Abstract: 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. Industrial relevance: The findings achieved in the study have important implication to the industry, because they demonstrated the positive effect of pressurization on the sensory properties of passion fruit juice. Pressurized juice should meet consumer’s expectation and demand regarding a more natural, and free of cooked and artificial flavor attributes, yielding a product more similar to the freshly made one.

Prato cheese, a typical ripened Brazilian cheese, contains high levels of sodium, and the excess intake of this micronutrient is associated with hypertension and cardiovascular diseases. A technological alternative to reduce the sodium content in foods is to replace NaCl with KCl and the addition of flavor enhancers. The present study aimed to combine quantitative descriptive analysis (QDA) and temporal dominance of sensations (TDS) to assess the sensory profile of reduced-sodium probiotic prato cheese with the addition of flavor enhancers. Five formulations of probiotic prato cheese were manufactured using 1% (wt/wt) salt as follows: C1 (100% NaCl), C2 (50:50 NaCl:KCl), C3 (50:50 NaCl:KCl + 1% arginine), C4 (50:50 NaCl:KCl + 1% yeast extract), and C5 (50:50 NaCl:KCl + 1% oregano extract). Both methods indicated that the addition of flavor enhancers modified the sensory profile of the reduced-sodium probiotic prato cheese. The QDA revealed that flavor enhancers-in particular, yeast and oregano extract-increased the saltiness of samples C4 and C5, respectively, and that the other flavor enhancer, arginine (sample C3), most modified the attributes of prato cheese. The TDS dominance curves revealed that the addition of yeast extract (sample C4) had a positive effect on cheese flavor because it minimized the bitter taste perception resulting from the addition of potassium chloride. Overall, QDA and TDS used together provided interesting insights for establishing the sensory profile of reduced-sodium probiotic prato cheese., (Copyright © 2018 American Dairy Science Association.
