Description
【技术领域】
本发明属于一种果脯的制作方法,具体涉及一种火龙果果脯的加工方法。
背景技术。
火龙果果实形状多似心脏形和椭圆形,成熟时果皮呈天然色,有的带有紫色条纹,有淡雅的清香,果肉清爽多汁,风味独特。它具有高蛋白、低糖、低脂外,还富含维生素C,以及多种人体所必需的微量元素,尤其是硒、钙的含量大大地高于其他的果实和蔬菜。因此火龙果有抗癌、抗衰老、降血压、降血糖、消炎、补钙、美容等功能;还可加工成果汁、饮料、口服液、罐头等产品,具有很大的开发价值。火龙果鲜果果为多汁浆果。由于含水量比较高,所以储存、运输都比较困难,果脯的制作就是除去部分水分,果实干制过程中所除去的水分主要是游离水和部分胶体水,现有的果实干制的方法是自然干制法,自然干制法具有生产效率低、工人的劳动强度大、成品率低等不足。
【发明内容】
本发明提供一种火龙果果脯的加工方法,利用本方法生产的火龙果果脯口感佳,营养成分流失少。本发明是以如下技术方案实现的:
一种火龙果果脯的加工方法,其特征在于包括以下内容:
(1)用流水清洗火龙果果实,;
(2)将清洗后的火龙果果实进行护色处理;
(3)将护色后的火龙果果实进行烘干处理;
(4)将烘干后的火龙果果实进行杀菌处理;
(5)将杀菌后的火龙果果实进行包装,即得火龙果果脯成品。
进一步地,步骤(2)中所述的火龙果果实为火龙果整果。
进一步地,步骤(2)中所述的火龙果果实为成熟度为7~8成熟的火龙果整果。
进一步地,步骤(2)中所述的护色处理包括以下内容:将火龙果果实倒入含有0.3~0.6%质量分数的维生素C水溶液,在10~25℃下保持5~10min。
进一步地,步骤(3)中所述的烘干处理为:将火龙果果实放在烘盘中,在65~75℃下保持8~10h,烘干后的火龙果果实含水量为15~20%。
进一步地,步骤(4)中所述的杀菌处理包括以下内容:将火龙果果实放在密闭、干燥的空间内,用紫外线进行杀菌7~8h。
本发明的有益效果如下:
1.本发明提供的火龙果果脯的加工方法中,选用的是成熟度为7-8成熟、无病虫害、无腐烂的火龙果果实,选用这样的果实加工的成品质量较好而得率也较高;此外,本发明还选用带有果蒂的火龙果整果,使得加工的果脯果形完整,保证果实和果蒂尽量多的营养物质,保障其药用价值。
2.本发明提供的火龙果果脯的加工方法中,采用流水清洗,比一般的清洗能更有利于去除赃物和杂质,且能减少因清洗而对火龙果果实带来的损伤。
3.现有技术中,加工火龙果脯时都有去除果皮的操作:先用碱液脱皮,再用酸液中和。这样不仅会损害火龙果果实的营养成分,并且操作复杂,所用的碱液还会对人体皮肤造成腐蚀。本发明提供的火龙果果脯的加工方法中,并没有进行去除果皮的处理,操作更为安全、简单,并且保留了火龙果果皮的营养成分:果皮中富含多种人体所需要的氨基酸,维生素等,其中硒的含量较高,可以防治咽喉炎,还有肠胃不适等。
4.传统的火龙果果脯加工过程中,常常采用亚硫酸氢钠溶液浸泡、甚至硫磺熏蒸的方式,以达到护色的效果,造成果脯中残留有害物质,威胁人体健康。而本发明提供的火龙果果脯的加工方法中,采用维生素C进行护色处理,由于维生素C的抗氧化作用,防止火龙果果实的褐变,进一步保证加工出的火龙果果脯色泽天然;由于维生素C属于人体的营养物质,用它来处理火龙果果实,不仅不会造成有害物质残留,反而会增加果脯的营养。
5.本发明提供的火龙果果脯的加工方法中,烘干时采用的温度和时间,有利于保证火龙果的营养成分流失少,并且使加工的火龙果颜色天然,有透明感。
6.本发明提供的火龙果果脯的加工方法中,还采用紫外杀菌的处理,使得加工的火龙果果脯更安全卫生,更有利于人体的健康。
7.用本发明提供的方法加工火龙果果脯,操作简单、安全,自动化程度高,利于大量的工业生产;加工的果脯果形完整、颜色自然、有透明感;加工的果脯无任何有害添加剂,果实的营养成分流失少,有火龙果天然清香,口感佳。
【实施方式】
下面结合实例对本发明作进一步说明。
