摘要
以木薯纳米淀粉稳定Pickering乳液,以乳析指数、贮藏稳定性、粒径分布及流变特性作为指标,考察纳米淀粉添加量、离子强度、温度、pH对乳液性质的影响。结果表明,纳米淀粉添加量7.5%时,乳液综合性质最佳,液滴大小分布较均匀,室温贮藏30 d无分层现象,粒径最小,为115.30 nm;表观黏度、储能模量、损耗模量最大,表现为凝胶特性。此条件下,乳液具有较强的盐离子抵抗力,最适贮藏温度为25~70℃、pH为2.00~6.00。
Pickering emulsion stabilized by cassava starch nanoparticles,the creaming index,storage stability,grain size distribution and rheological properties as index.The influence of starch nanoparticle,ions strength,temperature and pH on emulsion properties were investigated.The results showed that at 7.5%of starch nanoparticles,the comprehensive properties of emulsion were better than that of control samples.The droplet size distribution of emulsion was relatively uniform,and there was no layering phenomenon after 30 d of stored at room temperature.The smallest droplet size of emulsion was 115.30 nm,while the emulsion viscosity,storage and loss modulus reached the peak,and the emulsion appeared gelatinous.In this condition,emulsion exhibited strong resistance to salt ions,and the optimal storage temperature and pH were 25~70℃,2.00~6.00,respectively.
