Assessing of potential of Aronia Berries residue after juice extraction as a feedstock for platform molecules production

The recovery of fruit industrial waste for the production of added value compounds is a topic of great importance for the application of circular economy principle. Pomace waste coming from Aronia melanocarpa industrial utilization is an interesting source of bioactive compounds such as dietary fibre, pectins, cell wall polysaccharides, vitamins, polyphenols, phospholipides. The extraction of bioactive substances has been carried out through an enzymatic approach followed by ultrafiltration technique. The obtained residues have been collected and characterized. The obtained data revealed the presence of free and complex sugars such as glucose, fructose, sorbitol, EHS and cellulose that could be considered starting feedstock for platform molecule production.
