Test Description

The quality control material is to test for Brix, pH, citric acid, total sugars and individual sugars of fructose, glucose and sucrose within orange juice. The nutritional elements important for orange juice are calcium, magnesium, potassium and phosphorus.

Fruit juices (prepared) are subject to labelling regulations for nutritional parameters and analytical testing ensures compliance with the information presented on the labels. We provide sugar content both by Brix determination and by HPLC, as total sugars (and individual sugars, if relevant). Other proximates might include ash, total acidity and pH. The PTs also include nutritionally important elements and we vary the type of juice throughout the year.

Fruit Juices, especially orange juice, enjoy vast consumption around the world, leading to increased pressure on producers and, in turn, supply chains. This can lead to manufacturers making increased use of additives to emulate and substitute for natural oranges. Accurate testing should be employed to verify any claims made by labels, such as no food additives or similar.

To ensure the effective testing required to highlight unscrupulous manufacturers or misleading labelling claims well-designed quality assurance programmes should be employed. Fapas quality control materials can be used to track your testing ability across a long timeframe, as well as standardise your testing processes through staff training activities.
