  • The objectives of this study were to evaluate the sensory properties of various natural flavor enhancers (NFEs) and to understand the effects of NaCl and temperature on the sensory characteristics of these NFEs. Descriptive analysis was conducted to evaluate six types of NFEs: yeast extract-based NFE, three; fish sauce-based NFE, one; soy sauce-based NFE, one; and hydrolyzed peptide NFE-based, one. The effects of NaCl (no addition vs. addition) and temperature ($20^{\circ}C$ vs. $55^{\circ}C$) were also evaluated. The results showed that the overall flavor intensity and sensory properties of the NFEs differed greatly depending on the NFE source. Two of the yeast extract-based NFEs elicited higher umami intensity than the other NFEs. Addition of NaCl increased some of the savory-related flavors and the perceived viscosity of the sample. Aroma intensities, in general, were enhanced at the higher temperature, whereas flavor, aftertaste, and mouthfeel attributes were perceived to be stronger at the lower temperature.

  • This study utilized the crust by-product from dry-aged beef as a flavor enhancer for brown sauce and analyzed its physicochemical and organoleptic properties. The physiochemical properties include proximate composition, color, pH, swelling yield, viscosity, and salinity. The organoleptic properties were studied through electronic nose and sensory evaluations. The moisture content of the samples decreased while fat and protein content increased as crust content increased (p<0.05). The lightness, yellowness, and redness increased with increasing crust content (p<0.05). The pH of the samples also increased as the crust content increased. The viscosity significantly increased while salinity decreased with increasing crust content (p<0.05). The aromatic profiles of the control and samples with 5% and 10% crust addition were distinguishable; however, samples with crust additives between 10% and 15% gave similar aromatic profiles. The taste of the control sample was significantly lower than that of the samples formulated with the crust (p<0.05), and the sensory viscosity of the samples with 10% crust was significantly higher than that of the control (p<0.05). Flavor and overall acceptability tended to increase with increasing crust content of up to 10% addition (p<0.05). These results show that the crust from dry-aged beef loin crust is a suitable natural flavor enhancer for brown sauce and improves its physiochemical and organoleptic properties.

  • 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.

  • The objective of this study was to determine the perception of monosodium glutamate (MSG) contents in eating out menu and MSG symptom complex. Respondents in the Seoul area were surveyed from Feb. 10 to 20, 2014. The results are summarized as follows. The 51.3% of respondents were male and 48.7% of them were female. As for age, 73.5% of respondents were 20~24 years old. Favorite menu of respondents' eating out were Korean food (57.8%), Western food (17.6%), Fast food (9.5%), Japanese food (6.2%), Chinese food (5.2%). Male respondents favored Korean food (62.4%), Fast food (10.2%) and Western food (9.6%), but female respondents favored Korean food (53.0%), Western food (26.2%) and Fast food (8.7%). The 48.7% of respondents considered Chinese food containing high amount of MSG. A few respondents (18.6%) recognized to usage amount of MSG as consideration factor to select eating out menu. However, most respondents (55.2%) perceived harmful to take excessive amount of MSG contained food. The 37.9% of respondents had experience of MSG symptom complex after eating out. Respondents' self recognized MSG symptom complex were thirstiness (84.5%), drowsiness (55.7%), weakness (34.5%), nausea (30.2%), tightness (20.7%) and headache (14.7%). The 19.9% of respondents like MSG contained food. The reason for disliking MSG contained food were 'bad for health' (66.3%) and 'MSG symptom' (33.2%). The reason for liking MSG contained food were 'good taste (83.6%) and 'habitual eating' (14.8%). The result of this study showed that some sensitive people have unpleasant reaction after eating out. Therefore, it is suggested that natural flavor enhancer may develop to replace the use of MSG.

  • 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.

  • Chronic inflammation is known to have effects on various diseases such as gout, cancer, dementia, atopic disease, and obesity. In addition, since some signal cascades involved in the development of inflammation are known to affect the damage and aging of the skin tissue, studies are being conducted actively to control the inflammation mechanism. In order to mitigate or prevent inflammatory response, a number of researches have been made to develop anti-inflammatory materials from some plants. In particular, Stevia rebaudiana produces steviol glycosides (SG), a natural sweetener with a distinctive flavor. Studies on some of SG have been shown to have anti-inflammatory activity. Researchers of this study expected that more SG also possess anti-inflammatory activity, besides stevioside, rebaudioside A, and steviol. In order to confirm this possibility, the researchers screened inhibition activity of various steviol glucosides for NO production in RAW 264.7 cell lines. As a result, steviol ${\beta}-glucopyranosyl$ ester (SGE) showed the highest inhibitory activity among steviol derivatives treated at the same molar concentration. In addition, we found that mRNA expression level of $interleukin-1{\alpha}$ ($IL-1{\alpha}$), $interleukin-1{\beta}$ ($IL-1{\beta}$), cyclooxygenase-2 (COX-2), nuclear factor kappa-light chain-enhancer of activated B cells ($NF-{\kappa}B$) and inducible nitric oxide synthase (iNOS) was also decreased in a dose-dependent manner. These results show that SGE inhibits anti-inflammatory activity and NO production in mouse macrophage RAW 264.7 cells. It was confirmed that SGE has potential to be applied as an anti-inflammatory material.
