How to identify the authenticity of yam powder? How can you tell if it s yam powder?

1. Look at the color of the vermicelli.

When we choose vermicelli, first look at its color, most people like to buy crystal clear kind of vermicelli, that is, it looks particularly transparent, if the vermicelli looks particularly transparent, it is very likely that a ingredient called gelatin is added to it, such vermicelli is actually unhealthy, if it is a real vermicelli, he will not be a very transparent color, and there are some small particles on the surface of the vermicelli, although such vermicelli will not look good, but often there will be real vermicelli, So don't just choose the pretty ones when choosing vermicelli.

2. Fold the vermicelli.

When you buy vermicelli, you can gently fold it by hand, but some bosses may not let you fold, then you will quietly fold it while he doesn't see it, if it breaks off, then this is generally real vermicelli, if the vermicelli is folded no matter how it is folded, it means that there are more additives doped in it, many merchants are to have a good appearance to add some impurities, these are not good for the body, so that the vermicelli is constantly folded as much as possible.

3. Burn it with fire.

Of course, the person who sells vermicelli in this method will not necessarily let you do it, but if he is sure that he is selling real vermicelli, he is not afraid that you will do such an experiment, of course, it is best to do such an operation with the permission of others, otherwise it is very likely that some disputes will occur, just a small little vermicelli, use a lighter to burn it gently, the vermicelli will look like it will swell, then there is no problem with this vermicelli, if it is the opposite situation, then there is a problem.

Here's how to tell the difference:

Yam is a dish that we often eat in our daily life, the yam we used to see is relatively stout, and there is more water, in recent years, there has been an iron stick yam, because it looks like an iron rod and is slender and long, so it is called an iron stick yam, in fact, these two kinds of yam are different in addition to the appearance, in fact, the difference is still very big.

1. Look at the shape of the yam.

The most intuitive way to distinguish between ordinary yam and iron stick yam is to look at the appearance, because as mentioned above, the iron stick yam is called the iron stick yam because it is thin and long, and the shape is very similar to the iron rod. Our common yams are relatively thick, and some yams are not very straight in shape, and they will have irregular shapes or even round.

The appearance characteristics of iron stick yam are slender, long and straight. In fact, through these points, it is possible to distinguish the two kinds of yams most intuitively, but it is not guaranteed that some merchants will take out relatively small and immature ordinary yams to sell them as iron stick yams, so they also need to combine the following points to completely distinguish them.

2. Look at the skin of the yam.

When we choose yams, we can look at the skin of yams, which can also intuitively distinguish these two kinds of yams. We all know that yams have roots on the outside, but the roots on the outer skin of ordinary yams are relatively rare, and the "pores" on the surface are relatively rare, and the overall skin looks relatively smooth.

The roots on the iron stick yam are not only many but also very long, and there are more "pores", and there are many small bumps and spots on the outer skin, and the outer skin is relatively rough, which can also be intuitively distinguished between the two kinds of yams.

3. Look at the section of the yam.

Nowadays, many yams on the market are relatively long, and they will basically be broken into several pieces in the process of transportation, and we can naturally see the section of the yam directly when selling.

Let's take a closer look at the section of the yam, such as the mucus on it, and the effect of drawing, such a yam is generally an iron stick yam, and the texture of the iron stick yam is relatively more delicate, firm, and not easy to break.

If we see that the section of this yam has no drawing effect, although there is mucus but it is relatively rare, and then look at the texture of the section, we can see that the umami of the yam is looser, and the moisture content is relatively higher, such a yam is an ordinary yam, and it will be broken with a light break.

1. How to distinguish the real and fake Huai Yam All kinds of yams in the market claim to be Huai Yam, and most of the goods in Shandong and Hebei are counterfeited. The easiest way to distinguish is to burn the yam on the stove, burn the hair, cook it, eat it with the skin, and the mouth is numb.

2. Whether it is Wenxian County, Henan Province, is it Huai Yam. Driven by profits, some merchants enter Shandong and Hebei yams at low prices, and then pretend to be Huai yams.

3. How to distinguish between a soil yam and a sandy yam. It is also very simple, the soil is very hard, and it is difficult for yams to be produced freely in it, so the yam produced is mostly curved, and the surface is difficult to flatten.

In sandy soil, yams are easy to grow freely, so the yam produced is mostly straight and has a smooth surface. Moreover, due to the limitation of soil, Wenxian County is an alluvial plain of the Yellow River, and there is very little land, mostly sandy land. The yield of yam is very small.

Preservation of fresh yam: Fresh yam is easy to oxidize with the oxygen in the air, and brown will also form when in contact with iron or metal, so it is best to use a bamboo knife or plastic sheet to cut the yam, first draw a line on the skin, and then peel it into sections by hand.

The incision is easy to oxidize, you can soak it in rice wine first, and then dry it with a hair dryer to promote wound healing, and then wrap it in a napkin, wrap a few layers of newspaper around it, and put it in a cool corner. The yam should be soaked in salt water immediately after slicing to prevent oxidation and blackening.

Precautions: Bulk iron stick yam storage conditions: It can be stored for a long time under dry and ventilated conditions, remember not to let it germinate, the sprouted yam will produce trace amounts of toxins, do not eat.

This product is the dried rhizome of the dioscaceae plant. 11 Dig in December, cut off the roots, wash the soil, scrape off the skin with a bamboo knife, and dry it in the sun or dried, that is, the hairy yam. Choose a coarse hairy yam, soak it in water, add a slight heat, and cover it with a quilt to keep it moist and stuffy, then put it on a wooden board and knead it into a cylindrical shape, cut the two ends together, dry and light, that is, the light yam.

One look at the "heart line". There is no heart line in the middle of the yam slices, whereas there is a heart line in the middle of the tapioca chips, and although the heart line is small, it can be seen if you look closely. Some cassava chips are thinly shaved, and after drying, the heart thread tends to fall out, but if the heart thread falls off, it will leave a small hole.

If there is a small hole in the middle, it must be cassava chips. Look at the edges. The skin of the yam is very thin and is peeled clean before slicing.

Whereas, tapioca skin is much thicker than yam skin. Some thumb-sized cassava are too small to peel and often don't take the time to peel them, so after slicing into thousands of slices, thick skins remain on the edges. Whoever has thick skin will be a false yam.

Second-hand touch to distinguish the real from the fake. Dried yam slices contain a lot of starch, and when you touch it with your hands, it feels more delicate, and there will be more starch sticking to your hands. Although cassava also contains a lot of starch, it has more crude fiber than yams, and it feels coarser to the touch than yams, and there is less starch left on the hands.

Yam powder is generally to buy yam powder or watch the seller to powder the whole process, otherwise it is very easy to adulterate, generally the method found on the Internet to distinguish whether it is yam powder is mainly to see whether the yam powder is pure white and delicate, after dipping a little in the mouth, when it is just imported, it is only sweet and has no other taste, and it will be sour later.
