Nonthermal Sterilization of Animal-based Foods by Intense Pulsed Light Treatment
이경미,신정규 한국축산식품학회 2024 한국축산식품학회지 Vol.44 No.2
The consumption of meat has been increasing, leading to a dynamic meat and meat processing industry. To maintain the quality and safety of meat products, various technologies have been explored, including intense pulsed light (IPL) technology. Several factors affect the inactivation of microorganisms by IPL treatment, including light intensity (fluence), treatment duration, pulse frequency, and the distance between the lamp and the samples. Meat products have been studied for IPL treatment, resulting in microbial reductions of approximately 0.4–2.4 Log. There are also impacts on color, sensory attributes, and physico-chemical quality, depending on treatment conditions. Processed meat products like sausages and ham have shown microbial reductions of around 0.1–4 Log with IPL treatment. IPL treatment has minimal impact on color and lipid oxidation in these products. Egg products and dairy items can also benefit from IPL treatment, achieving microbial reductions of around 1–7.8 Log. The effect on product quality varies depending on the treatment conditions. IPL technology has shown promise in enhancing the safety and quality of various food products, including meat, processed meat, egg products, and dairy items. However, the research results on animal-based food are not diverse and fragmentary, this study discusses the future research direction and industrial application through a review of these researches.

The purpose of this study is contemplating the costume of the diplomats between the port-opening and the establishment of the Korean Empire. Western costume system included wearing daeryebok(大禮服;court-costume) when delivering credentials to rulers with soryebok(小禮服;formal dress) in other banquets. Not having its proper costume with diplomatic manner after the port-opening, Joseon gradually reformed its system. The costume of the diplomats at this time can be summarized as follows. The first stage was the period before the Gabshin-reformation甲申衣制改革 of 1884. The mission to Japan wore hongdanryung(紅團領) at audiences with rulers with pyeonbok(便服) in daily lives, while the Corean embassy to America seemed to wear plum-colored. The second one was the period after the Gabshin-reformation, when the diplomats wore heukdanryung(黑團領) as public, and chaksueui(窄袖衣) with jeonbok(戰服) as private. The last stage refers to the period after the Gaboh-reformation甲午衣制改革 of 1894 followed by the Eulmi-reformation乙未衣制改革 of 1895. The diplomats wore wide- sleeve heukdanryung with samo(紗帽) as daeryebok, narrow-sleeve heukdanryung with samo as soryebok, and chaksueui with jeonbok as tongsangbok(通常服;business suit) with examples of Min, Young-Hwan閔泳煥 and Lee Bum-Jin李範晉. Joseon maintained traditional-style daeryebok system until the establishment of the Korean Empire before they arranged the western-style court costume in April 1900. This system can be evaluated in that Joseon reacted to the period characterized by western dominance, with traditional systems merged into modern forms.
