ABSTRACT The present investigation was carried out in the company AgroAndino S.R.L. Pertaining to the productive sector, this one is dedicated to the dehydration of fruit, being its main product the organic dehydrated aguaymanto, its main problem is the color change of the product since the company offers a “Golden Berry“ dehydrated of yellow orange color but many Sometimes takes a brown color, generating problems in the image and quality of product, on the other hand as the company is in growth requires the acquisition of a new furnace with the ideal conditions for the use of the technology thus increased its sales; The purpose of the present investigation was to determine the influence of temperature and relative humidity in the process of dehydration of the organic aguaymanto to optimize the nutritional load and the color of the product in the company AgroAndino SRL, having as hypothesis that Influence of temperature and relative humidity in dehydration process of the organic aguaymanto the nutritional value will increase and the brown color will change to yellow orange. The study was performed through drying tests, physical - chemical analysis and the collection of information through interviews, documentary analysis, observation guide and data collection. The nutritional load was measured by quantifying vitamin C and product color in terms of L *, a *, b * (brightness, hue and saturation). The information obtained was processed in Excel and a response surface modeling was performed using the Statgrafic Software, consolidating the results into tables and figures. An economic evaluation was also developed using the cost - benefit methodology. According to the results for vitamin C, the temperature significantly influences its optimization with a P-value less than 0.05 and an R2 of 99.9989%, as regards color for the L * and b * indicators, temperature and relative humidity Have a significant P-value of less than 0.05 and an R2 of 99.7826% for L * and 99.9724% for b *, as for indicator a *, only the temperature has a Pvalue of less than 0.05 with an R2 of 97.5471% . It was determined that the optimum dehydration temperature to achieve a lower vitamin C loss is 63.23 ° C. In order for the dehydrated aguaymanto to have a lighter color the temperature must be 60 ° C and a relative humidity of 40% and if it is desired to obtain a dehydrated aguaymanto plus yellow the temperature must be 66.78 ° C. As for the economic evaluation, a NPV of 150 532.70 soles was obtained, with a TIR of 185% and for each investment sol returns 4.74 soles of profitability. And finally a CPPC of 18.69% was obtained, concluding that the project is viable. For the application of this research has to have the proper availability of laboratory and equipment, take data closer to reality for optimal results. KEYWORDS: nutritional load, product color, drying curves, response surface, CIELAB.
