Learning objectives l.jpg

Learning Objectives

  • List 3 types of sausage.

  • Name 4 main ingredients and their purpose.

  • Explain the function of cure and acceptable cure rates.

  • Identify the critical control points of a HACCP plan in sausage making.

  • Recite the cooling requirements for sausage.

  • List 4 items that are required on a sausage label.

Sausage history l.jpg

Sausage History

  • Sausage production is one of the earliest forms of food preservation

  • The word sausage is derived from the Latin word “Salsus” which means salted meat

Role of salt l.jpg

Role of Salt

  • Salt plays a more limited role in sausage preservation today

  • Present day salt levels provide less of a preservative effect than the higher levels of the past

  • Most sausage recipes contain 1-3% salt

  • Salt levels are usually adjusted for taste

Sausage definition l.jpg

Sausage Definition:

A mixture of ground or chopped meats combined with spices and other ingredients and usually formed or shaped in casings of various sizes

Primary sausage types l.jpg

Primary Sausage Types

  • Fresh Sausages

  • Cooked Sausages

  • Fermented Sausages

  • Meat Loaves and Jellied Products

Fresh sausages l.jpg

Fresh Sausages

  • Raw/uncooked meat product

  • Does not contain the “curing” ingredient nitrite or nitrate

  • Examples are: fresh pork sausage, fresh bratwurst, and fresh Italian sausage

Cooked sausage l.jpg

Cooked Sausage

  • Fully cooked ready-to-eat sausages

  • Most are also smoked but may be water or steam cooked as well

  • May be eaten without reheating

  • Examples include: wieners, smoked sausages, bologna, cooked bratwurst

Fermented sausages l.jpg

Fermented Sausages

  • Have a characteristic “tangy” flavor

  • Produced through fermentation by lactic acid producing bacteria or the direct addition of encapsulated acids

  • These sausages can be shelf-stable with the proper amount of drying and acidification

  • Semi-dry: summer sausage and snack sticks

  • Dry: pepperoni, hard salami

Meat loaves and jellied products l.jpg

Meat loaves and Jellied Products

  • Loaves: Mixtures of chopped meat that are usually “formed” and cooked in pans or metal molds

    • Examples: pickle and pimento loaf and honey loaf

  • Jellied products: consist of a cooked mixture of meat chunks placed in gelatin

    • Examples: jellied roast beef and head cheese

Head Cheese

Sausage ingredients l.jpg

Sausage Ingredients:

  • Meat

  • Salt

  • Spices

  • Cure

  • Reducing Agents

  • Binders and Extenders

  • Water

  • Casings

Slide15 l.jpg


Use only fresh

meat in good

condition and

from an



  • Maintain all meats at a temperature of 41°F or less during storage and production prior to cooking.

Slide16 l.jpg


  • Salt is a necessary ingredient for flavor

  • It aids in preserving some sausages

  • It is essential for extracting the “soluble” meat protein that is responsible for binding the sausage together when the sausage is heated

  • Most sausages contain 1-3 % salt

Spices l.jpg


  • All spices and seasoning should be fresh to achieve maximum and consistent flavors

  • Store seasonings at 55°F or below in air tight containers to maintain freshness

Meat curing ingredients l.jpg

Meat Curing Ingredients

  • Nitrates and nitrites are the common “curing” ingredients used in the production of sausage

  • Nitrite is the compound that distinguishes fresh products from cured products

  • Nitrate is converted to nitrite during the fermentation and cooking process

Function of cure l.jpg

Functionof Cure

  • provides protection against the growth of botulism

  • extends shelf life

  • stabilizes the flavor of the cured meat

  • used to achieve the characteristic flavor and color

Cure caution l.jpg

Cure: Caution !!

  • Too much: can be toxic to humans!

  • Too little: can result in the growth of harmful bacteria!

  • Federal regulations:

    • maximum of 2.75 ounces of sodium or potassium nitrateper 100 pounds of chopped meat, or

    • 0.25 ounces of sodium or potassium nitriteper 100 pounds of chopped meat

Cure rates are critical l.jpg

Cure Rates are Critical!

  • Most cures are added in the form of commercial premixes

  • Use the cure premixes according to labeled directions only

  • Any use other than according to labeled directions will produce an unsafe and illegal product

Addition of cure ingredients l.jpg

Addition of Cure Ingredients

  • Today we use injection, tumbling and direct mixing of cure ingredients

  • Tumbling forces the cure into the muscle under vacuum

  • Other methods include:

    • Dry rubbing

    • Artery pumping

    • Soaking in brine containing cure

Curing accelerators l.jpg

Curing Accelerators

  • Speed up the curing process, reduce the holding time

  • Examples are ascorbic acid (vitamin C) or sodium erythorbate (isoascorbic acid)

  • Must be used according to labeled directions

Binders and extenders l.jpg

Binders and Extenders

Binders -

  • Help to improve flavor and retain natural juices.

    Extenders -

  • Can reduce the cost of sausage formulation.

  • Examples: nonfat dry milk, cereal flours, and soy protein products

Water l.jpg


  • Added torehydratethe nonfat dry milk and toreplace the expected moisture lossduring smoking and cooking

  • Up to10 percent by weight of watermay be added to most sausages

  • No water is added to sausages that will be dried

Casings l.jpg


  • Casings are either natural or synthetic

  • Natural casings are from sheep, hog, or cattle intestines or manufactured from collagen (an animal protein)

  • Synthetic casings are usually made from cellulose

Casing label requirements l.jpg

Casing Label Requirements

  • Beginning Sept. 5, 2001 FSIS regulations require sausage manufacturers to label the source of natural sausage casings if they are derived from a different type of meat or poultry than the meat or poultry encased in the sausage.

  • Sausage products encased in regenerated collagen casings will have to have a statement on the label disclosing the use of regenerated collagen. (The processing of regenerated collagen casings renders the detection of the species proteins impossible).

Product identity and standards l.jpg

Product Identity and Standards

  • Processor must be familiar with the Standard of Identity for the products produced.

  • Federal regulations are very specific in limiting the fat content, the amount of water added, the presence of extenders and variety meats in sausages.

Haccp plan l.jpg


  • A proper HACCP plan should be followed for the safe production of meat products.

  • A HACCP plan provides a careful analysis of the hazards and describes critical control points in the process to control these hazards.

Steps in processing l.jpg

Steps in Processing

  • Particle Size Reduction:

    • Grind; Chop; Mince; Shred; Chunk

  • Mixing:

    • Mixers; Massager; Tumblers: Chopper: Emulsifier

  • Stuffing

  • Linking/Tying

  • Fermenting (optional)

  • Smoking/Cooking

  • Chilling

  • Peeling/Packaging

Cooking ccp l.jpg

Cooking (CCP)

  • All meat products must be cooked to the required temperature to kill pathogens

  • 158°F is considered adequate for pork and beef

  • 160°F is considered adequate for poultry

  • Internal cook temperature and cook times must be carefully monitored and recorded

Cooling l.jpg


  • FSIS Compliance Guidelines recommend that cooked meat products be cooled to below 80°F in less than 1.5 hours and below 40°F in less than 5 hours

Packaging l.jpg


  • Care must be taken to prevent cross contamination of cooked meats prior to packaging

  • Specific procedures must be followed if cooked meat products are vacuum packaged

Packaging34 l.jpg


  • When packaging ready-to-eat foods, limit bare hand contact

  • Utensils, tissues or gloves must be used

Labeling l.jpg


All prepackaged meat products must be properly labeled to include the following:

  • Product name

  • Ingredient statement containing a complete list of ingredients.

  • Handling/perishability statement-“Keep Refrigerated” or “Keep Frozen” must be provided on all products that are not shelf stable. Safe handling instructions must be provided on prepackaged raw meats.

  • Statement of net weight

  • Name and addressof the manufacturer/ distributor

Storage and display l.jpg

Storage and Display

  • All meat products must be held at a temperature of 41°F or below while in storage or display

  • Raw meats must be stored below and away from cooked meats

Jerky l.jpg


  • Meat cut into thin strips and then dried to preserve it

  • It can be flavored or treated during the drying process to improve flavor or nutritional content

Jerky38 l.jpg


  • Made from beef, venison, moose, elk, antelope and other game animals

  • Trim all of the fat and membrane that you can as you cut up the meat

  • Cut the meat into thin strips across the grain of the meat

  • The thinner the strips are, the quicker it will dry

Drying jerky l.jpg

Drying Jerky

  • Lay out strips on a sheet in a single layer

  • Lay the meat slices on a grill or grate that allows air to reach all parts of the slice

  • Store in a cool dry area in a sealed container after it is well cooled

Jerky40 l.jpg


  • Jerky meat withcure can be cold smoked or dried at lower temperatures

  • Jerky meat without cure must be cooked or processed at temperatures greater than 160ºF
