The greatest need for convenience products, easy to prepare, driven by new lifestyle and also the invasion of shelves for foreign products of high quality and diversification, have been modifying the traditional consumer of food. The aim of this study was to obtain shrimp powder by applying the spray dryer process, and to determine their chemical composition, physical and chemical characteristics, to study the stability of the packaged product in two types of packaging (laminated polyethylene) with and without vacuum and stored for a period of 120 days and still apply the shrimp powder in snacks formulation also its chemical composition, physical characteristics and sensory evaluation. The results showed that it is unnecessary to use adjuvants in the drying dehydration of the shrimps in spray dryer, which can be perfectly dehydrated at 120 ° C inlet air temperature. The powdered shrimp showed a satisfactory nutritional value with a high protein content and low fat content and a substantial source of minerals. The study of the stability has observed that the use of vacuum do not freak total effect on the product except as regards to lipid oxidation, departure counter there is a significant difference between the packaging, the packaging laminate having the most effective in maintaining activity water and moisture. The shrimp powder contributed to increasing the nutritional value of the snack, especially in regard to the protein content and minerals. The drying process in spray dryer in the conditions stipulated in this study were efficient in getting the shrimp powder with nutritional and physicochemical quality characteristics that favor its use in snacks formulation.
