Summary
This study examines the historical analysis of coffee adulteration in the 1850s. It questions the methods and objectivity used, impacting early food safety regulations.
Area of Science:
- Food Science
- History of Science
- Public Health
Background:
- The Lancet's Analytical Sanitary Commission (ASC) extensively analyzed coffee for adulteration between 1851-1854.
- Arthur Hill Hassall's work with microscopy in coffee analysis influenced food purity investigations.
Observation:
- Hassall's techniques were applied to other food and drink analyses.
- His findings led to the first parliamentary committee on food purity in 1855.
Findings:
- This article challenges the selection criteria for analyzed foodstuffs by the ASC.
- It questions the supremacy of microscopy over chemical analysis for detecting adulteration.
- The extent of coffee adulteration in the mid-19th century is re-evaluated.
Implications:
- The study revisits the historical narrative of scientific objectivity in public health debates.
- It offers a critical perspective on the foundation of early food safety legislation.
- Re-evaluates the role of coffee adulteration in driving food control reforms.
