The phenolic profiles of snack bars obtained by HPLC
resembled that of the APE ingredient. The Hunter L*a*b* colour and water activity values suggested that
the addition of APE did not cause extra browning and the resultant snack bars would possess a good shelf
life. Therefore, snack bars enhanced with apple DF and APE may be a convenient functional food, offering
a good source of DF and apple polyphenols.
