NMR-Based Multi Parametric Quality Control of Fruit Juices: SGF Profiling
نویسندگان
چکیده
With SGF Profiling™ we introduce an NMR-based screening method for the quality control of fruit juices. This method has been developed in a joint effort by Bruker BioSpin GmbH and SGF International e.V. The system is fully automated with respect to sample transfer, measurement, data analysis and reporting and is set up on an Avance 400 MHz flow-injection NMR spectrometer. For each fruit juice a multitude of parameters related to quality and authenticity are evaluated simultaneously from a single data set acquired within a few minutes. This multimarker/multi-aspect NMR screening approach features low cost-per-sample and is highly competitive with conventional and targeted fruit juice quality control methods.

In this study, the mineral contents of bread with boiled grape, date, carob and mulberry fruit juices at five different concentrations were determined. The fluctuations of B and Cu contents in bread with pekmez (molasses) were determined between 4.10 to 4.49 mg/kg and 2.74 and 3.34 mg/kg respectively. Ca, Mg, K, P and S were the main macro-elements of bread samples. The highest values of Ca...
