The wheatgrass cultivation method adopted by TOF is unique as it is a combination of close and controlled environment, aeroponic cultivation and the use of biotechnology.
Growing wheatgrass under a closed and controlled environment (also known as photo-bioreactor) allows controlled light and temperature to stimulate the growth of wheatgrass. For the development of green tissues of leaves, nutrient absorption through the leaves is considered faster than through root absorption. Growing wheatgrass under close and aeroponic conditions require nutrients to be available in the air moisture to be absorbed by the leaves. The nutrients in the air moisture are sourced from organic materials derived from plants, hence the whole cultivation process is free of inorganic chemical fertilizer and pesticide.
Wheatgrass products produced by The Origin Foods Sdn Bhd ("TOF") are in powder form and it is made from the unique cultivation, drying and manufacturing process. The advantage of the powder form is that nutrients are more stable and the nutrients do not reduce as fast as compared to wheatgrass juice. Furthermore, the wheatgrass is packed in aluminum foil packaging to prevent oxidation. No preservatives are required in wheatgrass formulation.
The uniqueness of the wheatgrass powder produced from TOF is in its low temperature drying and method whereby wheatgrass leaves are dried at a lower temperature compared to the conventional method which dries at a higher temperature. Even during the spray drying of wheatgrass concentrated liquid into fine powder, this process is treated under low temperature. As such, naturally occurring enzymes are more stable and do not denature.
