摘要: 采用Tween系列乳化剂(Tween20、40、60、80)粗乳化β-胡萝卜素并经100/10MPa二级高压均质制备0.5%(W/W)β-胡萝卜素含量、不同乳化剂浓度(4%~12%)的纳米乳液,经4、25、55℃贮藏28d,根据ΔBS(t)值、贮藏过程中β-胡萝卜素纳米乳液的粒径大小以及色素含量的变化比较四种Tween乳化剂及其浓度对β-胡萝卜素纳米乳液稳定性的影响。结果表明:采用10%Tween20制备的β-胡萝卜素纳米乳液的平均粒径(d=132nm)最小,稳定性较好,而且色素保留率最高(64%~78%)。

Abstract: Oil in water nanoemulsions containing β-carotene were produced by high pressure homogenization under 100/10 MPa.The effects of four different emulsifiers(Tween 20,Tween 40,Tween 60,and Tween 80) on the stability and properties of nanoemulsions were investigated.With the variance of the ΔBS(t) of the nanoemulsion,the particle size and its polydistribution index of β-carotene nanopartical,the concentration of β-carotene during storage experiment,Tween 20 with a 10 %(W/W) concentration provided a smaller particle size(d=132 nm) and narrower distribution(PdI=0.214),and it also had a higher retention amount(64%~78%) of β-carotene after different temperature storage conditions for 28 days.
