The invention discloses camellia oil and a processing process thereof. The processing process comprises the following steps: a, firstly, performing camellia seed collection and storage treatment on araw material; b, after the step a is completed, pretreating the raw material; c, after the step b is completed, treating with a cold pressing machine; d, after the step c is completed, performing oil-residue separation through plate frame filtration; e, after the step d is completed, performing secondary extraction on oil cakes; f, after the step e is completed, processing pressed crude camellia oil through alkali refining. On the basis of cold pressing, food additives are added, so that the stability, the anti-oxidation effect and the thermal stability of oil can be improved; secondly, a leaching method is implemented, since oil cells are not completely damaged in a pretreatment process, and albuminous degeneration is not very thoroughly achieved, barrel pressure is not very large, and the oil residue rate of pressed cakes is relatively high, an effect of extracting oil from oil cakes twice can be achieved together with the leaching method, the oil residue rate is reduced, the oil extraction effect is improved, and convenience can be brought to popularization and application.
