The photograph shows jujube fruits. (Source: © Aneeta Benwan-edam/Alamy Stock Photo) Jujube fruits are edible and are native to China. Jujube fruits do not store well. An investigation compared the effect of covering the fruit with an edible coating. One coating was made from chitosan, a polysaccharide obtained from the outer skeleton of shellfish. Another coating was made from cinnamon oil. Samples from stored fruit were tested for vitamin C content and antimicrobial activity. The table shows some of the results of this investigation. Plot a suitable graph to show the relationship between storage time and the vitamin C content in the fruits coated with cinnamon oil. Draw a line of best fit through the data. (4)
