Meat Value Addition and Processing

Flashcards covering core terminology and concepts on meat processing, value addition, minimal versus further processing, shelf-life preservation, and quality degradation factors.

Meat Processing

Any mechanical, chemical, or enzymatic treatment of meat that alters the form in which it originally occurs.

Value-Added Product

A product whose raw material has undergone processing and significant transformation to achieve an increased market value and improved eating characteristics.

Cooking (Processing Function)

The most commonly used meat processing method applied to improve product safety.

Ready-To-Cook (RTC)

A processing convenience category describing meat products that have been formulated, prepared, and packaged so they require only cooking by the consumer prior to consumption.

Ready-To-Eat (RTE)

A convenience category describing meat products that are fully prepared and require no further cooking prior to consumption.

Individually-Quick-Frozen (IQF)

A rapid freezing and portion-control method that freezes separate meat pieces individually to enhance product functionality and convenience.

Minimal Processing

Processing that involves no change in chemical composition, encompassing raw intact cuts, raw non-intact cuts with no added ingredients, edible offal/variety meats, and raw lean recovered meat.

Further Processing

Processing that causes changes in chemical composition to enhance quality and add value to low-quality, low-value meat raw materials.

Shelf Life

The length of time before meat products become unpalatable, unsafe for human consumption, or unattractive in the display case.

Fresh Meat pH

The close-to-neutral pH range of $5.3$ to $6.5$ found in fresh meat, which contributes to its high perishability alongside high water activity and nutrient availability.

Mechanical Refrigeration

The primary form of shelf-life extension and preservation in meat merchandising, without which meat shelf life lasts only a few hours.

Meat Spoilage

End-of-shelf-life deterioration marked by a slimy appearance (caused by organic acids, protein degradation, and mold/yeast growth), discoloration from pH changes, uncharacteristic texture, and offensive volatiles produced by spoilage bacteria.

Meat Oxidation

End-of-shelf-life deterioration caused by lipid and protein oxidation, resulting in discoloration and offensive off-flavor volatiles, typically without producing a slimy appearance or significant texture change.

Fresh Processed Meat Products

A class of processed meat products that includes fried sausages, hamburgers, kebabs, and nuggets.

Cured Whole Muscle Meat Products

A category of processed products derived from whole muscle cuts, including raw cured beef, raw or cooked ham, bacon, corned beef, and cured sausages.

Restructured Meat

Products formed by assembling smaller pieces or cuts of meat into a cohesive product, including items such as smoked sliced beef and boneless hams.
