An improved extraction method for acrylamide determination in fruit and vegetable chips through enzyme addition

Area of Science:

• Food Chemistry
• Analytical Chemistry
• Toxicology

Background:

• Acrylamide is a potential carcinogen found in fried and baked foods.
• Accurate analysis of acrylamide in processed foods is crucial for food safety.
• Existing methods for acrylamide extraction from certain food matrices can be challenging.

Purpose of the Study:

• To develop and validate an improved enzyme-addition method for pretreating fried fruit and vegetable chips for acrylamide analysis.
• To assess the efficiency and accuracy of the modified method compared to existing procedures.
• To determine acrylamide content in marketed fruit and vegetable chip products.

Main Methods:

• Modification of the FDA method by incorporating digestive enzymes (diastase, pepsin) for sample pretreatment.
• Extraction of acrylamide from various fried fruit and vegetable chips, including high-starch and high-mucin products.
• Quantification of acrylamide using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS).

Main Results:

• The enzyme-addition method effectively overcame filter clogging issues during sample extraction.
• High recoveries of acrylamide (90.3-105.5% and 99.8-102.2%) were achieved with the modified method.
• The method demonstrated low limits of detection (LOD) and quantification (LOQ), comparable to or better than the original method.
• Acrylamide levels were determined in 36 commercial chip products, meeting EU regulatory standards.

Conclusions:

• The enzyme-addition method provides a robust and efficient approach for acrylamide analysis in fried fruit and vegetable chips.
• This improved method facilitates accurate acrylamide determination, contributing to enhanced food safety monitoring.
• The validated method adheres to European Union regulations for critical analytical parameters.
