  • The objective of this study was to evaluate the effect of functional herbal foods on the growth of intestinal lactic acid bacteria. When Bifidobacterium breve and human intestinal microflora were inoculated in the general anaerobic medium which contained each functional food water extract, most of functional herbal foods induced the growth of lactic acid bacteria by decreasing pH of the broth. The pH decreasing effects of Liriipe platyphylla and Platycodon grandiflorum were excellent. The growth of lactic acid bacteria effectively inhibited the bacterial enzymes, $\beta$-glucosidase and $\beta$ -glucuronidase. Eugenia caryophyllata and Liriipe platyphylla potently inhibited the productivity of P -glucosidase of B. breve and human intestinal bacteria. Cinnamomum cassia, Gardenia jasminoides and Platycodon grandiflorum potently inhibited the productivity of $\beta$-glucuronidase of human intestinal bacteria. The growth component isolated from Platycodon grandiflorum was sucrose (compound B).

  • We investigated the anti-diabetic activity and enzymatic activity of 24 commercial doenjang samples certified for traditional foods. Twenty four doenjang samples showed the wide ranges in enzymatic activities (protease activities 0-50.45 unit/g, ${\alpha}$-amylase activities 0-675.9 unit/g, ${\beta}$-amylase 13.6-308.6 unit/g), and there were no difference in enzymatic activity by the producing region. To evaluate the potential anti-diabetic activity of 24 doenjang samples, we examined the effect of doenjang methanol extract (DME) on 2-[n-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl) amyno]-2-deoxy-d-glucose (2-NBDG) uptake. Ten samples among 24 samples significantly stimulated the uptake of 2-NBDG. When the cells were treated with DME at 400 ug/mL, No. 17 and 23 specially stimulated 2-NBDG uptake by 1.23-fold and 1.25-fold, respectively, compared with untreated control cell. And there were no cytotoxicity in the C2C12 cells treated with DME at concentration of 500 ug/mL. Among 24 samples, No. 6, 7, 12, 21 and 24 showed the ${\alpha}$-glucosidase inhibitor activity at concentration of 10 mg/mL; however, they were less effective than acarbose which is a commercial ${\alpha}$-glucosidase inhibitor.

  • Fermentation is an effective process for providing various beneficial effects in functional beverages. Lactic acid bacteria and yeast fermentation-based biotransformation contribute to enhancement of nutritional value and digestibility, including lactose intolerance reduction and control of infections. In this study, the probiotic fermented fruit juice (PFJ) was produced by Lactobacillus plantarum TISTR 1465, Lactobacillus salivarius TISTR 1112, and Saccharomyces boulardii CNCM I-745 while mixed fruit juice (MFJ) was used as the basic medium for microorganism growth. The potential function, the anti-salmonella activity of PFJ, was found to be effective at 250 mg/ml of MIC and 500 mg/ml of MBC. Biofilm inhibition was performed using the PFJ samples and showed at least 70% reduction in cell attachment at the MIC concentration of Salmonella Typhi DMST 22842. The antioxidant activities of PFJ were determined and the results revealed that FSB.25 exhibited 78.40 ± 0.51 mM TE/ml by FRAP assay, while FPSB.25 exhibited 3.44 ± 0.10 mM TE/ml by DPPH assay. The volatile compounds of PFJ were characterized by GC-MS, which identified alcohol, aldehyde, acid, ester, ketone, phenol, and terpene. The most abundant organic acid and alcohol detected in PFJ were acetic acid and 2-phenylethanol, and the most represented terpene was β-damascenone. The sensory attributes showed scores higher than 7 on a 9-point hedonic scale for the FPB.25, illustrating that it was well accepted by panelists. Taken together, our results showed that PFJ could meet current consumer demand regarding natural and functional, fruit-based fermented beverages.

  • This study attempted to examine the subjectivity of consumers of the MZ generation in their 20s on health functional foods, which have recently emerged as hot consumption items. A study was conducted using the Q methodology to examine the characteristics, meanings, and values of the younger generation in the health functional food market represented by red ginseng, vitamins, and probiotics. Using the QUANL analysis program, a total of 37 Q samples and 30 P samples were used in the study, and three types with unique tendencies were found. The first type discovered through this was named "YubiMuhwan(Forewarned, forearmed; 有備無患)", the second type was "Bansinbanui(half confident; 半信半疑)", and the third type was called "Silsagushi(empirical tradition; 實事求是)". Reflecting these attributes, various strategic ideas were presented for the classification of new characteristics and consumers in the health functional food market and promotion of sales.

  • It's not easy to detect the high quality and functional compounds for control quality of food materials. The electronic nose was an instrument, which comprised of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system, capable of recognizing simple or complex odors. It can conduct fast analysis and provide simple and straightforward results and is best suited for quality control and process monitoring in the field of functional foods. Numbers of applications of an electronic nose in the functional food industry include discrimination of habitats for medicinal food materials, monitoring storage process, lipid oxidation, and quality control of food and/or processing with principal component analysis, neural network analysis and the electronic nose based on GC-SAW sensor. The electronic nose would be possibly useful for a wide variety of quality control in the functional food and plant cultivation when correlating traditional analytical instrumental data with sensory evaluation results or electronic nose data.
