摘要
目的了解2014年兰州市市售冷冻饮品中甜味剂添加情况。方法根据GB/T 2009.28—2003中高效液相色谱法对糖精钠、安赛蜜进行检测,根据GB/T 2009.97—2003中毛细管气相色谱法对甜蜜素进行检测,同时根据GB 2760—2014对结果进行判定。结果抽检的42份自制饮料中糖精钠的检出率为57.14%,安赛蜜的检出率为50.00%,甜蜜素的检出率为47.62%,总体甜味剂的合格率为78.57%。同时连锁店和街边店中甜味剂残留量差异具有统计学意义,糖精钠(χ2=0.66,P<0.05),安赛蜜(χ2=1.56,P<0.05),甜蜜素(χ2=2.58,P<0.05)。结论市售冷冻饮品中甜蜜素有过量添加的情况,不同冷饮零售点冷冻饮品甜味剂残留量差异有统计学意义,有关部门应加强对街边冷饮零售点的质量监管。
Objective To investigate the sweetener additive level of market- sale frozen drinks in Lanzhou in 2014.Methods Sodium saccharin and Acesulfame- K were detected with high performance liquid chromatography（ HPLC） by GB / T2009. 28—2003,sodium cyclamate was detected with capillary gas chromatography（ GC） by GB / T 2009. 97—2003. The results were assayed according to GB 2760—2014. Results For the 42 self- control beverage samples,the detection rate of sodium saccharin was 57. 14%,that of Acesulfame- K was 50. 00%,and that of sodium cyclamate was 47. 62%. The overall sweetener qualified rate was 78. 57%. Meanwhile,the sweetener residue differences between in chain stores and streets stores had statistics significance,with sodium saccharin（ χ2= 0. 66,P〈0. 05）,Acesulfame- K（ χ2= 1. 56,P〈0. 05）,and sodium cyclamate（ χ2= 2. 58,P〈0. 05）. Conclusion The maket- sale frozen drinks has excessive add situation of sweentener. The differences of sweet pesticide residues in the different frozen drinks have statistical significance.
