Why do we Smoke Meats?

Smoked Meat Technologies An ancient food preservation technique
History• Prehistoric: flavor & for drying
and warding off flies (fish & game).
• Ancient: preservation & flavor.
• Romans/Etruscans: Parma ham (100 B.C. - Cato’s writing),
fish, cheese
• Greeks: fish
• Gauls: pork
• Americas: fish, game
• Colonial America: preservation & flavor. Examples:
• Pork: Example - Virginia Country
Ham
• Venison
• Fish

Colonial America & 17-18th Century Europe -“Smoak-houses”, “Meat houses”, & In-home “smoaking”
Meats hung for 2+ weeks above the fire. Product was then moved to another location in the smokehouse for up to 2 years.

Smoked Meat Technologies An ancient food preservation technique
1. Traditional Wood Smoke (Naturally smoked) - smoke generated from the burning of hardwoods, hardwood dust, corn cobs, mesquite, etc. Vaporous and condensed smoke phases are transferred to the smokehouse and meat products.
2. Natural Smoke Condensates (NSCs)- smoke that has been cooled and condensed to form a liquid – a process identical to that of traditional smoke being applied to a meat product.
Wood Smoke Types - Definition
6
● Primary Smoke Descriptors:• Smoky - The penetrating, dark brown, acrid aromatic of charred wood.• Ashy - Black, charred aromatic associated with residue of unwashed ashtrays.• Scorched - Aromatic associated with charring or burning.
• Creosote - Tarry, phenolic aroma associated with smoke and solvents.• Green Wood - Aromatic associated with green wood/small young branch
wood.
● Secondary Smoke Descriptors:• Salty• Sweet• Sour• Bitter• Astringent

Traditional Wood Smoke –Fuel Sources & Quality Factors
1. Smoke Fuel Sources:a. Hardwoods - hickory, mesquite, alder, maple, oak, cherry, poplar, apple, beech, etc.b. Softwoods - from conifers. Ex.pine, cedar, spruce, etc.c. Corncobs
2. Smoke Fuel Forms:a. Logs - used in Pit-style house or Smokerb. Sawdust & Wood Chips - used in generator
3. Factors affecting Smoke Qualitya. Wood or Fuel Source b. Generation Temperature - Recommended range: 600°F - 650°F
1. Acids: 400-500°F2. Phenols & Carbonyls: 600°F3 Polycyclic Hydrocarbons: 750°F
c. Air flowd. Moisture: #Moisture, $ Phenols, Acids, & Carbonyls.

Smoke and SpiceWood Type Characteristics Good Food Matches
Hickory Pungent, smoky, bacon-like flavor. Beef, Pork, chicken, game, ham, cheese. Pecan Rich and more subtle than hickory, but similar.
Burns cool, so ideal for very low heat smoking. Beef, pork, chicken, lamb, fish, cheeses.
Mesquite Bitter, more bold flavor than hickory. Tends to burn hot, so use carefully.
Grilled meats, especially beef. Most vegetables.
Alder Delicate flavor that enhances lighter meats. Salmon, swordfish, other fish. Also good with chicken and pork.
Oak Forthright but pleasant flavor. Blends well with a variety of textures and flavors.
Beef (particularly brisket), poultry, pork.
Maple Mildly smoky, somewhat sweet flavor. Try mixing maple with corncobs for ham or bacon.
Poultry, vegetables, ham.
Cherry Slightly sweet, fruity smoke flavor. Poultry, game birds, pork. Apple Slightly sweet but denser, fruity smoke flavor. Beef, poultry, game birds, pork
(particularly ham). Peach or Pear Slightly sweet, woodsy flavor. Poultry, game birds, pork. Grape vines Aromatic, similar to fruit woods. Beef, turkey, chicken. Wine barrel chips Wine and oak flavors. A flavorful novelty that
smells wonderful, too. Beef, turkey, chicken, cheeses.

Wood Smoke Composition -Definition
1. What is Smoke? a gas or vapor derived from the combustion of wood.
2. Why is it visible? steam and organic compounds condense in the atmosphere
3. Source of Smoke Compounds in Wood:a) Cellulose (40-45% of wood): carbonylsb) Hemicellulose (20-35% of wood): acids,
carbonylsc) Lignin (18-30% of wood): phenols
9
The gas gives it a ring.● Smoke Ring is created when NO2 is
absorbed into the meat surface and reacts to form nitrous acid.
The flavor is in the JUICE!!● Smoke flavor is from the liquid phase of
smoke● Phenols deliver unique smoke flavor● Humidity and surface moisture are key● High humidity is critical● A moist surface delivers more flavor
Traditional Wood Smoke
• Gaseous Phase• NO
• Liquid Phase• Tars – largest component
• Acids• Phenols• Carbonyls
• Solids• Ash• Organic Matter
Natural Wood Smoke Components
Smoke Ring
10
The Smoke Ring● Smoke ring comes from Nitrogen (N) in
the wood and the Oxygen (O) and Hydrogen (H) in the atmosphere and meat
● When the 2 meet they form HNO2 (nitrous acid) which penetrate the meat to form a pink “smoke ring”
● Basically…wood + air + meat = smoke ring
Increasing Smoke Flavor
● Humidity and surface moisture are critical
● Surface moisture captures the liquid phase of smoke and continuously bastes the product with the flavor components of smoke.• High relative humidity• Fuller smokers/pits (or pans of
water to replace missing product)• Slow/low air movement (fogs of
smoke)• Apply smoke in the early stages of
cooking before surface moisture is gone
11
Increasing Smoke Flavor● Modest dry bulb
temperatures (low and slow)• Searing or sealing the
surface of the product locks juices in BUT slows or even stops smoke penetration
• Surface proteins denature or seal at 145 – 150 F
• Really should be managed with thinner meats (e.g. ribs)
Increasing Smoke Flavor● Wood
• Wood burning at 500 – 600 F generates the greatest amount of smoke
• Hot burning wood burns in excess of 1,000 F
• Larger wood logs and large wood chunks burn more slowly and cooler generating greater volumes of smoke
• Round logs burn more slowly and generate more smoke than split logs
• Smoke represents unburned fuel/wood hence the term smoldering
• Greener or wetter woods generate more dense smoke
