Description
技术领域
本发明涉及食品加工技术领域，具体为一种营养紫薯条的制作方法。
背景技术
紫薯是一种很神奇的物种，颜色十分的漂亮，而且营养成分很丰富，紫薯外形小巧可爱，已经成为越来越受欢迎的食物，除了具有普通红薯的营养成分之外，紫薯还富含硒元素和花青素以及丰富的蛋白质，氨基酸及维生素C、B、A等多种维生素以及磷、铁等10多种天然矿物质元素。
现有薯条、薯片的制造方法有不足之处：一是速冻使薯片内含糖降低、并且糖的分布更加不均，所制薯片不仅口感欠佳，而且缺乏营养价值；二是此工艺为油炸工艺，被世界卫生组裂为垃圾食品；紫薯的淀粉含量高，如采用微波制片，其淀粉在微波的作用下，不仅不会产生脆香干，而且会使薯片内的淀粉形成发筋，既不利于食用，也不利于身体健康；由于微波靠食物本身的分子热运动加热，无法形成烘烤薯片的色香。因此，需要一种营养健康美味的紫薯条制作方法
发明内容
为解决以上现有问题，本发明提供一种营养紫薯条的制作方法。本发明通过以下技术方案实现：
一种营养紫薯条的制作方法，所述方法包括如下步骤：
1)选择无黑斑、无霉变、无冻伤、无虫蛀的成熟新鲜富硒紫薯为原料，洗去表面泥土，放入含有0.04-0.06％柠檬醋中浸制1-1.5h，脱水沥干；
2)将沥干后的紫薯削皮，去除皮纤维和苦丝；
3)将去皮后的紫薯放入至盐水常温浸泡10-15min小时杀菌去涩味，再用清水常温浸泡，时间为3h；
4)将上述浸泡后的紫薯捞出切成规格的条块状；
5)a、将紫薯条放入加了新鲜菊花、陈皮和蜂蜜的水中煮制10-15min，捞出后放凉沥干，然后置于烘干房内烘3-5h，即可得到酥脆的紫薯条；
b、将紫薯条放入调制的鸡蛋蜂蜜液中裹上一层蜜汁，然后放入烤箱中烘烤至熟既可得软糯的紫薯条。
进一步的，所述步骤5)a中新鲜菊花、陈皮、蜂蜜与水的重量比是3：3：5：1。
进一步的，所述步骤5)b鸡蛋与蜂蜜的比例为1:2。
进一步的，所述步骤5)a中的烘干房内真空度为20-50pa，温度为45-60℃。
进一步的，所述步骤5)a中新鲜菊花用含有1-2％白醋的凉水浸泡10-20min，洗净后摊放在阴凉通风处8-10h。
进一步的，所述步骤4)中的切割规格为长度8-10cm，厚度及宽度均为1.5-2cm。
本发明的有益效果：本发明采用的紫薯条制作方法不仅保持了紫薯原有的营养成分，同时又富有自然的花香，可使紫薯的口味多样化，提升食用口感，且营养丰富，从而增加消费者对紫薯的喜爱程度，进一步提高紫薯的经济价值；本发明工艺步骤简单，最大限度地保留了紫薯的营养成分，能够保持紫薯原味，所得的紫薯干保质期长、口感好，长期食用有益人体健康；本发明制作的紫薯条营养丰富，口味独特，不含有对人体健康和生长有害的物质，且原料来源广泛，制备工艺简单，成本低廉，富含多种人体必需的微量元素，可以满足不同消费者的饮食需求。
