食品卫生已成为人们一直关心的问题。最近发现不少银耳生产者不是从银耳生物学特性出发,栽培出色泽洁自的银耳子实体,而是非法地用工业硫磺进行熏蒸,来迎合情况不明的消费者心理,严重的给食用银耳带来污染。工业硫磺含砷量很高,在用硫磺蒸熏时,通过燃烧释放出砷,在此同时氧化成三氧化二砷,又称之为“砒”,大量附着在银耳上,使银耳实际含砷量大大超过食品检验的标准,从而对人体健康产生危害。所以,应当严禁用硫磺熏蒸银耳。被硫磺熏蒸过的银耳,往往子实体色泽黄自不一,子实体瓣内外色泽亦黄白相间, Food hygiene has become a problem that people are always concerned about. It has recently been discovered that many white fungus producers, instead of starting from the biological characteristics of Trefoil, cultivate their own clean, white fungus entities, but illegally fumigate them with industrial sulfur to cater to unidentified consumer psychology, severe edible white fungus strips To pollution. Industrial arsenic sulfur content is very high, sulfur smoked, the release of arsenic by combustion, at the same time the oxidation of arsenic trioxide, also known as “砒”, attached to a large number of white fungus, the actual arsenic content of white fungus greatly exceeded Food testing standards, which have a harm to human health. Therefore, it is strictly prohibited to fumigate Tremella with sulfur. Sulfur fumigated Tremella, often fruiting bodies vary in color, both inside and outside the fruiting body color is also yellow and white,
