Small and medium-sized restaurants do not use pure sesame oil
The reporter came to Wanggang Farmers’ Comprehensive Market. In this market, the reporter found a business owner selling small ground sesame oil. The price offered by the business owner to the reporter was 10 yuan per catty. When the reporter asked for a lower price, the business owners said that the price was already the wholesale price. The reporter said that the market price in the urban area is cheaper than this wholesale market. The business owner revealed the secret to the reporter that the cheap sesame oil is made by mixing it. According to the industry owner, the products priced below 10 yuan per catty are made from salad oil, sesame oil, and black oil. According to the industry owner, pure sesame sesame oil only cost about 7 yuan in the past. Because sesame seeds are cheap and profitable, there are not many counterfeiters. Now that the price of sesame seeds has gone up, the price of oil has also gone up, and some small oil shops have started to make fake products. He said that there are still some large hotels that continue to use his pure sesame oil, while small and medium-sized hotels switch to the mixed sesame oil to reduce costs. So where can I buy essential oils? An insider said: "There are sellers of sesame oil essence on Chengde Street and Caoshi Street in Daowai District, and you can also buy it in chemical stores."
Sesame oil essence can be purchased easily
The reporter was Traces of sesame oil essence were found in several additive stores on Chengde Street in Daowai District.

According to the introduction of the merchants who sell small ground sesame oil in the grain and oil market, the small ground sesame oil purchased for 7 yuan per catty does not contain sesame at all. General salad oil is about 4 yuan per catty, sesame oil is about 40 yuan per bottle, and black oil is about 4 yuan per catty. The cost of the sesame oil is more than 4 yuan per catty.
