Changes in Volatile Components of Passion Fruit Juice as Affected by Centrifugation and Pasteurization

Abstract

ABSTRACT Volatile components of fresh passion fruit (hybrid variety, cultivar Tai‐Non No. 1) juice (A), de‐starched juice (B), pasteurized and destarched juice (C) and headspace volatiles that were recovered during centrifugation of fresh juice (D) were compared. Charcoal adsorption was used to recover the headspace compounds. The yields of volatiles obtained from the different treatments were 31.69 mg/kg juice for A, 18.97 mg for B, 12.27 mg for C, and 7.93 mg for D, respectively. The pasteurization process (1 min at 85°C) caused a 35% loss in volatile components.
