Impact of different factors on the yield and properties of fractions enriched in dietary fiber isolated from peach (Prunus persica L.) residues

The industrialization of peaches gives origin to leftover remaining from fruit canning, juice or jam production. The transformation of leftover to dietary fiber (DF) concentrates represents a strategy that can be incorporated in productive processes tending to optimize raw material use. In the prese...
