Is it true that only one bottle of oil is produced on an acre of land?

It is true that only one bottle of oil is produced on an acre of land. According to public information, only one bottle of oil is produced in an acre of rice field. Rice oil is extracted from rice husk embryo, accounting for only 5% of rice, but containing 64% of rice nutritional essence. Because of this, rice husk rice embryo has always been regarded by experts as "a natural nutrient source that has not been effectively developed". In addition, the technical requirements of rice oil are complex and the refining is difficult. We should know that the oil yield of fresh rice skin and rice embryo is only 16%, and only 60% of refined oil can be produced after refining, and only about 5L bottles of rice oil can be produced in one acre of rice field.
