Is it hot-pressed oil or cold-pressed oil that is best?
Hot pressing and cold pressing are the two main production processes in an oil press. In general, hot pressing is most common in the south. Cold pressing can be used in certain areas of the north. Hot pressing can also be used in certain areas. Different pressing methods can have different oil quality. The term "cooked oil" is used for hot-pressed oil. Cold-pressed oil can also be called raw oil. Cold-pressed oil differs from hot-pressed oil in that it must be fried and steam-frozen before being pressed. Hot pressing has the advantage that oil can be very fragrant and more oily than oil that is cold pressed. Cold-pressed oil retains its original flavor and nutrients while hot-pressed oil has a darker color due to high-temperature processing oil. Therefore, the oil must be filtered before it can be eaten. Cold-pressed oil has a good color, it is relatively pale and doesn't get angry. However, the oil isn't fragrant and is not bitter. Cold-pressed oil won't foam
