Juice-Profiling (NMR)

Juice Profiling™ is an NMR-based screening method for fruit and vegetable juices which has been developed in a joint effort by Bruker BioSpin GmbH and SGF International e.V.

The method for Juice Profiling was recently recognized as an official method by the International Fruit and Vegetable Juice Association (IFU).  IFU Official Method No. 87 (released 2026) is a chemical analysis procedure utilizing 1H Nuclear Magnetic Resonance (NMR) spectroscopy for comprehensive authenticity parameters in fruit juices, purées, and concentrates. It enables rapid, simultaneous quantification of key compounds like sugars and organic acids without prior separation from a single data set acquired within a few minutes.

Traditional Juice Authenticity and Quality Control Analysis is time-consuming and involves various analytical instruments and methods. However, the NMR Juice-Profiling method streamlines this process.

The significantly updated NMR Juice-Profiling 4.0 method helps to save considerable time and cost by replacing many conventional methods within one single analysis.

It allows robust and simultaneous quantitative analysis of the parameters pertaining to authenticity, including evaluation according to the limits established by AIJN (European Fruit Juice Association). HMF, arbutin, fumaric acid, phlorin, sucrose, glucose, fructose, galacturonic acid, citric acid, malic acid, alanine, lactic acid and ethanol.

Additionally, it provides valuable authenticity insights and confirmation thanks to the statistical evaluation of the NMR profiles and the comprehensive database of nearly 50000 reference samples.

Juice Profiling 4.0 boasts a routine, straightforward workflow, automatically analyzing over 60 samples in one run, with minimal sample preparation and without the use of toxic solvents.

Versatile and cost-effective, this method with its high specificity, high resolution, and fast, automated workflows for routine laboratory use, discerns the authenticity of both fruit and vegetable juices, in a comprehensive and unique way.
