Today life has never been more hectic. Work, study, family commitments, travels; there are several other factors which make it difficult for an individual to take out enough time for cooking a proper meal each day. People look for something fast to eat but at the same time they look for tasty dishes. In other words, people desire to get a meal prepared from food similar to those which are prepared at home.
This is where freeze-drying technology has helped.
Newer technology of food preservation will change the way meals are prepared, packaged, transported and consumed. Consumers no longer have to rely completely on frozen foods and packaged foods because they now have a choice of lightweight food products which have longer shelf-life and also take less time for preparation.
In terms of Indian consumer, this can open up a world of new possibilities. For instance, imagine getting a taste of dishes like dal makhani, rajma or poha while traveling, working overtime or living in hostels without preparing it completely.
We at Appico Foods, Jaipur believe in providing our consumers with a choice of convenient food products along with comfort of their traditional recipes.
This paper discusses the working of freeze-dried technology and its significance in the revolutionizing of the ready-to-eat food industry. This paper also discusses the impact of freeze-drying technology on the Indian food industry.
1. What Is Freeze-Dried Technology?
Freeze-drying is a process used for preserving food whereby most of the water content in the food is removed while maintaining its initial flavor, color, structure, and nutritional value.
While other forms of drying processes involve the use of heat in drying out the food, in freeze-drying, the food is first frozen.
The freeze-drying process basically involves three main steps.
Freezing the food
In this step, the food is frozen to ensure that all the water in the food is in form of ice.
Moisture removal under vacuum
The food, when frozen, is subjected to vacuum. Ice then turns into water vapor without first turning into water. This process is known as sublimation.
Packaging the end product
The last step involves packing the dried food in moisture-resistant packaging materials.
When the product is properly processed and packaged, it can remain shelf-stable for an extended period without refrigeration, subject to the manufacturer's storage instructions.
One of the biggest advantages is that the food can often be rehydrated by adding water. Depending on the recipe, the food can regain much of its original consistency and flavour.
You can learn more about the science behind this process in our guide to freeze-dried food vs. dehydrated food.
2. Why Is Freeze-Drying Becoming Important in the Ready-to-Eat Food Industry?
The desire for convenient food products has resulted in the rise of opportunities for food processors. People need foods that are portable, easy to prepare, and appropriate for various conditions.
While conventional ready-to-eat foods provide convenience, they have drawbacks such as the need for refrigeration or use other means of preserving and packaging.
The freeze-drying process provides an alternative in the removal of most of the moisture content from processed food.
Some of the major factors leading to the popularity of this method include:
Longer Shelf Life Without Refrigeration
Another major benefit of freeze-dried food is the possibility of having a longer shelf life of the product if the product is properly produced and packed in appropriate packaging.
This is because of the removal of moisture, which prevents the occurrence of certain requirements for microorganisms' growth. The packaging helps prevent recontamination with moisture.
Consumers can benefit from this because unopened freeze-dried foods can sometimes be stored in room temperature following the guidelines on the packet.
Nonetheless, the shelf life differs depending on the recipe, processing procedures, and packing method used. It is advisable for customers to strictly observe the recommended best before date and storage instructions for all products.
Lightweight and Easy to Carry
Water plays an important part in adding to the weight of many foods. By eliminating most of this water, freeze drying makes the food lighter in weight.
This comes in handy especially for those who travel a lot, stay in hostels, camp outdoors, or require easy-to-carry food.
This could be beneficial even for the retailers and distributors because lighter goods could be more convenient to transport.
For people who miss their Indian cuisine when not at home, Appico Foods' ready-to-eat Indian meals offer convenient options to explore.
Quick and Simple Meal Preparation
The busy person may not necessarily find time to cook the whole meal since he or she may lack the necessary resources needed to do so.
There are several freeze-dried ready-to-eat meals that one can prepare simply by adding water as per the directions on the pack.
This can take a few minutes only depending on the particular meal being cooked.
In case of a busy work day, a long trip, or even an evening study, it becomes convenient.
3. Bringing Traditional Indian Food Into Modern Lifestyles
One such innovative trend which stands out is the concept of freeze-drying well-known Indian dishes.
Indian cuisine is famous for the variety of flavors, spices, and cooking styles it uses. There are numerous dishes ranging from lentil preparations, rice dishes, and breakfast dishes, which people miss while being away from their native place.
The idea of freeze-dried meals comes handy here.
For example, Appico Foods' Freeze-Dried Dal Makhani The lentil meal is available in an easily accessible manner. Instead of making the curry from scratch, the consumer just has to prepare the food according to the product instructions.
Similarly, Freeze-Dried Kashmiri Rajma provides another option for people who enjoy traditional Indian curries.
Those who prefer a lighter breakfast can explore Appico's Freeze-Dried Poha, while consumers looking for a rice-based meal can consider Freeze-Dried Vegetable Biryani.
These are just some of the ways that food technology may be used on various kinds of meals other than fruits, vegetables, or raw materials for food.
It’s very easy; just making food easier to preserve and to prepare without changing its taste and recipes.
4. Can Freeze-Dried Food Retain Its Taste and Nutritional Quality?
The taste of the product is one of the main worries for consumers when using any packaged meal.
Consumers often associate ready-to-eat food with an altered texture, flavors, or taste that is different from that of freshly prepared food.
It can be possible to solve the problem with freeze-drying since the method of dehydrating food does not require high-temperature treatment.
The product may keep many of its natural qualities such as taste, smell, color, and structure.
Nevertheless, the final outcome will depend on the following factors:
-
The quality and freshness of the ingredients used.
-
The recipe and cooking method before freeze-drying.
-
The processing conditions.
-
The packaging and storage environment.
-
The quantity of water and preparation method used when rehydrating the food.
Nutritional preservation also varies with the type of food and nutrients measured. While some nutrients might be preserved better than by other methods of food preservation, freeze-drying is not a surefire way of ensuring all nutrients will remain completely preserved.
The process and the recipe are just as important as the technology. Even with proper preservation, one must have great ingredients and great cooking to create a good meal.
It is at Appico Foods where the goal is to combine both convenient preparation and traditional Indian recipes.

5. How Freeze-Dried Technology Helps Food Manufacturers
It is not just transforming the customer experience; it is bringing new opportunities for the food industry.
Easier Storage and Delivery
Where products do not need refrigeration when sealed, it becomes easier to deliver and store them as long as the packaging and storage conditions remain intact.
This makes shelf-stable food products adaptable to different retail outlets and logistics channels.
This is also useful in helping companies get closer to consumers living away from their manufacturing centers.
Greater Flexibility in Product Development
A greater flexibility in product development is possible because of freeze-drying technology.
For Indian food manufacturers, it means developing curries, rice products, breakfast items, ingredients, and other such foods.
Instead of just producing regular packaged snacks, the company can create meal-focused and regional food products.
There are differences in how well freeze drying works with certain recipes, meaning every food needs its own processing and testing.
Improved Convenience throughout the Chain of Supply
Food that can be kept on shelves does give the option of convenience for warehouse operators, retailers, and consumers that lack access to proper refrigeration.
However, there is the cost associated with special machinery, energy usage, and good packaging materials that have to be taken into account when assessing the product for commercial success.
The challenge facing food companies is how to achieve convenience, product quality, safety, packaging, and economy.
6. How Freeze-Dried Food Fits Into Everyday Life
This will become clear after considering the circumstances under which freeze-dried foods are needed.
Working Professionals
After spending a whole day attending various meetings and dealing with deadlines, it may not be possible to cook a fresh meal.
It would be good to keep meal options in your house and workplace that are both shelf stable and ready-to-eat.
Students and Students in Hostels
Students might lack either kitchen facilities, cooking utensils, or time to cook. This makes it useful to have a product that requires little preparation, especially if you have limited facilities.
It is also important for you to have access to clean water and prepare the product according to the instructions.
Travellers
Meals that one gets when travelling for many days via road, train, or when away from home may vary.
Unopened lightweight freeze-dried products can serve as an alternative where there are facilities to prepare a product using hot water.
Travellers should also consider the kind of foods prohibited in the destination.
Families
For families whose lives are filled with activities, shelf-stable meals can come in handy during pantry planning.
They may offer one other choice in case it’s not easy to cook, although the lists of ingredients, nutritional information, and personal dietary restrictions should always be taken into account.

7. Does Freeze-Dried Food Need Preservatives?
Freeze-drying assists in the preservation of food mainly through dehydration. Thus, many of the products that fit well can be prepared without adding preservatives based on their composition and processing needs.
Not all foods are safe after being dried because drying alone does not guarantee safety nor kill microorganisms.
Therefore, it is also essential to differentiate between the preservation method and the contents of the food product.
The freeze-dried food item can have salt, oil, spices, or other ingredients as part of its recipe. Thus, consumers need to check the food's ingredient list rather than making assumptions about their nutritional content.
According to the Applico Foods' product description, it makes vegetarian ready-to-eat Indian meals without preservatives. Consumers who require special diets need to examine the ingredients and possible allergens in every single product.
The best way to assess the value of packaged meals is through their ingredients, preparation needs, nutrition facts, and storage guidelines.
8. What Does the Future Hold for Freeze-Dried Ready-to-Eat Food?
The future of convenience foods will consist of various preservation techniques rather than the replacement of all other technologies with one technique.
There is great potential for use in freeze-drying as it provides an opportunity to make light, stable food products that are easy to hydrate. This technology enables food companies to experiment with new concepts that may not be available when sold as fresh or frozen foods.
With the experimentation of food companies in recipes, packing, and manufacturing process, consumers can expect new possibilities concerning various cuisines, sizes, and consumption opportunities.
However, there are still problems that have to be solved.
The equipment is usually expensive, processing consumes significant amounts of energy and the price of the product may be higher than that of some traditional foods. The packing also should ensure the safety of the food during transportation and storing.
The successful use of freeze-dried foods will be possible only if consumers will find the food tasty, of appropriate price and high-quality.
One of the things that will be especially attractive for Indian customers would be an opportunity to get regional cuisine in the form that fits into their schedule.
It doesn’t have to be just a simple snack and not necessarily a ready-to-eat product, but traditional recipes can fit into this category of food products.
9. How Appico Foods Is Bringing Convenience and Indian Flavours Together

Freeze-drying allows combining these two notions that are usually considered separately.
Customers can explore the Appico Foods store to discover available meals and snacks.
Like all other packaged foods, it will not hurt to check the instructions for preparing it, its expiration date, ingredients, and storage instructions before usage.
