Summary

In the last few years the juice industry, in response to a rapidly rising market demand, has significantly increased the range of NFC juices, a fact which might be associated with growing consumer awareness in terms of proper nutrition and an interest in low-processed food. Despite such dynamic growth in the overall sales of pressed juices, pear juice remains the niche product and there is a comparative lack of publications dealing comprehensively with its quality. The aim of this study was to determine the quality of pear juices with regard to the quality requirements agreed to and implemented by the industry as well as in terms of their local authenticity and identity. It is, in fact, the latter which stands for their unique character. The research material consisted of samples representing four different varieties of pear juices  – the only commercially available ones in Poland  – half of which are registered on the List of Traditional Products kept by the Ministry of Agriculture and Rural Development. Samples came from 6 production batches. All juices were analysed for their physicochemical parameters in order to determine the degree of compliance with the guidelines of the AIJN Code of Practice. The juices were also evaluated with regard to their sensory quality. The obtained results show that all of the analysed pear juice samples meet the quality requirements agreed to and implemented by the industry. There were no significant differences between the two analysed groups of pear NFC juices. They are also characterized by a similar degree of non-compliance with the guidelines of the AIJN Code of Practice as far as the criteria for the assessment of their authenticity and identity are concerned.
