Ethylene gas (C2H4=CH2)
is a harmless, odorless, colorless, gas that is produced from both natural and
man-made sources, and that has a profound effect on the freshness of produce.
The ethylene gas molecule is very reactive and Bluapple Produce Saver oxidizes
it into a state harmless to fruits and vegetables.
The effects of ethylene gas on
produce were discovered by accident. For years, lemon growers had stored newly
harvested green lemons in sheds kept warm by kerosene heaters until they turned
yellow and ripened enough to deliver to market. When new electric heating
systems were installed, the lemons no longer turned yellow on time.
Investigation soon found that the critical factor in the ripening process was
the ethylene gas given off by the burning kerosene in the heaters. In fact, it
was discovered that fruits and vegetables actually produce ethylene as
Experts believe that ethylene gas
acts as a signal to other plants to synchronize and coordinate ripening,
maximizing the appeal of the plant to their seed disseminators (e.g. birds) and
assuring the dispersal of their seeds. Scientists have since studied the
effects of ethylene gas on produce and found that the effects are widespread.
Even after harvest, fruits, vegetables and flowers are still alive, continuing
their biochemical processes, including ripening and the generation of ethylene
gas. Bruising or cutting some fruits and vegetables can even cause them to
increase their ethylene gas production. For more information CLICK HERE.
The industry has developed
technology to manage the amount of ethylene gas in order to accelerate or slow
down ripening and spoilage. Commercial warehouses, ships, and trucks are nearly
all fitted either with ethylene absorption technology or ethylene generation
machines. When you buy fruits and vegetables and bring them home, they sit on
your counter or in your refrigerator where ethylene gas accumulates and
accelerates the ripening process. Experts say average households throw
away over $600 worth of produce each year due to accelerated spoilage
from ethylene gas.
Bluapple® has been developed
to bring industry technology to your home, save you money, and reduce
food waste. Bluapple® has been thoroughly tested. You can click HERE to download a copy of the

Sodium permanganate (NaMnO4) is a
safe, inert compound used in a number of familiar applications such as in
drinking water treatment systems, and when combined with ethylene gas it reacts
and changes into a harmless manganese oxide (a sort of “rust”) and carbon
dioxide. Sodium permanganate is a safe and effective oxidizer, but we still
need a way to deliver it to where ethylene gas exists. Bluapple® uses natural
clinoptilolite, commonly known as zeolite as the carrier medium. Zeolite is
volcanic ash that has been turned to rock over eons. Although there are
numerous forms of zeolite, Bluapple® uses a form which is highly porous and
possesses a very high total surface area.
When the sodium permanganate is
applied to this pure zeolite using a special proprietary process, the
result is a highly effective ethylene gas absorber that also has an extremely
long life. Bluapple® has the highest percentage of available reactant
and the longest life per gram of any other ethylene absorption product.
The NaMnO4 impregnated zeolite
granules are then packaged in special membrane packets that are water
resistant, but are highly permeable to ethylene gas, and these packets are then
encased in our patented plastic Bluapple® shells in order to maximize airflow
into and around the packets.
Each Bluapple® is designed to last
up to three months assuming a typical household volume of produce use. We
recommend that two Bluapples be used at the same time for a typical household
in order to maximize the absorption effectiveness, though for smaller
households one may provide ample protection. Full Year Refill Kits for your two
Bluapples are available on our website.
When it is time to replace the
packet, don't throw the spent zeolite granules away! We recommend that you put
the spent zeolite granules in your houseplants or in your garden. They are a
natural soil and the residual MnO2 provides trace minerals to the soil. Your plants
will love it.
