Pros of Freeze-Dried Foods
Long shelf life:
Freeze-dried foods have an extended shelf life, usually between 25-30 years, making them ideal for long-term food storage and emergency preparedness. Some foods have shorter shelf-life depending on oil, fat, and sugar content.
Lightweight:
Freeze-dried foods are lightweight, making them easy to transport and store, making them ideal for outdoor enthusiasts like hikers and campers.
Nutrient retention:
Freeze-drying preserves the nutrients and flavor of fresh fruits, vegetables, and meats, making them a healthy and delicious option for meals.
Easy to prepare:
Freeze-dried foods are easy to prepare, just add water, and most are ready to eat without the need to cook.
Convenient:
Natural State Freeze Dried's foods come in resealable packaging, making them easy to pack and transport, and they also take up minimal space in your pantry or backpack.
Cons of Freeze-Dried Foods
Cost:
Freeze-drying is a complex process that requires expensive equipment and relatively high levels of electricity consumption, making freeze-dried foods more expensive than other preservation methods.
Texture:
Freeze-dried foods may have a slightly different texture than fresh or canned foods, and some people may prefer other methods.
Re-hydration time:
Some freeze-dried foods may require longer rehydration times, and may not be as quick and convenient as using canned foods in the home.
Pros of Dehydrated Foods
Cost-effective:
Dehydrating is a simple process that can be done at home with a dehydrator, making it a more cost-effective option compared to freeze-drying.
Versatile:
Dehydrating can be used for a wide range of fruits, vegetables, and meats, allowing for a variety of tasty options.
Convenient:

Shelf life:
Dehydrated foods have a shelf life of several months, making them ideal for short-term food storage.
Customizable:
Dehydrating allows you to add your own flavors and seasonings to foods, making it easy to personalize your meals to your taste preferences. Dehydrating also causes food to lose volume and shrink which is helpful if maximizing space is your greatest priority.
Cons of Dehydrated Foods
Nutrient retention:
Dehydrating can result in the loss of some nutrients in foods, compared to freeze-drying.
Texture:
Dehydrating can change the texture of foods, and some people may find them unappealing.
Preparation time:
Dehydrating takes time, as foods need to be dried for several hours to several days, making it less convenient than other preservation methods.
Flavor:
Dehydrating can result in a loss of flavor in foods, compared to freeze-drying or fresh foods.
Storage:
Dehydrated foods are sensitive to moisture and must be stored in airtight containers, making it more difficult to store and transport.
Pros of Pressure Canning
Safety:
Pressure canning is a safe and effective method of preserving low-acid foods, such as meats, vegetables, and soups, by destroying harmful bacteria that can cause foodborne illness.
Shelf life:
Pressure canned foods have a long shelf life, making it ideal for long-term food storage.
Convenient:
Pressure canning allows for easy storage and transport of foods, making it ideal for families who like to stock up on pantry essentials.
Cost-effective:

Cons of Pressure Canning:
Time-consuming:
Pressure canning can be time-consuming, as the canning process requires careful preparation, monitoring, sterilization, and processing times to ensure food safety.
Equipment:
Pressure canning requires specialized equipment, such as a pressure canner, which can be expensive. Depending on time of year and supply chains, canning lids and specific jars can be difficult to find.
Nutrient retention:
Pressure canning can result in the loss of some nutrients in foods due to high heat, compared to freeze-drying.
Texture:
Pressure canning can change the texture of some foods, and some people may find the texture unappealing.
Safety:
