Abstract
The formation and occurrence of acrylamide in carbohydrate-rich foods has been extensively studied over the course of the past few decades. However, the emergence of plant-based meat alternatives presents a new challenge in this field. The aim of this study was to evaluate the levels of acrylamide in commercially available plant-based meat alternatives before and after heat treatment. Trace levels of acrylamide were detected in all samples before heat-treatment, while the concentrations increased in 11 samples out of 16 after heat-treatment. The highest concentration of acrylamide increased from 65.7 ± 6.6 µg kg−1 before to 119 ± 12 µg kg−1 after heat-treatment. Principal component analysis (PCA) indicated that besides macronutrient composition, the use of additives and processing techniques have a strong influence on acrylamide formation in plant-based meat alternatives. The latter was supported by the analysis of self-made meat alternative models that were prepared using only the base ingredients.
