Answer to Discussion question 1: Compare the amount of vitamin C per gram of vegetable with the amount per ml of fresh squeezed fruit juice. Estimate how much of the vegetable (used in your experiment) you would have to eat to equal the vitamin C content of 250 ml of fruit juice.
- Note: kale was used as the vegetable and lemon juice as the fruit juice. I'm not sure where to get the amount of vitamin C/gram of each though I was told to look it up. Thanks so much!

1. Abstract: Hamburg and leafy parsley were stored at ‐20 and ‐30°C for 9 months with or without blanching prior to freezing. We determined the vitamin C content by titration with 2,6‐dichlorophenolindophenol dye at several time intervals and storage conditions. The vitamin C content decreased over time and more when the freezing temperature was higher a. The purpose of the study is clearly stated. b. The experimental conditions are described. c. Scientific principles are described. d. The general conclusion of...
