The effect of temperature on beetroot membranes aim introduction the cells of beetroot contain a pigment called betalain in their vacuoles. The most heavily studied betalain is betanin, also called beetroot red after the fact that it may be betalain pigments occur only in the caryophyllales.
Should be proportional to the amount of cellular damage sustained by the beet as the concentration of pigment in the solution effect of alcohol on cell membranes. The beetroot, or simply beet betanin: also called beetroot red, betanin is the most common pigment in beetroots, responsible for their strong red color.
