Special Issue Information

Dear Colleagues,

Flavor and palatability are the two most important factors in determining consumer acceptance in foods. Non-volatile and volatile compounds interact with the human sensory system to arouse appetite and influence food choice. Palatability is related not only to aroma and taste compounds but also to viscosity, density, cohesiveness, and other aspects of the textural profile of foods. All of the above factors together establish multidimensional perception stimulation for humans. Consumer acceptance is also a consequence of complex factors, including food culture, dietary habits, emotions, health conditions, and eating environments.

In this Special Issue’s second edition, we welcome submissions that discuss flavor, palatability, and consumer acceptance in foods. We also encourage potential authors to submit articles addressing the applications of biosensors in evaluating food quality. Articles that discuss the effects of food processing, pre-/post-harvest aspects, or packaging on sensory characteristics are also welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Application of Virtual Reality to Alter Sweetness Perception

Regular consumption of excess sugar is linked to nutrition-based diseases, including gut problems, Non-Alcoholic Fatty Liver Disease, and Type 2 Diabetes Mellitus. Increasing sweetness perception is a novel technique to decrease sugar consumption. This experiment compared the sweetness perception of sweetened and unsweetened almond milk in response to different virtual environments with music and visuals. Two music types, the classical song Goldberg Variations, BMV. 998-Variation 13 and a jazz song generated by AI were used. Additionally, fall and spring forest backgrounds were generated by the Blockade Labs 3D image generator. Each participant tasted sweetened and unsweetened almond milk in music-only, background-only, and combination music and background environments. Results revealed significant differences in sweetness ratings for music type (p = 0.015) and between milk types (p < 0.001). Viscosity rating differed significantly between backgrounds (p = 0.04) and by milk type (p < 0.001). Liking ratings varied significantly between backgrounds (p < 0.001) and between music genres (p = 0.011). The results suggest that altering music and background may be a strategy to change sweetness and viscosity perception in unsweetened beverages. Full article

High pressure processing (HPP) and ultrasound-assisted extraction (UAE) can effectively shorten extraction time and increase extraction efficiency of the cold brew (CB) process. However, their application in CB citri reticulatae pericarpium (CRP) and the underlying mechanisms of flavor modulation remain poorly understood. In this study, CB-CRP beverage was prepared with HPP-assisted, UAE-assisted, and HPP+UAE-assisted extraction from 1, 3, 5, and 10 years CRP. Results revealed that the total soluble solids (TSS), total sugars, flavonoids, polyphenols, and volatile organic compounds (VOCs) and antioxidant activity of CB-CRP increased after assisted extraction. The combined application of HPP and HPP+UAE-assisted extraction exhibited the most pronounced effects. The kinds and total content of VOCs of CB beverages prepared from 10-year-aged CRP increased from 45 to 81, and from 2.44 to 5.98 μg/mL, respectively. Moreover, the combined HPP+UAE extraction promoted the enrichment of fatty and woody aroma-related compounds, which drove a shift in the flavor profile from fresh to a richer woody type. And this endowed the CB-CRP water with a more complex and multidimensional aroma profile. Full article
