The invention discloses a processing technology of camellia oil. The processing technology comprises the steps: (1) sorting, removing impurities, and drying; (2) crushing to obtain camellia seed kernels, and stoving the camellia seed kernels; (3) cooling the camellia seed kernels, adding fresh cavings or camellia seeds, and carrying out low-temperature squeezing; (4) heating, adding citric acid, adding water, mixing, standing, and removing the water and the impurities; (5) adding active carbon or diatomite under the vacuum condition, and filtering; and (6) mixing, cooling, standing to grow grains, and filtering. With the adoption of the processing technology, as the camellia seeds with the oil content of 28-30 percent are adopted as the raw materials, the camellia oil prepared by virtue of the scientific and reasonable process is a non-transgenic product, the inherent flavor, fragrance and nutrient substances of the camellia oil are kept to the maximum, the oil yielding rate and the squeezing efficiency are high, the deodorization and decoloration efficiency are good, the green processing requirements are conformed, and the food safety is guaranteed.
