Domestic microwave energy food processing
   Country due to diet cooking habits consistent with the psychological and economic affordability constraints, household cooking microwave applications have just begun, family ownership rate is not high . Similarly, in industrial microwave heating equipment and the application is still in research and development stage , but it has also been successfully applied examples. According to statistics, only in food processing has been used for 25 cases . By domestic microwave energy in food processing application examples , you can clearly see the features of microwave heating in the following areas of food processing can be full of possibilities.
    1 microwave penetrating strong , uniform temperature make the material list , so the number of slow drying with conventional heating , particularly for non-volatile matter of logic internal moisture food drying , baking and more reflected Traits . Such as , for dried pasta , fried donuts , pastries and preserves products, and products such as drying , can improve the efficiency and food quality .
    (2) can better maintain food quality and flavor
    For example, by microwave drying konjac flour, white color method , without curing bleaching treatment . Another example is the microwave drying of betel nut taro maintains its unique flavor and nutrients. This is the conventional method of heating and drying the root difficult to achieve the quality standards. Domestic product of some soil drying process of the dry products with Bai Jie color, often smoked sulfur implementation process , resulting in excessive sulfur content of products . It is reported that domestic ginger dried products because it contains excessive levels of sulfur was rejected European market imports . It contains high amount of sulfur reason lies in the manufacturing process of the product has taken over a white Chak Luu I hid white craft due. If you do not change with the use of microwave drying characteristics of the material color can make products in the process eradicating sulfur pollution.
   3 in the microwave heating process, in addition to thermal effects , the material is also accompanied by biological effects ( non-thermal effects ) , it can kill within a shorter time to ask endanger human health, E. coli, spores and other micro-organisms and dense shade, eggs . Without the use of food preservatives premise, to achieve food hygiene standards or extend food shelf life.
    Food needs to be heated baking , drying and sterilization , anti-virus process , use the microwave method can be combined to two processes , improve efficiency, save sterilization or heating system equipment investment , improve the working environment .
    4 . Microwave energy can reach deep into heat the material , the material will allow the formation of deep water quickly evaporates high internal steam pressure conditions , forcing the material extruded . Appropriate far OBJECTS puffing drying effect will likely eliminate tough material surface wrinkled skin atrophy common situation , maintaining the appearance of tough material shape before drying . For example, in starch , protein raw materials such as raw materials are not mixed with less convenience food by blowing , but also can be made Peng of dried food products. The shape of the microwave process proceeds to avoid fried puffed dried products processes get less oil or oil products puffing - this is a very popular , very popular convenience food varieties.
    5 microwave heating frozen food or ingredient quickly warmed to thaw, thawing materials to keep nutrients and freshness . Is the reach of conventional methods thaw . It is particularly suitable for food processing plants must be in the shortest possible time , large quantities of food processing solution as the main raw material of ice frozen meat, fish fillets and other treatment processes .
    Apparently due to industrial microwave heating equipment currently one-time investment is large, technically demanding, and good enough to bear for electricity or psychological limitations , making the domestic industrial microwave heating applications also depends on progress - equipment and technology to carry out further research , reduce costs and strong universal application of microwave energy knowledge , but with the microwave heating effect gradually highlighting strengths and awareness , adoption, prospects are bright.
