Edible fruit preservatives developed in the United Kingdom into an edible fruit preservative. It is a semi-transparent emulsion prepared from sucrose, starch, fatty acids and polyesters. It can be sprayed, brushed or impregnated on the surface of fruits and vegetables such as citrus, apple, watermelon, banana and tomato, with a shelf life of up to 200 Days or more. Because this preservative forms a layer of sealing film on the surface of the fruit, it can prevent oxygen from entering the interior of the fruit, thus prolonging the ripening process of the fruit and serving as a preservation effect. This preservative can be eaten with fruit.
Electronic preservation machine abroad has emerged an electronic preservation machine. Put this kind of machine in the fruit and vegetable storage room, make the fruits and vegetables stored inside fresh and picked up as early as 75 days, the good fruit rate reaches more than 95%. This preservation machine uses the negative oxygen ions and ozone generated by the high-voltage negative electrostatic site to achieve the purpose of preservation. Negative oxygen ions can passivate enzymes in fruits and vegetables for metabolic processes, thereby reducing the degree of respiration of fruits and vegetables, reducing the formation of fruit ripening agent - ethylene; ozone is a strong oxidant, but also a good disinfectant and sterilization Agents can kill and eliminate microorganisms and their secreted toxins on fruits and vegetables, inhibit and delay the decomposition of organic matter, thereby prolonging the storage period of fruits and vegetables.
High-temperature treatment preservation method Britain has invented a bulb vegetable storage technology. This technology uses high temperature to inhibit the germination of bulb vegetables. The storage room temperature is controlled at 23 °C, and the relative humidity is maintained at 75%, so that long-term preservation and storage can be achieved. However, under such temperature conditions, vegetables are prone to produce saprophytic fungi and cause lesions. At present, the United Kingdom is studying how to control this saprophytic fungus. According to reports, onions can be stored under these conditions for 8 months.
Decompression Treatment Freshness In France, there has been a decompression-free storage of fruits and vegetables in recent years. The principle of this preservation method is mainly the application of reduced pressure, with the low temperature and high temperature, and the use of low-pressure air circulation and other measures to create a favorable storage environment for fruits and vegetables. The low pressure of the storage room is generated by vacuum pumping the indoor air, and the low pressure is controlled below 100 mmHg and the minimum is 8 mmHg. The relative humidity in the air is controlled by a humidifier installed in the room, which is generally more than 90%. This method reduces the oxygen content in the room during the pumping process, keeps the respiration of the fruits and vegetables at the lowest level, and also eliminates some of the indoor gases such as carbon dioxide and ethylene, which is beneficial to the long-term storage of fruits and vegetables.
An anesthetic (or anaesthetic) is a drug to prevent pain during surgery, completely blocking any feeling as opposed to an analgesic. A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesia, although others are used commonly by all disciplines. Anesthetics are categorized into two classes: general anesthetics, which cause a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body while maintaining consciousness. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. We produce anesthetic raw materials like tetrcacain, lidocaine prilocaine. These three anesthesia products are in commercial quantity.
