The scent of sesame oil and fragrant peanut oil must be obtained through hot pressing. The raw materials of the cold press must be selected, otherwise the cold press will be affected by the different maturity of the raw materials and the harmful substances contained in the raw materials, for example, it will have a serious impact on the quality of cold pressed oil when aflatoxin in moldy oil and gossypol toxin in cottonseed.
