  • The purpose of this study was to develop a standardized recipe of Hwajeun(glutinous rice pancake with flower) by evaluating various methods appeared in the literature. For this purpose, the effects of the volume and temperature of water used to make dough on the sensory and rheological characteristics of Hwajeun were investigated. This experiment consisted of sensory evaluation in acceptance and intensity(appearance, color, moistness, softness, chewiness, adhesiveness, taste and overall preference), objective evaluation by using texture analyser, color difference meter and measurement of water content and oil absorption ratio. The loss ratio of moisture contents between dough and cooked Hwajeun were 2.4 ~2.8%, and the oil absorption ratio of Hwajeun made by 2$0^{\circ}C$water for kneading increased in proportion to the increment of water added(p<0.01). In terms of color, b value of Hwajeun made by 104$^{\circ}C$ salted water for kneading showed higher value compared to the others. In the two bite compression test, adhesiveness, springiness, gumminess and chewiness of Hwajeun made by 2$0^{\circ}C$ water(36%) for kneading showed significantly(p<0.05) high value among the samples. As a result of sensory evaluation, Hwajeun made with 27% of 104$^{\circ}C$ salted water for kneading was most preferred in softness, chewiness, taste and overall preference

  • The purpose of this study was to standardize the various methods and recipes of Hwajeun (glutinous rice pancake with flower) that appeare in the literature. For this purpose, the effects on sensory and physical characteristics of Hwajeun in various kinds of dipping syrups (S1 : honey, S2 : rice syrup, S3 : com syrup, S4 : sugar syrup and S5 : sugar) during storage for 24hrs were investigated. This experiment consisted of the measurement of water content, color difference meter, texture analyser and sensory evaluation for acceptance (color, flavor, moistness, softness, chewiness, adhesiveness, sweetness and overall acceptability). The moisture contents decreased with increasing storage time, indicating that S1 had a significantly (p<0.01) high value until 12hrs. The colorimetric values of lightness (L), redness (a) and yellowness (b) decreased and the total color difference values ($\Delta$E) increased with increasing storage time. In the two bite compression test, the hardness of S1 and S3 showed significantly (p<0.0001) lower values than other samples. As a result of the sensory evaluation for Hwajeun prepared with various kinds of dipping syrup, S1 and S3 were most preferred in color, flavor, moistness, chewiness, adhesiveness, sweetness and overall acceptability of sensory evaluation.

  • The aim of this study was to standardize the various methods and recipes of Hwajeun (glutinous rice pancake with flower) appeared in the literature. For this purpose, the effects on the sensory and rheological characteristics of Hwajeun in terms of the various levels of oil and frying times were investigated. This experiment consisted of a sensory evaluation in terms of the acceptance (color, flavor, oily feeling, softness, chewiness, adhesiveness, taste and overall preference) and objective evaluation performed by a texture analyzer, a color difference meter and measurements of the water content and oil absorption. The moisture content of the treatments as a function of the frying time, S7, showed a significantly(p<0.01) low value, and the oil absorption of the Hwajeun made with different frying times increased in proportion to the increment of the frying time(p<0.001). In terms of color, the b value of the Hwajeun made with 16g oil for frying showed a higher value than the others. In the two bite compression test, the hardness of the Hwajeun made with 4g oil for frying showed a significantly (p<0.001) high value among the S2 and S3 samples. As a result of the sensory evaluation for the Hwajeun made with various amounts of oil and frying times, the Hwajeun made with 16g oil for frying and a 2 min frying time for each side (S6) was the most preferred in terms of the softness, chewiness, taste and overall preference of the sensory evaluation
