Abstract:
Introduction:Rongalite have many names, the trade name for sodium hydroxymethylsulfinate also sodium formaldehydesulfoxylate. It causes serious side effects to human body and is forbidden to be used as food additives by law. It is still frequently used illegally in rice and flour products. Based on this study, we determination rongalite level in some friut widespread of in our country. The study was done materials used in Lingonberry, Blueberry, Hippophae, Blackcurrant fruits collected in Khuvsgul. To determine rongalite was followed by protocol to sanitation-laboratory of food of the school of social of health in MNUMS used for NC-860 Universal Food Safety Analyzer. The concentration in sample that were measure to 153.88- 213.85 mg/kg of Lingonberry, Blueberry, Hippophae, Blackcurrant fruits weight.
Materials and methods :The study was done materials used in a Lingonberry, Blueberry, Hippophae, Blackcurrant fruits collected in Khuvsgul. To determine rongalite was followed by protocol to sanitation-laboratory of food of the school of social of health in MNUMS used for NC-860 Universal Food Safety Analyzer. Weigh accurately 5.0 g of the fruit in a plastic extract bottle, add 20 ml of distilled water, extract for 10 min by centrifugated. Than filtrate into 6 time respectively test tubes through 0.45 μm membrane using remove the color. Rongalite determined in use a disposable test tube, add 1 drop of oxidizing reagent. Amount of rongalite used for NC-860 Universal Food Safety Analyzer.
Result and discussion :Based on the obtained result, the maximum concentration observed in Blueberry was 213.85 mg/kg, and the minimum concentration observed in Hippophae was 153.88 mg/kg, the concentration observed in Lingonberry was 192.8 mg/kg, the concentration observed in Blackcurrant was 155.29 mg/kg of contained weight respectively. The difference of rongalite concentrations in wheat powder and rice powder was 0.41 mg/kg in China. Identified to the result was higher than other research.
