Abstract

This study investigated the effects of ultrasonic treatment combined with slightly acidic electrolyzed water (SAEW) on peanut seed germination, focusing on germination percentage, microstructure, microbial loads, and microbial diversity. The results demonstrated that the combination of ultrasound and 70 ppm SAEW synergistically enhanced peanut germination, achieving an impressive germination rate of 90 %. Compared to the control group, the treatment involving ultrasound in conjunction with SAEW resulted in a reduction of total microbial counts by 7.84 and 5.52 log₁₀ CFU/g on days 1 and 2, respectively. Furthermore, mold and yeast growth were significantly inhibited due to the synergistic action between SAEW and ultrasound. The cavitation bubbles generated by ultrasound likely facilitated the penetration of SAEW into cells, thereby enhancing its effectiveness in increasing cell membrane permeability. This study provides valuable insights into a sustainable and effective approach for improving peanut germination while simultaneously controlling microbial contamination.

超声波和微酸性电解水处理对花生种子的协同促萌发和抑菌作用

研究了超声处理与微酸性电解水（SAEW）联合处理对花生种子萌发的影响，重点研究了发芽率、微观结构、微生物负荷和微生物多样性。结果表明，超声与70 ppm的SAEW组合可协同提高花生的发芽率，达到90%。与对照组相比，超声联合SAEW治疗在第1天和第2天分别使总微生物计数减少7.84和5.52 log10 CFU/g。此外，由于超声和SAEW的协同作用，霉菌和酵母的生长受到显著抑制。超声产生的空化泡可能促进了SAEW进入细胞，从而增强了其增加细胞膜通透性的有效性。该研究为促进花生发芽同时控制微生物污染的可持续有效途径提供了有价值的见解。

期刊介绍： LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
