水果罐头以用料不同而命名不同,一般水果罐头的原料取材于水果,包括黄桃,苹果,荔枝,草莓,山楂等。产品主要有黄桃罐头、草莓罐头、橘子罐头等。
罐头需要保存时间较长,就需要对其内部进行杀菌保鲜,使水果罐头内部水果不变质,可以使罐头的保存时间更加长久,同时需要对水果罐头进行保鲜,从而使罐头的口感更佳,不受影响,但现有罐头多为孩子的最爱,添加糖分较高,对于孩子的生长发育造成一定的影响,对其牙齿的发育也造成了一定的影响。
发明内容
(一)解决的技术问题
针对现有技术的不足,本发明提供了一种水果罐头无菌保鲜方法,解决了水果罐头无法进行较好的无菌保鲜的问题。
(二)技术方案
为实现以上目的,本发明通过以下技术方案予以实现:一种水果罐头无菌保鲜方法,包括以下步骤:
S1.挑选水果:挑选新鲜、完整的水果,清洗、去皮、去除果核,将其切割成合适的大小;
S2.水果处理:蒸煮,将水果内部的细胞进行失活,避免其进行生存,同时破坏水果细胞壁,使糖分便于进入,而且将果肉内部的一些细菌与酶进行灭杀,形成初步灭菌;
S3.装罐:将蒸煮好的水果块,装入合适的罐中,通过向其中加入合适的浓度的糖水,同时加入保鲜液,同时向其内部加入少许的盐水,将罐体送入高压蒸汽灭菌装置,进行二次灭菌,最后将罐体内部抽成真空,进行密封保存;
S4.灭菌:将装罐后的水果,经过水浴加热,进行再次灭菌,符合巴氏消毒法,冷却后,然后通过将干燥装置,将罐体表面的水分蒸发;
S5.保存:通过将罐体放置于阴凉、遮阳处进行保存,运输时轻拿轻放。
优选的,所述保鲜液包括柠檬酸、乳酸钠、谷胱甘肽配比而成,所述蒸煮的温度为95℃~100℃,所述柠檬酸、乳酸钠、谷胱甘肽按照重量分为:柠檬酸0.5~1、乳酸钠1~3、谷胱甘肽1~2。
优选的,所述灭菌用水经过冷却用作清洗水果用水,所述盐水的浓度为0.25g/ml,所述盐水的用量为每千克水果2~4ml。
优选的,所述糖水所用糖为黄原胶与木糖醇,所述黄原胶与木糖醇的占比为1:4,所述黄原胶与木糖醇的量为每千克水果50~100g。
优选的,所述加压的压力值为0.8~1个大气压,所述加压时间为15~20分钟,所述两次加压时间间隔为5~10分钟。
优选的,所述柠檬酸为柠檬、柑橘、菠萝中提取,所述乳酸钠通过植物发酵、中和得到,所述谷胱甘肽由小麦胚芽中提取得到,且为还原型谷胱甘肽。
(三)有益效果
本发明提供了一种水果罐头无菌保鲜方法。具备以下有益效果:
1、本发明,通过设置有保鲜液,可以有效阻止水果内部的成分与外界物质进行反应,从而导致水果变质,无法食用,且均为植物提取,安全、可靠,同时通过盐分与真空包装,阻止罐头内部与外界的交流,阻断水果与外界接触的来源,实现较好的保鲜效果。
2、本发明,通过三次灭菌操作,使灭菌更加彻底,其中通过高压蒸汽灭菌,在进行灭菌的同时,加快糖分、保鲜液与水果内部的分子交换,加快了罐头的形成过程,口感更好。
3、本发明,通过将白砂糖、冰糖等更换为木糖醇与黄原胶,可以对水果进行有效渗透,阻碍微生物的生长,达到长久保鲜的目的,同时可以减少糖分的摄入,保护人体的健康。
