Chocolate from Peru is gaining more importance worldwide due to the incomparable biodiversity of cocoa and its quality. This research contributes to the improvement of grinding and refining operations in the production of milk chocolate. For which the Taguchi Method was applied to determine the factors (temperature, scraping position and process time) that had a significant effect on the reduction of particle size, with the orthogonal arrangements L12 and L8 that required 36 and 24 treatments for the grinding and refining respectively. The proximal analysis of white cocoa from Piura showed 47.47 percent fat and seven percent moisture. It was roasted at 100°C for 40 minutes and then shelled, with a yield of 70 percent shelled cracked cocoa. The pieces of cocoa were subjected to grinding, to later add white sugar, whole milk powder and cocoa butter in the refinement. It was tested with grinding temperatures at three levels: 40-45℃, 37-42℃ and 37-42°C and refining at two levels: 45-50℃ and 43-48°C; with scraping positions at three levels: 3.0-3.5; 4.0-4.5 and 4.5-5.0 in grinding and at two levels: 4.5-5.0 and 4.0-4.5 in refining; and at three-time levels: 10-20, 40-50 and 10-20 min for grinding and two-time levels: 4.0-5.0 and 6.0-7.0 hours for refining; these values were assigned by the process experience of the Tinkiy company. According to the analysis of variance, the levels of the tested factors had no significant effects (p < 0.05) on the reduction of particle size, which reached the average value of 26.4 and 24.0 μm in grinding and refining, respectively; so, the subsequent optimization stage applying the response surface method was not executed.
