摘要:

本实验对魔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%SiO2 流动性好,抗结效果佳。

Abstract:

Particle size and hygroscopicity of KAC, MCC and SiO2 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 30 μm, 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 flavor power added with 1% MCC or 1% SiO2 at relative humidity 90%±3% and 25± 1℃, relative humidity 75% ± 3% and 25 ± 1℃, and relative humidity 30% ± 3% and 25 ± 1℃, respectively.

Key words: KAC, anticaking agent, particle size, moisture-absorption weight gain
