发明内容
本发明的目的在于现有技术的不足,提供一种冻干黄瓜片的制备方法,其制备得的黄瓜片可即食,且无任何添加剂。
本发明所采取的技术方案是:一种冻干黄瓜片的制备方法,其包括如下工艺步骤:
1)冷冻:将原根黄瓜置于冷藏库冷冻处理30~45min,洗净后消毒处理,再干燥至硬化,待切片;
2)配制糖液:将蜂蜜和黑糖浆混合搅拌均匀,控制温度在20~25℃范围内,加入柠檬酸继续搅拌,搅拌时间为10~20min,得糖液;
3)切片:将步骤1)所得原根黄瓜去除头部和尾部后切片,再将切片平铺后进行单面针刺处理,得黄瓜切片;
4)真空渗糖:将步骤2)所得糖液与步骤3)所得黄瓜切片以1:1比例进行浸泡处理,待黄瓜切片充分浸泡糖液后,进行真空吸附处理,控制真空度为0.2~0.3MPa,吸附时间为30~40min,然后常压静置20~30min,将静置后的柠檬片捞起,自然沥干10~15s糖液后,得半成品;
5)将步骤4)所得半成品经速冻、真空冻干、微波杀菌处理,得成品。
作为上述方案的进一步改进,步骤1)中所述消毒处理为用浓度为8~12%的氯化钠溶液浸泡30~45s后再用流动水漂洗10~15s。
作为上述方案的进一步改进,步骤2)中所述蜂蜜和黑糖浆的混合比例为1:1.2。
作为上述方案的进一步改进,所述蜂蜜选自椴树蜜、洋槐蜜、荆花蜜、百花蜜、枣花蜜、桂花蜜中的至少一种。
