This research was accomplished to analyze the preference and the actual using patterns of the bakery products using functional ingredients by subjects' age. This survey was examined by the self-administered questionnaire method for 374 female subjects in Suwon. All respondents preferred breads than confectionaries with functional ingredients. As for the products of cooking ingredients, cookies, roll-cake, cake, chocolate, the preference of teenagers was higher than those of the other groups. Subjects preferred potatoes, fruits, rice and green tea as functional ingredients. Over thirties showed the high preference over beans, vegetables, mushrooms, ginseng and oriental herbs while fruits were highly preferred in teenagers and twenties. The ratio of using the bakery products with functional ingredients once or twice a week was higher in over thirties than those of the other groups. Subjects answered that they generally spent $3,000won\sim5,000won$ on those products. Functionality of products was considered as the more important factor in thirties than in the other groups. The lack of information about these products and functional ingredients was reported by teenagers and twenties. These results would be basic data for marketing or improvement of baking products with functional ingredients.

The level of fat and salt can affect the product quality and storage stability of processed meats. Additionally, consumers' demands require dietary guidelines for developing low-fat/salt functional foods. Microbial transglutaminase (MTGase), which enhances textural properties by catalyzing protein-protein cross-linkages, was introduced to develop healthier lowfat/salt meat products. The potential possibilities of low-fat/salt processed meats were reviewed under optimal conditions for functional ingredients from several previous studies. The addition of non-meat protein (e.g. sodium caseinate and soy protein isolates), hydrocolloids (e. g. konjac flour, carrageenan, and alginates), and MTGase alone or in combination with other functional ingredients improved textural and sensory properties similar to those of regularly processed meats. When MTGase was combined with hydrocolloids (konjac flour or sodium alginate) or other functional ingredients, gelling properties of meat protein were improved even at a low salt level. Based on these reviews, functional ingredients combined with new processing technologies could be incorporated into processed meats to improve the functionality of various low-fat/salt meat products.

In this study, we analyzed the database for items reported to Korea Food and Drug Administration as for manufactured health/functional food during 2010. There were 183 health functional food products manufactured in domestic having over 2 functional ingredients (hereinafter, combinational health functional food) among total 7319 products. Among 183 products, there were 177 products having over two kinds of functional ingredient and 6 products were over 3 ingredients. The most commonly used functional ingredients in the combinational health functional food were Garcinia cambogia extracts which were used in 41 products, Octacosanol and Saw Palmetto extract. When we searched the safety information for the pair of ingredients used in combinational health functional food using several database, there were no reports for safety concern. However, as there are still safety concerns when intake various functional ingredients at once, we suggested to enforce the reporting system of adverse event in order to strength safety management of health functional food. With these complement, the safety management of health functional food might be achieved including a combinational products.

Dyslipidemia, defined as elevated triglyceride (TG), total- and LDL-C, and/or decreased HDL-C levels, is considered a principal risk factor for cardiovascular disease. The low-density lipoprotein receptor (LDLR) family has been considered a key player in the prevention of dyslipidemia. The LDLR family consists of cytoplasmic membrane proteins and plays an important role not only in ligand-receptor binding and uptake, but also in various cell signaling pathways. Emerging reports state that various functional ingredients dynamically modulate the function of the LDLR family. For instance, oats stimulated the LDLR function in vivo, resulting in decreased body weight and improved serum lipid profiles. The stimulation of LRP6 by functional ingredients in vitro activated the Wnt/${\beta}-catenin$ pathway, subsequently suppressing the intracellular TG via inhibition of SREBP1, $PPAR{\gamma}$, and $C/EBP{\alpha}$. Furthermore, the extract of Cistanchetubulosa enhanced the expression of the mRNA of VLDLR, followed by a reduction in the serum cholesterol level. In addition, fermented soy milk diminished TG and total cholesterol levels while increasing HDL-C levels via activation of LRP1. To summarize, modulating the function of the LDLR family by diverse functional ingredients may be a potent therapeutic remedy for the treatment of dyslipidemia and cardiovascular diseases.

This study was carried out to develop a new product using Cheonggukjang (fermented soybean product) and sub-ingredients(lactic acid bacillus powder, chlorella, lactose, green tea). Fresh Cheonggukjang was dried by a infrared drying(50℃, 36hr) and powdered by a roll mill. The powder was mixed with sub-ingredients and then moulded as tablet type by a press moulder. The pH of tablet was low with the addition of lactobacillus and total sugar content was high with the addition of lactose. Disintegration, absorption capacity and textural properties of tablet were not affected by the addition of any sub-ingredient. Color of non-added tablet was yellow to red, but changed to green when chlorella was added. Sensory properties(color, taste, flavor, chewiness, hardness, acceptability) were not affected by the addition of sub-ingredients. The results indicate that functional healthy tablet could be made from Cheonggukjang powder and various sub-ingredients.

In 2022, the domestic production performance of functional cosmetics in South Korea reached 4.6 trillion won, accounting for 33.85% of the total cosmetics production. The number of functional cosmetics reviewed increased by about 7.5% from the previous year, totaling 974 items. Especially with the increasing importance of the skin barrier function due to skin sensitivity caused by various environmental pollutants, domestic cosmetic companies are showing interest in the development of new ingredients and products related to this area. This study aims to analyze academic research trends related to in vitro experiments for the development of cosmetics improving the skin barrier, to provide practical information for the cosmetic industry. The findings are as follows: Academic research mainly focused on the efficacy of natural ingredients in improving the skin barrier, but there is a significant lack of quantitative accumulation of research. For the development of skin barrier-improving cosmetic ingredients, efficacy evaluation indicators were set, including hyaluronic acid production, expression of filaggrin gene, loricrin, formation of cornified envelope (CE), and expression of ceramide synthesis enzyme genes. Moreover, effective cosmetic ingredients for improving the skin barrier included lemongrass and perilla leaf extracts, flavonoids, Lactococcus lactis subsp. lactis, Exosomelike Nanovesicles derived from apple callus, Eleutherococcus sessiliflorus, Acanthopanax sessiliflorus, Eleutherococcus gracilistylus, Acer okamotoanum extracts, Aloe vera adventitious root extract, ethanol extract of Aruncus dioicus, and organic solvent fraction of Dracocephalum argunense.

The heat-mediated reflux apparatus extraction of Paeonia lactiflora Pall. has been widely used as a traditional extraction method. In this paper, the microwave apparatus extraction method of Paeonia Radix was performed and the active ingredients and functional constituents were compared with the reference extraction method. The most effective extraction condition of albiflorin using the microwave was 120℃ in 50% methanol, and paeoniflorin was maximally extracted at 60℃. The reduced level of paeoniflorin molecule at high-pressure and high-temperature extraction condition was caused by the molecular instability. Additionally, the microwave extraction of 50% methanol extracts at 150℃ showed the highest functional constituents determined by in vitro DPPH radical scavenging activity, polyphenol concentration, and tyrosinase inhibition assay. The microwave apparatus was adapted as a rapid, low-cost, and environmentally friendly method to extract active ingredients and the practical extraction conditions of Paeonia Radix can be used in industrial applications.
