Fruit and vegetable processing technology.
Fruit and vegetable processing is a means for human beings to preserve and process fresh fruits and vegetables, and its history can be traced back to ancient times. With the development of society and the improvement of people's living standards, the fruit and vegetable processing industry has also developed rapidly and has become an important part of the food industry.
Fruit and vegetable processing technology includes a variety of technologies and methods, the most common of which are canning, drying, sugaring, pickling and quick-freezing. Each of these processing technologies has its own characteristics and scope of application, which can meet the needs of different consumers.
Canning is to put fresh fruits and vegetables into a clean jar, add an appropriate amount of salt water or other liquids, and then seal and sterilize them to achieve the purpose of preservation and convenient consumption. Canned food has a long shelf life and retains the nutrients and taste of fruits and vegetables.
Drying is to dehydrate fresh fruits and vegetables to reduce their moisture content to a certain level, so as to prolong the shelf life and facilitate storage and transportation. Common drying methods include natural drying and artificial drying, such as sun drying, baking, etc. Dried fruits and vegetables are lightweight, easy to carry, and easy to preserve.
Sugar is to put fresh fruits and vegetables into the sugar solution, after a certain period of maceration and heat treatment, so that the water in the fruits and vegetables is reduced, and the sugar content is increased, so as to achieve the purpose of improving the sweetness and preservation of fruits and vegetables. Candied fruit and preserved fruit are representative products of sugar.
Pickling is to put fresh fruits and vegetables into salt, vinegar, sauce and other pickling preparations, through the pickling process to reduce the moisture in the fruits and vegetables, and at the same time increase salt, acidity or spicy taste, in order to achieve the purpose of preservation and flavor improvement. Kimchi and sauerkraut are all typical products of pickling.
Quick freezing is to quickly cool fresh fruits and vegetables below the freezing point, so that the water in them forms ice crystals and quickly crystallizes, so as to prolong the shelf life and maintain the original nutrients and taste. Frozen fruits and vegetables can be stored for a long time and can be easily transported to various places.
In addition to the above-mentioned common processing techniques, there are also some special processing methods, such as vacuum frying, ultra-high pressure treatment, etc. These methods are able to provide consumers with a more diverse range of product choices.
Fruit and vegetable processing technology has a wide range of applications and can be selected according to different types of fruits and vegetables, consumer needs and market conditions. Through reasonable processing technology selection and parameter control, the original nutrients and taste of fruits and vegetables can be effectively maintained, and the quality and added value of products can be improved at the same time.
The development of fruit and vegetable processing industry is of great significance to meet people's growing food demand and improve the added value of fruits and vegetables. With the advancement of science and technology and the continuous change of market demand, the fruit and vegetable processing industry will continue to develop and innovate to provide consumers with more abundant, healthy and delicious food choices.
