This study determined the effects of soybean oil$2\%$) and chitosan($1\%$) on the quality characteristics of Omija Jelly made of various starches (mungbean starch, cowpea starch and corn starch). RVA(Rapid Visco Analyzer) viscosity was measured for starches suspended in Omija aextract with $2\%$ soybean oil and $1\%$ chitosan. The color value, syneresis, texture(rupture test and TPA test) and sensory properties of the samples were measured. Gelatinization of cowpea starch was expedited by adding soybean oil and chitosan. Otherwise, gelatinization of mungbean starch and com starch was retarded by adding chitosan. The lightness(L) and the syneresis of Omija Jelly with soybean oil and chitosan were decreased, indicating the increased transparency and stability of Omija Jelly. Rupture stress and rupture energy of Omija Jelly were decreased by adding soybean oil. Rupture stress was increased and rupture energy was decreased by adding chitosan. The addition of soybean oil improved texture of Omija Jelly, indicating that the springiness, cohesiveness and chewiness of Omija Jelly were increased and adhesiveness was decreased. By adding chitosan, the springiness and hardness of Omija Jelly were increased and the cohesiveness and adhesiveness were decreased. The overall acceptability of Omija Jelly made of $6%$ or $7\%$ cowpea starch and com starch was increased by adding soybean oil and chitosan, but the quality characteristics of Omija Jelly made of mungbean starch were not influenced by additives such as soybean oil and chitosan.

Wheat (Triticum aestivum L.) grain texture is an important determinant of milling properties and end product use. Two linked genes, puroindoline a (PINA) and puroindoline b (PINB), control most of the genetic variation in wheat grain texture. Wheat seed proteins were examined to identify PINA and PINB gene using two pre-harvest sprouting wheat cultivars; Jinpum (resistant) and Keumgang (susceptible).Wheat seed proteins were separated by two-dimensional electrophoresis with IEF gels over pH ranges: pH 3-10. A total of 73 spots were digested with trypsin resulting peptide fragmentation were analyzed by matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF/MS). Mass spectra were automatically processed and searched through NCBInr, SWISS-PORT and MSDB database with mono isotopic masses and complete gene sequence were found by UniProt database. Puroindoline a and puroindoline b that is responsible for grain texture related with baking performance and roughness. Two spots were found Pin b (16.7 kDa) and Pin a (16.3 kDa) in Jinpum compare to seven spots were identified Pin a (16.1 kDa, 16.3 kDa) and Pin b (16.7 kDa, 9.5 kDa and 14.4 kDa) in Keumgang. Some selected spots were identified puroindoline like grain softness protein (16.9 kDa, 17 kDa and 18.1 kDa) in Keumgang. Moreover, to gain a better inferring the identification of puroindoline related proteins using proteomics, we accomplished a complete gene sequence of PINA and PINB gene in pre-harvesting sprouting wheat seeds between resistant (Jinpum) and susceptible (Keumgang).

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 objective of this study was to evaluate physicochemical and sensory properties, the texture profile, and antioxidant activity of ginseng extract-supplemented quark cheese as a new cheese product intended to improve public health. After addition of less than 1.0% ginseng extract, the moisture content of quark significantly decreased, while fat and protein levels increased, although microbial counts and lactose and ash contents were not affected significantly (p<0.05). In terms of color, $L^*$ values decreased significantly with increasing concentration of ginseng extract, while $a^*$ values increased significantly (p<0.05). The results of texture profiling showed that cohesiveness and springiness were unaffected, whereas hardness, gumminess, and chewiness increased significantly. The 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical-scavenging activities of the cheese fortified with 0%, 0.5%, or 1.0% of the ginseng extract were $4.22%{\pm}0.12%$, $20.14%{\pm}1.34%$, and $56.32%{\pm}1.54%$, respectively. The results of sensory analysis indicated that bitterness, ginseng odor, and aftertaste significantly improved with increasing concentration of ginseng extract (p<0.05). However, there was no significant difference in the overall quality attributes of quark cheese between the no-supplement control and samples with less than 0.5% of the ginseng extract (p>0.05), suggesting that these products could help to promote public health as functional foods.

The objective of this study was to determine the effects of quality grade (QG), and back-fat thickness on the carcass traits and meat quality properties of Hanwoo steers. Fifty carcasses were sorted into two QG (QG 1+ and 1) and three back-fat thickness (<10 mm, 10 to 19 mm and ≥19 mm) groups. After investigating the carcass traits (rib eye, back-fat thickness, weight, color, yield index, maturity, marbling score, and texture), the longissimus lumborum muscles from the carcass groups were collected and analyzed for meat quality (pH, color, cooking loss, and moisture), texture profiles [Warner-Bratzler shear force (WBSF), and tensile tests], and fatty acid. Results showed that marbling score (p<0.001), moisture (p<0.05) and tensile tests values (p<0.05) had a significant differences between QG1+ and QG1. No differences in pH, color traits, cooking loss and WBSF values occurred between the QG groups. Regarding the back-fat thickness effect, we observed that the carcass weight, yield index (p<0.001), yield grade (p<0.001) and marbling score (p<0.05) had a significant differences among the back-fat thickness groups. Regarding the meat quality, moisture content and WBSF values (p<0.01) among the back-fat thickness groups. The back-fat thickness did not affect the pH, color, cooking loss and tensile tests. The QG and back-fat thickness did not affect the fatty acids contents (p>0.05). It may be concluded that the carcass traits and meat quality were significantly affected the QG and back-fat thickness.
