Vitamin C, also known as ascorbic acid, is a powerful antioxidant essential for human health, but its content can vary significantly between different juices. Accurately measuring how to determine the amount of vitamin C in fruit juice is possible through several laboratory techniques, with titration being a common and accessible method.

The US Food and Drug Administration requires accurate vitamin C content to be listed on food labels. Therefore, understanding the official AOAC method of vitamin C determination is crucial for producers and consumers to ensure both quality and regulatory compliance in dietary products.

According to scientific literature, numerous analytical techniques have been reported for determining ascorbic acid content across diverse food sources. Choosing which method can be used to measure the concentration of vitamin C in food products depends heavily on the desired accuracy, budget, and the complexity of the food matrix being tested. This article explores the primary techniques available, from basic titrations to advanced chromatographic methods.

The human body requires a steady intake of vitamin C for various physiological functions, with deficiency leading to health issues like scurvy. A common and reliable method for quantifying this vital nutrient is through a redox titration using the blue dye 2,6-dichlorophenolindophenol (DCPIP).
