  • This study analyzed the changes in the nutritional components, properties, physicochemical properties, general bacteria, and lactic acid bacteria of pickled cabbage depending on the cultivation area. An analysis of the nutritional composition on the first day of storage showed no significant difference in the calories, carbohydrates, protein, fat, and dietary fiber contents regardless of the cultivation region, but regional differences were observed in the vitamin C content in the order of Andong > Pyeongchang > Haenam. The total free amino acid content appeared in the order Andong > Pyeongchang > Haenam, and the GABA (γ-amino-n-butyric acid) content appeared in the order Haenam > Andong > Pyeongchang. In addition, pickled cabbage was observed on the 1st, 5th, and 10th days of storage at 4℃. No significant change in appearance was observed on the 1st and 5th days, but changes were observed on the 10th day. Regardless of the cultivation area, the salinity (p<0.05) and pH (p<0.05) decreased significantly as the storage period increased, while the sugar content (p<0.05) and acidity (p<0.05) increased significantly. The general bacteria (p<0.05) and lactic acid bacteria (p<0.05) counts increased significantly as the storage period increased, irrespective of the cultivation region.

  • Response surface methodology (RSM) was used for the optimization of antioxidant capacity in gardenia extracts. The antioxidant capacities of gardenia fruit extracts were investigated by ferric reducing ability (FRA) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity (RSA) assays. The optimum extraction parameters for the strongest antioxidant capacity were the ethanol concentration (EtOH) of 48.9%, extraction temperature of $72.9^{\circ}C$, and extraction time of 29.9 min. Analysis of variance (ANOVA) showed that the quadratics of EtOH and extraction temperature had highly significant effect on the antioxidant capacity (p<0.001). The antioxidant capacity was correlated with contents of bioactive components [crocin, geniposide, and total phenolic (TP) compounds] in gardenia extracts and mainly attributed to the content of the TP compounds.

  • Farmers need timely information on the nutritional status of their animals and the nutritive value of pastures and supplementary feeds if they are to apply successfully this existing nutritional information. Near infrared reflectance(NIR) spectroscopy has been used over the last forty years to analyse accurately protein, fiber, and other organic components in animal foods. NIR spectroscopy is a rapid, non-destructive, and non-polluting technology. When properly calibrated, NIR spectroscopy is used successfully with both concentrate and forage feeds. NIR methods predict in vitro digestibility accurately and precisely, and can predict in vivo digestibility at least as well as conventional "wet chemistry" methods such as in vivo digestion or the pepsin-cellulase method, and much more rapidly. NIR technology has been applied to the routine monitoring (through analysis of feces samples) of the nutritional status of cattle and other grazing animals. This report reviews the use of near infrared reflectance(NIR) spectroscopy to monitor the nutritive value of animal feeds and the nutritional status of grazing animals.

  • Purpose: This study aimed to identify the factors influencing quality of life (QoL) of low-income older adults (LOAs) with sarcopenia. Methods: A convenience sample of 125 older adults was recruited from Jeonbuk Province, South Korea. Data were collected using a self-report questionnaire that included nutritional status, the Depression Anxiety Stress Scale-21, and the World Health Organization Quality of Life Instrument-Older Adults Module. Additionally, grip strength and appendicular skeletal muscle mass, were evaluated, along with the short physical performance battery. Results: Sarcopenia and severe sarcopenia were observed in 43.2% and 56.8% of participants, respectively. Using multiple regression analysis, depression (β = - .40, p < .001), nutritional status (β = .24, p = .003), and anxiety (β = - .15, p = .042) were identified as factors affecting the QoL of the older adults in low-income groups with sarcopenia, the explanatory power of these variables was 44%. Conclusion: The results of this study can be used to develop a nursing intervention program and establish policies to improve depression, anxiety, and nutritional status to enhance QoL of LOAs with sarcopenia.

  • The objective of this study was to investigate the effect of sample presenting types on the sensory characteristics of chilled buckwheat noodle soup (Naeng-myeon). Generic descriptive analysis was performed for evaluating only stock (system 1), only noodle (system 2) and stock with noodle (system 3). Eight kinds of commercially available Naeng-myeon were samples of interest. Ten female descriptive panelists participated. ANOVA and regression analysis were used for data analysis. In the training sessions, ten sensory properties were developed for system 1, four were additionally established for noodle. In each system, the 8 products showed significantly different intensities in almost all sensory attributes like darkness of stock, overall flavor, sweetness, saltiness, sourness. When integrating the two systems, sample presenting types showed significant difference for the seven sensory attributes, especially saltiness, sourness, beef flavor tended to be rated more strongly in system 1 than system 3.

  • Purpose: This study aims to analyze the importance of customers' selection attributes for meal kits, which is rapidly increasing in the home meal replacement food market, and empirically analyze the effect of food selection attributes on consumer satisfaction and repurchase intention toward meal kits. Research design, data, and methodology: Based on the results of previous research, factors that customers consider the most when purchasing a meal kit are nutritional components, ingredients, hygiene, taste, and price. The empirical analysis is conducted by using structural equation modeling to determine the extent that customer selection attributes for meal kits affect customer satisfaction and repurchase intention. The survey is conducted online from January 1 to March 15, 2022, and 282 valid samples are used for the analysis. Results: The result of the analysis confirms that nutritional components, hygiene, taste, and price have a statistically significant effect on customer satisfaction and repurchase intention. However, the effect of food ingredients on customer satisfaction and repurchase intention is rejected because no statistically significant results are obtained. Conclusions: As an empirical analysis of the importance of customer selection attributes of meal kits, this study has meaningful implications for related industries and business-to-business operators and provides basic data for the strategic development of related industries.

  • In this study, Artemisia capillaris, which has been used in oriental medicine and folks remedy, was investigated to characterize the nutritional composition (protein, lipid, ash, fiber, amino acids, fatty acids, Na, K, P, Mg, Ca and Fe) and effective substance (scopoletin). Artemisia capillaris has often been cited in medical literature for its medicinal effects. The Korean Food and Drug Administration allowed Artemisia capillaris as a food stuff and indicated as In-Jin-Sook. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. Therefore, we need to develop functional foods using In-Jin-Sook. Artemisia capillaris was superior in protein, crude fiber, amino acid and fatty acid compositions to wild greens according to Korean Nutritional Composition Table. Also scopoletin, blown for blood vessel relaxation and hypotensive effect, was detected at the level of 326.13 $\mu\textrm{g}$/g. These results demonstrated that Artemisia capillaris has both pharmaceutical effects and balanced nutritional contents. Artemisia capillaris has sufficient values to use as a food stuff for functional foods.

  • We investigated the effect of paternal folate status on folate content and expression of the folate transporter folate receptor ${\alpha}$ ($FR{\alpha}$) in rat placental tissues. Rats were mated after males were fed a diet containing 0 mg of folic acid/kg of diet (paternal folate-deficient, PD) or 8 mg folic acid/kg of diet (paternal folate-supplemented, PS) for 4 weeks. At 20 days of gestation, the litter size, placental weight, and fetal weight were measured, and placental folate content (n=8/group) and expression of $FR{\alpha}$ (n=10/group) were analyzed by microbiological assay and Western blot analysis, respectively. Although there was no difference observed in litter size or fetal weight, but significant reduction (10%) in the weight of the placenta was observed in the PD group compared to that in the PS group. In the PD group, placental folate content was significantly lower (by 35%), whereas $FR{\alpha}$ expression was higher (by 130%) compared to the PS group. Our results suggest that paternal folate status plays a critical role in regulating placental folate metabolism and transport.

  • This study was conducted to investigate housewives' perception, interest and consumption of health drinks made in a health food stores, and to assess the relationsh- ip between nutritionally-related-variables and the consumption of health drinks. Data was collected from 518 housewives in Chonnam province. Among many items which housewives perceived about health drinks, three factors of 'preference·health-care', ' quality·convenience' and 'price' were found to be represented. Housewives' perception of 'preference·health-care' was negatively correlated with nutritional knowledge. However, a positive correlation between the 'quality·convenience' and eating habits was found. Consumption of health drinks was positively correlated with the diet management score, the perception and interest in health drinks. However, the inverse relationship between consumption of health drinks and nutritional knowledge was observed. Multiple regression analysis showed that the interest and factors of perception of health drinks. Consumption of health drinks was not based upon accurate knowledge concerning nutrition, but was based upon the consumers' perception of taste preference and healthful quality. Therefore, there is a need to educate consumers about the nutritional value of health drinks and how to use nutritional supplements.

  • This study was performed to investigate nutritional intakes and preference food and blood composition of female college students of premenstrual syndrome. Based on physical measurement test results, both groups showed no noticeable difference and both groups were within the normal range according to body composition analysis. In terms of nutrients consumption, results showed nutritional intakes more than EAR(estimated average requirements) included phosphorus>vitamin $B_6$>vitamin $B_1$, while nutritional intakes less than EAR were vitamin A>vitamin $B_6$>calcium>folic acid. A significant difference was observed for vitamin C intake(p<0.05). The overall mean values of basic blood(WBC, RBC, Hct, and Hb), sex hormone(Estrogen, Progesterone), aldosterone, cortisol, Cu, Zn, and Ca, Mg indices in female college students were within the normal range and there was no significant difference between the PMS group and the Normal group. In conclusion, vitamin C intake of the PMS group showed a level of 84.8% EAR. Therefore vitamin C supplement can be beneficial to relieve the PMS Syndrome.
