This study was carried out to evaluate the effects of microwave power level on cooking properties of ground pork patties (fat level: 20%). Each patty was cooked from a thawed state to $76.7^{\circ}C$ (center temperature) in a microwave oven with power levels of 40% (360 W), 60% (540 W), 80% (720 W), and 100% (full power, 900 W), respectively. Cooking rate increased with power level, and the non-uniformity also increased with time during cooking. Overheating at the edge of the patties was observed for all power levels, and maximum temperature differences in between the edge position and center position were found in patties cooked at the 900 W power level. Compositional properties, total cooking loss, and drip loss were not affected by power level, although moisture content was lower at the edge than at the center position. As the power level increased, the reduction in patty diameter of cooked patties increased while the reduction in patty thickness decreased. Pork patties cooked at lower power levels (360 W and 540 W) had higher shear force values than those cooked at higher power levels (720 W and 900 W). Few changes were observed in instrumental color values.

This study was carried out to elucidate the relationship between different fat levels (0%, 5%, 10%, 15%, 20%, and 25%) and the quality of ground pork patties cooked to reach an internal temperature of $75^{\circ}C$ in a microwave oven. The relationship between fat level and cooking rate of pork patties cooked by microwave energy was highly significant ($R^2=0.72$), and had a low determination coefficient ($R^2=0.55$). The relationship between fat level and total cooking loss of pork patties cooked by microwave energy was also very significant, with a high correlation coefficient of $R^2=0.89$. The correlation coefficient between fat level and cooking drip loss of patties cooked by microwave energy was 0.92, which was highly significant. Although the correlation coefficient between fat level and evaporation loss had a negative value ($R^2=-0.63$), there was a highly significant relationship between fat level and shear force of pork patties cooked by microwave energy.

Sea mustard paste was prepared by treating wet and dried sea mustard with 0.1M Na2CO3, which mainly aimed to extract alginate from the cell wall of sea mustard. The pastes were added to beef, chicken and pork to manufacture the meat patties. The effects of adding the paste were investigated in terms of sensory properties, texture(hardness)and weight changes after cooking. The sensory attributes such as taste, color, texture and juiciness were generally enhanced by adding the paste. The hardness of cooked patties was significantly decreased, so the paste provided softer texture. The addition of paste also resulted in decreasing the weight loss of meat patties after cooking.

This study investigated the effects of bovine plasma protein (PP) hydrolysates on the antioxidant and quality properties of pork patties during storage. Pork patties were divided into 4 groups: without butylated hydroxytoluene (BHT) and PP hydrolysates (control), 0.02% BHT (T1), 1% PP hydrolysates (T2), and 2% PP hydrolysates (T3). Pork patty supplemented with PP hydrolysates had higher pH values and lower weight loss during cooking than the control patties. Results showed that lightness and hardness both decreased upon the addition of PP hydrolysates. All samples containing BHT and PP hydrolysates had reduced TBARS and peroxide values during storage. In particular, 2% PP hydrolysates were more effective in delaying lipid oxidation than were the other treatments. It was concluded that treatment with 2% PP hydrolysates can enhance the acceptance of pork patty.

This study evaluated the quality and antioxidant activities of pork patties after adding Cirsium nipponicum powder in a ratio of 0%, 1%, 2%, 3%, and 4%, and the potential of Cirsium nipponicum as a functional food. The moisture content increased with an increase in the Cirsium nipponicum powder content while the pH, cooking loss rate, diameter loss rate decreased. The L and b values decreased with increase in the Cirsium nipponicum powder content while the a value increased; this trend was observed before and after heating the patties. The hardness, chewiness, and gumminess increased with increase in the Cirsium nipponicum powder content. Consumer acceptability test revealed that the 2% Cirsium nipponicum powder group had a higher score than the other groups in respect to color, flavor, taste, texture, and overall acceptance. Notably, as the Cirsium nipponicum powder content increased, there was an increase in the antioxidant activities; increased total pheonlic, flavonoid, DPPH radical scavenging activity and ABTS radical scavenging activity. Based on the present study results, adding 2% of Cirsium nipponicum powder into pork patties achieved the best functionality and sensory qualities.

본 연구는 햄버거 패티 제조시 우지를 대체한 canola oil, olive oil, corn oil 및 sunflower oil 등의 식물성 유지와 결착 보조제로 egg white powder와 wheat fiber 를 첨가하여 품질 특성을 조사하였다. 식물성유를 첨가한 햄버거 패티는 일반적인 우지를 첨가한 패티보다 낮은 칼로리와 가열감량 및 직경감소율을 나타내었고, 물리적 측면 및 관능적 특성에서는 우지를 사용한 패티와 큰 차이를 나타내지 않았다. 지방산 조성 분석 결과, 우지를 사용한 패티에 비해 낮은 트랜스 지방산 함량과 낮은 포화지방산 함량을 나타내었다. 따라서 식물성유를 대체할 때 대두단백, egg white powder 및 wheat fiber를 일정량 혼합하여 첨가한다면, 트랜스 지방산의 함량을 낮추고, 많은 불포화 지방산의 함량이 높은 웰빙형 햄버거 패티의 개발이 가능할 것으로 사료된다.

Brewer's spent grain (BSG) is a by-product of beer manufacturing. This study was conducted to evaluate the effect of dietary fiber extracts from brewer's spent grain on quality characteristics of chicken patties. The total fiber content of BSG dietary fiber extracts after extraction increased from 58.11% to 68.57%, and the extracted dietary fiber extracts were added to chicken patties at 0, 1, 2, 3, and 4%, respectively. The effects of the BSG dietary fiber extracts on pH, color, cooking loss, reduction in patty diameter, salt-soluble protein solubility, texture, and sensory characteristics of chicken patties were evaluated. The addition of BSG dietary fiber extracts decreased pH and lightness values, and increased redness and yellowness. Chicken patties formulated with 3-4% BSG dietary fiber extracts had the lowest cooking loss among all treatments (p<0.05). The diameter of chicken patties was not affected by the addition of BSG dietary fiber extracts. Additionally, no significant difference was observed in salt-soluble protein solubility after adding 3% BSG dietary fiber extracts compared to that in the control. Textural and sensory properties were different among the chicken patties, and the 3% BSG dietary fiber-added chicken patty had the highest acceptability. Our results indicate that 3% BSG dietary fiber extract can be used as a good source of dietary fiber for improving the quality characteristics of chicken patties.

Time-temperature integrators (TTIs) are simple and cost-efficient tools which may be used to predict food quality. Enzymatic TTIs are devised to indicate food quality in the form of color alterations from green to red, based on the cumulative impacts of temperature and time period on the enzymatic reactions. In this study, the quality of ground beef patties was investigated for the parameters of pH levels, color, VBN, water holding capacity, and total microbial counts, depending on various storage temperatures (5, 15, and $25^{\circ}C$). TTIs were attached to the surface of the ground beef patties in order to evaluate the degree of correlating colorimetric changes with the determined quality parameters. Through the Arrhenius equation, activation energy and constant reaction rates of TTI, VBN, and total microbial counts were calculated as to observe the relationship between enzymatic reactions of the TTI and food spoilage reactions of the ground beef patties. VBN and total microbial counts were already increased to reach decomposition index (VBN: 20, total microbial count: 7-8 Log CFU/g) of meat at middle stage of storage period for each storage temperature. Although activation energy of TTI enzymatic reactions and food spoilage reactions of the ground beef patties were similar, the change of TTI color was not a coincidence for food spoilage at $5^{\circ}C$ and $15^{\circ}C$ of storage temperature. It was suggested that TTI should be designed individually for storage temperature, time, type of meat, or decomposition index of meat.
