Green Foods' Processing Captures Barley Grass Nutrients
The key to BarleyGreen’s nutritional superiority is
the result of organic farming methods and technical
know-how used to transform organic barley grass juice
into a concentrated, stable powder.
1. Grown “Right” From the Start
BarleyGreen is organically grown and processed in
Oxnard, California. Because of its unique geology,
Oxnard has one of the richest topsoils in the world.
The farming of Green Foods’ barley grass begins in
richly composted organic soil. No pesticides, herbicides,
or chemical fertilizers are ever used. Once the
soil is prepared, barley seeds are planted in rows to
wait for the perfect combination of water, oxygen and
temperature to sprout.
2.Harvested For Maximal Nutrition
The young barley plants are harvested just prior to
the jointing stage, the time at which they are the most
nutritious. The processing facility is just minutes away
from the fields and the entire process from harvest to
powder takes only 2-4 hours! This means that the
product is fresh, allowing little time for loss of nutrients.
3. Pure Water Rinse
Immediately after delivery to our processing facility,
the plants are rinsed with fresh, pure water and tumbled
dry. No heat, detergents, or chemicals are ever
used. This is unlike many other green products, where bleaches are
often used that may leave toxic by-products on the plants.
4. Gentle Juice Extraction
The nutrition of the barley grass resides in its juice,
not the insoluble fiber. The juice is separated from the
tough, fibrous outer leaf using a gentle, low-pressure
extraction process. The delicate plant cells and nutrients
are protected from destruction while the insoluble
fiber is returned to the field for composting.
5. Oxygen Removal
Plant juices, left on their own, will begin to oxidize
and within hours many important nutrients will be
lost. Using a vacuum evaporation system, the green
barley juice is concentrated and protected from oxidation
by removing excess oxygen and water. The next stop for the freshly extracted
juice is in one of four refrigerated 1,200 - gallon stainless steel
tanks. Organic maltodextrin, a complex carbohydrate derived from
corn and treated with enzymes, is added to coat and
protect the enzymes and other molecules so they will not chemically react with each other. After drying,
these carbohydrates form a protective matrix around
the juice particles to keep oxygen away from the proteins
and other delicate nutrients.
6. Spray Drying: the Most Important Step
The most critical step is the drying process
since many nutrients can be easily lost to heat and oxidation during this
stage. The concentrated green barley grass juice is pumped through an
atomizer and spun dry in warm air so that the juice particles do not
exceed body temperature.
7. Granulated for Solubility
The bulk powder is put through a granulation process where the fine powder
is transformed into larger, uniformly-sized granules making it easier to dissolve
when mixed with water or other liquids.
8. Quality Control
Each lot is inspected at different stages of production for taste, solubility, pH, protein,
chlorophyll, and microbial content. In addition, nutritional analyses and other quality
assurance tests are performed by independent offsite laboratories.
The Difference Processing Makes
- Organic cultivation
- Rapid processing
- Gentle juice extraction.
- Insoluble fiber is removed.
- Juice is spray-dried to protect the nutrients and
- The powder is granulated for solubility.
Cold Water Test for Fiber
- Mix powders in test tubes filled with cold water,
stir and leave sit for 10 minutes.
- Barleygreen stays in solution, while other powders
with insoluble fiber will settle to the bottom.
Hot Water test for Enzymes
- Mix powders in test tubes filled with hot water.
- The proteins in Barleygreen clump up because
they are intact proteins; other dissolves proteins
are already denatured. Enzymes are proteins and
exhibit activity only if they contain intact proteins.
