Improvements in retail shelf-life of exported beef will help with merchandising and increase competitiveness in the worldwide market for US beef products. The objective of this study was to determine the effect of topically applying acerola cherry powder or rosemary extract from various suppliers on beef bone-in short rib steak and chuck roll steak shelf-life. USDA Choice beef bone-in short ribs (IMPS 123A) and chuck rolls (IMPS 116A) were aged (0°C) for 28 d post-fabrication. Following aging, 1.02 cm-thick steaks were cut (N = 126) and systematically assigned to a treatment based on steak location within the subprimal. Treatments included: untreated control (C), topically sprayed (2ml) with an acerola cherry powder solution (0.05%) from one of three suppliers (C1, C2, C3), or topically sprayed (2ml) with a rosemary extract solution (0.10%) from one of three suppliers (R1, R2, R3). Half of the steaks were assigned to d 0 lipid oxidation, metmyoglobin reducing activity (MRA), and oxygen consumption; the remaining steaks were assigned to color evaluation over 4 days of retail display followed by d 4 lipid oxidation and MRA. Short rib steaks treated with antioxidants had a brighter oxygenated lean color than control steaks (P < 0.001). There was an interaction (P = 0.028) between time of retail display and MRA. Short rib steaks treated with C3 and R2 did not change in MRA between d 0 and 4 (P = 0.620, P = 0.428, respectively). Chuck roll steaks treated with C1, C2, C3, R2, and R3, all had a higher, or more desirable, MRA than the control steaks on d 0 (P < 0.001). Applying topical antioxidants improves the shelf-life stability of steaks from beef bone-in short ribs and chuck rolls aged for an extended period.

Abstract Improving the shelf-life of beef bone-in short rib steaks, which are commonly exported, will increase beef export demand and subsequently producer profits. The objective was to determine the effect of the topical application of acerola cherry powder and rosemary extract from various suppliers on beef bone-in short rib shelf-life. Beef bone-in short ribs (IMPS 123A) (n = 18) from USDA Choice carcasses were aged for 28 days post-fabrication at 0°C. Steaks 1.02 cm-thick were systematically assigned based on location to treatments including: untreated control (C), topically sprayed (~2ml) with an acerola cherry powder solution (0.05%) from one of three suppliers (C1, C2, C3), or topically sprayed (~2ml) with a rosemary extract solution (0.10%) from one of three suppliers (R1, R2, R3). Steaks were assigned to day 0 lipid oxidation or 4 days of retail display followed by day 4 lipid oxidation. Steaks were weighed on day 0 and 4 to determine fluid loss. Throughout retail display, objective and subjective color were measured twice daily on the lean and bone marrow portions of the steaks. Data were analyzed using the Mixed Model procedure of the Statistical Analysis System. Lipid oxidation (P = 0.323) did not differ between treatments. However, treatments differed in fluid loss (P = 0.024), where steaks treated with C1, C2, C3, R2, and R3 had less fluid lost than control steaks. Subjective color evaluation of lean color (P < 0.0001) and uniformity (P < 0.001) differed between treatments. Steaks treated with C1, C2, C3, and R3 were a brighter red than control steaks. Treatments differed when measuring bone marrow L* (P < 0.001), a* (P < 0.001), and b* (P = 0.004), where R3 treated marrow was the darkest, reddest, and yellowest. Natural antioxidants, specifically acerola cherry powder and rosemary extract, improved steak color and water holding capacity of beef bone-in short ribs aged for an extended period.

Abstract This research was conducted to evaluate the effects of feeding different types of processed corn, with or without distiller grains, on shelf life of beef steaks. Steers (n = 240) were finished on Dry Rolled Corn (DRC), DRC + 30% Dried Distillers Grains (DDGS), Steam Flaked Corn (SFC), or SFC + 30% DDGS. Cattle were fed 10 per pen. Only pens with upper 2/3 Choice and Select-grade carcasses were sampled, with a goal of two (and a minimum of one) of each grade per pen. Three pens per treatment met the selection criterion and 36 carcasses were chosen (21 upper 2/3 Choice and 15 Select). Pen was considered the experimental unit. Both strip loins were collected from each carcass, halved, and aged for 2, 9, 16, or 23 d. After aging, steaks were placed under retail display for 7 d. Discoloration and objective color (L*, a*, and b*) were determined daily and lipid oxidation (thiobarbituric acid reactive substances; TBARS) was measured after 0 and 7 d of retail display. Fatty acid profile of the lean was obtained. Minimal to no impacts of grade on color and lipid oxidation were found (P > 0.05). Steaks from cattle fed DRC were statistically or numerically lowest for discoloration and C18:2 (linoleic acid) and highest for redness compared to the other treatments (P < 0.05). Conversely, steaks from cattle fed SFC+DDGS had the most C18:2 and the worst (least desirable) values for discoloration and redness toward the end of retail display (P < 0.05). Steaks from cattle fed DRC had the lowest TBARS values, while steaks from cattle fed SFC+DDGS had the highest TBARS values (P < 0.05). These data suggest that steaks from cattle fed SFC+DDGS oxidize, discolor, and lose redness more quickly under retail display than steaks from cattle fed DRC, likely due to changes in fatty acid content.

Wet Distillers Grains

Feeding wet distillers grains plus solubles (WDGS) in beef feedlot diets increases beef polyunsaturated fatty acids (PUFA) concentration and decreases shelf-life; whereas feeding antioxidants like vitamin E and Agrado-Plus (AG; an ethoxyquin and tert-Butylhydroquinone mixture) mitigates such effects. The objective of this study was to evaluate shelf-life of beef from steers supplemented with WDGS and different antioxidants. One hundred and sixty steers were finished on a corn-based diet with 0% WDGS or 30% WDGS and four antioxidant treatments (no supplementation; vitamin E only; AG only; vitamin E + AG). Ten strip loins from each treatment were collected, aged, cut into steaks, and placed under retail display (2 ± 2°C). During retail display, steaks were evaluated daily for objective colour and subjective discolouration. After retail display, steaks were used to measure lipid oxidation, muscle fatty acids, and vitamin E and ethoxyquin concentrations. Feeding 30% WDGS increased total PUFA in beef when compared with beef from steers fed 0% WDGS (P < 0.05). Supplementing vitamin E or vitamin E + AG was effective in decreasing myoglobin and lipid oxidation in steaks from steers fed 0% or 30% WDGS after retail display (P < 0.01). Supplementation of vitamin E or AG also increased (P < 0.01) muscle tissue vitamin E or ethoxyquin levels, respectively, compared with the diets without vitamin E or AG supplementation. The inclusion of 30% WDGS altered beef fatty acid profiles, but did not promote lipid and myoglobin oxidation compared with the 0% WDGS diet. Feeding vitamin E was effective, whereas supplementing AG had minor effects in decreasing myoglobin and lipid oxidation in steaks from both diet.

Textured Vegetable Protein

Blended meat/plant products are capturing industry market space at the retail counter for value-added beef products. Plant protein ingredients can be added to meat formulations to create appealing and functional products. Ground beef was combined with one of three plant protein inclusion treatments: control, pea, oat, or rice, along with 5% textured vegetable protein (TVP) and 1.5% soy protein concentrate then formed into 226 g patties containing up to 10% plant-based proteins. Patties were analyzed for fresh and cooked characteristics throughout a 5- or 7-day retail display. The inclusion of plant-based proteins negatively affected the instrumental tenderness values which were greater (p < 0.01) in plant-inclusion patties compared to the control patties. The inclusion of plant proteins increased (p = 0.01) the cooking yield of patties compared to the control. Cooking time was longer (p = 0.04) for oat patties compared to the control patties. Cooked color values for vegetable inclusion patties did not affect (p = 0.12) lightness (CIE L*) values; however, redness (CIE a*) was greater (p < 0.01) for rice than all other treatments and yellowness (CIE b*) values were greater (p < 0.01) for all protein treatments compared to the control. Rice improved (p < 0.01) fresh a* values on day 5 of display compared to the control; whereas pea decreased (p = 0.04) values compared to the control. There was a treatment × day interaction (p < 0.01) on lipid oxidation values with a reduction in values on day 3 for all vegetable proteins compared to the control and on day 7 lipid oxidation was reduced (p ≤ 0.03) for oat patties.

Discolored fresh meat products in a retail setting are often perceived negatively by consumers when making purchasing decisions. Prolonging fresh meat color is critical for the retail industry in regard to sales and consumer perception. Variation in retail display settings can impact meat color shelf life from both a discoloration and oxidation standpoint. Lighting technologies are known to impact meat discoloration due to light intensities and temperature variations. A growing demand for the use of energy efficient lighting sources such as light emitting diode (LED) bulbs is being adopted in the United States. Therefore, it is imperative to know the impact these new lighting technologies have on fresh meat quality. Three trials were conducted to determine the impact of LED lighting technologies in comparison to commonly used fluorescent (both low [FLO] and high - UV [HFLO]) bulbs, and no light source (DRK). In a study conducted on ground beef from the Semimembranosus (SM) (n = 20) patties at two different fat levels (5 and 25 percent) had superior a* values, oxymyoglobin concentrations (MbO2), and lipid oxidation levels (TBARS) than those treated with LED or FLO light sources over 7 days of retail display. Patties displayed under LED bulbs had higher a* values and MbO2 concentrations than patties displayed under FLO light sources. Data indicated that the use of LED bulbs on ground beef promoted greater red color retention and less oxidation than FLO bulbs in a retail display setting. To evaluate retail display settings and fresh beef cuts further, two whole muscle cuts one color labile cut (Triceps brachii [TB]) (n = 20) and steaks from the SM (n = 20), known to be moderately color stable were evaluated under HFLO, FLO, and LED light sources over 7 days of retail display. For both whole muscle cuts, the use of HFLO light sources promoted greater redness retention as indicated by MbO2 and a* values, less lipid oxidation as indicated by TBARS values, and less undesirable metmyoglobin (MMb) formation in comparison to steaks displayed under FLO or LED light treatments. The use of LED bulbs for prolonged ground beef retail display was superior to other light sources. However, ground beef is rarely displayed in retail settings for an extended period of time. The use of LED bulbs showed no advantages when displaying whole muscle cuts. Therefore, data from this study suggests while from an energy efficiency standpoint LED bulbs can be beneficial to retail settings. However, from a fresh meat quality standpoint, there is no advantage from color or oxidative standpoint for using LED lights in a retail display setting for fresh beef products.

This work reports the use of two monomers with two tertiary amines and four methacrylic (TTME) or acrylic (TTAC) terminal groups as co-initiators in the formulation of experimental resin adhesive systems. Both monomers were characterized by FT-IR and 1H NMR spectroscopies. The control adhesive was formulated with BisGMA, TEGDMA, HEMA, and the binary system CQ-EDAB as a photo-initiator system. For the experimental adhesives, the EDAB was completely replaced for the TTME or the TTAC monomers. The adhesives formulated with TTME or TTAC monomers achieved double bond conversion values close to 75%. Regarding the polymerization rate, materials formulated with TTME or TTAC achieved lower values than the material formulated with EDAB, giving them high shelf-life stability. The degree of conversion after shelf simulation was only reduced for the EDAB material. Ultimate tensile strength, translucency parameter, and micro-tensile bond strength to dentin were similar for control and experimental adhesive resins. Due to their characteristics, TTME and TTAC monomers are potentially useful in the formulation of photopolymerizable resins for dental use with high shelf-life stability.

Food emulsions with high amounts of unsaturated fats, such as mayonnaise, are prone to lipid oxidation. In the food industry, typically accelerated shelf life tests are applied to assess the oxidative stability of different formulations. Here, the appearance of aldehydes at the so-called onset time, typically weeks, is considered a measure for oxidative stability of food emulsions, such as mayonnaise. To enable earlier assessment of compromised shelf-life, a predictive model for volatile off-flavor generation is developed. The model is based on the formation kinetics of hydroperoxides, which are early oxidation products and precursors of volatile aldehydes, responsible for off-flavor. Under accelerated shelf-life conditions (50 °C), hydroperoxide (LOOH) concentration over time shows a sigmoidal curvature followed by an acceleration phase that occurs at a LOOH-concentration between 38–50 mmol/kg, here interpreted as a critical LOOH concentration (CCLOOH). We hypothesize that the time at which CCLOOH was reached is related to the onset of aldehyde generation and that the characterization of the LOOH-generation curvature could be based on reaction kinetics in the first days. These hypotheses are tested using semi-empirical models to describe the autocatalytic character of hydroperoxide formation in combination with the CCLOOH. The Foubert function is selected as best describing the LOOH-curvature and is hence used to accurately predict onset of aldehyde generation, in most cases within several days of shelf-life. Furthermore, we find that the defining parameters of this model could be used to recognize antioxidant mechanisms at play.
