Abstract

Abstract The influence of microwave blanching (MWB) at different times (30–120 s) on the physicochemical properties, microstructure, and drying characteristics of apple slices, compared to steam blanching (SB) was investigated. Results showed that MWB resulted in greater weight loss and more efficient enzyme inactivation efficiency than SB. The MWB process facilitated the moisture diffusion, resulting in a significant ( p < 0.05) reduction in drying time of up to 27.78 % and specific energy consumption of up to 50.00 %. Microstructural observations confirmed that this result stemmed from the development of microporous channels within the cellular tissue structure. The Page model exhibited a higher applicability to the drying of apple slices. Moreover, MWB was more effective than SB in inhibiting browning and retaining phenolic compounds. However, concerning amino acid retention, the dried samples treated with SB for 30 s (21.36 ± 0.83 mg/g DW) showed superior performance compared to dried samples treated with MWB. In addition, molecular docking results suggested that amino acids could form the distinctive flavor of dried apple slices through hydrogen bonding with taste receptors.

8 of 13 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
