Impact of aqueous extracts of Turkish wild edible plants on acrylamide formation in potato crisps

Abstract

Background: Antioxidants have the ability to influence acrylamide formation. This study aimed to evaluate the impact of aqueous extracts of six wild edible plants on the acrylamide formation in potato crisps. Methods: Sliced potatoes were submerged in the plant extracts at a concentration of 0, 5, and 10 g/L for 1, 5, and 10 min. Before being fried and their acrylamide levels were calculated by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). Results: Aqueous extract of ribwort plantain was found the most effective trial at 10 g/L for 5 min because it reduced acrylamide concentration by 57% compared to control without significantly affecting potato crisps’ sensory and color parameters (p>0.05). The aqueous extract of shepherd’s-needle yielded the highest Total Antioxidant Capacity (TAC) in 2,2′-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid; ABTS) and Cupric ion Reducing Antioxidant Capacity (CUPRAC) assay, the highest Total Phenolic Content (TPC), and Total Flavonoid Content (TFC). Similarly, no significant correlation was found between TAC, TPC, and TFC of watery plant extracts with acrylamide level of potato crisps produced after immersion of these extracts (at 5 g/L for 5 min). Conclusion: Wild edible plants have the potential to be used for acrylamide reduction in potato crisps.
