魔芋葡甘聚糖接枝丙烯酸共聚物与微晶纤维素和二氧化硅的抗结块性能比较研究

Comparison of Anticaking Functions among Konjac Glucomannan-Acrylic Acid Copolymer (KAC),Microcrystalline Cellulose (MCC) and Silicon Dioxide

本实验对摩芋葡甘聚糖接枝丙烯酸共聚物(KAC)和通用的抗结剂微晶纤维素(MCC)、二氧化硅的粒径进行了测定,并测定了它们的吸湿性能。将试样品中加入鸡精粉体中,比较了不同剂量和不同条件下它们的抗结性能。结果表明:粒径在20～30μm时,有效阻止结块,粒径越小抗结块性能越好;在相对湿度RH=90%±3%、T=25±1℃;RH=75%±3%、T=25±1℃和RH=30%±3%、T=25±1℃下添加3‰的KAC的鸡精颗粒比添加1%的MCC和1%SiO_2流动性好,抗结效果佳。

Particle size and hygroscopicity of KAC,MCC and SiO_2 were measured,and anticaking functions of these three substances added into chicken flavor powder were compared at different amounts and environmental conditions.The results showed that the smaller particle size has the better anticaking function,and when the particle size is 20 to 30μm,the anticaking function is excellent.Furthermore,the flowing and anticaking property of chicken flavor powder added with 3‰KAC are obviously better than those of chicken ...
