食用色素染色月季切花的瓶插衰老分析及安全性评价杜婷婷,王雪,裴芳丽,张晶晶,邵玉涛,裴海霞*(内蒙古科技大学生命科学与技术学院,内蒙古包头014010)摘要[目的]探究食用色素对月季的安全性及对其切花衰老的影响。[方法]在前期使用食用色素获得染色月季的基础上,对染色月季的瓶插衰老和安全性相关指标进行观察和检测。[结果]在温度(20±2)℃、湿度(50±5)%的条件下,染色月季与未染色月季切花的瓶插寿命均为9~10d,无显著差异。食用色素染色月季切花的抗氧化酶SOD和CAT活性虽然低于未染色月季切花,但相差较小,其显著高于专业染色剂处理的月季切花的抗氧化酶活性。食用色素染色月季切花瓶插液中菌落数目显著低于专业染色剂月季切花瓶插液,且染色花瓣中铅、汞、砷的含量与未染色处理无显著差异,远低于国标要求。[结论]食用色素对月季切花的瓶插寿命和衰老影响较小,且食用色素染色月季切花的重金属含量符合国标要求,安全性有保证。关键词月季切花;染色;衰老;安全性中图分类号S685.12文献标识码A文章编号0517-6611(2023)01-0111-04doi:10.3969/j.issn.0517-6611.2023.01.024开放科学(资源服务)标识码(OSID):AnalysisofAgingandSafetyEvaluationofFoodColoringDyedRoseCuttingsinVaseDUTing-ting,WANGXue,PEIFang-lietal(CollegeofLifeScienceandTechnology,InnerMongoliaUniversityofScienceandTech-nology,Baotou,InnerMongolia014010)Abstract[Objective]Toexplorethesafetyofediblepigmentsonrosesandtheireffectsonsenescenceofcutroses.[Method]Onthebasisofusingfoodpigmentstoobtaindyedrosesintheearlystage,theindexesrelatedtobottleagingandsafetyofdyedroseswereobservedandde-tected.[Result]Theresultsshowedthatundertheconditionsoftemperature(20±2)℃andhumidity(50±5)%,thebottlelifeofbothdyedandun-dyedrosecuttingswasabout9-10dayswithoutsignificantdifferences.TheantioxidantenzymesSODandCATactivitiesoffoodcolordyedrosewerelowerthanthoseofunstainedrose,butthedifferencewassmall;theyweresignificantlyhigherthanthoseofprofessionaldyetreatedrose.Thenumberofbacterialcoloniesinthebottleinsertoffoodcoloringdyedrosewassignificantlylowerthanthatinthebottleinsertofprofessionaldyedrose,andthecontentofPb,HgandAsinthedyedpetalswasnotsignificantl...
