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.

Development and validation of a high-performance liquid chromatography method for the determination of diacetyl in beer using 4-nitro-o-phenylenediamine as the derivatization reagent.

Diacetyl is a natural byproduct of fermentation and known to be an important flavor compound in many food products. Because of the potential undesirable effects of diacetyl on heal... Read full abstract on PubMed →
