  • Title: Influence of Potato Crisps Processing Parameters on Acrylamide Formation and Bioaccesibility.
    Author: Martinez E, Rodriguez JA, Mondragon AC, Lorenzo JM, Santos EM.
    Journal: Molecules; 2019 Oct 23; 24(21):. PubMed ID: 31652876.
    Abstract:
    A fractional factorial design was used to evaluate the effects of temperature, frying time, blanching treatment and the thickness of potato slices on acrylamide content in crisps. The design was used on freshly harvested and four-month stored potatoes. The critical factors found were temperature and frying time, and the interaction between blanching treatment and slice thickness. Once frying conditions were selected, an acrylamide content of 725 and 1030 mg kg-1 was found for non-stored and 4-month stored tubers, with adequate textural parameters in both cases. The difference in concentration is related to storage conditions, which must be controlled in order to control acrylamide levels. Bioaccesibility studies demonstrated that acrylamide concentration remained at 70%, and reductions took place mainly at the intestinal phase, as a result of reaction with nucleophilic compounds.
