1. In Section 6.3, you state that a 180 s plasma treatment diminished around 90% of PPO activity, while a 240 s treatment only inactivated 85% of PPO activity. This is mathematically and logically inconsistent, longer exposure cannot yield lower inactivation unless there is a clear mechanistic explanation (e.g., enzyme reactivation or measurement artifact). Please clarify this discrepancy and provide raw data or statistical validation for these values.

2. In Table 1, you cite Lee et al. [95] for Escherichia coli inactivation on almonds using dielectric discharge for 30 s achieving a 1.8–5 log reduction. However, the cited reference [95] (Lee et al., International Journal of Food Microbiology, 2023) actually investigates in-package cold plasma treatment on steamed rice cakes, not almonds. This appears to be a citation error. Please verify and correct all citations in Table 1, as such inaccuracies undermine the credibility of the review.
