AN ~1H-NMR-TECHNIQUE FOR HIGH THROUGHPUT SCREENING IN QUALITY AND AUTHENTICITY CONTROL OF FRUIT JUICE AND FRUIT JUICE RAW MATERIALS - SGF-PROFILING

摘要

The "natural" and "healthy" image of fruit juices and derived products is one of the reasons leading to their dynamic evolution in the global food sector. The fruit juice industry purchases its raw materials in a world-wide market. Despite a general trend in the food industry to install suitable traceability systems, the need for analytical control of authenticity and legal conformity has increased over the last years. Due to the relatively large natural variability and more-and-more ingenious adulterations observed on the market, sophisticated control has become an important economic factor in the fruit juice industry. Therefore the European fruit juice industry runs an own independent and global advanced quality control system for raw materials, SGF/IRMA (SGF International e.V. - Sure Global Fair - International Raw Material Assurance). SGF/IRMA co-operates with national and regional control organisations for market finished fruit juice products organised in the European, organisation EQCS (European Quality Control System). Such control systems, official control bodies and individual companies have to analyse a very large number of products. The whole range of possible quality deviations can not be tested by routine analyses for cost reasons inevery case.
