Abstract

Allium chinense G. Don waste (ACGD) has an abundance of polysaccharides (ACGDP). Therefore, in this study, a method for extraction of ACGDP from ACGD by ultrasonic-assisted hot water extraction (UAE) based on ultrasonic cleaning equipment was developed. It was compared with hot water extraction (HWE) in terms of efficiency, energy consumption, and carbon emissions. Then, the mechanism of efficient extraction of ACGDP by UAE was further investigated. Finally, the physicochemical properties and in vitro activity of ACGDP were evaluated. The results suggested that the optimal conditions of UAE were temperature 53 ℃, time 34 min, power 280 W, liquid-solid ratio 22 mL/g, and the yield of ACGDP was 30.08 ± 0.21 %. Compared with HWE, UAE yield was increased by 30.10 %, time was shortened by 71.50 %, energy consumption was reduced by 77.33 %, and CO₂ emission was reduced by 82.56 %. UAE can efficiently extract ACGDP by changing the composition of the cell wall, destroying the microstructure, and reducing the particle size. In addition, ACGDP had better thermal stability and antioxidant activity, and exhibited positive hypoglycemic activity. Overall, this study provided a theoretical basis and new insights into the efficient extraction mechanism of UAE and the high-value utilization of ACGD waste.

超声辅助提取葱表皮废多糖：提取机理、理化性质及生物活性评价。

Allium chinense G. Don waste （ACGD）含有丰富的多糖（ACGDP）。因此，本研究开发了一种基于超声清洗设备的超声辅助热水萃取法（UAE）从ACGD中提取ACGDP的方法。在效率、能源消耗和碳排放方面，将其与热水提取（HWE）进行了比较。在此基础上，进一步探讨了UAE高效提取ACGDP的机理。最后，对ACGDP的理化性质和体外活性进行了评价。结果表明，最佳工艺条件为温度53℃，时间34 min，功率280 W，液料比22 mL/g， ACGDP得率为30.08±0.21%。与HWE相比，UAE产率提高30.10%，时间缩短71.50%，能耗降低77.33%，CO2排放量降低82.56%。UAE可以通过改变细胞壁组成、破坏微观结构、减小粒径等方式有效提取ACGDP。此外，ACGDP具有较好的热稳定性和抗氧化活性，并表现出良好的降血糖活性。综上所述，本研究为探究UAE的高效提取机理和ACGD废弃物的高价值利用提供了理论依据和新的见解。
