Rice dumpling shells were prepared with different levels of hydrocolloids, such as hydroxypropyl methyl cellulose (HPMC), and potato starch. After steaming, the physical, sensory, and cooking properties of the shells were measured. Increasing the amount of potato starch decreased the pasting temperature and increased the peak viscosity. With the addition of hydrocolloids, water absorption and cooking loss for the rice dumpling shells decreased significantly. For the textural properties, the rice dumpling shells with hydrocolloids showed lower hardness and higher springiness than the control, and especially, 10% potato starch and 3% HPMC addition (P10H3) improved the texture of the rice dumpling shells the most. The sensory results seemed to be affected more by the addition of potato starch than HPMC, and over 15% addition of potato starch significantly decreased the quality of the rice dumpling shells. By addition of adequate amount of hydrocolloids (3% HPMC and 10% potato starch), the sensory quality of rice dumpling shells can be effectively improved.

The purpose of this study was to compare the physicochemical properties of sausage manufactured with carp (Carassius carassius) muscle and pork. Sausages were prepared using either 100% pork sausage (P10), a mixture of 50% pork and 50% carp muscle (P5C5), or 100% carp muscle (C10). The quality of the sausage emulsion was determined by analyzing approximate composition, pH, instrumental color, cooking yield, water holding capacity (WHC), viscosity, and texture profile analysis (TPA). Moisture content of cooked C10 was significantly higher than that of P10 or P5C5 (p < 0.05); however, protein content of cooked P10 was significantly higher than that of C10 (p < 0.05). The pH of uncooked and cooked C10 was significantly higher than that of P10 and P5C5 (p < 0.05). The cooking yield, WHC, and texture profile analysis of C10 were higher than those of P10 and P5C5 (p < 0.05). In addition, the viscosity of uncooked C10 was higher than that of P10 and P5C5. These results suggest that carp muscle can enhance sausage quality with respect to pH, WHC, cooking yield, viscosity, and TPA.

In this study, a survey was conducted to both evaluate the consumers' general attitudes for purchasing and storing the raw chicken and determine the thawing practices used for defrosting frozen chicken at home. About 75% of the consumers indicated purchasing chicken meat at least once a week or more. Furthermore, the majority (82.16%) of those who stored at least a portion of the raw chicken stated freezing the raw chicken meat at home. Freezing the chicken meat was considered to have no effect on the quality by 43.49% of the consumers while 56.51% thought that freezing had either negative or positive effects on the quality. The survey study indicated that top five most commonly used thawing practices included thawing on the kitchen counter, thawing in the refrigerator, thawing in the warm water, thawing in the microwave, and thawing under tap water. In addition, an experimental study was conducted to determine the effects of these most commonly used thawing practices on some quality characteristics of the chicken meat including pH, drip loss, cooking loss, color analysis and textural profile analysis. Although, $L^*$ value for thawing on the kitchen counter was the lowest, after cooking, none of the thawing treatments have a significant effect on the color values. Thawing in the microwave produced the highest drip loss of 3.47% while the lowest drip loss of 0.62% was observed with thawing in the refrigerator. On the other hand, thawing in the microwave and refrigerator caused the lowest cooking loss values of 18.29% and 18.53%, respectively. Nevertheless, there were no significant differences among textural parameter values of the defrosted and then cooked samples using the home based thawing practices, indicating similar quality characteristics among the samples.
