Evidence Details
After being soaked in water for 4 h at various liquid-to-solid ratios (20: 1 – 60: 1 mL/g), the mixture suspension was placed in a XH-2008D ultrasonic extractor (Xianghu Technology, Beijing, China) and extracted at different powers (200 – 600 W) and temperatures (30 – 70℃) for 10 – 50 min.
According to response surface methodology, the optimal UAE for PKFs were liquid-to-solid ratio of 59: 1 mL/g, ultrasonic power of 404 W, time of 48 min, and temperature of 66℃, under which the yield of PKFs reached 26.8 ± 1.76 %, 2.6-folds higher than hot-water extraction.
At 1 mg/L, the hydroxyl radical-scavenging rate reached 92.9 ± 2.14 % ... The scavenging rate maximized at 0.8 mg/mL was 85.8 ± 1.65 %, slightly lower than that of LAA (88.2 ± 1.81 %), but remarkable difference was not observed.
The moisture-preserving rate of PKFs at 48 h was 95.6 ± 0.69 %, which was significantly higher than those of chitosan (92.1 ± 1.16 %) and glycerol (87.4 ± 1.04 %).
The PKFs yield with HWE was 10.4 ± 1.41 %, markedly lower (P < 0.01) than that of UAE (26.8 ± 1.76 %).
Yield evidence: source values include 26.8 ± 1.76%, 2.6 fold.
