Complementary assessment of nano‐packaged garlic properties by electronic nose

Food Science &Nutrition, Volume 12, Issue 7, Page 5087-5099, July 2024.
Garlic inoculated into three fungi and stored in two types of packaging. The aromas' profile of each treatment composition was detected by E‐Nose. The changes in physical, chemical, and mechanical traits were inspected. PCA, LDA, and BPNN were implemented to analyze volatile fingerprints of garlics.
