Water Holding

This study investigated the CIELab colour, water holding capacity, texture and oxidative stability of sheep meat from different breeds, finishing feeds, and retail packaging methods. Leg primal cuts from a subset of Composite wether lambs (n = 21) and Merino wether yearlings (n = 21) finished on a standard diet containing grain and cereal hay, a standard diet with camelina forage, or a standard diet with camelina meal, were used in this study. Semimembranosus and Vastus lateralis were packaged in vacuum skin packaging (VSP), or modified atmosphere packaging with 80% O2 and 20% CO2 (HioxMAP), or with 50% O2, 30% N2, and 20% CO2 (TrigasMAP). Packaging had a greater effect (p < 0.001) on L*, a*, b*, hue, and chroma than the effects from breed and finishing feed. Purge loss was affected by packaging. Cooking loss was affected by breed for Semimembranosus and packaging for both muscle types. HioxMAP and TrigasMAP increased WBSF and Texture Profile Analysis hardness of the meat compared to VSP. Lipid oxidation, assessed by TBARS, were lower in camelina forage or camelina meal supplemented diets and TrigasMAP compared to standard diet and HioxMAP, respectively. Total carbonyl and free thiol content were lower in VSP. Thus, supplementing feed with camelina forage or meal and lowering oxygen content in retail packaging by TrigasMAP or VSP are recommended to ensure optimal sheep meat quality.

Tian, J.-C., Han, L., Yu, Q.-L., Shi, X.-X. and Wang, W.-T. 2013. Changes in tenderness and cathepsins activity during post mortem ageing of yak meat. Can. J. Anim. Sci. 93: 321–328. Very little research has been conducted on yak meat tenderization. In this study we investigated the changes in physical characteristics (e.g., pH, water-holding capacity, texture profile analysis, shear force) and cathepsins L, B and H activities in the tenderization process. These traits were quantified in longissimus dorsi muscle from 10 yaks during 192 h post mortem. Samples were aged at 4°C for 0, 12, 24, 36, 48, 72, 120, 168 and 192 h. pH decreased (P<0.05) from 6.84 to 5.54 in the first 72 h and did not change significantly during the next 120 h. Water-holding capacity showed an overall decreasing trend (P<0.05). Shear force decreased? (P<0.05) and myofibrillar fragmentation index increased? (P<0.05), and it was concluded that ageing can improve yak meat tenderness. Our results on texture profile analysis showed a decrease in hardness (P<0.05), springiness (P<0.05) and chewiness (P<0.05), reflected in a progressive softening during ageing (P<0.05). Cathepsins L, B and H activity showed an increased trend (P<0.05). In conclusion, our results show potential roles for cathepsins L, B and H in the tenderization process. This study provides further insights into the tenderization process of yak meat, which may ultimately be used for the advantageous manipulation of the process.

Different Levels

This study assessed the effects of Methylcellulose (MC) at different concentrations on plant-based meat analog (PBMA) patties, comprised of commercial texture vegetable protein (C-TVP) and textured isolate soy protein (T-ISP) as key ingredients, and compared to beef patty control. A significantly higher difference was observed in moisture content in control with increasing MC concentration than the C-TVP and T-ISP patties. However, protein varied significantly among three different protein sources, with control had higher protein content than PBMA patties. Crude fiber content recorded higher values in C-TVP as compared to control. Significantly lower pH values were recorded in control than C-TVP and T-ISP respectively. Regardless, with the addition of MC or ingredient PBMA and control patties tend to reduce lightness (L*) and redness (a*) value after cooking. Although control sample before cooking exhibits lighter and redder than PBMA patties (C-TVP and T-ISP). Likewise, water holding capacity (WHC) decreases as the concentration of MC increases (1.5–4%) in control and PBMA patties. Warner-Bratzler shear force (WBSF) and texture profile analysis (TPA), including hardness, chewiness, and gumminess of control, were significantly higher than C-TVP and T-ISP. Consequently, panelists’ in the sensory analysis presented that C-TVP patties containing 3% of MC had better sensory properties than T-ISP. Hence, PBMA patties with C-TVP and incorporation of 3% MC are considered ideal for manufacturing of meat analog as related to control (beef).

Fifteen Pirenaica (beef) heifers and fifteen Holstein-Friesian (dairy) heifers were compared to consider the effect of intended purpose of the breed on meat quality. Animals were slaughtered at around 12.4 mo of age. Carcass weight was 247.6 kg for Pirenaica and 229.2 kg for Holstein-Friesian heifers. pH24hours, moisture, fat, protein, ash, water holding capacity, CIE L*a*b* and C* and H* values, collagen content, and shear force were determined in longissimus dorsi muscle. Sensory analysis of meat was performed to obtain the texture profile, scored by a trained taste panel. Sensorial differences of meat were mainly in relation to higher fat content observed in Holstein-Friesian (2.87%) vs. Pirenaica breed (1.82%) (P<0.01). Total and soluble collagen contents for the two breeds differed (P<0.01 and P<0.05, respectively) but did not result in different meat tenderness scores by taste panelists. Higher water-holding capacity in meat of Holstein-Friesian was observed (P<0.01). CIE L*a*b*, coordinates C* and H* values were not different between breeds. Sustained juiciness and oiliness were higher in Holstein-Friesian than Pirenaica (P<0.05 and P<0.01, respectively). Results suggest that beef characteristics of young heifers of dairy and beef breeds are similar with the exception of characteristics related to juiciness.

The purpose of this study was to investigate the effect of papaya leaves crude extract on the physicochemical properties of marinated chicken meat. Papaya leaves was extracted with sodium acetate (CH3COONa) buffer (pH 7.2) at room temperature. Protein concentration and activity of enzyme in the crude extract were determined by using UV-Spectrophotometer. The crude extract was mixed with marinated ingredients and then coated onto chicken meat which was subsequently kept for overnight in refrigerator at chill temperature. Protein concentration of the enzyme was identified as 166.36 μg/μl and enzyme activity was 1.28 CDU/ml. Results also showed that lightness (L*), cooking loss and shrinkage of the marinated chicken were higher than control. Redness (a*), yellowness (b*), protein content, water-holding capacity, shear force, and texture profile analysis were lower than control. Microstructure analysis showed that the chicken meat muscle was destructed in the presence of papaya crude extract. Sensory acceptability evaluation of marinated chicken which was carried out by using 9 point hedonic scale suggested that chicken meat treated with papaya crude extract gave significant effect on texture, juiciness, flavour and overall acceptability compared to commercial bromelain. Additionally, the use of papaya crude extract gave a significant effect on the physicochemical properties of marinated chicken.

Dagger-tooth pike conger fish (Muraenesox cinerus) is known to have high edible portions and white meat, thus can be used as a surimi raw materials. However, the textural quality of this fish meat is relatively poor after washing process of surimi. This reserch was aimed to analyze the effects of TGase activator and STPP addition to increase the textural quality of surimi malong. The method used is a factorial experiment with the addition of activator TGase 0.2; 0.4 and 0.6 and STPP at concentrations 0; 0.2; 0.5 and 0.8. Parameters observed were texture profile analysis (TPA), water holding capacity (WHC) folding test, bite test, and scanning electron microscopy (SEM). The results showed that the addition of STPP and activator TGase (Ca) has significant effect on increasing the hardness, fracturability, chewiness, gumminess, bite test and the folding test. Furthermore, microscopies structure (SEM) of malong surimi showed smooth and solid surfaces.

Potato protein isolate (PPI), a commercial by-product of the starch industry, is a promising novel protein for food applications with limited information regarding its techno-functionality. This research focused on the formation of both thermal and high-pressure gels at acidic and neutral pH levels. Our results reveal that physical gels are formed after 30 min by heat at pH 7 and pH 3, while pressure (300–500 MPa) allows the formation of physical gels only at pH 3, and only when the system crosses 30 °C by adiabatic heating during pressurization. Texture profile analysis (TPA) revealed that gel hardness increased with both gelation temperature and pressure, while water-holding capacity was lower for the pressure-induced gels. The proteins released in the water-holding test suggested only partial involvement of patatin in the gel formation. Vitamin C as a model for a thermally liable compound verified the expected better conservation of such compounds in a pressure-induced gel compared to a thermal one of similar textural properties, presenting a possible advantage for pressure-induced gelation.

The objective of this study was to recognize the specificity of microstructural changes of DFD sheep m. Longissimus dorsi during its ripening, and to try to explain them by biochemical and physicochemical amendments of meat. The fresh (4 h post mortem) DFD sheep m. Longissimus dorsi with pH1 = 6.95 stored at 2 ± 2°C was used. The microstructure, degree of proteolysis, color properties, water holding capacity and pH of DFD sheep meat were evaluated during 5d of storage. The shortenings of the sarcomeres and typical alternation of light and dark bands were established after 48h storage of DFD sheep muscles. Simultaneously, pH and water holding capacity decreased with 16.5% and 50.6% resp. (p ≤ 0.05), accompanied with the lowest protein solubility, and a disappearance of myosin heavy chains. On the 3d post mortem sarcomeres were partly regenerated and their native structure was recovered, A- and I-disks were visible, and Z-lines were undamaged. On the 4d post mortem was found large gap formation in sarcomeres and difficulty recognizable A- and I-disks. On the 5d post mortem the pH and water holding capacity were similar (p > 0.05) with the initial values but free amino nitrogen decreased with 34.5%.

Background: The increasing awareness on the nutritional and medicinal value of button mushroom is the guiding light for the increased production and consumption of mushroom across the world. Due to its perishable nature it cannot be stored for long period. Different methods are used for increasing mushroom post-harvest shelf life which includes chemical treatments, low temperature storage conditions, modified atmosphere packaging (MAP) and use of thick packaging material. Methods: Button mushroom were chemically treated with CaCl2 (2.5% w/v), citric acid (3% w/v) and sorbitol (0.1% w/v) which was followed by packaging in polyethylene film under three different MAP compositions and stored at 8oC temperature for further studies. Physico-chemical and texture profile analysis were done for 16 days at interval of four days. Result: Significant changes were obtained in three different MAP treatments. MAP composition with 6% O2 and 12%CO2 were found best for post-harvest storage of button mushroom. Blanched samples without chemical treatments and packed under ambient conditions were spoiled after 16 days as compared to chemically treated samples stored in MAP packaging.
