NIZO: Expert vs consumer sensory panels: Best of both worlds?
If consumers don't like a product, they won't buy it. Testing with sensory panels can help determine consumer liking, so what kind of sensory panel should manufacturers go for?
Enhancing Odor Analysis with Gas Chromatography–Olfactometry (GC-O): Recent Breakthroughs and Challenges | Journal of Agricultural and Food Chemistry
Gas chromatography–olfactometry (GC-O) has made significant advancements in recent years, with breakthroughs in its applications and the identification of its limitations. This technology is widely used for analyzing complex odor patterns. The review begins by explaining the principles of GC-O, including sample preparation, separation methods, and olfactory evaluation techniques. It then explores the diverse range of applications where GC-O has found success, such as food and beverage industries, environmental monitoring, perfume and aroma development, and forensic analysis. One of the major breakthroughs in GC-O analysis is the improvement in separation power and resolution of odorants. Techniques like rapid GC, comprehensive two-dimensional GC, and multidimensional GC have enhanced the identification and quantification of odor-active chemicals. However, GC-O also has limitations. These include the challenges in detecting and quantifying trace odorants, dealing with matrix effects, and ensuring the repeatability and consistency of results across laboratories. The review examines these limitations closely and discusses potential solutions and future directions for improvement in GC-O analysis. Overall, this review presents a comprehensive overview of the recent advances in GC-O, covering breakthroughs, applications, and limitations. It aims to promote the wider usage of GC-O analysis in odor analysis and related industries. Researchers, practitioners, and anyone interested in leveraging the capabilities of GC-O in analyzing complex odor patterns will find this review a valuable resource. The article highlights the potential of GC-O and encourages further research and development in the field.
Assessment of Protein Quality and Digestibility in Plant-Based Meat Analogues | Journal of Agricultural and Food Chemistry
In this first work, commercial steak-like (n = 3) and cured meat (n = 3) analogues with different legume and cereal formulations were studied and compared to their animal-based (n = 3) counterparts. Plant-based products showed lower protein content than meat controls but a good amino acidic profile even though the sum of essential amino acids of plant-cured meats does not fulfill the requirements set by the Food and Agriculture Organization for children. A comparable release of soluble proteins and peptides in the digestates after in vitro digestion was observed in meat analogues as meat products, whereas the digestibility of proteins was lower in plant-based steaks and higher in plant-based cured meats than their counterparts. The overall protein quality and digestibility of products are related to both the use of good blending of protein sources and processes applied to produce them. An adequate substitution of meat with its analogues depends mostly on the quality of raw materials used, which should be communicated to consumers.

Making Scents of it All: Intellectual Property Dilemmas in Olfactory Art and the Concerns of Olfactory Artists as Digital Olfaction 'Stinks Up' the Scene - NYU Journal of Intellectual Property & Entertainment Law
In recent years, the digital olfaction industry has experienced significant growth, spurred by advancements in Artificial Intelligence (AI) and other emerging technologies that are applicable to the digitization of scent. Two distinct “branches” of digital olfaction have developed in this expansion: one related to the digital detection and analysis of odor and another focused on […]
Un texte de Stéphane Cariou, Jean-Michel Guillot, Elisabeth LordLes odeurs, quelques soient leurs provenances, peuvent avoir un impact sur la santé des populations exposées, tant au plan physiologique que psychologique. L’analyse des odeurs est toutefois complexe, car outre le fait que chaque individu possède des habiletés très personnelles à percevoir une odeur, agréable ou mauvaise, intense ou non, une odeur est perçue de manière instantanée et cette perception évolue dans le temps. Les object
Sentons-nous le goût des aliments uniquement avec notre langue ?
Les bourgeons gustatifs, les structures qui nous permettent de sentir le goût, ne se trouvent pas que sur la langue. Les scientifiques en ont identifié dans d’autres parties du corps.
Degustar los alimentos es una compleja experiencia multisensorial en la que intervienen las emociones, nuestra historia personal o incluso el poso de la cultura heredada.
