How to choose rock sugar

Rock sugar is a very good condiment. Many people like to eat it. However, some friends are confused when buying rock sugar, that is, how to choose rock sugar. When choosing rock sugar, they are worried about buying some poor quality and bad taste. Moreover, some small vendors nowadays will wrap unqualified rock sugar in a lot of outer packaging in order to sell it. What should they do when choosing rock sugar? Let me briefly introduce it below.

The National Food Safety Law allows rock sugar and white sugar to contain a small amount of sulfur dioxide, but has clear regulations on the proportion of sulfur dioxide, which cannot exceed 4 mg/kg. However, after visiting, the reporter found that the outer packaging of most rock sugar products on the market only lists the proportions of various nutrients, but there is no clear indication of whether it contains sulfur dioxide and what proportion it contains.

"Nowadays, many sugar factories cannot do without sulfur dioxide from production to packaging. In the production process, in addition to the bleaching effect, it can also filter out some heavy metal impurities. In the packaging process, sulfur dioxide can play a certain preservative role." Except for some exported sugars that have clear regulations on ingredients, most rock sugar and white sugar on the market contain sulfur dioxide. Moreover, according to the standards issued by the state, there are a large number of products that exceed the standards, and supervision is not in place.

So, how should citizens choose safe rock sugar? There are basically three types of rock sugar on the market: one is relatively white in color, not too transparent, and in grains; one is very white and very transparent, which should be the best looking in terms of appearance; the last one is a large block of rock sugar with a slightly yellowish tint, which is also called local rock sugar, and its production process is relatively traditional.

The first type has a low sulfur dioxide content and is edible; the second type has a sulfur dioxide content that obviously exceeds the standard and will be harmful to the human body after consumption; he suggested that citizens choose the third type of rock sugar, which is the safest, because although this large piece of slightly yellowish rock sugar does not look good, it uses traditional craftsmanship and generally does not add sulfur dioxide.

When we usually choose rock sugar, we must identify it according to the above methods. There are many kinds of rock sugar sold on the market. If you choose unqualified rock sugar, after you buy it home, the taste will be different, and many physical problems will occur. Therefore, when choosing rock sugar, you must pay attention to the above requirements to buy good rock sugar.
