Food drying is a modern way of food preserving where food is dried at high temperatures. Drying slows the growth of fungi, yeasts, and molds through the partial removal of moisture. Foods that are dried can be stored for up to 10 years. They retain most of their flavor and nutrient values but do not have as much of a shelf life as fresh foods do. There is no risk of toxic gases or chemicals escaping in the air when food is dried by heat.
It was not always so easy to dry foods efficiently. The process of room drying had some disadvantages. Dried foods had to be stored in extremely controlled environments. Room drying also wasted a lot of food and time. These days, with the help of modern technology, dried foods can be preserved more easily and quickly than in the past kingfoods vietnam.
The most popular dried foods are those that are preserved with water. Dried fruit, such as raisins, dates, and mangoes, are some of the dried fruits that have enjoyed tremendous popularity in recent years. Dried vegetables, such as cauliflower and Brussels sprouts, are now an increasingly popular dried food product. Another dried food that has gained popularity over the years are the nut products. Honey, cinnamon, raisins, and pecans have all become very popular in recent years because of their availability and ease of use.
Dried fruits are now a multi-billion dollar industry. One of the biggest selling items in dried foods stores is the jelly of mangoes. Fruits, such as watermelon and pineapples, are also highly popular. Jelly made from canned fruits and vegetables is also a very popular product.
Dried food preservation methods can be broken down into three categories. The first is airtight packaging using vacuum methods; the second is freezing (frozen) in liquid nitrogen; and the third is oven-frying (cooked). Airtight canning containers are probably the least expensive among the three methods. Drying fruits using oven frying is slow and labor intensive. However, it produces a healthier dried product than canning.
In order to preserve vegetables, meats, and fish, you will need to use the second method, freezing. When fruits, meats, and fish are frozen, they retain very little of their moisture. Some of the best canned fruits and vegetables are freeze dried. Canned vegetables have almost no moisture left in them once they are sealed inside the can; however, they are not as flavorful as fresh vegetables. Vegetables and fruits that are placed in a can are usually destroyed because of the loss of moisture.
