Some differences among samples corresponding to the different batches could be observed, especially in the 12–16-day period; however, a definite trend about the effect on the PV of the algal extract presence in the icing medium could not be concluded.
The hydroxyl radical scavenging activity decreased to its lowest point after the withering and rolling process; then, it showed a clear trend of increasing and then decreasing with the start of fermentation, reaching a maximum of 20.68 mg Vc/g at the 12 h mark.
In contrast, the percentage of Na 2 SeO 4 remaining in the solution first showed a decreasing and then an increasing trend, with the increasing Na 2 SeO 4 concentration reaching the lowest value of 14.62 ± 0.99%, and the highest value of 70.32 ± 1.58% at the concentrations of the 0.5 mg/L and 10 mg/L Na 2 SeO 4 concentrations, respectively. 3.3.
pyrenoidosa showed a trend of first increasing and then decreasing with the increasing Na 2 SeO 4 addition concentration, reaching the highest value of 45.03 ± 0.07% and the lowest value of 19.75 ± 2.71% at 3 mg/L and 0.2 mg/L Na 2 SeO 4 concentrations, respectively.
At a processing time of 5 s, the moisture content of the rice treated with superheated steam showed a trend of first increasing and then decreasing, reaching its highest point at 170 °C.
With the delay in kernel development, carotenoid content of waxy maize showed a trend of first increasing and then decreasing, and reached the highest in S2.
The levels of ethers showed an overall increased trend, and the contents of ethers increased sharply in the 20th year of storage, with a maximum of 11.57%, and the contents of alkanes and acids showed a decreasing trend overall. 3.3.
Correspondingly, the growth rates of both fungi displayed a decreasing trend with 0.75–1.25% of CO concentrations, but this trend was reversed at higher CO levels.
Specifically, the inhibitory efficacy of the CO–C:G film against RM01 exhibited an increasing trend, ranging from 0 to 66% with a reduction in the fungal growth rate from 18.75 ± 0.00 cm 3 /day to 8.17 ± 0.05 cm 3 /day as the CO concentration increased from 0.75–5.0%.
While the lower dose (20 μg/mL) did not reach statistical significance, a decreasing trend in DNMT1 expression was observed compared to the H 2 O 2 and vehicle-treated group.
With the extension of the fermentation time, within the range of 0–10 d, the amount of CheA biosynthesis by each strain also showed an increasing trend.
Similarly, the MDA content showed a trend of first increasing and then decreasing ( Figure 4 b), and the nisin treatment could significantly reduce the MDA content of the fresh-cut pumpkins, indicating that nisin treatment could inhibit the occurrence of membrane lipid peroxidation.
Additionally, an increasing trend in AV, POV, and TBARS contents was observed after the freezing process, with lipid oxidation being significantly higher in the −18 °C group compared to the −25 °C group ( p < 0.05).
From 2012 to 2022, grain production in Qinghai showed a trend of first increasing and then decreasing, increasing from 109.44 × 10 4 t in 2012 to 188.47 × 10 4 t in 2017 and then decreasing to 107.27 × 10 4 t in 2022.
The results showed that grain production showed an increasing trend during the first half of this study period rather than the assumed continuous decline during this study period.
