| you are: Definition of quality and naturalnosti honey
Definition of the maintenance of the general sugar (sugar after inversion). Take a pipette of a working solution of honey of 20 ml and pour in it in a flask having capacity of 200 ml. Here add 80 ml of the distilled water, and then 5 ml of the concentrated hydrochloric distilled water, and then 5 ml of the concentrated hydrochloric acid.
Inversion spend the same as it is specified above (preparation of a standard solution invertnogo sugar).
Definition of the maintenance of the general sugar after inversion spend the same as also definition of sugar before inversion.
For definitive result of test take an average arithmetic results of two simultaneously spent tests. Thus the divergence between these two tests should not exceed 0,5%.
The Maintenance of sugar before inversion or sucrose in percentage on waterless substance calculate multiplication of percentage of reducing Sugars (sucrose) in honey on factor.
Definition vodnosti honey. At the raised maintenance of water in honey it quickly sours and is unsuitable for long storage.
Most precisely to define percentage of water in honey it is possible with the help refraktometra marks RDU or RL. For analysis carrying out are necessary a water bath with an electroheater, the mercury thermometer with the price of division 1 °, allowing to take temperature from 0 to 100°С, glass test tubes in height of 30-40 mm and diameter 7 mm.
For definition vodnosti use liquid medical If it zakristallizovalsja, it dissolve. In a test tube place 1 sm3 of honey and close a rubber stopper. A test tube with honey place in a water bath and heat up at temperature 60°С to full dissolution of crystals of honey.
If definition spend at temperature more low or above 20°С enter the amendment on each degree of Celsius: for temperature above 20 ° add to an indicator of refraction 0,00023, for temperature more low 20 ° subtract from an indicator of refraction 0,00023.
Supposed divergences between results of control definitions should not exceed 0,1%.
