Obtenção de massa de mandioca com adição de maltodextrina de amido de milho Waxy

Abstract

Este trabalho teve como objetivo o desenvolvimento de uma massa alimentícia produzida a partir de mandioca cozida para utilização em diversos fins culinários. Foram investigadas as características sensoriais, químicas e microbiológicas dessa massa alimentícia de mandioca e também parâmetros que interferem na vida de prateleira do produto final. A variedade de mandioca foi a IAC 576-70, classificada como de mesa, colhida com idade fisiológica de 14 meses e estocada por 24 horas. Em seguida as raízes foram descascadas, cortadas em toletes e retirado o cordão central nas raízes. Foram colocadas em alto clave a 100ºC por 40 minutos e em seguidas moídas onde receberam adição de maltodextrina de amido de milho waxy 0, 5, 10 e 15%, para a diminuição da retrogradação e adição de ácido cítrico a 1% no controle da contaminação microbiológica. As amostras foram acondicionadas em embalagens de polietileno e armazenadas a temperatura refrigerada (10ºC ± 0,5 ºC) e em temperatura ambiente, para análises físico, químicas e microbiológicas. Os lotes de amostras foram produzidos em triplicatas com 7 períodos de avaliações (0, 2, 4, 6, 8, 10 e 12). Houve diferenças estatisticamente significativas (p≤0,01) tanto em relação ao tempo como ao armazenamento para os teores de açúcar redutor, acidez titulável e textura, e os teores de umidade e pH não variável significativamente. O tratamento com adição de maltodextrina a 15% apresentou o melhor resultado contra o aumento da textura. O comportamento destes fatores durante a vida de prateleira não afetou os parâmetros sensoriais avaliados em produtos culinários da massa (purê e mandioca frita). Não ocorreu sinérese nas amostras. Aos sete DAP (dias após o preparo), a contaminação microbiológica na condição ambiente foi visualmente 2 alta, sendo descartado esse lote. O lote em condição refrigerado seguiu suas avaliações até o 14º DAP.

This work had as objective the development of a nutritious mass produced starting from cooked cassava for use in the several ends culinary. Were investigated the sensorial characteristics, physics chemistries and microbiological this foodstuffs mass of cassava and also parameters that interfere in the shelf life of the finish product. The cassava variety was IAC 576-70, classified as of table, picked with physiologic age of 14 months and stocked by 24 hours and soon afterwards they were peeled, cut in thole and withdraw central cord in the roots. They were put in high key to 100ºC for 40 minutes and soon afterwards ground where received treatments with addition of maltodextrina of starch of corn waxy 0 were, 5, 10 and 15%, and citric acid addition to 1% that searched for to reduce the retrogradação and to control the contamination microbiological. The samples were conditioned in packings of polyethylene and stored the refrigerated temperature (10ºC ± 0,5 ºC) and in room atmosphere. The lots of samples were produced in triplicates with 7 periods of evaluations (0, 2, 4, 6, 8, 10 and 12). There were significant differences statistically (p≤0,01) so much in relation to the time as to the storage for the tenors of sugar reducer, acidity titulável and texture, and the humidity tenors and pH they stayed unaffected. The treatment with maltodextrina addition to 15% presented the best result against the increase of the texture. The behavior of these factors during the shelf life didn't affect the appraised sensorial parameters in culinary products of the mass (purée and fried cassava). It didn't happen syneresis in the samples. To seven DAP (days after the preparation), the contamination microbiological in the environment condition was visually high, being discarded this lot. The lot in condition refrigerated followed their evaluations until 14th DAP.
