Coffee is one of the most consumed products in the world, and its by-products are mainly discarded as waste. In order to solve this problem and in the context of a sustainable industrial attitude, coffee by-products have been studied concerning their chemical and nutritional features for a potential application in foodstuffs or dietary supplements. Under this perspective, coffee silverskin, the main by-product of coffee roasting, stands out as a noteworthy source of nutrients and remarkable bioactive compounds, such as chlorogenic acids, caffeine, and melanoidins, among others. Such compounds have been demonstrating beneficial health properties in the context of metabolic disorders. This mini-review compiles and discusses the potential health benefits of coffee silverskin and its main bioactive components on metabolic syndrome, highlighting the main biochemical mechanisms involved, namely their effects upon intestinal sugar uptake, glucose and lipids metabolism, oxidative stress, and gut microbiota. Even though additional research on this coffee by-product is needed, silverskin can be highlighted as an interesting source of compounds that could be used in the prevention or co-treatment of metabolic syndrome. Simultaneously, the valorization of this by-product also responds to the sustainability and circular economy needs of the coffee chain.
咖啡是世界上消费最多的产品之一，其副产品主要作为废物丢弃。为了解决这个问题，并在可持续产业态度的背景下，人们对咖啡副产品的化学和营养特性进行了研究，以探讨其在食品或膳食补充剂中的潜在应用。从这个角度来看，咖啡银皮作为咖啡烘焙的主要副产品，是一种值得注意的营养物质和显著生物活性化合物的来源，如绿原酸、咖啡因和类黑素等。这些化合物在代谢紊乱的背景下已显示出有益健康的特性。这篇综述汇编并讨论了咖啡银皮及其主要生物活性成分对代谢综合征的潜在健康益处，强调了其中涉及的主要生化机制，即它们对肠道糖吸收、葡萄糖和脂质代谢、氧化应激和肠道微生物群的影响。尽管还需要对这种咖啡副产品进行更多研究，但银皮可被视为一种有趣的化合物来源，可用于预防或辅助治疗代谢综合征。同时，这种副产品的价值提升也符合咖啡产业链的可持续性和循环经济需求。
