Cultivating the Best of the Best

The conditions and environment in which North Atlantic seaweeds live in the wild can be described as anything but hospitable, and only the most robust plants flourish and prosper. The clean waters of the Canadian North Atlantic Ocean offer a particularly complex combination of nutrients, wide temperature and tidal fluctuations, and various other conditions that seaweeds endure.

With this in mind, Acadian Seaplants developed a unique cultivation system - one that compliments and mimics the favourable conditions found in the wild while minimizing or eliminating the stresses that affect seaplant growth and quality. This proprietary cultivation technology took many years to perfect.


There are many advantages to our proprietary, land-based tank farming system:

  • We thoroughly monitor and control every factor required to consistently yield high quality sea vegetables, crop after crop. Every aspect of the operation from seedstock cultivation through to packaging and shipping is traceable.
     
  • Located along the pristine North Atlantic coastline of southern Nova Scotia, Canada, our cultivation system is continuously supplied with fresh, pure, clean seawater from the marine plant's native habitat. The water is further micro-filtered upon entering and exiting our system as an additional quality safeguard.
     
  • The design of our seedstock nursery, cultivation system and our innovative growing techniques ensure purity, as only our specific seaplant strain is found in our culture tanks.
     
  • We accurately plan our crop production each growing season. This allows us to provide a secure supply with the ability to manage production in response to our market needs. The system is modular in design and we can increase our cultivation capacity by adding more tanks.
     
  • It is a sustainable and renewable operation. Our innovative equipment and processes ensure that we can continue to produce the Hana-Tsunomata™ sea vegetable line indefinitely, and in an environmentally responsible manner that does not interfere with, or overwhelm the ecosystem.
     

The Best of the Best

We selected the specific strain of Chondrus crispus we use as our seedstock after an extensive screening program of many wild strains found in the Canadian North Atlantic Ocean. This particular strain is unique and does not grow abundantly in the wild. It can be thought of as representing the "best of the best" for the characteristics needed to produce our Hana Tsunomata™ lines of Pink (Aka), Green (Midori) and Yellow (Kiku) sea vegetables.

The first step for each new crop occurs indoors in our pristine nursery where our juvenile seaplants grow into successively larger culture tanks. Once the plants outgrow the largest of these indoor vessels they are then moved into covered greenhouses. When the climate is ideal, they are moved to outdoor tanks. One by one, the seaplants outgrow each successive tank until the entire network of tanks is filled.

We harvest our crops once the seaplants reach their peak and all of their desired characteristics are at their best. Each tank is managed by our skilled cultivation team to carefully and quickly harvest the crop.

 

Farming 'Sea' versus 'Terrestrial' Vegetables

The most popular sea vegetables on the market today have been cultivated for generations in open ocean water farms, a form of aquaculture, and primarily in Asia. They use seedstock derived from wild seaweeds adapted to grow in the open ocean. Acadian Seaplants has taken the farming or "aquaculture" of sea vegetables to a new, higher level of cleanliness and product traceability through the concept of land-based cultivation tanks.

The terrestrial (land) vegetables we know and love to eat are also grown from seedstock originally adapted from wild plants discovered centuries ago. Just as the highest quality, most sought-after produce is now grown in controlled greenhouses to provide the highest quality, Acadian Seaplants has adapted sea vegetable cultivation to onland tanks. The cultivation facility replicates and perfects the seaweed's natural ocean-growing environment to reliably produce pure, clean, and beautiful crops of Hana Tsunomata™ sea vegetables. The entire crop cycle actually lasts more than one year and is but one more of Acadian Seaplants' science-based innovations in cultivation techniques.

Producing Hana-Tsunomata™

Strict protocols govern the handling of our freshly harvested crops to ensure each new batch meets our standards for Pink (Aka), Green (Midori) and Yellow (Kiku) Hana Tsunomata™ sea vegetables.

Color Setting

Throughout the growing season, we closely monitor each crop throughout the growing season and only harvest it when the cultivation tanks are full and the seaplants achieve all of the desired characteristics.

The newly harvested plants are gently washed and handled to set for the exact pink, green or yellow colour standards for each batch. There are no colours or dyes added to the product.

Dehydration

Each batch is separated and then passed through a custom-designed, low temperature dehydration process. This gentle drying method reduces the moisture content to a stable level while preserving the shape, colour, texture and nutritional value of each plant.

Separating and Sorting

Quality is our number one priority, and quality assurance is built into every step of our cultivation and production processes. As an extra guarantee, we have also put into place a state of the art separating and sorting system to ensure only the highest quality Hana Tsunomata™ is present in our final packaging.

An electronic colour sorter ensures that each plant (frond) in the batch meet all colour specifications. Our system includes size resolution imaging, object based processing, shape detection and an intelligent air ejection system.

Electronic air separators are calibrated to ensure absolute cleanliness. The Hana Tsunomata™ pieces are then passed through a magnetic sorter to further ensure quality. Conveyor belts move the finished batches through a team of skilled food quality technicians for final verification of product cleanliness.

The Hana Tsunomata™ sea vegetables are now ready for final packaging.
