In the past, people only paid attention to food and clothing. Nowadays, with the rapid development of the economy, consumers' dietary concept has changed a lot, and more attention is turned to food health and safety. Fresh fruits and vegetables are an essential part of a healthy diet and provide the body with a variety of vitamins. In recent years, convenient and healthy fresh-cut fruits and vegetables have occupied a place in the market. Therefore, improving the processing technology and preservation technology of fresh-cut fruits and vegetables is conducive to ensuring food safety and promoting the healthy and orderly development of the catering industry.
At present, the fresh-cut fruits and vegetables launched by supermarkets are fresh, diverse and well-balanced, and are increasingly favored by consumers. The basis for determining the quality of fresh-cut fruits and vegetables lies in the selection of raw materials. After screening, the fruits and vegetables are subjected to the second processing process, that is, fruit and vegetable cleaning. In daily life, people mostly use flowing water to wash fruits and vegetables. This method can only remove dust and impurities on the surface of fruits and vegetables, but it is powerless to stains such as fruit wax and pesticides.
Therefore, professional fresh-cut fruit and vegetable factories have adopted fruit and vegetable washing machines
one after another. At present, the fruit and vegetable washing machine adopts ultrasonic technology, which combines ultrasonic waves with turbulent flow to achieve fruit and vegetable cleaning and remove pesticide residues. In addition, there is also a fruit and vegetable washing machine with active oxygen purification technology, which decomposes a large number of high-strength oxides through the action of oxidation and plasma, destroys the molecular structure of the agricultural residue film, and can remove pesticides, insecticides and fresh-keeping on fruits and vegetables. chemicals and other harmful substances.
The cleaned fruits and vegetables need to be cut according to the corresponding standards. The correct cutting method not only helps to prolong the shelf life of fruits and vegetables, but also improves the taste of fruits and vegetables themselves. The automatic fruit and vegetable cutting and processing equipment not only completely removes the peel and core, but also ensures the finished product appearance of freshly cut fruits and vegetables. In addition, in order to avoid the perishability of fresh-cut fruits and vegetables directly exposed to the air after slicing, the fruit and vegetable cutting equipment is operated at low temperature throughout the process, which can effectively avoid the oxidation of fruits and vegetables and improve the effect of locking freshness.
The processed products need to go through the stages of storage, transportation, and sales, which requires the preservation of fresh-cut fruits and vegetables. The current preservation technologies mainly include low-temperature refrigeration preservation, vacuum preservation, preservative preservation and film preservation. The vacuum preservation technology is a safe, harmless, efficient and fresh preservation method by slicing fruits and vegetables into an airtight container, and using an air pump and other tools to drain the air in the container, so that the fruit and vegetable slices are kept in a vacuum environment.
The pace of life is getting faster and faster, and fresh-cut fruits and vegetables are a good choice for consumers, enabling people to enjoy fresh and healthy food conveniently and quickly. At the same time, with the advancement of science and technology, people's requirements for fresh-cut fruits and vegetables are getting higher and higher, and they begin to pursue the freshness and taste of fruits and vegetables on the basis of no deterioration. Provide consumers with a better consumer experience.
