“…Tannin, an extract of solid waste produced in chestnut industrial processes, is an effective natural anti-oxidant for the cosmetic, food, and pharmaceutical industries (Aires et al 2016). Used coffee grounds are a great source of bioactive compounds of interest to the cosmetic and pharmaceutical industries, and methylanthines and phenols are health-related compounds present in used coffee grounds.…”

Green-Sustainable Recovery of Phenolic and Antioxidant Compounds from Industrial Chestnut Shells Using Ultrasound-Assisted Extraction: Optimization and Evaluation of Biological Activities In Vitro

“…According to Morana et al, the inner shell can contain between 2.7% and 5.2% of phenolic compounds [11]. Aires et al reported that the main phenolic compounds present in aqueous extracts of chestnut shells are gallic acid, ellagic acid, vescalagin, castalagin, epigallocatechin, catechin, and epicatechin [12]. Nevertheless, the bioactive compounds obtained from natural sources depends on the extraction process employed.…”

Evaluation of some lignocellulosic byproducts of food industry for microbial xylitol production by Candida tropicalis

“…Various lignocellulosic residues have been reported to be used for xylitol production, some of which were corncob (Cheng et al 2009; Kamat et al 2013; Ramesh et al 2013) sugarcane straw (Hernández-Pérez et al 2016), cotton stalks (Akpinar et al 2011), grape marc (Salgado et al 2012), cashew apple bagasse (Albuquerque et al 2015a), wheat straw (Canilha et al 2005), wood sawdust (Rafiqul and Mimi Sakinah 2012), vine trimming wastes (Rivas et al 2007), and rice husks (Rambo et al 2013). Chestnut shells have been used in some studies for different purposes (Aires et al 2016). Total amount of cellulose and hemicellulose in chestnut shell was reported to be 48.5 % by Gómez et al (2005).…”
