The Technology of Production of Cold Pressed Plum Stone Oil

Uljarice koristimo uglavnom kao sirovinu za proizvodnju jestivih ulja. Razlikujemo tri kategorije ulja, a to su: rafinirano, djevičansko i hladno prešano ulje. Visoko odabrana kvaliteta sirovine i pridržavanje propisanih pravila za način prerade sirovine značajna su za visoku kvalitetu krajnjeg proizvoda. Koštica šljive nusproizvod je prehrambene industrije iz kojeg se prešanjem sjemenke može dobiti jestivo hladno prešano ulje čijom se konzumacijom smanjuje rizik obolijevanja od kroničnih bolesti. Kod proizvodnje hladno prešanog ulja koštica šljive ne koristi se primjena topline, za razliku od proizvodnje djevičanskih ulja. Prije samog prešanja koštica šljive prolazi procese pripreme sirovine, čisti se, ljušti i melje sjemenka te nakon toga odlazi na pužnu prešu. Nakon završnog prešanja količina zaostalog ulja u pogači iznosi 8-10 % ulja. Dobivenom se sirovom ulju odvajaju netopljive nečistoće te se naknadno obrađuje, pakira u tamne staklene boce i skladišti.We use oilseeds mainly as a raw material for the production of edible oils. We distinguish between three categories of oil, namely: refined, virgin and cold-pressed oil. The highly selected quality of the raw material and adherence to the prescribed rules for the method of raw material processing are important for the high quality of the final product. The pit of a plum is a by-product of the food industry, from which, by pressing, edible cold-pressed oil can be obtained, the consumption of which reduces the risk of contracting chronic diseases. In the production of cold-pressed plum stone oil, heat is not used, in contrast to the production of virgin oils. Before pressing, the plum stone goes through the raw material preparation process, it is cleaned, peeled and ground, and then it goes to the screw press. After the final pressing, the amount of residual oil in the cake amounts to 8-10 % oil. Insoluble impurities are separated from the obtained oil and it is subsequently processed, packed in dark glass bottles and stored
