How to increase the oil yield of peanut oil
Peanut oil is a common edible oil with rich nutritional value and unique taste. During the processing of peanut oil, the oil yield directly affects the yield and quality of peanut oil.
What are the other methods to improve the oil yield of peanut oil?
Adopt advanced pressing technology and equipment
Adopting advanced pressing technology and equipment can significantly improve the oil yield and quality of peanut oil. For example, the use of high-efficiency oil presses or low-temperature pressing techniques can maximize peanut oil extraction while avoiding oxidation and nutrient loss caused by high temperatures. In addition, the use of precision filtration equipment can remove impurities and off-flavors, improving the quality and stability of peanut oil.
Application of Enzymatic Technology
Enzymatic technology is a method that utilizes the action of enzymes to break down components such as plant cell walls and proteins. In the extraction process of peanut oil, the combined use of enzymatic technology can further promote the release and extraction of oil. Enzymatic technology can destroy the cell walls and proteins of peanut cells, reduce the viscosity and cohesion of the oil, and improve the oil yield and oil quality.
First, the role of enzymatic technology mechanism
- Decomposition of the cell wall: the enzyme can specifically act on the cell wall of peanut cells, decompose it into small molecules, making it easier to release the oil from the cell.
- Degradation of proteins: proteins in peanuts can be degraded under the action of enzymes, thus reducing the cohesion and viscosity of oil, which is conducive to the extraction and separation of oil.
Second, the application of enzymatic technology in peanut oil extraction
- Improve the oil yield: Enzymatic technology can significantly improve the oil yield of peanut oil. By destroying the cell wall and degrading the protein, more oil can be released, thus improving the extraction efficiency.
- Improvement of oil quality: Enzymatic technology can not only increase the oil yield, but also improve the quality of oil. The enzyme digestion reduces the impurities in the oil, so the extracted peanut oil is purer and tastes better.
- Combined with traditional pressing method: In practice, enzymatic technology is usually used in combination with traditional pressing method. Enzymatic technology is first used to destroy cell walls and degrade proteins, and then the oil is extruded by pressing. This method can give full play to the advantages of enzyme digestion technology and pressing method, and further improve the oil yield and oil quality.
Optimization and improvement of enzyme digestion technology
- Selection of suitable enzyme: Different enzymes have different catalytic properties and scope of action. Therefore, when selecting enzymes, it is necessary to match the demand of peanut oil extraction and the catalytic properties of enzymes in order to obtain the best extraction effect.
- Optimization of reaction conditions: The effect of enzymatic reaction is affected by many factors, such as temperature, pH value, reaction time, etc.. By optimizing these reaction conditions, the enzymatic efficiency and oil yield can be further improved.
- Strengthen the quality control: It is necessary to strengthen the quality control in the enzyme digestion process to ensure the stability and reliability of each step of the process. At the same time, it is also necessary to carry out strict testing and inspection of the extracted peanut oil to ensure that its quality and safety meet the requirements of the relevant standards.
Advantages and Challenges of Enzymatic Technology
- Advantage: Enzymatic technology has the advantages of high efficiency, environmental protection and mildness. It can significantly increase the oil yield and improve the quality of fats and oils, and at the same time reduce the pollution of the environment and the waste of resources.
- Challenges: Despite the many advantages of enzymatic technology in peanut oil extraction, there are still some challenges. For example, the cost of enzymes is high, and the stability and reusability of enzymes need to be improved. In addition, there are differences in the adaptability of different varieties of peanuts to the enzymatic technology, which need to be optimized and adapted to specific situations.
Application of supercritical extraction technology
Supercritical extraction technology is a method that utilizes the special properties of supercritical fluid to extract the active ingredients of plants. Supercritical fluid has good permeability and solubility, which can quickly dissolve the oil and other components in plant cells. In the extraction process of peanut oil, the application of supercritical fluid extraction technology can efficiently extract the oil and grease, and at the same time, it can avoid the use of high temperature and chemical solvents, and improve the quality and safety of the oil and grease. Research shows that the use of supercritical fluid extraction technology can improve the oil yield of peanut oil, and has better selectivity and low temperature adaptability.
Optimization of processing technology
Optimizing the processing technology can further improve the oil yield and quality of peanut oil. For example, in the traditional pressing method, multi-stage pressing and repeated pressing methods can be used to improve the oil yield; in the solvent leaching method, multi-stage leaching and counter-current leaching methods can be used to improve the extraction efficiency and quality of oil. In addition, optimizing the processing process can also reduce the loss and pollution during processing and improve the yield and quality of the products.
Strengthen the quality control in the production process
Strengthening the quality control in the production process is one of the key steps to improve the oil yield and quality of peanut oil. By strengthening the quality control in the production process, we can ensure the stability and reliability of each step of the process, so as to improve the overall quality of the product. For example, in the planting process, it is necessary to choose excellent varieties and scientific planting methods; in the harvesting process, it is necessary to choose the appropriate time and method; in the processing process, it is necessary to strictly control the process parameters and operating procedures. In addition, it is also necessary to strengthen the testing and inspection of products to ensure that the quality and safety of products meet the requirements of the relevant standards.
