This research work was developed in order to obtain starch from barley rice (Hordeum vulgare L), to determine how particle size affects particle performance, for which, the organoleptic analysis of the raw material was carried out, later the size was reduced to proceed to mix with water applying the 2k factorial design considering process variables at speed and time with 3 repetitions each, in this way separate the macromolecules, by filtration and sedimentation until the starch precipitates at the bottom of the container, then separated from the liquid and dried at room temperature, then it was homogenized until a uniform granulometry, it was weighed and its performance determined, then the organoleptic analysis was carried out, physical, chemical and microbiological, determining that the analysis parameters are within the norm for use as raw material in other manufacturing processes. The treatments were statistically analyzed using the ANOVA and TUKEY tests to determine the significant difference between them, in addition to defining that the best treatment is 4 with 38,20 % yield.
