Description
技术领域
本发明涉及食品加工技术领域,具体涉及一种无花干果的制备方法。
背景技术
无花果是一种开花植物,隶属于桑科榕属,主要生长于一些热带和温带的地方,属亚热带落叶小乔木。无花果目前已知有八百个品种,绝大部分都是常绿品种,只有长于温带地方的才是落叶品种,无花果具有健胃清肠,消肿解毒的作用,主要用于治肠炎,痢疾,便秘,痔疮,喉痛,痈疮疥癣,利咽喉,开胃驱虫。
由于无花果成熟期短、难保存,是一种季节性水果,导致无花果集中上市,若不能被市场消费掉,会造成资源的浪费,目前,无花果大多被当作水果被直接食用,而将无花果制作成干制品,是较为新颖的技术方法,可以将无花果的营养物质在任何时间进行保留食用。
发明内容
本发明所要解决的技术问题在于提供一种口味鲜美,保证无花果中营养物质不流失,口感醇正的无花干果的制备方法
本发明所要解决的技术问题采用以下技术方案来实现:
一种无花干果的制备方法,其特征在于,步骤如下:
1)市场收购新鲜的无花果,无花果保证落果时间保证48小时之内,并且选用同一品种的无花果,且收购采摘后的无花果必须保证根蒂平顺;
2)将上述无花果进行初步清洗,然后放入冷库中,预冷1-2h,冷库内的温度控制在3-5℃,二氧化碳浓度控制为13-15%、湿度控制在60-68%;
3)将步骤1中预冷后的无花果取出后,取淡盐水对无花果进行一次淋洗,然后在采用清水再次冲洗附着在无花果表面的淡盐水,淡盐水的浓度在4-7%为宜;
4)将上述清洗后的无花果取出,然后将其自然晾干或者冷风吹干,然后采用保鲜剂进行一次全果喷洒;
5)将上述喷洒后保鲜剂的无花果放入烘干箱内,控制烘箱内温度为60-80℃,然后将其放入其中,烘烤直至果实上的保鲜剂干燥且果皮出现皱褶后,取出;
保鲜剂选用:壳聚糖1-3g、茶多酚2-5g、绿茶粉3-4g、花椒提取物2-3g、海藻酸钠1-3g、山梨酸钾2-3g、乳酸2-4g、酒石酸钠3-4g、茶皂素1-3g、柠檬酸1-3g、硫酸亚铁2-3g、碳酸钠4-5g、去离子水600-800g进行混合搅拌后,复配制得;
6)取一浸烫罐,在罐内加入清水,加热至沸腾,然后将步骤5处理后的无花果放入其中,浸烫6-8min;
7)待上述步骤4浸烫结束后,迅速将无花果取出,然后放入冰水中迅速冷却无花果,然后取出,晾干;
8)将步骤7中冷却后的无花果置于真空低温热风干燥机中,控制温度在80-90℃,然后在风口处设置消毒熏香,干燥至无花果是含水量在6-8%时,即可停止干燥,收集;
所述的消毒熏香采用:苦参提取物2-3g、花椒提取物1-3g、蛇床子提取物2-3g、桉树木粉30-40g、樟树木粉10-20g、明胶基质15-25g进行搅拌复配后,制备得到;
采用植物源熏香进行烟熏处理,保证了无花果干表面没有细菌滋生和残留,提高保存时间,保证了产品的养分不会流失;
9)将收集后的产品置于冷库中,控制温度为1-2℃、湿度25-35%,密封保存2-3天后,取出,采用真空袋包装即可。
本发明的有益效果是:采用本方法生产的无花干果制品,能够充分保留无花果的营养物质,提高了无花果的延伸产品种类,避免无花果因成熟周期短、易腐烂导致的资源浪费,本方法操作简单、易于掌握,成品食用方便、含有苹果酸、柠檬酸、脂肪酶、蛋白酶、水解酶等,能帮助人体对食物的消化,促进食欲,又因其含有多种脂类,具有润肠通便的效果。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施例,进一步阐述本发明。
