And have been successfully cultivated, as they are currently the main source of agar (approximately 65 per cent). Gracilaria cultivation has thrived especially in Chile, but there are species of this algae, both wild and cultivated in Argentina, South Africa, Japan, Indonesia, the Philippines, China and India.
The demand for Gelidium is always high, so when it is possible to collect it, it is the main supplying countries Spain, Portugal, Marruecos, the Japan, Republic of Korea, China, Chile and South Africa. Other secondary sources of raw material for the production of agar in the species of Pterocladia (a small alga similar to Gelidium, which is collected in Azores and New Zealand) and Gelidiella (India, Egypt and Madagascar).
Annually 55 000 tonnes (dry weight) of seaweed
are extracted with 7 500 tonnes of agar produced for a value of US $ 132 million Chile, Spain and Japan produce 60% of the total production. agar. There are 30 known producers and it is estimated that there could be another 20 smaller producers. The development of new applications is slow and the growth rate of the agar industry is estimated to be around one percent for many years, very similar to the last thirty years. 3.5 Red algae as a source of carrageenanThe pearl moss (Chondrus crispus) was the original source of carrageenan, and until the end of the 1960s the availability of wild sources of this seaweed, which is best in cold waters, such as the coasts of Ireland and New Scotland,
limited the expansion of this industry. The cultivation of Chondrus in tanks turned out to be too expensive, but since the 1970s they have grown with great success in other warm water species, such as Kappaphycus alvarezii (also called cottonii) and Eucheuma denticulatum (spinosum), which are currently the main raw materials used to produce carrageenan.
The cultivation of these latest species
Benefits of seaweed Regular consumption of seaweed will benefit the health of the whole family: They are absolutely remineralizing, which directly affects the health of people and the general biochemical functionality of the organism.Stimulate the functioning of the thyroid gland and therefore metabolism. People with thyroid problems (especially hyperthyroidism) should avoid their consumption altogether.They are very alkalizing, which helps to compensate for the acidity caused by excess consumption of meat or processed foods.
began in the Philippines, but has since extended to other warm water countries with low labor costs, between Indonesia and the United Republic of Tanzania (Zanzíbar). The companies that dedicate themselves to the extraction of carrageenan are actively promoting cultivation in other areas, such as India, Africa and the islands of the Pacific.
- These species currently represent the 85 per cent of raw materials used by the industry, whereas Chondrus (from Canada,
- France, Spain, Portugal and the Republic of Korea) represents the five per cent of Gigartina species from Chile , Marruecos y México, represent the 10 per cent
- remaining. The total consumption of raw materials amounts to 150,000
tonnes of seaweed (dry weight), of which 28,000 tonnes of carrageenan are obtained for a value of 270 million US dollars. Hay 24 recognized producers of carrageenan and maybe another 10 smaller producers. However, 65 per total production corresponds to three companies. The producers are striving to promote new applications and annual growth in the last 15 years has been located in one eye for approximately.
It is estimated that in the next five years the annual growth will be approximately five per cent. 3.6 Other uses of seaweedSeaweed has been used since time as additives for pigs, especially in coastal areas where it is easy to transport fresh or partially dried seaweed to the area to be fertilized. The seaweed acts as a conditioning agent for its high fiber content and as a fertilizer for its mineral content.
Large brown algae
(species of Laminaria and Ascophyllum in Europe, Sargassum in warmer countries like the Philippines) are misused, but the appearance of synthetic chemical fertilizers has been reduced in the market. More recently, if liquid seaweed extracts have been marketed that apply to less expensive crops, such as vegetables and bayas;
- if you can get faster and faster growth producers, depending on these results with the presence of vegetable hormone extracts similar to auxin. In South Africa each 500
- tonnes of fresh Ecklonia are used to obtain these extracts, but in the United Kingdom and New Zealand similar products are also obtained from other
- brown algae. The seaweed Ascophyllum nodosum abounds in the coldest waters of Ireland, Scotland, Norway and New Scotland.
It is used in part for alginate production, but an industry based on its application has also been created as an additive for piensos. Dry seaweed if you can get a fine octopus that is sold as harina. Take advantage of the artificial desiccation, because the production costs fluctuate in the crude oil cost and because the market can only support certain costs, the production varies over the course of the years.
Currently, it is estimated at 1 000 tonnes of dry weight a year, with a value of five million US dollars.Hello everyone, This week we are going to treat the main types of seaweed, their uses and their properties in the diet. It is a food that, as verels, continuation should be basic to consume because it provides a multitude of benefits.
Seaweed provides minerals, vitamins, stimulates metabolism and purifies us from the inside. Do you know how to use them? We explain this to you in this article. There are several studies that show that in the areas where more algae is consumed, people live longer and in a healthier way. And it is not surprising, I think that the nutritional richness of seaweed can become more than twenty times that of any other vegetable.
