First, can a pressure cooker be used to sterilize? Unbelievably, pressure cookers are a tool for mushroom cultivators because they can sterilize the substrate layer used for growing mushrooms. It can also sterilize large quantities of substrates.
It would be best if you used a pressure cooker to kill the microorganisms living in the substrate because they can contaminate your mushrooms, rendering them inedible. Even though pressure cookers only reach 7 PSI (Pounds per Square Inch), they generate sufficient heat to eliminate any pathogens that could contaminate your mushrooms.
Generally, a pressure cooker must reach 15 PSI to sterilize the layer for mushroom cultivation. To prevent contamination during growth, this is the purpose of the pressure used to sterilize the substrate.
Before opening the jars after pressure cooking, allow them to cool because this ensures the quality of the sterilization and prevents thermal shock, which can result in broken jars from rapid temperature changes.

Why Should You Use Pressure Cooker For Sterilization?
There are numerous reasons for sterilizing items at home, such as sterilizing your kitchen utensils and other household items. At a time in their lives when they have a million other things to concentrate on, many new parents find an Instant Pot (or other brands of pressure cooker) to be a fantastic tool for preparing nutritious meals quickly.
With a pressure cooker, it is possible to prepare a nutritious meal in a matter of minutes after the birth of a baby, when food preparation typically takes a back seat.
A pressure cooker is ideal for steaming vegetables, making soup, and even cooking rice and other grains, allowing parents to eat quickly and healthily.
Most of a parent’s time is also spent cleaning and ensuring that everything that meets the infant is clean and sterile. There are many specialized sterilizing machines and equipment on the market, but you can save space and money by using a pressure cooker.
It is an excellent idea to sterilize baby equipment in a pressure cooker. It is possible to use a pressure cooker to sterilize baby bottles, pacifiers, and other feeding equipment, which is essential for any parent concerned with maintaining a clean environment for their child.
How Long Does Sterilization Take?
How long do substrates need to be sterile? The duration of sterilization is contingent on the substrate used. 15 PSI is necessary for agar and grain. This level of PSI eliminates contamination and decreases the likelihood that you will waste time. Here is a general list of sterilization times calculated at 15 PSI based on the substrate:
Liquid agar solution | 45 minutes |
Quart-sized grain jars | 1 hour and 30 minutes |
Large 5-pound grain bags | 2 hours |
Large 5-pound sawdust | 2 hours and 30 minutes |
The sterilization time will vary depending on the size of your pressure cooker and how the bags were stacked. The timer is not started until the pressure cooker is full. Before starting the timer, wait for the pressure cooker to reach 15 PSI. Some individuals have discussed using an autoclave, an expensive pressure cooker used to sterilize substrates.
What Else Can a Pressure Cooker Sterilize?
The only type of sterilization that can be performed in pressure cookers is substrate preparation for mushroom cultivation. Pressure cooking for sterilization is quick, simple, and produces minimal clean-up mess.
Glass jars can be sterilized for sauces, jams, chutneys, nut butter, homemade milk, yogurt, and any of your favorite recipes. We know that storing food in clean, sterilized glass jars and bottles is the most hygienic option.
Tips: Always ensure that the item you intend to sterilize in a pressure cooker can withstand the process. Also, ensure that it can be used in a pressure cooker by consulting the manufacturers’ instructions.
How to use pressure cooker for sterilization
In general, the sterilization procedure for pressure cookers is as follows:
- If you are sterilizing a sample in a container (such as agar), ensure it does not exceed two-thirds of the container’s capacity. Place the lids on the jars, but do not entirely secure them; otherwise, the glass jars will explode. Additionally, you can cover jars and glassware with aluminum foil and secure it with masking or autoclave tape.
- Fill the pressure cooker with water to a depth of 1 to 2 centimeters (not enough to start covering the base of the sample). This should be de-ionized water, which can be obtained from our laboratory’s green faucets without hot/cold symbols. Insert a separator into the bottom of the pressure cooker so that the sample does not come into direct contact with the bottom of the cooker. In the video, only a spoon was used.
- Place the sealed pressure cooker on a hot plate over high heat. Ensure that the pressure valve is fully open.
- When steam begins to escape the pressure valve opening, completely close it, and reduce the heat to medium (approx. half the max). Start the timer when a pressure has built up inside the pot and steam is escaping through the pressure valve. The required sterilization time is typically between 20 and 30 minutes.
- When the time is up, please turn off the hot plate and remove the pressure cooker to allow it to cool for approximately 10 to 15 minutes.
- Then, open the pressure valve gradually until steam no longer escapes. This is possible with the Hawkins Big-Boy by slightly lifting the pressure cap with a fork. If the moisture is released too quickly, the sample will boil explosively and spill all over, and in the worst-case scenario, the glass containers will explode.
- Open the pressure cooker and close the samples’ lids. Caution, it will be boiling.

First, the 25-quart All-American cannot be used as a pressure canner, but it can be used for sterilization. Thus, it is a suitable substrate for mushroom cultivation. To create steam, only a tiny amount of water is required. Because it employs a metal-to-metal gasket, there is no need to replace an expensive seal. It can attain a maximum of 17 PSI.
This pressure cooker has been used to sterilize physicians, dentists, first aid stations, and laboratories. All-American designed this specifically as a sterilizer, so it cannot be used for canning. Some may view this as a disadvantage if they are uncertain about their interest in mushroom cultivation. However, once purchased, it will last for many years.
Why would you opt for a sterilizer as opposed to a pressure cooker? First, the All-American 25-quart container is less likely to warp. A sterilizer offers more excellent safety than a pressure cooker. To ensure a quality job, someone who wishes to cultivate mushrooms professionally may choose this. Few customers have reported that this sterilizer prevented all their substrates from becoming contaminated, indicating that it is effective. The replacement components from the manufacturer are inexpensive.

If you are looking for a pressure pot for industrial and commercial use that does not compromise on quality, then the concord steel 100-quart pot is for you. For mass sterilization in industrial settings, you need a pressure cooker, and what better equipment to use than a 100-quart pressure cooker?
This vessel is simple to handle. Its dimensions are 20 inches in height and 21 inches in width, allowing you to store large stencils and implements. When I needed a large pressure cooker for sterilizing large utensils and no such pot was on the market, this pot came to my rescue.
Urgent medical care was required for the rural populace, and sterilizing medical equipment and implements was a pressing need at the time. I discovered this exquisite item and shipped it out immediately after discovering it. The shipment and delivery procedure were very efficient and quick. Upon opening, we discovered a colossal pressure cooker with a large pot and a massive lid to seal it.
The safety mechanisms appeared promising, with lid screws for tightening. The piece is made of stainless steel, so worrying about rust destroying it is unnecessary. Because stainless steel is an exceptional heat conductor, the pot reached the required 15 psi of pressure in record time.
In addition, the dial gauge features three easily adjustable ideal pressure settings. This device, designed for mass disinfection, is more than meets the eye.
It was straightforward to assemble the single components with the included instructions. This pot was clearly distinguished from others by its lid, which could be hung on the side of the pot while the inner pot was being used.
And we are all aware of how annoying it is to find a secure place to rest the lid. This commercial vessel does not include detachable, fully welded pieces for simple cleaning.
Concord has made your life easier by offering one pot equivalent to five pots if you want to perform large-scale sterilization and are searching for multiple pressure cookers.
Key Features
- 100 Quarts
- Brew Kettle is made from Commercial Quality Stainless Steel, Fully Polished.
- All Accessories included in this set are made from high quality 304 Stainless Steel.
- Lid is hangable on the side of kettle.

- Kettle (predrilled) will come unassembled for safe shipping. Assembly takes less than 10 mins, only tool required is a wrench or strong hands)
PROS
- Budget friendly.
- Can work up to the scale of 5 mid sizes pressure cookers.

CONS
- The base of the pot can be off a bit light quality.
Best Pressure Cookers for Sterilization – FAQs
Autoclaving is equivalent to a pressure cooker, especially for small batches. Like an autoclave, the chamber of a pressure cooker reaches temperatures high enough to eliminate bacteria and mold spores.
Start the timer when a pressure cooker has built up inside the pot and steam escapes through the pressure valve. The required sterilization time is typically between 20 and 30 minutes. When the time is up, please turn off the hot plate and remove the pressure cooker to allow it to cool for approximately 10 to 15 minutes.
According to the product literature, electric pressure cookers can reach the necessary temperature and pressure for sterilization. Most can be purchased for less than $150, making them an excellent option for laboratories on a budget.
Experiments at the University of Sao Paulo demonstrated that a pressure cooker is as effective as an autoclave and can reach the required temperatures to kill bacilli. Using a gauze contaminated with bacillus subtilis spores, the effectiveness of deep sterilization was evaluated.
Add one to two inches (2.5 to 5 cm) of water to the pressure cooker. Set your containers inside on something slightly raised off the floor (glass containers may crack if they sit directly on the bottom). Seal the pressure cooker according to the manufacturer’s instructions and heat it on a burner.
After 15 to 30 minutes at 121 °C under a pressure of 106 kPa (1 atm) and a total surface temperature of 121 °C, a typical standard for steam sterilization is reached (Block, 2000).
Place a short rack in the bottom of the pressure cooker, then add 1 cup of water and three pint-sized jars. The jars will not fit inside the pressure cooker with the lid on if the rack is too tall, but you should never place the jars directly on the pot.
You will be fine. However, I recommend adding two or three waters if they are pint jars.
The answer is… possibly. If the pressure is decreased, total sterilization can be achieved only by increasing the sterilization time. If you are in the market for a pressure cooker, you should consider purchasing one with a 15 PSI pressure rating.
As the temperature and pressure increase, the amount of time needed to sterilize objects can drastically decrease. Steam sterilization is more effective than dry heat sterilization because the moisture in steam is a superior heat conductor and penetrates the load more effectively.
Conclusion
Typically, it would be best to use a coil top or a natural gas range to cook with a pressure cooker. The pressure cooker’s weight can cause damage to glass stoves or even shatter the glass. Adhere to the safety instructions in the letter.
Pressure cookers can potentially be dangerous, but if you adhere to the instructions, they pose no greater risk than other kitchen appliances. High temperatures kill contaminants such as mold, fungus, and bacteria in pressure cookers. Always clean your pressure cooker after use so it can be used again.
