GB/T 6682 analytical laboratory use specifications and test methods (GB/T 6682-2008, ISO 3696. 1987, MOD) Principle 3 Honey sample starch granules may be combined with iodine to generate a blue complex, it can be observed under a microscope count. When the starch amylose and amylopectin ratio is not at the same time, the colors may appear to be blue, purple or red.4 Reagents and materialsUnless otherwise indicated, at least in the analysis using analytical reagent. The water is distilled or deionized water, which should be consistent with GB/T 6682 in Three water standards. 4.1 iodine - potassium iodide solution (0.3%). weigh 3g iodine, 6g potassium iodide, dissolved, and water volume to 1000mL. 4.2 hemacytometer (25 × 16). 4.3 conical graduated centrifuge tube (15mL). minimum scale 0.1mL. 4.4 straw (10mL). 4.5 dropper. 4.6 coverslip.5 Equipment5.1 centrifuge (3000r/min). 5.2 microscope (× 100, × 400). 5.3 Balances (a sense of volume 0.01g). Preparation 6 samples 6.1 Weigh homogeneous honey sample 2.0g, add water, 20mL, boiled cooled. This sample solution used for qualitative testing. 6.2 Weigh uniform honey 50.0g, 25mL diluted with water, and mix. This sample solution is used to test the microscope counting.7 Procedure7.1 Qualitative Test Take honey sample solution (6.1) a little, add 2 drops of iodine solution, the same color as the honey were no starch; if blue, green, purple-doped Starch, red if the added dextrin. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23192-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 23192-2008_English as soon as possible, and keep you informed of the progress.
