Vegetables (fruits) are indispensable food in our daily life. To store them for a longer time and it is very hard, some businesses will process them into dehydrated dried vegetables and dried fruits, also called "dehydrated fruits and vegetables".
Dehydrated vegetables, also known as rehydrated vegetables, are dried vegetables made by washing and drying fresh vegetables to remove most of the water in the vegetables. Simply put, vegetables contain almost no water.
Dehydration technology will keep the original color and nutrients of vegetables unchanged. It is not only convenient for storage and transportation but also can effectively regulate the off-season of vegetable production. For dehydrated fruits and vegetables, it is also very easy to eat dehydrated vegetables, as long as they are soaked in water, they can be restored to their original state, retaining their original color, nutrition, and flavor of the fruits and vegetables.
Dehydrated vegetables were originally due to "space technology". During the Apollo program, NASA invented the technology of freezing and dehydrating vegetables so that astronauts could eat vegetables in space to supplement vitamins. The technology removes almost all the water from vegetables, reducing weight by 20% while retaining 98% of their nutrients.
Will the dehydration of vegetables lose their nutrients?
The answer is: no!
Only in the process of dehydration, some nutrients will be lost, but as long as it is not subjected to high temperature, the chemical components inside the vegetables will not be destroyed, and the nutrients in the vegetables will still be retained in the vegetables!
Process flow: raw material selection → washing and cleaning → peeling → trimming → cutting into a certain shape (particles, flakes) → blanching (hot water blanching) → cooling → quick freezing → vacuum drying → nitrogen-filled packaging.
Dehydrated fruits and vegetables are divided into AD fruits and vegetables and FD fruits and vegetables.
01. AD vegetables and fruits, also known as dried vegetables. Dehydrated vegetables made by drying and dehydration mechanisms are collectively referred to as AD vegetables.
02. FD vegetables and fruits, also known as frozen vegetables. Dehydrated vegetables made from freeze dehydration are collectively referred to as FD vegetables.
80% or even more than 90% of fresh fruits and vegetables are water, and dried fruits and vegetables must be dehydrated, which is equivalent to a concentration process, and the heat will naturally come up. If it is calculated by calories, this 100g bag is not enough. If so, it's almost worth a few pounds of vegetables! (Whether it is dried fruits or vegetables, it is more than 100 grams) Therefore, it is recommended that you do not eat too many dried fruits and vegetables, otherwise, it will cause symptoms such as anger and oral ulcers.
