摘要

本研究的目的是评价用紫蓝光处理后冷却储存的水煮沙丁鱼对水煮幼鱼的细菌去污效果。四种紫蓝发光二极管(led)照射后,测定样品的活细胞计数;峰值波长为405、412、421或455nm),随后冷却储存两天。LED (405 nm)具有杀菌和抑制生长的作用。与未辐照样品(对照组)相比,辐照灭菌率为47%,两天的储存抑制了细胞计数的增长至24%,而对照组的增长率为545%。对4株水煮沙丁鱼进行405 nm光照射后的综合生存力(IV)进行了生长延迟分析。辐照导致所有分离株的生长延迟,导致三株分离株的IV值低于根据菌落形成单位估计的存活率。在432 J/cm2的影响下暴露(405 nm)导致水含量减少,导致样品的盐度增加。本研究证明了光发射窄紫色区域作为一种非热消毒技术在煮沙丁鱼加工和储存中的优势。

Effects of Violet-Blue Light-Emitting Diode on Controlling Bacterial Contamination in Boiled Young Sardine.

The aim of this study was to evaluate bacterial decontamination of boiled young sardine by treatment with violet-blue light followed by cooling storage of the irradiated boiled sardine. Viable cell count in the samples was evaluated after irradiation with four types of violet-blue light-emitting diodes (LEDs; peak wavelength at 405, 412, 421 or 455 nm) and subsequent cooling storage for two days. LED (405 nm) exhibited bactericidal and growth suppression effects. The irradiation gave a 47% bactericidal rate in comparison with no irradiation samples (control) and the two-day storage suppressed the increase in cell counts to 24%, while the rate of increase was 545% for the control. Integrated viability (IV) based on growth delay analysis was estimated after irradiation of four isolates from boiled sardine with 405 nm light. The irradiation caused growth delay against all isolates, resulting in smaller IV values for three isolates compared to those viabilities estimated from colony forming units. Exposure (405 nm) at 432 J/cm2 fluence resulted in a decrease in water content, resulting in an increase in salinity of the samples. This study demonstrated the advantages of light emitting a narrow violet region as a non-thermal disinfection technology in the processing and storage of boiled sardines.
