Formation of acrylamide in potato products and its dietary exposure
Acrylamide is formed during baking and frying of potato and cereal foodstuffs and is considered as a suspected human carcinogen. Potatoes are particularly susceptible to the formation of this process contaminant. Due to their frequent consumption, these products moreover contribute significantly to …

Frying of potato crisps - an investigation aiming at reduction oil content and acrylamide formation
Reducing oil content, minimizing any carcinogenic acrylamide in the high temperature frying process for potato crisps, and producing good products with considerable crispiness and acceptable color were the objectives of this research. Vacuum frying with pre-treatment of potato crisps was …

Advancing fast relaxation imaging to determine protein stability and folding kinetics on poly(n-isopropyl acrylamide) films
Several studies have reported the use of the thermo-responsive polymer PNIPAM to capture and release cells or proteins for medical purposes; however, this assumes that PNIPAM does not perturb the stability of biomolecules. Previous analytical and spectroscopic techniques have not been able to …
