2023年第1期摘要:以海藻酸钠作为壁材,花青素微球包封率和产率作为考查指标,研究了海藻酸钠质量分数、CaCl2质量分数、花青素添加量和微球成型时间4个因素的影响。结果表明,花青素微球制备的最佳条件为海藻酸钠质量分数2%,CaCl2质量分数3%,花青素添加量为海藻酸钠的40%,微球成型时间2h。在基础酸乳配方上考查花青素微球的添加量对酸乳的品质影响,花青素微球在酸乳的最佳添加量为0.15%时,感官评分最高,酸乳pH值随着花青素微球添加量增大而有所降低,在4℃储存时,酸乳pH值随着储存时间增加而有所下降,且花青素微球酸乳pH值低于基础酸乳。关键词:花青素;微球;酸乳中图分类号:R735.7文献标志码:Adoi:10.16693/j.cnki.1671-9646(X).2023.01.033PreparationofAnthocyaninMicrospheresanditsApplicationinYoghurtCHENPeng,*WANGHui,BAIYan(CollegeofFoodScienceandEngineering,HainanTropicOceanUniversity,Sanya,Hainan572022,China)Abstract:Sodiumalginatewasusedaswallmaterialandtheeffectsofsodiumalginateconcentration,CaCl2concentration,anthocyaninadditionamountandmicrosphereformingtimeontheencapsulationefficiencyandyieldofanthocyaninmicro-sphereswereinvestigated.Theoptimumconditionsforthepreparationofanthocyaninmicrospheresweresodiumalginatecon-centration2%,CaCl2concentration3%,anthocyaninaddition40%ofsodiumalginateandmicrosphereformingtime2h.Theanthocyaninmicrosphereswereappliedinyogurt.Whentheoptimaladditionamountofanthocyaninmicrosphereswas0.15%,thesensoryevaluationscorewasthehighest.ThepHvalueofyogurtdecreasedwiththeincreaseoftheadditionamountofan-thocyaninmicrospheres,thepHvalueofyogurtdecreasedwiththeincreaseofstoragetimeat4℃,andthepHvalueofyo-gurtwithanthocyaninmicrosphereswaslowerthanthatofyogurt.Keywords:anthocyanin;microspheres;yogurt花青素微球制备及在酸乳中的应用陈鹏,*王卉,白燕(海南热带海洋学院食品科学与工程学院,海南三亚572022)收稿日期:2022-02-16基金项目:国家自然科学基金项目(31860453);海南省自然科学基金资助项目(321RC1073)。作者简介:陈鹏(2000—),男,本科,研究方向为食品科学与工程。*通讯作者:王卉(1968—),女,博士,教授,研究方向为天然大分子和食品加工。花青素是一类水溶性天...
