Background:
In this article the relationship between lipophilic grape seed proanthocyanidin (LGSP) and acrylamide formation in potato-based products was investigated. The acrylamide, reducing sugar, asparagine, and 3-aminopropionamide contents were determined by high-performance liquid chromatography mass spectrometry (HPLC-MS). Sensory evaluation was used to evaluate the quality of the products.
Results:
The results showed that LGSP presented greater inhibition effect on the acrylamide formation than the commonly used commercial antioxidants. Furthermore, 81.5% and 84.7% of acrylamide was reduced in potato crisps and French fries after adding 0.1% and 0.05% LGSP (w/w) in palm oil, respectively. When the concentrations of LGSP were less than 0.1%, there was no significant difference between LGSP-treated samples and control sample for sensory evaluation.
Conclusion:
Thus, LGSP is effective in reducing the level of acrylamide and maintaining the reasonable sensory attributes of potato fried foods. The results indicate that LGSP may be used as a potential additive for reducing acrylamide formation in fried foods. © 2019 Society of Chemical Industry.
