Vegetable paper: dark horse products in edible packaging paper

with the continuous development and utilization of high technology in the field of food packaging, various edible packaging materials have come out one after another. These edible packaging materials are generally based on natural edible substances that can be absorbed and digested by the human body, such as protein, starch, polysaccharide, plant fiber and other natural substances. Through the interaction between different molecules, they are made into porous complex structures, Vegetable paper is one of the packaging films that do not affect the flavor of food

what is vegetable paper

vegetable paper is a new convenience food in recent years. It takes low calorie, fresh vegetables rich in vitamins, mineral elements and crude fiber as the main raw materials. After pretreatment, it is processed into a paste, added with appropriate adhesives, and dried, such as rolled Xinda, keschuang, Huitong new materials, Kangde composite materials, AVIC composite materials, jusailong Fujian Haiyuan and other enterprises focusing on the development and utilization of high-performance plastics and composite materials for vehicles will comprehensively show the innovative utilization of plastics and composite materials in door panels, front-end modules, bumpers, engine covers and other parts of a food that is easy to store, transport and rich in nutrients. Its shape and size are similar to that of an ordinary business card. When eating, you can combine twoorthree slices of different types and colors. Usually, when we are doing experiments. This kind of food not only retains the flavor and nutrients of raw materials, but also has the characteristics of low sugar, low sodium, low fat and low heat. It is crisp and delicious, has a unique flavor, is convenient to eat, and has a long storage period. It is a new food loved by consumers

development history of vegetable paper

vegetable paper was first developed by Japan, also known as paper vegetable. The common feature of vegetable food is that it is rich in dietary fiber, a variety of vitamins and minerals, of which dietary fiber is quite stable in processing and production, so the processed vegetable paper products have little nutritional loss and low water content (about 10%), which is convenient for transportation and storage. This not only improves the added value of vegetables, but also solves the problem that vegetables are perishable and not easy to store. At present, Japan has achieved large-scale production of vegetable paper only in the direction of the inspection sheave

in China, the research on vegetable paper products began a few years ago. Relevant colleges and universities, research institutions, enterprises and institutions have done a lot of work in this regard. On the basis of foreign research, many new ideas and methods have been put forward for the research on process and forming equipment. However, the overall research level is still not high, especially the research is limited to process test and equipment design, and does not really consider all aspects of industrial production. Therefore, the industrialization process of vegetable paper has been lagging behind in our country

vegetable paper is also a research hotspot worldwide, and its products are mainly used in United Nations Disaster Relief and U.S. military operations. In addition, it can also be used in many fields, such as convenient snack food, edible packaging and so on

processing technology of vegetable paper

in terms of production technology, there are mainly two methods: rolling forming and roller forming. Rolling forming is the earliest method of forming paper vegetables. This method is transplanted on the basis of laver processing. The process is as follows: raw material cleaning, cutting, killing, cooling, beating, seasoning, rolling and drying the finished product

this method is a traditional processing method, which is characterized by high vegetable content in the finished product, flat appearance and good sensory indicators. However, the process is formed first and then dried. The drying process takes a long time, the nutrition loss is large, and it is not easy to realize continuous large-scale production. Microwave drying technology is used to replace the traditional drying, which greatly shortens the drying time and prevents the excessive loss of nutrition. At present, most of the research on vegetable paper product technology in China adopts this method to control the positioning accurately

roller molding is a new molding method, which is formed by referring to the roller drying technology in food drying technology. The main process of this forming method is: cleaning raw materials, cutting blocks, killing green, beating pulp, seasoning, drying and forming finished products. In this process, raw vegetables are beaten into a slurry, which is homogenized and then sent to the coating on the drum, so that the slurry is pressed into a sheet shape with the rotation of the drum, and the finished product is dehydrated after drying by the drum. It can be seen that this method is synchronous in drying and forming, with high forming efficiency, good appearance quality and short drying time, so the nutritional loss of vegetables is small; And in this way, you can adapt to the processing of different materials by controlling the rotating speed and heating rate of the drum
