We are often asked why Pines products have a 5-year shelf life when greens in plastic bottles only have a 3-year shelf life. The difference is we use glass bottles with special metal caps that allow us to remove the oxygen from each bottle in a similar manner used for food storage containers that have a 10 year shelf life. Actually, without oxygen, a product could stay fresh indefinitely! After five years, a green superfood from Pines is still vibrant green while one in a cheap plastic tub has turned brown or a dull grey color.
We all need oxygen. Highly pigmented vegetables Pines Wheat Grass, Green Duo and Mighty Greens help better utilize oxygen because they increase Nitric Oxide levels for greater stamina, endurance and recovery. Leading nutritionists and even the USDA point to research that shows 9 out 10 people do not eat enough vegetables for the health protection they provide.
Oxygen is essential for life, but when oxygen is in contact with wheatgrass powder and other highly-pigmented superfoods for months before being purchased, the nutrients slowly devitalize through the process known as oxidation. Thus, even though you must have oxygen to live, oxygen for long periods in containers with highly pigmented superfoods is not a good idea because the oxygen cause vegetable powders in plastic containers and paper packets to lose nutrition.
The effect of oxidation on sensitive green food nutrients was a great concern to Dr. Charles Schnabel, who was called “the father of wheatgrass” by Steve Meyerowitz, author of “Wheatgrass: Nature’s Finest Medicine.” Schnabel was the scientist behind medical research beginning in 1937, using whole food wheatgrass powder, that was the scientific basis for the books by Ann Wigmore and other authors. Schnabel used the same oxygen-free packaging used by Pines for the last 40 years. The tight-fitting metal caps allow the bottle to be tightly sealed between uses to help keep the product fresh after opening.
