STEVIA LEAVES

OUR GREATEST ASSET - OUR VARIETY

Before expanding into the commercial plantation phase we went through a meticulous stevia cultivar development program.

 

We collected several potential commercial varieties and conducted numerous field trials. We monitored the biomass and steviol glycoside yield of all the varieties for a few seasons and we were successful in identifying the best-performing variety for our agro-climate. We selected for physical characteristics linked to high biomass and steviol glycoside yield. We then went through a multi-generation genetic selection process to further improve the performance of the identified varieties.

NO SCOPE FOR QUALITY DETERIORATION
We raise all the planting materials in our own contracted facility under continuous specialist supervision. Our plants are multiplied by clonal cuttings for maintaining genetic integrity.
OPTIMISED CROP MANAGEMENT
We have optimised our agronomic practices and crop nutrition management system for the best leaf quality. We have a meticulously planned irrigation scheme targeted to provide optimal watering at different stages of growth ensures higher steviol glycoside content in our leaves. Efficient and balanced nutritional management is also essential to achieving higher leaf quality. We always prioritise quality over quantity.

MODERN POST-HARVEST PROCESSING

We use proprietary fluid bed drying systems for quickly drying our leaves with no quality deterioration. After drying, our leaves retain the green colour and do not caramelise. Correctly dried leaves ensure clean extracts and trouble-free downstream processing of the liquid extract to produce pure glycosides. We pack our dried leaves in hermetically sealed packages for long shelf life and minimal quality loss, extending shelf-life to at least six months.

100% TRACEABILITY
We maintain a total traceability chain in our nursery, farming and post-harvest processing operations.
LEAF QUALITY FOR HIGH EXTRACTION EFFICIENCY AND LOW PROCESSING COST

Our leaves are high in total steviol glycoside content with more than 70% Rebaudioside A - one of the best tasting and most commercially useful glycosides. The content of other desirable minor glycosides including Rebaudiosidea D and M are also higher than average.

The tannins, fats and wax content of our dried leaves are low preventing the need for pre-treatment of the leaves with organic solvents before water extraction.  A high content of glycosides in the leaves ensures low extraction and purification cost to produce globally competitive final products.

CONTINUOUS AND GUARANTEED AVAILABILITY
Through optimised operations we achieve a high leaf yield per hectare. Our modern agronomic management ensures at least 4 harvests per year, and 5 or 6 in our warmest climatic zones which ensures high quality Stevia leaves are available all year round.
