We rejected our hypothesis because Minute Maid required the most drops of iodine solution to turn orange juice/ starch indicator solution brown. The number of drops needed to change from orange to brown in Minutes Maid, Tropicana, Mr. Juicy, Sunkist, Vita, Florida’s Natural and Select are 237, 201, 197, 185, 153, 129 and 46 respectively. Therefore I conclude the vitamin C content decrease in the following order:
Minutes Maid > Tropicana > Mr. Juicy > Sunkist, Vita > Florida’s Natural > Select
Minutes Maid > Tropicana > Mr. Juicy > Sunkist, Vita > Florida’s Natural > Select
