Abstract
本发明提供了一种纯天然红枣即食营养脆片的制备方法,包括以下步骤:选取主料和提香辅料制备、食药辅料制备;用除尘机对食品级粉碎机进行3‑5min清理,将食品级粉碎机内部清理干净;将制备的主料、提香辅料和食药辅料按重量计量混合后置入食品级粉碎机内,粉碎得到460目的纯天然红枣即食营养干粉,含水量为2%;放入脆片模具中,螺杆挤压、干粉压片制成卡通形状,或辊压制成直径为30‑40mm,厚度为1.5‑2mm的圆片形状;制得的产品经过微波膨化后,用密闭遮光的铝箔复合袋真空充氮包装,本发明能最大限度地保留原料的营养成分,营养物质的流失及损耗少,并能更好的发挥其药效,更易于被人体肠胃直接吸收,方便携带及服用,制作工艺简单、时间短,操作方便,节能降耗。
Description
技术领域
本发明主要涉及红枣加工的技术领域,具体为一种纯天然红枣即食营养脆片的制备方法。
背景技术
众所周知红枣的保健功效很强,其丰富的蛋白质、脂肪、糖类、有机酸、胡萝卜素、维生素、部分矿物质钙、磷、铁等,有“鲜维生素丸”的绰号,是一种重要滋补物,深受广大消费者的喜爱。常见的食用方法以全枣、枣片、枣粉、枣浆等,但由于季节性强的原因,人们不能一年四季都食用到新鲜红枣,这也使得红枣的深加工产品市场需求开始呈现旺盛态势。
近年来,随着生活节奏的加快,方便类纯天然食品越来越受到消费者的喜爱。目前,消费者购买方便类纯天然食品除了考虑方便之外,其卫生、营养、口感也是考虑的重要因素,因此营养保健纯天然食品也正随着人们的需求变化而不断发展。在红枣的加工过程中,红枣中多种营养成分的分解和红枣褐变(焦化)程度跟加工温度和加工时间紧密相关,加工时间越长温度越高红枣中多种营养成分的损失和红枣褐变(焦化)越严重。红枣加工工艺技术的快慢和温度高低密切相关,要把红枣加工成所需产品,需要较长时间和较高温度,这样就加剧了红枣中各类营养成分的丢失和红枣的褐变(焦化)程度。
现有公开的各类果蔬复合脆片及其制作方法,都是先用蒸锅常压蒸煮至熟透后制备果蔬浓缩浆,再采用微波真空冷冻干燥或其他加热方式干燥和真空低温油炸相结合的工艺制作果蔬脆片等等;这些方法存在着如下的缺点:1)制得浓缩浆不宜长期保存,且加热温度高、工艺时间过长,营养和各种维生素损耗过大。2)原料细化的颗粒较大,食用品质和口感较差,人体肠胃直接吸收不好。3)繁杂的制作工艺多,添加各类名目繁多辅料和添加剂,不利健康。4)投资大,能耗高,产品含有残留油脂,焦味重,能量高,营养成分少,含糖量高,辅助功能少等。
发明内容
本发明主要提供了一种纯天然红枣即食营养脆片的制备方法,用以解决上述背景技术中提出的技术问题。
本发明解决上述技术问题采用的技术方案为:
一种纯天然红枣即食营养脆片的制备方法,其特征在于,包括以下步骤:
S1,选取熟度合适的主料和提香辅料制备,选取地域合适的食药辅料制备;
S2,用27Kpa的食品级除尘机,对食品级粉碎机进行3-5min清理,将食品级粉碎机内部滞留的纯天然红枣即食营养干粉清理干净,;
S3,将制备的主料、提香辅料和食药辅料按重量计量混合后置入食品级粉碎机内,粉碎得到460目的纯天然红枣即食营养干粉,含水量为2%;
S4,放入脆片模具中,通过螺杆挤压、干粉压片制成卡通形状,或辊压制成直径为30-40mm,厚度为1.5-2mm的圆片形状;
S5,步骤S4制得的产品经过微波膨化后,用密闭遮光的铝箔复合袋真空充氮包装。
