We present a case report of a 52-year-old male patient who suffered head trauma in a car accident and subsequently experienced taste and smell disorders. Following the accident, the patient reported difficulty detecting salty and sour tastes and diminished olfactory perception. Neurosurgical evaluation revealed subarachnoid and subdural hemorrhages, while otolaryngology investigations revealed hyposmia-a decreased sense of smell. Upon referral to the Department of Oral Medicine, a comprehensive assessment revealed a general bilateral reduction in taste sensation, particularly ageusia for salty taste. Electric taste-detection thresholds significantly exceeded the normal ranges. Integrating our findings from neurosurgery, otolaryngology, and oral medicine resulted in a diagnosis of mixed chemosensory disorder attributed to head trauma. This case highlights the intricate interplay of alterations in taste and smell following head injury, emphasizing the significance of multidisciplinary evaluations in diagnosing mixed chemosensory disorders resulting from traumatic brain injury.

The addition of green tea to kimchi making for extanding the optimum edible period was studied. The equality and sensory characteristics of green tea added kimchi were evaluated. The acidity, lactic acid and acetic acid contents of green tea added kimchi showed lower than that of control kimchi but reducing sugar and vitamin C contents was higher. The duration of optimum edible periods of green tea added kimchi lasted two more weeks. While the optimum pH of kimchi for eating lasted, the sensory pannel score for sour taste of green tea added kimchi was lower than that of control but the scores for overall quality and hardness were higher. Especially, the sour taste score between two groups were significantly different(p<0.05). There was no differences in texture determined by Penetrometer between green tea added kimchi and control kimchi until the fermentation reached the optimal condition for eating. After that period, the degree of degradation of texture was much delayed in green tea added kimchi.

This study was carried out to establish the optimal conditions for curd yogurt using saccharified rice solution. A central composite design was applied to investigate the effects of pectin (2.8~8.4 g), skim milk (14~70 g) and oligosaccharide (28~84 g) ratio on the physicochemical and sensory characteristics of curd yogurt using saccharified rice solution. pH, total acidity, and color value, were analyzed and sensory evaluation was performed. The pH of curd yogurt decreased with decreasing pectin and oligosaccharide ratio. The addition of pectin had a significant effect on the viscosity while skim milk had a significant effect on the color value (a and b value). The results of sensory evaluation showed that, oligosaccharide and skim milk had significant effects on sweetness and sour taste. Oligosaccharide and skim milk masked the sour taste of curd yogurt. The optimum range of ingredients for curd yogurt using saccharified rice solution was predicted to be 4.27~4.90 g of pectin, 30.80~41.30 g of skim milk, and 28.00~36.10 g of oligosaccharide. Based on the overlapped results of physicochemical and sensory evaluation, the optimal amounts of pectin, skim milk and oligosaccharide were 4.59 g, 36.50 g and 32.05 g, respectively.

This study evaluated the sensory characteristics of sauerkraut prepared by adding 0.5, 1.0, 1.5, 2.0, and 2.5% (w/w) sea salt to cabbage. The quantitative descriptive analysis (QDA) and acceptance test of sauerkraut were determined for each salt concentration, and the principal component analysis (PCA) and partial least square regression (PLSR) analysis were performed to confirm the correlation between each factor. Results of the QDA determined 14 descriptive terms; furthermore, brightness and yellowness of appearance and the sour, salty, and bitter flavors differed significantly according to the salt concentration. Results from the PCA explained 22.56% PC1 and 65.34% PC2 of the total variation obtained. Sauerkraut prepared using 0.5, 1.0, and 1.5% sea salt had high brightness, moistness, sour odor, green odor, sour flavor, carbonation, hardness, chewiness, and crispness, whereas sauerkraut prepared with 2.0 and 2.5% sea salt had high yellowness, glossiness, salty flavor, sweet flavor, and bitter flavor. Hierarchical cluster analysis classified the products into two clusters: sauerkraut of 0.5, 1.0, and 1.5%, and sauerkraut of 2.0 and 2.5%. Results of PLSR determined that sauerkraut of 1.0 and 1.5% were the closest to texture, taste, and overall acceptance. We, therefore, conclude that sauerkrauts prepared using 1.0 and 1.5% sea salt have excellent characteristics in appearance, taste, and texture.

The purpose of this study is to investigate the sensory characteristics of Toha-jeot added cabbage kimchi by Koreans and Japanese. The sensory evaluation was conducted for the following 9 items such as color, savory taste, carbonated taste, sour taste, hot taste, salty taste, off flavor, texture and overall preference. Sensory evaluation of kimchi was tested by Koreans or Japanese whose ages vary from 30 to 50 years old and each group had 25~30 evaluators. Kimchi at different stages of fermentation day 0, 10 and 18th was evaluated. Saltiness of kimchi was 1.5~2.1% through the fermentation period and pH of kimchis was decreased from pH 5.4~5.6 to 4.3~4.4 during the fermentation. The sensory evaluation of Toha-jeot added cabbage kimchi by Koran and Japanese showed the differences in evaluation as the fermentation proceeded. The color, texture and overall preference of Toha-jeot added cabbage kimchi fermentation for 10th days was scored significantly high by Korean group while the score for the savory taste was increased as the fermentation proceeded. The hot taste preference of Toha-jeot added cabbage kimchi fermented 18th days scored significantly high and also increased as the fermentation proceeded by Japanese group. The overall preference of Toha-jeot added cabbage kimchi by Japanese group was higher than that of control cabbage kimchi tested at 10 and 18th days fermentation.

오디청 제조 시 부족한 산미를 높일 수 있는 부재료로 오미자를 이용하기 위하여 오미자 첨가율에 따른 품질 특성을 살펴보았다. 오미자 총산 함량은 오디의 20배인 5.71%로, 적절한 첨가율과 추출기간에 오디청의 산미를 증가시킬 수 있었다. pH와 총산은 추출 초기에 첨가율별 큰 차이를 나타냈으며, 첨가율 증가에 따라 pH는 감소하였고 총산은 증가하는 경향을 나타냈다. 당도와 pH, 안토시아닌과 총산은 추출기간에 따라 상반된 경향을 보였으나 10일 이후에는 모두 큰 변화를 나타내지 않았다. 가공식품 개발 시 가장 중요한 맛의 기호도 평가에서 OC-3과 OC-4는 $4.20{\pm}0.75$와 $4.05{\pm}0.80$을 나타내어 오미자가 첨가되지 않은 control $2.30{\pm}1.24$와 비교하여 매우 높은 수준을 나타냈다(P<0.05). 이것은 오디청 제조 시 오미자를 이용하여 소비자의 기호도가 향상된 결과였다. 음료용 오디청 제조 시 오미자를 이용하여 신맛을 강화시키기 위한 조건은 여러 품질 특성을 고려하여 18.75~25%의 오미자를 첨가하고 10~12일 정도에 추출하는 것이 가장 바람직할 것으로 생각된다.

This dissertation aims to study the five tastes in the Yellow Emperor's Canon of Internal Medicine. Medicinals as well as Foods are classified by the five tastes: sweet, sour, bitter, salty and pungent, which can be tasted by the tongue. With the development of the theory dealing with the medicinal properties, some flavors are summarized out of clinical actions of medicinals, therefore, there is a little difference between the flavors of medicinal herbs and the tastes got by tongue. Each taste acts on or has direct influence on a specific vital organ, and each of which has different physiologic actions. Taste also has a long-term or post digestive effect on the body and its metabolism. When each taste is consumed in moderation, it benefits the corresponding organ. Over-indulgence in any taste harms the organ and creates imbalance among the five vital organ systems. The Korean medicinal herbs with same flavor mostly possess similar actions while the medicinal herbs with different flavors show different actions in the treatment, which are shown as follows. Sour has absorbing, consolidating and astringent actions and acts on the liver. Bitter has the actions of drying or resolving dampness, purging and lowering and acts on the heart. Sweet has the nourishing, harmonizing and moistening actions and acts on the spleen. Pungent has an action of dispersing and promoting circulation of gi and blood and acts on the lungs. Salty has the effects of softening hard nodes or masses and promoting defecation, etc and acts on the kidneys. The five organ systems control and support each other. Proper coordination only exists when there is no one organ stronger or weaker than the rest. Since the five tastes have direct influences on the five organs, the diet we take should have a good combination of the five tastes in order to promote internal balance and harmony. They control our well-being and create dietary balance. Excessive consumption of any of these could result in adverse effects. In a word, when the properties of the five tastes respectively are distinguished, their natures and flavors cannot be separately considered. I think the harmonization of food and medicinals should be stressed on good nutritional diet to maintain good health. The traditional belief that food and medicine share the same origin is a part of Korean medicine tradition.

본 연구에서는 선행 발효두유에서의 산미 이취를 개선시키기 위해 한국 전통발효식품인 김치로부터 젖산균을 분리 및 동정하였다. 분리된 89주의 균주 중 두유 발효 시 산미 이취를 생성하지 않는 균 3주(Strain No. R53, R83, R84)를 임의로 분리하였다. 생물학적, 형태학적 및 16S rRNA 유전자 염기서열 등과 같은 생화학적 분석 결과 최종적으로 3주의 균은 W. koreensis 동정되었다. 최종적으로 이 3주의 균 중 가장 산미 이취를 적게 생성하는 것으로 판단되는 Strain No. R83을 최종 실험 균주로 사용하였으며 이 균주를 W. koreensis KO3로 명명하였다. W. koreensis KO3을 이용하여 최적 발효두유를 제조하였으며 이화학적 특성을 알아보았다. $30^{\circ}C$에서 12시간 발효시켰을 때 생균수가 $8.71{\times}10^8CFU/ml$로 가장 생육이 뛰어났으며, 이때의 pH와 산도는 각각 6.02, 0.33%를 나타내었다. 일반성분은 수분 94.06%, 조회분 0.18%, 조단백 2.71%, 조지방 1.16%, 조섬유 0.01%로 측정되었다. 아미노산 분석 결과 27종의 아미노산과 유도체들이 확인되었다. 단맛을 가지는 아미노산으로 알려진 serine, glycine, threonine, alanine, aspartic acid 함량이 증가하였고 발효 전에는 검출되지 않았던 ornithine이 생성되었다. 관능평가에 있어서는 선행 발효두유에 비해 모든 항목에서 개선된 평가를 얻었다. 따라서 관능검사, pH 및 산도 그리고 아미노산 분석을 결과를 토대로 볼 때 W. korensis K03로 제조한 발효두유는 음료로서 가능성이 있다고 생각되며 향후 연구를 통해 기능성 성분이 탐색 된다면 새로운 형태의 건강식품개발의 기초 자료로서 활용 가능할 것으로 보인다.
