The ripening event of ethephon

Mr. Zhang Xiyan, chief scientist of the National Banana Industry Technology System and secretary-general of the Provincial Banana Association, said that in April 2011, after a media outside the province filmed the banana ripening operation in a farmers market storage warehouse in Shenzhen, no After asking experts for confirmation, they came up with the statement that "mistaken ethephon will cause vomiting, nausea and burning sensation, and long-term use is harmful to the human body", insinuating that bananas using ethephon ripening technology will have food safety issues and will Toxic to the body.

Zhang Xiyan said that after the media reported this matter, some large banana growers, banana purchasers, and dealers received mobile phone text messages from strangers saying that "banana prices will drop sharply in the near future." He I also received a similar text message on my mobile phone. Zhang Xiyan believes that this may be a carefully planned "conspiracy" and there may be someone behind the scenes.

Zhang Xiyan said that this false report is a misunderstanding of banana ripening technology and has misled some consumers.

Adverse effects: Banana prices have fallen again and again in some provinces and regions

Professor Chen Weixin, a scientist in the national banana industry technology system, analyzed that false reports by a certain media have caused serious damage to the national banana market. As a result, banana prices in some provinces and regions fell again and again within a week. A week ago, the purchasing price of bananas was 3.6 yuan/jin. This false report caused the price of bananas to drop rapidly to 1.5 yuan/jin. After that, banana prices dropped to varying degrees every day. Chen Weixin said that without the driving forces behind the scenes, banana prices would not have fallen so fast.

A staff member of the National Banana Industry Technology System said that banana planting in my country is mainly concentrated in Guangdong, Guangxi, Yunnan, Hainan and other provinces and regions. Bananas in Guangdong, Guangxi and other provinces and regions will be on the market in September. October. The banana planting area in Hainan is about 700,000 acres, and the annual output is about 1.2 million tons, accounting for about 15% of the country's annual banana output. Hainan's bananas have begun to come on the market one after another, and May and June are the time when bananas are concentrated. This false report has a negative impact on Hainan's The banana industry had a serious negative impact.

Experts refute rumors: Ethephon ripening technology is scientific and safe

In order to clarify the truth and eliminate public misunderstandings in a timely manner, yesterday afternoon, the National Banana Industry Technology System and the Hainan Banana Association A symposium on "Safety of Banana Ethephon Ripening" was held at Hainan University.

Zhang Xiyan said that under normal circumstances, bananas must go through a ripening process after harvesting so that various nutrients can be fully transformed. This is determined by the biological characteristics of bananas themselves. Ethephon ripening is an indispensable production step before bananas are put on the market. It has been widely used in banana production around the world for many years. Ethephon ripening technology is scientific and safe. Using ethephon to ripen bananas will not cause any harm to human health. Hazardous, there are no food safety issues.

Zhang Xiyan said that using ethephon only uses the ethylene gas emitted after it is dissolved in water to accelerate ripening, and induces the endogenous ethylene of the banana itself, causing the banana itself to quickly produce ethylene gas and accelerate self-ripening. The ripening process of ethylene is a complex plant physiological and biochemical reaction process, not a chemical process, and does not produce any substances that are toxic to the human body.
