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

3. Use A Freeze Dryer

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.

7 Cheeses Everyone Should Know About

The fact that there are at least 650 types of cheeses means that there are types that even cheese lovers have not heard of before. These cheeses can be found in different parts of the globe from the cold, temperate regions of Canada to the snow-capped mountainous rural areas of Switzerland to the warm, tropical fields in South Asia. For those who want to know more about the lesser-known types of cheese, these are seven that you should try out soon: Cotija : You may not have heard of cotija cheese before but you may have already tasted it as it is a mainstay on taco and salad recipes. It is derived from cow’s milk, which is aged for three months. Originally from Mexico, it has been compared to feta though it acquires a tangier taste and drier texture as it ages. It is used in its home country as an addition to the soup. Other cooks also mix it in with guacamole and use it to top beans and casseroles. Emmental : A lot of people call it “Swiss cheese” but its name is actually “Emmental.” Emmental is the type of cheese typically featured in cartoons with holes in them. Emmental is especially perfect for fondue and grilled cheese. What is most interesting about Emmental is the process by which it is made. Cows are made to graze in the mountains of the Alps in the southern regions of Switzerland so that they can produce milk later on. The milk curds are the ones used to make Emmental by pressing them firmly together. What is the reason for the bubbles you say? These are actually bubbles of carbon dioxide that were made by bacteria that are consuming the lactic acid. Camembert : The camembert may be one of the most widely produced cheeses in France but it is barely known outside Europe. This is due to the fact that the aging period is only at over three weeks, making it difficult to mass transport in batches to other parts of the world. Camembert is characterized for its mild, almost mushroom-like aroma. It is sometimes eaten as is or deep-fried. A few even do breaded camembert snacks. Manchego : This Spanish cheese is made from milk produced from the Manchega sheep. It has a varied color, depending on the aging period it has, which can range from ivory to yellow. Young manchego cheese can be characterized as creamy and rich though it becomes salty as it ages. It is usually served as is though it is popularly paired with the Spanish membrillo for snacks. Feta : Feta is unusual as cheese as it is among the few that is a combination of two types of cheese. Seventy percent of feta is made from sheep’s milk, with the remaining parts coming from goat’s milk. It mainly comes from Greece and is moist and brined. It tastes great when it is used as a spread on bread. Monterey Jack : This cheese is one of the few kinds of cheese that originated from the United States. It is unique in the sense that it has one of the shortest aging times – only one month. Made from cow milk, it has a mild but buttery flavor. Due to the high level of butterfat in it, it melts right away, which makes it a great way to make cheese dip. It is also sometimes used over chili and casseroles. A thing that you may not realize about Monterey Jack is that it is usually the cheese that is mixed with hot pickled peppers to come up with Pepper Jack cheese. Chèvre : In France, the word “chèvre” mainly refers to any type of goat milk. In fact, the word is literally translated as “goat.” The use of “chèvre,” however, has evolved through time as it moved to other places. Now, the aging time of chèvre has become so varied. For example, in America, chèvre is what people call fresh goat’s milk that is not aged and is served and eaten right away after it is done. French variants of chèvre, on the other hand, are described as lemony and slightly acidic. When you see chèvre sold in markets, you will see that it comes in vacuum-sealed logs, with a few spices and herbs added. Conclusion : If you want to make these popular cheeses, you should have one of the best cheesemakers available in the market. In addition to having a cheesemaker, you may also need a yogurt strainer bag. So, go ahead and have all you need to make these popular cheeses and enjoy the amazing tastes and flavors of cheeses you like.

The Best Red Wine that Suits Your Taste

For a casual wine drinker, wine is usually categorized as white wine, rose wine, blush wine and of course red wine. The supermarket sells many choices for each; we have Vin de table or the cheap but classic wine ranging to the most expensive amounting to thousands of dollars per bottle. Truth be told, most people read the labels but can’t understand it. We know that it is red wine or white wine but we have a little amount of knowledge about the types of wine grapes they use, and that is the most important thing. This is because the wine grape used in manufacturing, predicts and give off the taste, texture, and smell of the wine itself. Well yes, it can be generalized that white wine is mostly this, and red wine is mainly that, and the list goes on. But, if we try to understand and know the wine grape used in production then, it will be easier for us to choose the perfect wine from shelf to shelf. So read on and let’s have a glimpse of which type of wine will mostly tickle your taste buds. The Best Red Wine that Suits Your Taste: Cabernet Sauvignon: If you’re familiar with Currant and black cherries, then Cabernet Sauvignon radically tastes like this. Sometimes, upon drinking you can also taste that green olive and bell pepper feel that adds up to the wholeness of the wine. This is the trademark of Napa Valley and is also considered the primary component of Bordeaux. This wine is grown all over the globe, but only a few can achieve to produce the best Cabernet Sauvignon wine due to many factors like climate, soil component, and of course processing. Thus, each continent has its style of this wine, some tend to have that darker shade, and some have that strong aroma. Cabernet Franc: If you’re more into violets and blueberry, this is the type of red wine grape for you. This is considered the cousin of Cabernet Sauvignon and this is one of the significant classifications of the Bordeaux wine. Compared to its cousin, this gives off that earthy taste, and you can tell it from its aroma, emitting a scent of freshly roasted coffee. Of course, this wine grape is also grown all over the globe. It only varies in the number of tannin contents because of the different climate and topographical conditions during its growth. Also, since additives are combined with this red wine, it can result in a minty, and pungent taste. Pinot Noir: If the flavor of cola, root beer, plum, pale cherry, tomato leaf, and blackberry combined excites your palate, then this is what you are looking for. Pinot Noir is also the significant components of champagne and other sparkly wine during production. For connoisseurs, this red wine is a delicacy. And since it is a delicacy, Pinot Noir requires demanding supervision from winemakers since this type is fragile and prone to weedy flavors if not taken care of properly. It is usually grown in single-vineyard wine in Oregon and California. Merlot: If you like the taste of watermelons, strawberry or plum, then this is your best choice. Merlot is like the middleman of all these types as it doesn’t have that strong feature in its taste, and aroma. It is the purest red wine and the epitome of “Vin de table.” Merlot is best produced in Washington and most preferred red wine during the 1990s, but due to oversupply, over pricing, production of poor and bland quality, it lost its reputation. Malbec: If you’re into sour and spicy impression, then Malbec is for you. This type of red wine isn’t that known in the globe, but it has been the pride and glory of Argentina. Malbec is usually aged in oak barrels that add to its flavor over time. Gamay: If you prefer a fruity, somewhat sweet taste, then look for this wine grape. It usually tastes like raspberry, fresh cherries, and strawberry. Gamay gives off that slight fizz and has the aroma of bananas. Gamay is best consumed when still young if you want to experience that bright, and tangy flavor. Sangiovese: If you are fond of the scent and taste of tobacco leaf, and pie cherry, the search is over since Sangiovese is for you. This type is the main grape in Tuscany and has also been the main component of other well-known wines. Sangiovese is quite acidic compared, but lighter in color when compared to other wine grapes. In Italy, Sangiovese is usually mixed with Cabernet Sauvignon to level off with the later, thus creating the “Super Tuscany.” Besides Italy, Sangiovese is best produced in Walla Walla Valley in Washington, but elsewhere this type is undistinguished and considered dull. Not all supermarkets and local stores are retailers of a vast variety of red wine, so not all stores can satisfy those parched palates. To achieve the greatest experience with red wine, there are online wine merchants who can offer you tons of choices. Sokolin Red Wine is there to help you browse through tons of options coming from all over the globe. When it comes to wine, you can never settle for whatever is in stock.
