What factors affect palm oil yield?_Palm Oil Extraction FAQ
What factors affect palm oil yield? Firstly, the oil content rate of your FFB will affect the palm oil yield. The higher oil content rate your FFB has, the more oil you will get after palm oil mill. The oil content rate is different in different regions and countries, so it is better for you to check the oil content rate of your local FFB first.
