    Notes: Beef patties were processed from high pH (〉6.0) beef to contain 5, 10, 15, 20 or 25% fat. Patties were cooked to 71°C from the frozen or thawed state before evaluating color. Neither fat content nor state of patties when cooked exerted any major influence on color, but linear effects (p〈0.01) in association with increased fat content included higher L* values and hue angles and lower a* values (15.2% reduction). Higher values for L*, b* (but not for 5% fat patties), and hue angles were observed for patties cooked thawed rather than frozen. The use of high pH beef lessened the effects of increased fat and cooking from the thawed state on increased brown color in cooked patties.

    Notes: Two experiments were conducted to determine the effects of targeted fat level (0, 4, 8, 12, 16, 20%) on sensory, shear, cooking and chemical properties of ground beef patties. Frozen patties from all fat levels were cooked to achieve similar cooking yields. As fat levels decreased, tenderness, juiciness and flavor ratings decreased and shear force increased, with more pronounced differences at lower fat levels. Patties processed with 0% fat were rated lower in juiciness and flavor compared to all other fat levels. These studies suggested that alterations in processing and cooking would probably be necessary to achieve acceptance of extremely low-fat beef patties.

    Notes: Effects of fat level (14, 19, 24%) and cooking method (electric broiling, charbroiling, conventional oven roasting, convection oven roasting, electric grill frying, microwave cooking) were evaluated with ground beef patties using descriptive attribute and texture profile panels. Higher tenderness and juiciness values were associated with higher fat levels in the patties. Texture profile evaluation indicated the higher tenderness associated with higher fat levels and conventional oven roasting to be due to less hardness, density and cohesiveness during initial biting of the sample. Microwave cooking produced low sensory panel ratings regardless of fat level, while patties cooked by frying had the highest ground beef flavor intensity scores. Major textural properties of cohesiveness, hardness and density were influenced by fat level in a similar manner for all cooking methods.

    Notes: Strip loins and eye of rounds from 16 beef carcasses were used to study the effects of electrical stimulation (ES), no stimulation (NS), hot-boning (HB), and cold-boning (CB) on bacteriological and shelf-life evaluations. Following 7 days of vacuum-packaged storage, coliform counts were higher in the drip fluid from strip loins and lean surfaces of eye of rounds from ES compared to NS carcasses. A major advantage for HB in this study was the additional time required in retail display before the occurrence of lean surface discoloration. A previously identified benefit of lighter lean color with ES beef in carcass and primal cut form was also found in this study during display of retail cuts.

    Notes: The longissimus (LD) and semimembranosus muscles (SM) were removed from one side of 24 mature, low quality cow carcasses within 3 hr of slaughter, while these muscles were removed from the opposite side 24 hr later following chilling at 3°C. Muscles from both sides were allocated to four processing systems, which included various combinations of immediate freezing, aging, blade tenderization, vacuum packaging, film wrapping and enzyme application. Hot boning resulted in decreased tenderness for the LD and the SM when braised. Aging of film-wrapped cuts for 7 days and vacuum-packaged cuts for 14 days prior to freezing produced the greatest improvements in tenderness. Strip loins from hot-boned, low quality mature cows can produce palatable steaks if aging, blade tenderization and enzymes are also used.

    Notes: Sixteen steer carcasses were selected to study effects of electrical stimulation, boning time and cooking methods on palatability traits, cooking loss and chemical composition of beef biceps femoris muscle. Eight carcasses were electrically stimulated and eight carcasses served as controls. The biceps femoris muscle was removed from one side of each carcass within 2 hr of exsanguination and from the remaining side following a 48-hr chill. Muscles were subdivided and cooked in either a convectional electric or a microwave oven. Electrical stimulation resulted in longer (P 〈 0.01) sarcomeres for cooked product but did not affect palatability traits, cooking loss or chemical content. Hot boning reduced (P 〈 0.01) cooking loss and tenderness, resulted in less (P 〈 0.05) total, soluble and insoluble collagen and increased the juiciness score and moisture percentage when compared with 48-hr boning. Microwave cooking produced a greater (P 〈 0.01) cooking loss and a higher shear force value than convectional electric cooking.

    Notes: The objective of the study was to evaluate the effects of frozen lean addition, patty size, and surface perforation on the palatability and cooking properties of ground beef patties. Eighteen ground beef formulations were prepared at a commercial plant from various raw material sources. Frozen lean from domestic, Mexican, and Australian sources were added at the 40% level. Control formulations were comprised of 40% unfrozen U.S. Cutter cow lean and 60% unfrozen U.S. Choice trimmings. Immediately after the patties were formed, the surface was treated in one of three ways: (1) “knife-like” perforations; (2) “waffle-like” perforations, and (3) no perforations. Patties were evaluated for differences in sensory, cooking, and physical properties. Use of frozen lean had no important effects on ground beef palatability or cooking properties. There was no advantage to subjecting the surface of the patty to a knife or waffle treatment.

    Notes: Hot processed ground beef was prepared by one of the following three grinding methods: (1) initial break with kidney plate followed by 0.3 cm final grind; (2) initial break with kidney plate, followed by 1.3 cm grind and 0.3 cm final; and (3) same as No. 2 except that the formulation contained no chilled U.S. Choice plates. Chilled beef (control) was ground through a 1.3 cm plate followed by a 0.3 cm final grind. At 3-hr postmortem, the semimembranosus and longissimus muscles were removed from one side of each hot carcass, while at 24-hr postmortem, the same muscles were removed from the opposite chilled sides. The remainder of the meat from the carcass was used for ground beef fabrication. U.S. Choice plates (conventionally chilled) were added (30% of the formulation) to the formulation in order to bring the final fat content to 21 × 2%. Total cooking loss was significantly less in the hot processed patties when compared to the chilled patties. Patties from hot-boned beef were more tender and juicy than patties from chilled beef. Method of grinding had no significant effect on any palatability trait except flavor intensity. Hot processed patties had significantly (P 〈 0.05) less configuration change during cooking than chilled patties. Percent diameter change was significantly less in hot processed patties as compared to chilled.

    Notes: Dry fermented salami was prepared from formulations in which 0, 15 and 30% levels of both mechanically processed beef product (MPBP) and structured soy protein fiber (SSPF) were incorporated. A 10-member trained sensory panel for flavor found that the frequency of undesirable flavors was highest for salami with 15% SSPF-pH 6.2-0% MPBP and lowest for 0% SSPF-15% MPBP and 0% SSPF-30% MPBP. A second l0-member trained panel found that the salami with 30% SSPF-0% MPBP was lightest in color, while a 116-member untrained panel found this formulation was undesirable in flavor, tenderness, and overall desirability. Instron and Hunter Color Difference measurements reflected a toughening and lightening of color, respectively, for the 30% SSPF-0% MPBP salami in contrast to those treatments made with MPBP. Data from objective measurements (Instron and Hunter Color Difference Meter) were combined for all treatments and showed that salami increased in firmness and darkened with drying time. Both the trained and untrained sensory panels rated salami manufactured with 15 or 30% MPBP as generally comparable to the control salami.
