What are Euglena microalgae?

Our companion, Euglena.

Our company, Euglena Co., Ltd., upholds the philosophy of “Sustainability First.” We are making progress with research each day in our hope to change the future, which is full of many uncertainties, into something brighter through the power of Euglena microalgae.

Euglena is nutritious

Euglena, which has properties of both plants and animals, actually contains 59 varieties of nutrients that include vitamins, minerals, amino acids, and unsaturated fatty acids. It also contains an excellent balance of all nine types of essential amino acids for adults. We are not exaggerating when we say that Euglena contains most of the nutrients that humans need to live.

59 nutrients work in a team

Nutrients contained in 1 billion Euglena (about 1000 mg) on Ishigaki Island
There are so many other ingredients!

Dietary fiber, zinc, iron, niacin, β-carotene, vitamin B1, vitamin B2, vitamin B12, vitamin E, vitamin K

The presence of cell walls

Euglena, which has the characteristics of both plants and animals, boasts a high digestibility of 93.1% because it does not have a cell wall that interferes with absorption.

Vegetables: Vegetables have a hard cell wall and are difficult to absorb nutrients / Euglena: Since there is no cell wall that interferes with Kyushu, it is easy to digest and absorb nutrients (digestion rate 93.1%).

Euglena contains a large amount of paramylon, which is a special substance not found in any other living organism. This is a type of β-glucan often found in mushrooms and similar organisms.
Paramylon, which is a dietary fiber, is a noteworthy substance that is expected to have health applications and is being researched by many scientists and experts.

Euglena Co., Ltd.’s ideas about health

At Euglena Co., Ltd., we have focused on not one but a number of complex factors as the cause of health concerns in modern humans. In particular, insufficient nutrition, fatigue, and lowered immunity influence each other, and this leads to a chain-reaction in deteriorating physical health as shown in the diagram below.

Insufficient nutrition, fatigue, and lowered immunity influence each other


Euglena is sustainable

Reduction of environmental load by photosynthesis

Euglena grows and proliferates by photosynthesis. Performing photosynthesis means immobilizing carbon dioxide on carbohydrates to produce oxygen. Euglena is very superior in this production efficiency compared to other plants.

This high carbon dioxide fixing capacity is expected to be very promising for global warming countermeasures.
Euglena was the first in the world to succeed in edible outdoor mass culture of Euglena. Euglena and others are photosynthesizing in the Our culture pool today.

Obtained ASC-MSC seaweed (algae) certification for the first time in the world

Our acquired "ASC-MSC seaweed (algae) certification" for the first time in the world.
ASC certification is an international certification system for marine products produced by responsible aquaculture methods that are environmentally and socially friendly, and MSC certification is an international certification for marine products caught in sustainable and environmentally friendly fisheries. It's a system.

Our, grown in the beautiful nature of Ishigaki Island, Okinawa Prefecture, is a sustainable ingredient.

Contributing to solving nutritional problems in Bangladeshi children

In Bangladesh, half of children under the age of 5 are anemic, and vitamins A, B12, iron, zinc, etc. tend to be deficient, and 36% of children under the age of 5 or about 5.5 million are stunted. I have fallen into. Euglena aims to solve the nutritional problems of Bangladeshi children, and delivers nutritious Euglena cookies to Bangladeshi children as part of the sales from customers.


Contributes to regional development

Our is also useful for regional development.
In the "Euglena Ishigaki Nuchigusui Project", we are developing menus and foods using Ishigaki Island Euglena as a special product of the island so as to contribute to the further regional development of Okinawa with Ishigaki Island as the source.
In Akita Prefecture, we are contributing to industrial promotion by using the new material "Midori Jiuqu" developed by Akita Konno Shoten and Euglena Co., Ltd. "Midori Jiuqu", which is produced by mixing steamed domestic rice with seed koji and euglena, will contribute to regional revitalization as a new raw material that leads to the charm of "Akita, the country of beauty" known for its fermentation culture. ..

Euglena Trivia Knowledge Single-celled organism Euglena is also diverse

Euglena grows Euglena Gracilis on Ishigaki Island. Euglena, a unicellular organism, proliferates by repeating division, that is, the number of individuals with the same cell increases steadily, so at first glance it seems that "every Euglena is the same", but in fact, each Euglena has its own individuality. It will introduce a part of.

It is often used mainly in supplements and foods. It is characterized by containing a large amount of paramylon, which is a type of dietary fiber.
It has a very slender body among Euglena, and is characterized by its high ability to adapt to the environment.
San Guinea
Since it contains astaxanthin, which is a kind of carotenoid like lycopene, which is a red component of tomato, it turns bright red depending on the conditions.
Agilis most closely related to Gracilis. However, their properties are completely different, such as their small size and their inability to grow in acidic environments.

Further Possibilities of Euglena

The possibilities of Euglena are endless! It is used not only for foods, but also for fuels and feeds, as well as fertilizers and biomass plastics that use euglena residues. The future, which will be an integral part of our lives, is just around the corner.

Foods and supplements
Euglena has a well-balanced total of 59 types of nutrients, including 13 types of vitamins, 9 types of minerals, 19 types of amino acids, 12 types of unsaturated fatty acids such as DHA and EPA, and paramylon, which is a type of dietary fiber. It contains. However, Euglena was difficult to cultivate because it is located at the bottom of the food chain and is quickly preyed on by other organisms. Nevertheless, in 2005, Euglena finally succeeded in mass culturing, and now it has become a supporter of our health.
Biofuel business
ミドリムシは培養方法によって、体内により多くの油を作ることができます。この油を抽出・精製することで、バスや飛行機などに利用可能なバイオ燃料をつくりだすことができ、すでに日本各地でミドリムシを原料の一部にしたバイオディーゼル燃料を使ったバスや乗用車が公道走行しています。 ミドリムシは培養時に農地を必要としないため農作物や土地との競合性が低く、かつ、光合成で成長するので化石燃料を消費して排出されるCO2を吸収して育ち、炭素循環型社会を構築することができるのです。
Animal feed
We manufacture feed using Euglena, which contains 59 kinds of abundant nutrients. Studies have shown that the use of this feed improves taste and quality. In addition, by utilizing Euglena, the protein sources used in feed can be diversified, and Euglena, which does not compete with food, is also effective as a sustainable raw material.
The umami of the food you usually eat also has the power of Euglena.
Potting soil / fertilizer
Organic liquid fertilizers and potting compost that utilize the residue of Euglena from the biofuel manufacturing process, and organic chemical fertilizers that contain not only the residue but also Euglena are being developed.
It has been suggested that the use of Euglena may suppress the increase in yield and the decrease in crop freshness after harvesting, and research on further utilization and pursuit of functions in the agricultural field is being promoted in the future.
Biomass plastics
In addition to fertilizers, we are also working on the development of biomass plastics by utilizing the residues from the biofuel manufacturing process of Euglena. The development of "paramylon," a biomass plastic that uses paramylon, a unique ingredient contained only in Euglena, is underway, as well as those that utilize residues.
It has already been successfully developed, and experimental results show that it is stronger than 100% petroleum-derived plastic products. In addition, the development of biomass plastic will help solve social problems such as marine plastic waste, and will bring convenience to our lives while protecting the marine ecosystem.
