Effects of in ovo injection of L-ascorbic acid on growth performance, carcass composition, plasma antioxidant capacity, and meat quality in broiler chickens1,2,3.

The current study was designed to investigate the effects of the in ovo injection of different dosages of L-ascorbic acid (AA) on posthatch growth performance, carcass characteristics, plasma antioxidant capacity, and meat quality in broiler chickens. A total of 2,220 Ross 708 broiler hatching eggs containing live embryos at 17 D of incubation were subjected to 1 of 6 treatments (trt): non-injected control, saline-injected control, or saline containing 3, 6, 12 or 36 mg of AA. An Inovoject m semi-automatic multi-egg injector was used to inject a 100 µL volume of sterile saline (0.85%) alone or containing the different AA dosage into each egg. After hatch, 14 male hatchlings from each trt group were randomly selected and placed in each of 10 replicate floor pens for growth performance evaluation through 45 D posthatch. Chicks from the 3 and 6 mg AA trt groups had a higher average daily BW gain and a higher feed intake compared to the saline-injected control group during the grower phase. Chicks in the 12 mg AA trt group exhibited a better feed efficiency in the late finisher phase and the entire growing phase than those in the saline-injected control group. Higher thigh and leg percentages were observed in chicks from the 3 and 6 mg AA trt groups than in the non-injected control group. Compared to the non-injected or saline-injected control groups, birds in the 12 mg AA trt group were observed to have a lower plasma malondialdehyde content during the grower and finisher phases, and breast muscle tenderness was elevated in chicks from the 36 mg AA trt group. Taken together, these results suggest that the in ovo injection of AA (3 to 12 mg per egg) have lasting positive effects on the posthatch growth, leg muscle development, and systemic antioxidant capacity of broilers. Higher injected dosages of AA (36 mg per egg) may also have the potential to improve broiler meat quality.

Changes in the physiochemical, microbial, and sensory characteristics of fresh pork sausage containing rosemary and green tea extracts during retail display.

The effects of adding combinations of rosemary (R: 1500, 2000, 2500 ppm) and green tea (G: 100, 200, 300 ppm) extracts in combination with synthetic antioxidants on the physiochemical, microbial, and sensory characteristics of fresh pork sausage were evaluated. R and G improved (P < .05) oxidative stability as evidenced by lower TBARS. R2500 and G300 had fewer PPC than the control at d 7, 14, and 21 of storage. Consumer acceptability scores were greater (P < .05) in sausages with R and G when compared to the control, and the majority of the R and G treatments were liked by 98% of the respondents. Treatment combinations of at least R2000 and G200 were described by positive drivers of liking such as spice-complex, ginger, nutmeg, rosemary flavors and aromas and lower scores for descriptors such as rancid, fruity, and off-flavor/odor. This research demonstrates that rosemary and green tea extracts improved the keeping quality of fresh pork sausage under simulated retail display.

Meat quality traits and proteome profile of woody broiler breast (pectoralis major) meat.

Woody breast meat has recently become prevalent in the broiler industry in both the United States and European Union. Recent publications have described the meat quality characteristics of woody breast meat as having hardened areas and pale ridge-like bulges at both the caudal and cranial regions of the breast. The present study investigated the meat quality (pH, color, cooking loss, and shear force) and protein quality characteristics (protein and salt-soluble protein content) in woody breast meat as compared to normal breast meat. In addition, the differences in the muscle proteome profiles of woody and normal breast meat were characterized. Results indicated that woody breast meat had a greater average pH (P < 0.0001) and cooking loss (P = 0.001) than normal breast meat, but woody breast meat did not differ in shear force (P > 0.05) in comparison to normal breast meat samples. The L*, a*, and b* values of woody breast fillets were greater than normal breast fillets (P < 0.0001 to L*; P = 0.002 to a*; P = 0.016 to b*). The woody breast meat had more fat (P < 0.0001) and moisture (P < 0.021) and less protein (P < 0.0001) and salt-soluble protein (P < 0.0001) when compared with normal breast fillets. Whole muscle proteome analysis indicated 8 proteins that were differentially expressed (P < 0.05) between normal and woody breast meat samples. The differences in muscle proteome between normal and woody breast meat indicated an increased oxidative stress in woody breast meat when compared to normal meat. In addition, the abundance of some glycolytic enzymes, which are critical to the regeneration of adenosine triphosphate (ATP) in postmortem muscles, was lower in woody breast meat than in normal breast meat. Proteomic differences provide additional information on the biochemical pathways and genetic variations that lead to woody breast meat. Further research should be conducted to elucidate the genetic and nutritional contributions to the proliferation of woody breast meat in the United States.

Proteomic approach to characterize biochemistry of meat quality defects.

Proteomics can be used to characterize quality defects including pale, soft, and exudative (PSE) meat (pork and poultry), woody broiler breast meat, reddish catfish fillets, meat toughness, and beef myoglobin oxidation. PSE broiler meat was characterized by 15 proteins that differed in abundance in comparison to normal broiler breast meat, and eight proteins were differentially expressed in woody breast meat in comparison to normal breast meat. Hemoglobin was the only protein that was differentially expressed between red and normal catfish fillets. However, inducing low oxygen and/or heat stress conditions to catfish fillets did not lead to the production of red fillets. Proteomic data provided information pertaining to the protein differences that exist in meat quality defects. However, these data need to be evaluated in conjunction with information pertaining to genetics, nutrition, environment of the live animal, muscle to meat conversion, meat quality analyses and sensory attributes to understand causality, protein biomarkers, and ultimately how to prevent quality defects.

Exogenous Carbohydrate Reduces Cortisol Response from Combined Mental and Physical Stress.

Combined mental and physical stress is associated with exacerbated cortisol production which may increase risk for the progression of cardiovascular disease in individuals working in high-stress occupations (e.g., firefighters, military personnel, etc.). Carbohydrate (CHO) ingestion prior to physical stress may attenuate cortisol concentrations. This project was the first to investigate the effect of CHO ingestion on cortisol response from combined mental and physical stress. 16 men 21-30 years old were randomly assigned a 6.6% CHO beverage or non-CHO control 15 min prior to performing a dual-concurrent-stress challenge. This consisted of physical stress (i.e., steady state exercise) combined with computerized mental challenges. Blood was sampled 70, 40, and 15 min before exercise, immediately at onset of exercise, 10, 20, 30, 35 min during exercise, and 15, 30, 45, and 60 min after exercise. There was a significant main effect for treatment regarding mean cortisol concentrations (F=5.30, P=0.0219). The total area under curve for cortisol was less when CHO was ingested (T7=4.07, P=0.0048). These findings suggest that CHO ingestion immediately prior to combined mental and physical stress may attenuate cortisol responses.

Time-Mortality Relationships to Control Tyrophagus putrescentiae (Sarcoptiformes: Acaridae) Exposed to High and Low Temperatures.

Tyrophagus putrescentiae (Schrank) (Sarcoptiformes: Acaridae) is a widely distributed pest species that is of significant economic importance for dry-cured country hams. Methyl bromide was used for decades in country ham plants to control this pest, but now this fumigant is recognized as an atmospheric ozone-depleting compound and will be phased out for all uses in the near future. Of various chemical and nonchemical alternatives to methyl bromide, extreme temperatures are viable and straightforward nonchemical methods to control pests. This study evaluated the efficacy of high and low temperatures on mortality of mold mite in the laboratory. Ten eggs and a mixture of 40 adults and nymphs were separately exposed to different high and low temperatures, ranging from +35 to 45 °C and from -20 to +5 °C, for several periods of time. Mortality was assessed after a recovery period for each life stage. Tyrophagus putrescentiae eggs were found to be more tolerant to both high and low temperatures than were the mobile stages. Results showed that high temperatures from 40-45 °C killed all mites within 4 to 1 d, respectively, while -10 °C or lower killed all mites in less than 1 d. Regression analyses of mortality data as a function of exposure predicted times for achieving desired levels of mite mortality. This study suggests that extreme temperature treatment can play an important role in integrated pest management programs for dry-cured ham as an alternative to methyl bromide or other chemical treatments.

Monitoring Tyrophagus putrescentiae (Acari: Acaridae) With Traps in Dry-Cured Ham Aging Rooms.

Methyl bromide is the most effective fumigant for controlling the mold (or ham) mite, Tyrophagus putrescentiae (Schrank) (Acari: Acaridae), the most significant pest of dry-cured ham. However, methyl bromide is being phased out of use. Therefore, integrated pest management (IPM) methods should be developed to help control mites in dry-cured ham plants. The foundation of a successful IPM program is an effective monitoring program that provides information on pest presence and abundance over time. By using food-baited traps fabricated from disposable petri dishes and a dog food-based bait, mite activity over time and space was monitored in five dry-cured ham aging rooms from three commercial processing facilities that differed in their fumigation frequencies. Weekly sampling of the mite was conducted from June 2012 to September 2013. There were significant differences in the average weekly trap captures in all facilities, especially before and after fumigation, with the majority of mites in traps prior to fumigation. Mite numbers had a pattern of sharp decline after fumigation, followed by a steady increase until the next fumigation. Average trap captures varied due to trap location over the study period at all study sites, indicating that traps could be used to identify specific locations within an aging room where mite infestation of hams was more likely to occur. These findings can inform facility managers of mite population changes that can be used as one factor toward making pest management decisions and assessing the impact of fumigation or other pest mitigation actions.

The effect of feeding native warm season grasses in the stocker phase on the carcass quality, meat quality, and sensory attributes of beef loin steaks from grain-finished steers.

The objective of this study was to evaluate the effect of feeding native warm season grass (NWSG) to beef cattle during the stocker phase (110days) on carcass and meat quality. Treatments included Bermudagrass (BER), Indiangrass monoculture (IND), and a mixture of NWSG including Big Bluestem, Little Bluestem, and Indiangrass (MIX). Cattle were finished on grain (180days) in a commercial feedlot and carcass data were collected after harvest. The percentages of 'choice' carcasses were 100, 95.8, and 87 within MIX, BER, and IND treatments, respectively. Steaks from BER had greater (P<0.05) fat content, and lower (P<0.05) protein and moisture percentages when compared to steaks from IND and MIX treatments. However, steaks from the MIX and IND treatments had less (P<0.05) lipid oxidation than steaks from BER after 6days of refrigerated storage. Results indicate that NWSG could be effectively incorporated into forage systems for stocker cattle without compromising carcass and meat quality.

Developing food-grade coatings for dry-cured hams to protect against ham mite infestation.

Dry-cured hams may become infested with ham mites, Tyrophagus putrescentiae, during the aging process. Methyl bromide is the only known available fumigant pesticide that is effective at controlling ham mite infestations in dry cured ham plants. However, methyl bromide will be phased out of all industries as early as 2015 due to its status as an ozone-depleting substance. Research was conducted to develop and evaluate the potential of using food-grade film coatings to control mite infestations, without affecting the aging process and sensory properties of the dry-cured hams. Cubes coated with xanthan gum+20% propylene glycol and carrageenan/propylene glycol alginate+10% propylene glycol were effective at controlling mite infestations under laboratory conditions. Water vapor permeability was measured to estimate the impact of coatings during the aging process. It was evident that carrageenan/propylene glycol alginate coatings were permeable to moisture, which potentially makes them usable during aging.

Controlling pests in dry-cured ham: A review.

Dry-cured hams can become infested with ham mites, red-legged beetles, cheese skippers, and larder beetles during the aging process. Though other methods may be used for beetles and cheese skippers, methyl bromide is the only available fumigant that is effective at controlling ham mites in dry-cured ham plants in the United States. However, methyl bromide will be phased out of all industries by approximately 2015. This paper will review and explore potential alternatives that have been investigated to determine their feasibility for replacing methyl bromide to control pest infestations in dry-cured ham plants in the United States. Potential alternatives include: 1) fumigants such as phosphine and sulfuryl fluoride; 2) physical control approaches through cold treatment, modified atmosphere, inert dusts, etc.; 3) pesticides and bioactive compounds; 4) food-grade processing aids. The most promising potential alternatives to date include the use of propylene glycol on the ham surface, the exploration of alternative fumigants, and implementation of an integrated pest management plan.

Phosphine fumigation and residues in dry-cured ham in commercial applications.

Dry-cured hams often become infested with ham mites (Tyrophagus putrescentiae) during the aging process. Methyl bromide has been used to fumigate dry cured ham plants and is the only available fumigant that is effective at controlling ham mite infestations. However, methyl bromide will eventually be phased out of all industries. This research was designed to determine the efficacy of phosphine fumigation at controlling ham mites and red-legged beetles and any impact of phosphine fumigation on the sensory quality and safety of dry cured hams. Fumigation trials were conducted in simulated ham aging houses and commercial ham aging houses. Mite postembryonic mortality was 99.8% in the simulated aging houses and >99.9% in commercial aging houses three weeks post fumigation. Sensory tests with trained panelists indicated that there were no detectable differences (P > 0.05) between phosphine fumigated and control hams. In addition, residual phosphine concentration was below the legal limit of 0.01 ppm in ham slices that were taken from phosphine fumigated hams.

The effect of feeding native warm-season grasses during the stocker phase on meat composition, quality characteristics, and sensory properties of loin steaks from forage-finished cattle.

The objective of this research was to determine the quality of beef from cattle that were fed native warm-season grass (NWSG) in the stocker phase and forage finished on tall fescue. Seventy-two British crossbred steers were randomly allotted to 9 pasture plots with 3 different forage treatments that included Bermuda grass (BER), Indian grass monoculture (IND), and big bluestem, little bluestem, and Indian grass (MIX) and forage finished on tall fescue. Two steers were randomly selected from each pasture plot for meat quality analyses (n = 18). Carcasses graded 67% Select for IND and 17% for both BER and MIX treatments, respectively. All other carcasses received quality grades of Standard. Steaks from treatments did not differ (P > 0.05) in sensory attributes, average sensory acceptability, color, tenderness, pH, or bacterial counts at each storage time, with limited differences in aroma, flavor, and texture. The IND steaks had lower cooking loss (P < 0.05) than steaks from the MIX and BER treatments. Steaks from the BER treatment had higher thiobarbituric acid reactive substances values (P < 0.05) after 6 d of storage when compared with steaks from the MIX and IND treatments, which indicated a higher susceptibility to lipid oxidation. Cluster analysis was conducted to group consumers on the basis of their preference and liking of steak from the different forage treatments. On the basis of panelists' acceptability scores, consumers were grouped into 4 clusters. The largest group (60% of consumers) liked all treatments between moderately and very much. In addition, 17% of consumers preferred steaks from the IND treatment over the BER treatment, and 11% of consumers preferred steaks from the BER and IND treatments over steaks from the MIX treatment. Overall, results indicate that high-quality forage-fed beef can be produced when cattle are fed mixed NWSG, Indian grass, or Bermuda grass during the stocker phase and then finished on tall fescue.

Increased physical activity may be more protective for metabolic syndrome than reduced caloric intake. An analysis of estimated energy balance in U.S. adults: 2007-2010 NHANES.

BACKGROUND AND AIM: The purpose of this study was to examine the association between physical activity (PA), caloric intake, and Metabolic Syndrome (MetS) in a representative sample of the United States population. METHODS AND RESULTS: Data for 4327 adults from 2007 to 2010 NHANES were analyzed. MetS was defined using both ATPIII and AHA/NHLBI criteria. Weekly moderate and vigorous physical activity (PA) minutes from work, leisure-time, and transportation PA were used to estimate Total Energy Expenditure (TEE) from Basal Metabolic Rate (BMR) using the Harris-Benedict equation. Average total calories (KCAL) from two 24-h dietary recalls were used to compare energy intake and expenditure between subjects with and without MetS. An alpha of 0.05 was used to determine statistical differences. The age adjusted prevalence of MetS was 21.9% (95% CI 20.1-23.6) and 36.8% (34.7-39.0) using ATPIII and AHA/NHLBI criteria, respectively. The estimated population mean for KCAL/TEE was 0.83 (95% CI 0.82-0.84), and the mean for KCAL/BMR was 1.25 (95% CI 1.23-1.27). Subjects without MetS (MetS-) reported 36 ± 13 (ATPIII) and 45 ± 18 (AHA/NHLBI) more daily moderate PA minutes than subjects with MetS (MetS+). At each level of PA, MetS- consumed more calories relative to BMR and TEE than MetS+. For both normal and overweight adults, KCAL/BMR was higher for MetS- than MetS+. For all BMI groups, there were no differences between MetS- and MetS+ with respect to KCAL/TEE. Though MetS+ adults in either MetS criteria were generally less physically active, MetS- adults maintained a higher caloric intake relative to estimated energy needs. CONCLUSIONS: These results suggest energy needs may be distorted in Metabolic Syndrome and increased physical activity may be more protective than reduced caloric intake.

Sensory quality of broiler breast meat influenced by low atmospheric pressure stunning, deboning time and cooking methods.

Stunning method (low atmospheric pressure stunning, LAPS and electrical stunning, ES), deboning time (0.75 h and 4 h), and cooking method (baking, frying, and sous vide) were evaluated for their impact on the descriptive sensory characteristics and consumer acceptability of breast meat (n=576, 144 birds per stunning × deboning time combination). Sensory evaluation was conducted by trained descriptive (n=8) and consumer (n=185) panels. On average, no differences (P>0.05) existed in the sensory acceptability of fried and sous vide cooked broiler breast treatment combinations. However, for oven-baking, the LAPS treatment that was deboned at 4 h was more acceptable (P<0.05) than other treatments and the ES and LAPS 4 h samples had greater (P<0.05) acceptability for texture than their ES and LAPS 0.75 h counterparts. Since consumers were highly variable in their liking of chicken breast treatments, consumers were grouped into clusters for each cooking method based on liking and preference. Cluster analysis data revealed that the largest groups of consumers liked (score≥6.0) all chicken breast treatments, but a larger proportion of consumers liked the 4 h LAPS and ES treatments when compared to the 0.75 h LAPS and ES treatments for all cooking methods. In addition, the consumers who indicated that baked chicken breast was highly acceptable preferred (P<0.05) 4 h LAPS over the 4 h ES samples. Based on sensory results, chicken breast meat from all stunning and deboning method combinations was highly acceptable to the majority of consumers, but the LAPS 4 h treatment had enhanced sensory characteristics when baked.

Impact of sodium lactate and vinegar derivatives on the quality of fresh Italian pork sausage links.

Sodium lactate and acetic acid derivatives were evaluated for their impact on fresh Italian pork sausage using commercial trimmings. Analysis over storage included total plate count (TPC), TBARS, sensory analysis, cooking loss, pH, and color. Treatments included: (a) vinegar and sodium lactate mixture (V), (b) sodium lactate (S), (c) positive control with BHA/BHT (B) and (d) negative control, seasoning only (C). Treatments S and V had lower TPC (P<0.05) from days 5 to 14 when compared to B and C. TBARS values increased (P<0.05) for C, S, and V while B did not change (P>0.05) over time. While CIE a* surface values for redness generally decreased over storage time for all treatments, B maintained more redness. There were few major differences in descriptive sensory evaluation over time, but S and V precluded early onset of rancidity, oxidation and other off-flavors contrary to some of the analytical results. Of consumers tested, 85.6% rated all treatments between like slightly and like very much.

The effects of low atmosphere stunning and deboning time on broiler breast meat quality.

Research was conducted to determine the effect of stunning method (low atmosphere pressure, LAPS, and electrical stunning, ES) and deboning time (0.75 and 4 h) on breast meat quality (n = 576, 144 birds per treatment) in a commercial processing plant. Breast meat quality was evaluated through determining pH, Commission Internationale d'Eclairage L*a*b*, cooking yield, shear force, and consumer acceptability. The onset of rigor mortis was more rapid (P < 0.05) in breast meat from LAPS-stunned birds compared with ES-stunned birds, but no differences existed (P > 0.05) among stunning methods with respect to final pH at 24 h. As expected, breast meat that was deboned at 4 h required less shear force (P < 0.05) to cut through the breast than samples that were deboned at 0.75 h postmortem, but no differences existed between breast meat from LAPS or ES broilers that were deboned at the same time postmortem. However, when samples were marinated with 2% NaCl and 0.5% phosphate, there was no difference in Allo-Kramer shear force between ES 4 h and LAPS 4-h samples, but the ES 0.75-h samples had lower shear force values (P < 0.05) than the LAPS 0.75-h samples. On average, the LAPS 4-h treatment had greater overall acceptability ratings (P < 0.05) than other treatments, and the ES and LAPS 4-h treatments had more acceptable (P < 0.05) texture than the ES and LAPS 0.75-h treatments. Cluster analysis revealed that the 2 largest consumer groups liked all chicken breast fillet treatments, but a larger proportion of consumers liked the 4-h LAPS and ES treatments compared with the 0.75-h LAPS and ES treatments. In addition, consumers who rated baked chicken breast as at least moderately acceptable preferred (P < 0.05) the 4-h LAPS samples over the 4-h ES samples. The present study revealed that both the LAPS and ES systems can be successfully used in commercial poultry plants without detrimental breast fillet quality problems with respect to color, texture, and consumer acceptance.

Sodium chloride concentration affects yield, quality, and sensory acceptability of vacuum-tumbled marinated broiler breast fillets.

The objective of this experiment was to determine the effect of sodium chloride concentration on yield, instrumental quality, and sensory acceptability of broiler breast meat that was vacuum tumbled with a 15% solution (over green weight) for 30 min. Different concentrations (0, 0.25, 0.50, 0.75, 1.00, 1.25, and 1.50%) of NaCl (salt) and 0.35% sodium tripolyphosphate were included in the marinade solution. After marinating, breast fillets were evaluated for marination yields, pH, surface color, cooking loss, tenderness, expressible moisture, proximate composition, purge loss, sodium content, and sensory acceptability. As salt concentration increased, CIE L* decreased linearly, with a concentration of 0.75% having lower (P < 0.05) CIE L* values when compared with the control, 0, and 0.25% NaCl treatments. In addition, there was a linear and quadratic decrease (P < 0.05) in shear force as salt concentration increased, with no further decrease (P < 0.05) when greater than 0.75% NaCl was used. Cooking yield increased (P < 0.05) as the salt concentration increased to 1.0%. All marinated treatments were preferred (P < 0.05) over the control treatment, and all treatments marinated with at least 0.50% sodium chloride had an average rating of like moderately. Cluster analysis indicated that consumer groups varied in their preference of broiler breast meat treatments and that samples that were marinated with between 0.5 to 1.0% NaCl were acceptable to the majority of consumers. Marination with 0.75% NaCl was sufficient to maximize yields and decrease lightness (L*) in vacuum-tumbled, marinated broiler breast that is sold raw, but 1.0% NaCl could be used in a precooked product because it minimizes cook loss. In addition, use of 0.50% NaCl had minimal effects on yields, color, and sensory acceptability when compared with products that were marinated with greater concentrations of NaCl.

Sensory properties and instrumental texture analysis of chevon patties from intact male Boer and Kiko goats harvested at four endpoints.

Intact male Boer and Kiko goats (n=48) were harvested after 0, 4, 8, or 12 weeks on a 16% crude protein concentrate diet. Boneless goat carcass left sides were ground and formed into patties to evaluate cook loss, texture profile analysis, and descriptive sensory characteristics. Increasing feeding duration increased percent fat and decreased moisture in raw ground meat (P<0.05). Boer ground meat had more fat and less moisture than Kiko meat (P<0.05). Breed and feeding duration did not affect cook loss (P>0.05). Increased feeding duration increased aroma intensity and goaty, bloody, musty, and liver/organy aromas; salty, bitter, umami, grassy, goaty, fat, liver/organy, metallic, earthy, and chemical flavors; and juiciness and oiliness, while decreasing chewiness and crumbliness (P<0.05). Boer and Kiko patties had similar sensory properties after 0 and 4weeks on feed, but breeds were more distinguishable after 8 or 12 weeks on feed.

Impact of price and thickness on consumer selection of ribeye, sirloin, and top loin steaks.

Consumers (n=316) were recruited from college football picnickers to select ribeye, sirloin, and top loin steaks from 3 price groups based on thickness (n=10 steaks per price/type combination). Constant weight steaks were assigned to these groups: P1, thinnest, $19.80/kg ribeye and top loin, $10.99/kg sirloin; P2, average thickness, $22.00/kg ribeye and top loin, $13.19/kg sirloin; P3, thickest, $24.21/kg ribeye and top loin, $15.40/kg sirloin. Consumers selected 3 steaks per type and ranked selection criteria (price, color, marbling, thickness, texture). Percentage of steaks chosen from each price group did not differ (P>0.05), but consumers tended to select thinner ribeye steaks (P1 and P2) and thicker sirloin steaks (P2 and P3). Across all steak types, a greater number of consumers reported that marbling, color, and thickness were more important than price and visual texture. Data indicate that consumers may select steaks that display their preferred attributes, even if the steaks cost more.

Effect of alternative salt use on broiler breast meat yields, tenderness, flavor, and sodium concentration.

Fresh chicken breast fillets were marinated with gourmet-style salts: Himalayan pink salt, Sonoma gourmet salt, sel gus de Guerande, and Bolivian rose salt to evaluate their effects on marination and cook loss yields, tenderness, sensory attributes, and sodium concentration. Fresh chicken breast fillets (48-h postmortem) were vacuum tumbled (137 kPa at 20 rpm for 17 min) in a solution of water, salt, and sodium tripolyphosphate at a level of 20% of the meat weights. Instrumental analyses showed no significant difference (P > 0.05) in meat quality with respect to marination yield, cook yield, or shear-force value. There were also no significant differences (P > 0.05) in sensory descriptors between salt treatments. However, Sonoma gourmet salt showed a tendency (P = 0.0693) to score increased savory note values from panelists, whereas Bolivian rose salt received the lowest score. There were no significant differences (P > 0.05) in sodium concentrations between salt treatments, but numerically, sel gus de Guerande had the lowest sodium concentration, which could be important in producing reduced sodium products. Understanding different salts and sodium concentrations allows the poultry industry to use gourmet salts in products and maintain overall meat quality and flavor.
