充氮技术对天然矿泉水品质的影响

为了探究在矿泉水瓶轻量化包装过程中,充氮是否会影响矿泉水的品质,将3种天然矿泉水置于密闭的高压反应釜中,由氮气钢瓶向高压反应釜中充入氮气,控制氮气压强和承压时间,得到在不同氮气压强和承压时间下的待测水样。检测添加氮气前后水样感官指标、pH值、偏硅酸、碳酸盐和碳酸氢盐、溶解性总固体、钾、钠、钙、镁、锶、水分子团簇的变化情况。结果表明:氮气添加到天然矿泉水中对矿物质成分、分子团簇结构等没有影响,可为天然矿泉水轻量化包装提供参考数据。

Effect of nitrogen filling on quality of mineral water

In order to explore the effect of nitrogen filling on quality of mineral water, three kinds of mineral original water were put in airtight high pressure reaction reactor, with nitrogen filled by nitrogen cylinder. The samples under the different nitrogen pressure and pressure time were gotten by controlling the nitrogen pressure and pressure time. A series of factors were detected in the conditions, including chromaticity color, smell and taste, visible, pH, metasilicic acid, carbonates and bicarbonates, total dissolved Solids, Potassium, Sodium, Calcium, Magnesium, Strontium, water clusters. The results showed that there was no effect in mineral substance and water clusters, which provided reference data to light-weight package of natural mineral water.
