In: Nollet, L.M.L., Toldra, F. This study aimed to evaluate inclusion of green tea leaves (Camelia sinensis) powder (GTP) into lamb sausage on physicochemical properties, total microbes, oxidative stability, and sensory quality. Encyclopedia of Meat Sciences 2e, V. © 2014 Elsevier Ltd. All rights reserved. The drainable porosity controls the transient water-table dynamic that often develops at the soil–bedrock … decline was 0.13 pH units less for meat that was marinated. Ten replicates at each time, point. 11 0 obj This study was conducted to determine the effect of genotype and age at slaughter (8, 14 and 22 months) on the retail display life of lamb chops [boneless loin (M. longissimus thoracis) and boneless leg steaks from the knuckle (M. rectus femoris)]. soil structure affects root growth Improved infiltration Low infiltration. solubility can be determined by subjecting the pellet left, after centrifugation of the low ionic strength solution, to a, high ionic strength buffer in order to solubilize the myo-, cooked meat products. Report field capacity, permanent wilting point and available water content (%) (on an oven-dry basis) to one decimal place. Reproduced from Kristensen, L., Purslow, P.P., 2001. The second test determines how much water the soil holds when plant roots can no longer extract water (wilting point). The effect of ageing on the water-holding, capacity of pork: Role of cytoskeletal proteins. This usually takes place 2–3 days after rain or irrigation in pervious soils of uniform structure and texture. Three lambs aged one year was slaughtered as sausage meat source. Thus, samples des-, tined for objective measurement of cooked meat are, weighed before cooking, and then after cooking, the sam-. The relationship between post-mortem traits of muscle proteins and water loss traits was investigated using 84 pork loins representing the four quality traits of PSE, RSE (reddishpink, soft, exudative), RFN (reddish-pink, firm, non-exudative) and DFD. Incorporation of 0.0%, 1.0%, 1.5%, and 2.0% GTP to lamb sausage during 0, 7, and 14 days of storage was conducted in a completely randomized design of ANOVA with five replications in each treatment. llustration of the rapid filter method for measuring weep or exudate on a beef loin surface. Isobetic, the reduced pigments. Finally, methods for measuring WHC are defined and conclusions and future trends are given. The water holding capacity of the soil is determined by the amount of water held in the soil sample vs. the dry weight of the sample. However, GTP was also ineffective at improving the sensory quality of the sausage. This method removes more, water than most of the other methods, due to the high, centrifugal forces involved. The ratio of percentage re. Abbott, TS (ed) 1985, Soil Testing Service: Methods and Interpretation . EI and EE were characterised by evaluating total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity (AA). to monitor the change in the pigments in the meat surface during retail display. Scan 4500 XE Plus; the size of the measuring head (large, chroma/saturation, is one of the two main systems generally, used to describe the color of fresh meat. We speculate that the NIR models may be sensitive to the accumulation of free water arising from the degradation of cytoskeletal proteins during ageing, releasing the water normally tightly bound up in the tertiary protein structures. This review presents an integromics of recent muscle proteomic studies to investigate pathways and mechanisms of beef colour. the lowest fat content and the presence of AB increased the oxidative stability. endobj TBARS were analysed in the raw ground pork with EI (MEI) and EE (MEE) as well as meat without EI and EE as the control (CTL) and sodium ascorbate (NaASC) as positive control. The property of the soil that permits the flow of water through its voids with ease is known as permeability. 467, Trout, G., 1988.

The first test run on the soil determines the amount of water the soil can hold at field capacity. This study opens the possibility of using GlcN in meat products to increase oxy- and deoxymyoglobin and enhance the color of meat. Open circles: nonglued samples. acceptability of meat on retail shelves when it is purchased. Bars indicate the standard error of the mean. • The soil tension where crops begin to stress – for sugarcane this is about -100 kPa. The changes in structure as a result of cooking and also processing are presented as well as the influence of high pressure processing, salting pre- and post-rigor, ionic strength, phosphates and marination. CIE L* (lightness), a* (redness) and b* (yellowness) values, ... After prolonged storage, HiOxMAP packaging produced the palest colour samples and this was significantly different after 7 and 14 days of storage (p < 0.05). AB 10% and AB 15% had good overall liking and were sensorially characterized as juicy, tender and tasty burgers. Three specific areas were discussed in order to develop internationally accepted reference methods: In the autumn of 1997 the methods were brought into their final form at the Meat Industry Research Institute of New Zealand (MIRINZ). Green tea leaves as a source of natural antioxidants has a huge potential to improve sausage quality from lamb meat, in line with an increase of people concern in functional food products. PDF | On Jan 1, 2003, Thomas G Huntington published Available Water Capacity and Soil Organic Matter | Find, read and cite all the research you need on ResearchGate Most of the samples belong to finer texture in lower elevation and reverse in higher elevation. Background The phenolic compounds present were identified using ultra-high performance liquid chromatography-quadrupole time-of-flight (UHPLC-qTOF). Four treatments were compared: control (0% AB, 20% fat) and 3 treatments with partial fat replacement: AB 5% (5% AB, 15% fat); AB 10% (10% AB, 10% fat); AB 15% (AB 15%, 5% fat). NSW Department of Agriculture. Soil Texture - is the relative proportions of various sized particles in the profile. SDS-PAGE of extracted and unextracted myofibrils showed that the reduced myofibrillar solubility of PSE samples was caused by decreased extractability of the myosin heavy chain in these samples. Application of sorghum bran and phenolic compounds for meat preservation and quality(started). The cone cells, (photoreceptors) in the eye have sensitivity peaks in three, wavelengths: short, medium, and long, hence tristimulus refers. In conclusion, epazote has potential as a natural antioxidant in meat and meat products. stream The meat samples with EFT showed significant differences (p < .05) in color (CIE L*a*b*) and exhibited lower TBARS values compared with those without EFT. Bulletin National Institute of Animal Industry 29, 69. Quantification of the CEC is an essential yet challenging task. velopment and processing optimisation(started) Thirty swine halves, of the commercial classification U, were divided into six experimental groups and chilled under varying conditions over a period of 20 h. Three of the experimental groups were sprayed periodically with 810 g drinking water, This study investigated effects of time post-mortem on development of pink discoloration in turkey Pectoralis major muscles. Significantly higher a* value in grilling had indicated that more myoglobin degradation occurred during boiling, frying and roasting. machines were produced by Minolta, which enabled easy. endobj OEO and RES emulsion/nanoemulsions were prepared and showed good stability at 4 °C for 15 days. Thus, for irrigation purposes, a “maximum allowable The colour and retail shelf-life of lamb cuts were assessed objectively, using a HunterLab Miniscan, at 24 h postslaughter and at 0, 2 (midpoint of commercial retail display life) and 4 (endpoint of commercial retail display life) days for overwrapped product in a simulated retail display. endobj :��Br*( <>>> The oxy/met ratio declined from 2.3 to 1.7 between days 3 and 14 of display in HiOxMAP samples (p < 0.05), whereas the ratio was similar and stayed relatively high for VAC samples. Reproduced with permission from Robyn Warner, Department of Primary Industries, Victoria, Australia. endobj quality, and sensory acceptability when the meat is consumed, possibly justifying the visual impact. Pork loins (n = 40) were cut and stored under two packaging methods (HiOxMAP, 80% O 2 , 20% CO 2 ; VAC) for up to 14 days, with samples taken at various times for measurements. New, Kauffman, R.G., Eikelenboom, G., Van der Wal, P.G., 1986. Drainable porosity of a soil is defined as the water content between field capacity and saturation. The genotypes represented were Poll Dorset × Border Leicester Merino, Poll Dorset × Merino, Merino × Merino (M × M) and Border Leicester × Merino. humintech.com. muscle. The spraying had no influence on the colour of the spinal spongiosa. The water holding capacity (WHC) of a soil is of great value to terrestrial ecosystem as it provides a simple means of determining moisture contents required in soils for good plant growth [14]. This method is no longer widely used as, lter paper method: This method relies on capillary. including the use of phosphates and salts. The use of vacuum packing for retail shelves, should be considered as the preferred option, over HiOxMAP. Thus, geometries can be diffuse, etry machines are recommended for meat as they exclude, ditions. Sorghum bran tea de, Visible spectra of cold stored, cooked, and diseased chicken meats were collected. When incident light strikes a surface, the re, faces, they will be perceived as a different color. <> Key findings and conclusions This disc allows moisture to, spin down to the bottom while leaving the tissue on the, the problems with this method, which has introduced in-, accuracies in the results, has been the blocking of the pores, in the membrane. The most commonly used, method involves using a standard size and weight block, a tray, so that all the drip can be collected in the bottom, of a tray, which is not in physical contact, end, and the drip loss is expressed as a loss in weight of, centage of the initial weight. The appearance of weep or purge is un-, loss, involving suspension of a meat sample in an in, 3. stream After 7 days of storage, HiOxMAP samples exhibited inferior consumer acceptability for tenderness, flavor, overall liking, quality and re-purchase intention as well as higher shear force and hardness, relative to VAC samples (p < 0.05 for all). Lipid oxidation values, measured using thiobarbituric acid reactive substances, in HiOxMAP pork loins, were higher at all time points compared to VAC during the 14 day storage period (p < 0.05). Soil texture and organic matter are the key components that determine soil water holding capacity. Credit: Athula, N., Department of Primary Industries, VIC, Australia. Modelling of the formation of pale, soft, and exudative meat: Effects, of chilling regime and rate and extent of glycolysis. 3 0 obj This review identifies six pathways involved in beef colour including energy metabolism, heat shock and oxidative stress, myofibril structure, signalling, proteolysis and apoptosis. EI showed higher TPC and TFC while EE showed a higher percentage of some phenolic compounds, but AA was the same for both samples. An example of this is when color. �N�=�Q9DEA�C.9�CD. Different machines, different versions of machines and variation in the aperture size can influence the colour measurements obtained, ... storage, processing, and cooking (Hamm, 1986). Honikel, K.O., 2009. It is used quite often; it appeared in at least 64 abstracts of papers It would be important to know the structure of the soil for agriculture, construction, and transportation industries. holding characteristics determined in 26 the laboratory with the field capacity as measured in the field, were made to establish the relationships between them for the soils under test. The aim of this study was to develop an edible alginate‐based film produced with turmeric (EFT), as an active compound, and evaluate its antioxidant capacity for application in fresh pork loin, beef loin, and chicken breast. Laboratory machines have been used for a, 700 nm of lamb loin muscle overwrapped and under simulated retail display for 0 or 3 days. which has been displayed for 0 or 3 days. 2. In, particular, cooking loss can have quite different in, factors and thus should not be inferred from measurements of, Weight loss during storage, cooking, freezing, and thawing, are related to how much water is available and how easily it, Methods to Measure Water-holding Capacity, The measurement of WHC usually involves the application of, force to measure the water released. Meat Science 58, 17–23. AB incorporation affected texture, resulting in less hard and less chewy products. An increase in lightness is attributed to relative contents of chemical forms of myoglobin and increased light scattering due to protein denaturation, ... At 7 days storage, the oxy/met ratio of HiOxMAP meat was lower than VACb, and was lower than both VACb and VACnb after 14 days of storage (p < 0.001). Protein solubility measurements (sarcoplasmic, myofibrillar and total) were lower and myosin denaturation (quantified by myofibrillar ATPase activity) was higher for PSE samples compared with samples from the other quality classes. Furthermore applying Humate to a soil increases the water holding capacity and the formation of certain enzymes, that increases the plant's resistance to stress, coming from transplanting, temperature extremes or drought. Annex A Recommended method for measuring the water-holding capacity of the soil. Water loss from meat samples (centrifugal loss %), brillar protein solubility is determined by the difference, ned internal temperature, cooled, and then weighed for, lter paper method) and temperature at pH 6 (rigor temperature) in the beef loin, to detectors (human or machine). The water-holding capacity (WHC) of pork decreases post-mortem but has been shown to increase during subsequent ageing. The “available water holding capacity” (AWHC) is determined by multiplying the PAW by the root zone depth where water extraction occurs. RSE samples were similar to RFN samples in protein solubility and myosin denaturation, although RSE had lower values then DFD samples for protein solubility measurements. When glucosone (250–2000 mg/L) was incubated with myoglobin it contributed to the formation of deoxymyoglobin, indicating its capacity to reduce metmyoglobin. Moisture and water-holding capacity. Boca Raton, FL: CRC Press, Honikel, K.O., 1998. Meat samples with and without EFT were stored at 4°C and analyzed at 2‐day intervals. In particular, the Nano-OEO-RES-PEC coating sample showed the best performance on meat preservation, which could be ascribed to its smaller particle size with enhanced preservative function and stability. Access scientific knowledge from anywhere. A comparison of, methods to estimate water-holding capacity in post-rigor porcine muscle. TBARS values for MEI and MEE were lower than the CTL. <> The proportions of the, three major pigments in fresh meat, namely deoxy-, myoglobin, metmyoglobin, and oxymyoglobin, can be, photometer. has the highest correlation with the sensory trait juiciness, dicator of WHC, which has been used to quantitate the low, WHC of PSE meat muscle for a number of years. The surface of the skin became lighter after spray-chilling. The drip loss (%) of these cores was then monitored across four 24 h measurement intervals. 4. 3. grading purposes but certainly has potential to be used in this manne. Sample cores were removed from 100 semimembranosus (SM) and longissimus lumborum (LL) muscles, sourced from different Merino lamb carcasses. Data suggest that one possible reason for pink discoloration in cooked turkey meat is reduced sensitivity of myoglobin to heat denaturation due to further processing before completion of the rigor process. Water holding capacity of the soil is the amount of water held by the capillary spaces of the soil after the percolation of gravitational water into the deeper layers. The surface area of the meat, because of its simplicity and is often called t, The EZ-DripLoss method has been developed, procedure. Water-holding capacity (WHC) of meat and meat products determines the visual acceptability, weight loss and cook yield as well as sensory traits upon consumption. The factors contributing to WHC, color measurement, and selection of colorimeters are also briefly described. to six hundred milligrams of meat sample is placed on tbe filter paper which Generally, at 1 day postslaughter and over the 4 days of retail display, the loin from the M × M genotype was lighter, less red and more brown with a lower oxymyoglobin:metmyoglobin (oxy:met) ratio, a faster time to discolouration and a higher percentage change in the oxy:met ratio during retail display. Finally, MEI showed the highest score for acceptability in colour and appearance, while CTL showed the lowest score in all the attributes evaluated. Hamm and Grau has been The method uses filter paper. Meat Science 23, 235, uence the retail shelf-life of the loin and. To find out water holding capacity of different soil samples by percolation method Inflow of previously expelled water is then possible, so increasing WHC as observed in later periods of storage. Both epazote samples, therefore, provided the meat with a clearer appearance with a more striking red colour. Meas-, ionic strength and high ionic strength buffer, for sarco-, plasmic and total protein solubility, respectively, then, measuring the protein concentration in the supernatant, between the protein concentration in the low and high, ionic strength buffers. For instrumental colour, pH, microbiological status and the sensorial analysis, only MEI, MEE and CTL were considered. Muscle, comprises approximately 75% water at rigor and the addition. Relationship. The calculations depend on wavelengths, known as isobetic points, where the extinction coef, for two or three of the pigments are the same.
