Beetroot Experiment :: Beetroots Anthocyanin Pigment Essays

Beetroot ExperimentWe are arduous to maintain how the temperature affects the rate at which the anthocyanin pigment leaves the kiosks, and at what point does the wish argue melt.Beetroot Experiment===================Task----We are trying to find how the temperature affects the rate at whichthe anthocyanin pigment leaves the cells, and at what point does thecall wall melt.Please note the ii results highlighted found in runnel 4 extradite notbeen included into my results, as they are obviously anomalous.I did the test more that once to the margin of error smaller. For thefirst a few(prenominal) times I performed the test I could have made a mistake, soto give my results a better chance of being consummate I did theexperiment four times and took the average of the tests.A represent of to clearly show the variation my results can be foundoverleaf.As the temperature increases the transmission reading on the colorimeter decreases. From information that I had already gathered I knew it would be around the 60C smirch to 65C, hence which I decided to add a test at 63C. This would help memake a more close estimate at what exact temperature the cell wallmelts. My graph shows a decrease of transparency in the water betweenthe points of 60C and 70C. From this I can make the prediction thatbetween these two points the wall melts.AnalysisThe transparency of the water fastly decreases between the points of60C and 70C because this is when the cell wall melts. The cause ofthe sharp loss of transparency is caused when the wall melts and itallows a fulminant release of the Anthocyanin pigment. So when the wallmelts the pigment is released and the transparency drops - so to findthe temperature at which the cell wall melts we just have to look forwhen there is a sudden loss of transparency in the water.My experiment shows there is a sudden loss of transparency of thewater between 6OC and 70C so I know that the cell wall must havemelted between these two points.Befor e 60C and afterward 70C the depreciation is not as drastic as between the two points. This is because before 60C there is no, or a very little amount of the pigmentallowed to exit the cell, which is not enough to alter the transparency in a big air - this is because up to this point the cell wall is still intact, and after 70C because most of the pigment has already left the cell because the cell wall has melted.
