摘要
为使微胶囊的空间得到充分利用,以猪血浆蛋白和海藻酸钠为微胶囊壁材材料,高密度的植物乳杆菌为芯材,结合锐孔-凝固法和冷冻干燥法制备出复合微胶囊,并研究了微胶囊的包埋率、抗消化性和贮藏稳定性。结果表明:复合微胶囊不但具备包埋高密度植物乳杆菌的能力,而且稳定性高,其中包埋率在88%以上,模拟消化后植物乳杆菌存活率在85%左右,贮藏60d后活菌数仍然高达10^(7)CFU/g。因此,猪血浆蛋白和海藻酸钠复合微胶囊不仅能对植物乳杆菌进行高密度包埋,还能起到有效的保护作用。
In order to fully utilize the space of microcapsules,composite microcapsules were prepared by using porcine plasma protein and sodium alginate as the microcapsule wall materials and high-density Lactobacillus plantarum as the core material,combined with the sharp pore-coagulation method and the freeze-drying method,and the microcapsules were investigated for the encapsulation efficiency,the antidigestive property and the storage stability.The results showed that the composite microcapsules not only had the ability to encapsulate high-density Lactobacillus plantarum,but also had high stability,in which the encapsulation efficiency was above 88%,the survival rate of Lactobacillus plantarum after simulated digestion was around 85%,and the number of bacterial count was still as high as 10^(7) CFU/g after 60 days of storage.Therefore,the composite microcapsules of porcine plasma proteins and sodium alginate not only provide high-density encapsulation of Lactobacillus plantarum,but also provide effective protection.
