Bone broth, with its rich collagen content and minerals, has gained popularity for its health benefits and culinary versatility. However, because it is a low-acid food, it requires careful handling and adequate processing time under pressure to eliminate harmful bacteria. The process of pressure canning transforms fresh broth into a shelf-stable product, making it convenient to store and use whenever needed without compromising on taste or nutrition.

In the following sections, we’ll explore the key factors that influence pressure canning times for bone broth, including jar sizes, altitude adjustments, and safety guidelines. Whether you’re preparing broth from beef, chicken, or other bones, understanding these fundamentals will empower you to preserve your broth confidently and effectively.

Recommended Pressure Canning Times and Techniques for Bone Broth

When pressure canning bone broth, the primary goal is to ensure that all harmful bacteria and spores, especially Clostridium botulinum, are completely destroyed. Bone broth, being low in acid, requires precise heat and time to achieve safe preservation. The recommended processing times vary depending on the jar size and the pressure used.

For safe canning, maintain a pressure of 10 to 15 psi, adjusted for your altitude. Typically, a pressure of 10 psi is used for altitudes below 1,000 feet, increasing by 1 psi for every additional 2,000 feet above sea level.

Processing times for bone broth are generally longer than for other canned foods because of its dense protein and mineral content. The following table outlines standard pressure canning times for bone broth in pint and quart jars:

Jar Size Pressure (psi) Processing Time (minutes)
Pints (16 oz) 10 psi 75
Quarts (32 oz) 10 psi 90
Pints (16 oz) 15 psi 60
Quarts (32 oz) 15 psi 75

It is essential to preheat the bone broth before filling jars, ideally keeping it hot (around 180°F or 82°C), to reduce the canning time and prevent jar breakage due to thermal shock. Leave a headspace of about 1 inch in each jar to allow for expansion during processing.

Additional best practices include:

  • Using new lids and sterilized jars to ensure a proper seal.
  • Venting the pressure canner for 10 minutes prior to timing to expel air and allow steam to fill the chamber evenly.
  • Allowing the pressure to return to zero naturally after processing; do not force-cool the canner, as this can cause jar breakage or seal failure.

Factors Affecting Pressure Canning Duration for Bone Broth

Several variables influence how long bone broth should be pressure canned, requiring adjustments to the base processing times:

  • Altitude: As altitude increases, atmospheric pressure decreases, requiring higher pressure or longer processing times to reach the necessary temperature for sterilization.
  • Jar Size: Larger jars require longer processing times because heat penetration takes more time.
  • Bone Broth Density: Broth made with a high concentration of bones, marrow, or gelatin may require slightly longer processing times due to increased viscosity.
  • Equipment Variability: Different pressure canners may have varying heat distribution and pressure accuracy, so it is important to rely on a calibrated gauge and manufacturer instructions.
  • Acidity Level: Though bone broth is low-acid, adding vinegar or lemon juice can alter the pH, but this is generally not recommended for bone broth preservation.

Step-by-Step Pressure Canning Process for Bone Broth

To ensure safe and effective pressure canning of bone broth, follow this detailed procedure:

  • Prepare Bone Broth: Strain broth to remove solids, keep it hot, and skim off excess fat if desired.
  • Sterilize Jars and Lids: Clean jars thoroughly and sterilize by boiling or using a dishwasher with a sanitize cycle.
  • Fill Jars: Pour hot bone broth into jars, leaving 1-inch headspace.
  • Remove Air Bubbles: Use a non-metallic spatula to gently remove trapped air bubbles.
  • Wipe Jar Rims: Clean rims with a damp cloth to ensure a good seal.
  • Apply Lids and Rings: Place lids on jars and screw rings fingertip-tight.
  • Load Canner: Place jars on the rack inside the pressure canner, ensuring they do not touch.
  • Add Water: Add recommended water volume to the canner (usually 2-3 inches).
  • Seal and Vent: Close the lid, heat the canner, and vent steam for 10 minutes.
  • Apply Pressure: Adjust heat to reach the target psi according to altitude.
  • Process: Maintain pressure for the specified processing time based on jar size and pressure.
  • Depressurize: Turn off heat and allow the canner to depressurize naturally.
  • Remove Jars: Carefully open the lid, remove jars with a jar lifter, and place on a towel or rack.
  • Cool and Store: Let jars cool undisturbed for 12-24 hours, then check seals and store in a cool, dark place.

Signs of Properly Canned Bone Broth and Troubleshooting

After processing, it is critical to verify the integrity of the sealed jars to avoid spoilage or foodborne illness. Properly canned bone broth jars should exhibit:

  • A concave lid with no movement when pressed.
  • Clear broth with no unusual cloudiness or separation beyond normal gelatin settling.
  • No unpleasant odor upon opening.
  • No bulging lids or leaking liquid.

If a jar fails to seal, refrigerate and consume the broth within a few days or reprocess it within 24 hours using the same pressure canning guidelines.

Common issues and solutions include:

  • Jar Breakage: Avoid sudden temperature changes and use correct headspace.
  • Seal Failure: Ensure rims are clean, lids are new, and rings are fingertip-tight only.
  • Under-processing: Always follow recommended times and pressures; do not reduce them to save time.

Following these guidelines will maximize safety and preserve the rich nutritional qualities of your homemade bone broth through pressure canning.

Recommended Pressure Canning Times for Bone Broth

When pressure canning bone broth, the goal is to safely preserve the broth by eliminating harmful bacteria, including Clostridium botulinum spores, which cannot be destroyed by boiling water alone. The time required depends on the jar size, altitude, and pressure used. Below is a detailed guide to pressure canning bone broth safely.

Bone broth is a low-acid food and must be processed in a pressure canner to reach the temperatures necessary for safe preservation. The USDA recommends processing times that ensure the destruction of microorganisms and enzymes that cause spoilage.

Jar Size Pressure (PSI) Altitude 0-1000 ft Altitude 1001-3000 ft Altitude 3001-6000 ft
Quart (32 oz) 10 PSI (Dial Gauge) 20 minutes 25 minutes 30 minutes
Quart (32 oz) 15 PSI (Weighted Gauge) 20 minutes 20 minutes 25 minutes
Pint (16 oz) 10 PSI (Dial Gauge) 20 minutes 25 minutes 30 minutes
Pint (16 oz) 15 PSI (Weighted Gauge) 20 minutes 20 minutes 25 minutes

Notes:

  • The processing time is the same for pints and quarts when pressure canning bone broth.
  • If your pressure canner uses a dial gauge, use 10 PSI; if it uses a weighted gauge, use 15 PSI.
  • Adjust pressure according to your altitude to compensate for lower boiling temperatures.
