The use of natural ingredients in meat processing has recently gained considerable interest, as consumers are increasingly attracted to clean-label meat products. However, limited research has been conducted on the use of natural substitutes for synthetic phosphates in the production of clean-label meat products. Therefore, this study aimed to explore the potential of oyster shell powder as a substitute for synthetic phosphates in pork patties cured with Chinese cabbage or radish powders. Four different groups of patties were prepared using a combination of 0.3% or 0.6% oyster shell powder and 0.4% Chinese cabbage or radish powder, respectively. These were compared with a positive control group that contained added nitrite, phosphate, and ascorbate and a negative control group without these synthetic ingredients. The results showed that patties treated with oyster shell powder had lower (p<0.05) cooking loss, thickness and diameter shrinkage, and lipid oxidation than the negative control but had lower (p<0.05) residual nitrite content and curing efficiency than the positive control. However, the use of 0.6% oyster shell powder adversely affected the curing process, resulting in a decreased curing efficiency. The impact of the vegetable powder types tested in this study on the quality attributes of the cured pork patties was negligible. Consequently, this study suggests that 0.3% oyster shell powder could serve as a suitable replacement for synthetic phosphate in pork patties cured with Chinese cabbage or radish powders. Further research on the microbiological safety and sensory evaluation of clean-label patties during storage is required for practical applications.

This study aimed to investigate the effect of ethanolic extracts from perilla leaves (PLE) on the quality attributes and polycyclic aromatic hydrocarbons (PAHs) in charcoal-barbecued pork patties. The PLE addition and doneness had no significant effect on the pH of pork patties (p>0.05). Regardless of the concentration, the PLE significantly lower malondialdehyde concentrations and reduced the CIE L^*, CIE a^*, and CIE b^* b^* when compared to control. The addition of 0.2% of PLE did not adversely affect the organoleptic properties of doneness of medium and well-done pork patties. Addition of PLE at 0.4% to medium-cooked pork patties had stronger suppressing effect on the formation of light PAHs compare to control (p<0.05), also adding it to well-done pork patties had the lowest concentration of 4 PAHs and 8 PAHs, and a total of 16 PAHs (p<0.05). Therefore, PLE at 0.4% can be used for suppressing the formation of PAHs and lipid oxidation in well-cooked pork patty.

In order to develop functional hamburger steak patties, various concentrations of lotus root (Nelumbo nucifera) were incorporated into them. The quality characteristics of the hamburger patties prepared after the addition of 5, 10, 15, 20 or 25% (w/w) lotus root were investigated. The moisture contents of the groups with lotus root were significantly higher than that of the control group. The crude fat and crude protein contents of the control group were higher than those of the other groups. No significant difference in the crude ash content was observed among the groups. The cooking loss rate, rate of reduction in diameter, and reduction in thickness of the groups with lotus root were significantly lower than those of the control group. Accroding to the results, lotus root inhibit cooking loss and help to keep moisture after cooking process. No significant difference in the L value was observed among the groups. The a and b values of the groups with lotus root were significantly decreased compared to those of the control group. No significant difference in hardness was observed among the groups. it suggest lotus root didn't affect the texture of hamburger patties. In the quantitative descriptive analysis, no significant difference in the color and fresh odor was observed among the groups. The groups with lotus root were softer than the control group. The groups with 10 to 25 % of lotus root showed higher juiciness and a sweeter taste than the control group. The preference of appearance, texture, flavor and overall acceptability of the groups with 10 to 25% lotus root were higher than those of the other groups, including the control group. In conclusion, lotus root can increase the acceptability of hamburger patties and 10-25% would appear to be the proper amount of it to use.

This study was conducted to investigate the effects of glucomannan (GMN), carrageenan (CAR), carboxymethyl cellulose (CMC), and transglutaminase-B (TGB) on the quality and storage properties of pork patties manufactured with pork skin connective tissue during 21 d of storage at $4^{\circ}C$. Results showed that CIE color values like lightness, redness and yellowness did not differ significantly among the pork patties. Sensory attributes also did not differ between the treatments (P>0.05). However, cooking loss was significantly lower in the group with added GMN, CAR, CMC, and TGB compared to the control at 21 d of storage. The shear force value of GMN and TGB were lower than the control at 21 d of storage (P<0.05). The pork patties added with GMN and TGB had lower thiobarbituric acid reactive substances (TBARS) values than the control at 1 or 21 d of storage (P<0.05). Volatile basic nitrogen (VBN) values of all treatment samples was lower than the control at 21 d of storage (P<0.05). Therefore, result of cooking loss suggested that the decrease in shear force in GMN and TGB were due to higher moisture retention. Also, the pork skin connective tissue with added GMN and TGB decreased lipid oxidation of pork patties.

This study was conducted to investigate the effect of propolis extract on chicken patty. the meat quality characteristics and storage properties of chicken patties without propolis extract were compared to those with 0.1%, 0.2%, and 0.4% propolis ethanol extract. The addition of propolis extract resulted in increased fat and ash content in the chicken patties. There were no differences in pH, water holding capacity, cooking loss, and texture profile analysis, indicating that the propolis extract did not negatively affect emulsification stability. However, sensory evaluation showed that the higher the concentration of propolis extract added, the lower the total preference of the chicken patties. Over a storage period, patties treated with propolis extract exhibited a lower total microbial count, and volatile basic nitrogen (VBN) content compared to those without propolis extract. Therefore, the addition of propolis to chicken patties does not reduce emulsion stability but improves storage properties. However, the unique flavor of propolis decreases the preference for chicken patties, so the amount must be considered when using it.

This study was performed to evaluate the antioxidant activity of oven-dried tomato powder (OTP) as affected by drying temperature and the effect of OTP on the product quality of pork patties. Three OTP products were obtained by drying of fresh tomato at 60, 80 and 100℃ oven until constant weight was obtained. Total phenolic content of three kinds of OTPs ranged from 1.95 to 5.94 g/100 g. The highest amount of total phenolic compound was observed in OTP dried at 100℃. Antioxidant activity of three kinds of OTPs was measured by 1,1-diphenyl-2-pycrylhydrazyl (DPPH)-radical scavenging activity, iron chelating ability, reducing power and measurement of lipid peroxide in linoleic acid emulsion system. In all parameters, OTP at 100℃ showed the higher antioxidant activity than other temperatures (p<0.05). Based on the model study, the physicochemical properties, and antioxidant and antimicrobial activities of pork patties containing 1% OTP were measured. Redness of pork patties were increased with the addition of OTPs (p<0.05). Thiobarbituric acid reactive substances (TBARS) values of raw pork patties containing OTPs were lower than those of control (CTL) until 7 d of storage, regardless of drying temperatures (p<0.05). Peroxide values of pork patties made with OTP (1%) were lower than those of CTL until the end of storage time (p<0.05). However, no antimicrobial activities were observed among the treatments (p>0.05). Therefore, OTPs could be used as a natural antioxidant in meat products.

The effects of tomato on the phsycochemical and sensory properties of meat patties during frozen storage were studied. Meat patties were produced with four different formulation including 0, 0.5, 1.0 and 1.5% chopped raw tomato. Meat patties made with the addition of tomato had higher(p<0.05) pH, L* and a* value than those of control sample. TBARS of all treatments were lower(p<0.05) when compared with those for control. In sensory evaluation, treatment groups resulted in slightly higher(p>0.05) score in overall acceptability. In the manufacture of functional meat patties containing tomato, further studied are needs on addition type and ratio of tomato materials during frozen storage than those of products without tomato.

Grape seeds and pericarp are rich in procyanidins, a class of natural antioxidants and antimicrobials that can provide phytonutrients for healthy eating and extend food shelf life. The objective of this study was to assess the effect of procyanidins as preservatives in pork meat patties for 14 d. Pork patties were treated with 0, 0.1, or 0.3% procyanidin, and meat color, pH, volatile basic nitrogen (VBN), 2-thiobarbituric acid reactive substance (TBARS) values, and microbial populations were determined during storage at 4℃ for 14 d. The color of pork patties treated with procyanidin showed lower lightness and higher redness values than untreated controls, and procyanidin treatment reduced pH values significantly (p<0.05). VBN values decreased significantly (p<0.05) with the 0.3% procyanidin treatment and increased significantly (p<0.05) during storage. TBARS values were markedly lower in procyanidin-treated meat than in the untreated control. In addition, procyanidin suppressed total bacterial colony and Escherichia coli counts significantly (p<0.05) relative to the control samples. Our findings suggest that procyanidin could be used as a food preservative in pork patties due to its natural antioxidation and antimicrobial activities, and that it may contribute to an improved healthy diet.

This study used glucomannan as a fat substitute to produce low-fat patties with chicken meat, of which consumer consumption is increasing. In the case of a cooked meat patty, the crude fat content of the group treated with glucomannan was higher than that of a control when cooked. The cooking loss and reduction rate in the diameter of the control patties were higher than those of the group treated with glucomannan. Cohesiveness and chewiness of the group treated with glucomannan were higher than those of the control. As a result of sensory evaluation, there were no significant differences in the tenderness, color, odor and overall taste among the patties, but the juiciness of the group treated with glucomannan was lower than that of the control. There were no big differences in the pH of the patties during the frozen storage period. The volatile basic nitrogen (VBN) content of all of the types of patties gradually increased up to 7.97-8.56 mg% at the fourth week of storage, but these VBN values are hygienically safe. From these results, there was no large quality difference between a low-fat chicken patty to which glucomannan was added and a control. Therefore, it was confirmed that a good quality low-fat chicken patty can be made by controlling the fat and glucomannan content.
