cargeenan on the gut microbiota

Carrageenan (CGN), a sulfated high molecular weight polysaccharide is widely used in many fields, including the food industry and has a huge commercial market. The difference molecular weight (Mw) CGN played different functional properties and toxicological profiles, but the factors behind the pattern are unclear. Thus, the safety of CGN has has always been controversial for more than half a century in the international scientific community and officials.

卡拉胶（Carrageenan，CGN）作为一种硫酸化高分子量多糖，被广泛应用于包括食品工业在内的诸多领域，拥有庞大的商业市场规模。不同分子量（Molecular Weight，Mw）的卡拉胶呈现出各异的功能特性与毒理学特征，但该差异背后的核心影响因素尚不明确。因此，半个多世纪以来，卡拉胶的安全性在国际科学界与官方监管层面始终存在争议。
