1. What is the oil yield rate of sunflower seeds?
1. The oil yield rate of sunflower seeds is generally between 30% and 50%, depending on factors such as the quality of the sunflower seeds, the planting environment, and the processing technology.
2. The oil yield of sunflower seeds is affected by factors such as the moisture, oil content and fatty acid composition of sunflower seeds. Generally speaking, good-quality sunflower seeds have low water content, high oil content, and balanced fatty acid composition, and their oil yield will increase accordingly.
3. Extended content: There are many ways to improve the oil yield of sunflower seeds, such as controlling the oil yield through seed selection, drying, shelling, crushing, cooking, and oil extraction of sunflower seeds. Among them, cooking is one of the commonly used methods to increase the oil yield. Cooking can rupture the oil cell wall of sunflower seeds, which is beneficial to the release and extraction of oil. The specific steps are: put the dried sunflower seeds into a cooking pot, heat them with steam, take them out after reaching a certain temperature and humidity, and then carry out crushing and oil extraction.
4. To sum up, the oil yield rate of sunflower seeds is between 30% and 50%, which is affected by various factors. In order to increase the oil yield of sunflower seeds, it can be controlled through seed selection, cooking, crushing and oil extraction.
