Asparagopsis

According to FAO, livestock sector is responsible for 18% of the total global
warming effect and cattle enteric methane emissions are considered one of the top contributors worldwide. Methane is a very potent greenhouse gas and its emission levels have been rising annually due to the growing livestock population. 

Struggling to find natural-origin feed additives to reduce ruminant methane emissions, scientists came across a red seaweed genus, Asparagopsis, that has a high potential to mitigate enteric methane production, since it produces high levels of bromoform, a halogenated compound known to inhibit methanogenesis. Published studies have shown that supplementing 0,2% of freeze-dried Asparagopsis to the animal’s diet has proven to reduce methane production in cows up to 98% and simultaneously improving their weight gain by 42% (Kinley et al., 2020).

Both studied species Asparagopsis armata and Asparagopsis taxiformis are non-indigenous macroalgae particularly abundant in the Azores (NE Atlantic), occurring in all the nine islands of the archipelago from the rocky intertidal up to 40 m deep.

seaExpert is duly licensed to harvest these species, working responsibly to
obtain the minimum impact on the Azorean marine ecosystem while supplying a high quality product. Harvesting is performed manually through scuba diving in a scattered and disseminated way and only within seasons that register the highest abundance and bioavailability rates, allowing the selection of the best specimens and avoiding by-catch.

In the past four years, we have supplied Asparagopsis to eight different
countries, delivering our algae to several research institutes, universities and private companies, in a joint effort to find a viable solution to combat climate change.

AS NOSSAS ALGAS

Asparagopsis armata

Asparagopsis armata

Medium-sized red seaweed, abundant in the Azorean waters. It´s widely used in the cosmetic industry, namely in antidandruff and anti-acne formulations.

Abundance season: March to May

asparagopsis taxiformes 2

Asparagopsis taxiformis

Medium-sized red seaweed, extremely abundant in the Azorean waters. Is has a chemical profile with good potential to be applied in human and animal health industry.

Abundance season: March to May

Gongolaria abies-marina

Medium-sized brown seaweed, abundant in all the Azorean archipelago. Traditionally used as a fertilizer, it has attracted interest for pharmaceuticals as an aid to muscle development and as a source of anti-inflammatory drugs.

Abundance season: March to June

Cystoseira humilis

Medium-sized brown seaweed, widespread in the Azorean archipelago. Its unique chemical properties has attracted interest from pharmaceutical, food and cosmetic industries.

Abundance season: March to June

Halopteris scoparia

Medium-sized brown seaweed, commonly found in the Azorean sublittoral levels. It´s a very important seaweed for the cosmetic industry, being used in skin treatment products.

Abundance season: October to March and June to July

Padina pavonica

Smal-sized brown seaweed, abundant in tide pools, sheltered intertidal areas and in the deep subtidal on all islands of the Azores. It is commonly used in many areas (human nutritition, cosmetics, pharmaceutical) due to its rich nutritional profile and high bioactivity levels, like antibacterial, antioxidant, antifungal, among others.

Abundance season: May to September

Pterocladiella capillacea

Medium-sized red seaweed, abundant in the Azores. It´s one of Azorean´s most harvested seaweeds for agar production in the food and biotechnology industries.

Abundance season: June to September

Sargassum vulgare

Medium-sized brown seaweed, widespread in the Azores. Commonly used in the agricultural industry for the production of fertilizers, but also in the cosmetic industry for the production of skin conditioning agents.

Abundance season: April to August

Zonaria tournefortii

Medium-sized brown seaweed, with strong presence in several Azorean islands. According to recent studies, it has a huge potential to be exploited in biotechnology, cosmetic and pharmaceutical industries.

Abundance season: September to January

PROCESSING

In order to guarantee the quality of our algae, they are carefully cleaned immediately after harvesting to remove any by-catch and return it to the ocean. Afterwards, they are taken to our facilities to be processed through one of the following drying methods.

technics:

FREEZE-DRYED

Frozen biomass processed using the freeze-drying technique, which consists in the extraction of water through sublimation, ensuring biomass preservation and increased shelf life.

SUN DRIED

Drying in the sun is carried out in greenhouses and is the most common method of processing, ensuring a relatively quick and sustainable dehydration, since it uses 100% clean energy.

DRIED IN THE DARK

Using 100% renewable heat energy, drying is carried out in a single continuous cycle, allowing the preservation of all organoleptic properties and sunlight-degradable compounds.

FORMATO:

Once dried in the sun or in the dark, the customer can also choose to receive their biomass in its natural form (whole) or grinded in different granulometries.

Whole

Grinded
