Resumo(s)
Waste recovery, in a circular economy context, is associated with clear economic and
environmental benefits. Although apple pomace has been extensively studied for many
applications, the valorization of pomace from emerging craft cider production is a
novelty. This work is intended to determine the nutritional value, chemical
composition, and phenolic and mineral profiles of pomace from craft cider waste.
Levels of moisture (79.3%) and sugar contents (54.0%) stand out in their composition.
Ethanol (1.56%) has been identified. Also, malic acid (2.94%), as well as α‐tocopherols
(0.4 mg/100 g) were detected. The phenolic profile showed six flavonoid compounds
identified mainly quercetin derivatives. The mineral analysis revealed potassium as the
major constituent (58.5 mg/g). In conclusion, it is envisaged that cider pomace could be
an ideal substrate for biotechnological purposes, particularly as a sustainable and
alternative, cheap source to produce glycerol for application in various industries such
as food, cosmetics, and pharmaceuticals.
