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.

Pectin-rich dietary fiber from ripe papaya increases Lactobacillus abundance and reduces the formation of aberrant crypts in rats submitted to chemically-induced colorectal cancer.

Pectins are a class of highly fermentable dietary fibers that modulate the gut microbiota, with biological effects that vary depending on ripening stage and molecular structure. Th... Read full abstract on PubMed →
