With a duration of 120 days. According to bibliographic data obtained, we conducted a literature review of the vegetable (squash), it was used for raw material quality characteristics. For the development of this work, a design factory A x B x C with eight treatments and three replicates, the statistical test used was Tukey at 5% probability. Study factors were: A (state of maturity of the pumpkin), B (drying temperature), C (drying time). The variables analyzed were: sensory analysis in the pumpkin (color, smell and appearance), physical - chemical analysis in the flour (moisture, ash, protein, fat, fiber, pH, acidity and brix) and material balance for the best treatment provided by the response of the physical and chemical analysis. During the process of flour, made the respective reception and selection of raw materials, followed by washing and disinfection, then proceeded to peel, weighed, sliced, dried, crushed, pulverized, packed, labeled and stored. Having obtained the pumpkin flour, samples were sent to perform physical-chemical laboratories AGROLAB of Santo Domingo and Basic Chemistry Quevedo State Technical University. The results obtained in this study permitted the identification of treatment No. 2 (pumpkin mature x 60 º C x 24h) as the best, because he obtained better results in physical and chemical analysis. ..... |
