要谈反季节蔬菜的安全性,还是让我们先来简短地了解一下,这些违反季节规律的蔬菜究竟从何而来,主要又是在哪些方面发生了变化。从来源来看,所谓的反季节蔬菜无非有三类:第一类是从遥远的南方跋山涉水运送而来的蔬菜,比如云南、海南出产,被运至北国的应季辣椒、番茄;第二类是从冷库里搬出来的应急储备,比如出镜频率极高的蒜薹;第三类则是最容易碰到的大棚蔬菜——只要保证温度和湿度,蔬菜们照样会在隆冬时节伸枝展叶,开花结果。 To talk about the safety of off-season vegetables, let’s start with a brief look at what happens to vegetables that violate the seasonal laws, and where are the major changes? From the source point of view, the so-called anti-seasonal vegetables are nothing more than three categories: The first is from the far south of Heba wading vegetables, such as Yunnan, Hainan produced, was shipped to the North of the season pepper, tomato; the second is The emergency reserves that come out from the freezer, such as garlic sprouts with a high frequency of appearance, and the third one are the most easily encountered greenhouses - as long as the temperature and humidity are guaranteed, the vegetables will still show their branches and leaves during the winter season. .
