Dartmouth, NS, Canada – October 30, 2024 – Acadian Seaplants Limited™, the parent company of Acadian SeaPlus™, is excited to announce a newly cultivated strain of the red seaweed, Palmaria palmata that offers wide ranging benefits for the health and wellness industry. Also known also by the common name dulse, this red seaweed is a good source of prebiotic dietary fiber and protein.

Some red seaweeds are known to contribute to overall gut health, resulting in many health benefits, including anti-inflammatory and neuroprotective activities.

Dr. Jeff Hafting, Acadian’s Senior Cultivation Research Scientist, explains, “The new cultivated seaweed is a result of years of careful research and development and comes at a critical time for the nutraceutical, food and beverage and cosmetics industries.”

Dulse Prebiotics

Most people are aware that regularly adding dietary fiber is essential for good health. The food industry usually sources dietary fiber from terrestrial sources, however, dulse (Palmaria palmata) is also a rich source of complex dietary fiber and this complexity sets dulse apart as a potent prebiotic.

Dulse contains the polysaccharide xylan as its main cell wall constituent, with proteins and minerals integrated within a complex matrix. This complex structure allows xylan to pass through the upper digestive tract, arriving in the lower gut intact where it acts as nutrition and substrate for our gut microbiota.

Xylan functions as a prebiotic, supporting a diverse and healthy probiotic microbial community within the gut. The polysaccharide contributes to your overall gut health by increasing short-chain fatty acid production by probiotic bacteria within the GI tract. The production of short-chain fatty acids from probiotic microbes is enhanced by the presence of dulse in the diet, and this results in many health benefits, including anti-inflammatory and neuroprotective activities.

A recent study with mice indicated that the diversity of probiotic bacteria was increased within the GI tract as beneficial probiotic Lactobacillus, Proteobacteria, and  dulse. Enhancing the diversity and health of probiotic gut microbiota led to increased production of short-chain fatty acids and these in turn influenced the gut brain axis. The gut brain axis refers to the bidirectional communication between the central nervous system and the gut linking emotional and cognitive centers of the brain with intestinal functions. This interesting study suggests that with the consumption of prebiotic xylan found in dulse, both gut and brain health may be enhanced. 

Lida Lindquist, Market Development Manager for Acadian’s Human & Animal Wellness’ specialty ingredients division, explains, “Consumers are increasingly looking to purchase sustainable sources of food and dietary fiber. Dulse has recently been domesticated by Acadian Seaplants Limited and is now being farmed in the world’s largest on-land cultivation system that does not adversely affect the natural environment and is highly productive and traceable and has attained several internationally recognized quality and food safety certifications. Also, sustainable wild harvesting of Dulse has been done for centuries around the North Atlantic where it is found in abundance. 

If you are looking for a new source of dietary fiber, dulse is a highly sought after marine algae that adds complex prebiotic dietary fiber to your diet, enhances gut health and positively influences the gut brain axis.”

Dulse Proteins

Proteins are key to the health and diet of humans—they are essential for creating enzymes, regulating hormones, moving oxygen throughout the body, building and repairing muscle, and fortifying bones and cartilage. North American consumers have developed a tremendous appetite for protein—and not just from poultry, red meat, fish, and eggs.

Dr. Hafting adds “The high protein content in dulse is one of the main reasons for growing commercial interest of this seaweed for food applications. When dulse is cultivated in a land-based operation, protein content can be sustained at over 20% with every harvest. This means you can have confidence that you are receiving an excellent source of protein with every purchase.”

Harvesting wild dulse has become a challenge due to increasing water temperatures and the scarcity of harvesters willing to undertake this physically demanding undertaking. Now that dulse has been domesticated in Acadian Seaplants’ on-land cultivation system, the natural environment is not adversely affected by harvesting, and the system is highly productive and traceable. The growing interest in sustainable resources for food, pharmaceuticals, and biomedical products allow dulse to play a key role because of the proteins that it possesses.
