Predicting Spatial Variability of PR Protein Concentration in White Grape Juice Using UAV Multispectral Data and Machine Learning
Background: Pathogenesis-related (PR) proteins, primarily thaumatin-like proteins (TLPs) and chitinases, are the principal cause of protein haze formation in white wines, increasing bentonite requirements and affecting winemaking efficiency. However, evaluating their spatial variability before harvest remains challengi...
