Home canning is a fantastic way to preserve food, ensuring you have a pantry stocked with nutritious meals ready to go. Chicken, a versatile and widely enjoyed protein source, is a popular choice for home canning. However, safety is paramount when preserving food at home, and knowing the correct processing times is crucial to prevent botulism, a serious foodborne illness. This article dives deep into the process of pressure canning chicken in pint jars, providing detailed information on processing times and best practices for a safe and delicious outcome.
Understanding the Importance of Pressure Canning Chicken
Canning chicken requires a pressure canner because chicken is a low-acid food. Low-acid foods lack the natural acidity to prevent the growth of Clostridium botulinum, the bacteria responsible for botulism. The high temperatures achieved inside a pressure canner (240°F or 116°C) are necessary to kill these harmful spores.
Boiling water bath canning, which is suitable for high-acid foods like fruits and pickles, does not reach high enough temperatures to eliminate the risk of botulism in low-acid foods like chicken. Therefore, pressure canning is the ONLY safe method for canning chicken at home. Neglecting this crucial step can have severe health consequences.
Preparing Your Chicken for Canning
The first step to safely canning chicken is proper preparation. This involves selecting fresh, high-quality chicken and following specific guidelines to ensure safe canning.
Choosing the Right Chicken
Start with fresh chicken that has been properly stored. Whether you’re using bone-in, boneless, skinless, or whole chicken pieces, the quality matters. Avoid chicken that has been sitting out at room temperature for more than two hours, as this increases the risk of bacterial growth. Frozen chicken can also be used, but it must be completely thawed in the refrigerator before canning. Never can chicken that has already been cooked.
Preparing the Chicken Pieces
Cut the chicken into manageable pieces that will fit comfortably into your pint jars, leaving the recommended headspace. Remove excess fat and bones. While bone-in chicken can be canned, it requires slightly longer processing times and may result in softer bones. Boneless, skinless chicken is a popular choice because it’s easy to pack and offers a leaner final product.
Options for Packing: Raw Pack vs. Hot Pack
There are two main methods for packing chicken into jars: raw pack and hot pack. Each method has its advantages and considerations.
Raw Pack Method
The raw pack method involves placing raw chicken pieces directly into the jars. This method is faster and requires less pre-cooking. However, it can result in more liquid loss during processing, which may lead to the chicken being less moist.
Hot Pack Method
The hot pack method involves pre-cooking the chicken partially before packing it into the jars. This helps to shrink the chicken, resulting in a fuller jar and less liquid loss during processing. It also helps to drive out some of the air from the chicken, which can improve the vacuum seal. To hot pack, boil, bake, or steam the chicken until it is partially cooked but still firm.
Essential Canning Equipment and Supplies
Before you begin canning, gather all the necessary equipment and supplies. Having everything ready will streamline the process and minimize the risk of errors.
- Pressure Canner: Ensure your pressure canner is in good working condition. Check the seal, vent pipe, and pressure gauge for any damage. If using a dial gauge canner, have it tested annually for accuracy.
- Pint Jars: Use canning jars specifically designed for home canning. Examine jars for any chips or cracks, especially around the rim. Pint jars are a versatile size for canning chicken.
- Lids and Bands: Use new lids each time you can. The sealing compound on used lids may not create a proper seal. Bands can be reused, but ensure they are in good condition and free from rust or dents.
- Jar Lifter: A jar lifter is essential for safely lifting hot jars from the canner.
- Lid Wand: A lid wand helps to easily lift sterilized lids from hot water.
- Bubble Remover/Headspace Tool: This tool is used to remove air bubbles from the jars and measure the correct headspace.
- Large Pot: For pre-cooking chicken if using the hot pack method.
- Cutting Board and Knife: For preparing the chicken.
- Clean Kitchen Towels: For wiping jar rims and cleaning up spills.
Step-by-Step Guide to Pressure Canning Chicken in Pint Jars
Following a detailed, step-by-step guide is crucial for ensuring the safety and quality of your canned chicken.
Sterilizing Your Jars
While not always necessary for foods processed for 10 minutes or more, many canners prefer to sterilize their jars. To sterilize, place clean jars in a large pot of boiling water for 10 minutes. Keep the jars hot until ready to fill. Lids should be simmered in hot water (not boiling) to soften the sealing compound.
Packing the Jars
Based on your preferred method, pack the chicken into the pint jars.
Raw Pack Instructions
- Place raw chicken pieces into the jars, leaving 1-inch headspace.
- Do not add any liquid. The chicken will release its own juices during processing.
- Add 1/2 teaspoon of canning salt per pint jar (optional, for flavor).
Hot Pack Instructions
- Pack the hot, pre-cooked chicken pieces into the jars, leaving 1-inch headspace.
- Cover the chicken with hot cooking liquid (broth or water), maintaining the 1-inch headspace.
- Add 1/2 teaspoon of canning salt per pint jar (optional, for flavor).
Removing Air Bubbles and Adjusting Headspace
After packing the jars, use a bubble remover or non-metallic utensil to gently release any trapped air bubbles. Run the tool along the inside of the jar. Add more liquid if necessary to maintain the 1-inch headspace.
Cleaning the Jar Rims
Wipe the jar rims with a clean, damp cloth to remove any food residue. A clean rim is essential for a proper seal.
Placing Lids and Bands
Place a sterilized lid on each jar, ensuring the sealing compound is facing down. Screw on the band fingertip-tight. Do not overtighten, as this can prevent air from escaping during processing, potentially leading to a broken seal.
Loading the Pressure Canner
Place the filled jars onto the rack inside the pressure canner. Add the amount of water specified in your canner’s instruction manual (usually about 3 quarts). Ensure the water level is below the top of the jars.
Processing the Chicken
Follow these steps carefully to properly process your chicken.
- Secure the canner lid and turn the heat to high.
- Allow the canner to vent steam for 10 minutes to remove air from the canner.
- Close the vent (either with a weight or by closing a valve, depending on your canner model).
- Monitor the pressure gauge and bring the canner to the required pressure.
- Once the correct pressure is reached, begin timing the processing.
Processing Times for Pint Jars of Chicken
This is the most crucial part. Improper processing can lead to unsafe food.
The processing time for pint jars of chicken depends on your altitude. The following processing times are based on recommendations from the National Center for Home Food Preservation.
Processing Times at 10 pounds pressure (dial gauge):
| Altitude | Processing Time (Pint Jars) |
|---|---|
| 0 – 2,000 feet | 75 minutes |
| 2,001 – 4,000 feet | 80 minutes |
| 4,001 – 6,000 feet | 85 minutes |
| 6,001 – 8,000 feet | 90 minutes |
| 8,001 – 10,000 feet | 95 minutes |
Processing Times at 11 pounds pressure (weighted gauge):
| Altitude | Processing Time (Pint Jars) |
|---|---|
| 0 – 1,000 feet | 75 minutes |
| Above 1,000 feet | 75 minutes |
Maintain the correct pressure throughout the entire processing time. Fluctuations in pressure can affect the safety of the canned food. If the pressure drops below the required level at any time, increase the heat and restart the processing time from the beginning.
Cooling and Depressurizing the Canner
Once the processing time is complete, turn off the heat and allow the canner to cool naturally. Do not force cool the canner by running it under cold water, as this can cause the jars to break.
Allow the pressure to return to zero. For dial gauge canners, wait 10 minutes after the gauge reads zero before opening the vent. For weighted gauge canners, remove the weight and wait 10 minutes. Carefully remove the lid, tilting it away from you to avoid steam burns.
Removing the Jars
Use a jar lifter to carefully remove the jars from the canner. Place the jars on a towel-lined surface, leaving space between them to allow for air circulation. Avoid placing hot jars on a cold surface, as this can cause them to crack.
Checking for a Proper Seal
Allow the jars to cool undisturbed for 12-24 hours. After cooling, check the seals. The lid should be concave (curved downwards) and should not flex when pressed in the center. If a lid does not seal, it must be reprocessed with a new lid within 24 hours, or refrigerated and used within a few days.
Labeling and Storing Your Canned Chicken
Label each jar with the date and contents. Store canned chicken in a cool, dark, and dry place. Properly canned chicken can be stored for up to one year.
Troubleshooting Common Canning Issues
Even with careful preparation, canning issues can sometimes arise. Here are a few common problems and how to address them.
- Siphoning: Siphoning occurs when liquid is lost from the jars during processing. This can be caused by overfilling the jars, not removing air bubbles properly, or fluctuations in pressure.
- Broken Jars: Broken jars can be caused by improper handling, sudden temperature changes, or using damaged jars.
- Cloudy Liquid: Cloudy liquid can be caused by starch from the chicken or minerals in the water. It does not necessarily indicate spoilage, but it can be prevented by using filtered water and removing excess fat from the chicken.
- Flat Sours: Flat sours are caused by spoilage bacteria that survive the canning process. This is usually due to under-processing or improper sealing. Discard any jars that show signs of spoilage, such as bulging lids, off odors, or mold.
Safety First: Preventing Botulism
Botulism is a serious and potentially fatal illness caused by the toxin produced by Clostridium botulinum bacteria. These bacteria thrive in low-oxygen environments, such as improperly canned foods.
To prevent botulism, always follow these safety guidelines:
- Use a pressure canner for low-acid foods like chicken.
- Follow recommended processing times and pressures.
- Ensure jars are properly sealed.
- Boil home-canned low-acid foods for 10 minutes before consumption, even if they appear and smell normal. This will destroy any botulism toxin that may be present. If you are at an altitude above 1,000 feet, add one minute of boiling time for each 1,000 feet of elevation.
- Discard any canned foods that show signs of spoilage.
Conclusion
Pressure canning chicken in pint jars is a safe and rewarding way to preserve this versatile protein. By understanding the importance of proper preparation, using the correct equipment, following recommended processing times, and adhering to safety guidelines, you can confidently enjoy delicious, home-canned chicken for months to come. Always prioritize safety to ensure the health and well-being of yourself and your family. Remember to consult reliable resources like the National Center for Home Food Preservation for the most up-to-date information and guidelines.
Why is pressure canning necessary for chicken in pint jars?
Pressure canning is the only safe method for preserving low-acid foods like chicken. This is because botulism spores, which produce a deadly toxin, can survive in improperly canned low-acid foods. The high temperatures achieved during pressure canning (240°F/116°C) are crucial for killing these spores, something boiling water bath canning cannot accomplish.
Since chicken has a pH level above 4.6, it’s considered a low-acid food. The extreme heat generated by a pressure canner eliminates the risk of botulism poisoning by destroying the Clostridium botulinum spores. Therefore, pressure canning is essential to guarantee the safety of home-canned chicken stored at room temperature.
How long do I need to pressure can pint jars of chicken safely?
The recommended processing time for pint jars of chicken in a pressure canner is 75 minutes. This time is for both raw-packed and hot-packed chicken. It is crucial to adhere to these guidelines, regardless of whether you believe the chicken is already cooked.
This specified time ensures the internal temperature of the jars reaches and maintains the necessary level to kill any harmful bacteria, including botulism spores. Deviating from this recommendation can result in unsafe food that could cause severe illness or even death. Always use tested recipes and adhere to established processing times.
What pressure should I use when pressure canning chicken in pint jars?
The correct pressure depends on your altitude and the type of pressure canner you are using (dial gauge or weighted gauge). For dial gauge canners, use 11 PSI for altitudes at or below 2,000 feet. For weighted gauge canners, use 10 PSI. If your altitude is above 2,000 feet, you’ll need to increase the pressure accordingly, consulting a reliable canning guide for specific adjustments.
It is essential to use the appropriate pressure for your situation. Insufficient pressure will not adequately heat the contents of the jars, potentially leading to spoilage and foodborne illness. Always consult a reliable canning resource, such as the USDA Complete Guide to Home Canning, or your local extension office for accurate pressure adjustments based on your altitude.
Is it safe to use a recipe that suggests a shorter processing time for chicken?
No, it is not safe to use a canning recipe that suggests a shorter processing time than the officially recommended time from a trusted source like the USDA. Canning recipes must be scientifically tested to ensure they eliminate the risk of botulism. Deviating from established guidelines is dangerous.
Using an untested or shortened processing time could leave botulism spores alive in the jars, even if the chicken seems perfectly fine upon opening. Botulism toxin is odorless and tasteless, so you cannot detect it. Always follow established, scientifically tested recipes and processing times to ensure the safety of your canned food.
What is the difference between raw-packing and hot-packing chicken for canning?
Raw-packing involves placing raw chicken pieces directly into the jars before adding hot broth or water. This method tends to result in slightly less liquid in the finished product as the chicken releases some of its moisture during processing. Raw-packed chicken may also have a slightly stronger flavor.
Hot-packing involves precooking the chicken pieces before packing them into the jars with hot broth or water. This method reduces the air in the jars, leading to a better vacuum seal and potentially improved color retention. Hot-packed chicken generally shrinks more than raw-packed chicken during processing.
What are the signs of spoilage in home-canned chicken?
Signs of spoilage in home-canned chicken can include a bulging lid, leakage from the jar, a broken seal, or unusual odors upon opening. A cloudy appearance of the liquid or any visible mold growth inside the jar are also indicators of spoilage. Trust your senses and discard any jar that shows these signs.
Even if there are no obvious signs of spoilage, if you are unsure about the canning process or if the seal is weak, it is best to discard the chicken rather than risk consuming potentially contaminated food. Remember, botulism toxin is odorless and tasteless, so you cannot rely on your senses to detect its presence.
What should I do if I suspect my canned chicken might be contaminated?
If you suspect that your canned chicken may be contaminated, do not taste it under any circumstances. The best course of action is to dispose of the jar and its contents safely. The proper way to dispose of potentially botulism-contaminated low-acid foods is to detoxify them.
To detoxify the contents, carefully place the unopened jar in a pan and add enough water to cover it by one inch. Boil for 30 minutes to destroy the botulism toxin before discarding the jar and its contents. This step is crucial to prevent poisoning of yourself, others, or animals that might come into contact with the contaminated food.
