Sesame oil has become a widely popular edible oil due to its rich nutrients and natural flavor. However, how to ensure the quality and nutritional content of sesame oil during the extraction process is an issue that needs to be explored in depth. This article will start from the problem and provide a series of solutions to ensure that every drop of sesame oil meets food-grade safety and nutritional standards. ## Problem 1: Poor quality of impurities ### explain First of all, material selection is a crucial step in the entire sesame oil extraction process. The quality of the raw materials directly affects the quality of the final product. However, many manufacturers tend to ignore this step, resulting in the presence of impurities, which affects the purity and aroma of the final product. Solution **Quality testing and screening**: Choose reputable raw material suppliers and conduct strict quality testing. Use efficient screening equipment to remove impurities and low-quality sesame seeds. **Step 1: Washing**: The raw materials should be washed several times with running water to ensure that there are no impurities. This step is crucial to ensure the purity of the final product. ## Problem 2: Loss of nutrients ### explain In the traditional hot pressing process, many nutrients in sesame will be destroyed or lost due to high temperature heating, which not only reduces the nutritional value of sesame oil, but also affects its natural flavor and shelf life. Solution **Modernized cold pressing technology**: Different from traditional hot pressing, the cold pressing technology is carried out at a lower temperature throughout the process, thereby maximizing the retention of sesame nutrients and natural aroma. **Step 2: Drying**: Before cold pressing, low-temperature drying should be performed to remove excess moisture, thereby avoiding the temperature increase caused by water vaporization during the oil pressing process. ## Question 3: Residual impurities ### explain Even if the temperature is kept low during the oil extraction process, there may still be some tiny impurities, such as fine sesame residues and other debris, which will affect the purity and taste of the sesame oil. Solution **Multiple filtration**: At the final stage of the extraction process, it should pass through multiple filtration devices to remove all possible impurities. **Step 3: Filtration**: Use high-efficiency filtration equipment for multiple filtrations to ensure the purity of the final product. Quality control is an important step in ensuring that every drop of oil meets food-grade safety and nutritional standards. ## Infographic Example: Sesame Oil Extraction Process 1. **Choose high quality sesame seeds** * Conduct quality inspection and screening 2. **Washing and drying** * Wash with running water for multiple times and dry at low temperature 3. **Cold Pressing Technology Extraction** * Retain nutrients and natural flavor 4. **Multiple Filters** * Remove impurities to ensure purity Through the above refined process, every drop of sesame oil not only achieves the best taste, but also meets the health needs of consumers in terms of nutritional content. In general, every step of sesame oil extraction is critical, and negligence in any step may affect the quality of the final product. Through strict quality control and modern cold pressing technology, we can ensure the high quality and nutritional content of sesame oil, providing consumers with a healthy and safe choice. ### Marketing Talk Choose us and enjoy truly pure and high-quality sesame oil.
