  • Objective: Marbling or intramuscular fat (IMF) has been widely reported to directly impact the sensory acceptance of meat. This study was carried out to determine the physical and sensory characteristics of ribeye, Longissimus dorsi steaks obtained from four different cattle breeds namely Wagyu, Angus, Brahman, and Malaysian local beef, the Kedah-Kelantan (KK). Methods: The degree of marbling was determined by using an established combined camera-image analysis technique while instrumental texture determination was carried out by using Warner-Bratzler shear force analysis. Sensory evaluation of the beef steaks was performed following a quantitative descriptive analysis incorporating 10 trained consumer panelists. Results: Wagyu was found to possess the highest (p<0.05) percentage of IMF at 33.90% and the lowest shear force (raw = 5.61 N/㎟; cooked = 14.72 N/㎟) followed by Angus (20.87%), Brahman (12.17%), and KK (p<0.05, 6.86%). The difference in sensory properties of the four steaks was evident, with Wagyu appearing to be highly correlated with most sensory attributes measured namely sustained buttery, tooth-packing, chewiness, juiciness, tenderness, mouthfeel, oiliness, and overall acceptability. The Malaysian local beef, KK was found to be less acceptable (p<0.05), although most of its sensory attributes were found similar (p>0.05) in appearance, aroma, texture, juiciness, and flavour to the cooked steak from Angus and Brahman. Conclusion: This present study demonstrated the role of IMF in determining the quality and sensory acceptance of beef from different cattle breeds. These data have provided new information and further understanding on the physical and sensory quality of Malaysian local beef.

  • The purpose of this study was to develop a cooking method for skate pipyun made from skate skin and water. As the gel formation conditions, several skin contents (30~60%) and cooking times (10, 14, and 18 min) were determined. Test for quality characteristics of pipyuns was carried out by measuring texture, water content and pH, sensory evaluation, and heat stability of pipyun gel: five samples (S2: 40%, 10 min, S3: 50%, 10 min, S6: 40%, 14 min, S9: 30%, 18 min, S10: 40%, 18 min) with appropriate gel texture were selected based on their hardness, adhesiveness, and springiness. There was no difference in color among the five pipyuns. Hardness, chewiness, and gumminess of pipyuns significantly increased depending on skate skin content and cooking time. Water contents were significantly higher in S2 (83.40%) and S6 (82.97%). The pH levels of pipyuns appeared to be weakly alkali in the range of 8.17~8.71. In the sensory evaluation, S2 was the most preferred overall with significantly higher evaluation of transparence, gloss, and smoothness. The stability of gels S2 and S9 decreased during storage at $10^{\circ}C$ for 8 hours, and at $20^{\circ}C$ for 60 min. Therefore, heating a mixture of 40% skate skin with 60% water for 10 min is recommended as optimum conditions for producing skate pipyun.

  • We examined the quality characteristics and texture of Jokpyuns with chicken and codfish. In proportion to the increase of water addition, the color became lighter and the texture characteristics decreased in So-Jokpyuns, which were prepared with cow feet. The texture and taste had an influence on overall preference of So-Jokpyun. Yongbon-Jokpyun which was prepared with cow feet and chicken was much preferred to So-Jokpyun in the appearance and texture, and showed a similar preference with So-Jokpyun. However, Sodaegu-Jokpyun which was prepared with cow feet and codfish was not preferred to So-Jokpyun in all items including appearance and texture, and the overall preference was remarkably low. Overall preference of Yongbong-Jokpyun and Sodaegu-Jokpyun was greatly related with the preference of taste and flavor. The lightness and the degree of yellow color of Yongbong-Jokpyun were higher and the degree of red color was lower than So-Jokpyun. On the other hand, the results of lightness, degree of red and yellow color in Sodaegu-Jokpyun were opposite to those of Yonsbong-Jokpyun. In case of the hardness, Yongbong-Jokpyun was the lowest and Sodaegu-Jokpyun was similar with So-Jokpyun. Adhesiveness of Yongbong-Jokpyun and Sodaesu-Jokryun was lower than that of So-Jokpyun. There was no difference in the springiness and cohesiveness among 3 kinds of Jokpyun.

  • The quality characteristics of bread prepared with the addition of dried persimmon peel powder(PPP) were investigated. Visco-elastic characteristics of dough and texture of bread added PPP was examined by rapid visco-analyzer and texture analyzer. The maximum viscosity of the dough with PPP was lower than that of control at 90$\^{C}$. Final viscosity after cooling to 50$\^{C}$, viscosity of control increased to 134 B.U., but that of the dough with PPP showed 13∼37 B.U. As more PPP was added, gluten formation and mixing time dough were longer. Adhesiveness, springness, cohesiveness and chewiness gradually increased as PPP content increased, while the hardness decreased. Lightness value decreased but redness and yellowness values increased with the addition of PPP, especially, the bread made by 15% PPP treatment showed dark brown color. In sensory evaluation of bread, score of color decreased significantly as more PPP was added but overall acceptability was not significant different(p<0.05) between control and 5% PPP treatment. It is considered that the addition of 5% was appropriate for bread making with PPP.
