Many people like to eat yam, but they don't choose it. They don't know which kind of yam is delicious. There are some yams in the market, including long, short, thick and thin. So how should our friends choose? Some people think thick yam is good, while others think thin yam is good. However, this is not the case. Today, I will share with you some tips for choosing yam. When buying yam, we only need to remember these four points, regardless of thickness, to ensure that it is very delicious. Choosing a good yam is very practical.
How to buy yam?
1. Look at the skin
In the vegetable market or supermarket, there are mainly iron yam and common yam. No matter which kind, you should carefully look at the appearance of yam. Good quality yam, skin intact, earthy brown, no moth-eaten, no mildew spots. This yam is of better quality. If its appearance is damaged, the nutrition in yam will be quickly lost. Yam with black spots on the epidermis is not recommended because it may have been infected with the disease. When buying, we try to buy yam with intact skin and no obvious spots on it.
2. Look at these fibrous roots
Because yam grows underground, there are some fibrous roots in the skin of yam. These fibrous roots are used by yam to absorb nutrients. To buy yam, you should choose yam with dense fibrous roots on the surface. The more fibrous roots of the same variety, the more nutrients absorbed and the higher the nutritional value. On the contrary, if we find that the fibrous roots of yam are very small, or the nutritional value is not so high, or the yam is not fresh, and the fibrous roots fall off because of long storage time, there is no need to buy such yam.
3. Look at the cross section.
Some yam in the market has broken parts, so we can see the cross section of yam. Fresh yam should be snow-white, clean and sticky. If we see that the cross section is yellow or rusty, it means that this yam is not fresh, so try not to buy it.
Step 4 weigh yourself
Finally, we should weigh the yam by hand and choose two yams that look similar in length and thickness for comparison. Generally speaking, the heavier yam has the best quality, because it is richer in water content and nutrients, so it tastes good and is worth buying. On the contrary, the yam with light taste is either undernourished or left for too long, resulting in water loss. This kind of yam is generally not recommended for everyone to buy.
Finally, when many people peel or slice yam, there will be something sticky on it. There will be some plant alkaloids in these mucus, which may cause itchy skin on both hands. In addition to wearing gloves to handle yam, you can also apply a layer of vinegar to your hands, so that touching yam will not itch.
