This study was conducted in order to monitor the extraction conditions for a gel-state beverage development of the Opuntia ficus-indica stem. Moreover, the organoleptic properties of the beverage prepared by the extract were optimized using the response surface methodology (RSM). The determination coefficient ($R^2$) value for the extraction yield of the stem was 0.95 (p<0.01). The maximum extraction yield was obtained at an extraction temperature of $93.02^{\circ}C$, 123 min of extraction time and 22.57 mL/g of water to sample. The beverage was prepared with the addition of xanthan gum, sugar and persimmon vinegar to the extract with a central composite design. The maximum organoleptic color of the beverage was obtained at 0.38% xanthan gum, 7.91% sugar and 0.76% persimmon vinegar. The maximum organoleptic flavor was obtained at 0.30% xanthan gum, 7.06% sugar and 1.26% persimmon vinegar. The maximum organoleptic taste was obtained at 0.22% xanthan gum, 10.36% sugar and 0.90% persimmon vinegar. The maximum overall palatability (3.92 score) of the gel-state beverage was obtained at 0.35% xanthan gum, 10.83% sugar and 1.21% persimmon vinegar.

In this study, various antioxidant propertieswere evaluated by analyzing the proximate composition and free-sugar and DNJ contents of the Bombyx mori L., Mori fructus, Morus ramulus, Mori folium, Dioscoreae rhizome and Inonotus obliquus extracts, and the antidiabetic effect was evaluated through an in-vivo experiment. Product evaluation was conducted after preparing a beverage for the easy use of the mixed extract for biological activity, as a functional resource. The biochemical composition of the extracts was 0.31% crude protein, 0.114 g/100 mL free sugar and 161.02 mg/gdw DNJ, all of which showed excellent results in all the antioxidant ability and ${\alpha}$-glucosidase inhibition ability experiments. The beverage showed the following functionalities. The total-polyphenol content was 71.93%, but the electron-donating ability was highest in the 5% extract concentration. Moreover, when the TBARS values were experimented on, KO2 showed an especially high scavenging ability. During the five-week beverage supply after inducing diabetes with streptozotocin (STZ), the change in the blood sugar was measured, and the STZ-induced diabetes+oral-beverage group (C) showed a lower blood sugar level than the diabetes comparative group (B) in the second week. In the STZ-induced diabetes+free-diet/beverage group (D), the blood glucose level also slowly decreased in the second week. The lowest blood glucose level among the STZ-induced diabetes groups was shown in the fifth week.

This study aims to examine the effects of integrated performance measurement on firm success of beverage businesses in Thailand. Integrated performance measurement, organizational commitment, organizational citizenship behavior, and firm success are the main variables of the study. In this study, all 653 beverage businesses from Department of Business Development, Ministry of Commerce, Thailand are the samples of the study. The data collection was provided during February - April, 2016. A mail survey procedure via questionnaire was used for data collection. 163 responses were received. Of the surveys completed and returned, 159 were usable. The structural equation model (SEM) is conducted to examine the effects of integrated performance measurement on organizational commitment, organizational citizenship behavior and firm success. The results show that integrated performance measurement positively influences organizational commitment, organizational citizenship behavior and firm success. Organizational commitment positively affects both organizational citizenship behavior and firm success while organizational citizenship behavior positively impacts firm success. In summary, integrated performance measurement as a strategic management accounting approach is a key determinant of firms' business outcome. Firms need to support their resources and capabilities in developing, implementing, utilizing, and maintaining integrated performance measurement. Potential discussion, conclusion, and suggestions and directions for future research are highlighted.

The purpose of this study is to investigate factors that affect menu navigation time and consumer trust in food and beverage(F&B) restaurants to analyze the menu's effect on impulse buying behavior. Based on the results of the analysis, this paper derives theoretical and practical implications to improve the growth and development of F&B restaurants located in airports. According to empirical analysis, it was proven menu browsing time has been found to strongly influence passengers' impulsive order behavior. A passenger with a strong "consumption ability" navigates the menu for a longer period, which increases the likelihood of impulsive purchases. Service appeal also has a significant influence on menu navigation time. Third-party certification did not appear to help build passenger confidence, thus yielding contradictory results compared to previous studies. Word of mouth had the strongest influence on trust formation. Finally, when passengers were satisfied with the menu items of F&B restaurants they had previously ordered, they tended to believe that the menu items they had not tried would also be good. In sum, impulsive menu orders have a direct impact on the profitability of F&B restaurants.

This study aimed to present data for the industrialization of Omija added onion fermented beverage (OOFB) development by analyzing the volatile flavor components. A total of 55 compounds, including 4 terpene derivatives, 9 esters, 5 aromatic compounds, 6 alcohols, 7 ketones, 3 aldehydes, 11 acids, 1 sulfur-containing compound, 8 furans and 1 other, were identified in OOFB. The content of fragrance components was high with 37.8% of acids and 29.0% of furans. 2,5-dimethyl thiophene, a sulfur compound, is a compound produced during the acetic acid fermentation of onion, and is thought to affect the onion flavor of OOFB.

The fermented fruit and vegetable mixed broth was prepared by using bacteriocin-producing lactic acid bacteria to evaluate the possibility of developing isotonic beverage with anticariogenic activity. Optimum conditions were also established to produce bacteriocin by a mixed culture system consisting of Lc. lactis and Leu. mesenteroides in a fruit and vegetable mixture. Production of bacteriocin was not observed when both strains were simultaneously innoculated, but pH adjustment of the broth fermented by Leu. mesenteroides to nearneutral pH stimulated the production of bacteriocin by Lc. lactis. The concentration of sodium of the fermented broth was higher than those of commercial products. Color change of the fermented broth was not observed during storage. The fermented broth showed strong inhibitory effect against Streptococcus mutans which is an oral inhabitant with a cariogenic activity. Bacteriocin activity in the fermented broth was retained very stable for 4 weeks at 4$\^{C}$. The results indicated that bacteriocin-producing lactic acid bacteria can be used for the preparation of a Korean style thirst-quenching beverage containing bacteriocin.

Wild grape juice was fermented by Gluconacetobacter hansenii TF-2 isolated from tea fungus, to develop a new acidic beverage (fermented wild grape beverage, WGB). Broth was prepared by fermentation of 11~17% (v/v) juice, and sweetened with sucrose (initial sucrose level: $10^{\circ}$ Brix). Fermentation was initiated by addition of 5% (w/v) seed gel (the pellicle of the tea fungus) which had been previously cultured in the same medium (freshjuice broth), and fermentation proceeded in the dark at $29{\pm}1^{\circ}C$ for about 15 days. The major acids produced were succinic acid, malic acid, and acetic acid. After 15 days of fermentation, the organic acid content (principally succinic acid) was 49.6 ppm in WGB 11 and 77.4 ppm in WGB 17. The free sugar content of WGB was 1063.6-1082.5 mg/mL, composed of unfermented fructose, glucose, and sucrose, in that order. The microbial inhibitory effects of the fermented beverage were most apparent when Gram-negative bacteria (Escherichia coli and Salmonella typhimurium) were tested; the inhibition rate was 34.46-88.00%. The new fermented beverage thus displays effective antimicrobial activity against some species of bacteria.

This study reviews the scientific management theories and discusses those theories within the food service industry. By providing the principles and the practical implications of the theories on the food service industry, this study tries to identify their philosophies and usefulness to the industry so that the managers in the industry use them in their dylmanic operations. In the fastly changing modern globalized world, we now face a situation where it's becoming more and more difficult to mange a restaurant business. In order to build a food industry business that can maintain a continuous development in today's business environment, one will have to apply the professional management theory in a cost-reduce strategy. It is more important though to have managers, organization members, in short, any person who can work to be motivated in accomplishing these two major issues-income increase and cost reduction. In this erawhere it's getting so difficult for researches on possible strategies for these business managers to overcome their difficulties. It is for certain that in the upcoming second millenium the travel and tourism industry will be one of the world's biggest industry worldwide. Korea's hotel industry has developed since the 1988 Seoul Olympic Games and has shown great amount of competition within the same business. Thus managers have become acquainted with the "know-how" strategy and the practical and scientific managemnet theories were introduced. This helped not only to increase income but also to maximize profit. However, rather than concentration on the "Hard-ware" aspect "Soft-ware" related professional management strategies were developed along with professionalism and human service were emphazied. As such, the actual cost of food and beverages are for the hotel industry business managers the biggest shortterm expense item. Due to the natural state of food items, there is a great chance of "Loss" in preservance, and this is the reason it is complicated to effectively maintain food. As a consequence, very often, the failure to managea hotel or restaurant depends on the capability of the food and beverage preservance mangement: on how they are able to manage effectively the original price of food and beverage. Finally, the main problem of the original price management of food and beverage in Korean hotels are: a) No fixation of set price b) The difficulty to calculate the price difference between a set price and an original price. c) Lack of professinalism in managing the food and beverage original price. d) Lack of perception of the highest ranking management personnels. So as to reform these matters it is necessary to : a) Reform on the management accounting system b) Emphasize to the people in charge on the idea of original price management c) Reinforce original price mangement prevention and assurance of indepedent inspection rights d) Reat manpower
