The point at which butter begins to melt lies between 21 °C and 40 °C. The larger amount of short-chain fatty acids in butter indicates sharpness in the melting curve. From the table below, the solid content percentage varies with the temperature at which it melts, an indication that butter doesn't have a definite melting point.
