An in-depth understanding of consumers’ decision-making in the sustainable food consumption is a crucial prerequisite for effective environmental, social and governance (ESG) management. The heuristic-systematic (HS) model appears to be useful for deepening our understanding of it. This study examines consumer (i.e., 600 Millennials and Generation Z (MZ) consumers in the middle-income class) reaction to the HS stimuli in the green domain. With eco-friendly eggs and plant-based eggs in the experiments, the MANOVA results showed that overall, S outperformed H in many aspects, but it was important to deliver real benefits that people can feel more closely everyday life.

Healthy and tasty food choices are needed for the rapidly increasing demographic of older adults to promote healthy ageing and to prevent conditions such as malnutrition. This study aimed to design soup recipe specifications using an innovative combination of approaches and interactions with different stakeholders, notably culinary chefs, culinary students, scientific experts, and target consumers. These food products were designed to be adapted to healthy, community-living French adults, between 55 and 75 years. Importantly, including adults under 60 further explores their food priorities and acceptance for foods that can impact future health. In short, the employed co-design approach integrated scientific literature observations and recommendations, consumer survey responses (including modified Food Choice Questionnaire) and focus groups with food tasting with the participation of multiple actors (older adults, food science experts, and culinary chefs). In terms of results, a multi-constraint specification for chunky soups was created, highlighting key nutritional, sensorial, food oral processing, and culinary goals. This was then interpreted by a trained culinary chef, with soup ingredients and recipes tailored to multiple criteria specifications. Chunky soups are not commonly consumed by French older adults, however it was found to be appealing and acceptable by target consumers. This co-design approach integrates multiple constraints, offering a framework for developing food products tailored for long-term adoption among specific populations, such as older adults.

3D food printing technology allows for the customization of food textures, shapes, and compositions, but challenges arise from the diverse properties of food matrices. Ink formulations must balance flowability during extrusion with structural stability. This study investigates the potential of Ora-pro-nobis (OPN) mucilage to enhance the structural integrity and printing precision of 3D-printed food by examining its impact on printing precision and rheological behavior. Food inks were formulated with varying proportions of protein (P), OPN mucilage (M), and starch (S), with total solids ranging from 13.7% to 42.7%. Of the formulations tested, seven were deemed printable. All printable inks exhibited non-Newtonian, pseudoplastic behavior. Thixotropic analysis showed that mucilage was crucial in preventing structural collapse after printing. The absence of mucilage (80P0M20S) resulted in the lowest recovery rate (∼25%), while increasing mucilage concentration improved the recovery rate, reaching 96% with 10% of its mucilage solids (70P10M20S). Similar trends were observed in printing accuracy. Reducing mucilage from 10% to 2% in samples 70P10M20S and 70P2M28S decreased printing accuracy from 95.5% to 89.34%, and 73.38% without mucilage (80P0M20S). Incorporating OPN mucilage in formulations enhanced ink elasticity, viscosity recovery rate, and printing accuracy, underscoring its crucial role in 3D food printing.

In our time, wine-related industries express a growing demand for understanding new ideas about wine. This article explores how professional wine tasters develop their knowledge. Based on the idea of bildung as hermeneutic interpretation, we argue that there are three dominant ideas about how knowledge of wine can be approached: first, as an acquired canon; second, as a systematic tool; and third, as a search process. The intertwinement of these perspectives is exemplified by four autobiographical stories about experiences of learning, working with, and developing wine knowledge. One story is the first author's own autobiography; the others are published works by influential wine tasters. Autobiographical stories add a novel humanistic approach to explorations of wine knowledge, focusing on interpretation of experiences.
In the discussion, the three different approaches to knowledge acquisition are related to how they support our understanding of different aspects of wine. We argue that canonic and systematic knowledge tends to be limited to conventional and technical aspects, while knowledge of the individuality of more unconventional wines and their aesthetic aspects is acquired through a search process. With increased influences of humanistic expressions in the world of wine, a greater focus on knowledge-seeking approaches to wine is required.

In southern Brazil, colonial cheese is a very popular traditional dairy and plays significant economic and cultural roles. Innovation in traditional foods is crucial for continued market growth. Marinating cheeses in wine is a known practice, however the use of vinegar is traditional on informal scale in southern Brazil, but little explored. This study aimed to evaluate the impact of marinating colonial cheese in wine and vinegar during ripening. Colonial cheeses were immersed whether wine or vinegar and ripped for 30 days. Colour, moisture, texture and pH parameters were evaluated during the ripening period and cheeses in the end of 30-day maturation were subjected to acceptance, perception of attributes and evoked emotions analyses. Drivers of purchasing were also explored. Cheeses immersed in vinegar showed a greater loss of moisture and a decrease in pH. The surface of cheeses immersed in wine showed a dark and reddish color immediately after immersion in wine, with gradual darkening until the tenth day of ripening. Immersion of the product into vinegar implied on cheeses with surface with a less intense coloration (red and dark). Hardness increased through ripening and were higher on marinated samples. The control cheeses showed greater acceptance and evoked positive emotions, while the experimental cheeses evoked more negative emotions. Cheeses marinated in wine and vinegar incorporated characteristic aroma and flavors of the beverage used. Hedonic aspects and the presence of new flavors were the main drivers of purchasing the cheeses. Thus, immersing cheese in wine or vinegar impacts the maturation process, providing different effects on physicochemical and sensorial features of the product.

Food and gastronomy can significantly influence a country's domestic and foreign diplomatic settings or strategies. Either from the perspective of cultural diplomacy, diplomatic relationships, benefits attraction, and soft/hard power exercise. This involves the mobilization of national cuisines, traditions, food cultures, and food power ideas to create positive perceptions of a country or community, leading to its engagement in the global gastronomic and food systems. However, the conceptual and epistemological frameworks of those mobilisations frequently remain ambiguous from the academic, practical, and policymaking perspectives, leading to imprecisions about their configurations.
Objectives
This systematic review aims to organise the architectural and conceptual features of the “taste diplomacies” (gastrodiplomacy, culinary diplomacy, and food diplomacy) and their actions at the intersection of gastronomy and diplomacy. It clarifies key concepts, allowing solid intersections between cultural aspects and international relations in policymaking, scientific advancements, and social/cultural events. The review seeks to clarify the core features of food-related foreign public policies.
Methods
A 47-article Systematic Literature Review (SLR) has been carried out with PRISMA guidelines. The search was performed through Google Scholar, Open Alex, Scopus, Web of Science, and EBSCO Host.
Key findings
The findings indicate the novelty of the concepts and the ongoing process of conceptual and theoretical stabilisation, highlighting a recent chronology and conceptual tensions in scientific production. The conceptual genealogy originates from two authors who, in their definitions, have paved the way for conceptual interchangeability.
Conclusions
The terms “gastrodiplomacy”, “culinary diplomacy”, and “food diplomacy” have been solidified as a) the practices of global promotion of food products/foodways/national cuisines expressively or tacitly associated with sovereign States' cultural diplomacy/nation branding policies and soft power-driven actions, b) the utilisation of national food and foodways in ceremonial and diplomatic meals, and c) a state's participation in the world food movements, including food security measures and humanitarian food aid in times of conflicts, respectively.

This study evaluated the addition of bamboo shoot powder to processed cheese (Requeijão), focusing on its physicochemical and technological properties. The bamboo shoots were divided into outer and inner parts, processed into powder, and incorporated into Requeijão. Four samples with varying amounts of bamboo powder were compared to four samples made with commercial bamboo fiber. The samples containing 3% bamboo powder exhibited an 80% reduction in melting behavior compared to control samples. Additionally, the sample with 3% powder from the outer bamboo part demonstrated greater hardness (10 N) compared to the commercial fibers (∼5.7 N). Bamboo can be used without extensive purification, contributing positively to the healthiness of Requeijão, becoming an accessible source of nutrients such as dietary fiber and protein for the population.

Saffron possesses a valuable composition of chemicals and distinct sensory properties. This article examines the chemical composition, sensory qualities, and the importance of detecting adulteration within saffron. Recent studies have shown that saffron contains several bioactive substances, such as safranal, picrocrocin, and crocin; these constituents offer various health benefits due to their antioxidant, neuroprotective, and anti-inflammatory effects. The spice's colour comes from water-soluble apocarotenoids, namely the crocin and crocetin sugar esters, which confer the food yellow hues. Picrocrocin is a monoterpene glucoside responsible for the bitter taste of this spice. On the other hand, safranal is the volatile component that gives the spice's aroma. The food industry values saffron's flavour and vivid colour, often using it to make high-end products and functional foods.
Based on minimal quality requirements, the International Organization for Standardization (ISO) has developed a system for classifying saffron in merchandise categories. However, there have been concerns about the accuracy of the results obtained through ISO methods. Because of this, research has been conducted to determine saffron's safranal and crocin levels using the ISO methods compared to other methods.
In summary, saffron is a valuable source of bioactive constituents, frequently used to manufacture functional foods. However, it is imperative to establish and employ reliable methods to identify adulteration so that consumers benefit from the quality and authenticity of this precious spice. Implementing these techniques will help maintain high standards in the food industry, thus ensuring public health protection and consumer confidence.
藏红花具有珍贵的化学成分和独特的感官特性。本文探讨了藏红花的化学成分、感官品质以及检测掺假的重要性。最近的研究表明，藏红花含有多种生物活性物质，如沙弗拉醛、小红花苷和藏红花苷；这些成分具有抗氧化、保护神经和消炎的作用，对健康有多种益处。这种香料的颜色来自水溶性类胡萝卜素，即 crocin 和 crocetin 糖酯，它们赋予食物黄色。微辛是一种单萜葡萄糖苷，是这种香料苦味的来源。另一方面，藏红花醛（safranal）是一种挥发性成分，赋予这种香料芳香。食品工业重视藏红花的味道和鲜艳的颜色，经常用它来制作高端产品和功能性食品。根据最低质量要求，国际标准化组织（ISO）制定了一套藏红花商品分类系统。然而，人们对通过 ISO 方法得出的结果的准确性表示担忧。总之，藏红花是一种宝贵的生物活性成分来源，常用于生产功能性食品。然而，当务之急是建立并采用可靠的方法来鉴别掺假行为，从而让消费者从这种珍贵香料的质量和真实性中获益。采用这些技术将有助于保持食品行业的高标准，从而确保公众健康保护和消费者信心。

The spice's colour comes from water-soluble apocarotenoids, namely the crocin and crocetin sugar esters, which confer the food yellow hues. Picrocrocin is a monoterpene glucoside responsible for the bitter taste of this spice. On the other hand, safranal is the volatile component that gives the spice's aroma. The food industry values saffron's flavour and vivid colour, often using it to make high-end products and functional foods.</div><div>Based on minimal quality requirements, the International Organization for Standardization (ISO) has developed a system for classifying saffron in merchandise categories. However, there have been concerns about the accuracy of the results obtained through ISO methods. Because of this, research has been conducted to determine saffron's safranal and crocin levels using the ISO methods compared to other methods.</div><div>In summary, saffron is a valuable source of bioactive constituents, frequently used to manufacture functional foods. However, it is imperative to establish and employ reliable methods to identify adulteration so that consumers benefit from the quality and authenticity of this precious spice. Implementing these techniques will help maintain high standards in the food industry, thus ensuring public health protection and consumer confidence.</div></div>","PeriodicalId":48594,"journal":{"name":"International Journal of Gastronomy and Food Science","volume":"38 ","pages":"Article 101067"},"PeriodicalIF":3.2,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142702113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Evaluating the transfer of culinary skills from educators to students is essential but challenging due to the subjective nature of traditional assessment methods like direct observation. This study proposes using deep learning and image analysis, particularly convolutional neural networks (CNNs) such as VGG-16, to objectively and automatically evaluate the skill transfer by identifying and quantifying visual differences between student and instructor-prepared dishes. The results show that CNNs can effectively capture critical visual features, offering a more consistent and scalable assessment approach. However, challenges remain, including sensitivity to image quality and discrepancies between automated evaluations and human judgments. These findings highlight the need for further refinement of models and expanding datasets to better capture the diversity of real-world culinary outputs. This research lays the foundation for integrating advanced analytical techniques into culinary education, with future work focusing on developing specialized datasets, fine-tuning models, and standardizing protocols to enhance the accuracy and reliability of automated culinary assessments.
