摘要
为探索水溶性物质微囊化新方法,利用高压电场微胶囊成型装置制备W/O/W型微囊,内水相为蒸馏水,油相为液体石蜡,外水相为海藻酸钠溶液。研究了电压、液面距、推进速度、初乳/外相水溶液、海藻酸钠浓度对微囊粒径的影响。结果表明:在成囊范围内,电压、液面距和外水相海藻酸钠溶液浓度对微囊的粒径有较为显著的影响。在电压3.15kV～4kV,液面距2.5cm～10cm,海藻酸钠浓度0.6%～1.2%,可以制得微囊粒径范围为50μm～1000μm,大小均匀的复乳微囊。
To study the new method of microencapsulating water soluble matter, water-oil-water microcapsule was prepared by high-voltage electrostatic apparatus, its inner, oil and outer phase was distilled water, liquid paraffin and NaAlg solution respectively. The effects of voltage, push speed, first emulsion/outer phase solution, NaAlg concentration on the diameter of microcapsule were evaluated. The results showed that the voltage and NaAlg concentration had noticeable effects on microcapsule diameter in the range of forming microcapsule. In the conditions of volt was 3.0-4.0 kV, electric field height was 2.5-10 cm and NaAlg concentration was 0.6-1.2%, homogeneous microcapsules which diameter was between 50-1000μm were produced.
