grapefruit waste; naringin extraction, blanching, alum


In order to create semi-finished pomelo peel with crispy structure, chewy texture, eliminate bitterness, and harmonize color, it is necessary to survey to eliminate naringin under the Effect of alum and blanching time. The research process obtained experiments as follows: Shell grapefruit waste, after processing and shaping, is blanched in analum concentration with a concentration of 2% for 15 minutes will reduce naringin grapefruit peel waste.
