This study aimed to produce and evaluate artisanal garrafa ice cream made with goat milk, performing microbiological analysis and sensory evaluation, and comparing it with cow milk-based ice cream. Pasteurized goat and cow milk were used to prepare pecan and chocolate cookie-flavored ice creams. Microbiological tests confirmed the absence of total and fecal coliforms, as well as aerobic mesophiles, indicating adherence to Good Manufacturing and Hygiene Practices. All products complied with the microbiological safety limits established by Mexican Official Standards. Sensory evaluation techniques are essential for assessing how attributes such as appearance, aroma, color, flavor, and texture influence consumer preferences for dairy products. A sensory evaluation was conducted with 72 untrained panelists. Among all samples, pecan-flavored goat milk ice cream received the highest preference, particularly for its taste and texture. Panelists also noted differences in color and odor between goat and cow milk ice creams. The sensory analysis highlighted the distinctive organoleptic properties of goat milk ice cream and its potential for consumer acceptance. These findings suggest that artisanal goat milk ice cream, especially the pecan variety, can successfully compete with traditional cow milk products in the expanding market for innovative and high-quality dairy foods.

Tanomenon Sorva (TS), a traditional yogurt-based soup at the heart of Pontic Greek cuisine, is examined as a marker of identity among descendants of Pontic Greeks in Western Macedonia, Greece. Guided by social constructionism and practice theories, we conducted participant observation and semi-structured interviews with 11 women aged 54–86 years and analyzed data using reflexive thematic analysis (RTA). Four key themes emerged: (1) Cultural Continuity and Tradition; (2) Social Bonding Through Food; (3) Adaptation, Challenges, and Loss; and (4) Health and Nourishment. We argue that this iconic, tangy soup operates as a cultural code and habitual practice that stitches memory, belonging, and embodied well-being. Against pressures of culinary homogenization, TS remains a powerful symbol and a practical tradition that helps a group preserve its unique identity. Full article

The art of food–drink pairing has always fascinated gourmets and cooking enthusiasts. While wine has long held pride of place on the table, natural mineral water plays a central role in this new concept. Through the Pyramid of Natural Mineral Waters, we aim to explore the relationships between the structure of water and food, flavors and aromas, revealing a world of previously unexplored nuances and tastes. This new approach is based on the analysis of the fixed residue of water, i.e., the amount of mineral salts dissolved in it. The fixed residue gives the water unique organoleptic characteristics, influencing the perception of flavors and sensations in the mouth. By analyzing the technical data sheet of mineral waters designed by us, it is possible to identify their main characteristics and combine them in a consistent way with various dishes, as proposed in the pyramid scheme. There are many possible combinations between natural mineral waters and foods, depending on numerous factors, including the type of water and the salts dissolved in it, the type of food, the cooking method, and the types of sauces and condiments present in the dish. To guide consumers in this fascinating universe, the figure of the water sommelier, or so-called hydro-sommelier, was born. As expert connoisseurs of natural mineral waters, they are able to recommend the ideal water for every occasion, maximizing the taste characteristics of the food served at the table. This study is completed with the construction of the Pyramid of Natural Mineral Waters, which relates the composition of water, specifically the salient characteristics related to dissolved minerals, with the respective food combinations recommended by us, in relation to the structure of both water and food.

Many meals are consumed in public settings such as schools, hospitals, and elderly care. These meals have the potential to impact public health as well as promote sustainable lifestyles. However, gastronomic values can be important for loading the meals with other dimensions. The aim of this article is to explore how the concept of gastronomy is understood, used, and described in the scientific literature in the context of public meals. For this scoping review, a systematic approach was adopted, including articles that use the concept of gastronomy in the context of public meals, as defined in this paper. A total of 3676 articles were initially identified, of which eight were finally included for assessment in this review. Three main themes emerged in the analysis, illustrating how the concept of gastronomy was used: gastronomy as local food and national cuisine; gastronomy as ideas of ‘the good’; and gastronomy as a framework. The concept of gastronomy is seldom clearly defined but is often used to emphasize ideas of ‘the good’, local food, and culinary traditions. Through gastronomy, healthy and sustainable public meals can be loaded with additional value, creativity, and innovation, enhancing the overall meal experience. Full article

This preliminary study explores the use of a smart tray prototype equipped with a weight sensor to analyze consumer eating behavior in real-life conditions. Conducted in 2022, at the restaurant “La Confluence” in Namur, with 60 participants, the experiment involved tracking the progression of a standardized meal, “Scallops in sauce with vegetables”. The collected data allowed for the calculation of variables such as bite count, applied force, meal duration, and quantity consumed. Through mathematical processing, insights into individual and group eating patterns were developed, with 39 usable datasets analyzed. Our first results show that the smart tray is capable of estimating the weight consumed and the number of bites with over 97% accuracy. Statistical analysis enabled the identification of four distinct groups of individuals based on five behavioral variables related to eating behavior. The smart tray could be used in hospitality establishments including cafeterias, restaurants, or brasseries, where it could serve as a valuable tool for monitoring meal nutrition. Further improvements will aim to enhance utensil and action recognition through artificial intelligence, which will also support a more detailed characterization of eating behavior. Full article

Drawing upon the TikTok platform, this study analyzes the media consumption of content dedicated to “Pandoro,” a typical sweet from Verona, Italy, identifying the most successful categories through a visual sociology approach. It then sets out to obtain a deeper understanding of the conceptualization of the sweet and the narration of Pandoro consumption among Gen Z, focusing on a small group of students in the city of Verona itself and verifying how elements of conservatism, traditionalism, and passivity emerge in the realization of content. What also appears interesting is the confirmation, which emerged from TikTok, that Pandoro is seen as an Italian symbol rather than a typical food associated with the city of Verona. Full article

The aim of the study undertaken was to determine the effect of a marinade using unpasteurised fruit vinegars and spirit vinegar, on the quality of raw poultry meat fresh (F) and after thawing (S). The raw material for the study was chicken breast muscle fillets. The meat was divided into two batches (F and S). This study evaluated the potency of unpasteurized quince, apple, grape and cherry fruit vinegars. The effect of the type of fruit vinegar used in the marinating process on the pH value of the meat was shown. Meat (F) marinated in fruit vinegars had a lower pH (4.55–5.04 pH) compared to the control group (5.65 pH). When poultry meat (F, S) was marinated in fruit vinegars, there was a brightening of colour, as evidenced by the higher values of the (L*) component. The use of vinegar in marinating poultry affected the rheological characteristics: hardness, elasticity, chewiness, gumminess, adhesiveness, cohesiveness, stringiness and bumpiness (p < 0.05) depending on the type of fruit vinegar used. The type of poultry meat used (F) and (S) in the marinating process had an effect (p < 0.05) on hardness, springiness, chewiness adhesiveness, and bumpiness, but not on their (p > 0.05) gumminess, cohesiveness, stringiness. Using unpasteurized fruit vinegars to marinate poultry meat can be an attractive alternative to commonly used marinades. Full article

Many consumers today pursue health goals to adopt healthier behaviors, and interest in promoting healthy eating habits in gastronomy is growing. Empirical evidence demonstrates that sensory cues (e.g., food color, food shapes, and background music) influence healthy eating behavior. However, the theoretical understanding of how sensory cues shape healthy food choices remains unclear. Specifically, this study develops the sensory–healthy eating model, a theoretical framework that explains how and when sensory cues influence healthy eating behavior (e.g., food choices and intake). By integrating related theories and empirical findings across interdisciplinary fields, we identify which sensory cues shape healthy eating and the psychological processes through which they operate. The theoretical model proposes that (1) sensory cues evoke cognitive (higher evaluation, lower potency, lower activity) and/or affective responses (positive valence, lower arousal), (2) these responses shape the perceived healthiness of foods based on their characteristics and quantity, and (3) the influence of perceived food healthiness on healthy eating behavior is stronger for consumers with health goals or motives. Our model provides a valuable framework for researchers and practitioners in marketing, food science, and gastronomy to promote healthy eating behavior. Full article

Pulsed Electric Fields (PEFs) are a technology increasingly used in the food industry for various purposes. However, their potential benefits as a pretreatment prior to the culinary preparation of a product have rarely been investigated. No previous study has investigated the use of PEFs in obtaining gazpacho, a typical Spanish dish. We aimed to evaluate the possibility of applying this technology in pretreating the vegetables used in gazpacho; furthermore, we evaluated its impact on the final product by comparing results with control samples. Applied at several different intensities (0.5–1.5 kV/cm and 4–40 kJ/kg), PEFs softened and decreased the vegetables’ water-holding capacity. In addition, this technique beneficially affected the organoleptic characteristics of gazpacho, increasing its consistency, improving its color (which became more reddish and intense), and enhancing its flavor. Moreover, the use of PEFs allowed us to reduce the amount of water in the mix, thus saving natural resources, concentrating nutrients, and decreasing energy consumption. Although further studies are required, PEFs can be considered a technology of interest in this productive sector. Full article

This paper describes the development of the Climate-Friendly, Healthy, Efficient Food Service (CHEF) curriculum at the City University of New York (CUNY). The program addresses a critical gap between growing industry demand for sustainability-trained workers and limited community college culinary education in these areas. Through collaborative design with industry partners, public agencies, and non-profit organizations, we created four core courses covering sustainable food service operations, culinary practices, food systems, and nutrition. The curriculum offers two implementation pathways: a 100 h continuing education credential and an Associate of Applied Science degree concentration. Industry partners have committed to supporting the program through internships and recognition of the credential in hiring decisions. This model demonstrates the feasibility of integrating comprehensive sustainability education into community college culinary programs while enhancing graduates’ career prospects in the expanding sustainable food service sector.

Aquafaba, the viscous liquid obtained from cooking chickpeas, has gained significant attention in the food industry due to its remarkable foaming and emulsifying properties, positioning it as a promising plant-based alternative to egg whites. This study investigated the effects of reheating on aquafaba’s functional properties, with a focus on its compositional concentration and molecular structural changes. Reheating was found to enhance both foaming and emulsifying capacities, with the most favorable results observed when the remaining liquid ratio was adjusted to 70–50%. Detailed molecular size analysis identified proteins and carbohydrates in the 30–100 kDa range as critical contributors to foam formation and stability. Furthermore, enzymatic treatments revealed that the synergistic interactions between proteins, pectins, and carbohydrates are key to aquafaba’s multifunctionality, enabling it to replicate the desirable properties of egg whites in various food applications. These findings not only advance our understanding of aquafaba’s molecular mechanisms but also demonstrate the potential of reheating as a practical strategy to optimize its properties for a wider range of culinary and industrial uses. This study underscores aquafaba’s versatility and highlights its role as a sustainable, plant-based ingredient capable of meeting the growing demand for vegan and allergen-free food products.

Insect proteins are suitable for human consumption and hold potential in the foodservice sector, where there is growing pressure to reduce traditional meat consumption, and this alternative could be explored through innovative gastronomy landscapes, such as by incorporating insect-based proteins into gourmet dishes. This study uniquely explored how young adults—specifically GenZ and Millennials (aged 18–30)—perceived and accepted insect-based products and whether their dietary habits aligned with sustainable principles. A mixed-methods approach was applied, including a cross-sectional study related to attributes of participants on insect products and sensory evaluation of insect and commercial products, to investigate awareness, acceptance, and sensory experiences. Key barriers included food neophobia and cultural resistance. The findings revealed a significant gap between awareness and behaviour: while 86% recognised insects as nutritious and 58% associated them with sustainability, only 18.6% have tried consuming them. This is a notable larger disparity compared to the adoption of other sustainable alternatives, such as vegetable meat based on peas, which have seen broader acceptance in recent years. Additionally, although 93.2% found products more appealing when their natural appearance is hidden, traditional insect-free products were still rated higher in taste, sweetness, and texture. Some insect-based products such as protein bars showed potential for greater acceptance than others. Bridging the awareness-behaviour gap requires targeted education, sensory improvement, and strategic marketing to emphasise nutritional and environmental benefits. Chefs could play a vital role by designing innovative menus that incorporate these products in familiar forms. This is demonstrated by successful examples where chefs have normalised unconventional ingredients, such as seaweed, overcoming cultural barriers and enhancing acceptance. Future studies should focus on expanding the diversity of participants, mapping gender differences, considering and improving the sensory properties of more products, and confirming the bioavailability of insects to promote wider acceptance of insect consumption.

A certain level of culinary sustainability was automatically built into many ancient cuisines due to scarcity in food supplies and, hence, optimal use of the available resources with minimal waste. The concept of sustainability in the global food systems today is much more complex, where the planetary limits to population growth and availability of food resources are leading to tremendous stresses on the overall conditions of the planet including the climate. Still, lessons from world cuisines across space and time may serve as a guide towards a more sustainable plant-forward cuisine in the future. In this essay, we highlight how a focus on gastronomy, especially gastronomic heritage, can provide a framework for a more sustainable cuisine. We see gastronomy as much more than related to cooking and fine dining but also referring to a complex understanding of the word, involving taste, lifestyle, meal culture, commensality, traditional knowledge, craftmanship, and food making. The Mediterranean Diet, traditional Japanese cuisine, and ancient Roman practices are discussed as examples. Full article

The science of gastronomy is a context-sensitive and qualitative application of human knowledge. While qualitative content analysis is a widely recognized research method, it is time-consuming, and its results heavily depend on the analyst’s expertise. This study addresses these challenges by employing automated content analysis (ACA), including tools like VOSViewer and AntConc, alongside qualitative methods from systemic functional linguistics (SFL). By analyzing 25 interviews with various professionals in gastronomy, the research aims to reduce subjectivity in interpreting data and uncover the essence of being a gastronomic chef. The findings highlight the complexity of a chef’s role, emphasizing creativity, collaboration, and innovation as key factors in delivering exceptional service and crafting the ultimate dining experience. Understanding a chef’s knowledge is crucial for enhancing service quality and comprehending consumer behavior, which is vital for service development. Full article

Food waste has been recognized as an environmentally damaging practice that is ethically wrong and does not contribute to sustainable development. According to the Food and Agriculture Organization of the United Nations, one-third of the food produced each year for human consumption is wasted. The use of additives can help to prevent food waste if they can overcome the problem of the limited supply of natural ingredients, increase the shelf life of food, and simplify cooking procedures. Therefore, the demystification of food additives, as well as their importance and uses, will help to increase consumers’ consciousness and enable them to make informed choices. This work reviews the physical/chemical properties of carrageenans, which are widely used as thickening and stabilizing agents in a wide range of everyday foods. This critical revision was made through bibliographic searches between January and May 2024 in the PubMed and Web of Science databases. The following keywords, in English, were used: “carrageenan*” and “additive*”, combined with the Boolean operator “AND”. Depending on the field of knowledge, another keyword was added to the search, such as, for instance, “chemical composition*”, “physical properties*”, “reology*”, “legal framework*”, “extraction*”, or “molecular cuisine*”. Additionally, the search allowed us to highlight how carrageenans can contribute to a better result in the final preparation of food and how they can be used in modern cuisine using simple molecular gastronomy recipes.

This paper examines a new artisanal food product made from bigleaf maple trees (Acer macrophyllum). These trees are indigenous to, and thrive in, the moist and mild climate of the Pacific Northwestern regions of the United States and Canada. Small producers have a new artisanal product from this historically valuable tree. The sap is collected from family-owned woodland trees to produce maple syrup. To better understand the gastronomic potential of bigleaf maple syrup, we conducted sensory evaluations with culinary professionals. In this study undertaken in Oregon, the syrup from three small independent producers was subjected to sensory hedonic and attribute assessments by 62 chefs. The results of the sensory assessments and the details of the testing methods and analysis are presented. This paper examines the agreement among the chefs and the implications for the culinary acceptance of this new artisanal product. We discuss in detail (1) the complexity of flavor; (2) the most likely use of bigleaf maple syrup in various foods or as a sweetener; (3) and the four most important reasons for purchasing bigleaf maple syrup consisting of both environmental and taste attributes.

The origin of a product, consumer familiarity, and purchasing identity are factors that affect the perception of cheese consumption. The present study aims at identifying consumers’ conceptualizations and attitudes towards local Greek cheeses of the North-Aegean Sea islands, such as Ladotyri, Graviera, Kasseri, Kaskavali, Melichloro, and Kalathaki, some of which have a Protected Designation of Origin (PDO) status, as opposed to cheeses of non-Greek origin, such as Cheddar, Regatto, and Gouda. Sensory and emotional attributes of local, local PDO, and imported cheeses, as well as drivers associated with consumers’ choice and acceptance above and beyond their sensory attributes, were studied using three methods: (a) flash profile to gain insight into the sensory positioning of products and description of samples; (b) qualitative analysis of focus groups to pinpoint consumer knowledge, preference, and consumption criteria; and (c) a new methodology for natural language processing and sentiment analysis of social media posts to determine consumer conceptualizations. Social media posts have proven to be a valuable source of linguistic and cultural data for cheeses. Local cheeses, including PDO products, were found to be linked to village life and family gatherings, home, tradition, and childhood memories, with saltiness and hardness being their main sensory attributes. Imported cheeses were linked to fast food, pizza, and snacking, with elasticity and gumminess as prominent sensory qualities. The main criteria for purchase were intended usage and versatility, taste and texture, price, and familiarity. The findings provide key sensory attributes, information about consumer purchasing criteria, and relevant vocabulary for the promotion of cheeses as agri-food and gastronomic identity key products.
