as fatias de mandioca (diâmetro: 35mm, espessura de 1,31mm) foram escaldados em água quente a 80°C por 4min. Fatias de mandioca unblanched foram utilizados como controle. A fritura foi realizada em óleo de palma a 140, 160 e 180°C até um teor de humidade final de cerca de 1,8g/100g (base húmida). A cor e textura foram medidos periodicamente durante a fritura. A cor é determinada pela Visão Computacional e força máxima de fratura normalizado (usado para modelar as mudanças de textura) foi medido em um analisador de textura Shimadzu EZ Test ®. A temperatura de fritura de forma significativa, muda a cor fatia de mandioca frito, embora estas modificações não afetam o branqueamento. A temperatura de fritura e branqueamento teve um efeito significativo (nível de significância de 5%) na textura final da fatia frito
