I am from Nankang, Ganzhou, and almost every family in the countryside has it. Don't worry, here's the thing. It's just some pomace left over from oil extraction. Don't use the following if you want to dislike it. We won't be stingy with a little oil, because it's for the baby and we can give it to you. For example, when the seed oil blooms outside in winter, it will precipitate below if it is too cold, and disappear when it is slightly heated. It's quite cold there.
