Controlled atmosphere during transportation: why is every line not using it?

Author(s) : LAWTON A. R.

Summary

Following a brief presentation of the history and theory of controlled atmospheres, the author discusses gene regulation of ripening, modified atmospheres in transport, and passive and active controlled atmosphere systems, before addressing the question put in the title. He concludes that this is no doubt as to the effectiveness of controlled atmospheres for climacteric fruit. However, it is difficult to justify the cost of the technology for a commodity that could be transported adequately in refrigerated air storage. There is certainly an application for chill-sensitive apples where there is insufficient storage life at their minimum storage temperature, and for bananas of uncertain maturity. Transport of non-climacteric commodities with short storage lives would benefit from any technique that could be used to increase their useful life. Unfortunately, such commodities often have to be harvested at maximum maturity, and although affected by controlled atmosphere, the shelf life extension is usually no more than 50%.
