外观分辨真伪
1.在购买巧克力产品时，看清产品包装。首先是产品名称，有些厂家设计外包装时“巧克力”字体大且颜色醒目，而“代可可脂”字体小，从而迷惑消费者。其次是产品配料表。配料表未标示可可脂，而标示代可可脂，就不能称为巧克力。
2.纯正的、高品质的巧克力，产品的外观精制、图案完整;掰开后，可以看到产品的质地、品质很好的巧克力是非常细腻和均匀、入口即溶;质地差的巧克力大大小小气孔多，分布不匀，表平面光泽暗淡，入口难溶。
3.高档手工制作，巧克力不含代可可脂，可可脂不低于35%，从欧洲进口品牌原料。
品尝分真伪
1.纯天然可可脂巧克力的融点在30°左右，而氢化植物油的融点在22°左右。所以，带可可脂巧克力在口中比真巧克力融化的更快。真正的巧克力，在口中融化的感觉像雪一样慢慢的融化;而带可可脂巧克力其主要成分是氢化植物油，在口中融化非常迅速，所谓“入口即化”。
2.真巧克力的香是纯天然的可可香。假巧克力不含可可脂，其香味来自人造香精。当你把这两种产品分别放在密封的食品袋里，对比闻其香味，就能很明显的对比出两者完全的不同。真巧克力的可可香，是一种带有淡淡苦味的很低沉的香，这种香味持续而浓烈，而带可可脂巧克力的香，是一种飘忽的，带有糖果香 。
3.真巧克力用鲜奶油调制，保质期短。假巧克力用氢化油调制的，保质期长。真巧克力制作中的中调馅用鲜奶油等天然食材，讲究新鲜，打开以后，如果不及时食用，尤其在干燥的空气中暴露时间3到天，巧克力的口感就会大打折扣，并迅速变干，如果长期处在温暖潮湿的环境里还会生霉。而代可可脂巧克力，不管在空气中放多久都不会变干且保持油润感，因为是用氢化油调制的，和超市里的巧克力一样，稳定性很好，估计一年都不会变质，保质期很长。
4.真巧克力在口里是慢慢融化，融化的过程给人愉快的感觉，没有油腻感，融完后嘴里残留可可的香。代可可脂巧克力在口中融化很快，融化时有油腻感，融化完后嘴里没有可可香的残留。如果能够同时交叉的吃这两种巧克力，吃的中间用清水漱口，就能更加明显的感觉到两者的不同。
