| 摘要: |
| 脱脂蛹粉中蛋白质量分数近80%,脂肪仅3%,是良好的食品资源,但具有不良的腥味.以醋酸与蚕蛹腥味成份形成易挥发物质,通过水蒸汽蒸馏可除去腥味.其最适工艺条件为:样品200 g时,用醋酸2 ml,反应温度80 ℃,加热时间20 min,蒸馏时间20min.经最适条件下脱腥的脱脂蛹粉不影响食用感官评品. |

| Study on Technology of Removing Odour From Degreased Pupa Powder by Distillation |
|
|
| Abstract: |
| Degreased pupa powder contains protein of about 80% and fat of 3%,and is a good food source,but has some odour. Volatile materials were formed by adding acetic acid and then could be removed along with the odour. The optimum conditons were:sample of 200 g,acetic acid of 2 ml,temperature of 80℃,heating time of 20 min and distillation time of 20 min. |
| Key words: degreased pupa powder removed odour acetic acid distillation |
