摘要
以籼米为主要原料,辅以虫草培养基,通过双螺杆挤压技术制备富含虫草素的籼米复合米。选取虫草培养基添加量、水分、套筒温度、螺杆转速四个技术参数为主要因素,研究制备糊化度较低的富含虫草素的籼米复合米(简称虫草复合米)的最佳工艺参数。结果表明,虫草培养基添加量35%、水分40%、套筒温度100℃、螺杆转速250r/min时,虫草复合米的品质指标较好,其蛋白质、脂肪以及虫草素含量明显高于原籼米。
With indica rice as the main raw material, supplemented with cordyceps culture, complex indica rice rich in cordycepin was prepared by a twin-screw. Selecting the cordyceps culture medium content, moisture content, barrel tempera- ture and screw speed as the main factor, the complex cordycepin indica rice （ called cordycepin indica meters ） with low degree of pasting were obtained . The optimal parameters were as.. cordyceps culture media content 35 ~, moisture content 40 ~~0, bar tel temperature 100~C and screw speed 250 r/min. Under the conditions,the quality of restructuring indica rice with cordycepin was good, and the test data of protein, fat and cordycepin content were significantly higher than that of the indica rice .
