This study evaluated the antibacterial and antioxidant activities of ethanol extract of calamansi pulp (CPE) and its effect on quality and biogenic amine (BAs) formation in pork patties during storage. The CPE were prepared in various conditions (ethanol concentrations of 50%, 70%, and 90% with extraction periods of 3 and 6 days). The extract with potent antibacterial and antioxidant activities (90%, 6 days) was selected for addition to pork patties. Three groups were tested: Control (without extract addition), CPE addition at 0.2% w/w (0.2PCPE), and 0.4% w/w (0.4PCPE). The addition of CPE inhibited the formation of BAs, mainly cadaverine, histamine, and tyramine, in pork patties during storage. The pH and bacterial count of pork patties decreased significantly in a concentration-dependent manner following the addition of CPE. The instrumental color (CIE L^*, CIE a^*, and CIE b^*) tended to be higher in 0.4PCPE than in the control during storage. The thiobarbituric acid reactive substances and volatile basic nitrogen (VBN) values of pork patties were affected by CPE, showing a reduction toward lipid oxidation at any storage period, and maintaining the lowest VBN value in 0.4PCPE at the final storage day. Similarly, the reduction of total BAs in pork patties was observed ranged between 3.4%-38.1% under treatment with 0.2% CPE, whereas 18.4%-51.4% under 0.4% CPE addition, suggesting significant effect of CPE to improve meat quality. These novel findings demonstrate the efficacy of 0.4% CPE as a natural compound to preserve the quality and reduce BAs formation in pork patties during storage.

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.

본 연구는 감귤껍질 첨가가 돈육 patty의 냉장저장 중 이화학적 품질에 미치는 영향을 규명하고자 하였다. 돈육 patty는 돈육 68%, 돼지지방 20%, 소금 2%, 냉수 10%를 배합하여 제조한 대조군(T0), 여기에 감귤껍질 0.3% 첨가한 T1, 0.7% 첨가한 T2 그리고 1.0%를 첨가한 T3 등 네 종류의 돈육 patty를 제조하였다. pH는 저장 중 일률적인 변화를 보이지 않았으며, T2 및 T3가 T0 및 T1보다 낮았다. 명도는 저장 중 변화가 없었으며, 시료들 사이에도 차이가 없었다. 저장 중 적색도는 감소하였으며, 대조군이 가장 낮았다. 황색도는 저장중 유의한 변화가 없었으며, 감귤껍질을 첨가한 돈육 patty가 높았다. TBARS는 저장 중 유의하게 증가하여 저장 10일째 T0, T1, T2 및 T3가 각각 0.82, 0.32. 0.26 및 0.26 mg/kg을 나타내었다. DPPH 라디칼 소거활성은 저장 중 유의하게 감소하여 저장 10일째 각각 10.48, 23.76, 27.60 및 29.26%를 나타내었으며, T2 및 T3가 T0 및 T1보다 높았다. VBN 함량은 T0 및 T1는 저장 중 증가하여 저장 10일째 각각 11.66 및 10.40 mg%를 나타내었으며, 저장 10일째 대조군인 T0가 가장 높았다. 저장 중 보수력은 감소하여 저장 10일째 각각 75.58, 75.83, 75.71 및 75.16%를 나타내었으며, 감열감량은 저장 중 증가하여 저장 10일째 각각 23.69, 23.16, 22.98 및 23.92%를 나타내었다. 그러나 시료들 사이에는 보수력과 가열감량의 차이가 없었다. 경도는 저장 10일째 $3.20{\sim}3.34g/cm^2$로 증가하였으며, 씹힘성은 13.12~13.53 g으로 증가하였다. 탄성은 저장 10일째 49.34~50.12%로 감소하였으며, 응집성은 56.81~57.48%로 감소하였다. 그러나 시료들 사이에 경도, 씹힘성, 탄성 및 응집성은 차이가 없었다. 이상의 결과에서 감귤껍질은 항산화 작용이 있으면서 물리적 특성에 영향을 미치지 않았기 때문에 천연 항산화제로서 이용이 가능하며, 육 제품 고유의 색깔을 고려하면 0.7%의 첨가가 적당할 것으로 판단된다.

The aim of this study was to investigate the effects of the addition of red wine of pork patties during frozen storage on their water holding capacity, thawing loss, cooking loss, diameter change, thickness change, surface color, pH, VBN (volatile basic nitrogen) and TBARS (2-thiobarbituric acid reactive substances). Four types of pork patty were prepared; pork patty without red wine (control), and with the addition of 1%, 3% and 5% red wine (RWP-1, 3 -and t respectively). The pork patties were stored for 5 months at $-20^{\circ}C$. The water holding capacity was significantly decreased during frozen storage, which was not influenced by the addition of red wine (p<0.05). The thawing loss and cooking loss were significantly increased during frozen storage, which also was not influenced by the addition of red wine (p<0.05). There were no significant differences in the diameter and thickness changes during frozen storage, which was not influenced by the addition of red wine (p<0.05). There were no significant differences in the $L^*\;and\;b^*$ values, but the a value was significantly decreased during frozen storage. The $L^*,\;a^*\;and\;b^*$ values of the pork patties containing red wine were lower than those of the control patties (p<0.05). There were no significant differences in the pH and VBN content during the frozen storage period or on the addition of red wine to the patties. The TBARS value of the pork patties tended to increased with increasing in frozen storage period, but were decreased with increasing amount of red wine addition (p<0.05).

Marine fish skin peptides (FSP) have been widely studied due to their antioxidant and antimicrobial properties. We aimed to use a natural antioxidant, FSP, to replacing synthetic preservatives in a pork patty model, which is safer for human body. Moreover, nano-liposome technology can be applied for masking the fishy smell and improving the stability of this peptide. Therefore, in this study, the effects of FSP and FSP-loaded liposomes (FSPL) on pork patty were evaluated through the tests of thiobarbituric acid reactive substances (TBARS), color, cooking loss, texture, volatile basic nitrogen (VBN), and the pH value, during 14 d of refrigerated ($4^{\circ}C$) storage. The results showed that all FSP-treated patties had lower TBARS values than control patties, which indicated an inhibitory effect of FSP on lipid oxidation. This effect in the patties depended on the FSP concentration. However, FSPL-treated patties showed significantly higher and undesirable TBARS values compared to the control, and this effect depended on the FSPL concentration. None of the physicochemical results showed remarkable changes except the pH and VBN values. Therefore, this study provides evidence that FSP has great potential to inhibit the lipid oxidation of pork patties and is capable of maintaining the quality and extending the shelf life. However, it is necessary to study the application of FSP treatments greater than 3% to improve the antioxidant effect on pork patties and search for other coating materials and technology to reduce the drawbacks of FSP.

This study was carried out to evaluate the different physicochemical properties of various lipid sources in beef patties during storage for 6 months. Four groups of samples were made of beef meat patties with 22% of tallow, lard, chicken fat and 20% of palm oil. On the analysis result of physicochemical compositions, the patty has its own fatty acids composition and characteristic different from other lipids. Patty with chicken fat has the highest percentage of unsaturated fatty acid composition of 61.0% compared to the other groups of patties. Beef patty with chicken fat has 18.8% of poly unsaturated fatty acid(USFA) and beef patty with beef lipid has 1.5% of poly USFA which is the least percentage among the others. SFA/USFA ratio of beef patty with chicken lipid was 0.5 which was the least value. The composition of PUFA in beef patty with lard increased to 10.0% from 1.9% over initial value after storage for 6 months. On the contrary, the composition of PUFA in beef patty with chicken fat decreased to 9.2% from 18.8% over initial value after 6 months. Volatile free fatty acids of beef patties were evaluated with four kinds of lipid sources. Formic acid was the most as of 59$\mu\textrm{g}$/g in beef patty with tallow, acetic acid was 15$\mu\textrm{g}$/g, and heptanoic acid was 10$\mu\textrm{g}$/g at starting time of storage. However, propionic acid, butyric acid, valeric acid and caproic acid were not detected. After 6 months, formic acid decreased from 59$\mu\textrm{g}$/g to 7$\mu\textrm{g}$/g in the patty with tallow, from 12$\mu\textrm{g}$/g to non-detect level in the patty with palm oil, but two the others patties slightly increased. Volatile compounds in meat patties were reported nearly 1000 kinds of chemical compounds. Beef patty with tallow has aldehydes 5.3, alcohol 1.3, hydrocarbon 0.8, ketones 0.2, ester 0.1, furans 0.1, acid 0.04, sulfur 0.03 in peak area at starting and increased to aldehydes 8.5, alcohol 2.1, ketones 0.5, ester 1.0, furans 1.5 in peak area during the storage. But only furans was not detected after 6 months of storage. From starting to 6 months, aldehydes increased 2∼10 times, alcohol increased 2∼3 times, acids 4∼50 times and ester 9∼20 times in beef patties with pork lipid, chicken lipid and palm oil. Some volatile compounds such as alcohol, aldehydes and acids in all kinds of patties significantly increased after 6 months of storage. These increases cause oxidative rancidity taste in meat patties. These results showed that selt-life of meat patties with 4 different lipids were not over 6 months even though they were stored at -20$^{circ}C$. Therefore, they should be classified as off-grade because of oxidative rancidity. Although beef patties with tallow are currently common type, the possibility for new type of hamburg patty can be developed by applying different lipids. Finally, we found out new type of beef patty added with lard, which has the best taste and quality compared to the other common types.

This study explored the physicochemical, textural, and sensorial properties of a meat analog (MA) as compared to beef and pork meats. Results illustrate that MA patties had lower moisture, fat, and protein content, as well as higher ash and crude fiber than beef and pork. Likewise, MA patties had a higher pH, lightness (L^*), and redness (a^*) than either beef or pork. Pork meat exhibited the highest released water (RW) and cooking loss (CL) values, followed closely by MA with beef displaying the lowest values. Regardless of patty type, the post-cooking diameter patties were reduced significantly (p<0.05). However, the Warner-Bratzler shear force (WBSF), hardness, chewiness, and gumminess of beef were significantly higher than that of either pork or MA. The visible appearance of MA patties had more porous and loose structures before and after cooking. Consequently, based on sensory parameters, MA patties demonstrated the higher values for appearance and firmness, followed by beef and pork respectively, although the difference was not statistically significant. Therefore, the current study demonstrated that some physicochemical, textural, and sensory characteristics of beef and pork exhibited the most similarity to MA.

Korean traditional meat patties (Tteokgalbi) were prepared by replacing part of the lean meat content with either pork backfat or canola oil and the effect of substitution on sensory quality of the meat patties was investigated. Compared to the control patties, pork-loin Tteokgalbi with 10% pork backfat or 10% canola oil had significantly higher overall acceptability and higher perceived intensity of meat flavor, sweetness, umami, and oiliness. The pork-loin patties containing 10% fat also had lower perceived firmness, toughness, and chalkiness of than the control Tteokgalbi. The chicken breast Tteokgalbi with 10% canola oil had the lowest perceived firmness and chalkiness (control > pork backfat > canola oil). No significant difference was noted in the overall acceptability of chicken breast patties with 10% pork backfat and those with 10% canola oil. These results indicate that substituting 10% of lean meat of Tteokgalbi with fat improved the sensory acceptability of the product for Korean customers regardless of the lean meat and/or fat source used in the patties. Lean meat patties formulated with a limited amount of vegetable oil such as canola oil can be a healthy option for Korean consumers by providing desirable fatty acid profiles without sacrificing sensory quality of the product.

This study was carried out to investigate the cooking properties and lipid oxidation stability during storage at $4{\pm}1^{\circ}C$ when the various levels (5 to 20%) of doenjang (Korean fermented soybean paste) were added to pork patties cooked by pan frying (PF) and convection oven (CO). With increasing the addition of doenjang, cooking properties of pork patties revealed the improved cooking yield, less diameter reduction, and less thickness increase. Also, the shear force, hardness, and chewiness of pork patties were reduced. The PF cooking method showed better cooking properties than CO. Lipid oxidation expressed by the thiobarbituric acid reactive substances (TBARS) values was significantly reduced by the addition of more than 5% doenjang (p<0.05). The TBARS values of cooked pork patties by PF were significantly lower than CO during the 8 days of the storage (p<0.05). The development of warmed-over flavor (WOF) in cooked pork patties was delayed as the amount of the doenjang was increased. It was suggested that the addition of doenjang and PF favorably affected the cooking properties and stability of lipid oxidation in pork patties.
