CAS | 54724-00-4 |
EINECS | 232-712-4 |
化学式 | N/A |
溶解度 | 水基 (微溶),DMSO (微溶) |
存储条件 | 2-8°C |
外观 | 固体 |
颜色 | White to Pale Beige |
物化性质 | 白色至近白色粉末,几乎无臭。l%水悬浮液加热至54~78℃,再冷至40℃以下,可形成凝胶,此凝胶再加热至54~78℃,仍可溶,此为热可逆性凝胶。如加热至80℃以上,形成有弹性凝胶,此凝胶冷却后再加热(至130℃)亦不溶,是为热不可逆性。2%水悬浮液加热至90℃,凝胶强度达75g/cm。,如4%悬浮液加热至100℃并维持10min,凝胶强度可达2000g/cm2因此,该胶加热温度越高,时间越长,凝胶强度也越强。另如有硼酸存在,强度更高。在pH值在2. 0~10.0范围内,均可形成凝胶,且强度不变。因属中性多糖类,对光、热、空气均稳定。不溶于水及有机溶剂,溶于pH值12以上的碱液、甲酸。但如碱溶液加钙离子,可使之胶凝。不被人消化,不产生热量,含膳食纤维98%。 |
