The present study was conducted to investigate the effects of cut type and ageing period on the technological quality, colour, texture and sensory characteristics of horse meat. Nine different cuts: loin, shoulder chuck roll, shank, outside round, tenderloin, shoulder clod, brisket, top round and striploin from 28-month-old female horses were used in the present investigation. The cuts were randomly assigned into 2, 10, 20 and 30 days’ ageing groups and ageing was carried out in a chilling room (2 ± 2°C). The results showed that there were significant (P < 0.05) differences among the cuts for the drip loss, pH and cooking loss at all ageing days; particularly, striploin had the lowest pH and highest drip loss whereas shoulder chuck roll had the highest pH value. Ageing significantly (P < 0.05) increased in pH and drip loss in most cuts with the highest drip loss ~5.17% in striploin and the highest cooking loss ~9.27% in shoulder chuck roll after 30 days of ageing. At Day 2 of ageing, no differences in Warner–Bratzler shear force values occurred between the cuts (P > 0.05). Ageing only decreased Warner–Bratzler shear force in the loin and outside round (P < 0.05). Colour parameters also revealed differences between cuts and ageing periods, particularly the L* (lightness) values ranged between the cuts from 34.38 to 37.14, 34.0 to 37.24, 33.24 to 37.07, and 34.7 to 38.92 at Days 2, 10, 20 and 30 of ageing, respectively; similarly the a* (redness) values ranged between the cuts from 16.76 to 17.81, 16.61 to 17.85, 17.46 to 19.46, and 17.72 to 20.47 at Days 2, 10, 20 and 30 of ageing, respectively. For the compression, the lowest hardness values (4.41–5.73 kg) were found in tenderloin at all ageing days. Furthermore, the scores for tenderness, flavour, juiciness and acceptability were different (P < 0.05) among the cuts at all ageing days. Ageing improved flavour of loin, shank and striploin, and juiciness of tenderloin and striploin whereas it decreased the juiciness and acceptability scores of some cuts (e.g. shoulder chuck roll). Thus, the present data provide not only useful information for horse meat producers but also important databases for further investigations.

Some meat quality and sensory characteristics were determined of Kıvırcık (n=10), Eşme Kıvırcık (n=10), Karya (n=8) and Çine Çaparı (n=9) lambs in this research. Carcass divided into two parts along the spine and the three different type of muscle samples were taken from the between 8th and 9th vertebrae, 12th and 13th vertebrae and leg part of the left side of the carcasses. Drip loss, cooking loss and shear force values of these muscles were identified. Additionally, pH0, pH24, color, fatty acid composition and sensory properties were determined in M. Longissimus dorsi samples. When muscle types are evaluated separately were a statistically significant factor in terms of dripping and cooking loss and shear force. While the highest dripping loss were reported in M. Longissimus dorsi (3.72%), the highest cooking loss were reported in M. Longissimus thoracis (22.67%) and the highest shear force were reported in M. semitendinosus (4.38 kg). Genotype and muscle interaction were found to be highly significant for only cooking loss. The analysis results for fatty acids indicated that there was an important difference between Kıvırcık, Eşme Kıvırcık, Karya and Çine Çaparı on C10:0, C12:0, C14:0, C15:0, C16:0, tC18:1, CLA, tC18:3, C20:1, C22:0 fatty acids in the study. Genotypes showed no effect to SFA (Saturated fatty acids), MUFA (Monounsaturated fatty acids), PUFA (Polyunsaturated fatty acids) and P/S ratio parameters. Karya lambs performed higher for odor and tenderness, and Kıvırcık lambs showed a higher score for juiciness, flavor and total acceptability in sensory evaluation.

The primary aim of this paper is to determine the influence of two organic production systems, organic grass-fed (OG) and organic concentrate-fed (OC), vs. a conventional concentrate-fed (CC) system; the second aim is to determine the influence of the ageing period on the physical parameters and texture properties of beef from the Retinta breed. Muscle samples from Longissimus thoracis were stored at 2–4 ± 1 °C for 0, 7, 14, and 21 days for the purposes of ageing. Analyses of pH, water losses (drip loss and cooking loss), Warner-Bratzler shear force, texture profile analysis (TPA), and histological analysis of muscle fibre were carried out. The results revealed that organic meat experienced lower drip loss and higher cooking loss than conventional meat. Although the meat of organic grass-fed animals was tougher initially, it showed a higher tenderisation speed in the first ageing days than OC and CC meats. The sarcomere length increased during the ageing period, which showed a negative correlation to shear force. According to its texture characteristics, the Retinta meat produced in organic systems could be recommended by its quality.

Abstract The aim of this study was to analyse the correlation between basic meat composition (water, protein, fat, and connective tissue contents), pH value, and physical parameters (texture and colour, drip loss) of selected beef muscles. Five different muscles (LTH, SEM, SET, PSM, TRI) from 20 carcasses were examined. Measurements of the basic meat composition were conducted using a near infrared spectrometry method, colour parameters in L*a*b system, and texture parameters. Drip loss correlated strongly negatively with the pH value. Depending on the muscle type, the correlation ranged -0.601≤r≤-0.282, whereas drip loss correlated moderately positively with connective tissue content. The most significant positive correlation (r≈0.67) between hardness, tenderness, and fat content was noted in the SEM. Colour parameters strongly depended on pH values (-0.831≤rL*≤-0.338; - 0.828≤ra*≤-0.542; -0.912≤rb*≤-0.719) and to a lesser extent on the content of connective tissue.

A method to improve the physical quality of culled chicken meat is required due to the tough texture and faint color of culled chicken meat. High protein content in culled chicken meat makes it easy to experience quality degradation. One of the methods to maintain the quality of post-harvest chicken meat is using spices. Gelugur acid (Garnicia atroviridis) is a spice for cooking spice, sweets, herbs, deodorizing fresh fish, and even cleansing fish before it proceeds into the processing stage. This study aimed to determine the concentration of Garcinia atroviridis which is effective to improve the physical quality of culled chicken meat. This study used a randomized design with 4 treatments and 5 replications. The treatments consisted of T0: without marination using Garcinia atroviridis (as control), T1: marination in 50 g of Garcinia atroviridis + 1000 mL aquadest, T2: marination in 50 g of Garcinia atroviridis + 750 mL aquadest, T3: marination in 50 g of Garcinia atroviridis + 500 mL aquadest. The parameters were the physical quality of meat consisting of meat pH, water holding capacity, tenderness, cooking loss, drip loss and meat color. Based on the results of the study, Garcinia atroviridis marinade had significant effect (P <0.05) on the pH value of the meat, cooking loss, drip loss, tenderness, water holding capacity, and meat brightness. It was concluded that the marination of meat at concentration of 50 g of Garcinia atroviridis + 1000 mL aquadest (T1) was effective in maintaining the pH value, reducing meat drip loss, increasing water holding capacity, increasing tenderness, brightening the color of the meat and maintaining the freshness of the refined culled chicken meat. Marination of meat in concentration of 50 g Garcinia atroviridis + 750 mL aquadest (T2) was also effective in reducing cooking loss of culled chicken meat.

The polymorphisms of A-FABP gene which associated with meat quality traits of beef cattle divided in five groups(Qingyang native beef cattle group, Pingliang native beef cattle group, Qinchuan beef cattle group, South Devon beef crossbreed group, Simmental beef crossbreed group) in Gansu was studied. Three types of bands defined as genotypes GG, GC and CC were discovered in the study. According to the results we could find the mutation of c. 408 g > c existed in A- FABP gene’s exon3 area by sequencing analysis of gene in three different kinds. The analysis of A-FABP gene polymorphisms associated with meat quality traits like pressing lose, shear force, cooking loss, marbling score, meat color and pH value, showed that pressing loss with genotype GG was significantly greater than genotype CC (P less than 0.05), shear force with genotype GG was significantly greater than genotype GC and genotype CC (P less than 0.01), cooking loss and pH value with genotype GG were significantly greater than genotype GC (P less than 0.05) and genotype CC (P less than 0.01). This mutation of A-FABP gene could be considered as a locus associated with meat quality traits.

AbstractThe aim of the study was to identify the effect of marinating meat on selected quality determinants. Fifty-four pork samples were prepared from longissimus dorsi muscles, each 2.5-cm-thick; they were subsequently marinated for 24 hours (n = 12) and control samples were also prepared (n = 6). The following marinades were used: base marinade (M) whose ingredients included a mixture of herbs and condiments (salt, pepper, juniper berries, rosemary, bay, pimento, garlic) and 3 liquid marinades obtained by adding to the base marinade of apple cider vinegar (MV), light beer (MB) and buttermilk (MM). In the samples pH, marinade absorption, drip loss, cooking loss, WBSF and tenderness by sensory assessment were measured(1,2).The pH value of the material used for the study was 5.8 ± 0.02. The use of the base marinade increased the pH to 6.37 ± 0.03, whereas the liquids used in the marinades decreased the pH to 5.5 ± 0.05. Marination resulted in an increase in the material weight by 2.87 ± 0.05% (MB), 4.45 ± 0.07% (MM), 0.87 ± 0.03% (M). The addition of vinegar resulted in exuding meat juice and a decrease in the material weight by 2.53 ± 0.06% (MV). Using the base marinade reduced drip loss (0.53 ± 0.01%) compared with the control (1.37 ± 0.03%). Sour marinade (MV) increased cooking loss by 18% compared to the control, the MB and MM marinades did not affect this parameter significantly, and the base marinade had a significant effect on reducing cooking loss by 24%. Each of the marinades used had a significant effect on reducing the maximum shear strength by 31% (liquid marinades) and by as much as 46% – base marinade. This relationship was confirmed in a sensory assessment, where higher notes for tenderness were given when base marinade (9.2 ± 0.3pts), marinade with buttermilk (8.1 ± 0.2pts), and marinades with vinegar and beer (7.3 ± 0.3pts) was used compared with control samples (5.7 ± 0.4pts).This study has shown a beneficial effect of the marinades on the tenderness of the products. The most beneficial effect on the quality determinants under study was exerted by the base marinade, which consisted of herbs and condiments only.

Eighty purebred Duroc castrated male pigs slaughtered at 210 days of age were used to evaluate the effect of lean yield (European Union carcass grading based on lean content; or R, O and P classes) on the fatty acid and amino acid composition of raw pork (Day 1 post-mortem), and technological meat quality after vacuum aging up to 4, 6 and 8 days. A strong relationship between slaughter weight and carcass lean-yield was observed. Carcasses graded as having a lower lean yield were fatter with higher intramuscular fat concentration, and differences in proportions of fatty acids with increased monounsaturated fatty acid and decreased polyunsaturated fatty acid percentage, but without adverse effect on ultimate pH, drip loss or colour attributes. There were no effects of carcass lean-yield on amino acid composition of raw pork, with valine being the limiting amino acid relative to lysine by ~30–35%. Vacuum aging did not reduce the shear force of raw pork, which may not be indicative of cooked pork response. The lipid oxidation had an inverse relationship with the polyunsaturated fatty acid content of each pork class, and it did not increase due to vacuum aging up to 8 days. Meat fatness did not affect its amino acid balance and technological quality (colour, drip loss, shear force and lipid stability) but modified intramuscular fat composition.

AbstractThe aim of the study was the evaluation of the effect of ageing on the extent of myofibrillar proteins degradation and tenderness of beef in different crossbreeds, BB × HF and SM × HF, from which themusculus semitendinosuswas obtained. The pH value, basic composition of meat, and colour parameters were determined on the 3rddpost mortem. The Warner Bratzler shear force and the extent of protein degradation were evaluated in regard to the effect of ageing time. Meat of BB × HF crossbreed had a lower amount of intramuscular fat and higher protein content (P ≤ 0.05). The shear force decreased with ageing time in the case of both crossbreeds. However, the highest values were noted in SM × HF crossbreed on days 3 and 7 of ageing. The differences in proteolysis of myofibrillar proteins and polypeptides, determined by SDS-PAGE electrophoresis, were observed between crossbreeds and the ageing time. A significant decrease in desmin and increased levels of 49-46 kDa and 32-27 kDa polypeptides (products of proteolytic degradation) were observed with an increasing ageing time. In addition, the rate of increase in the amount of 32-27 kDa polypeptides was more significant in BB × HF crossbreed. The data obtained showed that tenderness and the extent of protein degradation are associated with ageing process and animals’ genotype.

The Relationship

The relationship between objective measurements (shear force, compression, drip loss, cooking loss) and sensory evaluation of tenderness and juiciness of samples of M. longissimus thoracis et lumborum was examined using data from 2 experiments which imposed different electrical stimulation and aging treatments post mortem, with resultant differences in sensory and objective measures of tenderness. The relationships were tested first in separate models for each objective measurement, and then in multiple regressions containing all measurements. These models were then repeated with the inclusion of stimulation and aging treatments and their interactions with each objective measurement. Shear force by itself was a useful predictor of sensory tenderness score, with which it had a quadratic relationship. Compression and cooking loss, when used by themselves, accounted for substantially less variation in sensory tenderness scores than did shear force, with larger residual standard deviations (r.s.d.). Drip loss had no significant relationship with sensory tenderness scores. Inclusion of post-slaughter treatment in the analyses increased the amount of variation in sensory tenderness scores accounted for by only a small amount in the case of shear force, with a substantial increase in the case of compression and cooking loss. Use of all objective measurements in the 1 model had a similar predictive ability (r2 , r.s.d.) as the use of shear force plus treatment variables. Aging affected the sensory tenderness scores given by taste panellists, in that they gave 14-day aged meat higher tenderness scores (more tender) than they gave 1-day aged meat with the same shear force, compression or cooking loss values. Electrical stimulation did not affect the relationship between sensory tenderness scores and shear force, but did affect that between sensory scores and compression. The effect was similar to that seen for aged meat, with stimulated meat being scored as more tender by a taste panel than non-stimulated meat, at the same compression values. Post-slaughter treatment did not affect the slope of these relationships. When all objective measurements were analysed together, aging period affected the relationship between tenderness scores and objective measures, with tenderness scores being lower in 1-day aged samples than 14-day aged samples at the same combination of objective measures. There was only a poor relationship between shear force, compression, drip loss, cooking loss and sensory juiciness scores.
