3.2 FD technology can also be used for the preservation of various bacterial species
For example, Lactobacillus acidophilus has health-care effects, and there have been more and more studies in this area in recent years. Live bacteria preparations should maintain a high level of viable bacteria before consumption, and many current products cannot effectively prevent the attenuation of the number of viable bacteria. How to increase the amount of viable bacteria and extend the storage period of live bacteria has become a research and development project for live bacteria preparations. technical key. The production of viable bacterial preparations through FD technology is an ideal one among various preservation methods.
3.3 Dehydrated vegetables
Dehydrated vegetables are a relatively popular best-selling food in the world in recent years. They are made by processing fresh vegetables (moisture content 80-95) into dried products (moisture content up to 5~8) To achieve a high degree of freshness (nutritional content 70%, color retention 70%, flavor and good palatability) and refined dishes that are easy to store and transport.
There are three processing methods for dehydrated vegetables: normal pressure hot air drying, vacuum drying and vacuum freeze drying. Among them, the normal pressure hot air drying method is more commonly used, but the quality of its dried products (freshness retention and rehydration properties) is far inferior to that of vacuum drying and vacuum freeze drying. Moreover, with the improvement of people's living standards, consumers are more concerned about the nutrition and convenience of food. Safety has put forward higher requirements, so FD technology has gradually been understood and recognized by people. In the future processing of dehydrated vegetables, FD technology has a tendency to gradually replace normal pressure hot air drying.
3.4 FD soup cubes
FD soup cubes are also a new force in convenience foods that cannot be underestimated in recent years. Among the current convenience food categories, instant noodles occupy the majority of the market share, attracting consumers from all walks of life with their convenience. However, the nutritional value of instant noodles is far inferior to its convenience, which makes many people think of its nutritional deficiencies while enjoying convenience. FD soup cubes can be used as a convenience food alone or can be eaten together with instant noodles. FD soup cube is a convenient soup cube made from fresh soup through FD technology. When eating, you only need to add an appropriate amount of hot water to get a delicious and nutritious soup. FD soup cubes contain vegetables, eggs, lean meat, vermicelli, etc., which are much more nutritious than instant noodles. They can be used as breakfast, lunch and dinner. It is nutritious and convenient, and is especially suitable for children and the elderly. Because it is light and easy to store and transport, it is more suitable for consumption when traveling. It is easy to carry, ready to eat, and has comprehensive nutrition. It is an increasingly growing category of convenience food. In recent years, FD instant noodles have also appeared on the market. It changes the frying process of traditional instant noodles in my country and uses FD technology to dehydrate and dry the noodles, which not only avoids the damage and loss of nutrition caused by frying, but also It retains the original flavor of noodles and can be said to be a green food. Instant noodles are not fried, have a relatively extended shelf life, and have good rehydration properties. They have attracted widespread attention from consumers as soon as they were launched.
3.5 FD milk
Milk is a very important nutritious food in our family life. It can provide rich calcium and protein to the human body. However, considering the short shelf life of milk and the difficulty of transportation, etc. Question, some FD manufacturers in my country have begun research on FD milk. After years of hard work, FD milk has also become a bold attempt. FD milk is made from 250 mL of liquid milk into a milk ball the size of a camphor ball. After the milk ball is brewed and reconstituted with boiling water, you can get a cup of fresh milk with a rich milky aroma. It is reported that France is the only country in the world involved in this invention, which is still in the experimental stage.
3.6 A bold attempt to use FD technology to dry seafood
Sea cucumbers are low-fat, high-protein foods with extremely high nutritional value. However, ordinary drying methods limit the rehydration of sea cucumbers. There are restrictions on sea cucumbers, and there is also a certain loss of nutrients in sea cucumbers. However, after processing with FD technology, almost all the nutrients in sea cucumbers can be retained, and they can be absorbed by the human body to the greatest extent after consumption, achieving the results of other methods of drying sea cucumbers. Incomparable effect. At present, the existing FD seafood products include FD sea cucumber, FD squid and FD clams.
4 The Current Situation and Development of my country’s FD Industry
The above introduction is about the representative FD products that appear in the Chinese market. However, nationwide, my country’s FD industry is still In the early stages of development, the charging area of ??FD equipment nationwide is only about 18,000 m2, and the total annual FD food output is only 1.5×104 t. In terms of loading area, our country is only equivalent to Japan's level in the early 1980s; in terms of output, our country is only equivalent to the United States' level in the mid-1960s. This is in line with the fact that our country is rich in resources and has a large population. The current situation is extremely inconsistent, which also reflects the gap between my country's food industry and developed countries from one aspect. As my country's economy grows year by year and national living standards improve, people will no longer be satisfied with traditional dehydrated and dried food, so FD technology will have great room for development. Experts predict that by 2010, my country will only need high-end instant noodle accessories, which will require about 4×104 tl of FD food. Together with various fast food ingredients, soups, beverages, etc., the annual consumption of FD food will exceed 10×104 tlul. Moreover, 98% of my country's existing FD products are exported, and the domestic FD industry mainly relies on the international market. In recent years, major FD food consuming countries such as the United States, Japan, and Europe have had an increasing demand for FD products. There is an endless stream of foreign businessmen coming to my country to purchase FD products. Currently, the supply of FD products in the international market is still in short supply. situation. Therefore, in terms of the market, whether it is the domestic market or the international market, the FD industry has an extremely broad development space that needs to be explored urgently.
It is understood that the production of 1 kg of FD strawberries can earn 7 US dollars in foreign exchange, which is equivalent to the export of 1 color TV set; the profit of producing 1 tFD of vegetables is more than 5 times higher than that of hot air drying products. It can be seen that FD products have great economic benefits and are a promising export project for earning foreign exchange. In recent years, due to the high cost of processing agricultural products in some developed countries, manufacturing industries have turned to my country. Therefore, we should seize the opportunity and actively adopt joint ventures, cooperation or self-investment to expand the production scale of FD food and promote the development of my country's FD processing industry. Rapid development. At present, many food processing companies in my country have achieved gratifying results in the application of FD technology. Among them, Shandong Yuanyang Food Co., Ltd. is worthy of attention. Its chairman Song Shuxiao has obtained 15 invention patents in 3 years. Breakthrough progress has been made in the field of food processing. The instant wontons invented by him have overcome a problem that Japanese researchers have not solved for many years. In addition, dehydrated grapes and freeze-dried sea cucumbers have also filled gaps in the international market with FD technology.
Our country has rich agricultural and animal husbandry product resources, but our country’s agricultural and animal husbandry products have always been in the original product or primary processing stage, with low technical content, and the FD industry is a high-tech industry with high added value. The emerging industry is suitable for my country's current situation of rich resources, large population and low agricultural and animal husbandry product processing technology.
Vigorously developing the FD industry in fruit and vegetable production bases can not only digest local agricultural product resources, but also earn considerable foreign exchange. At the same time, it solves the employment problem of my country's agricultural population, causing farmers' income to increase year by year and their living standards to improve rapidly. The production cost of FD food is relatively low. As long as suitable FD equipment is used and the optimal conditions for FD production are controlled, high-quality FD products can be produced. FD products are highly profitable and have low risks, so they are worthy of promotion and strong support. Foreign exchange-earning projects have huge development potential and room for development.
In short, the FD industry has quietly emerged in our country and is being widely understood and recognized by people. With the development of science and technology and the take-off of our country's economy, it will definitely lead to the increasing progress and perfection of FD production equipment and technology. I believe that in the near future, FD food will also appear on our daily tables.
