It is perhaps one of the longest-standing problems that humans have faced in getting our food throughout the ages that the things we want to eat will spoil long before they can be moved from wherever they naturally occur to wherever it is that we want to eat them. It is a conundrum dating back to biblical times at the very least – people can only move so quickly from here to there, and food will go bad before the journey is over no matter how fresh it was when one set out.
Humanity, though, loves nothing more than a challenge, and people have come up with an inspiring number of ways to make sure that no matter what it is they want to serve, it is available to them the world over. The simplest way that this would have been done was, in ancient times, the practice of sending live animals somewhere instead of dressed meat; even in the Bronze Age, it was well known that a cow would survive a trip during which beef would reliably rot.
The idea of smoking meat to preserve it has been found to have originated separately in numerous cultures across the globe, with each one using slightly different methods and recipes to achieve comparable results. Smoked meat is cooked over relatively low heat for a long time, causing it to dry out and take on the added flavor of the smoke in the process; this meat was both tougher and lighter than ordinary cuts, and would rapidly become a favorite for wayfarers of all sorts.
In places where the climate permitted, people turned to the sun as their primary source of heat for preserving food; sun-drying fruit, vegetables, and different cuts of meat became exceptionally popular in colonial England and allowed the produce from different parts of the empire to be shared with one another. Dried food would not only keep for a voyage halfway around the globe but could be stored and moved as indelicately as one please and still be soaked back to a palatable form.
Several cultures have developed the process of salting meat or fish to preserve it, taking advantage of the chemical properties of salt to draw all traces of moisture out of the meat and add a considerable amount of flavoring at the same time. This process is strikingly similar to the one used by ancient Egyptians to create mummies, and it has proven itself a viable way of preserving organic matter for thousands of years in both applications.
The continual common denominator of needing to dehydrate the food to be preserved stems from the biochemistry of the microorganisms responsible for its decay; without a sufficiently moist environment, these microbes will die off and leave the food essentially incapable of spoiling before water is reintroduced. Cooking food tends to kill off the microbes as well, and so essentially functions as a way to reset the lock on a food’s lifetime, but is rarely a viable method of preservation since most cooking happens in a moist environment of one kind or another.
As common a method as it is, one needn’t kill the microbes entirely to preserve something; there are several means of countering their effects without totally dehydrating whatever it is that you are eating. Modern technology has made the use of preservatives a realistic choice; chemical reagents are added to slow or stop the decaying process, rendering food essentially immortal until the preservatives themselves wear out.
It is possible to preserve some foods by packing them under airless conditions; the microbes that cause spoilage cannot function without auction, and so vacuum packing the food serves as an effective means of stopping their effects. Vacuum-packed food tends to be more expensive than its counterparts, but keeps the food more compact and allows it to be stored with few other measures to keep it fresh.
A less recent development in the food industry is the discovery that hilling food can drastically extend its lifespan; lowering a food’s temperature makes the microbes enter a sluggish, dormant state, allowing the food in which they live to remain edible well beyond what it normally would. Today, this process is accomplished by refrigerators and freezers; in earlier eras, food would be packed in ice and have water poured over it, completely surrounding it in a sub-zero liquid that would rapidly lower the food’s temperature to the appropriate level to maintain freshness.
By putting several of these approaches together, modern science has produced a complex preservation procedure that guarantees food a functionally indefinite lifespan and little or no need to process or chemically treat it to make it edible again. Freeze-drying, as it is called, is becoming increasingly popular for a variety of products, each one intent on being able to stay on the shelves as long as necessary to represent a sale instead of a loss.

When food is freeze-dried, it is first flash-frozen by being placed between two solid pieces of supercooled metal or exposed to a cryogenic agent such as liquid nitrogen; this part of the process originates from the Inuit tribes of the Arctic, who would flash-freeze fish by laying it directly on solid sheets of ice. The entire piece of fish, meat or anything else to be preserved is frozen almost on the spot.
The food is moved to a vacuum chamber where the ice is evaporated; because all moisture in the food is now ice as well, it leaves along with ambient ice from the flash-freezing treatment. The resulting product can be packaged up in an airtight manner and sold as fresh for enormous lengths of time; when water is reintroduced, it will regain its texture and taste in short order, giving you a fresh dish without needing to be anywhere near where the ingredients were produced.
All of this has been put in the context of human food, but it is arguably more important when discussing dog food; dog food has undergone less treatment than human food and tends to be kept around for longer with fewer preservative measures in place. Having a method for preserving dog food is a sound policy for both the dog owner’s investment in the food and the health of their furry friend.

What We Don’t Like About Primal Chicken Formula Grain-Free Raw Nuggets

What We Don’t Like About Vital Essentials Beef Entree Grain-Free Freeze-Dried Mini Nibs

What We Don’t Like About TruDog Boost Me Mighty Meaty Freeze-Dried Raw Beef Booster

Final Verdict: Primal Chicken Formula Grain-Free Raw Nuggets
When it comes to making sure that your pet is getting only the very best nutritional value out of every bowlful of food, this one stands well above the rest for the lengths to which the manufacturer goes in ensuring that all ingredients are 100 percent organic. Not only are there no artificial additives used on the food itself, the meat from which it is made is also kept meticulously chemical-free, from the free-range farm and until your dog is ready to chow down.
The first thing to understand while looking or freeze-dried dog food is that it will not necessarily be in the refrigerated section of the pet store; one of the key aspects about freeze-drying is that it is not a process to cool the food, but rather to dehydrate it, so freeze-dried dog food is likely to be out on the shelves with other meals.
For the same reason, one needn’t worry about storing one’s purchase; unlike fresh or frozen foods that would require refrigeration, these freeze-dried options should stay viable in a corner of your cupboard or in a box with other pet supplies.
A direct result of these meals being freeze-dried is that they will also need to be soaked back to a usable form before being served to your dog; although they aren’t likely to hurt the pooch as is, your dog will find them uninteresting and even unpleasant to eat and will more likely walk away than dig in.
Make sure to consult the packaging to determine the correct quantities of both food and water to use, how long to soak the food or at what temperature, or any other pertinent pieces for someone looking to reconstitute their freeze-dried dog food for use.
Although the review does not go into any great detail, no pet owner can ignore their dog’s size, age, and breed as a factor in deciding what food to purchase; this holds true for any food purchase, as different breeds present changing requirements at various points in their life cycle, and not properly acclimating the diet to the dog can be significantly detrimental to the dog both immediately and in the long term. While the dog might not take any damage from a non-optimized diet, they will not be getting their recommended intake of nutrients, which will prove detrimental in future development.
One natural result of the last point that some people do not take into account is that if they own more than one dog, there may be a need to keep multiple dog foods on hand; people who have more than one dog may be tempted to use only one generic food, but if their dogs are different enough, then one should give serious thought to buying a different food for each one. Even within a single breed, age and physical condition can mean that two otherwise identical dogs need to be fed two very different meals.
Although you’re shopping for your dog, don’t forget that people will have to live with whatever dog food you choose as well; you may not be sitting down to eat the stuff, but take care that it doesn’t contain anything to which those around you display an allergy of any kind. If you start to notice such a reaction, try to isolate the food in question and consider using a different brand; if the person lives in the house with the dog, you may want to take the loss of discarding the cause of the reaction immediately.
During the first few days of serving freeze-dried dog food, especially if you are making a full transition from kibble or raw ingredients, the dog may appear disinterested or even actively reject the freeze-dried food; this is a natural occurrence and can be expected until they learn that the new stuff in their bowl is still edible. You can help them along by employing bowl toppers or meal mixers; these tasty treats are usually made of high-grade meat and are mixed with a bowl of food, making it irresistible to the otherwise picky eater.
It is easy to miscalculate the quantities of food present in a freeze-drying package; between the dehydration and vacuum packing, food can and does shrink considerably as it goes through processing. Take care to get as much as you need, or even a little extra, to make sure that you and your dog aren’t left without anything for the dog to eat while waiting for the next shipment to arrive.
Frequently Asked Questions
These foods proudly proclaim that they are a raw-diet recipe. Dog food isn’t cooked anyway; what does raw diet mean, and what advantages does it offer?
All dog food starts from the same raw ingredients as that of human food; after all, everything comes from the earth one way or another. The human digestive system, though, is not possessed of the appropriate biological components necessary to nourish itself from raw meat; the organ that performs that function, the appendix, is not large enough to handle a steady uncooked diet and can struggle or fail if a human consumes raw meat.
Humans circumvent this by cooking the food in question; the heat of the cooking process changes the proteins within the food (an event known as denaturation) into something that our digestive tracts are more readily able to process. This also makes the food more flavorful, concentrating those chemicals that give our food its taste.
To a dog, though, raw meat presents no problem; nearly every kind of dog can better digest raw meat than humans, and so they are in no need of cooking for their food to be ready. Some dog food, however, is cooked anyway during manufacturing, either to destroy bacteria in the food or to make it easier to compact into kibbles.
Cooking food has a serious downside for dogs and humans alike – denaturation reduces the nutritional content of the food in which it occurs, making any given meal contain fewer nutrients once cooked. A raw diet has never undergone this process, and so still has all the natural nutrients it had originally, with nothing lost to boiling or baking along the way.
Many of these products proudly assert that they are made in the USA. Does this represent any advantage over other countries of origin besides national pride for residents of the USA?
It is perfectly acceptable for a business to take pride in its location; smaller, family-run businesses, such as those behind most of these dog foods, are especially fond of the place where the company was started and how it has lasted so long in a growing market. Marking your products with their point of origin is a harmless and natural way to show your pride in your business, your product, and your home state or town.
There is indeed a more significant element, though, to the many proud declarations of ‘Made in the USA’ that appear on so many of these bags. Pet food made in the USA needs to conform with the rigorous standards set by multiple governmental bodies that oversee the care and treatment of animals in the country; the most prominent of them is the Food and Drug Administration, although there are others along the way.
By learning the many levels of approval needed for both the food’s nutritional content and the manufacturing process, American dog foods have proven themselves to be at least up to those benchmarks before you even order them. The consumer is further protected by the intervention and safeguards of agencies that regulate the conditions in which the feed animals are raised and moved, the amount of chemicals that can be used on the vegetable elements, and more; all of this means that seeing ‘made in the USA’ on a bag isn’t just national pride, it’s an indication of the product’s quality.
My dog seems disturbed by the use of freeze-dried food as opposed to the kibble they were eating before. How can I convince my dog that this food is just as good?
This is a totally natural reaction from the dog; over time, it has learned to distinguish food by the sound and sight of the kibbles instead of the smell or taste of the natural ingredients within. While this habit is useful to you as the owner to stop your dog from going for your plate as well, it can present a challenge when trying to teach the dog that something else is food too.
Start by offering the dog a few bites of the new food in a bowl or on your palm. This will make the dog interested in the new food and inevitably come to taste what it is being given; having done so, it will likely down them in short order and be looking around for more.
Capitalize on this opportunity to give the dog a few more kibbles each time, further reinforcing the idea that these are food and that it should be interested in them. One can also use a few bits of food from the new bag of treats for good behavior, building a positive connection to the new food in your dog’s mind.
At the same time, begin mixing the new food into the old food as the old bag runs down, ideally placing them so that the old food covers the new from sight as much as possible. Your dog will unwittingly eat the new kibbles, acclimating itself to them well before having to rely on them alone.
Picky eaters may require a certain amount of added encouragement to start in on a new brand of kibble; try using a liquid meal topper to add a scent or flavor of particular interest to dogs of the relevant breed or size. Alternatively, you may want to limit access to food while switching to a new brand; the dog will understand that the new food is their only opportunity to eat and will rapidly grow eager to eat even unfamiliar kibble.
Many brands of dog food will include on their bag a scale to illustrate how to properly bring your dog to enjoy the new food in the bag, including the quantities for different sizes of dog and the length of time you can expect it to take. Make sure to follow these instructions carefully; if ill effects are noticed, seek veterinary help immediately.
