Valorization of pomace from craft cider: Nutritional value, chemical composition, and phenolic and mineral profiles

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 from emerging craft cider production novelty. This work intended to determine nutritional value, chemical composition, phenolic mineral profiles waste. Levels moisture (79.3%) sugar contents (54.0%) stand out their composition. Ethanol (1.56%) identified. Also, malic acid (2.94%), as well α-tocopherols (0.4 mg/100 g) were detected. The profile showed six flavonoid compounds identified mainly quercetin derivatives. analysis revealed potassium major constituent (58.5 mg/g). In conclusion, it envisaged that could be an ideal substrate biotechnological purposes, particularly sustainable alternative, cheap source produce glycerol application various industries such food, cosmetics, pharmaceuticals.
