The thesis describes the pressing of oils from fruit species, presents their selected quality parameters and evaluates the possibilities of their application in the production of cosmetics. The oil was pressed from almond, hazelnut, royal, apricot, peach, currant and rosehip seeds. Particular oils were obtained by cold pressing to produce the secondary products used. Selected substances such as fatty acid content. It also included the identification of qualitative parameters such as peroxide number, acidity number, oil acidity, oil saponification and iodine content in oils. Results show high MUFA content. Oil with its highest content is walnut (85.97%). The predominant acid in oils is oleic acid. Plum oil has the best antioxidant stability. The highest acid number is apricot oil (3.55 mg KOH.g-1). Peach oil (351,60 mg KOH / g oil) has the highest saponification number. The highest iodine number has almond oil (54,50 g.l2.100 g-1). Oils and secondary products have been used in the manufacture of cosmetic products. The choice of cosmetic products was based on market research. They were inspired by current cosmetic trends.Formula clause:The reason for postponing the publication of final thesis entitled Verification of using the secondary products after oil pressing in the cosmetic industry is the use of results of work for application output, cooperation with the commercial sector and further possible commercialization. Estimated delay is three years.
