The use of natural biodegradable products as an alternative to synthetic chemicals has shown remarkable improvements in maintaining fruit quality
Synthetic chemicals are used currently to control postharvest diseases but consumers worry about the chemical residues they leave on fruit their environmental impact

Nixdorf invented a new test that analyzes the chemical composition of coffee. She uses liquid chromatography a process that creates a unique fingerprint stain for each ingredient.
First brewed coffee is sent through a pressurized pump. The coffee passes through a special paper filter.
For now the chromatography test can be done only in a lab. Nixdorf recommended that consumers stick to whole-bean coffee

The lead researcher of the new study Dr. Kirsten Brandt at Newcastle University has been studying naturally occurring chemicals found in certain vegetables called polyacetylenes for many years.
This however is only the first step in testing any potential new anticancer chemicals. In their study Brandt and her colleagues also used a mouse model as proxy for humans
Because of the chemical composition of the polyacetylenes she predicts that cooking them in fat may cause more to be lost into the fat than preparing the carrots in water by boiling or steaming.
As with any plant carrots are a combination of hundreds of different chemicals including beta-carotene
Dissecting exactly which chemicals in plants are observed responsible for health benefits is notoriously tricky.##oewe may be able to figure this out as white carrots are rich in polyacetylenes
Sarah hopes that contrasting these two varieties of carrots may allow the research team to pinpoint the chemicals that are responsible for their early cancer-protective findings
and make sure that by looking at polyacetylenes they are focusing their research on the right chemicals.
