An average medium-sized orange contains approximately 70-80 mg of vitamin C, but factors like storage and processing can affect the final amount in orange juice. Testing for vitamin C concentration is a common laboratory exercise and a practical way to assess a juice's quality and nutritional value. This guide will walk you through the process, focusing on the accessible and reliable iodine titration method.

According to scientific research, ascorbic acid, commonly known as vitamin C, is highly susceptible to degradation from heat, light, and oxygen, making its accurate measurement crucial. Multiple analytical techniques are available to quantify ascorbic acid, each with specific applications and levels of precision.
