The meats of tuna Thunnus albacares and swordfish Xiphias gladius are ideal for fish patty production, offering high nutrition and other health benefits. Although red fish meat, including tuna, is added for cost-effectiveness, swordfish white meat is also used, as its aroma resembles that of market-sold beef patties. Here, we assessed the different blending ratios of tuna red meat and swordfish white meat (60:40, 40:60, 20:80, and 0:100) to find the optimal combination for fish patty production. Regarding color, the heated fish patties exhibited increased redness (a*) and yellowness (b*) compared with those of non-heated ones, with similar brightness (L*). The heated patties also scored higher concerning hardness, springiness, gumminess, and chewiness. A higher proportion of swordfish white meat resulted in a softer texture, particularly in patties with a ratio of 40% red meat to 60% white meat. Considering the results of the texture comparison analysis, it is recommended that the texture be improved by increasing the physical property "softness." Sensory evaluations revealed that the addition of white meat led to increased scores in terms of smell, beef taste, texture, and elasticity. These results suggest that swordfish white meat, with improved overall quality, is a suitable raw material for fish patties. Accordingly, the recommended ratio of 20% tuna red meat to 80% swordfish white meat is optimal for fish patty production.

This study was conducted to investigate the effect of plant oils or egg white powder and wheat fiber on the quality properties of hamburger patties. Beef patties were manufactured from the control oil (tallow, 10%), CP (canola oil, 10%), OP (olive oil, 10%), COP (corn oil, 10%), and SP (sunflower oil, 10%). The patties that contained plant oils had lower cooking loss than the control patties. The CIE $L^{\ast}$-values before cooking were highest for the SP treatments and lowest for the control patties. In terms of the fatty acid composition, the plant oil treatments, regardless of cooking, had higher monounsaturated/saturated fatty acid (M/S) ratios than the control patties, but had lower trans fatty acid contents than the control samples. In the sensory evaluations, the color and overall acceptability were more highly evaluated in the control patties than in the patties that contained plant oils.

This study examined the effects of cooking temperature and onion (Allium cepa L.) tissue concentrate on heterocyclic amine (HCA) formation in fried ground beef patties. Various amounts of onion tissue (2.0, 5.0, and 10.0%, w/w) were added to the ground beef patties, which were then fried at two different temperatures (190 and $225^{\circ}C$) for 10 min/side. The ground beef patties fried at $190^{\circ}C$ and containing 10.0% (w/w) onion showed a 51% decrease in mutagenicity, and formation of 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) and 2-amino-1-methyl-6-phenylimidazo[4,5-b]-pyridine (PhIP) was reduced by 58% and 63%, respectively. For the patties fried at $225^{\circ}C$, total mutagenicity decreased by 35% and 48% with the additions of 5.0 and 10.0% (w/w) onion, respectively, and PhIP formation was reduced 50, 60, and 71% with the additions of 2.0, 5.0, and 10.0% (w/w) onion, respectively.

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.

Heterocyclic aromatic amines (HCAs) are potent mutagens and possible human carcinogens that are formed during the heating of protein-rich foods. The effects of preheating treatment of beef patties using a microwave prior to frying at $220^{\circ}C$ for 10 min on each side on the reduction of HCAs (amino-carbolines and amino-imidazo-azaarenes) were evaluated. The amount of HCAs was then evaluated by solid-phase extraction and high pressure liquid chromatography (HPLC) analysis. The beef patties were treated by microwaving for various times (0, 1, 1.5, 2, or 3 min) before pan-frying. The results revealed the presence of 3-amino-1-methyl-5H-pyrido[4,3-b]indole (Trp-P-2), 3-amino-1,4-dimethyl-5H-pyrido-[4,3-b] indole (Trp-P-1), 2-amino-6-methyldipyrido[1,2-a:3',2'-d]imidazole (Glu-P-1), 2-aminodipyrido[1,2-a:3',2'-d]imidazole (Glu-P-2), 9H-pyrido[3,4-b]indole (Norharman), 1-methyl-9H-pyrido[3,4-b]indole (Harman), 2-amino-9H-pyrido[2,3-b] indole ($A{\alpha}C$), 2-amino-3,8 dimethylimidazo[4,5-f]-quinoxaline (MeIQx) and 2-amino-1-methyl-6-phenylimidazo[4,5-b]-pyridine (PhIP) in all samples. However, microwave pretreatment for 1 min inhibited the formation of these HCAs by up to 90% when compared to the control.

This study was conducted to investigate effects of cooking method on physicochemical characteristics and qualities of hamburger patties processed with ground pork/beef meat $(20\%\;fat)$. Hamburger patties were cooked by electric griddling, fan frying, microwave, conventional cooking, and charbroiling. Cooking rates were affected by cooking methods, had the highest in patties cooked in microwave oven. Hamburger patties by microwaving were also higher moisture content, but were lower protein and fat content compared to other methods. Electric griddling and microwaving were higher cooking yield, lower diameter changes in patties than other methods, but pan frying showed the opposite effects. Higher values of hardness and brittleness in pan frying than those of other methods were showed, but pan frying had the highest overall acceptability in sensory evaluations.

This study was performed to investigate the quality characteristics, including sensory and physical properties, of hamburger patties added with spinach as a source of fiber. Hamburger patties were prepared with spinach at five different levels (5, 10, 15, 20, and 25%. Moisture contents of the groups with spinach were significantly higher than that of the control group. Crude fat and crude protein contents of the control group were higher than those of the group with spinach. Crude ash content of the control group was the lowest among the groups. No significant difference in pH was observed among the groups. The cooking loss rates of groups with spinach were significantly reduced compared to that of the control group. No significant difference in L value was observed among the groups. However, a value of the control group was higher than those of the groups with spinach. Otherwise, b value of the control group was lower than those of the groups with spinach. The hardness levels of the control groups were significantly higher than those of groups with spinach. In the quantitative descriptive analysis, green color and bitter taste of the groups with spinach were stronger than that of the control group. The preference levels for appearance of the groups with 10 to 15% spinach were higher than those of the other groups, including the control groups. Overall acceptabilities of the groups with 5 to 15% spinach were significantly higher than those of the other groups. In conclusion, spinach can increase the acceptability of hamburger patties, and 10 to 15% would appear to be the proper added amount.

The identification of pork in commercially processed meats is one of the most crucial issues in the food industry because of religious food ethics, medical purposes, and intentional adulteration to decrease production cost. This study therefore aimed to develop a method for the detection of pork adulteration in meat products using primers specific for pig mitochondrial DNA. Mitochondrial DNA sequences for pig, cattle, chicken, and sheep were obtained from GenBank and aligned. The 294-bp mitochondrial DNA D-loop region was selected as the pig target DNA sequence and appropriate primers were designed using the MUSCLE program. To evaluate primer sensitivity, pork-beef-chicken mixtures were prepared as follows: i) 0% pork-50% beef-50% chicken, ii) 1% pork-49.5% beef-49.5% chicken, iii) 2% pork-49% beef-49% chicken, iv) 5% pork-47.5% beef-47.5% chicken, v) 10% pork-45% beef-45% chicken, and vi) 100% pork-0% beef-0% chicken. In addition, a total of 35 commercially packaged products, including patties, nuggets, meatballs, and sausages containing processed chicken, beef, or a mixture of various meats, were purchased from commercial markets. The primers developed in our study were able to detect as little as 1% pork in the heat treated pork-beef-chicken mixtures. Of the 35 processed products, three samples were pork positive despite being labeled as beef or chicken only or as a beef-chicken mix. These results indicate that the developed primers could be used to detect pork adulteration in various processed meat products for application in safeguarding religious food ethics, detecting allergens, and preventing food adulteration.
