农产品加工2023年第1期摘要:以黑糯玉米芯为原材料,采用乙醇浸提法提取其中的花青素,电解还原法制备木糖醇。经酒精发酵和醋酸发酵,制备成富含花青素且口感较佳的保健醋酸饮品,并通过单因素试验和正交试验对发酵参数进行优化。结果表明,酒精发酵最优条件为温度30℃,pH值4.5,接种量10%,发酵时间5d,得到酒精度7.01%Vol;醋酸发酵最佳条件为酒精度7.01%Vol,发酵温度32℃,接种量10%,发酵时间5d。在此优化条件下,平均酸度约为6.27g/100mL,此时,黑玉米芯醋酸发酵饮品风味独特,具备保健功效。关键词:黑玉米芯;花青素;木糖浆;发酵;保健中图分类号:TS213.4文献标志码:Adoi:10.16693/j.cnki.1671-9646(X).2023.01.009StudyontheTechnologyofAceticAcidFermentedBeveragefromBlackCorncobYANGXiaofeng1,LIJiandong2,ZHANGLibin2,*ZHAOZhigang1(1.DepartmentofBiology,XinzhouTeachersUniversity,Xinzhou,Shanxi034000,China;2.AffiliatedMiddleSchool,XinzhouTeachersUniversity,Xinzhou,Shanxi034000,China)Abstract:Usingblackwaxycorncobasrawmaterial,anthocyaninwasextractedbyethanolextraction,andxylitolwaspre-paredbyelectrolyticreduction.Afteralcoholicfermentationandaceticacidfermentation,ahealth-careaceticaciddrinkrichinanthocyaninandbettertastewasprepared,andthefermentationparameterswereoptimizedbysinglefactorexperimentandorthogonalexperiment.Theresultsshowedthatthebestconditionsforalcoholicfermentationweretemperature30℃,pHvalue4.5,inoculumsize10%,fermentationtime5d,andthealcoholcontentwas7.01%Vol;thebestconditionsforaceticfer-mentationwerethealcoholcontent7.01%Volandthefermentationtemperature32℃,theinoculumamountwas10%,andthefermentationtimewas5d.Underthisoptimizedcondition,theaverageaciditywasabout6.27g/100mL.Atthistime,theblackcorncobaceticacidfermentedbeveragehadauniqueflavorandhadhealthcareeffects.Keywords:blackcorncob;anthocyanin;woodsyrup;fermentation;healthcare黑玉米芯醋酸发酵饮品工艺探究杨小峰1,李建东2,张利斌2,*赵志刚1(1.忻州师范学院生物系,山西忻州034000;2.忻州师范学院附属中学,山西忻州034000)收稿日期:2022-04-21基金项目:忻州市科技计划(专项)项目(20210202-7)。作者简介...
