Statistically was worked whit a significance level of 5 percent, the treatment that present the best calcifications and physical-chemical conditions was T9 that contain 45percent of imported wheat flour and 55 percent of national wheat flour, with average percentages of hardness11,25 N, humidity 3,62 percent, sensory the cookies elaborated with T9 (45 percent IWF y 55 percent de NWF) were very crunchy (7,94), cookies were golden (2.83), of a characteristically cookie smell (4.07), a very nice savor(7,79) and that the consumer totally acceptation (8,8). In this study was determined the rheologic characteristics of the national wheat flour, the imported flour, the mixture of the best treatment T9 (45 percent IWF y 55 percent de NWF) and a commercial cookie flour “Santa Lucia”. We realize a bromatological analysis concluding that the salty cookies elaborated with the best treatment are appetizing complement of a diary alimentary ration that contribute an energetic value of 485,76 Kcal per 100g. The shelf life is 2.7 months in extreme conditions of temperature (30 percent) and humidity (70 percent RH). Finally, the cost of 30 g salty cookies packages in cellophane bags was 0,09 dollars and its yield of 97,03 percent.
