Dehulling refers to the process of removing the outer hull or shell from seeds. This process is typically done for oilseeds like sunflower and soybean to improve the quality and yield of the oil extracted.
- Sunflower: Sunflower seeds are dehulled to extract the oil efficiently. However, dehulling is often done in combination with other seeds.
- Sunflower and soybean: Correct! Both sunflower and soybean are commonly dehulled during oil extraction to improve the yield and quality of the oil.
- Soybean and groundnut: While soybean is dehulled, groundnut (peanut) is generally not subjected to dehulling in the same way.
- Soybean: Soybeans are often dehulled during oil extraction, but dehulling alone is not exclusive to soybean seeds.
Thus, the correct answer is (2) Sunflower and soybean.
