In this paper, the four economic traits of camellia oleifera seeds, including grain weight, shelling percentage, water content and oil content were investigated. On this basis, aqueous extraction process of camellia seed oil was carried out with the oil extraction rate as indicators. The results showed that the optimum extraction procedure of aqueous extraction was: camellia seed paste was mixed fivefold water(v∶m), then roasted at 190 ℃ for 20 min, at last incubated in constant water bath for 120 min. The oil indicators extracted under th...
