Abstract Nuclear magnetic resonance (NMR) spectroscopy is rapidly gaining importance in mixture analysis, originally driven by the pharmaceutical and nowadays also clinical applications within metabonomics. Quality control of food‐related material has very similar requirements, as it deals with mixtures, many compounds found body fluids are analyzed well. NMR allows analysis two ways one experiment: namely, targeted untargeted. Targeted stands for safe identification consequent...
With SGF Profiling™ we introduce an NMR-based screening method for the quality control of fruit juices. This has been developed in a joint effort by Bruker BioSpin GmbH and International e.V. The system is fully automated with respect to sample transfer, measurement, data analysis reporting set up on Avance 400 MHz flow-injection NMR spectrometer. For each juice multitude parameters related authenticity are evaluated simultaneously from single acquired within few minutes....
The isotopic composition (δ15 N, δ18 O) of nitrate in fruits and vegetables differentiates organic from conventional food production practices. Organic systems do not use synthetic fertilizers high 18 O low 15 N thereby help reveal producers' fertilization claims. Isotope analyses extracted are done by bacterial reduction which is costly specialized laboratories. Rapid, low-cost methods needed to promulgate isotope products support product certification verify the authenticity claims.Fresh...
Abstract An improved procedure for determining 2 H/ 1 H isotope ratios, using gas chromatography-isotope ratio mass spectrometry, has been used to detect the addition of exogenous C4-plant-derived sugars pineapple juice. Isotopic techniques are commonly identify low-cost fruit juices and difficult subvert as it is not economically viable change isotopic ratios sugars. However, cane sugar juice presented a significant challenge that only detected by site-specific 13 C analysis methyl...
Nuclear Magnetic Resonance (NMR) has been used for structure analysis of pure compounds over decades. Opposite to this, the extraordinary potential NMR just started be recognized and exploited in mixtures context biofluids food beverages. In our contribution, we will show results studies done field beer already developed BRUKER-SGF-Profiling Method, Fruit-Juice Screener. We show, that from very same set spectra several specific parameters can derived. 1H combination with pattern recognition:...
Hydrogen stable isotope analysis of fruits can provide valuable information about their geographical origin, growing conditions, and the underlying environmental factors. The isotopic ratios in are related to water they absorb incorporate during photosynthesis. Nevertheless, measuring non-exchangeable hydrogen plant-related organic compounds such as carbohydrates polysaccharides face well-known analytical challenges (1). One strategy overcome this challenge is by an established method which...
