In the present paper, 26 food waste streams were selected according to their exploitation potential and investigated in terms of pectin content. The isolated pectin, subdivided into calcium bound and alkaline extractable pectin, was fully characterized in terms of uronic acid and other sugar composition, methylation and acetylation degree. It was shown that many waste streams can be a valuable source of pectin, but also that pectin structures present a huge structural diversity, resulting in a broad range of pectin structures. These can have different physicochemical and biological properties, which are useful in a wide range of applications. Even if the data could not cover all the possible batch by batch and country variabilities, to date this represents the most complete pectin characterization from food waste streams ever reported in the literature with a homogeneous methodology.
在本论文中，根据26种食物废物流的开发潜力进行了筛选，并对其果胶含量进行了研究。分离出的果胶分为钙结合型和碱提取型果胶，对其糖醛酸和其他糖类组成、甲基化和乙酰化程度进行了全面表征。结果表明，许多废物流可能是果胶的宝贵来源，而且果胶结构呈现出巨大的结构多样性，从而导致了广泛的果胶结构类型。这些果胶结构可能具有不同的物理化学和生物学特性，可用于广泛的应用。即使这些数据无法涵盖所有可能的批次和国家差异，但迄今为止，这是文献中报道的采用统一方法对食物废物流中果胶进行的最完整表征。
