e0“Though 5-hydroxymethyl-2- furaldehyde is primarily responsible for the deleterious effects of autoclaved fructose, a number of other decomposition products compound the toxicity”
e1“fructose media sterilized by filtration are clearly beneficial for the growth of intact plants of Cruciferae”

Other claims from this paper (12)
- Intervention effect Filter-sterilized fructose medium benefited growth of intact Cruciferae.
- Observation Fructose decomposed faster during autoclaving than glucose or sucrose.
- Mechanism Plants suffered on autoclaved fructose media because toxic degradation products accumulated.
- Observation Early fructose breakdown products absorbing near 230 nm were apparently harmless.
- Intervention effect Prolonged heating shifted the absorption maximum to around 285 nm.
- Observation 5-hydroxymethyl-2-furaldehyde was toxic in the 10-4 M range.
- Observation Hydroxyacetyl furan was toxic in the 10-4 M range.
- Method / resource Thin layer chromatography separated at least ten decomposition-product hydrazones.
- Intervention effect Cyclic adenosine monophosphate did not relieve toxicity of autoclaved fructose.
- Association The adverse fructose-medium effect in crucifers was unrelated to sugar chelation.
- Observation Medium acidification during autoclaving contributed only a minor effect.
- Mechanism Other decomposition products added to the toxicity of autoclaved fructose.
