黄原胶的干热改性及复配增稠应用

该文对黄原胶进行干热改性,提高了黄原胶的速溶性和黏度,并进行红外光谱、粒度、分子质量和X-射线衍射等结构表征,最后将改性黄原胶与预糊化淀粉和麦芽糊精复配,应用于吞咽造影.结果 表明,改性黄原胶分子间发生了交联,结晶区减少,改性黄原胶的速溶性和黏度明显提高,复配增稠剂的速溶性大幅提高,吞咽造影结果证明减少了吞咽障碍引起的...

Modification of xanthan gum by dry heat and application of its compound thickening

In order to reduce the aspiration and coughing that often occurs in the elder,this article modified xanthan gum by dry heat to improve the instant dissolution and viscosity of xanthan gum,and carried out structural characterization such as infrared spectroscopy,particle size,molecular weight and X-ray diffraction.Then the modified xanthan gum was compounded with pre-gelatinized starch and maltodextrin to study the swallowing situation.The results showed that the instant dissolution and viscosity of modified xanthan gum were significantly improved,while the molecular weight was slightly increased.The modified xanthan gum has cross-linked between the molecules and the crystalline area was reduced.And the instant dissolution of the compound thickener was greatly improved.The results of swallowing radiography proved to effectively reduce the aspiration caused by swallowing disorders.
