1. Microwave sterilization of meat products, such as spiced trotters, cooked food with animal viscera, ham, western-style sausages, all kinds of braised pork, chickens and ducks, etc. , placed on the counter of the deli produced by the deli manufacturer; Its shelf life is very short, generally it will rot within three days at the longest. If it is preserved by microwave sterilization, its freshness, tenderness and flavor remain unchanged, and the preservation period can reach more than 2 months. Widely used in the drying, sterilization and preservation of beef jerky, dried pork, fish fillets and other meat products.
2. Microwave sterilization and fresh-keeping of vegetables Wild vegetables are often called green foods and are welcomed by users at home and abroad. However, its shelf life is greatly affected. For example, mustard grown in Jiangsu and Anhui is a tribute dish with a long history and is sold as a semi-finished product. Later, traditional pasteurization methods, such as high temperature and high pressure, can achieve certain sterilization effect, but the brittleness of cabbage is weakened, which seriously affects the product quality, limits the expansion of production and is not conducive to export. After using microwave sterilization technology, the sterilization temperature is only about 80 degrees, which completely achieves the commercial aseptic effect, and the storage period can be as long as 9 months. Taste indicators such as flavor and crispness meet the sales demand.
Microwave is an electromagnetic wave with extremely high frequency, and its frequency range is 300MHZ-300GMHZ. Microwave technology is a radio technology that rose in the middle of last century. It was first widely used in radio communication, broadcasting, television, navigation, remote control, telemetry, radar and other fields. In recent years, as an energy source, it has been widely used in economic construction and people's daily life. For example, household microwave ovens have already entered thousands of households. As an industrial processing method, it was first applied to the food industry, mainly used for drying, sterilization, baking, ripening, puffing, thawing by temperature adjustment, and fermentation ripening, which promoted the development of the food industry. With the development of economy and science and technology, microwave energy technology will be more widely used in food industry.
