The effect of temperature on the pigment released by beets when boiled (HL- BIOLOGY) Research Question: Is there any significant effect of the exposure time (0, 15 & 30 minutes) to a fixed temperature (100°C) on the pigment loss by the Beta vulgaris 1 ? Exploration The Beta vulgaris , better known as the beetroot, is famously a vegetable with very high nutritive values and benefits. Characterised by its bright red colour, it is filled with minerals that improve health, such as magnesium, iron and vitamin C (Channel, 2015), it also being a great source of energy. But what is not as well known, is that the beetroots’ highest nutritional traits come from the internal pigments that reside within the plant. Said pigments are the cause for the vegetables bright red tinge, both in its insides and outsides. The beetroot contains many pigments in its interior, those of which are classified within the group of the betacyanins. Betacyanins are the substituent of the anthocyanins in 13 families of the Caryophyllales (Stintzing & R. Carle, 2004), including the beet family, and they are quite similar to the original anthocyanins, but with the inclusion of the betalain pigments within its family. This addition is quite crucial to the value and input of the betalain and betacyanin pigments to the whole nutrition aspect of the beetroot. The fact is that the small detail that makes betalains so particularly nutritious is that they contain the inorganic nitrate molecule, unlike all anthocyanins, which then the body converts into NO 2 (Yoder, 2014) and it is then directly transported into the bloodstream of the organism. Increasing the concentration of nitric oxide molecules in the bloodstream has shown to have increased the athletic performance of individuals significantly, versus the performance of those who hadn’t drunk anything, or water, prior to the activity.
