The first step to get sweet potato vermicelli is to look at its appearance and observe its color. Pure true sweet potato powder is different in color because of the differences in the quality of sweet potato starch and the fineness of processing. For example, some sweet potato powders are dark in color, some are light in color, and some are even transparent, showing these colors, which are normal. On the contrary, it is the sweet potato powder that is transparent and bright in color and too beautiful to be noticed. This kind of sweet potato powder is generally added with additives or mixed with true and false.

after reading the color, look at the thickness of sweet potato powder. Generally speaking, sweet potato powder is also divided into thickness. For the same batch of sweet potato powder, if the thickness of sweet potato powder is different, it is generally handmade; If it's the same thickness, it's usually made by machines and may be adulterated fans. This point should not be taken as the main basis, but only as a reference, because there is no guarantee that the machine will produce fake vermicelli. )

Second smell:

Smell the taste

The main raw material of authentic sweet potato powder is sweet potato starch, which has no taste, so the sweet potato powder made from it naturally has no taste. But when you smell the unpleasant smell on the sweet potato powder, or the smell of ink and other odors, this is usually fake sweet potato powder. In addition, you can burn the sweet potato powder with a lighter. After the sweet potato powder is burned, if it smells burnt, this is the real sweet potato powder; If it continues to burn after burning, and it will also release black smoke and unpleasant smell, this kind is fake vermicelli, and this kind must not be bought. If you buy it, don't eat it any more.

three breaks: breaking the vermicelli

The toughness of sweet potato vermicelli made of sweet potato starch is relatively poor. When you break it by hand, it will usually break, so we usually see some broken vermicelli fall into the packaging bag. If you break it by hand, the sweet potato powder is elastic and not easy to break, which is basically "fake sweet potato powder".

Is it hard to tell whether sweet potato vermicelli is true or false?

remember "seeing, smelling and breaking" and easily distinguish the true from the false! We must learn these distinguishing methods, so that we can buy the genuine conscience and not add burden to our bodies.
