Description

一种红薯枣的制备方法
技术领域
本发明属于食品加工技术领域,具体涉及一种红薯枣的制备方法。
背景技术
红薯在我国各个地方都有种植,红薯的成分里面含有大量的膳食纤维,有些人在生活中会存在便秘的现象,而吃蒸的红薯就能有效的刺激肠道,促进肠道的蠕动,对身体的排毒有很好的功效,红薯的成分里面含有一种抑制皮肤的黑色素的成分,这种成分还能防止肌肤的松弛和老化,吃红薯可以让皮肤更加的有弹性,可以有效的抑制皮肤的衰老;另外,红薯中含有氨基酸素,可以补充人体所需的氨基酸素,红薯中还含有糖蛋白,而糖蛋白这种成分是可以增强身体的免疫力,对身体的机能有很好的保护作用,吃红薯会使身体的免疫力越来越好;红薯中还含有大量的维生素、钾元素等,这些都是可以预防心血管疾病发生的,维生素是可以帮助身体抗氧化,叶酸是可以帮助我们降低血液的氨基酸水平,从而达到保护心血管的作用。但是新鲜的红薯不好保存,容易长芽,所以,人们就将红薯加工成各种产品,以方便食用,而红薯枣以其味道甜美深受人们的喜爱,但是目前的红薯枣在制备过程中添加剂较多,特别是糖和防腐剂,不利于人们的身体健康,而且制备出的红薯枣色泽不好、营养损失严重。所以,急需对现有工艺进行改进,以满足人们的需求。
发明内容
为解决上述问题,本发明的目的是提供一种红薯枣的制备方法。
一种红薯枣的制备方法,包括以下步骤:
(1)红薯储存:将刚采挖的红薯置于阴凉通风处,晾干表面水分,然后在地上铺一层稻壳和草木灰的混合物,再铺一层红薯,再铺一层稻壳和草木灰的混合物,如此往复交替铺设3-10层,然后用稻壳和草木灰的混合物覆盖10-20cm,储存25-100天,储存温度为8-12℃;
(2)备料:将红薯洗净、并沥干水分,然后削皮,去除皮纤维、病点和黑点;
(3)第一次蒸煮:将步骤(2)中的红薯放入密闭蒸锅内蒸煮,蒸至不硬心、刚刚熟透即可;
(4)第一次晾晒:将第一次蒸煮过的红薯完全冷却之后,纵向切成红薯条,红薯条的尺寸为1.5-2.5cm╳2-5cm╳5-10cm,然后晒干至表面不粘手,水分含量为65 wt%-75 wt%;
(5)第二次蒸煮:将第一次晾晒好的红薯枣再次放入密闭蒸锅内蒸煮,锅内的压力为0.02-0.04Mpa,时间为50-90min;
(6)第二次晾晒:将步骤(5)中蒸煮好的红薯枣晾晒,直至水分含量为55 wt%-65 wt%;
(7)第三次蒸煮:将步骤(6)中的红薯枣流水冲洗除尘,然后放入普通蒸锅内蒸煮,蒸煮时间为30-60min;
(8)烘干:将步骤(7)中蒸煮好的红薯枣置于真空干燥箱内烘干,直至水分含量为35wt%-45 wt%;
(9)包装:将步骤(8)中晾晒好的红薯枣进行杀菌、送检,然后装袋。
本发明红薯枣的制备方法,与现有技术相比,其有益效果在于:本发明制备方法简单,通过三次蒸煮、两次晾晒和一次烘干,使得制备出的红薯枣口感劲道、Q弹、香味浓郁、零添加,未加入糖,但是制备出的红薯枣糖度也很高,且色泽金黄,本发明制备方法使得红薯的营养成分损失少。
