摘要: 将玉米皮膳食纤维超细粉碎后研究其粉体特性,对不同粒度玉米皮膳食纤维粉的填充性、流动性、吸湿性进行研究。结果表明:当粒度为160目时,松密度为0.3405g/mL、振实密度为0.4555g/mL、压缩度为25.25%、流速为2.97g/s、休止角为43.38°时,玉米皮膳食纤维粉适合膳食纤维片剂产品的生产。

Abstract: The properties of corn spermoderm dietary fiber power were explored after ultra-fine grinding. The fillibity, fluidity and hygroscopicity of dietary fiber power with different sizes were also studied. The results showed that the bulk density, tap density, compressibility, flow rate and repose angle were 0.3405 g/mL, 0.4555 g/mL, 25.25%, 2.97 g/s and 43.38° when the size of dietary fiber power was 0.096 mm. Therefore, corn spermoderm dietary fibers were suitable to produce dietary fiber products.

Key words: corn spermoderm, dietary fiber, power property
