Microwave extraction of natural aromatic plants
    Spices as food industry, cosmetics and pharmaceutical industries important raw materials , spices tech industrial development is inseparable from the application of microwave radiation (MW1) technology was first used in the military , and later gradually entered the human society in various fields , especially in spices industry has received widespread attention. below the microwave technology application in the fragrance industry research , especially aromatic plants and spices microwave extraction technology compounds microwave synthesis technology to make a brief introduction.
    A microwave extraction of natural aromatic plants
    Microwave extraction (MicrowaveE xtration) ME technology began in the Hungarian scholar GanzIer.K. Reported his 1986 T microwave can accelerate the extraction of some organic ingredients in food , which is an organic analytical sample pretreatment opened up a new road. Soon , GanzIer.K turn microwave extraction technology used to extract natural products in plant cells , and was a great success.
    1.1 The principle of microwave extraction technology
    Microwave -induced extraction method is the recent development of fragrances extracted from plants of new technologies. It utilizes a very short wavelength , high frequency radiation to heat the plant leaves , leaf tissue internal water is a polar molecule , can absorb the microwave energy through a medium , and generate heat. Since a sudden increase in the internal temperature of the plant material , and maintaining this temperature until the internal pressure exceeds the capacity expansion of the cell wall , cell rupture , glandular cells essential oils contained in the system flow freely from the cell walls , passing the extraction medium transferred to the surrounding . The choice the medium has a strong capacity through the microwave with respect to the plant material is still at a low temperature , so that fragrance materials are easily captured and dissolve the extraction medium . foreign patent describes the use of a microwave -induced extraction peppermint oil , apiole , cedar oil , garlic oil instance , while no one country be discussed. According to the data reported , the microwave has excellent penetrating power , can be applied to any natural products , such as the genus Anemone , sharp leaves Mulan , algae , lichens, and animal tissues, such as liver , kidney , egg yolk , and then extract useful substances.
