SUBJECTS/METHODS The data from 513 elderly individuals aged 65 or older were analyzed using the raw data from the Seoul Food Survey 2023. The subjects were classified […]

Synergistic effect of naringenin and mild heat for inactivation of E. coli O157: H7, S. Typhimurium, L. monocytogenes, and S. aureus in peptone water and cold brew coffee

This study aimed to investigate the bactericidal effect of naringenin (NG), a plant-derived flavonoid, and its synergistic effect with mild heat (MH) treatment at 50 °C in peptone water (PW) and ready-to-drink cold brew coffee (RDC). Among various NG concentrations (1–20 mM), 10 mM NG resulted in the greatest inactivation for Escherichia coli O157:H7, Salmonella Typhimurium, Listeria monocytogenes, and Staphylococcus aureus. In RDC, NG + MH […]

Synergistic antibacterial effect of 405 nm blue light-emitting diodes (LEDs) and gelatin film for inactivation of Escherichia coli O157:H7 and Salmonella Typhimurium on stainless steel and fresh fruit peel

A combined antibacterial effect of 405 nm blue LEDs (BL) and gelatin film (G) was investigated on stainless steel (SUS) and fresh fruit peel for the inactivation of Escherichia coli O157:H7 and Salmonella Typhimurium. On the SUS, the sum of the individual treatments of G for 20 min and BL at 20 J/cm2 was <1 log reduction (log CFU/cm2). In comparison, combination […]

Bioconversion of cabbage juice: Enhanced S-Methylmethionine via non-thermal treatment and lactic acid bacteria fermentation

Bioconversion technology represents a promising strategy for enhancing the functional attributes of natural products, with significant implications for the food industry. This study focused on the application of bioconversion technology to cabbage juice, a cruciferous vegetable renowned for its nutritional value and health-promoting properties. To facilitate effective fermentation, non-thermal treatments, including ultrasound, UV-lamp, and aeration tank, were […]

북한 주민의 영양실태 및 남한 성인의 북한 주민의 영양실태 관련 인식

Objectives North Koreans have been facing chronic food shortages and malnutrition. This study examined the nutritional status of North Koreans and the perceptions of South Korean adults regarding their nutritional status. Methods The nutritional status was examined using nutritional indicators for the general population, children, and reproductive-aged women in North Korea. An online survey was conducted among […]

영·유아 어머니의 이유식 지식수준 및 간편이유식에 대한 인식

Objectives The purpose of this study was to examine mothers’ knowledge levels on complementary foods and their perception of convenience complementary foods. Methods An online survey was conducted with mothers aged 20–49 years who had purchased convenience complementary foods and had a preschool child aged 4 months or older. The respondents were categorized into 3 groups based […]

Synergistic antimicrobial effects of ammonium persulfate, ultrasound, and mild heat on Staphylococcus aureus under varied conditions

This study elucidated the antimicrobial effect of ammonium persulfate (PS), ultrasound (US), and 40–60 °C mild heat on Staphylococcus aureus ATCC 27213 under various growth conditions, including non-adaptation, pH-adaptation, and aridity-adaptation, in buffered peptone water (BPW) and on orange peel surfaces. For non-adapted, pH-adapted, and aridity-adapted S. aureus, the combined treatment of PS, US, and mild heat showed a synergistic effect, with log reductions of 2.05, […]

Synergistic antimicrobial action of chlorogenic acid and ultraviolet-A (365 nm) irradiation; mechanisms and effects on DNA integrity

Chlorogenic acid(CGA) is abundant in various plants and notably in coffee beans. This study investigated the bactericidal activity of CGA combined with ultraviolet-A light (UVA, 365 nm) (CGA + UVA) against Escherichia coli DH5α, with the aim of developing novel strategies for food preservation and healthcare. CGA + UVA treatment was superiorin reducing bacterial survival than either treatment alone. At […]
