Dietary Artificial Sweeteners: From Chemical Transformation in Food to Gut Microbial Processing

ChemFoodChem, EarlyView.
This review article unites classical and recent findings on the stability of artificial sweeteners in food. The focus is on ten sweeteners approved in the European Union: their chemical stability during processing and storage, individual degradation products, and their interactions with the intestinal microbiota.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Ecotoxicity Tests for Compost Applications

Ecotoxicology and Environmental Safety, 2001
Interest in the ecological effects of composting has been growing recently. However, no established methods are available for testing the toxicity of composted materials. Despite this, international and national quality requirements define that compost shall not contain any environmentally harmful substances. Safety requirements have to be fulfilled if
