  • Objective: The objective of this research was to evaluate the physico-chemical, microbiological and sensorial qualities of restructured steaks processed from beef trimmings (grade I and II) and frozen beef (fresh beef as control and frozen beef). Methods: Beef trimmings from commercial butcher were collected, designated into 4 treatments differing in beef trimmings grade and freezing, processed into restructured steaks with 1% microbial transglutaminase and then analyzed for product quality. Results: The results showed that all meat from different groups could be tightly bound together via cross-linking of myosin heavy chain and actin as observed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Microbial counts of psychrotrophic and mesophilic bacteria were not affected by treatments (p>0.05), and no detectable of thermophilic bacteria were found. Regarding effect of beef trimmings grade, steaks made from beef trimmings grade II (16.03% fat) showed some superior sensorial qualities including higher tenderness score (p<0.05) and tendency for higher scores of juiciness and overall acceptability (p<0.07) than those made from beef trimmings grade I (2.15% fat). Moreover, a hardness value from texture profile analysis was lower in steaks processed from beef trimmings grade II than those made from grade I (p<0.05). Although some inferior qualities in terms of cooking loss and discoloration after cooking were higher in steaks made from beef trimmings grade II than those made from beef trimmings grade I (p<0.05), these differences did not affect the sensory evaluation. Frozen beef improved the soft texture and resulted in effective meat binding as considered by higher cohesiveness and springiness of the raw restructured product as compared to fresh beef (p<0.05). Conclusion: The results indicated the most suitable raw beef for producing restructured steaks without detrimental effect on product quality was beef trimmings grade II containing up to 17% fat which positively affected the sensory quality and that frozen beef trimmings increased tenderness and meat binding of restructured beef steaks.

  • The effects of various dietary fats on plasma lipids. liver lipids, and Plasma Peroxide levels were studied in rats fed for 6 wk with diets containing 15 wt% fat, as sesame oil. raw perilla seed oil. roasted perilla seed oil, heated perilla seed oil. mackerel oil or beef tallow. TBA values of these lipids during 4 wk storage, and linolenic acid contents of three kinds of perilla seed oil were also measured. Linolenic acid contents of raw perilla seed oil. roasted perilla seed oil and heated perilla seed oil were 62.3%, 61.6% and 53.1% respectively. Raw perilla seed oil showed the lowest rate of lipid peroxidation after 4 wk storage at 4$^{\circ}C$, and mackerel oil showed the highest peroxidation rate. The plasma cholesterol levels of rats consuming diets in which the carbohydrate was rice were not affected by n-3 PUFA. Rather, the degree of peroxidation seems to have a direct effect on cholesterol levels as shown by the hypocholesterolemic effect of raw perilla seed oil and beer tallow. However. the HDL-cholesterol level was greater in rats fed either roasted perilla seed oil or mackerel oil. Rats fed roasted perilla seed oil and raw perilla seed oil had lower levels of plasma triglycerides than rats fed beef tallow. In rats fed roasted perilla seed oil, the total lipid and cholesterol contents of liver were significantly lower than in those fed the other kinds of perilla seed oil. The plasma lipid peroxide levels were lower in rats fed either roasted perilla seed oil or beef tallow.

  • In order to investigate the possibility of low fat meat products, beef patties were prepared with gumssuch as carrageenan, methyl cellulose, and xanthan gum. The quality characteristics of beef patties were examined. Moisture contents of raw and cooked patties of control were lower than those of patties containing gums. and fat content was higher than those of containing gums. There was no significant difference in the protein contents of patties. In case of L-value(lightness) of raw patty, the control was higher than those patties containing gums. a- ( redness) and b-value(yellowness) among patties were not significantly different. Cooking yield, fat retention, and water holding capacity of beef patties containing gums were higher than control beef patty, but salt soluble protein and gel strength were not significantly different. Significant difference did not exist among beef patties in hardness, but the chewiness and gumminess of patties containing gums were higher than control. In case of sensory evaluation, there was no significant difference among patties in aroma and palatability. Texture of control was higher than patties containing gums, and juiciness of control was higher than patties containing carrageenan.

  • Objective: This study was to determine the bacterial diversity and monitor the community dynamic changes during storage of vacuum-packaged sliced raw beef as affected by Lactobacillus sakei and Lactobacillus curvatus. Methods: L. sakei and L. curvatus were separately incubated in vacuumed-packaged raw beef as bio-protective cultures to inhibit the naturally contaminating microbial load. Dynamic changes of the microbial diversity of inoculated or non-inoculated (control) samples were monitored at $4^{\circ}C$ for 0 to 38 days, using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). Results: The DGGE profiles of DNA directly extracted from non-inoculated control samples highlighted the order of appearance of spoilage bacteria during storage, showing that Enterbacteriaceae and Pseudomonas fragi emerged early, then Brochothrix thermosphacta shared the dominant position, and finally, Pseudomonas putida showed up became predominant. Compared with control, the inoculation of either L. sakei or L. curvatus significantly lowered the complexity of microbial diversity and inhibited the growth of spoilage bacteria (p<0.05). Interestingly, we also found that the dominant position of L. curvatus was replaced by indigenous L. sakei after 13 d for L. curvatus-inoculated samples. Plate counts on selective agars further showed that inoculation with L. sakei or L. curvatus obviously reduced the viable counts of Enterbacteraceae, Pseudomonas spp. and B. thermosphacta during later storage (p<0.05), with L. sakei exerting greater inhibitory effect. Inoculation with both bio-protective cultures also significantly decreased the total volatile basic nitrogen values of stored samples (p<0.05). Conclusion: Taken together, the results proved the benefits of inoculation with lactic acid bacteria especially L. sakei as a potential way to inhibit growth of spoilage-related bacteria and improve the shelf life of vacuum-packaged raw beef.

  • Chopped garlic was added to beef to determine its effect on the protein digestion during storage and heat treatment. The digestibility of raw beef without garlic was not significantly changed during storage at $4^{\circ}C$, but increased as garlic added and aging time increased. The optimal aging time and amount of garlic added was varied with heating time. Trypsin inhibitor did not change the digestibility of beef due to its thermal inactivation. Gel chromatography revealed that the lower molecular weight peptides(2,200~6,150 dalton) were shown in beef-garlic mixture through aging and heating procedure. When aged beef with garlic was digested with four-enzyme system, the soluble portion was increased significantly in comparison with that from raw beef without garlic. Protein quality of beef, as measured by computed PER(C-PER), was improved from 2.14 of raw beef to 2.50 of aged beef with chopped garlic.

  • The purpose of this paper on Hoe (raw beef) is to investigate various kinds of its recipes, with equal focus on seasonings and sauces as well as its main and sub ingredients. The recipes of Hoe can be broadly classified into four large groups such as Salkogi Hoe(Red meat Hoe), Hankazi Naechang-yook Hoe(made from internal organs), Jap Hoe(1)(miscellaneous Meat Hoe) and Jap Hoe(II)(rolled with a whole pinenut) while the cook books written before 1945 indicate that the number of recipes reaches up to 21. The recipe of Salkogi Hoe comprises following three steps. Cut raw beef into thin strips and season them if necessary, then sprinkling sufficient pinenut powder on the strips. Its main sauce is hot pepper paste with vinegar. The recipe of Hankazi Naechang-yook Hoe uses kidney, manyplies, liver and tripes as main ingredients. Kidney should be thinly sliced with mixture of salt, seasame salt, seasame oil, and pepper as its seasonings. Regarding Manyplies, liver and tripes, there exists two possible ways to season them after cutting into strips. You can season with sesame oil and pepper or only with salt. Main ingredients of Jap Hoe(I) consist of beef, pork, kidney, manyplies, liver and tripes, among which minimum two ingredients are selected. Ingredients selected are sprinkled with pinenut powder after cutting into thin strips. And Hot pepper paste with vinegar is used as main sauce. The recipe of Jap Hoe(II) is to cut manyplies into pieces of 2Cm by 5 Cm without removing their black part and roll each piece with a whole peanut in such a manner that the peanut sticks from rolled piece.
