Sažetak
Oil degumming is a treatment of eliminating undesirable non- glyceride components from crude oil such as phospholipids, lipoproteins, proteins and other compounds that cause high refination loses, decrease stability and affect sensory properties of the oil. The aim of this paper is to explore the influence of type of degumming (water, acid-water, electrolyte) on rheological properties of crude sunflower oil obtained by pressing method and calculation of the yield and loss of oil during various types of degumming processes. The effect of removal of the appearing sediment of phospholipids from degummed oil (centrifuging, pouring funnel) on rheological properties of oil was researched.
Efficiency of oil degumming was monitored by determining rheological properties of degummed oil and qualitative phosphor content in oil. Measurements of rheological properties of degummed oil were performed using rotational viscometer at 23 oC. Rheological parameters were determined by the Newton law. The results of the research have shown that all the investigated systems had Newtonian characteristics. Degumming process influences the rheological properties of oil and the amount of phospholipids retained in the oil. Degumming of crude sunflower oil with electrolyte solutions (NaCl) results in better efficiency in removal of phospholipids (lower viscosity and phosphorus content in oil). Water degumming in crude sunflower oil retained higher amount of phospholipids, because non- hydratable phospholipids are not separated from the oil. Better results are achieved by removing phospholipid sediment from the degummed oil by the centrifugation procedure than by using a pouring funnel during a 24 hour period.
