Suspensions of Lactobacillus plantarum cells were subjected to either conventional heating, continuous microwave (CW) or pulsed microwave (PW) irradiation at 50°C for 30 min. Samples exposed to PW showed greater reductions (2 ∼ 4 log) in survival counts than those treated with either conventional heating or CW irradiation. As exposure time increased, PW resulted in a remarkable increase in 260 nm‐absorbing compounds that leaked into the suspending menstruum, as compared to CW or conventional heating, indicating that PW irradiated cells were the most injured. The growth of PW irradiated cells was delayed about 24h and the final acidity of the culture broth was about 60 ∼ 80% that of other cells treated with conventional heating or CW irradiation.

To investigate the preference of food of the elderly for developing processed elderly food, this study was conducted from February 2014 to March 2014 by questionnaire including dietary behaviors, food preference, and frequency of food intake to 119 elderly (49 males and 70 female) who were more than 65 years old and living in Jeonju. Most subjects ate three meals regularly and most of the subjects’ favorite meal time was lunch. The duration time of one meal was 20 min (48.74%). The most preferred taste was delicate and sweet. The subject preferred cooked rice with multi-grains, kalguksu (hot noodle), and abalone porridge to other staple foods. Almost 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 72.3%. Preference for panfried foods leaned toward pan fried fish fillet and mung bean pancake. Most subjects preferred plant foods like vegetables, lettuce, and seaweeds. The elderly in Jeonju liked roasted pork, grilled yellow croaker, and stir-fried octopus. Cooked and seasoned vegetables (namul) were the most preferred type by the elderly. Preferences for dishes and food materials were not affected by sex and ages. Most subjects preferred eating out with Korean food. Preference for eating food was selected in grilled beef ribs, a pork cutlet, sushi·broiled eels, and Chinese noodles. Western Japanese and Chinese food were preferred by an elderly subject, who was male and who liked Japanese food more than female.

The overconsumption of dietary salt is recognized to play a negative effect on human health such as increasing blood pressure. The purpose of this study is to investigate the effect of hydrolyzed anchovy products (HAP) on the salty taste of dried noodle. The physicochemical properties and sensory test of dried noodle were determined at different concentrations of HAP. The lightness of the noodle samples was decreased with increasing levels of HAP whereas their redness and yellowness were increased. There were no significant changes in hardness and texture properties by HAP concentration, compared to those of the control. From the sensory evaluation, the 25% and 50% HAP samples showed a high score on saltiness, preferredness, and overall taste acceptability. Consequently, the HAP could be utilized in dried noodles or cooked noodles as a salt enhancer without significantly altering the charateristics of noodles.

Application of intense pulsed light (IPL) treatment is an emerging technology with interesting prospects in food preservation. However, information concerning the factors affecting the inactivation of microorganisms and their impact on the quality of fresh-cut food is scarce. In this study, the effects of IPL treatment on the microbial inactivation and physicochemical change in paprika were determined. The viability of bacteria in paprika treated with IPL decreased slightly with the treatment time. In addition, water content was slightly decreased after IPL treatment regardless of the color of paprika. However, except in red paprika, sugar content increased after IPL treatment. The pH of paprika increased in all samples, and the polyphenol content decreased with treatment time, but these differences were very small. After IPL treatment of paprika, vitamin C content increased in yellow and red samples. Hunter color values-lightness (L), redness (a), and yellowness (b)-increased in red paprika, but all values decreased in orange paprika.

The draft genome sequence of Halorubrum sp. SAH-A6, isolated from commercial rock salts of the Danakil depression, Ethiopia. The genome comprised 3,325,770 bp, with the G + C content of 68.0%. The strain has many genes which are responsible for secondary metabolites biosynthesis, transport and catabolism as compared to other Halorubrum archaea members. Abundant genes responsible for numerous transport systems, solute accumulation, and aromatic/sulfur decomposition were detected. The first genomic analysis encourages further research on comparative genomics, and biotechnological applications. The NCBI accession number for this genome is SAMN04278861 and ID: 4278861 and strain deposited with accession number KCTC 43215.
