What are the varieties of dehydrated vegetables
When eating instant noodles at ordinary times, there will be a vegetable bag inside. The bag contains dehydrated vegetables, which are artificially dehydrated vegetables, also known as dried vegetables. It is convenient to rehydrate them after soaking them in hot water for a few minutes. There are two common types of dehydrated vegetables:
1. AD vegetables
AD vegetables, also known as dried vegetables, are collectively referred to as AD vegetables when dehydrated vegetables are produced by drying and dehydrating machines. The principle is that the moisture on the surface of vegetables is vaporized and diffused to the air by drying hot air, so as to increase the concentration of the content on the surface of vegetables, form the osmotic pressure difference of the connected inner cells, make the water in the inner layer diffuse and flow to the outer layer, and keep the water vaporized.
During the processing of AD vegetables, a lot of water-soluble vitamins and bioactive ingredients are lost, and the color of vegetables is also prone to darkening, which is one of its major drawbacks
2. FD Vegetables
FD vegetables, also known as frozen vegetables. Dehydrated vegetables produced using a freeze dryer are collectively referred to as FD vegetables. The processing principle of FD vegetables is to quickly freeze the drained material, allowing the remaining water in the material to be converted into ice. Then, under vacuum conditions, the water molecules are directly sublimated from solid to gas, thereby completing dehydration.
Compared to AD vegetables, FD dehydrated vegetables can better retain the original nutritional components, color, and flavor of vegetables, but their processing costs are also relatively high, and are usually used for the processing of high-end vegetables
What are the uses of dehydrated vegetables
The application of dehydrated vegetables is currently mainly concentrated in three aspects:
1. Anti stagnant sales
After a good harvest, some vegetables and fruits may not be sold in a timely manner. In order to avoid spoilage, some farmers choose to dehydrate and process them to increase their storage time. 2. Dried vegetable and fruit snacks
Snacks made from dehydrated dried vegetables and fruits often appear in supermarkets. These snacks not only have a crispy taste and are easy to consume, but also meet the needs of busy populations for vegetables and fruits
3. Convenient food side dishes
The biggest purchaser of dehydrated vegetables is instant noodles manufacturers. Vegetables are indispensable in ingredients. In addition to instant noodles, dehydrated vegetables can also be added to other convenience foods as side dishes.
Dehydrated vegetables are widely used, almost involving various fields of food processing. They can not only be used to improve the nutritional content of products, increase product color and flavor, but also make the variety of products more diversified, greatly improving the food structure of consumers
2. Characteristics of dehydrated vegetables
Compared to other fresh vegetables, dehydrated vegetables have the characteristics of small size, light weight, easy recovery when water is added, and convenient transportation and consumption. When consumed, it not only has a delicious taste and fresh color, but also maintains its original nutritional value. It is easy to store and transport, and can effectively regulate the season of vegetable production.
