摘要: 黄原胶(Xanthangum)是一种生物高分子化合物。它具有许多优异的性能,如:增粘性、悬浮性、耐酸碱等,并有很高的经济价值。对黄原胶的耐热性国外已有报导,KangK.S.等提到黄原胶加热至121℃、15分钟不失重。但黄原胶热稳定性如何、能耐多高的温度等尚未见报导。

Abstract: The thermal stability of xanthan gum have been studied by DTA, TG and Fourier IR. The results show that xanthan gum of China is decomposed at about 255℃, but that of U.S. is decomposed at about 250℃.
