The aim of this study was to evaluate the effect of different amounts of carrier agents (maltodextrin, inulin and pea protein) on the content of phenolics and carotenoids from butternut squash waste extract in encapsulates obtained by freeze-drying technique. Using Simplex-Centroid experimental design and response surface methodology (RSM), the highest content of both phenolics and carotenoids in the encapsulate was determined for a wall blend ratio 53.9 % pea protein, 46.1 % maltodextrin and 0% inulin
