Xanthan gum is commonly used as a thickener in food industry, while the usage of xanthan gum as a dietary fiber is restricted for its low additive volume. Herein, the potential use of a low-viscosity and high-transparency xanthan gum as a dietary fiber was evaluated in vitro. This new xanthan shows better transparency and faster dissolution rate than most commercial products, and its viscosity increases along with the treatment of freeze-thaw cycles at -20°C. Moreover, this new xanthan can absorb heavy metals (Pb, Cd, Cu) and retard starch digestion by glucoamylase. In summary, this new xanthan could be potentially used as a dietary fiber or fiber ingredient for preventing and treating diabetes, hyperlipemia, heavy metal poisoning, and cardiovascular diseases effectively.
黄原胶在食品工业中常用作增稠剂，而由于其添加量低，作为膳食纤维的用途受到限制。在此，对一种低粘度、高透明度的黄原胶作为膳食纤维的潜在用途进行了体外评估。这种新型黄原胶比大多数商业产品具有更好的透明度和更快的溶解速度，并且其粘度随着在-20°C下的冻融循环处理而增加。此外，这种新型黄原胶可以吸收重金属（铅、镉、铜）并延缓淀粉被糖化酶消化。总之，这种新型黄原胶有可能作为膳食纤维或纤维成分有效预防和治疗糖尿病、高脂血症、重金属中毒和心血管疾病。
