Become an expert in identification
As the saying goes, "When people reach middle age, they have to soak wolfberries in a thermos cup", not to mention that I am a new old man who has just retired, and I will not take it off at home - wolfberry, red dates, longan, walnuts and so on, so when I heard that wolfberry is poisonous, I am naturally a little nervous and panicked, and I am afraid that the wolfberry at home is also among the poisonous wolfberry, so I quickly incarnated as an identification expert to detect and determine whether the wolfberry I bought is poisonous wolfberry? Here's how I did it
The detection is carried out in three steps:
Step 1 – Look at the place of origin:
First of all, let's see if the wolfberry at home is produced in Qingyuan County, Shaanxi, fortunately, it is not from this hard-hit area, and the wolfberry at home comes from Ningxia;
Step 2: Look at the manufacturer's instructions:
The manufacturer wrote in black and white in the store - no sulfur and no dyeing, and you must remember that you bought it for the manufacturer's promise and statement. It is not news that wolfberry and many Chinese medicinal materials are smoked with sulfur, it has always existed before, but it still cannot be eradicated, and I don't know what governments and supervision departments at all levels have done for so many years? It's all tears when you think about it [tears]
Step 3 - Water Immersion Detection:
The third step is also the most critical step, because there are many cases of manufacturers and merchants swearing on the surface and hurting consumers by unscrupulous means behind the scenes. Therefore, you must test in person to rest assured;
Grab a little wolfberry at home and put it into a goblet wine glass, then pour some water, after a few minutes to see if the color of the water has become red and yellow, if it turns red and yellow, it means that the wolfberry has not been smoked by sulfur, because the internal tissue of the wolfberry smoked by sulfur will be destroyed, so that the pigment of the wolfberry will not penetrate into the water, the water will not change color, if there is no discoloration or clear water, it means that the wolfberry has been smoked by sulfur, it is poisonous and resolutely cannot be eaten;
A few minutes later, the answer was revealed - the wolfberries at home have not been smoked with sulfur, which is safe and reliable, and now I am finally relieved again;
Now you can also use this method to test whether the wolfberries in your home are poisonous wolfberries!
