Brazil is one of the largest mango producers and exporters, and Tommy Atkins mango is currently the most produced variety in Brazil. Multivariate analysis refers to statistical methods that simultaneously analyze multiple measurements on each individual or object under investigation and the Pareto diagram allows to verify the sensitivity of the studied parameters on the response of interest. Thus, the objective of this work was to statistically determine the best condition regarding cut type, storage temperature and concentration of microbial growth inhibitors for minimal processing of Mangifera indica L. pulp for better nutritional quality and process efficiency. The mangoes were purchased from the local Garanhuns-PE trade. They were washed in running water, sanitized with 100 ppm sodium hypochlorite solution; peeled with stainless steel knives and then samples were prepared from three different cuts for later identification of the best cut and given to these samples pre-selected treatments in schedule 24. The cuts were immersed in the solution of ascorbic acid and calcium chloride. They were then packaged in clear polyethylene lids and stored under refrigeration to determine the best temperature for eight days of storage in duplicate. The analyzes were: moisture content, fresh mass loss, total soluble solids, pH, total titratable acidity, water activity, sugars and color. All analyzes were performed according to the methodologies described by Maldonade, Carvalho and Ferreira (2013) and Instituto Adolfo Lutz (2008). To identify which variables influence the minimum processing, the Statistic® 7.0 software was used. The results processed by the computer program were represented in Pareto gr. From the statistical analysis it was possible to observe that the factors cut, temperature, concentration of the ascorbic acid solution and concentration of the solution of calcium chloride provided alterations in the conservation in the nutritional value and the quality by the parameters humidity and color, where there was significance in the effects. and interaction, with the best results for cut 1, temperature 2 ° C, and 2% concentration of inhibitors. Given the best conditions verified with the help of Pareto graphs were the conditions of values of the variables: temperature 2 ° C; cut 1 (slices approximately (0.5 x 8.0 x 2.0 cm) and, concentration of 2% ascorbic acid and 2% calcium chloride.
