| 摘 要： | 以兔皮为原料，研究稀盐酸短时诱导兔皮制备明胶的工艺。以明胶提取率和凝胶强度为评价指标，对兔皮明胶制备工艺中的盐酸质量分数、盐酸处理时间、提胶pH值、提胶温度4 个因素进行了优化，在此基础上通过正交试验确定最佳工艺为盐酸质量分数1%、盐酸处理时间10 min、提胶温度65 ℃、提胶pH 4。在此工艺条件下明胶提取率高达（86.85±1.71）%，凝胶强度为（481.43±16.89）g。明胶基本性质符合GB 6783-2013《食品添加剂：明胶》要求。 |

| Abstract: | The extraction induced by short-term treatment with dilute hydrochloric acid of gelatin from rabbit skin was investigated in the current work. Optimization of 4 process parameters including HCl concentration, HCl treatment time, extraction pH and temperature for improved extraction yield and gel strength of gelatin was implemented using an orthogonal array design. The optimum extraction conditions were determined as follows: 10 min treatment with 1% HCl and subsequent extraction in water acidified to pH 4 at 65 ℃. Under these conditions, the yield and gel strength of gelatin were (86.85 ± 1.71)% and (481.43 ± 16.89) g, respectively. The basic properties of rabbit skin gelatin met the requirements of the Chinese national standard (GB 6783—2013). |
