  • Recently, with the sensor technology, research about the electronic nose system which imitated the olfactory organ are being pushed actively. But, in case of general electronic nose system, an aroma is measured at the laboratory space where blocked external environment and is analyzed a part of measured data. In this paper, we propose the system which can measure and recognize an aroma in natural environment. We propose the Entropy algorithm which can detect the sensor reaction section among the continuous detection processing about an aroma. And we implement the aroma recognition system using the PCA(Principal Components Analysis) and K-NN(K-Nearest Neighbor) about the detected aroma. In order to evaluate the performance, we measured the aroma pattern, about 9 aroma oil, 50 times respectively. And we experimented the aroma detection and recognition using this. There was an error of 0.2s in the aroma detection and we get 84.3% recognition rate of the aroma recognition.

  • Aroma oils extracted from the natural material have antibacterial, antivirus, antiinflammatory, and preservative effect. The preserve efficacy testing between aroma oils and parabens as an artificial preservative had been performed and then it had been suggested that aroma oil was possibile to apply to the cosmetics. Aroma oils were pine, rosemary, lemon and eucalyptus, and parabens were methylparaben, blitylparaben. Antiseptic concentrations of aroma oils and parabens having 0.0, 0.1, 0.2, 0.4, 0.8, 1.0wt% were tested respectively. Escherichia coil(ATCC No.8739), Pseudomonas aeruginosa(ATCC No. 9027) which are gram-negative and Staphylococcus aureus (ATCC No. 6538), Bacillus subtilis(ATCC No. 6633) which are gram-positive were used as the test organisms. Disk paper and broth dilution methods were used as the methods of preservative efficacy testing. The antibacterial activity of aroma oils and parabens for gram-positive were better than that for gram-negative. For the antibacterial activity aroma oils were better than parabens. Among the aroma oils, rosemary and pine having superior antibacterial activity were selected and blended to illuminate if there is any synergy, There was synergical effect and optimum ratio of aroma blend is 3 : 1(rosemary pine) in this study.

  • In this study, "Hongro" apples for test samples were selected from a market for aroma analysis. Analysis was done after 1 hr, in a forming headspace while maintaining a temperature of $25^{\circ}C$. First, the complex aroma of the apples was assessed by a Direct Sensory Method. Secondly, the complex aroma was analyzed under individual aroma conditions separated by GC/FID/Olfactometry. Finally, aroma component analysis by GC/MS was performed. Degrees of contribution of aroma components were evaluated by an aroma value calculation considering aroma duration time, frequency, and intensity. The contribution rate (%) of the aroma induction component influencing apple aroma was determined by aroma component analysis and aroma contribution degree. As a result, it was found that the top four components were as follows, by contribution rate (%): acetic acid (23%), 1-hexanol (16%), butyl ethanoate (13%), 4-methoxy-2-methylbutane (9%). These four components constitute the complex aroma tested by the direct sensory method, and was largely recognized by the apple aroma test panel. Consequently, it was found that these components are the key factors in apple aroma. If the mechanism of formation of these components can be found, it could have a significant influence on consumers' acceptance of new varieties of apples.

  • This study compared aroma compositions and sensory aroma attributes of raw and cooked Tenebrio molitor larvae (mealworms). Main sensory aroma attributes of raw mealworms were strong wet-soil-like, and less-intense oily, shrimp-like and sweet-corn-like. Quantitatively, the major aroma components of raw mealworms were hydrocarbons and aldehydes. As cooking proceeded, sweet-corn-like, roasted, and fried-oil-like sensory attributes were increasingly perceived with steaming, roasting, and frying, respectively. Some pyrazines, pyrrolidines, and carbonyls increased or appeared in roasted and fried mealworms. Partial least squares regression also showed differences in raw and cooked mealworms based on aroma components and their sensory attributes. Unlike raw mealworms, steamed mealworms had a relatively strong sweet-corn-like aroma attribute, which was related to 2,4,6-trimethyl-heptane, 2,4-dimethyl-dodecane, and 3,5-dihydroxy-6-methyl-2,3-dihydropyran-4-one. In comparison, roasted and fried mealworms exhibited roasted, shrimp-like, and fried-oil-like aroma attributes, which were associated with intermediates of the Maillard reaction and lipid oxidation, such as pyrazines, alcohols, and aldehydes. This result during thermal reactions was very similar to those of meat and/or seafood. The use of mealworms as a savory-type flavor enhancer can be expected.

Also flavors of herbs are spreaded ki of herbs and have many effects on body. Aroma coming through the nose is recognized by co-operation of five-viscera(五臟), especially heart and lung. The nose and pectoral qi(宗氣) are related with lung. The lung opens into the nose, reflect its physiological and pathological conditions. Pectoral qi(宗氣) is the combination of the essential qi derived from food with the air inhaled, stored in the chest, and serving as the dynamic force of blood circulation, respiration, voice, and bodily movements. Because of the heart-spirit(心神), Heart is the organ can recognize the aroma, although the nose is the first organ of receiving aroma.
