Abstract This study determined the influence of packaging and muscle on beef flavor and tenderness. Strip loins and top sirloin butts (n = 20/subprimal) from USDA Low Choice carcasses were fabricated into 2.54 cm steaks (Longissimus lumborum and Gluteus medius) at 7 d postmortem. Steaks were randomly assigned to packaging treatments: carbon monoxide motherbag (CO), high oxygen modified atmosphere packaging (HIOX), polyvinyl overwrap (OW) and rollstock (ROLL) and aged for 14 d in dark storage. Steaks in OW were vacuum packaged during aging, then overwrapped for display. Steaks were placed in coffin-style retail display for 48-h under fluorescent lighting. For trained panels and Warner-Bratzler shear force (WBSF), steaks were cooked to 71℃ using clamshell grills. Seven trained panelists rated steaks for beef flavor identity, brown/roasted, bloody/serumy, fat-like, liver-like, oxidized, fishy, buttery, umami, bitter, sour, overall juiciness, and overall tenderness. Data was analyzed as a 2 × 4 factorial design, with packaging, muscle, and their interaction as fixed effects, peak temperature as a covariate, and collection, round, and panel as random effects. No interactions (P ≥ 0.103) or muscle main effects (P ≥ 0.063) were observed. Packaging impacted all traits (P ≤ 0.048), except for fat-like (P = 0.387), liver-like (P = 0.950), and salty (P = 0.357). Steaks from HIOX packaging were rated the lowest for positive flavor attributes and rated highest for negative flavor attributes. Conversely, OW and ROLL steaks produced the greatest positive flavor attributes in comparison with HIOX. Overwrap and ROLL steaks were juicier and more tender than HIOX steaks (P < 0.05). High oxygen steaks exhibited the highest WBSF value compared to all other treatments (P < 0.05). These results indicate HIOX packaging has detrimental effects on flavor and tenderness. Steaks should be stored and aged in anerobic packaging to maintain optimum levels of tenderness and flavor.

ObjectivesThe objective of this study was to determine the influence of packaging type on production of beef flavor volatile compounds.Materials and MethodsBeef strip loins (IMPS #180) and top sirloin butts (IMPS #184) were selected from USDA Low Choice carcasses (n = 40, 20/subprimal). Seven d postmortem, subprimals were fabricated into 2.54 cm representative steaks of the Longissimus lumborum (LL) and Gluteus medius (GM). Steaks were then placed into one of four randomly assigned packaging treatments: carbon monoxide motherbag (0.4% CO/30% CO2/69.6% N2; CO), high oxygen modified atmosphere packaging (80% O2/20% CO2; HIOX), traditional polyvinyl chloride overwrap (OW), and rollstock (ROLL). Steaks designated for the OW treatment were placed in ROLL treatment until retail display. Steaks were aged in the absence of light for 14 d, then subjected to a 48-h retail display under fluorescent lighting in coffin cases. Following retail display, steaks were immediately vacuum packaged and frozen at –20°C until further analysis. Prior to volatile compound analysis, steaks were thawed at 2–4°C. Steaks were then cooked to 71°C using clamshell grills. Immediately after cooking, six 1.27 cm cores were removed, then minced using a coffee grinder. Five g of sample was weighed into a glass vial, sealed, then analyzed using gas chromatography-mass spectrometry. Compounds evaluated were chosen from major flavor pathways.ResultsThree compounds, carbon disulfide, 2-pentylfuran, and benzaldehyde elicited a packaging type × muscle interaction (P ≤ 0.048). Carbon disulfide was present in the highest concentration (P < 0.05) in CO GM and ROLL LL steaks, but was present in the lowest amount (P < 0.05) in OW GM and ROLL GM steaks. For benzaldehyde, HIOX GM steaks produced the greatest concentration (P < 0.05) compared to all other treatments, with the exception of ROLL LL, which was similar (P > 0.05). A similar trend existed for 2-pentylfuran, as high oxygen GM steaks produced over three times higher concentrations (P < 0.05) of 2-pentylfuran compared to all other treatments. Nine compounds, primarily lipid derived, were impacted by a packaging main effect (P < 0.043). For 2-propanone, pentane, and hexanoic acid, methyl ester, HIOX packaging produced the greatest concentration (P < 0.05) compared to all other treatments. Additionally, HIOX steaks produced a greater amount (P < 0.05) of methanethiol than OW or ROLL steaks. High oxygen steaks produced more (P < 0.05) 1-pentanol, 1-octen-3-ol, and nonanal than CO steaks, but were similar to ROLL and OW steaks. Carbon monoxide packaging produced the greatest amount (P < 0.05) of 2,3-butanediol compared to all other treatments. Five compounds were impacted by the muscle main effect (P ≤ 0.039). The GM steaks produced a greater concentration of 2,3-butanedione (P = 0.011), 3-hydroxy-2-butanone (P = 0.002), octanoic acid (P < 0.001), and dodecanal (P = 0.021) than the LL steaks. The LL produced a greater amount of decanal (P = 0.039) than the GM.ConclusionThese results indicate packaging and muscle each impact flavor, however, packaging effects are primarily lipid derived and muscle more readily impacts Maillard product production. Additionally, HIOX packaging produces a large amount of lipid derived compounds from degradation and oxidation, which may form the basis for its negative flavor profile. This indicates HIOX packaging should be avoided to produce more positive flavor notes in beef.

The Impact

ObjectivesThis study aimed to evaluate the impact of retail display lighting and packaging type on beef flavor and lipid oxidation in five muscles.Materials and MethodsSubprimals (n = 40 strip loins, 60 shoulder clods, 60 tenderloins, 24 inside rounds, 60 top butts) were randomly collected from separate carcasses. At 7d postmortem muscles (Longissimus lumborum, LL; Triceps brachii, TB; Psoas major, PM; Semimembranosus, SM; Gluteus medius, GM) were fabricated and sliced to 2.54cm steaks. Per muscle, 120 steaks were randomly assigned to packaging treatments: vacuum rollstock (ROLL); high-oxygen (80% O2/20% CO2; HIOX); overwrapped in a motherbag with carbon monoxide (0.4%CO/30%CO2/69.6%N2; CO); and traditional overwrap (OW), which was vacuum packaged until immediately prior to display. Packages were stored in the dark at 2°C an additional 13 d prior to retail display, then were displayed under fluorescent lights (FL) or light-emitting diodes (LED) with a third treatment in dark storage (DARK). All were held in their respective light treatments at 2°C for 72h, then assigned for trained panels or chemical analysis, vacuum packaged and frozen at –20°C. For sensory analysis steaks were thawed to 4°C and cooked to 71°C. Panelists (n = 8) were trained to evaluate twelve flavors, overall juiciness and tenderness, which were scored on a 100-point scale (0 = not present; 100 = extremely present). Lipid oxidation of raw steaks was quantified as 2-thiobarbituric acid reactive substances (TBARS; mg malondialdehyde (MDA)/kg beef).ResultsNo three-way interaction (P ≥ 0.10) or lighting effect (P ≥ 0.09) was observed for trained panels or TBARS. Cardboard flavor had a muscle×lighting interaction (P = 0.02). In GM, FL had greater (p < 0.05) cardboard than other lighting; in other muscle types lighting was similar. Muscle×packaging influenced three attributes (P ≤ 0.02). Steaks in ROLL were sweeter (p < 0.05) than other packaging in GM, PM and TB; ROLL was juicier (p < 0.05) than other packaging in GM, PM, and SM. Across all packaging types tenderness was greatest for PM, while SM was least tender (p < 0.05) in CO, HIOX and OW packaging. Packaging influenced nine flavors (P ≤ 0.01); ROLL was greatest in beef ID, bloody/serumy, fat-like, umami, and salty, while HIOX scored greatest for oxidized, bitter, and sour. Brown/roasted was greatest (p < 0.05) in HIOX and CO. Muscle impacted liver-like flavor (P = 0.01), which was lower (p < 0.05) in SM than all other muscle types; LL, TB, PM and GM were similar (p > 0.05) for liver-like. Packaging influenced TBARS (p < 0.01); HIOX had the greatest concentration of MDA, followed by CO, OW and ROLL with the lowest (p ≤ 0.05). Muscle influenced TBARS (P < 0.01), where TB was greatest (p < 0.05), followed by SM, PM, and GM, which were similar (p > 0.05); LL had the lowest MDA concentration. Oxidized (P < 0.01, r = 0.34), cardboard (P < 0.01, r = 0.30), bitterness (P < 0.01, r = 0.23), and sourness (P < 0.01; r = 0.22) were positively correlated with TBARS, while beef ID (P < 0.01, r = –0.23), umami (P < 0.01, r = –0.23), and tenderness (P < 0.01; r = –0.21) were negatively correlated.ConclusionRetail display lighting did not directly influence sensory characteristics or lipid oxidation; lighting only impacted cardboard flavor in an interaction with muscle type. These results suggest after 72h retail display, flavor differences between steaks of similar muscle and packaging displayed under LED or fluorescent lights may not be distinguishable.

This study was conducted to determine the effect of electrical stimulation [control or stimulated (applied for 20 s using a constant current of 600 mA peak and maximum voltage of 550 V with a frequency of either 14 Hz or 10 Hz], ageing period (7, 21 or 35 days) and packaging method [modified atmosphere packaging (MAP) or overwrapped] on the retail display life of lamb [bone-in loin (M. longissimus thoracis et lumborum) chops and boneless leg steaks from the knuckle (M. quadriceps femoris)]. The colour and retail acceptability of lamb cuts were assessed both subjectively and objectively, using a chromameter, after 3 (midpoint of commercial retail display life; midpoint) and 5 (endpoint of commercial retail display life; endpoint) days for overwrapped product and at 5 (midpoint) and 9 (endpoint) days for MAP product. Retail display life of lamb (assessed both objectively and subjectively) was improved (P<0.001) by packaging lamb cuts into modified atmosphere compared with overwrapped lamb cuts. Electrical stimulation and length of ageing period before preparation into retail cuts did not influence colour or retail display life of lamb loin chops or leg steaks. Although the interaction of ageing period and packaging method were significant (P<0.001) for subjective colour, acceptability and retail grade of lamb loin chops and leg steaks at the midpoint of display life, these effects were inconsistent. This study highlighted that further work is necessary to determine potential means of improving the colour stability of lamb to enhance its retail display life, particularly cuts of the M. quadriceps femoris.
