  • Purpose: Technology and innovation drive new mobile application for ojek online. Using the theory of technology acceptance model and perceived risk theory, the researcher wants to find how these factors affect user's intention to use GO-FOOD that leads to technology adoption. Research design, data and methodology: The researcher uses GO-FOOD users that located in East Java, Indonesia for the object of study. Results: The findings of the research discovered that perceive usefulness and perceive ease of use do not significantly affect user's behavioral intention while perceive risk is significantly affecting the user's behavioral intention. Conclusions: The findings suggested that GO-FOOD or similar application should focus more on reducing or eliminating user's perception of risk towards the mobile application

  • The present study was performed to obtain data that could be used to popularize yakju(Korean traditional rice wine) by surveying how well rice wine goes with pairing foods. The survey was given to 302 men and women living in the Seoul and Gyunggi areas and work in the food service industry. The Jeon group, Gui group, Jeongol and Jjigae group, Pyeonyuk and Bossam group, and Muchim group were selected as menu items that go well with available rice wines. The survey aimed to identify foods that go well with four rice wines with different sensory characteristics. The survey results showed that both men and women replied that rice wines with Nuruk aroma and Nuruk taste go well with the Jeon group, rice wines with sour and flower aromas and common characteristics go well with the Muchim group, and rice wines with sweet and fruit tastes go well with the Muchim group. However, men and women had different opinions on rice wines having ginseng, soil, and herbal medicine aromas. Men replied that such rice wines go well with grilled meat, whereas women replied that these rice wines go well with Pyeonyuk and Bossan groups.

  • The effect of glucose oxidase (GO) and superoxide dismutase (SOD) on the oxidative stability of fish oil was investigated from oxygen content and peroxide value determinations of oil samples stored in vial. GO could inhibit the oxidation of the oil by removing headspace oxygen. When SOD was solubilized in the oil, peroxide value was slightly lower than that of a control, indicating that the enzyme also had an effect on retarding the oxidation.

  • The study indicated that antimicrobial activity about gram positive and gram negative bacteria of ginger-oleoresin(GO) extract with the condition of ethanol and supercritical fluid extractions. As the concentration of extraction increases, the clear zone of GO ethanol extract also increased dependently. This led the antimicrobial activity of gram positive bacteria to take bigger place than gram negative bacteria especially in Listeria monocytogenes. There was a high antimicrobial activity in E-III treatment where the ratio of the ginger powder extract to ethanol extraction was 1:6. It was quite effective to treat the antimicrobial activity of GO ethanol extract under $80^{\circ}C$ and there was not big difference in the intervals which were the extraction time - 1 to 7 hours. The antimicrobial activity of supercritical fluid extract seemed to take the biggest place in Listeria monocytogenes. From the supercritical fluid extract, it was shown the strong ability of antimicrobial activity in the condition with 100 bar $35^{\circ}C$, 250 bar $35^{\circ}C$ and 250 bar $65^{\circ}C$. Furthermore, according to the case of solvent extract, there was not any significant difference in the antimicrobial activity with condition of extraction. However, there was significant antimicrobial activity in E-III treatment of 100 bar and 500 bar of extraction pressure, and $35^{\circ}C$ and $65^{\circ}C$ of extraction temperature.

  • The effects of various enzymes and emulsifiers on the loaf volume and crumb hardness of rice breads were studied. Four different enzymes [fungal ${\alpha}$-amylase (AMYL), maltogenic bacterial ${\alpha}$-amylase (NMYL), glucose oxidases (GO), and xylanase+hemicellulases (PTP)] and four emulsifiers [sorbitan monostearate (SMS), glycerol monostearate (GMS), sodium stearoyl lactylate (SSL), and glycerol ester+propylene glycol ester+sucrose ester+sorbitan ester (SP)] were supplemented to rice dough. The addition of AMYL, GO, and GO+AMYL increased loaf volume of rice breads. The highest loaf volume was observed in rice bread supplemented with AMYL. Rice breads supplemented with enzymes firmed at lower rates during storage, and AMYL, NMYL, and GO considerably decreased crumb hardness of rice breads, exhibiting a significant antistaling effect. The addition of emulsifiers produced rice breads with better specific loaf volume and crumb texture, and continuously retarded crumb hardness of rice breads during storage. Especially, rice bread supplemented with SSL demonstrated the highest loaf volume and the lowest crumb hardness during storage.

  • To enable effective notification and promotion of the food poisoning prevention, Ministry of Food and Drug Safety (MFDS) developed a mobile augmented reality (AR) game called 'Sik-Jung-Dok-Jop GO', and demonstrated the game at 11 events including Food Safety Day. At the events, we have conducted a field survey of people who have played the game, and evaluated the awareness change of the food poisoning before and after the game. The level of the respondents' awareness about the 3 methods of the food poisoning prevention has been increased by 53 percent after playing the game, the level of awareness about individual food poisoning micro-organism has been improved by 2.1 times. According to the survey, 95% at the respondents answered that the game helped them understand the food poisoning more, and 90% of the respondents said that they enjoyed the game. In conclusion, we believe that 'Sik-Jung-Dok-Jop GO' will be able to create various educative effects on prevention of food poisoning including causative foods, main symptoms, and other related knowledge when the game is widely applied to students in kindergartens, elementary, middle, and high schools.

  • Film-forming yeasts generate an undesirable yeasty flavor in fermented vegetables such as kimchi in the presence of oxygen. Antimicrobial materials including garlic oil (GO), heated garlic (HG), and allyl alcohol (AA) were investigated for use as alternative natural food preservatives to inhibit the growth of film-forming yeasts in fermented vegetables. Using the fermentation of cucumber pickles as a model system, GO, HG, and AA were effective in preventing film formation at concentrations of 0.006, 3.0, and 0.02%, respectively. The effectiveness of HG in preventing the growth of a film yeast, Hansenula anomala, was not influenced by pH, while that of potassium sorbate, a typical anti-yeast food preservative, was highly dependent on pH. All tested materials were effective when added at the beginning of fermentation due to their negligible inhibitory activity toward lactic acid bacteria.
