Dear Colleagues,
Recent digital developments in food, beverage, and packaging analysis have been focused on using contactless sensors, such as remote sensing and biometrics, to assess the quality traits of produces, detect packaging defects during the production process, and understand perception through sensory analysis based on consumer biometrics. The implementation of these novel techniques is aiding the food, beverage, and packaging industries in the rapid, efficient, cost-effective, and reliable evaluation and assessment of products at any stage of the production chain for the early detection of potential faults within the process and consumer evaluation of the final product and packaging.
This Special Issue will bring together high-quality papers focused on these technologies and their applications in the food and beverage industries, including packaging assessments. These contactless sensors incorporate electronic noses and tongues, the use of infrared thermal cameras, UV-Vis, mid- and near-infrared spectroscopy, and computer vision analysis, among others. These technologies may be applied to assess food, beverages, and packaging quality traits such as sensory attributes, physicochemical components, nutritional values, and defects, at any stage in the production chain, which aid in the quality assessment of products.

Grapevine smoke exposure and the subsequent development of smoke taint in wine has resulted in significant financial losses for grape growers and winemakers throughout the world. Smoke taint is characterized by objectional smoky aromas such as “ashy”, “burning rubber”, and “smoked meats”, resulting in wine that is unpalatable and hence unprofitable. Unfortunately, current climate change models predict a broadening of the window in which bushfires may occur and a rise in bushfire occurrences and severity in major wine growing regions such as Australia, Mediterranean Europe, North and South America, and South Africa. As such, grapevine smoke exposure and smoke taint in wine are increasing problems for growers and winemakers worldwide. Current recommendations for growers concerned their grapevines have been exposed to smoke are to conduct pre-harvest mini-ferments for sensory assessment and send samples to a commercial laboratory to quantify levels of smoke-derived volatiles in the wine. Significant novel research is being conducted using spectroscopic techniques coupled with machine learning modeling to assess grapevine smoke contamination and taint in grapes and wine, offering growers and winemakers additional tools to monitor grapevine smoke exposure and taint rapidly and non-destructively in grapes and wine.

Abstract
Labels concepts, information, logo, figures, and colors for beverages are critical for consumer perception, preference, and purchase intention. This is especially relevant for new beverage products. During social isolation, many sensory laboratories were unable to provide services, making virtual sensory sessions relevant to study different label concepts and design preferences among consumers. This study proposed a novel virtual sensory system to analyze coffee labels using videoconference, self-reported and biometric analysis software from video-recordings to obtain sensory and emotional responses from 69 participants (Power analysis: 1 – β > 0.99) using six different label concepts: i) fun; ii) bold; iii) natural; iv) everyday; v) classic and vi) premium. Results showed that the label concept rated as highest perceived quality was the Premium presenting significant differences (p < 0.05) compared to all other concepts. The least score for perceived quality was attributed to Bold due to confronting aroma lexicon (cheese sip), which is supported by previous studies. Furthermore, even though graphics, colors, and product name could be considered positive attributes, they do not determine perceived quality or purchase intent, which was found for the concepts bold, everyday, and classic. The findings form this study were expected and are consistent with those from similar publications related with labels, which shows that the proposed virtual method for sensory sessions and biometrics is reliable. Further technology has been proposed to use this system with multiple participants, which could help beverage companies perform virtual sensory analysis of new products’ labels.

Climate change forecasts higher temperatures in urban environments worsening the urban heat island effect (UHI). Green infrastructure (GI) in cities could reduce UHI by regulating and reducing ambient temperatures. Forest cities (i.e. Melbourne, Australia) aimed for large-scale planting of trees to adapt to climate change in the next decade. Therefore, monitoring the green infrastructure of cities requires close assessment of growth and water status at the tree-by-tree resolution for its proper maintenance, and needs to be automated and efficient. This project proposed a novel monitoring system using an integrated visible and infrared thermal camera mounted on top of moving vehicles. Automated computer vision algorithms were used to analyze data gathered at an Elm trees avenue in the city of Melbourne, Australia (n = 172 trees) to obtain tree growth in the form of effective leaf area index (LAIe) and tree water stress index (TWSI), among other parameters. Results showed the tree-by-tree variation of trees monitored (5.04 km) between 2016-17. The growth and water stress parameters obtained were mapped using customized codes and corresponded with weather trends and urban management. The proposed urban tree monitoring system could be a useful tool for city planning and GI monitoring, which can graphically show the diurnal, spatial, and temporal patterns of change of LAIe and TWSI to monitor the effects of climate change on the GI of cities.
There is a rare opportunity for a dual PhD between The University of Melbourne, Australia and The University of Manchester, UK for the novel development of sensor technology and AI to obtain grapevine berry maturity levels based on berry cell death for optimal winemaking purposes.
