Natural occurring vegetables cannot stay fresh and edible for many days and would eventually deteriorate. To keep the sustenance quality from fading, techniques and methods are used to preserve vegetables, like dehydration and freeze drying.
Since vegetables are important for a healthy lifestyle and have a short lifespan. Freeze drying is a method through which a vegetable can be dried or dehydrated by freezing. The moisture converts into ice and the food is preserved. The freeze drying for vegetables uses temperatures as low as -29oC. Afterwards, when heat is applied, the vegetable then returns to its normal condition. It’s a complex procedure that requires skill and knowledge because vegetables are delicate and seasonal, so people should be careful before using this method for preservation.
Freeze dried vegetables have the same benefits as other methods. The original color, aroma, freshness, and shape are retained and nothing is affected, but the taste might differ as it doesn’t contain preservatives or additives to keep the taste fresh as new. Unlike low heating dehydration, freeze drying allows people to preserve precooked vegetables or meals also and the reason why people prefer it because it can be rehydrated by adding water and the meal would be ready in some minutes.
Freeze drying ensures nutritional content stays the same. This is a complex method but it’s easy if perfected. Vegetable have a limited lifespan and it strives on nature. With sophisticated dehydration methods moisture levels reduce to 2%-3%, plus storage life increases to several months and years depending on the method used. However, the right storage conditions are important because freeze drying require specific temperature for the vegetables to store effectively.
Not all foods can be freeze dried but most vegetables can, including green beans, broccoli, cabbage, carrots, and celery, sweet corn, mushrooms, and onions, sweet and garden peas. Vegetables are dehydrated to improve storage consistency as well as maintain energy content plus it also helps in minimizing packaging costs and transportation weight. The reason why vegetables are preferred dry is because people prefer storing seasonal vegetables and using them when needed.
Freeze dried vegetables and other methods are used for storing and preservation. The reason why these methods are important is because it can help in times of crisis and emergency, but many people prefer storing vegetables because it can benefit them when there is a requirement. The shelf life of these methods is 15 to 20 years if commercially produced and packaged according to the concept.
In terms of health benefits as stated above, freeze dried vegetables are ideal because the nutritional value remains the same and the quality is better than other dehydration methods.
