6 vitamin C tablets dissolved in 500mls of water.

To ensure that tin with vitamin C solution is definitely the best combination to extend the shelf life of food such as fruits, we had to conduct another experiment whereby the comparison is between glass and tin as well as vitamin C solution and lemon juice. The result we achieved was that the tin with vitamin C solution had successfully reduced the rate of oxidation as compared to the tin with lemon juice. Reason being, in the first experiment, lemon juice was already used on fruits. The material we chose to work on was tin. In experiment 2, the objective was to find out if lemon juice was a better citric acid to reduce the rate of oxidation or vitamin C solution was a better one. Materials used: -3 effervescent vitamin C tablets dissolved in 250ml of water Time and date: 5pm, 13th April 2007 (experiment stopped on 17th April 2007) Venue: Shaded area in MargauxвЂ™s kitchen (similar environmental conditions as 3/13 classroom) It was an experiment to narrow down the number of different materials, thus making our experiment more specific and accurate. Then, using the results, we then decided to conduct another experiment between glass and tin as tin is a common packaging used for canned food. Through this experiment, we deduced that glass was the best material. The objective of experiment 1 is to find out if the fruits would oxidize faster in glass, plastic or open air and if lemon juice did help reduce the rate of oxidation. approximately 360ml of lemon juice (mixed together from different lemons) 2 pieces of plastic (for putting the fruits in open air) However, results/observations are available on the next page, as with all the other experiments.Дay Two (Tin vs. No pictures are available for this experiment as there was uploading problems. control/no solution)ДЄpple & banana in plastic container, without lemon juiceДЄpple & banana in plastic container, thoroughly dipped in lemon juiceДЄpple & banana in glass jar, without lemon juiceДЄpple & banana in glass jar, thoroughly dipped in lemon juiceДЄpple & banana without lemon juice, without packagingДЄpple & banana thoroughly dipped in lemon juice, without packaging
