| Abstract: |
| During the storage period of soybean, when the external environment changes, the stability of soybean oil body is easy to change, which leads to the phenomenon of soybean oil migration, resulting in the decrease of soybean oil yield and economic loss. In order to provide theoretical reference for the scientific storage of soybean and the further processing and utilization of soybean oil body, the composition and structure of soybean oil body, the factors affecting the stability of soybean oil body, the methods for improving the stability of soybean oil body, the influence of oil migration on soybean quality and the prevention and control measures of soybean oil migration were reviewed. Soybean oil bodies are suborganelles for storing lipid, and they are mainly composed of phospholipids, alkaline proteins embedded in phospholipids and triacylglycerol surrounded by a half-unit membrane composed of phospholipids-proteins. Soybean species, temperature, pH and extraction method all affect the stability of soybean oil body. The stability of soybean oil body can be improved by controlling temperature, adding polyphenols and polysaccharides.In addition, oil migration will deepen the color of soybean and reduce the nutrition of soybean and quality of processed products. Soybean oil migration can be prevented and controlled by timely harvesting of soybean, reducing mechanical damage during soybean transportation, reducing soybean moisture, controlling soybean storage temperature and adopting air conditioning technology. In the future, the mechanism of soybean oil migration can be explored from the perspective of changes in the structure of soybean oil body. |
