The aim of the study was to analyse the effect of sex, storage time and muscle type (m. longissimus dorsi and m. biceps femoris) on quality traits of the meat of French Lop rabbits. The muscles were obtained from 12 males and 12 females slaughtered at the age of 90 days. The characteristics analysed included pH, colour parameters, water holding capacity and proximate composition. No effect of sex or muscle type was found (P>0.05) on the pH of the meat in any of the periods analysed. The storage time differentiated (P≤0.01) between pH45min and pH24h and between pH45min and pH7days. None of the colour parameters was influenced by sex (P>0.05), but they were significantly affected by storage time (P≤0.01). Redness and yellowness were also influenced by the type of muscle (P≤0.01). The rabbit meat stored for 7 days was characterised by higher drip loss than the meat stored for 24 hours (1.31-1.49% vs. 3.34-3.57%, P≤0.05). The m. biceps femoris of both sexes had a greater capacity to hold water as measured by the pressure method than m. longissimus dorsi (P≤0.01). There was no effect of sex or muscle type (P>0.05) on the level of cooking loss. Sex and muscle type also had no influence (P>0.05) on the proximate composition of French Lop meat.

Abstract. This study was conducted to determine the effect of genotype and fattening system on carcass measurements of lambs and technological properties of the male lamb meat (Musculus longissimus dorsi, MLD). The animal material in the study included 39 Hemşin (H) and 39 Tuj (T) male lambs. Extensive (E), semi-intensive (SI) and intensive (I) fattening systems were applied in the study, which was completed within 90 d. In the E, SI and I fattening groups, a total of 48 lambs, including 16 lambs in each group, were slaughtered. The results of the study indicated that the effect of genotype on the first-hour yellowness (b*), being one of the colour parameters of the MLD, and the effect of the fattening system on 1 h hour redness (a*) and chroma (C*), being among the colour parameters, were statistically significant (P<0.05). The effect of genotype and fattening system on MLD pH at 45 min (pH45 min) and 24 h (pH24 h) after the slaughtering and on the third and seventh hour drip loss (DL %) was statistically nonsignificant (P>0.05). The effect of genotype and fattening system on DL, cooking loss (CL %) and texture (TT) was nonsignificant (P>0.05), whereas the effect of these factors on water-holding capacity (WHC %) was significant (P<0.05). The effect of genotype on external carcass length (ECL), internal carcass length (ICL), internal hindquarter length (IHL), and carcass and leg conformation was statistically significant (P<0.05). The effect of the fattening system on all the carcass measurements except for carcass conformation, carcass depth (CD) and external chest width (ECW) was statistically significant (P<0.05). Genotype and fattening system affected the colour and some quality traits of meat and carcass measurements of lambs.

The aim of the research study was to evaluate the effects of a common culinary spice such as garlic powder and salt addition on the quality and microbial shelf life of rabbit meat burgers. Rabbit burgers were evaluated for pH, the colour parameters, the water holding capacity and microbial loads during storage time of seven days at 4 °C. Four different formulations of burgers (n = 180 in total) were tested as control samples (only meat, C), burgers with garlic powder (at 0.25%, G), burgers with salt (at 1.00%, S) and burgers with both garlic powder and salt (0.25% and 1.00%, respectively, GS). As results, it was highlighted that garlic powder and salt addition significant affected pH, water holding capacity and some colour parameters of burgers. In particular, salt affected the pH of the raw burgers, leading to lower values that partially influenced all the colour parameters with higher a* values of S burgers. The mix of garlic powder and salt (GS burgers) showed mixed effects even if more closed to the G burgers than S ones. Salt expressed its properties of binding water molecules reducing drip and cooking losses in S and GS burgers. No variations in microbial loads were highlighted in relation to the formulations. Storage time affected all the parameters, highlighting a deterioration of the burgers’ quality and an increase of the microbial loads.

Abstract. A study based on 150 carcasses of rabbit crosses of three breeds: Flemish Giant (FG), New Zealand White (NZW) and Californian (CAL) was conducted to determine the changes that occur within the first 24 h post mortem in the meat color parameters, i.e. lightness (L*), redness (a*), yellowness (b*), chroma (C*) and hue (H*), in the rabbits of different genetic groups and sexes. Four groups were formed: FN (FG bucks×NZW does); FC (FG bucks×CAL does); FN×C (FN bucks×CAL does); FN×FN (FN bucks×FN does). Meat colour was measured on the surface of Longissimus dorsi (LD) and biceps femoris (BF), 45 min and 24 h post mortem. The genetic groups differed significantly in the meat colour parameters of the LD and BF muscles at both times after slaughter. After 24 h, a* and b* values of the LD muscle were highest in FC group (18.05 and 6.65, respectively) and the lowest in FN×FN group (16.46 and 4.75, respectively). The greatest color difference (ΔE) of the LD muscle was in FN×FN rabbits (9.85) and the smallest in FC group (5.07). The differences between genetic group in color parameters of the BF muscle were smaller but significant, which indicates that crossbreeding may be used in practice to change meat color. Sex did not influence significantly the color parameters of the muscles at either time, although the a* and C* values of the BF muscle were higher in males than females.

Abstract Tenderness is usually associated with the proteolysis occurring in muscles. However, most of the studies concentrate on one muscle only. The aim of this study was to describe the changes in myofibrillar protein percentage proportions during the ageing of 8 bovine muscles. Investigations were conducted on the muscles from different parts of the carcass, from the forequarter: m. pectoralis profundus, m. infraspinatus, m. triceps brachii, m. serratus ventralis, and from the hindquarter: m. biceps femoris, m. semimembranosus, m. semitendinosus and m. longissimus dorsi (thoracis et lumborum). The effect of muscle type was significant for all parameters except for percentage proportions of titin (3000÷3700 kDa), MHC (205 kDa) and protein fractions between <205÷42> kDa. Differences between the muscles varied depending on the analysed proteins and the time of storage. A significant effect of ageing time for titin, nebulin (approx. 800 kDa), proteins of molecular weight of 38 kDa, proteins smaller than 42 kDa and in the range of 3000÷205 kDa, 205÷42 kDa and 38÷20 kDa was observed. The decrease of percentage proportions of titin, nebulin and proteins in the range of 3000÷205 kDa and an increase of protein bands in the range of 38÷20 kDa and proteins below 42 kDa was also observed. During the storage period of beef from the 2nd to the 14th day, the progress of myofibrillar proteolysis was different in each muscle. The changes of tenderness were not related to shear force values. It is probable that the changes in other constituents of meat might influence the tenderness more than those in myofibrillar proteins.

<p class="Articletitle">The effect of sorghum hydrolysed by <em>Trametes maxima</em> CU1 and <em>Pycnoporus sanguineus</em> CS2 was evaluated on growth performance traits and rabbit meat quality. A total of 24 unsexed New Zealand rabbits, weaned at 20 d of age, were allocated to 2 treatments: T1 (diet including 300 g/kg of non-hydrolysed sorghum) and T2 (diet including 300 g/kg of hydrolysed sorghum by <em>Trametes maxima</em> CU1 and <em>Pycnoporus sanguineus</em> CS2). Rabbits of group T2 did not have significantly different (<em>P</em>&gt;0.05) feed intake compared to those in T1. Carcass traits were also not significantly different (<em>P</em>&gt;0.05) between the 2 groups. The pH, water-holding capacity, colour and cooking loss of the longissimus lumborum were not different (<em>P</em>&gt;0.05) between treatments, whereas the pH of the rabbits biceps femoris was higher in T2 (6.21; <em>P</em>&lt;0.05) than in T1 (6.14). Meat hardness and gumminess in T2 were lower (<em>P</em>&lt;0.05) in comparison to meat from T1. Thus, sorghum hydrolysed by <em>Trametes maxima</em> CU1 and <em>Pycnoporus sanguineus</em> CS2 contributed to a better rabbit meat texture.</p>

Gelling properties stability of the Maillard-type and dry-heating egg white proteins (MEW and DEW) were investigated. MEW were prepared by storing sugar-preserved egg white proteins and glucose at 60 °C and 79% relative humidity for 2 days, and DEW were prepared by storing at 80°C in dry state (7.5% moisture content) for 7 days. The results showed that both MEW and DEW have excellent gelling properties. After storage at room temperature for 180 days, gel hardness, spring and cohesiveness of MEW increased by 1.92%, 1.89% and 4.24% respectively, water holding capacity of MEW gel decreased by 1.42%, while storage time had a considerable effect on those of DEW gels. A tight and more uniform network with constant stability in the course of storage was observed in the gel of MEW (500×), while gaps in EWP gel network were larger and the gel texture became looser with storage time. The results demonstrated that gelling properties stability of MEW is better than DEW.

Resumo Neste trabalho, foram avaliados os comportamentos mecânico e estrutural de diferentes cortes cárneos em testes de determinação da força de cisalhamento, com o objetivo de identificar possíveis diferenças que podem interferir negativamente na mensuração da maciez objetiva. Seis cortes cárneos: Contrafilé (Longissimus dorsi), Maminha (Tensor fasciae latae), Lagarto (Semitendinosus), Filé-mignon (Psoas major) e Picanha (Biceps femoris) bovinos, e Lombo suíno (Longissimus dorsi) foram analisados de acordo com o método Warner-Bratzler, usando um texturômetro equipado com lâmina de 1 mm de espessura. As superfícies cisalhadas foram analisadas por microscopia eletrônica de varredura e as curvas mecânicas geradas durante os testes foram estudadas. Diferentes comportamentos foram observados nas curvas mecânicas e na microestrutura dos cortes cárneos em estudo. Alguns cortes apresentaram picos máximos bem definidos, enquanto outros apresentaram curvas mais abertas com maior distribuição da força durante os testes. Os cortes também apresentaram diferenças quanto à altura dos picos, que variou entre diferentes cortes e até em um mesmo corte. Nas microestruturas, foram observados diferentes comportamentos como: fibras deformadas por tracionamento, fibras aglomeradas devido a forte compressão e irregularidades na espessura e formato de fibras. Assim, concluiu-se que o teste de determinação da força de cisalhamento utilizado envolve outros princípios, como compressão e elongação, dependendo do corte cárneo estudado.

AbstractThe meat palatability, water-holding capacity, colour and shear force values of 32 Boer goat (BG) kids and 32 South African Mutton Merino (MM) lambs were investigated. Two pelleted diets (offered to 16 animals per species) with either a low (LE, 9·9 MJ/kg dry matter (DM)) or a high (HE, 12·1 MJ/kg DM) metabolizable energy level were given to the animals for either 28 or 56 days. Thereafter the animals were slaughtered, the meat cooked and presented to a trained sensory panel. Organoleptically, a difference between goat and lamb was noted. Each one had a specific species flavour, which was not influenced by energy level of the diet. BG meat was perceived to be stringier than that of the MM, but there was no significant difference in Warner-Bratzler shear force values. Tenderness declined with age in both species and there was also a tendency for goat meat to be less juicy than lamb. Chevon had a more pronounced after-taste than lamb. No objective difference could be distinguished between the colour of the cooked goat and lamb, but there was a tendency for fresh lamb to have a higher a*-value (redness) than goat. Although diet did not influence drip loss, drip loss increased with an increase in slaughter age. Only after 56 days did the m. semimembranosus of MM have a significantly higher drip loss than that of BG (LE: 4·84 v. 3·43%; HE: 4·72 v. 3·23%). In the m. semimembranosus of both species cooking loss increased with an increase in slaughter age. It can be concluded that goat meat compares favourably with lamb in terms of water-holding capacity, colour and shear force values. If goats are finished in the feedlot, it can be done on a LE diet, since diet does not influences any of the mentioned characteristics. This may render a direct economic advantage for BG feedlot finishing.
