青辣椒,茎圆柱形,疏生散刺。叶掌状,裂片阔至狭,托叶线形,被疏硬毛。花单生于叶腋间,花梗疏被糙硬毛,小苞片钟形;花萼钟形,密被星状短绒毛;花黄色,内面基部紫色,蒴果筒状尖塔形,种子球形,具毛脉纹。青辣椒,素有蔬菜王之称,有极高的经济用途和食用等价值。青辣椒收获季节当地市场上的青辣椒供大于求,而淡季又紧缺。更不用说把青辣椒远距离运送到省内外的市场上满足消费需要,存在保鲜保质的问题。果蔬速冻技术的先进性在于无污染且又能较好较长期地保持其原有品质。因此对青辣椒的速冻保鲜,具有现实意义。
发明内容
针对上述现有技术存在的问题,本发明提供一种速冻青辣椒的加工工艺,使得青辣椒在保险保质状态下较长时间储存。
为了解决上述技术问题,本发明采用如下技术方案:一种速冻青辣椒的加工工艺,包括如下步骤:包括青辣椒块选取、杀菌、速冻工序;具体方法如下:
(1)青辣椒块选取:
(11)、原料精选:精选出无腐烂、无病虫害、没有异色斑疤青辣椒作为加工原料;
(12)、原料切根、修边:
(2)盐水浸泡护色:将气泡清洗过的青辣椒放入盐水中护色;
(3)、气泡清洗:流水气泡清洗、清水喷淋,直到能将青辣椒块表面杂质,且捞清洗槽内漂浮的异物和杂质;
(4)杀菌,
(41)、药液杀菌:将分检合格的产品用含氯量为200ppm的溶液浸泡不少于10分钟杀菌,随时监测有效氯浓度并保持200ppm;杀菌后产品的细菌总数≤100000cfu/g,大肠菌群≤30MPN/100g;
(42)、漂烫杀菌:使用的是带式漂烫机,用漂烫池漂烫,水温98℃以上,漂烫时间为60-90秒,进一步杀菌;
(43)、常温清洗:清洗并冷却青辣椒块,把通过漂烫池的青辣椒块再次用常温水清洗,用常温池清洗,洗掉残留的氯,以闻不到氯的气味为准;
(44)、振动沥水,启动机械鼓风和振动沥水设备,进行振动沥水;
(5)预冷水冷却:清洗并冷却青辣椒,把通过漂烫的青辣椒用温度在10摄氏度以下的,水清洗,冷却时间在80-100秒,冷却后的产品温度在10摄氏度以下;
(6)速冻:在零下25℃以下和15分钟以内的时间期间急速冷冻,
(61)、冰水冷却速冻:采用流态化速冻机,水温根据流态化速冻机的速冻隧道温度选定,如速冻隧道温度高于-30℃,冰水池要制冷,制冷温度控制在0℃-5℃,如速冻隧道温度低于-30℃,冰水池用常温水;
(62)、做冰膜:将从速冻隧道出料口接出的青辣椒块直接放入盛有温度低于4℃的冰水容器中,时间为1-3秒,让青辣椒块表面有晶亮感,即做好冰膜。
作为上述方案的进一步优化,所述盐水中包括盐、明矾和水;所述盐、明矾和水的质量比为100:3:0.2。
作为上述方案的进一步优化,将包装好的产品放入-18℃冷库中冷藏,对空库房用次氯酸钠消毒保持清洁,产品放进库房后,库温保持-18℃;包装后在零下18℃以下的连续低温条件下保存和送抵消费点。
与已有技术相比,本发明的一种速冻青辣椒的加工工艺的有益效果体现在:
(1)本发明的一种速冻青辣椒的加工工艺,速冻青辣椒完全以低温方式来保持鲜青辣椒原料的品质,而不需要借助任何防腐剂或添加物,速冻运输中不会丢失生青辣椒中的营养,既保留了青辣椒的原汁原味,又方便产品存储及运输。加工过程中消除了杂菌感染的条件,得到的产品既符合绿色食品卫生要求,又解决了青辣椒在不变质要求下的储藏、运输和销售的问题。
(2)本发明的本发明的一种速冻青辣椒的加工工艺,速冻工艺易于标准化、适合大规模速冻存贮运输。对提高企业产品竞争力,有效扩大市场份额,推动企业技术创新和技术进步等都具有重大的现实意义和社会意义。
