Moreover, you will also learn the benefits of freeze-drying and essential tips to freeze-dry your food successfully.

Hence, to learn more, read on to the end of the article.

Understanding Freeze Drying

Freeze drying is a process where you remove water from a food material by freezing it. Then, you turn the ice into vapor by putting the item under pressure. Hence, you can see that this process is a dehydration technique where you sublimate the water in a product.

It means that the water content in your product changes from a solid state to a gaseous state (sublimation). Here, the water does not turn into liquid.

Generally, this method is helpful when you want to preserve any perishable materials. Here, the goal is to extend the shelf life of the material. In this case, you freeze the material and reduce the pressure. Then, you add heat to allow the frozen water in the food (material) to change directly to vapor.

How Does Freeze Drying Work?

Freeze drying consists of three stages: freezing, sublimation, and desorption.

Here is an explanation of the three stages:

1. Freezing

This process involves freezing the food at a very low temperature. Generally, you have to freeze to -30 to -50°F.

2. Sublimation (Primary Drying)

In this stage, you have to pass mild heat over the frozen material while the material is under vacuum. Hence, the ice crystals vaporize into water vapor. After that, you remove the water vapor with the help of a vacuum pump.

3. Desorption

This is the second stage of drying. Here, you have to remove all the remaining moisture from the surface of the food.

Benefits Of Freeze Drying Food

The following are the major advantages of freeze-drying that will benefit you a lot:

Generally, the foods that you freeze-dry retain up to 97% of their nutritional value. For instance, the food retains vitamins, minerals, and antioxidants.
Those foods have a long shelf life. Moreover, you do not need to store it in cold chains.
Once you freeze-dry your food, you will end up removing 98% of its water content. Hence, you will reduce its weight by 90%. Thereby, it will be easy for you to carry that food on camping and backpacking trips.
Freeze-dried food is easy to prepare. This is because you just have to add water to rehydrate them. Moreover, the shape and size of the food remains intact. Also, freeze-drying helps in preventing the growth of pathogenic organisms.
You can preserve a wide range of foods with freeze-drying. This includes meat, fish, fruits, vegetables, eggs, ice cream, and more.
When you freeze-dry food, it does not get brown or caramelize. However, this is quite common when you dry food traditionally.

How To Freeze Dry Food At Home?

Here are the steps you must follow to freeze dry food at home:

Wash your food items that you want to freeze-dry. Also, remove dirt and residues from the food. This way, you can ensure food safety.
Cut your food into small pieces. This way, you can make the freeze-drying process faster.
Place your food on a flat tray. Moreover, make sure to spread the food evenly. Basically, if you spread your food properly, you can freeze the food evenly.
Place your food in your freezer, and set the temperature correctly. Then, place the food in your freezer for two weeks. Actually, you need this time to remove the moisture in the food.
After the completion of two weeks, remove the trays from the freezer. After that, quickly place the food items in airtight bags. Make sure to take out one tray at a time to ensure that the food does not rehydrate.
Make sure to place the food bags in the freezer, and also in a cool, dark spot.
Check the food after a couple of days. This way, you ensure whether all the food is dried-up or not.

Tips For Successful Freeze Drying

The following are some essential tips by following which you can successfully freeze dry your food:

1. Preparing the Food

Harvest the food produced when it is ripe. Then, wash the food, remove the damaged parts, and prepare it as desired. This is because if you cut your food into small pieces, it will dry faster.

2. Arrange the Food

Place your food on a tray and arrange it into pieces. Also, make sure to place those pieces in such a way that they do not touch each other.

3. Use A Freeze Dryer

With the help of a freeze dryer, you can automatically lower the temperature. Moreover, a freeze dryer also helps you to create a vacuum.

4. Store The Food

Once you freeze-dry your food, store it in an airtight container. Also, you can store it in a bag which you can vacuum-seal it.

5. Cook Raw Foods:

One of the drawbacks of freeze-drying is that it does not kill harmful bacteria. Hence, you must cook freeze-dried foods thoroughly before consumption.

Common Uses For Freeze-Dried Ingredients

The following are some of the common uses of freeze-dried foods:

Works as essential food supplies at times of emergencies.
They have a long shelf-life and you can use it to maintain food quality.

Great Health Benefits You Get From A Protein Coconut Bar

Have you ever eaten a protein-based coconut bar and tasted just how satisfying they are? Offering flavors that take your mind to the sun-drenched beaches of the Caribbean, coconut products like these get your mouth watering when you know you’re about to take one out of your day bag and eat it. It’s one of life’s little pleasures. As a low-carb, high-fiber snack, it’s great for bedding down your hunger, but did you know that the humble coconut offers a bunch of health benefits? Well, they do, and by reading on, you’ll understand just what a wise move including them in your diet really is. The fruit of the palm tree is cultivated around the planet, being used in many different types of cooking and health-food products. As we’ll see in a moment. However, the range of body support this natural food source provides is surprisingly extensive. Ways The Coconut Bar Helps The Body So, aside from the delicious taste, what exactly do coconut products like these do for your health? We’re glad you asked, and here are five ways that they assist… 1 - Bacteria-Fighting Power One of the first great things about your average coconut bar is that it’s able to prevent the growth of particular strains of bacteria. Studies have shown that coconut is particularly helpful as oil, at the same time stemming the growth of bacteria like Streptococcus. Since coconuts are naturally antiviral and antibacterial, they can actually help you safeguard your immune system. A hefty immune system is critical for helping you prevent diseases as well as illnesses. 2 - Packed With Nutrition Coconut is different from many other types of fruit in that they contain mostly fat and not carbs. They are also known to contain a range of vital minerals, as well as B vitamins. Also on offer is manganese - something that’s great for supporting your bones. Copper and iron also exist in coconut, boosting the health of your blood vessels. A coconut bar is packed with satiating fiber as well as digestion-friendly ingredients. It never fails to provide minerals such as iron, zinc, magnesium, copper, and manganese. 3 - Blood Sugar Stabilizing Being low in terms of carbohydrates means that coconut does not cause those blood sugar spikes you get after a typical candy bar. As such, they help to keep your blood sugar levels nice and stable, and the fruit is even thought to be beneficial in preventing insulin resistance - a problem that causes misery for many. A study found that HDL cholesterol levels improve significantly on consuming coconut oil for 8 straight weeks. It also enhances triglyceride levels and ultimately reduces blood sugar. 4 - Free Radical-Busting Free radicals are elements in our environment that cause cell damage. We’re talking about things like pollution and stress, and again, coconut comes to the rescue with its innate antioxidant compounds that hold them at bay. Battling them in this way helps to keep you looking younger and feeling great. Coconut, in any form, has hydrating properties. Electrolytes in it help to hydrate and regulate the fluid balance in our body. Moreover, they also help regulate muscle contraction and blood pressure. How To Choose The Right Coconut Protein Bar? Protein bars are not just snacks, they are the prime energy sources for fitness freaks. While choosing the right one might be daunting, the process should never go unnoticed. Thus, the last thing you would want is to select the wrong coconut protein bar for yourself. Here are some tips to opt for the right protein bar enriched with the goodness of coconut. Check The Protein A coconut bar offering 10 grams of protein, at least, in every serving might just be the right one for you. Proteins help the body to build muscles extensively and also recover after rigorous exercise. Further, it enables the stomach to remain full in the middle of meals and fulfills cravings. The Carbohydrate Factor A coconut bar offering carbohydrates of less than 10 grams is excellent for your health. If that amount exceeds, chances are you will have an increased fat amount in the body. This further results in more carb cravings which are not good for your fitness. Sugar A coconut protein bar offering more than 6-8 grams of sugar on each serving is fine. Manufacturing companies usually add sugar alcohols and artificial sweeteners to enhance the taste. But these added sugars take a toll on your health. In a coconut protein bar, avoid sugar alcohols such as mannitol, erythritol, and sorbitol, to name a few. Cut Down Fats Search for coconut protein bars that have increased healthy fats and reduced saturated fats. If your bar has trans fats, it is best to avoid it. Healthy fats present in protein bars consist of nuts, coconut oil, seeds, and nut butter. Always search for a coconut bar that has no trans fat, as it can affect your health significantly. Calories Last but not least, you will have to consider the calorie factor of your coconut protein bar. For men, a protein bar must consist of calories between 170 to 250 per serving. On the other hand, a coconut bar should have 140 to 200 calories in each serving. Considering this might help you reap significant health benefits. A Regular Coconut Bar Is A Great Way To Stay Healthy! So, as we can see, the coconut is a bit of a hero when it comes to human health. Busting free radicals, stabilizing your blood sugar, fighting bacteria, and supplying you with essential minerals and vitamins, it’s one of the best types of snacks you can put in your body. One thing is for sure, you don’t get this kind of body support from a candy bar, so why not consider switching to something that’s no less tasty but so much better for you in the long run? Like the sound of something sweet without the guilt? It would seem coconut protein bars might just be the answer!
