In theory, the pressing oil is safer because it uses the traditional pressing process and does not contain any chemical additives. The leaching oil is subjected to multiple processes such as deodorization, which contains chemical additives. At present, the state stipulates that the quality of the pressing oil and the leaching oil is qualified. Can eat.
Freshly pressed oil is a traditional physical pressing process. It extracts pure earthworm oil and earthen tea oil from the countryside. 100% only takes the first press oil, retains the original flavor of the oil, and does not contain any chemical additives.
