A coffee pulp treatment process comprising: a. Providing coffee pulp, obtainable from a production process for producing green coffee beans from coffee cherries; b. Extracting from the coffee pulp a pectin comprising extract to provide the pectin comprising extract, wherein: (i) the coffee pulp is subjected to a first extraction under acid conditions, leading to a first extraction product and a residual product, wherein the residual product is further subjected to a second extraction under alkaline conditions, leading to a second extraction product and a second residual product, and wherein the from this second extraction obtained second extraction product is recombined with the remaining first extraction product from the first extraction, and wherein these combined pectin extraction products are then further subjected to the enzymatic treatment in stage c, or (ii) the coffee pulp is subjected to a first extraction under alkaline conditions, leading to a first extraction product and a residual product, wherein the residual product is further subjected to a second extraction under acid conditions, leading to a second extraction product and a second residual product, and wherein the from this second extraction obtained second extraction product is recombined with the first extraction product from the first extraction, and wherein these combined pectin extraction products are then further subjected to the enzymatic treatment in stage c; c. Enzymatic treatment of the pectin comprising extract, wherein the enzymatic treatment comprises a treatment with one or more enzymes selected from the group consisting of an esterase and a reductase, to provide an enzymatically treated pectin material, wherein the reductase is an oxidoreductase, wherein the enzymatic treatment comprises at least a treatment with the oxidoreductase; and d. Extraction of polyphenol functionalized coffee pectin extract from the enzymatically treated pectin material. a.
