yellow passion fruit juice; high hydrostatic pressure; quantitative descriptive analysis
The aim of this study was to investigate the effects of high hydrostatic pressure on the sensory properties of passion fruit juice by quantitative descriptive analysis (QDA). The growing demand in Brazil for processed fruit pulp arouses juice industry interest to search for novel technologies with competitive advantages. High hydrostatic pressure (HHP) is an innovative technology which minimizes loss of sensory and nutritional quality, as compared to pasteurization, matching consumer demands for fresh-like foods. QDA and principal components analysis (PCA) results revealed high similarity among juice sensory attributes from in natura and pressurized samples both differing from commercial ones. Results suggest that HHP may be successfully used to preserve yellow passion fruit pulp, yielding a ready to drink juice with improved sensory quality, as compared to commercial juices available in the Brazilian market and evaluated in this study.
