| 中文摘要: |
| 以香花油茶籽为原料，开展油茶籽压榨工艺的改进研究，考察了不同含壳率、香花油茶籽含水率、炒仁温度、炒仁时间、蒸粉时间和包饼厚度对香花油茶籽油品质的影响。确定改进后的最佳工艺条件为：含壳率10%，香花油茶籽含水率10.3%，炒仁温度150 ℃，炒仁时间45 min，蒸粉温度100 ℃，蒸粉时间15 min，包饼厚度6 cm。在最佳工艺条件下，得到的香花油茶籽油的水分及挥发物的含量0.06%，不溶性杂质含量0.04%，酸价（KOH）0.85 mg/g，过氧化值0.17 g/100 g，维生素E、角鲨烯、总黄酮和茶多酚的含量分别为20.92、21.08、2.12、71.27 mg/100 g，均优于传统压榨香花油茶籽油的理化指标，符合GB/T 11765—2018一级油茶籽油标准。 |

| The research on the improvement of pressing process of oil-tea camellia seed oil was carried out with Camellia osmantha seed as raw material.The influences of rate of bull in kernel, moisture content of Camellia osmantha seed, roasting temperature, roasting time, steaming time and thickness of cooked flake on the quality of Camellia osmantha seed oil were studied.The optimal process conditions were determined as follows: rate of hull in kernel 10%, moisture content of Camellia osmantha seed 103%, roasting temperature 150 ℃,roasting time 45 min,steaming temperature 100 ℃, steaming time 15 min and thickness of cooked flake 6 cm. Under the optimal conditions, the various indexes of Camellia osmantha seed oil were obtained as follows: content of moisture and volatiles 0.06%，insoluble impurity content 004%, acid value 0.85 mgKOH/g,peroxide value 0.17 g/100 g, contents of vitamin E, squalene, total flavonoids and tea polyphenols 20.92, 21.08, 2.12 mg/100 g and 71.27 mg/100 g, respectively,which were all prior to those of oil prepared by traditional press method.The physicochemical indexes of Camellia osmantha seed oil obtained by the improved method met the requirement of first grade oil-tea camellia seed oil in GB/T 11765—2018. |
