一看表面特征，正品的阿胶表面为黑褐色，胶块很平整、色泽均匀，没有油孔、气孔。而假阿胶胶块的表面通常是棕黄或青黄色，有的有油孔、气孔等，胶块也不太规则。

二是看质地，正品的阿胶质地硬而脆，将胶块放在桌面或硬物上轻轻一拍，就会拍碎，成无数块小块，而假冒阿胶则不容易拍碎。

三是闻气味，正品的阿胶闻起来有一股淡淡的香味，而假冒的阿胶则有刺鼻的异味，或者腥臭味。

如何选购：
第一招 认品牌让假冒伪劣产品无处藏身
首先要学会看外包装，正宗东阿阿胶的外包装及标识是经过专业设计、注册认证。东阿阿胶包装右边印刷文字有凹凸感、标识、图案纹路清晰。
包装表面胶块色泽均匀、表面光滑，并印有“东阿阿胶”产品标识由吉祥云和东阿阿胶四个字组成，要认准 标志，且注册商标标志的位置在吉祥云图案 的右上角。
第二招 看产品
正宗阿胶具有黄透如琥珀色，或光黑如莹漆者为真，真者不作皮臭，夏日亦不湿软等特点，这些可以从胶块本身进行鉴别：
东阿阿胶：呈规则长方形，表面棕褐色，光亮，胶块正面印字“东阿阿胶”端正清晰，颜色均匀，无气孔及油孔，气味清香，质硬而脆，一拍即碎。
第三招 打电话
凡真正东阿阿胶，包装上都有防伪标识，这点是辨清“真李逵、假李鬼”的不二砝码。买到阿胶，只要刮开包装盒上的防伪标签涂层，拨打电话均为免费电话。按语音提示输入全部防伪码，按“#”结束，便可马上知道真伪，建议消费者在购买时仔细核对。

“中药三大宝，人参鹿茸和阿胶”。阿胶因出自山东东阿县而得名，既是名贵中药，又是滋补保健价值甚广、男女老少皆宜的保健品。随着人民群众生活水平的提高和保健意识的增强，阿胶更是越来越受到人们的青睐。也正是因为如此，一些利欲熏心的不法者打起了仿冒名牌产品的主意，甚至制售假劣阿胶牟取暴利，严重侵害了消费者的合法权益甚至生命安全。“3.15”来临之际，记者特别采访了有关业内专家，请专家就如何选购阿胶等问题予以了解答。 近年来有关部门查处的涉及阿胶假冒案件显示，假冒伪劣阿胶有的是用制革厂的下角料、废旧塑料等制成，里面含有大量有毒有害物质；有些假冒阿胶产品由于杂质提炼不干净，人们食用后无法吸收，因而产生肠梗阻不得不到医院里开刀取出；也有的假阿胶是用马皮制作的，与阿胶的效果正好相反，不是补血而是下血。为此专家特别提醒消费者，购买阿胶绝不能贪图价钱便宜，看到阿胶就买，一定要到正规的医院和药店去买正品名牌产品，同时，掌握必要的真伪阿胶识别方法也是十分必要的。 一是看包装。正品阿胶的外包装印刷清晰、精美，品名、标记有凹凸感，外贴有防伪标志。伪品阿胶外包装印刷较粗糙，字体笔画纹路模糊、粗糙，无防伪标志，常有错字、漏字现象，且常有生产批号编制错误等。 二是查产品。首先要看胶块的性状。正品阿胶呈规则的长方形，胶块大小、厚薄均一，块形方正、平整，胶块表面平整光亮、色泽均匀，呈棕褐色，“色如琥珀，黑如茔漆”。伪品一般乌黑，胶块不规则有臭味等异味，表面粗糙无光泽，胶块大小、薄厚不一，块重差异大，有油气孔。其次要看胶块上的品名。正品阿胶胶块正面印字用医用氧化铁红印制，字迹端正清晰，呈暗红色，而伪品一般用漆等物印制，字迹模糊、字体歪斜，没有压痕，容易掉色或抹去。其三看透光性。正品阿胶对光透视，呈半透明琥珀色或棕色，伪品对光透视色泽较暗或不透光。其四看质地。正品阿胶质硬而脆，若用手掰，不弯曲，稍用力即断。如果将胶块在手中用力拍在硬物上，裂成数块，断面光亮，无油孔、气孔及明显刀纹。伪品阿胶质硬而不脆，可弯曲，不易折断，拍打不易碎，断面灰黑色，不光亮，容易发软黏合。 三是闻气味。对着胶块轻轻一哈，正品阿胶有清香味，伪品有臭味。正品阿胶砸碎后放入杯中，加沸水适量立即盖上杯盖，放置1～2分钟，轻轻打开，胶液澄清，无肉眼可见颗粒状异物，嗅闻有轻微豆油和阿胶香味，味甘咸，气清香，无任何异臭味。伪品不易溶化，有的出现不溶化的絮状物，溶化后胶液浑浊，常有肉眼可见颗粒状异物，水溶液有刺鼻的腥臭味等。
阿胶真品有光泽，有香气，断面可透明。假的阿胶往往是黑色，不透明，无光泽，也没有特有的香气的。建议在正规药店购买阿胶
药店的东阿阿胶都是真的，认准OTC标志，加东阿阿胶标志就行了。而且铁盒后面都是有防伪码的
