肉桂膠主要由大分子量多糖組成，結構上主要是由1,4-β-d-吡喃甘露糖與1-6-連結的α-d型吡喃半乳糖的直鏈結構組成。2014年歐盟食品安全局專家組對肉桂膠作為寵物飼料添加劑的安全性發(fā)布意見。之前結論認為，只有純化的半精制肉桂膠才符合寵物食品添加劑的要求。歐盟食品安全局再次評估維持了之前的結論。

    The additive cassia gum consists mainly of high-molecular weight polysaccharides composed primarily of a linear chain of 1,4-β-d-mannopyranose units with 1,6-linked α-d-galactopyranose units. In 2014, the Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） delivered an opinion on the safety and efficacy of cassia gum.
