  • Sodium chloride (NaCl) is a very important as one of major food ingredients in food industries. Recently, as the potential risk of adult diseases such as hypertension by overingestion of sodium, health authorities of many countries are executing policies for the reduction of sodium to suppress the overingestion of sodium by intake of NaCl. As general ways, the replacement of NaCl with either alternative salts, such as solar salts and minerals, for examples calcium, magnesium, potassium, lactic acid, and so on, and the addition of flavor enhancers were used to reduce the contents of sodium in foods. Recently, controls of particle size of sodium chloride or release point are emerging as new salt-manufacturing technologies for the sodium reduction. Upon reducing NaCl in foods it is important to develop practically adaptable technologies on the basis of the consideration of the unique functions of NaCl in foods, in particular effects on rheological characters, function as a humectant, shorten shelf life time, and so on.

  • This study was carried out to find a cholesterol removal rate, flavor development and bitter amino acid productions in Cheddar cheese treated with $\beta$-cyclodextrin (CD): 1) Control (no homogenization, no $\beta$-CD), and 2) Milk treatment (1000 psi milk homogenization, 1% $\beta$-CD). The cholesterol removal of the cheese was 79.3%. The production of short-chain free fatty acids (FFA) increased with a ripening time in both control and milk treated cheese. The releasing quantity of short-chain FFA was higher in milk treated cheese than control at 5 and 7 mo ripening. Not much difference was found in neutral volatile compound production between samples. In bitter-tasted amino acids, milk treatment group produced much higher than control. In sensory analysis, texture score of control Cheddar cheese significantly increased with ripening time, however, that in cholesterol-reduced cheese decreased dramatically. Our results indicated that the cheese made by $\beta$-CD treated milk with low pressure homogenization showed an effective cholesterol reduction and a rapid cheese ripening, while no capture of flavor compounds by $\beta$-CD.

  • We investigated the antioxidant, physicochemical, and sensory characteristics of dried type sodium reduced chicken bibimbap using dandelion complex extract powder of AF-343 (DCEP) as a home meal replacement. The DCEP is known to add moisture to the skin and to relieve the symptoms of atopic dermatitis. The sodium content of the standard sample was 1,190 mg per serving. The sodium was significantly reduced by 30%, resulting in 820 mg of sodium for the reduced-sodium group (p<0.05). The ash contents of the standard sample group with the DCEP showed significantly the highest value at 6.01% in all of the samples as affected by the minerals of the DCEP (p<0.05). Sensory characteristics of savory aroma, savory flavor, cooked vegetable flavor and hardness in all the samples did not show significant differences, implying that addition of DCEP and 30% sodium reduction did not have undesirable effects on those sensory attributes. Furthermore, chicken flavor, which was a bit oily in the standard samples tended to decrease slightly, leaving a desirable savory flavor increased in the reduced sodium groups. In acceptance tests, the samples did not show any significant differences, indicating that the DCEP added sodium-reduced samples may be potentially acceptable to consumers. Total flavonoid contents, ABTS and DPPH radical scavenging activity, indicators of biologically active ingredients such as antioxidant, anticancer, and antibacterial activities significantly increased with the amount of DCEP added (p<0.05).

  • Effects of pH (1.8-10.2) and time (56 sec-15 min 4 sec) at high hydrostatic pressure (500 MPa) on the reduction of volatile compounds in garlic were studied. Volatile components of garlic were obtained from the headspace, analyzed, and identified by gas chromatography (GC)-mass spectrometry and an electronic nose. Nineteen sulfur compounds were identified as major compounds in garlic, and furan, aldehydes, alcohols, and ketones were also detected. Off-flavor compounds were more effectively reduced under strong acidic conditions. As the residence time at 500 MPa increased from 56 sec to 15 min 4 sec, the total amount of volatile compounds decreased significantly. The total amount of sulfur compounds decreased about 70% compared to those of raw garlic when the garlic was soaked in buffer (pH 6.0) and treated at 500 MPa for 15 min 4 sec. A principal component analysis showed that the off-flavors of garlic were reduced by the operating time of high hydrostatic pressure as well as pH treatment. The correlation coefficient of the results between GC and the electronic nose analysis was 0.9620. Therefore, pH and high hydrostatic pressure treatment could be used as an efficient method for reducing of garlic off-flavor.

  • In this study, the physicochemical properties, antioxidant capacities, and volatile flavor compounds of oriental melon wine prepared by freeze concentration after heat treatment (HA), ascorbic acid treatment (AAT), and heat and ascorbic acid treatment (HAAT) were investigated. During fermentation period, the melon wine by HAAT showed greater reduction of soluble solids and reducing sugar contents compared to other treatments. In addition, the melon wine treated with HAAT also showed a higher L value and lower browning index compared to other treatments. After aging, free sugar including fructose, and organic acids including citric acid, succinic acid, and malic acid were detected in all samples. For antioxidant activities and contents, HAAT treated wine showed greater antioxidant activities and total phenolic contents than those of others. In GC/MS analysis, a total of 33 volatile flavor compounds were identified. In the principal component analysis of volatile flavor compounds, principal components 1 and 2 represented 88.15% of the whole date distribution and showed opposite tendencies. Taken together, HAAT enhanced the antioxidant activities and sensory properties of oriental melon wine. Moreover, freeze concentration gave the different volatile flavor characteristics in oriental melon wine.

  • The objective of this study was to reduce Nuruk flavor in Korean rice-distilled liquor using different ratios of $Sumizyme^{TM}$ and Nuruk. After 9 days of fermentation at $28^{\circ}C$, alcohol contents and pH were 16.0~17.1% and 3.82~4.16, respectively. An increased ratio of $Sumizyme^{TM}$ decreased alcohol content while increased pH of the mash. In alcohol contents, there were no significant differences up to 30% substitution of Nuruk to $Sumizyme^{TM}$. A descriptive analysis was conducted with trained panelists for determining the intensity of Nuruk flavor. The intensities of Nuruk flavor in mashes and distilled liquors brewed by traditional Nuruk, cultured Nuruk, and a mixture of 30% $Sumizyme^{TM}$ and 70% cultured Nuruk were evaluated. The mash and distilled liquor prepared using a mixture of 30% $Sumizyme^{TM}$ and 70% cultured Nuruk showed significantly lower intensities of Nuruk flavor when compared with those of mashes and distilled liquors produced by the traditional and cultured Nuruk.

  • Sodium is a component of salt and naturally taken in the process of taking in table salt. For food processing, salt is very important. In general, salt adds flavor and taste including a salty taste and rheologically, it plays an important role in forming tissues. Also, it helps in improving preservability of food by controling growth of microorganisms. But excessive intake of salt has been blamed for outbreak of high blood pressure, heart disease, stroke, osteoporosis, kidney stone, stomach cancer and others. For this reason, there are active efforts to reduce sodium of processed foods all around the world. In Korea, a guideline for sodium reduction in 27 items and 44 kinds of foods including confectionery was suggested as part of the 'processed food sodium reduction guideline development project', which has been conducted since 2012.

  • In the saponification to manufacture plant fatty acid hard soap, the drying process is required for its water evaporation and hardness. This study mixed it with essential oil(E.O) with high volatility instead of adding synthetic flavor. And it comparatively observed the duration of flavor changing to the additive ($TiO_2$) and the drying period of the major flavor component (Linalool, Linalyl acetate) in the essential oil (Lavender E.O) contained in the soap during the soap manufacture by using GC-MS. Advanced researches have mostly dealt with the utility of plant hard soap, and those related with the volatility of flavor have been hardly conducted. Regarding the volatility of linalool contained in the soap, the soap mixed with $TiO_2$ showed a higher reduction ratio up to the 12th week; however, at the point of the 20th week, it reduced to a similar level. Although Linalyl acetate did indicate a slight difference according to the mixture of $TiO_2$, the volatility was shown similar up to the point of the 20th week. During the 20 weeks of drying, the residual rate of linalool was found to be higher than that of Linalyl acetate regardless of the mixture of $TiO_2$. It has been found that the flavor component of lavender essential oil with the duration of two or so days at the room temperature remains for 20 weeks (or 5 months) when it is manufactured through the mixture of plant fatty acid hard soap.

  • This study was carried out to investigate the effect of phytosterol ester addition on lowering blood cholesterol in cholesterol-reduced Cheddar cheese. For cholesterol removal, separated cream was treated with 10% ${\beta}$-cyclodextrin at 800 rpm, then blended with remaining skim milk and homogenized with 1,000 psi at $70^{\circ}C$. Experimental cheeses were manufactured by five different levels of phytosterol addition. After the cholesterol reduction process by ;${\beta}$-cyclodextrin, the cholesterol removal rate was in the range of 91.0 to 92.1%. Amount of short-chain free fatty acid and free amino acids increased with an increase of phytosterol ester, and those were significantly different from that of control in all ripening periods. All rheological properties also increased with an increase of phytosterol ester during ripening period. In sensory analysis, the scores of rancid, bitterness Cheddar flavor and off-flavor intensities increased significantly, while texture was decreased during ripening in phytosterol ester-added groups. Total blood cholesterol was reduced by 18% when rats were fed Cheddar cheese treated with 8% phytosterol. The present study indicated that phytosterol ester addition resulted in a profound lowering effect of blood with cholesterol-reduced Cheddar cheese.
