We investigated consumer perceptions of and purchase intentions for health foods. Data were collected from 454 adults over the age of 20 years living in Seoul and Gyeonggi province, from May 10 to June 5, 2010. Those that "hardly ever drink" (41.4%) were most prevalent in terms of drinking activity, whereas 80.8% of respondents did not smoke. Also, those who responded "hardly ever exercise" ranked highest; although 43.8% in fact exercised frequently. Of all respondents, 44.5% admitted to suffering slightly from stress. A total of 59.5% of respondents opined "I am healthy but I do worry about health", and "exercise" topped the list of approved (37.2% of respondents) health care methods. We also found that 83.5% of respondents claimed to have tried health foods, whereas in the case of having no taking experience, 60% had not purchased such foods because, in their view, this was unnecessary. The extent of concerns about health foods scored 3.09, and the level of purchase intentions for health food was high, with a score of 3.40. Therefore, all of government, producers, distributors, and academic researchers must provide consumers with accurate and complete information, and need to collaborate in the development of consumer education programs on health foods. This will enhance consumer interest in such foods, and empower logical choices.

The analytical method of silicon dioxide ($SiO_2$) in health functional food products was developed employing inductively coupled plasma optical emission spectrometry (ICP-OES) method assisted by acid (hydrofluoric acid and boric acid) digestion in open system without alkali fusion. The limit of detection (LOD) and limit of quantification (LOQ) of this method were found to be 0.07 and 0.20 mg/L, respectively. Linearity ($r^2$) and linear range were 0.99 and 0.20~20.0 mg/L, respectively. The accuracy and precision of $SiO_2$ (0.4, 1.0, and 2.0%, w/w) in spiked glucosamine exhibited to be the range of 90.22~94.14% and 0.72~1.67%, respectively. The contents of $SiO_2$ in 11 health functional food products were detected in range of 0.02~1.80% (w/w). Every sample showed below content of the permitted use level (2%, w/w) of $SiO_2$. Therefore ICP-OES method with acid can analyze the content of $SiO_2$ in health functional food products easily and rapidly. Consequently, the application of specification analysis of $SiO_2$ in health functional food products could be a significant work.

Human skin is continuously exposed to internal and external influences that may affect its condition and functioning. To maintain and improve skin condition, a wide variety of skin-care products is in the market. However, many of skin problems originate from internal causes, and the new insight into the relation between nutritional factors and skin is now receiving a great attention. Specific positive effects of nutrients or nutraceutical compounds on skin conditions may prove to be biologically relevant and may consequently allow for claims on products containing these compounds, resulting in the development of new functional food for optimal skin condition. In this review, these functions of nutrients and nutraceutical compounds in skin are summarized as providing a basis for the feasibility of the concept of functional foods for maintaining and improving skin condition.

A method based on high-performance liquid chromatography (HPLC) with ultraviolet detection has been developed to quantify coenzyme Q10 (CoQ10) in raw materials and dietary supplements. Single-laboratory validation has been performed on the method to determine linearity, selectivity, accuracy, limits of quantification (LOQ) and repeatability for CoQ10. An excellent linearity (r=0.999) was observed for CoQ10 in the concentration range $15.625{\sim}500\;{\mu}g/ml$ in dietary supplement. Observed recovery of CoQ10 was found to be between 98.33 and 99.38%. LOQ was found to be $250\;{\mu}g/ml$ Repeatability precision for CoQ10 was between 0.15 and 0.21% relative standard deviation (RSD). Further, limited studies showed that some adulterants and degraded material could be satisfactorily separated from CoQ10 and identified.

Indigestible carbohydrates as dietary fiber have attracted interest of consumers due to their several physiological benefits. Recent definitions of dietary fiber have included other indigestible carbohydrates such as resistant starch and resistant maltodextrins, which are natural, colorless, odorless and tasteless low-calorie food ingredients. Unlike some carbohydrates and digestible starches, indigestible starch and maltodextrin resist enzymatic hydrolysis in the upper gastrointestinal tract, resulting in little or no direct glucose absorption. In addition, there is increased microbial fermentation production of short-chain fatty acids in the large intestine. As an emerging functional low-calorie food ingredient, resistant starch and maltodextrin have been shown to have equivalent or superior impacts on human health compared to conventional fiber-enriched food ingredients. In this paper, the definition, strategies to enhance dietary fiber content in foods, some potential health benefits, and applications in food industry for indigestible starch and maltodextrin are summarized and discussed.

This study attempted to categorize the motivation for participation in leisure sports and analyze the difference in consumer demand for leisure sports wear according to the type. As a result of the analysis, the functionality of the preferred material consisted of movement, comfort, and body temperature maintenance. When purchasing, the factors to consider were extracted such as basic emphasis, emphasis on flaunting, and emphasis on practicality. The improvement requirement was composed of basic function improvement and various function additional factors, and the purchase satisfaction factor was composed of three factors: brand, practicality, design, and functionality. Motives for participation in marine leisure sports were grouped into mania, leisure, and health types. As for the functionality of the preferred material, the mania type and leisure type preferred movement, comfort, and body temperature maintenance functionality over the health type. As for the factors to consider when purchasing, the mania type and leisure type had higher consideration for the factors of basic emphasis, ostentation, and practicality than the health type. In the improvement requirements, both basic function improvement and various function additions had the highest mania type and the lowest health type. In terms of purchase satisfaction factors, practicality and brand were found to have a high leisure type, and functional factors were found to have a high mania type. For the enthusiastic group, it is thought that product development should focus on functionality and additional functions, and health types should be focused on design and utilization.

The purpose of this study was to investigate intake status and recognition of health functional foods by pre- and post-menopausal women in Seoul and Gyeonggi province. Survey questions were administered to 400 women around menopausal period, and data analysis was completed using the SPSS window program. Thirty-three percent of women recognized that they are healthy, and 47.1% of respondents are concerned with maintaining their health. However, respondents showed a low level of knowledge about the definition of menopause and health functional foods. Health concerns of respondents were significantly affected by marital status and level of education (P<0.05). Purchasing and intake of health functional foods was also significantly affected by health concerns and menopause symptoms (P<0.05). Twenty-nine percent of participants had taken health functional foods to prevent disease. However, most of them (85.9%) showed no knowledge of the main components of functional foods. In addition, knowledge associated with menopause and functional foods was affected by the level of education. The respondents' health concern, and thus purchase and intake frequencies of health functional foods, were affected by level of education. 'Effect of functional foods' was a top priority when respondents purchased health functional foods. The respondents answered black bean and pomegranate as foods that relieve menopause symptoms. However, they actually showed high intake frequency of black beans than pomegranate due to the high accessibility of black beans. The results of this study show that educational support for dietary guidelines is needed for middle-aged woman to be healthy after menopause.
