Many people think that only red jujubes count as ripe. Some vendors, in order to attract consumers, treat green jujubes to make them red. It is very simple: add saccharin to boiling water and just soak them for a while!” According to a person engaged in the fruit wholesale business, this kind of jujube is called “saccharin jujube.”
Normally ripened jujubes are green with red, and the side facing the sun is red. Farmers generally pick and bring them to market while the jujubes are still green, so if a jujube is completely red all over, there must be a problem. Ordinary jujubes only lose moisture after being stored, but “saccharin jujubes” that have been given a “beauty treatment” rot especially easily.
The state explicitly prohibits adding saccharin to fruit, but at present testing for food problems mainly consists of spot checks on vegetables and fruits in fixed locations such as markets and supermarkets. “Only those with a business license can pass third-party testing and serve as a basis for law enforcement. For mobile vendors, there is currently no way to use it as a basis for law enforcement.”
How do you select winter jujubes?
1. Look: normal jujubes have no obvious boundary between the green and red on the skin, while saccharin jujubes have a clear boundary between green and red on the skin;
2. Touch: normal jujubes have smooth and hard skin, while saccharin jujubes feel somewhat sticky on the outer skin and are softer than natural jujubes;
3. Taste: normal jujubes are sweet inside and out, while saccharin jujubes are mostly sweet on the skin of the jujube, and if tasted carefully there will be a bitter taste;
4. Store: normal jujubes are fine after being kept in a cool, dry place for a few days, while saccharin jujubes have their cells destroyed during soaking and rot extremely easily.
