The diferent drying method for moring leaves
Table 1 appearance changes of Moringa leaves during different drying processes
(the capacity is 1kg,moisture content is from 65% to 8%)

1.From this table we can see that different drying methods has a little effect for the color of the leaves.
2.But the microwave drying method is the shortest drying time and lowest energy consumption.
This is mainly because microwave can penetrate through the leaves, and the water can evaporate from the surface and internal of the leaves at the same time..
3.For freeze drying ,the temperature is ten degrees in the drying process,so also can maintain the color of the leaves.
But time is longest and energy consumption is largest. Not very practical in the industrial production.

1.The effects of different drying methods on metal elements content is not big.
2.But for VC, VE, VA.The microwave drying and infrared drying, for the destruction of the two is the least of them.
3.For the protein and fat,the microwave is the most suitable method.Because now high protein,
low fat products are most popular.
4.But time of the infrared drying is longer than microwave drying.
And consumption is larger than microwave drying method too.
5.So from these experiments and analysis,
we can see the microwave drying machine is the most suitable method for moringa.
