This study was done to analyze the consumption patterns of health functional food (HFF) as well as to perform needs assessment for the development of web-contents on HFF according to age of adults. The subjects were 238 male and female adults, divided into 4 groups by their age. This study collected all information by self-administrated questionnaires. The awareness on HFF was high in the older adults. The younger adults showed more negative responses to reliability and safety on HFF. The main reason for the consumption of HFF was to supplement nutrients and to prevent diseases. The main types of HFF consumed by adults were nutritional supplementary food, red ginseng products, and glucosamine products. There was higher consumption of nutritional supplementary food in the younger adults and glucosamine products in the older adults. Internet users had low level of satisfaction, with tendency to complain poor contents, reliability, difficulties in searching as problems of the pre-existing HFF websites. As useful methods for provision of information on HFF, most adults wanted general information, articles written by experts and videos. They also wanted to know the safety and side effects of HFF. Requirement of contents composition were various in-depth information, clear indication of citation, fresh updated data while that of display composition was easily-findable, uncomplicated, allowing mutual exchange of communication through bulletin board. These results can be used as basic data that reflect the consumer's needs for developing HFF web-contents according to age of adults.

The purpose of this study is to explains consumers' medical discourse embedded in the consumption of oriental medicine and health functional foods. Despite the fact that both of oriental medicine and western medicine is legally accepted, people tend to recognize that accurate diagnosis is possible only in the latter. As the discourse that oriental medicine, compared with western medicine, has an auxiliary position is widely spreaded, the rivalry between herbal medicine and health functional foods come to be formed. And it led to a close correlation between the decrease of herbal medicine consumption and the growth of health supplement market. Herbal medicine is compared to red ginseng, one of the representative health supplement. Negative notion such as using an Asian herb from China and side effect of hepatotoxicity influences herbal medicine consumption. This study argues two conclusion. First, the correlation between the consumption of herbal medicine and that of health functional foods results from the discourse of scientific reconstruction, standardization, and commercialization all of which come from globalization discourse. Second, medical discourse embedded in these commodity, in the end, has impact on agricultural production.
BACKGROUND/OBJECTIVES: The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. SUBJECTS/METHODS: We conducted online surveys of 400 Chinese international students and 452 Korean college students from January to February 2021. We analyzed the factors related to the use of dietary supplements by these students using multi-group structural equation modeling and logistic regression analysis. RESULTS: Approximately 65% of the Chinese international students and 93% of the Korean college students consumed dietary supplements at least once in the year preceding the survey. The common types of dietary supplements consumed by both groups of students were vitamin and mineral supplements, Lactobacillus products, and red ginseng products. Structural equation modeling showed that perception of the consumption of dietary supplements by family and friends positively influenced attitude toward dietary supplements. This effect was higher for Korean college students than for Chinese international students (P < 0.01). Attitude toward dietary supplements positively influenced their use, and this effect was higher for Chinese international students than for Korean college students (P < 0.001). Logistic regression analysis showed that the use of dietary supplements by Chinese international students was significantly associated with age, self-reported health status, interest in health, perception of and attitude toward dietary supplements, and length of residence in South Korea. Among Korean college students, it was associated with exercise frequency and attitude toward dietary supplements. CONCLUSION: This study showed significant differences in the use of dietary supplements and related factors between Chinese international and Korean college students. Therefore, nutrition education programs on dietary supplements need to have differentiated content for each group. Such differences also suggest that the industry should consider the relevant characteristics of college students while developing and marketing dietary supplements.
In the present study, we investigated the biological activities of Xylosma congesta leaf ethanol extract (XCO) using a variety of in vitro and cell culture model systems for anti-melanogenic, anti-wrinkle, anti-inflammatory and anti-oxidant activities. First, XCO markedly inhibited ${\alpha}$-melanocyte stimulating hormone-stimulated melanin synthesis in B16F10 cells. Secondly, XCO marginally induced procollagen synthesis in CCD-986SK cells. Thirdly, XCO dose-dependently suppressed lipopolysaccharide-induced nitric oxide (NO) production in RAW 264.7 cells. XCO did not affect cell viability at different concentrations used in this study, indicating that XCO-mediated inhibition of melanin, procollagen and NO synthesis is not mediated by cytotoxicity. Finally, XCO was found to exert anti-oxidant effect. Taken together, these findings demonstrate for the first time that XCO possesses anti-melanogenic, anti-wrinkle, anti-inflammatory and anti-oxidant activities, and suggest further evaluation and development of XCO as a functional supplement or cosmetic that may be useful for whitening skin, reducing wrinkles and treating inflammatory responses.
The present study was conducted to investigate the effects of dietary supplementation of fermented wild-ginseng culture by-product on egg production, egg quality and blood characteristics in laying hens. A total of 216 ISA Brown laying hens, 55 wk of age, were used in the 6-wk feeding trial. Experimental diets were consisted of basal diet (CON), 2.5% fermented wild-ginseng culture by-product replaced lupin in basal diet (WG1) and 5.0% fermented wild-ginseng culture by-product replaced lupin in basal diet (WG2). Birds were randomly allotted to 18 replicate pens. There were 6 replicates per treatment, and 12 laying hens per replicate. Through the 6-wk feeding trial, egg production was significantly increased in WG1 and WG2 treatments compared to CON (P<0.05). Egg weight was significantly higher in WG2 than CON (P<0.05). WG1 resulted higher yolk color than CON (P<0.05). Albumen height and Haugh unit were significantly improve in WG1 compared to WG2 (P<0.05). Red blood cell was significantly lower in WG2 than CON (P<0.05). LDL-cholesterol was significantly decreased in CON compared to WG2 (P<0.05). In conclusion, fermented wild-ginseng culture by-product could improve egg production and egg weight in laying hens.

In order to improve the storage stability of spray and freeze dried red ginseng extract powder packed in a bottle, the water vapor permeability of Al-foil laminate paper used for cap closure and shelf life of those products on various storage temperatures and relative humidities were investigated. The thickness of the laminate paper was $93{\pm}3\:{\mu}m$ and its physical properties were equal to standard of ASTM (B-377-66) The absorption rate of the freeze dried powder was 2-6 times greater than that of the spray dried powder at $37^{\circ}C$. Therefore it was considered that the laminate could be used for cap closures for the spray dried powder but unsuitable for the freeze dried powder. The shelf life of the spray dried powder was longer than that of the freeze-dried powder at $37^{\circ}C$.

In order to improve the physical properties on moisture sorption of spray dried red ginseng extract powder (SD-RGEP), the various additives and coating agents were treated, and solubility, sedimentation rate and storage stability of RGEPs treated were investigated. For the moisture-proofing, additive itself was effective in the order casein>dextrin>starch>avicell, but RGEPs treated with additives were effective in the order cord oil+tween-40>starch>casein. But there was no significant difference between RGEP treated less than 1% additive and the moisture-proofing. The coating effect of AEA and CAP on RGEP could not be recognized for the moisture-proofing, whereas that of HPC, corn oil, lecithin and HPC+corn oil was proved to be very effective for the moisture-proofing of RGEP. Also it is required to control the initial moisture content of RGEP. The sedimentation rate of RGEP nontreated was 65.1 seconds, whereas that of RGEPs coated with 1% HPC, 1% corn oil, 1% lecithin and 1% HPC+0.5% corn oil was in the range of 96.2 to 114.3 seconds. The sedimentation rate of RGEPs coated was 1.5 to 1.8 times higher than that of RGEP nontreated, and there was significant difference between solubility and sedimentation rate. Therefore it was no matter for the keeping quality. The sorption rates of RGEPs coated with lecithin $(0.5{\sim}1.0%$), corn oil(0.8%) and cellulose acetate (0.8%) were ranged 54 to 56%, 51 to 55% and 52 to 54%, respectively, and it is found that the moisture-proofing effect of RGEPs coated was about 2 times higher than that of RGEP nontreated. From the result of storage experiment during 3 months under the maltreated condition of $48{\pm}2^{\circ}C$, 75% RH, the moisture sorption of RGEPs coated with corn oil$(0.5{\sim}1.0%$), cellulose acetate(DES, $0.5{\sim}0.8%$) and lecithin (DES, 1.0%) was not at all observed. Therefore it is considered that the circulating period of RGEPs coated with these coating agents could to give more than 3 years.
The application of color retention agents (3 items), preservatives (17 items), and bleaching agents (6 items) as food additives in processed foods were investigated by food type. Among color retention agents, sodium nitrite was used the most with 257 cases, mainly in seasoned jeoktal (71.21%), ready-to-eat foods (7.78%), and breads (4.87%). Of the benzoates (1,236 cases) used as a preservative, sodium benzoate showed up most, in 1,215 cases, while 81.16% of these were in beverages such as beverage base (39.51%), mixed beverages (22.47%), and ginseng/red ginseng beverages (8.89%). Grapefruit seed extracts (3,291 cases) were applied to 44 types of processed foods such as sauces (54.65%), liquid tea (10.46%), and other products (5.15%). Ethyl p-hydroxybenzoate (2,957 cases) was applied to products (total 96.44%) such as sauces (92.15%), blended soy sauce (2.77%), and pickled foods (1.52%). Potassium sorbate was applied to a total of 789 cases, mainly pickled foods (40.43%) and processed fishery products (47.15%). All 27 cases of sorbic acid were applied to fish paste (100%). Of the bleaching agents, sodium bisulfite and sodium hydrosulfite were mainly used in confectioneries, breads or rice cakes, and potassium metabisulfite, sodium metabisulfite, and sulfur dioxide were mainly found in alcoholic beverages including fruit wine, while sodium sulfite was mostly used in pickled foods. These results are deemed useful in applying food additives to processed foods.
This study will evaluate the effect of fermented Morinda citrifolia L. extracts and its marker compounds to provide baseline data for utilizing Morinda citrifolia L. as functional health products. Morinda citrifolia L. and six marker compounds were processed on RAW 246.7 macrophage to test for XTT Cytotoxicity, measure Nitric Oxide and Cyokine formation, and analyze the expression of immune marker genes. Furthermore, LPS and fermented red ginseng extract, a common functional ingredient, are used as positive controls. Our results showed that fermented Morinda citrifolia L and six bioactive compounds did not have any cytotoxic effect in all treatment concentrations and groups. Among six bioactive compounds, SCP and ASE confirmed the formation of NO. In addition, the ASE treatment group showed increased formation of IL-6 and IL-1β and the expression of iNOS and TNF-α. Also, fermented Morinda citrifolia L extract activated the macrophage by enhancing the production of nitric oxide (NO), interleukin (IL)-6, and IL-1β, and the expression of COX2 compared to Morinda citrifolia L. extracts. The result of the study showed that Fermented Morinda citrifolia L. (Noni) and marker compound enhance the innate immunity activity and suggested that the bioactive compound could be applied as a marker compound. Thus, Fermented Morinda citrifolia L. (Noni) could be used as functional food material to develop immunity-enhancing products, and highly functional marker compounds can be utilized as the effective components.

Objectives The purpose of this study is to see the prevalence and the patterns of the use of complementary and alternative medicine (CAM) in children and adolescent patients with allergies. Methods We analyzed data on 547 children and adolescents (age from 0-18 years old) chosen from all regions throughout the country with allergic diseases, including atopic dermatitis, allergic rhinitis, asthma and allergic urticaria. We used multiple logistic regression modeling to predict CAM use based on predictor variables. Results The previous 12-months prevalence of CAM usage in overall was 70.7% (atopic dermatitis, 78.1%; allergic rhinitis, 52.9%; asthma, 70.3%; allergic urticaria, 86.3%). Central and southern regions displayed significantly lower rate of using CAM compare to the northern region, and CAM was less likely to be used for the allergic rhinitis patients than the atopic dermatitis patients. The most commonly used CAM type was natural products (62.2%). Top five of the most frequently used CAM modalities were softener water, vitamin, red ginseng, wood bathing and aloe oil. One of the main reasons for trying CAM was from the 'hope for a more effective outcomes in additional to the conventional medicine' (43.9%). The subjective effectiveness of CAM was found to be excellent in 74.0% of the patients, and 70.3% of the parents were willing to recommend CAM therapies to the others. Conclusions CAM is used widely to treat allergic diseases in children and adolescents in Korea. Korean medical doctors should actively discuss the use of CAM with the patients and provide information on the effectiveness and safety of CAM as guide in making choice for usage of CAM.
