- Utilizing spent yeast for tannin adsorption in chestnut shell treatment solutionsPublication . Vieira, Elsa F.; Amaral, Tomás; Ferraz, Ricardo; Delerue-Matos, Cristina; Ferraz, RicardoThis study evaluated the use of brewer’s spent yeast (BSY) as an adsorbent for tannins from a chestnut shell extract (CS tannin extract). This extract was derived from an alkaline treatment (5% NaOH (v/v)) to recover cellulosic material from chestnut shells and needed valorization. Various BSY treatments, including lyophilization, immobilization in calcium alginate beads, and alkaline and acid treatments, were tested to identify which had the best tannin adsorption capacity. The results highlight BSY’s potential as a system to valorize tannins from this treatment solution.
