What is the difference between fake nori and real nori
In society, in order to covet the small interests of untrustworthy people more and more, what fake clothes, fake herbs, fake food and so on appeared very often, algae collectively, red algae, red algae, red cabbage, algae body is membrane-shaped, known as the foliar body, purple or brownish-green, the shape of the species vary, nori is a marine red algae, the foliar body by embedded in a thin layer of A layer of cells in the gelatinous composition, dark brown, red or purple, purslane fixer disc-shaped, pseudo-root filamentous, growing in the shallow sea intertidal zone on the rocks, a variety of species, mainly striped purslane, altar purslane, Gan purslane, etc., China's coastal areas have been artificially cultivated, the beginning of the 21st century China's purslane production jumped to the first place in the world, rich in protein and phosphorus, calcium, etc., the following we take a look at the real purslane and fake purslane what is the The difference between real and fake purslane.

How to identify real and fake nori? First of all, we can observe through the color of purple cabbage. It contains phycocyanin, so the color of the purple cabbage we usually buy should be dark brown or purple-brown, with a natural luster.
Nowadays, some black-hearted manufacturers will use cheap seaweed or sea vegetables dyed with color to sell as purple cabbage in order to save cost. The second method is to put a small piece of purple cabbage in the water to soak for a period of time. The color of the water in which the real seaweed is soaked is basically unchanged. If the color of the water becomes bright purple red or even the color of ink, it is definitely fake.
Another method is to take a small piece of seaweed with fire grilled, grilled good quality seaweed should be green, like seaweed color. If the roast becomes yellow, it is poor quality purple cabbage; the last method is to identify by taste. Some counterfeit nori is surprisingly made of plastic film. There is no problem with the color of the bubble water, but put in the mouth to chew, how to chew not rotten, with a hand a bit is also very elastic.
