Study Notes
Meat Animals and Meat Quality
- Meat is any part of an animal intended or judged safe for human consumption (CAC/RCP 58-2005)
Common Meat Animals
- Domestic ungulates (cattle, pigs, sheep, goats, horses)
- Domestic birds (poultry)
- Lagomorphs (rabbits, hares, pikas)
- Farmed game
- Farmed game birds
- Wild games (mammals and birds)
- Other animals, as specified
Meat Types
- Red meat (sometimes called dark meat)
- White meat
Colour Differences
- Colour differences are due to variations in muscle activity, influencing muscle pigment (myoglobin)
Meat Quality Attributes
- Quality is defined by two aspects:
- Safety
- Eating quality
Safety
- Meat should be free of harmful microorganisms or unfavorable substances
- Signs of a healthy animal include quick appearance, good reflexes, movement, and normal health parameters
- Pregnant animals' blood may be contaminated with fetal waste materials
Eating Quality
- Defined by the consumer, considers
- Freshness
- Proportion of lean to fat
- Palatability (texture & consistency, juiciness, flavor)
- Appropriate use of additives/extenders
Meat Quality Preferences
- Tropical countries often prefer mature animals, while temperate countries often prefer young animals
- Preferences differ due to cultural practices and food preparation tastes
Meat Inspection and Quality Control
- General meat inspection is an initial step to screen unacceptable meat through visual and physical examination
- Meat quality control uses approved techniques to determine quality
- Quality control is essential for all meat processing plants
Meat Quality Control Methods
- There are different methods, from simple to sophisticated, depending on the needed accuracy
- The methods are used to inform consumers and processors about meat quality.
Sensory (Organoleptic) Evaluation
- Involves describing meat and meat product attributes through the senses.
- Senses of sight, smell, taste, and touch are used to evaluate color, size, shape, cleanliness, odor, flavor, and texture.
- Can be done by one person, or a more objective group of panelists
Sensory Evaluation methods
- Paired Comparison Test
- Triangle Test
- Hedonic/Acceptability Test
Color
- Fresh meat turns bright red when exposed to air (oxygen+myoglobin)
- Meat loses freshness and its bright color when without exposure to air.
- Consumers prefer tender and juicy meat.
- The best way to examine consistency is by chewing
Smell and Taste
- Smell and taste are related, and evaluated simultaneously
- Fresh meat has a slightly acidic smell that intensifies with time (lactic acid formation)
- Spoiled meat has an unpleasant odor
- Freshness is marked by smell and appearance
Physical Tests
- Physical methods focus on meat condition or surrounding conditions (storage rooms, etc.
- Includes temperature, humidity and water activity.
- Temperature: Low temperatures are essential for preventing microbial growth, during chilling, and freezing
- Humidity: High humidity can cause evaporation and wetting
- Water activity (aw) measures the available water in meat; microbial growth is affected by water activity.
- Airtight Closure: Important fro shelf stable meat products. Techniques to check for leaks.
Chemical Tests
- Chemical tests determine specific substances within meat and meat products.
- Includes pH measurement—important for microbiological aspects.
- pH: Ranges in live animals and carcasses. Different meats have different pH values
- Moisture/fat/protein determination: Methods to determine these components in meat
Microbiological Examination
- Aims to determine bacterial contamination in meat and meat products
- It needs laboratory facilities
- Includes contact (trigger) methods and quantitative methods, such as total plate count and selective plate count
- Sampling methods (contact & destructive) are needed
