arXiv Preprint Details OCR Workflow for Sodium Screening of South African Foods

A cross-listed arXiv preprint describes a conservative, OCR-driven pipeline that reads food packaging images to check sodium and salt levels against South Africa's R214 limits. The authors note that screening decisions depend on establishing product identity, extracting nutrition facts panel evidence, choosing a reporting basis, and applying category-specific thresholds. The work frames automated label reading as a practical aid for regulatory compliance checks rather than a fully autonomous decision tool.
