to prove the situation of Ms. Nie, the reporter came to investigate the black sesame related stalls in the big world market. There are a variety of grains and grains on the booth, and no black sesame seeds are placed. "Do you have black sesame?" asked the reporter. At this time, a middle-aged man took out two packs of black sesame under the counter. "One is 8 yuan a Jin, one is 10 yuan a Jin." The man said.
8 yuan a jin of black sesame, the color looks black, always yellowing, and sesame seeds are not full, and no luster.

reporters went to another miscellaneous grain store in the market to pick black sesame seeds. Shopkeeper said: "authentic black sesame will not fade, and will not be dark black."

expert: natural black sesame for dark gray
black sesame after immersion normal? Is the black sesame sold by Ms. NIE is dyed?
later, the reporter consulted the relevant experts of the Municipal Academy of Agricultural Sciences. Experts say that natural black sesame seeds are dark grey in general and are not shiny black. Water soaked in black sesame will not filter out "ink". Black sesame will only slightly "fade" and the color of water is pale grey. However, when the old black sesame is soaked in water for a period of time, the color of the water will become purple or black, but this color is a natural pigment, and it will not appear to be seriously washed many times.
it is worth the public's attention that the public should be careful to buy the abnormal black sesame. It is best to put in the palm of the hand with a little water beforehand and gently rub the black sesame in the palm of his hand, and the color left by the hand is more careful. Wash and soak in water for a while before eating. If the black sesame seeds are brownish red or black, they can generally be judged to be dyed sesame seeds.
Insider: the misfortune of black sesame
reporter found in an interview that the price of black sesame and white sesame is different, why the white sesame is dyed black sales?
"black sesame is better than white sesame." He Jun, a citizen who has been selling grains for many years, said. He told reporters that most people think that the nutritional value of black sesame is higher than white sesame, black sesame has the effect of making black hair black, blood enriching and defecating, often eating black sesame, which can keep skin tender, delicate and smooth. The sale of black sesame is obviously better than that of white sesame. "One day selling hundreds of pounds of black sesame seeds, but white sesame seeds only have a few catties." He Jun said.
industry insiders say that some illegal traders will dye white sesame into black sesame sales, which is mainly to make the white sesame with a slightly lower price and a slightly worse quality to be dyed, and to impersonate the black sesame to raise the price. In addition, the black sesame, which is "dressed", looks black and bright, sells well, and sells far better than undyed black sesame.
