Physico-chemical properties for identifying the honey quality in Kazakhstan and EU laws Discussion As can be seen from the table one there are differences in the analyzing methods of honey between Kazakhstan and European countries. It is very important to adopt European practice of honey quality analysis, especially using of express methods. For example, for identifying the moisture content in Kazakhstan used refractometer which shows the index of refraction, with what we can calculate the moisture content of honey (Interstate council of standardization, metrology and certification, 2012). In the European countries the moisture content measured using a Pocket Refractometer, which is considered as express method (Salonen, 2011). The situation with identifying of honey colour is very different in comparison of Kazakhstan and Europe. In European countries colour measurements are doing according to the method recommended by the International Commission of Illumination (C.I.E., 1986) with spectrophotometer in a certain wavelengths. In Kazakhstan there is no information about identifying of honey colour, but there is Russian state standard where indicated methods for this. The way of colour measurements by this standard very simple, by the visual assessment (Interstate council of standardization, metrology and certification, 2012). жүктеу/скачать 8,11 Mb.
