To prepare high-quality fast foods using salmon, this study developed a docosahexaenoic acid (DHA)-enriched salmon patty, and compared its quality with soybean oil-added patty and commercial patty. The moisture and lipid contents of the DHA-enriched patty were 61.9% and 7.7%, respectively. The moisture content was lower than in the commercial patty, while the lipid content was higher. The lipophilic and hydrophilic browning indices of the DHA-enriched patty were 0.10 and 0.05, respectively, which were lower than those of the commercial patty. The DHA-enriched patty had 5% less trichloroacetic acid (TCA)-soluble nitrogen than the commercial patty, and it was firmer. There were no differences in the proximate composition, browning indices, TCA-soluble nitrogen content, and hardness between the soybean-added and DHA-enriched patties prepared in this experiment. Examining the fatty acid compositions of the patties, the saturated acid and monoenoic acid compositions decreased in the following order: DHA-enriched patty > soybean oil-added patty > commercial patty, while the polyenoic acid composition increased in that order. The total amino acid content of the DHA-enriched patty was 19.13 g/100 g, which was 32% higher than that of the commercial patty (14.47 g/100 g). No enriching effect of minerals would be expected on eating a 100 g DHA-enriched patty, except for phosphorus. The sensory evaluation indicated that the DHA-enriched patty was superior in color and taste to the commercial patty, while there was no difference in flavor between the patties.

This study was carried out to investigate the effect of mugwort podwer and carcass grade on the shelf-life of pork patty. Pork patty was prepared by four types such as grade B pcrk patty without mugwort powder (A patty), grade B pork patty with mugwort podwer (B patty), grade I pork patty without mugwort powder (C patty) and grade E pork patty with mugwort powder (D patty) and the residual nitrite, surface color, pH, VBN (volatile basic nitrogen), TBARS (2-thiobarbituric acid reactive substances) and total bacterial counts of the sample were determined during storage at 4$^{\circ}C$. The residual nitrite of pork patties with mugwort powder was highly decreased until storage for 2 weeks, pork patties without mugwort powder highly decreased until storage for 4 weeks, therefore addition of mugwort powder reduced residual nitrite of pork patty. The L＊ value of pork patty was the highest at early stage of storage, pork patties with mugwort powder were lower than that of pork patties without mugwort powder, and grade B pork patties were higher than that of the grade I pork patties. The a value of grade I pork patties were higher than that of grade B pork patties, and changes during storage were no significant difference. The b value of grade B pork patties were higher than that of grade I pork patties. The pH of pork patties decreased during storage. The VBN, TBARS and total bacterial counts added significantly during storage, and the addition of mugwort powder were not affected during storage.

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.
