摘 要:皮蛋弹性是皮蛋品质的重要指标,研究坏皮蛋与好皮蛋由于弹性差异导致频率变化具有重要意义。本检测装置首先对皮蛋分拣结构进行设计,然后利用labview程序、INY9824加速度传感器、NI-USB-6251采集卡组成系统进行数据采集。应用本检测装置,通过实验数据分析得到皮蛋输出的第16个数据在-91至-94之间可判断为坏皮蛋,根据实验分析结果进行程序设计,完成皮蛋无损分选系统设计。

Abstract: Preserved egg elasticity is an important index of preserved egg quality. It is of great significance to study the frequency change caused by the difference of elasticity between bad preserved egg and good preserved egg. Firstly, the detection device designs structure of preserved egg sorting, then a system composed by LabVIEW program, INY9824 acceleration sensor and NI-USB-6251 acquisition card is used for data acquisition. Using the detection device, the 16th data of preserved egg output obtained through experimental data analysis, which can be judged as bad preserved egg between –91 and –94. According to the experimental analysis results, the program is designed to complete the design of preserved egg nondestructive sorting system.

皮蛋主要是利用其在堿性溶液中,蛋白质凝胶变成富有弹性固体的原理制成。皮蛋的传统加工工艺以及各种配方大同小异,大多采用纯碱、食盐、生石灰、茶叶、氧化铅等按照一定的比例混合均匀后,再将鸭蛋按照不同的加工方法进行处理,一定温度下一定时间后蛋白在碱液中逐渐变稠,凝固成富有弹性的固体后即为皮蛋[1]。
皮蛋在我国具有悠久的加工历史,但长期以来我国一直采用传统的生产方式和加工工艺,设备简陋,生产工艺无法控制,效率不高,质量不稳定[2]。近几年来国内外研究者采用多种形式对皮蛋好坏进行检测,如陈远哲等采用近红外光谱检测凝胶情况甄别皮蛋好坏[3],葛一凡等利用神经网络方法测定蛋壳的含铅值甄别皮蛋好坏[4],黄郁杰等采用络合滴定法与原子吸收光谱法测定皮蛋中的铅含量判断皮蛋好坏[5],但是利用皮蛋的弹性特点进行甄选的方式研究比较少。……
