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.

History and How to Increase Sales in Your Confectionery Shop

The skill of molding confections is known as Confectionery. What are confections? These are food products that are made of carbohydrates and sugar abundantly. A store that engages in producing and selling these delicacies is called a Confectionery shop. The main target market of these goods is children. Young ones have a big love for candy as they consume them in a substantial number. A confectionery store has different names depending on the geographical area. In Australia, it is known as a lolly shop, a sweet shop in the United Kingdom, and North Americans call it a candy shop. Despite the different names, all of them produce and sell the same goods. Well, there are a lot of ways to increase your sales, but you could try these out and find out just how effective they are. History Initially, confections were made out of honey as sugar was not readily available in the foregone western world. The Romans, Chinese, Egyptians, Indians, and the Greeks used honey to cover flowers and fruits to conserve them and produce sweetmeats in ancient times. Between the 4th and 6th centuries BC, Persians and the Greeks engaged Indians to produce "reeds that produce honey without bees," which is sugarcane. The cane is primeval in Southeast Asia and the tropical Indian subcontinent. Sugarcane agriculture was advanced and spread afterward. With the introduction of sugar, confectioners gradually started renouncing honey in the production of confections. The Indians came up with a mechanism to create sugar crystals. In the local dialect, the crystals were known as khanda, where the name candy originated. Kransekake is one of the ancient confections from Scandinavia. According to Guinness World Records, the most ancient candy shop in the world that is still functioning to date is located in Pateley Bridge village. Pateley Bridge is now a small market town in England. Read more here https://www.bbc.co.uk/bitesize/articles/zm2q4xs. What is in a Confectionery Shop As explained above, a confectionery store engages in producing and selling confections mostly to the kids. The produced confections in a Confectionery store can be fractionated into two, bakers and sugar confections. Baker's Confectionery It is one of the confectioneries and is also known as flour confections. These are sugary foodstuffs that use flour as their major component. After they are made, these confections are baked hence the name baker's Confectionery. They include sweet pastries, scones, cookies, doughnuts, and cakes. However, baker's confections are baked, bread is not considered as a baker's confectionery. You may go through: The Need for Speed-to-Lead in Sales Sugar Confectionery Unlike baker's, sugar confectionery is mainly made of sugar. The most crucial substances used in this category are glucose syrups, sucrose, and invert sugars. A concoction of fructose and glucose, which is turned out by hydrolysis of sucrose, is called invert sugar. Confectioner's glucose is also known as glucose syrups which are intensive, cleansed, aqueous solutions of nutritious saccharides from starch. This confectionery can be divided into two, fondant and boiled sweets. Click here to see how you can start this business. a) Fodant Fondant is tiny sugar crystals in concentrated sugar syrup. It is used in embellishing cakes and as a creamy filling in biscuits and chocolates. Fondant is manufactured in two ways. It is an inverting agent and refrigerating speedily while riveting or mixing sugar solution with glucose syrup then boiling them. The sugar in fondants is in a crystalline state. These foodstuffs include coconut paste, chocolate centers, marzipan, fudge, and chews. The articulation of fondant is made up of 22% w/w water, 16% w/w confectioner's glucose, and 62% w/w sucrose. Sucrose is the primary component in this formulation. b) Boiled Sweets Boiled sweets are made by boiling water and sugar at extremely high temperatures ranging between 150 and 166 degrees Celsius. When boiling, the water evaporates, and a translucent mass is formed on cooling. In boiled sweets, their sugar is in a glassy state as it is hard-boiled. This confectionery includes barley sugars, caramel, fruit drops, toffee, butterscotch, and hard gums. The articulation of boiled sweets comprises 20% w/w water, 32% w/w glucose syrup, and 48% w/w sucrose. Three Essential Tips on How to Increase the Volume Sales in Your Confectionery Shop The core obligation of any business enterprise is making profits. A huge amount of gain is obtained through more sales for your confection. So how do you increase the volume of your sales? 1. Location The most fundamental factor in this business is where you set up your shop. Children are primary consumers of confections as they take them in huge numbers. To escalate the number of your sales, your shop should be set up in a location where there are more children than adults. An outlet erected in an area where kids are innumerable will make more sales than the other in a setting with scarce younger ones. A store that is put up in an area where there are more adults than the kids will hardly make sales as the main market target of confections is youngsters. 2. Delivery Services The world is evolving so are the buying behaviors from customers. Many people do not like making long queues to be served. Instead, they prefer home delivery services. With the pandemic, many people refrained from going to stores physically to contract the virus in your maneuvers. Many people are adopting online shopping where you order goods online, and the buyer delivers at your doorstep. If you can incorporate delivery services, you will attract the attention of potential customers who do not like going out to the stores. This increases the volume of sales, which means more profit. 3. Social Media The most convenient way to market your products in the 21st century is through social media. There are a million users of social media all over the world. Advertisements of your shop can be run on Facebook, Twitter, Instagram, Tiktok, LinkedIn, to mention a few. Through social media, you can reach many potential customers for your product in the comfort of your store.

Hummingbird Food Recipe: How To Make Hummingbird Nectar?

It always feels good to see a hummingbird in your garden. To see more of them in your garden, you can keep hummingbird nectar/food in a jar in your garden. In fact, with a simple hummingbird food recipe, you can make their lives easier. All you need is a few simple ingredients. In this article, you will learn how to make hummingbird food with simple ingredients. Apart from that, this article also discusses hummingbird nutrition and the steps you can take to set up your bird feeder. Finally, you will learn how to attract more hummingbirds to your garden. Hence, to learn more, read on to the end of the article. Understanding Hummingbird Nutrition There are a variety of food options a hummingbird needs to meet its nutrition. Although they are one of the smallest birds in the world, they burn a lot of their calories by fluttering their tiny wings. Generally, a hummingbird flutters its wings 90 beats per second to maintain its momentum. Hence, you can see that hummingbirds need to eat a lot. In fact, to satisfy their daily calorie requirements, these birds even consume half of their body weight. Basically, they feed on bugs and nectar every 10-15 minutes. Also, they visit 1000-2000 flowers per day. The following are the things that hummingbirds feed on: 1. Nectar: This is the primary food source of hummingbirds. Basically, it consists of 20% sugar and 80% water. Generally, hummingbirds get their nectar from cardinal flowers, bee balm, salvia, and petunias. 2. Insects: For their protein needs, hummingbirds feed on insects. This is also a source of fat and salt for hummingbirds. In fact, nectar does not provide those nutrients. Basically, hummingbirds hunt insects by finding them from flowers, leaves, or tree bark. Sometimes, they also attack insects midair or pluck them from sticky saps. 3. Spiders: Generally, hummingbirds also feed on spiders for protein. However, they are generally small spiders. 4. Tree Sap: When the amount of nectar is low, hummingbirds drink tree sap from tree bark. Generally, woodpeckers drill wells on tree barks to get tree saps. Hummingbird Food Recipe Basically, by offering hummingbird nectar, you can help them with their post-workout meal. Hence, follow the below hummingbird food recipe to make nectar: Ingredients The following are the ingredients you need to make hummingbird nectar: Filtered Water: 4 Cups Regular White Sugar: 1 Cup (If possible, use organic sugar for the recipe) Procedure Here are the steps you must follow to make hummingbird nectar: 1. Get four cups of water in a saucepan and bring it to a boil. 2. Once the water reaches the boiling point, take the water off the heat. Add sugar to the boiling water. 3. Stir the mixture until the sugar completely dissolves in the water. 4. The nectar is ready. Now, you must let the nectar cool completely. 5. Get a hummingbird feeder and place the mixture inside the feeder. Make sure to hang the hummingbird feeder outside (in your garden) to attract hummingbirds. Essential Factors To Consider The following are some of the major factors you must consider before you start making nectar with the hummingbird food recipe: Make sure to change the nectar every four days with a new nectar. This will ensure that the nectar is fresh. Also, remember not to use food coloring in the nectar. Let it be as natural as you can. Regularly check the bird feeder every time you change the nectar inside it. Look whether there is a gray mold inside the feeder base or not. Also, check whether any ant has crawled inside the feeder to consume sugar water. If you check any dirt or ants inside the hummingbird feeder, throw the bird food away. Basically, it is not good for the birds to drink dirty nectar. In fact, there is a high chance that the birds will not feed on the nectar anyway. To clean the feeder, rinse it with warm water. Then, put some bleach into the water inside. This will allow you to clean the feeder with a brush easily. Once you clean the feeder, rinse it thoroughly with fresh water. Moreover, allow the water to dry. After that, please fill up the feeder with food and place it outside. Enhancing The Hummingbird Experience Enhancing the hummingbird experience, you can attract more hummingbirds to your garden/balcony/porch. The following are some of the steps you must follow if you want to enhance the hummingbird experience: 1. Change The Food Regularly Make sure to change the food every 3-4 days. This is because nectar spoils quite fast, especially when the weather is hot. In fact, if the weather is above 30 degrees Celsius, make sure to change the nectar regularly. Also, make sure to keep the feeder in the shade. This will prevent the sugar from fermenting. 2. Use The Right Amount Of Ingredient You can make hummingbird nectar with just water and sugar. However, you must ensure the water-to-sugar ratio is 4:1. Then, boil the water and add the sugar. After that, mix them until the mixture is perfect. After that, you must let the mixture cool before you add it to the feeder. 3. Avoid Honey Generally, honey can ferment fast and becomes a great place for mold to grow quickly. Moreover, they can be sticky and get on the feathers of hummingbirds. Hence, it is better to avoid honey. 4. Add Another Feeder Although hummingbirds are small and cute, they can be incredibly aggressive and territorial when confronting other hummingbirds. Hence, to avoid conflict among hummingbirds, it is better to add a second feeder if you want to ensure every hummingbird gets the opportunity to have the nectar. 5. Clean The Feeders Make sure to clean the feeders every week. Moreover, if you have hot weather around, clean the feeders twice every week. While you clean, ensure the vinegar-to-water ratio is 1:4. Also, rinse the feeders well before you refill. Furthermore, while rinsing, do not use dish soap. This is because they can leave harmful residue on the feeders. Setting Up Your Hummingbird Feeder The following are the steps you must take to set up your hummingbird feeder: Make the nectar by checking the hummingbird food recipe in the previous section. Hang the feeder in your garden at the start of spring. Generally, hummingbirds migrate through your area in the spring. Also, leave the feeder up after the hummingbirds migrate in the fall. Hang the feeder in a place where it is visible for hummingbirds to see. Also, make sure to place the feeder in an area where you can have a good look. Clean the nectar every 3-4 days and clean the feeder thoroughly each time you change the nectar. This way, you can prevent dust and mold from getting into the feeder. Sugar water is safe and helpful for hummingbirds. Basically, it is quite similar to the natural nectar that hummingbirds find in flowers. If you want to make your own feeder, use an old spice container, bottle, mason jar, or wine bottle. Attracting More Hummingbirds Here are some of the major ways you can attract hummingbirds to your garden: 1. Offer Hummingbird Food/Nectar: If you make sugar water and keep it in a feeder in your garden, you can attract many hummingbirds in your area. To make this item, you can see the hummingbird food recipe above. 2. Keep Water: Generally, hummingbirds also like to bathe. Hence, you can keep some water in a pot/jar to allow hummingbirds to access water for bathing and drinking. 3. Perch Area: You can leave small branches and sticks on your trees and plants. This will allow hummingbirds to perch on. 4. Plant Flowers: There is no alternative to pure nectar that flowers have. Hence, this attracts hummingbirds a lot. For instance, you can use hummingbird sage, honeysuckle, bee balm, and more. Also, you can add other types of flowers to your garden. 5. Keep Other Animals Out: If you have a pet cat/dog in your home, keep them inside. This is because they can bother hummingbirds or even end up killing them. 6. Avoid Pesticides: Pesticides are repellants for hummingbirds as well as insects. Hence, make sure not to use them or use them minimally. Make Your Hummingbird Food Now Now, you can make hummingbird nectar with the help of the hummingbird food recipe in the article. However, make sure to change the food every 3-4 days. Also, ensure to clean the jar every time you change the food. This way, you can ensure clean food for hummingbirds. Do you have more suggestions on how to make hummingbird food?
