    Several molecules of the hemp plant, such as CBD and THC, have been shown to be effective as treatments for psychiatric and other conditions such as sleep disorders, migraines, cancer pain, seizures and skin diseases. However, social stigma about the cultivation and consumption of this plant limits access to these treatments despite the fact that CBD has no psychoactive properties. The present study focused on making a microencapsulated product that combines the medicinal benefits of the hemp plant with the addition of sacha inchi oil, which is rich in fatty acids and vitamins, as an added value. To this end, an emulsion was made from a mixture of hemp, sacha inchi and sunflower oils together with gum arabic and maltodextrin, which fed a spray dryer to obtain a whitish powder, obtaining a yield of 63.87 percent in the best treatment, Subsequently, tests were carried out on the microencapsulated product where it was determined that it obtained an average humidity of less than 1.5 percent in the first week after it was obtained and 2.9 percent after 10 weeks of storage, it was also obtained that the fluidity of the microencapsulated product was not very acceptable even after the application of excipients to improve the fluidity, finally an infrared FTIR-ATR test was carried out where a good level of microencapsulation was qualitatively determined.

    A blend of Sachai inchi oil and Girasol oil was microencapsulated with a fatty acids balance 4,42 times the fatty acid linoleic content (omega-6) than the fatty acid linolenic content (omega-3) into a polymeric matrix of Maltodextrin and Arabic gum, ratio 1:1. A 81,06 mores less 1,75 percent of performance and 92,08 more less 0,71 percent of efficiency of process was obtained with an inlet air temperature of 150 Celsius degree and 33 percent of oil´s charge. The microcapsules have 1,96 more less 0.04 percent of moisture, with a smooth surface and pore-free which protects to oil´s blend inside. Without significative changes about its fatty acids content after microencapsulation process, the product has a lipid profile of 10,20 more less 0,14percent for omega-3, 46,18more less 0,50 percent for omega-6 and 23,83 more less 0,24 percent for omega-9. When scaling the process at an industrial level, a product with similar characteristics to those obtained at laboratory scale is obtained.
