Frequently Asked Questions

  • Does this work for a regular fruit bowl?
  • BluApple will aggressively absorb ethylene gas from any environment it is placed in and will help protect produce in a fruit bowl or any non-refrigerated area. It works best if it is used in a closed environment where it can vacuum all the ethylene molecules from the entire space.
  • How does BluApple work?
  • In short, the ethylene gas molecule is very reactive and is readily oxidized into a state harmless to fruits and vegetables. A simple and safe method of neutralizing ethylene is to “oxidize” it with sodium permanganate.
  • Do I need to open the packets?
  • The packet itself is permeable to ethylene gas and it is not necessary to tear open the packets.
  • How I do I know if my BluApple has been used up?
  • BluApple packets contain small granules of the active ingredient. Using scissors, snip open a corner of the packet. When fresh and fully potent, the granules are purplish in color and when crushed the granules are a white/purple. You can cover the corner you have cut off with a small piece of cellophane tape to re-seal the packet.

About BluApple

A Fruitful Investment

No one likes wasting fruits and vegetables, yet the average family of four throws away as much as $600 worth of spoiled produce each year, according to the USDA (it’s not all that hard to imagine when an organic apple can cost $1.50). We’ve discovered an easy way to preserve the edible life of your produce, so you have more time to consume it instead of composting it. With this simple little product called BluApple, you can extend the storage life of produce by as much as threefold.

BluApple works by absorbing ethylene gas, which is given off naturally by fruits and vegetables. If ethylene gas builds up in your food storage area, it speeds the ripening process and accelerates decomposition. Entrepreneur Timmy Chou, who founded BluApple, was inspired by the science applied for years to prevent spoilage in industrial environments like ocean liners, trucks and warehouses. He created a consumer product that makes use of the same non-toxic active ingredient (sodium permanganate). Each BluApple can absorb ethylene gas in a typical home refrigerator, produce bin or storage container for about three months (after that, refill packets are available). Simply place a BluApple where you keep your fruits and vegetables, and then sit back and enjoy them. . . for much longer.
