The increasing popularity of social media and the growth of gourmet food culture have elevated molecular gastronomy as a unique dining experience that enhances consumers’ perceptions of value through innovative food presentation and sensory marketing strategies. This study investigates consumer acceptance of molecular gastronomy by utilizing the value–attitude–behavior (VAB) model and the Theory of Planned Behavior (TPB). We examine the interplay between utilitarian and hedonic values, product innovation, and sensory stimulation to understand consumer reactions and attitudes toward molecular gastronomy. Through convenience sampling, we surveyed individuals who had experienced molecular gastronomy, collecting 407 valid responses, with a response rate of 95.3%. Our findings reveal that both utilitarian and hedonic values significantly influence consumers’ attitudes (β = 0.635, p < 0.01; β = 0.750, p < 0.01). Attitudes, perceived behavioral control, and sensory stimulation play crucial roles in shaping behavioral intentions (β = 0.770, p < 0.01; β = 0.719, p < 0.01; β = 0.791, p < 0.01). Although subjective norms and product novelty also have positive effects on intentions, their impact is less significant (β = 0.511, p < 0.01; β = 0.416, p < 0.01). These insights suggest that practitioners in the dining industry should prioritize utilitarian value, hedonic appeal, consumer attitudes, perceived behavioral control, and sensory experiences when creating and marketing molecular gastronomy dishes. This research not only enhances our understanding of consumer behavior within this innovative culinary domain but also offers practical strategies for boosting market acceptance and engagement with such avant-garde dining experiences.

Gluten-free baked goods exhibit reduced texture and taste characteristics compared to their gluten-containing counterparts. As a result, there is a renewed interest in the fermentation of gluten-free cereals with lactic acid bacteria, which is associated with an improvement in the final baked goods. Quinoa is garnering growing attention due to its different nutrients and bioactive substances, and it is notably employed to build gluten-free goods. In the present study, quinoa flour was fermented with Enterococcus strains (E. gallinarum SL2 and E. mundtii SL1), and further used in the manufacturing of gluten-free muffins. Several analyses were performed on the obtained sourdoughs and muffins, including a viscosity study, a textural and sensory analysis, and a polyphenol, organic acid, and carbohydrate content analysis. The results showed that the fermented quinoa flour exhibited enhanced nutritional value, with increased levels of organic acids such as lactic and acetic acid, as well as improved polyphenol content. The sensory and textural analyses revealed that both Enterococcus strains positively impacted the sensory characteristics and texture of the muffins. Notably, muffins prepared with E. mundtii SL1 demonstrated superior elasticity and overall taste. These results suggest that fermentation with these strains can significantly improve the nutritional profile and sensory quality of gluten-free baked goods, offering a promising approach for the development of healthier and more appealing gluten-free products.

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.

Enterococci, known for their resilience, are commonly found in food, the environment, and the gastrointestinal tracts of humans and animals. In recent research, six strains of enterococcus were isolated from bat guano. These include Enterococcus mundtii SRBG1, Enterococcus gallinarum SRBG3, Enterococcus faecium SRBG2, Enterococcus casseliflavus EC1, and Enterococcus devriesei CAU 1344. Identification was done using 16S DNA analysis. Each strain underwent evaluation for its technological properties (such as tolerances to various NaCl concentrations and temperatures, as well as amylolytic, β-galactosidase, lipolytic, and proteolytic activities, and EPS production) and selected probiotic properties (including safety profile, resistance to 0.3 percent bile salts and gastric juice with a pH of 2.5, lysozyme tolerance, and antibacterial and antibiofilm activities against four foodborne pathogens). The results were analyzed using Principal Component Analysis. This analysis revealed that E. mundtii SRBG1 and E. gallinarum SRBG3, followed by E. faecium SRBG2, were most closely associated with a broad range of technological characteristics and were subsequently used for fermenting skimmed milk. The rheological properties of the samples indicated a shear-thinning or non-Newtonian behavior. Furthermore, during storage of the fermented milk at 4 °C over periods of 1, 7, 14, and 21 days, there were no significant changes in bacterial count (at around 7 log₁₀ CFU/mL) and pH when fermented with the three evaluated strains.

Petroselinum crispum (Mill) Fuss is an aromatic plant belonging to the Apiaceae family and used in gastronomy as a spice. Several studies have been developed in leaves but studies are limited in seeds, especially the essential oils obtained from seeds. The aim of this study was to determine the phytochemical profile of the volatile compounds of this essential oil by gas-chromatography–mass spectrometry (GC-MS) in order to evaluate its phytotoxic activity on Lactuca sativa seeds and to carry out an in silico analysis on the target enzyme of the herbicide glyphosate 5-enolpyruvylshikimate 3-phosphate synthase (EPSP). The essential oil was obtained by steam distillation for two hours and then was injected into a GC-MS, the phytotoxic assay was carried out on Lactuca seeds and the in silico evaluation on the EPSP synthase focused on the volatile compounds similar to glyphosate, docking analysis, and molecular dynamics to establish the protein–ligand stability of the most active molecule. The chromatographic analysis revealed 47 compounds, predominated by three compounds with the most abundant percentage in the total content (1,3,8-ρ-menthatriene (22.59%); apiole (22.41%); and β-phellandrene (15.02%)). The phytotoxic activity demonstrated that the essential oil had a high activity at 5% against L. sativa seed germination, inhibition of root length, and hypocotyl length, which is comparable to 2% glyphosate. The molecular docking on EPSP synthase revealed that trans-p-menth-6-en-2,8-diol had a high affinity with the enzyme EPSP synthase and a better stability during the molecular dynamic. According to the results, the essential oil of P. crispum seeds presented a phytotoxic activity and might be useful as a bioherbicide agent against weeds. Full article

Magic and dining have long been popular forms of entertainment. What is more, both involve some kind of transformation, and yet while the more theatrical aspects of dining have grown in popularity in recent decades, there is a surprising paucity of magical food and beverage experiences out there. In this article, we trace the historical appearance of food and drink and culinary items in the performance of magic. We also review some of the more magical elements of food design that have appeared on menus in bars and restaurants in recent years. We introduce the edible lightbulb dish from the menu at Kitchen Theory Chef’s Table and link it to the stage magic of Derren Brown. We also discuss some of the reasons as to why magical food experiences might be rare in the context of dining. In so doing, our hope is to highlight an intriguing area for future research and innovation. Along the way, we identify some possible candidate approaches for the introduction of edible magic onto the menu in the context of modernist cuisine. Full article
