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.

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.

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.
