For decades, immersed in studying, working, learning, and teaching in the craft of meat curing, now sharing his passion with you through eat cured meat online resource.

When I started hot-smoking meat, I did wonder if it had any preserving aspect to it.

After exploring all aspects of cold smoking and hot smoking for many years, I’ve been teaching people about cold smoking both on and offline.

It seems a lot of people make the assumption that smoking is preserving. However, there is a difference between preserving and smoking. 

Does Hot Smoking Preserve Meat

No, hot-smoking meat is the process of cooking meat with an element of smoke to enhance flavor. Preserving meat involves slowing anti-microbial activity through drying, salt, acidity, or cold smoke.

It’s a combination of factors that allow meat to be preserved through smoking.

The salt curing & the long cold smoking time are the main factors. Which dries the meat out, the smoke has quite a few ‘preserving’ properties that help with this.

However, there are other techniques for preserving meat, too. My focus is on preserving good flavor, that is what I pursue. Also, some Artisan styling was thrown in for good measure.

Hot Smoking Meat – How Long Will It Last?

Therefore when you hot smoke (hot smoking technique in detail), you are doing the equivalent of cooking meat, so you are looking at lasting about one week. If you vacuum pack obviously you can increase the shelf life. So all the pit master BBQ styles are a form of hot smoking or slow & low.

Hot Smoking Process

  1. Dry salt curing or salt brining the meat
  2. Drying meat to form a pellicle
  3. Hot smoking the meat
  4. Eat the Meat

If you haven’t tried hot smoking, here is a super easy guide below.

Also, here is a hot smoking fish guide, or how to hot smoke on a gas BBQ Guide.

Ways of Preserving Meat

A summary of ways to preserve meat for a short time or longer periods.

  • Oil Bath – Oxygen Removal
  • Fat or Lard Preservation
  • Dry/Wet Curing Meat
  • Dehydrating
  • Cold Smoking

The Oil Bath – Oxygen Removal

When I did some work in Scotland for a year, one of the businesses was a fine-dining celebrity restaurant. The family also owned half a mountain with wild venison (red deer) running around, handy for the kitchen.

One of the chefs was putting away some 40-day aged venison for the 5-course dinner (the menu changed every day). It was an awesome place, though this was quite a few years back now. So I don’t know what it’s like now.

Mr chef was bathing the venison steaks in cold pressed olive oil with rosemary & juniper. He said this meant no air/oxygen could get to it and they could use the venison over the next few weeks. Here is a link to the technique.

COMBAT OXYGEN

Oxygen causes a decline in quality when you store foodstuffs for longer periods in the refrigerator or freezer. A marinade or a thin layer of olive oil protects the meat so that it keeps a little longer. Any layer of fat also protects the meat.

Fat and Lard preservation also utilizes this technique of depriving the meat of oxygen.

Fat or Lard Preservation – Duck Confit or Rillette

Duck hunting season is something I got excited about since I was about 8 years old.  Wild duck and farmed duck work well, this is pure and simply cooked in fat (duck or goose), then packed into sterilized jars.

If not opened they will last months possibly years in the cupboard. Once open, we would generally consume it within a month. Fat, thyme & garlic are the main ingredients.

The classic French dish works very well with bought, farmed, or wild duck.

My friend was pretty proud of this recipe, so he distributed jars and printed recipes as a gift to a select lucky group, including myself.

Dry/Wet Cured Meat

This is both a short-term and a long-term option.

So in terms of the long term, once you have salted the meat appropriately, then you need to dry it out to a minimum of 30% weight loss. This is where the curing chamber or consistent temp and humidity helps.

But for short-term dry curing, I have worked out a successful method, if you want to know more – please find it here.

The main reasons for the curing chamber (how to setup a DIY curing chamber guide I wrote) are:

  • Protection of the meat from bugs
  • You develop a ‘good bacteria’ environment aka penicillin (white fine powder you see on salami and salumi
  • Controlling temperature & humidity 
  • Having some good fresh air flow to help gently dry

Dehydrating

Dehydrating is drying, in a survival context it can be done on a open fire, if enough distance is made from the meat, airflow and thinly cut.

A preferred method is also using the power of salt (curing) and also acidity.

Using acidity, salt, and drying/dehydrating.

Some Jerky or Biltong is hot or cold smoked to give flavor. Either by using a cardboard box method, biltong box, dehydrator, or curing chamber – anyone can make biltong/jerky.

The initial process of drying the meat out already preserves the meat for a few days to a few weeks. It does tend to dry out more and more due to exposure to oxygen.

For the traditional addictive South African biltong it is a bath of salt, vinegar, and (toasted coriander), vinegar is ‘pickling’ technically cooking with acidity, with a flavor and preserving effect.

However, it seems when making biltong it is ‘cooking it’ to a degree…

It coagulates protein. Vinegar breaks the chemical bonds that hold protein strings in a twist, causing the proteins to denature or unravel and “tenderize.” This commonly occurs when meat is marinated in a vinegar-based marinade. With continued exposure to acid, the unraveled protein strings eventually bump into each other and form new bonds. The popular South American raw dish ceviche is based on acid’s ability to denature and coagulate protein without heat: sliced raw fish is “cooked” in acidic ingredients until opaque and firm, but without the flavor changes that would occur if the fish were exposed to high temperatures.

Here’s the link to the above quote from finecooking.com

So preserving for flavor is where I wanted to head. Any thoughts would love to hear from you.

Preserving Meat by Smoking – Cold Smoking

An extension of the dry/wet curing, the cold smoking is more about the smoke to protect the meant and also flavor it.

Under 70°F or 30°C, you are cold smoking meat or food. But it is over a long period of time. First, the meat has to be properly dry or wet cured (here is a article on curing for hot smoking in detail) primarily with salt.

Because cold smoking (article all about cold smoking) is over a long period of time, the smoke basically penetrates through the meat.

The pellicle is a binding of proteins when the meat is dried out after the salting/brining phase. If you want to learn more about pellicles here is a post on it.

One, two, or multi-days – the traditional cold smoking process is an extended period of time maintaining low temperature & humidity which shouldn’t be too high.

During the curing process, the salt performs its job of drawing moisture out; this means the bacteria has breakdowns/spoils has a hard time, and can’t thrive in this low moisture environment. This is truly an ancient craft that can be traced back thousands of years.

Smoking has a long tradition in food cooking and preservation. Cold and hot smoking have different aims and effects on the quality and safety of foods. Cold smoking is mainly used for flavor and to extend shelf-life due to the antioxidant and antimicrobial effects of smoke compounds.

Smokehouse temperatures for cold smoking are typically between 20 to 30 °C (68 – 86 °F). In this temperature range, foods take on a smoked flavor but remain relatively moist. Cold smoking does not cook foods, and as such, meats should be fully cured before cold smoking.

From, https://en.wikipedia.org/wiki/Smoking_(cooking)

This is mostly correction, however.

In a survival content, meat can be sliced thinly and dried on an open fire, therefore drying can be done without salt curing.

The smoking has an anti-fungal & anti-microbial effect on top of the salt’s effect. it also tastes awesome, especially if you are making your own!

What Type of Food Can I Hot Smoke?

Within reason, any type of fresh/dried food can be smoked. Meat such as pork, beef, fish, seafood, and poultry are all popular. Many types of vegetables can be smoked also. Hot Smoking is cooking with the addition of smoke for flavor.

How Long Does it Take to Hot Smoke Meat?

Depending on the density/size of the food, it can be 15 mins at moderate temperatures (270-340°F / 130-180°C) to 8 hours at low temperatures (180-250°F / 80-120°C). However, a short time will mean very subtle smoke flavors. yet, under-smoking is better than over-smoking.
