咸蛋清脱盐及其在食品中的应用技术
咸蛋清 脱盐 蛋制品 废物综合利用
2008/7/20
所属年份：2000成果类型：应用技术所处阶段：成果体现形式：知识产权形式：项目合作方式：成果完成单位：浙江大学成果摘要：咸蛋是中华传统美食。从腌制成熟的咸鸭蛋中分离出的咸蛋黄作为其它食品加工的原料被广泛使用者，而剩下的咸蛋清因含盐量高达8-12%，难以利用而被废弃，不仅造成浪费，而且严重污染环境。仅上海朱家角蛋品厂98年生产咸黄800多万枚，其废弃物的咸蛋清就达270多吨，约合人民币160多万元。...
基于支持向量机的鸭蛋破损检测技术
鸭蛋 破损 检测 支持向量机
2008/3/23
基于传统统计学理论基础的鸭蛋破损检测方法有理论缺陷，因此提出了基于支持向量机的检测方法。试验结果验证该方法具有训练样本少、学习推广能力强等优点；基于径向基核函数(RBF)的SVM对鸭蛋破损检测的识别效果最佳，总体正确率达到97.5%。
为阐明酶解前热处理对鸡肉蛋白酶解性质的影响，采用差示扫描量热法分析鸡肉蛋白的热性质，研究热处理温度对鸡肉蛋白巯基(SH)、二硫键(S-S)含量以及碱性蛋白酶(Alcalase)、木瓜蛋白酶(Papain)酶解过程中氨基酸、肽释放的影响。结果表明：鸡肉蛋白有4个吸热峰，对应温度为63.7℃、67.6℃、74.3℃和 77.9℃；热处理温度增加，鸡肉蛋白中SH含量逐渐降低，而S-S含量逐渐增加，游离S...
