Unsupervised Recovery of Food Taxonomy from Volatile Compound Profiles: A UMAP Analysis of 450 Ingredients

Without supervision or human-coded labels, a UMAP projection of 7,464 volatile compounds across 450 ingredients reproduces conventional food categories — and surfaces cross-category molecular bridges that traditional culinary intuition misses.

2017 PloS one threshold study

Evidence for a shape-based recognition of odorants in vivo in the human nose from an analysis of the molecular mechanism of lily-of-the-valley odorants detection in the Lilial and Bourgeonal family using the C/Si/Ge/Sn switch strategy.

We performed an analysis of possible mechanisms of ligand recognition in the human nose. The analysis is based on in vivo odor threshold determination and in vitro Ca2+ imaging ass... Read full abstract on PubMed →

Off-odor compounds responsible for quality loss of minimally processed baby spinach stored under MA of low O2 and high CO2 using GC–MS and olfactometry techniques

Strong off-odor development is still one of the major problems associated with quality loss of baby spinach stored in MA with low O2 and high CO2. Freshness has been generally eva... Read full abstract on PubMed →
