Description
技术领域
本发明主要涉及食品加工技术领域,尤其涉及一种即食南瓜干的制备方法。
背景技术
南瓜,是我国的常见蔬菜之一,营养丰富,富含淀粉、纤维素、蛋白质、胡萝卜素、维生素和矿质元素,能够增强免疫力,促进胃肠功能,消炎止痛,解毒杀虫,降血糖,降血压,美容护肤,保护视力,促进骨骼发育,防癌治癌;但是目前市场上大多都是销售新鲜南瓜,南瓜的即食深加工产品极少,不能满足消费者的需求。
发明内容
为了弥补已有技术的缺陷,本发明的目的是提供一种即食南瓜干的制备方法。
一种即食南瓜干的制备方法,包括以下步骤:
(1)原料准备:将老南瓜洗净,去皮和瓤,切片,厚度为3~4mm,置于食盐水中浸泡30~40分钟,得南瓜片;
(2)一次烘干:将南瓜片置于烘箱中,于54~56℃烘干至含水量减少20~25%,向南瓜片表面喷洒大豆低聚糖溶液,再置于47~49℃烘干至含水量继续减少15~20%,增加南瓜片的强度,避免后期处理时发生软烂,得一次烘干南瓜片;
(3)一次发酵:向一次烘干南瓜片中接入乳酸菌,于35~37℃发酵3~4天,产生丰富的小分子营养成分,增加南瓜片的鲜味和强度,促进胃肠功能,得一次发酵南瓜片;
(4)二次发酵:向一次发酵南瓜片中加入调味料A,于37~39℃继续发酵12~16小时,丰富南瓜片风味,增加消费者食欲,得二次发酵南瓜片;
(5)二次烘干:将二次发酵南瓜片置于烘箱中,于46~48℃烘干至含水量为18~20%,减少南瓜片水分,使口感更加劲道香甜,得二次烘干南瓜片;
(6)调味:将二次烘干南瓜片置于蒸汽中蒸制13~15分钟,软化南瓜片组织,取出,置于调味料B中腌制4~6小时,不影响南瓜片的天然色泽,使南瓜片香味浓郁,取出,得调味南瓜片;
(7)干燥:将调味南瓜片置于冷冻干燥机中,冷冻干燥至含水量为17~19%,快速减少南瓜片的水分,保留南瓜片的营养和风味,口感更加松软筋道,得即食南瓜干。
所述步骤(2)的大豆低聚糖溶液,质量浓度为14~16%,喷洒量为南瓜片重量的8~10%。
所述步骤(3)的乳酸菌,经二次活化后离心,取沉淀,加入量为南瓜片重量的4~6%,由以下重量份的菌株组成:干酪乳杆菌31~33、嗜酸乳杆菌27~29、嗜热链球菌26~28、德氏乳杆菌21~23、开菲尔15~17。
所述步骤(4)的调味料A,加入量为南瓜片重量的1.4~1.6%,由以下重量份的原料组成:辣椒12~14、胡椒10~12、花椒10~12、八角8~10、孜然6~8、草果5~7、肉桂5~7,将所有原料混合后粉碎至60~80目,得调味料A。
所述步骤(6)的调味料B,由以下重量份的原料组成:大骨汤80~100、米粉22~24、香葱13~15、生姜10~12、料酒6~8、鸡精3~5、植物油14~16,将植物油加热至105~110℃,加入香葱和生姜,炒香,加入剩下的原料,熬制粘稠,加入适量食盐,搅拌均匀,得调味料B。
所述的大骨汤的制备方法为,将牛筒骨洗净,漂烫,加入牛筒骨重量60~70倍量的水和香辛料,加热煮沸后熬煮至体积为原来的1/20,过滤除渣,得大骨汤。
所述的植物油,由以下重量份的原料制成:花生油25~27、玉米油21~23、棕榈油16~18、芝麻油2~4。
所述步骤(7)的冷冻干燥,温度为-39~-37℃。
所述即食南瓜干的制备方法得到的即食南瓜干。
本发明的优点是:本发明提供的即食南瓜干的制备方法,方法简单,得到的南瓜干色泽金黄,香味浓郁,松软筋道,增加市场上南瓜的深加工产品,不含任何添加剂,安全健康,满足消费者的营养和口感需求;老南瓜洗净切片后进行一次烘干,减少部分水分后喷洒大豆低聚糖溶液,再继续烘干,增加南瓜片的强度,避免后期处理时发生软烂;一次烘干后接入乳酸菌进行一次发酵,产生丰富的小分子营养成分,增加南瓜片的鲜味和强度,促进胃肠功能;加入调味料A后继续进行短时的二次发酵,丰富南瓜片风味,增加消费者食欲;二次发酵后进行低温二次烘干,减少南瓜片水分,使口感更加劲道香甜;二次发酵后先对南瓜片进行蒸制,软化南瓜片组织,再置于调味料B中进行腌制,促进调味料B渗入南瓜片,调味料B加入牛筒骨熬制的大骨汤,鲜香浓郁,加入的米粉粘附在南瓜片表面,不影响南瓜片的天然色泽,使南瓜片香味浓郁;调味后将南瓜片进行冷冻干燥,快速减少南瓜片的水分,保留南瓜片的营养和风味,口感更加松软筋道。
具体实施方式
下面用具体实施例说明本发明。
