As well as any other oil of sunflower is received either pressing, or extraction. Both demands additional cleaning. Certainly, clean oil on production, but if you prefer to reap it independently, then and it is necessary to clean.
Instruction
1. Filter oil by means of the special filter (represents a funnel from a nonwoven dense cloth or paper) or fabric. In such a way you will remove residues of cake, sunflower seeds and other impurity. Don't use neither during a butter manufacture, nor during its filtration metal tanks; give preference to inert materials, such as stainless steel, soft steel and aluminum with epoxy facing, glass, food plastic.
2. You filter oil immediately because impurity promote fast damage of a product. Pay attention that many hostesses instead of filtering use oil upholding reception. Close the container with oil a dense cover and leave a maximum for day. During this time oil, perhaps, will be stratified, light particles will rise to the surface, and the muddy deposit at the bottom will appear. Remove all peel and accurately merge a product in net capacity. You received unrefined oil.
3. You store such oil only in the dark. Don't place in the fridge and never fry on it as at high temperature toxic connections are formed.
4. However to filter oil insufficiently; it is important to understand that when receiving oil from seeds with pressing the structural lipids defining characteristic color, a smell and taste and also water, paraffin, wax, polycyclic aromatic hydrocarbons, residues of herbicides and pesticides pass into it, except the main group of trialglitserin. It is important to purify oil from these components as much as possible.
5. For deep cleaning use methods of odor removal and refinement of oils. Both of these processes are difficult for house reproduction and demand considerable knowledge of chemistry of substances. Refine oil by means of alkalis. Deodorize, processing dry steam at a temperature of 170-230 degrees in the conditions of a vacuum. For this purpose use special installation in which tub fill in oil, and in the tank - the required amount of water. Deodorized oil is completely ready in 3-5 hours.
