鱿鱼丝中乳糖含量的测定

Determination of Lactose in Dried Squid Shred

以苯酚、氢氧化钠、苦味酸和亚硫酸氢钠混合溶液为显色剂 ,分光光度法测定鱿鱼丝中乳糖含量。乳糖在 4— 80 μg/m L范围内与吸光度呈良好的线性关系 ,检出限为 1 .0 μg/m L,回收率为 99.8%— 1 0 0 .0 %。该法简便快捷 。

Lactose was determined in dried squid shred by spectrophotometry at the wavelength of 510nm mixed solution of phenol, sodium hydroxide,picric acid and sodium hydrogen sulphite as color developing agent.The linear range and The recovery are in the range of 4—80μg/mL and 99.8%—100.0%,respectively.The detection limit is 1.0μg/mL.The method is simple and rapid with satisfactory results.
