  • The sensory characteristics of cream soup containing 0, 25, 50, 75 and 100% rice flour were investigated in order to develop a new processed food using rice. The Hunter L(lightness) value increased with the amount of rice flour, while the a(redness) value and b(yellowness) value decreased, significantly. The viscosity of rice cream soup significantly decreased with the increasing amount of rice flour. Based on the sensory evaluation, the cream soup samples with larger rice flour component showed a higher clean taste score, while those with the least rice flour resulted in higher darkness, viscosity, greasy taste, md softness. The overall acceptance was the highest in the cream soup with 75% and 100% rice flour. In terms of the color and viscosity, good correlations were observed between the sensory evaluation and the objective analysis. The overall acceptance showed a significant positive correlation with a clean taste, while there was a negative correlation with a greasy taste and the viscosity measured by a viscometer.

  • The purpose of this study was to evaluate sensory characteristics, and to investigate nutrients and taste compounds in sauce made with shrimp or crab. Shrimp sauce fumed out to have better appearance, color, flavor and texture, and the taste of crab sauce was more excellent. In three kinds of shrimp sauces made with different thickeners, sauces used with rice and roux were evaluated to have a good taste and flavor. The major amino acids were -aminobutyric acid, alanine, ${\alpha}$-aminoadipic acid and citruline in shrimp sauce, and taurine, alanine, ${\alpha}$-aminoadipic acid and citruline in crab sauce. The major fatty acids of both samples were palmitic acid and oleic acid, and also palmitoleic acid and linoleic acid were much detected in shrimp and crab sauce. The content of crude protein was 1.62∼2.44%, and that of crude lipid was 0.92∼1.52% in the two sauces. The major minerals were potassium and sodium in shrimp and crab sauce.

  • This study aimed to reduce the oily taste of Bechamel sauce, and improve consumers' acceptability and functionality by adding Ginseng seed inside. This study also performed quantitative description analysis and acceptability test in order to see its unique sensory characteristics. The results were as follows: The viscosity and moisture content decreased as ginseng seeds got added. This may be due to decrease in relative amount of flour. In terms of color, brightness (L) and yellowness (b) tended to decrease as ginseng seeds were added, while redness (a) showed just the opposite propensity. The salinity became higher with more ginseng seed, however, soluble solid content showed no significant difference among the samples. From the result of quantitative and descriptive analysis among the sensory tests, the concentration of Bechamel sauce got higher with more ginseng seed, where the fragrance and the taste of ginseng were sensed strongly, while fragrance of milk, flour, and nuts were considered weak. Also, sense of stuffiness, oiliness, and tenderness has decreased as well. From the acceptability test, adding 30% of ginseng seed got the highest ratings in terms of fragrance, taste, afterward-taste, and overall acceptability. Therefore, adding ginseng seed positively affected Bechamel sauce in taste, smell, after-taste, and general acceptability. Moreover, when the added amount of ginseng seed was 30% compared to the flour, the taste of Bechamel sauce was relatively optimized. From the test results, it can be concluded that ginseng seed injected in Bechamel sauce improved nutritive facts and the taste acceptability as well, and 30% compared to the flour amount was the right amount to maximize consumers' acceptance of Bechamel sauce.

  • This study was designed to measure taste sensitivity and the five basic senses by an educational classification instrument. The instrument was a rice kit that could use samples in a dry powder form or oil extract after long-term storage To test for taste, sucrose, salt, citric acid, and quinine sulfate were made at different concentrations and taste sensitivity was measured on a scale from level 1 to level 5. To obtain baseline data, an inspection tool for the five senses was used and randomly applied on 101 schoolchildren in the third and fourth grade in the city of Cheonan in Korea. The inspection tool was composed of 17 questions; 5 questions regarding visual characteristics and three questions each for characteristics regarding taste, hearing, smell, and touch. The average age of the schoolchildren was 9.5 years old and there were 49 third grade students (9 years of age), and 52 fourth grade students (ten years of age). There were slightly more male students than female students, 56 (55.4%) compared to 45 (44.6%), respectively. The average height of female students was higher than that of males, but the average BMI (body mass index) of the male students was slightly higher than that of female students (18.28 compared to 18.09, respectively). Female students were slightly more sensitive to salty tastes than male students (2.8 compared to 2.5, respectively). In the score distribution for each sense, touch sense was the highest at 7.59, sight sense was 7.49, hearing sense was 5.43, smell sense was 5.24, and taste sense was lowest at 3.69. Therefore, schoolchildren first tend to recognize and deem important the touch and sight of food before its taste.

  • Purpose: Patients with taste complaints presenting with various abnormal perceptions and alterations in gustatory function are often encountered in dental clinics. Since taste perception is thought to be influenced by numerous factors including neurological and psychological factors, the gustatory profiles of patients complaining of taste abnormalities should be very different. However, the gustatory profiles based on the clinical subtypes of taste complaints have not been fully studied. This study aimed to better understand the gustatory profiles depending on the clinical subtypes of taste complaints. Methods: Clinical data from 169 patients with complaints of altered taste were retrospectively collected to analyse their clinical and gustatory profiles. These complaints were subdivided into hypergeusia, hypogeusia, and dysgeusia for each taste quality according to the clinical types of these complaints. The gustatory profiles were then established by analysing the detection and recognition thresholds for each taste quality depending on the clinical subtypes of taste complaints. Results: Clinical analysis revealed that patients with taste complaints had widely diverse clinical profiles. There were significant differences between males and females with taste complaints in the prevalence rates of symptoms like dry mouth, tongue coating, and burning sensation. While hypogeusia (76.3%) was the most frequent type of taste complaint, it was revealed that the taste thresholds were not always consistent with the patient's description of gustatory symptoms. Conclusions: Patients with taste complaints exhibited diverse clinical profiles with sex differences. Considering the diversity of the taste complaints, the quantitative gustatory testing methods can be valuable to differentially evaluate the presence and intensity of altered taste in patients with these complaints.

  • This study investigated the amino acid and nucleotide-related compound composition and taste characteristics of cultured muscle tissue (CMT) obtained by culturing satellite cells isolated from chicken and cattle and compared them to those of traditional meat (TM). The content of all amino acids except valine and tyrosine was significantly different between CMT and TM (p<0.05). The amount of glutamic acid was not significantly different between CMT and TM in cattle, but the glutamic acid in chicken CMT was lower than that of TM (p<0.05). Among the nucleotide-related compounds, only the content of inosine-5'-monophosphate (IMP) was significant, and the amount of IMP in CMT derived from chicken and cattle was significantly lower than that of TM (p<0.05). There were significant differences in the taste characteristics assessed by an electronic tongue system, and the umami, bitterness, and sourness values of CMT were significantly lower than those of TM from both chicken and cattle (p<0.05). The results of the present study suggest that it is necessary to develop a satellite cell culture method that could increase the umami and bitterness intensity of CMT and adjust the composition of the growth medium to produce cultured meat with a taste similar to that of TM.

  • To develop customized food products for gastric cancer patients, it is crucial to understand their dietary characteristics and changes in their perception of smell and taste due to their condition. This study conducted in-depth interviews and administered olfactory and gustatory tests on 20 patients with gastric cancer. A control group of 20 healthy, gender and age matched individuals, was included for comparison. Patients reported difficulties in sustaining their appetite, particularly during chemotherapy. This could be attributed to gastrointestinal discomfort and an altered perception of smell and taste. The olfactory test revealed that cancer patients were significantly less sensitive than the control group. Also, a smaller number of participants in the cancer group were reported to have a normal taste function, which enabled them to perceive umami, one of the five basic taste compared to those in the control group. These findings demonstrated that gastric cancer patients experience post-surgical digestive issues, chemotherapy-induced changes in smell and taste, and appetite loss. To improve the quality of life of these patients and the efficacy of the treatment, it is necessary to consider not only their nutritional requirements but also other factors such as appetite loss and discomfort when developing meals specifically for them.

  • This study was conducted to evaluate the mechanical (texture and color) and sensory characteristics of mulberry leaf sulgi (MLS) and lotus leaf sulgi (LLS) that contained different ratios of ingredients. MLS and LLS with final concentrations of 0%, 1%, 3% and 5% of powdered mulberry and lotus leaf respectively, were prepared. The texture characteristics (hardness, adhesiveness, springiness, cohesiveness, gumminess, chewiness), color values (lightness, redness, yellowness), and sensory characteristics (color, flavor, moistness, taste, brittleness, chewiness and after-taste) of the different sulgis were then measured and compared. With the exception of gumminess and chewiness, the texture characteristics of 0% MLS, 1% MLS and 3% MLS were not significantly different. The sensory characteristics of 0% MLS had the highest scores, whereas those of 5% MLS were the lowest for all factors except for brittleness. However, with the exception of chewiness, the scores obtained from 0% and 1 % MLS did not differ significantly. In addition, 1% MLS and 3% MLS were not significantly different from each other. Furthermore, the texture characteristics of 0% LLS and 1 % LLS were not different significantly, although the characteristics of 1% LLS were significantly different from those of 3% and 5% LLS when springiness, cohesiveness, and chewiness were considered. Additionally, the sensory characteristics of 0% LLS and 1% LLS were not significantly different, with the exception of brittleness, and the characteristics of 1% LLS and 3% LLS were not significantly different, with the exception of taste and after-taste.
