Abstract

本发明属于水果保鲜领域，具体涉及一种木瓜保鲜方法，包括如下步骤，1）待木瓜长至7‑8成熟之前的3‑5天将电解食盐水均匀喷雾在木瓜上，每天上午、下午各一次，喷至木瓜上有水滴滴落为止；2）待木瓜长至8成熟进行采摘，采摘当日不在喷雾，对采摘好的木瓜进行挑选分级，去除烂果、将整理好的木瓜放入保鲜剂中浸泡10‑20min，然后轻轻捞出，沥干表面浸泡液；3）将步骤2）中浸泡后的木瓜套袋、装箱，放入冷藏室中，调节冷藏室的温度使得木瓜以3℃/h的降温速度降温，直到将木瓜表面温度降至3‑5℃，停止降温，在3℃下恒温保藏。本发明的方法能有效保持木瓜品质，并能延长木瓜贮藏期。

Description

木瓜保鲜方法
技术领域
本发明属于水果保鲜领域，具体涉及一种木瓜保鲜方法。
背景技术
木瓜果实脆而多汁，营养丰富，一般在春末、夏季采收，而未采用保鲜预处理的木瓜在常规贮藏过程中果肉会很快发绵变软，品质劣变迅速，营养价值降低。木瓜采摘后软化和褐变是贮藏中常见的问题，因此，延缓果实软化和减少褐变产生，意义重大。
发明内容
本发明的目的是提供一种木瓜的保鲜方法，该方法能有效延长贮藏期，防止木瓜产生褐变、腐烂、果肉皱缩、口感下降的问题，很好的保持木瓜的可溶性固形物含量和硬度。
本发明提供了如下的技术方案：
一种木瓜保鲜方法，包括如下步骤，
1）待木瓜长至7-8成熟之前的3-5天将电解食盐水均匀喷雾在木瓜上，每天上午、下午各一次，喷至木瓜上有水滴滴落为止；
2）待木瓜长至8成熟进行采摘，采摘当日不在喷雾，对采摘好的木瓜进行挑选分级，去除烂果、将整理好的木瓜放入保鲜剂中浸泡10-20min，然后轻轻捞出，沥干表面浸泡液；
3）将步骤2）中浸泡后的木瓜套袋、装箱，放入冷藏室中，调节冷藏室的温度使得木瓜以3℃/h的降温速度降温，直到将木瓜表面温度降至3-5℃，停止降温，在3℃下恒温保藏。
优选的，所述步骤1）中电解食盐水为食品级电解食盐水，pH为3-5，有效氯浓度为30-50mg/L。
优选的，所述步骤2）中保鲜剂按重量份计包括，丁香酚10-20份、肉桂酸20-30份、柠檬酸5-9份、咖啡酸5-10份、维生素E 10-20份、蜂胶20-30份、氯化钙5-9份、淀粉8-14份、保湿剂3-5份和纯化水600-800份。
优选的，所述保湿剂选自丙三醇、山梨糖醇和木糖醇中的一种或者他们的混合物。
一种木瓜保鲜剂的制备方法，将纯化水置于搅拌机中，在20-30℃下，以50-60转/min的转速搅拌3-5 min，在搅拌状态下依次将丁香酚、肉桂酸、柠檬酸、咖啡酸、维生素E、蜂胶、氯化钙、淀粉、保湿剂加入至搅拌机中，添加完毕后，升温至50-60℃，将搅拌机转速调至800-900转/min继续搅拌，当搅拌液颜色色泽均匀时，关闭搅拌机，即得所述保鲜剂。
本发明的方法能有效保持木瓜品质，并能延长木瓜贮藏期；本发明的方法实用灵活，可进行短、中、长期贮藏，采收后未经保鲜剂浸泡的木瓜可进行短期保鲜贮藏；采收后经保鲜剂浸泡处理的木瓜可进行中长期保鲜贮藏，采收后经保鲜剂浸泡处理、冷藏贮藏的木瓜可进行长期保鲜贮藏。
