Exploring the Longissimus Muscle: Unraveling its Correlation with Meat Quality in Bos indicus and Crossbred Bulls
Published on: July 12, 2024
Summary
Meat
Area of Science:
- Food Science
- Meat Science
- Biophysics
Background:
- Water-holding capacity is crucial for meat quality.
- Understanding water behavior during heating is essential for processing.
- Nuclear magnetic resonance (NMR) offers insights into water dynamics.
Purpose of the Study:
- To investigate the water condition in cured and uncured pork during heating.
- To determine the influence of ageing time and curing on water immobilization.
- To characterize water components using NMR relaxation methods.
Main Methods:
- Heating pork samples to 80°C.
- Analyzing transverse magnetization decay functions using NMR.
- Identifying and quantifying water components based on relaxation times.
Main Results:
- Five water components were distinguished, with a major component (60-70%) representing immobilized water (35-45 ms relaxation time).
- Heating-induced changes in immobilized water content were significantly affected by ageing time and curing.
- Uncured pork showed maximum immobilized water and strongest bonding at 6-7h and after 48h post-mortem.
- Cured pork exhibited highest immobilized water after 48-96h post-mortem, with stronger bonding when cured early or after 96h.
Conclusions:
- Ageing time and curing significantly alter water immobilization and bonding in pork during heating.
- NMR relaxation analysis effectively differentiates water states in meat.
- Optimized curing and ageing strategies can enhance water retention and quality in processed pork.

01:19Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
01:14Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
01:16Tonicity in Animals
Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells. In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside the cell,...
00:59Tonicity in Animals
The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...
01:19Body Water Content and Fluid Compartments
Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions (Na+) and chloride...
