  • This survey was carried out using a self-administered questionnaire in order to investigate the flavor enhancer products questionnaires were used out of 505 collected (collection rate : 84.2%). Most housewives used flavor enhancer products. Housewives with higher educations and employed housewives used significantly less flavor enhancer. The main reason for nonuse of flavor enhancer products was their perceived negative health effects. Housewives mainly used flavor enhancer products in stews and whole dishes. Most housewives used flavor enhancer products 1-2 times per day and housewives with higher educations and employed housewives used flavor enhancer products less frequently. As for the quantity of flavor enhancer products used, most housewives reported small to moderate amounts. Housewives with higher educations used significantly smaller amounts of flavor enhancer products. There was a significant difference in the kinds of flavor enhancer products used by housewives, depending on education level, household income, food expenditures and residence type. Most housewives purchased flavor enhancer products at wholesale marts. There was a significant difference in the places where flavor enhancer products were purchased among those of different education and household income levels. Therefore, these results may be useful in the development of safer and more variously flavored flavor enhancer products.

  • Sodium chloride is an important ingredient added to most of foods which contributes to flavor enhancement and food preservation but excess intake of sodium chloride may also cause various diseases such as heart diseases, osteoporosis and so on. Therefore, this study was carried out to investigate the effect of monosodium glutamate (MSG) as a salty flavor enhancer on the quality and sensorial properties of the NaCl/MSG complex and actual food system. For characterizing the spray-dried NaCl/MSG complex, surface dimension, morphology, rheology, and saltiness intensity were estimated by increasing MSG (0-2.0%) levels at a fixed NaCl concentration (2.0%). MSG levels had no effect of the characteristics of the NaCl/MSG complex, although the addition of MSG increased the surface dimension of the NaCl/MSG complex significantly (p<0.05). Furthermore, the effect of MSG on enhancing the salty flavor was not observed in the solution of the NaCl/MSG complex. In the case of an actual food system, model meat products (pork patties) were prepared by replacing NaCl with MSG. MSG enhanced the salty flavor, thereby increasing overall acceptability of pork patties. Replacement of NaCl with MSG (<1.0%) did not result in negative sensorial properties of pork patties, although quality deterioration such as high cooking loss was found. Nevertheless, MSG had a potential application in meat product formulation as a salty flavor enhancer or a partial NaCl replacer when meat products were supplemented with binding agents.

  • The aim of this research was to enhance the flavor of visceral extracts from skipjack tuna. Flavor precursors and the optimum condition for the Maillard reaction were determined. The flavor extract was prepared from the tuna viscera using Endo/Exo Protease controlled in 3 factors; temperature, enzyme amounts and incubation time. The optimal condition for producing tuna viscera protein hydrolysate (TVPH) was 60℃, 0.5% enzyme (w/w) and 4-hour incubation time. TVPH were further processed to tuna viscera flavor enhancer (TVFE) with Maillard reaction. The Maillard reactions of TVFE were conducted with or without supplements such as xylose, yeast extract and methionine. The Maillard volatile components were analyzed with gas chromatography-mass spectrometry. Sixteen volatiles such as 2-methylpropanal, methylpyrazine, 2,5-dimethylpyrazine, dimethyl disulfide and 2-acetylthaizone were newly formed via Maillard reaction and the similarity of volatile contents from TVPH and TVFE were virtualized using Pearson's correlation integrated with heat-map and principal component analysis. To virtualize aromagram of TVPH and TVFE, odor activity value and odor impact spectrum (OIS) techniques were applied. According to OIS results, 3-methylbutanal, 2-methylbutanal, 1-octen-3-ol 2,5-dimethylpyrazine, methional and dimethyl trisulfide were the potent odorants contributed to the meaty, creamy, and toasted aroma in TVFE.

  • Pork cutlets containing ginseng powder 1% + ginseng distillate 1%(P1/D1), ginseng powder 2%(P2), ginseng powder 1.5% + ginseng distillate 1.5%(P1.5/D1.5) and ginseng powder 3%(P3) were manufactured and compared with the control(no ginseng powder and distillates) in meat quality, sensory evaluation and flavor intensity. The L values were significantly lower and a values were significantly higher for pork cutlets containing ginseng additives as compared to the control. The pork cutlets containing ginseng powder and distillates were higher in hardness only at the beginning stage, but no significant differences in springness, cohesiveness and chewiness among the treatments were observed during storage at -20$^{\circ}C$ for 8 weeks. Flavor analysis indicated that spathulenol, panasinsanol, neointermedol and ginsenol were responsible for ginseng flavor. The sensory panels detected most intense ginseng flavor and taste for pork cutlet which contained combination mixtures of ginseng powder 1.5% and distillate 1.5%. In conclusion, sensory panels evaluated that ginseng distillates produced intense ginseng flavor and enhanced ginseng flavor when used as mixtures with ginseng powder. Therefore, ginseng distillates can be used as a natural antioxidant and flavor enhancer in pork products.

  • In light of addressing consumer health concern, coping with anti-tobacco movement, and promoting new product, tobacco industry is actively pursuing to make a new generation of cigarettes with low tar and nicotine deliveries, and less harmful substances. Low tar and low nicotine cigarettes increases their market shares dramatically world wide, especially in KT&G, multinational tobacco companies, EU countries, even in China regulated by CNTC to set up yearly target to lower tar and nicotine deliveries. On the other hand, to design a new cigarette with reduced harmful substances begins to gain speed. The "modified Hoffmann list" publishes thirty plus substances in tobacco leaf and main smoke stream, which is the prime suspect causing health problems. Various ways and means are developed to reduce such components including new tobacco breeds, new curing method, tobacco leaf treatment before processing, selected filtration system, innovated casing system to reduce free radicals, as well as some non conventional cigarette products. In TSRC held this year, the main topic is related to reduce tobacco specific nitrosamines in tobacco leaf. The new generation of cigarette is in the horizon. It still needs a lot help to produce commercial products with satisfied taste and aroma characters. The flavor industry is not regulated by many governments demanding which ingredients might or might not be for tobacco use. However, most of the cigarette companies self impose a list of ingredients to guide flavor suppliers to design flavors. Unfortunately, the number of ingredients in those lists is getting shorter every year. It is understandable that the health is not the only reason. Some cigarette companies are playing safe to protect the company from potential lawsuit, while others are just copying from their competitors. Moreover, it is obvious that it needs more assistance from casings and flavors to design new generation of cigarettes with missing certain flavor components in tobacco leaf and main smoke stream. These flavor components are either non-existed or at lower level at new form of cured tobacco leaf or filtered in the main smoke stream along with reduced harmful substances. The use of carbon filters and other selected filtration system poses another tough task for flavor system design. Specific flavor components are missing from the smoke analysis data, which brings a notion of "carbon taste" and "dryness" of mouth feel. It is ever more demanded by cigarette industry to flavor suppliers to produce flavors as body enhancer, tobacco notes, salivating agents, harshness reducer, and various of aromatic notes provided they are safe to use. Another trend is that water based flavor or flavor with reduced ethanol as solvent is gaining popularity. It is preferred by some cigarette companies that the flavor is compounded with all natural ingredients or all ingredients should he GMO free. The new generation of cigarettes demands many ways of new thinking process. It is also vital for tobacco industry. It reflects the real needs for the consumers that the cigarette product should be safe to use as well as bearing the taste and aroma characters smokers always enjoyed. An effective tobacco flavor system is definitely a part of the equation. The global trend of tobacco industry is like trends of any other industries lead by consumer needs, benefited with new technology availability, affected by the global economy, and subjected for various rules and regulations. Anti-tobacco organizations and media exceptionally scrutinize cigarette, as a legal commercial product. Cigarette is probably the most studied commercial product for its composition, structure, deliveries, effects, as well as its new developmental trend. Therefore, any new trend of cigarette development would be within these boundaries. This paper is trying to point out what it would be like for tobacco industry in the next few yews and what concerns the tobacco industry. It focuses mostly on the efforts to produce safer cigarettes. It is such a vital task for the tobacco industry and its affiliate industries such as cigarette papers, filters, flavors, and other materials. The facts and knowledge presented in this paper might be well known for the public. Some of the comments and predictions are very much personal opinion for a further discussion.

  • Acetoin is generated by numerous microorganisms using ${\alpha}$-acetolactate decarboxylase (ALDC) to prevent overacidification of cells and their environment and to store remaining energy. Because acetoin has been used as a safe flavor enhancer in food products, industries have been interested in biotechnological production of acetoin using ALDC. ALDC is a metal-dependent enzyme that produces acetoin from ${\alpha}$-acetolactate through decarboxylation reaction. Here, we report the crystal structure of ALDC from Bacillus subtilis subspecies spizizenii (bssALDC) at $1.7{\AA}$ resolution. bssALDC folds into a two-domain ${\alpha}/{\beta}$ structure where two ${\beta}$-sheets form a central core. bssALDC assembles into a dimer through central hydrophobic interactions and peripheral hydrophilic interactions. bssALDC coordinates a zinc ion using three histidine residues and three water molecules. Based on comparative analyses of ALDC structures and sequences, we propose that the active site of bssALDC includes the zinc ion and its neighboring bssALDC residues.

  • Salt, or sodium chloride (NaCl), is a critical ingredient in many foods. It has roles in the flavor profiles of food products, textures of foods and preservation of foods against microbes. However, it increases risks of hypertension and is closely related to the development of cardiovascular disease. In recent years, health concerns related to sodium intake caused an increased demand for salt-reduced products in worldwide; it became necessary to develop natural salt-alternative products that are globally competitive. In a recent study, researchers succeeded in obtaining a natural salt enhancer through the hydrolysis of vegetable- and animal-matter mixtures. This study used various methods to identify and quantify peptide-containing arginine as a salt-alternative peptide (SAP) in an optimum combination. Arginine, or dipeptide-containing arginine, was analyzed as a standard substance using an NMR spectroscopy. The NMR carbon signal of the guanidine group of the standard substance was verified in a similar location (the L-arginine (Arg) was 156.8 ppm, the Arg-Alanine was 156.4 ppm and the Arg-Serine was 156.4 ppm). The results suggested that it is possible to analyze peptide-containing arginine quantitatively through the hydrolysis of vegetable- and animal-matter mixtures.

  • To utilize oyster cannery processing waste water effectively, this study was carried out to prepare instant powdered soup using oyster wash water. Instant powdered soup from oyster hot-water extracts (HWE) was prepared by mixing oyster spray-dried hot-water extracts (15 g) with table salt (5 g), cream powder (19 g), milk replacer (12 g), wheat flour (20 g), corn flour (15 g), starch (5 g), glucose (7.5 g) and onion powder (1.5 g). In preparing instant powdered soup from oyster wash water (OWW), powder from oyster spray-dried wash water instead of the spray-dried hot water extracts, was added and other additives were added in proportion to those in the HWE. The OWW consists mainly of carbohydrates (71.1%). It was not different from the instant powdered soup from hot-water extracts. The volatile basic nitrogen, vaible cell counts, coliform group of instant powdered soup from oyster wash water contains 29.4 mg/100g, $4.6{\times}10^4\;CFU/g$, <18 MPN/100g, respectively and its water activity has 0.246. So it was a hygienically safe and conservable instant food. The main fatty acid of OWW was 16 : 0 and 18 : 1n-9. Its chemical score of protein was 59.4% and its main inorganic matter was iron. According to a sensory evaluation, in contrast to the HWE, the OWW had a slightly lower aroma but better taste. It was concluded from the above chemical and sensual evaluation that the oyster wash water can be used as a flavor enhancer for instant powdered soup.
