Inovacije u kontroli kvaliteta voćnih sokova

Legislation act of Fruit juices and nectars (Sl. list SRJ, No. 33/1995) and the new draft (new scheme of legislation concerning fruit, juices and nectars) are analyzed and compared in the paper. The aim was to determine the differences between old and new legislative acts. Both have general parameters of quality, such as ethanol and lactic acid contents. The new legislation includes specific parameters of quality adopted from A.I.J.N. (Association of the Industry of Juices and Nectars from Fruits and Vegetables - Code of Practice COP). They are also referenced in the Codex General Standard for Fruit Juices (247-2005). The International Fruit juice Union (IFU) has been preparing, testing and published methods of analysis for many years to assist fruit juice industry. The procedures have been prepared by experts in the fruit juice field. These specific methods of analysis are implemented in the analysis of fruit juices and nectars regarding their quality and authenticity. The analytical procedures cover all important parameters, such as the sugars, organic acids, minerals and other parameters. Numerous procedures are being used; wet chemistry, HPLC and enzyme linked assays. Numerous recommendations cover general areas such as patulin, heavy metals and oligosaccharide profiling methods. The control is necessary to avoid the import and marketing of non - authentic and even fraudulent juices and nectars whose components are sometimes completely devoid of fruit ingredients. .U radu su uporedno prikazani propisi o kvalitetu voćnih sokova i nektara iz važećeg Pravilnika i iz nacrta - predloga novog pravilnika o kvalitetu voćnih sokova i nektara. Cilj poređenja je bio da se uoče inovacije i shvati njihov značaj za kontrolisanje kvaliteta voćnih sokova i nektara. Oba pravilnika imaju opšte parametre kvaliteta, koji ukazuju na higijensku ispravnost sirovina i proizvoda (sadržaj etanola, isparljivih kiselina, mlečne kiseline). U nacrt predloženog pravilnika o kvalitetu voćnih sokova su ugrađeni tzv. 'posebni parametri kvaliteta' koji su preuzeti iz Propisa koje primenjuje AIJN (Udruženje industrije sokova i nektara). Ovim parametrima se proveravaju identitet i autentičnost sokova i nektara. Ovakva kontrola je neophodna da bi se obezbedio stvarni kvalitet ovih proizvoda i da bi se sprečio uvoz sokova i nektara koji, u stvari, to nisu po svom sastavu.
