1. Quality preservation technology for camellia oil raw materials and products: The storage effects of camellia oleifera seeds, camellia oleifera cake and crude camellia oil under different conditions were investigated, and the optimal storage methods were proposed. By combining the analysis of camellia oil fatty acids with geographic longitude and latitude, the geographic distribution regions of fatty acids were delineated, and the camellia oil producing areas with high-quality fatty acid composition were identified.
2. New technologies for camellia oil processing: The key processes and technical parameters of low-temperature pressing, supercritical CO2 extraction and aqueous enzymatic extraction for camellia oleifera seeds were studied. The vitamin E content in camellia oil obtained by low-temperature pressing was 38.22% higher than that of conventional pressed oil. The color value of camellia oil extracted by supercritical CO2 extraction reached the national standard for first-grade pressed oil, and its contents of vitamin E, β-carotene and squalene were 9.23%, 28.43% and 27.48% higher than those of conventional screw-pressed oil, respectively. The contents of vitamin E and β-carotene in camellia oil extracted by aqueous enzymatic extraction were also significantly higher than those of conventional pressing method. Up to now, 2 authorized national invention patents have been granted for these new camellia oil processing technologies.
3. R&D of high-quality camellia oil products: A novel environmentally friendly decolorizing material was developed. By optimizing the main technical parameters in the refining process, a demonstration base for premium camellia oil processing was established, which helped multiple enterprises solve the bottleneck problems in camellia oil production. Organic camellia oil raw material bases and processing demonstration bases were built, and both organic camellia oleifera forests and organic camellia oil have passed the national organic certification. Based on the study of fatty acid compositions of different camellia oleifera species, camellia oil raw materials with oil content over 60% and high oleic acid content were screened out. Their oil content and oleic acid content were 15.07% and 6.15% higher than those of common camellia oleifera, respectively. Light-colored and original-flavor camellia oil products were developed. We helped 2 enterprises establish R&D centers and cultivated 3 technology-based enterprises.
4. By-product R&D: The product development of camellia oleifera by-products including tea saponin and natural tea meal was carried out. A series of products such as "Tea Clean" and "Cleaning Treasure" were developed, which improved the added value of camellia oleifera.
5. Promotion and application: Through technological innovation and achievement transformation, the technologies have been widely promoted and applied in Zhejiang Province and other main camellia oleifera producing areas in China:
(1) An organic camellia oil production base covering 15,600 mu was established in Jiande City, Zhejiang Province, including 5,000 mu of core base and 10,600 mu of "enterprise + farmer" model base, with an annual output of more than 200 tons of organic camellia oil.
(2) Two demonstration bases for premium camellia oil processing were supported and established by Zhejiang Changshan Shenshan Camellia Oil Development Co., Ltd. and Jiande Xiawu Agricultural Development Center, with an annual output of more than 200 tons of premium camellia oil.
(3) Two demonstration bases for premium oil processing were supported and established by Camellia Oleifera Processing Plant in Shijian Township, Jinyun County and Jiangshan Chazhiyu Camellia Oil Development Co., Ltd., with an annual production capacity of 1,000 tons.
(4) Organic production technology promotion and demonstration bases were established in Zhejiang Changshan Changfa Grain and Oil Co., Ltd. and Qingtian Tenghe Camellia Oil Co., Ltd.
(5) Light-colored and original-flavor camellia oil production bases were established in Jinyun Xiandu Camellia Oil Co., Ltd. and Qingtian Tenghe Camellia Oil Co., Ltd.
(6) A camellia oleifera by-product processing demonstration base was supported and established by Jiangshan Chazhiyu Technology Development Co., Ltd.
(7) A total of 20 relevant technical training sessions were held, training more than 300 technical personnel and forest farmers.
