High‐throughput methods for measuring protein extractability in sugar beet ( <scp> <i>Beta vulgaris</i> </scp> L.) leaves

This study provided high-throughput methods for assessing leaf protein content and extractability in sugar beet. The strong correlation between total nitrogen and true protein confirms their reliability for protein quantification. These findings aid efficient screening of sugar beet germplasm for improved leaf protein yield, contributing to sustainable leaf valorization. © 2025 The Author(s).
