In Colombia the industrial use of cape gooseberry is poor, which is proposed to evaluate a transformation process leading to a value added product. Functional foods are products that by virtue of their physiologically active components provide health benefits beyond basic nutrition. This research focused on the evaluation during storage of cape gooseberry powder obtained by spray drying and added with vitamin C, iron (ferrous bisglycinate), folic acid, soluble fiber (polydextrose) and soy protein. The powder obtained from the optimization of the process was stored under two different packaging conditions: with vacuum (V) and without vacuum (NV), storage time (0, 1, 2, 3, 4, 5 and 6 months) and three storage temperatures of 4, 20 and 30°C. The results indicated that the best storage condition was packaging without vacuum at a temperature of 20°C, reaching values at the end of the storage period (six months) of vitamin C, B9 and iron expressed in mg/100g of cape gooseberry powder of 22.33 ± 1.82, 261.74 ± 5.45 and 8.88 ± 0.61, respectively. Additionally, the protein and dietary fiber in g/100g cape gooseberry powder were 6.89 ± 0.27 and 10.44 ± 0.29, respectively. A diminishing trend was observed in the color parameters (CIE-Lab) during storage time being more distinct the higher the storage temperature.
