Anthocyanins are a type of flavonoid,
a class of compounds with antioxidant effects, found in high quantities in various fruits and vegetables.
They are water-soluble pigments that may appear red, purple, or blue depending on the pH.
They belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway.
These pigments are found in the cell vacuole, mainly in flowers and fruits, but also in leaves, stems, and roots.
The primary role of anthocyanins in plants is attracting pollinators and seed dispersers.
However, they also contribute to a plant's defenses against various stresses such as cold, drought, and disease.
For humans, anthocyanins are notable for their potential health benefits. They are potent antioxidants,
protecting the body's cells from damage by free radicals. Some research suggests that they may offer anti-inflammatory,
anti-viral, and anti-cancer benefits. They may also aid in the prevention of cardiovascular disease and improve visual
and cognitive functions.
Anthocyanins are part of the reason fruits and vegetables with deep red, purple, and blue colours are often associated with health-promoting properties.
Examples of some flowers containing anthocyanins are listed below:
Roses -
Many varieties of roses contain anthocyanins, giving them colours ranging from pink to deep red and purple..
Pansies - These flowers exhibit a wide variety of colours due to anthocyanins,
including many shades of purple and blue.
Petunias - The purple and blue hues of many petunias are a result of anthocyanins.
Hydrangeas - In some varieties of hydrangeas, the colour of the flowers
can be changed by adjusting the pH level of the soil, which in turn affects the colour of the anthocyanins.
Tulips - Some tulips have deep purple, pink, or red hues due to
the presence of anthocyanins.
Delphiniums - The stunning blue colour of delphiniums is due to anthocyanins.
Examples of some seeds containing anthocyanins are listed below:
Chia Seeds -
Black chia seeds contain a certain amount of anthocyanins, primarily cyanidin and delphinidin derivatives, which contribute to their dark coluor.
Black Soybean - Black soybean seeds have anthocyanins in their seed coat, primarily
cyanidin-3-glucoside, delphinidin-3-glucoside, and peonidin-3-glucoside.
Grape Seeds (from dark grapes) - Grape seeds from dark-coloured grapes
contain several anthocyanins, including malvidin, peonidin, and cyanidin.
Black Sesame Seeds - Black sesame seeds have anthocyanins,
specifically cyanidin-3-glucoside, that contribute to their black colour.
The extraction process, including the solvents and methods used, can influence the concentration and types of anthocyanins present in the final extract.
It is often the case that a balance needs to be found between fully-extracting all anthocyanins while also ensuring that the compounds that are
obtained are of a high quality and not degraded.
At Celignis we have extensive experience in the design and optimisation of extraction protocols for a wide variety of chemical constituents from
many different biomass types. If needed we can also work on processes to separate and purify the target compounds.

Celignis is a Partner in 3 Successful Proposals for EU Funding
We are pleased to announce that three of the proposals involving Celignis, submitted to the CBE-JU programme for funding collaborative biomass research in Europe, were successful. These projects will provide an additional funding of €1.5m to Celignis and build on our achievements in other CBE and EU projects. In particular, the projects are all at enhanced TRLs (6/7) and will use our existing Celignis Bioprocess infrastructure and will also fund further development of our bioprocessing capacities and the Bioprocess Development Services we offer our clients.
Details on the funded projects are provided below:
BIONEER - This project was funded under CBE-JU topic IA-06 and focuses on the TRL 6/7 production of biobased platform chemicals. Celignis's activities in the project focus on scaling up the work undertaken in our ongoing
Celignis to Exhibit and Present at Major Biochar Event
The 2024 North American Biochar Conference will take place in Sacramento, California, on Feb 12-15
On Feb 12-15 we'll be exhibiting at the 2024 North American Biochar Conference, taking place at the SAFE Credit Union Convention Centre in Sacramento, California.
We're looking forward to interacting with the 1000+ expected attendees, outlining our extensive range of analytical and application testing services for biochar.
Celignis CIO Lalitha Gottumukkala will also be a member of the expert panel focused on developing improved laboratory methods for biochar characterisation.
This Networking Event Will Involve Discussions on Collaborations for Proposals to the 2024 CBE-JU Topics
The Circular Bioeconomy Europe Joint Undertaking (CBE-JU) is an organisation that funds biomass research in Europe at various Technology Readiness Levels (TRLs). Since 2016 Celignis has been an active participant in a number of projects funded by the CBE-JU.
The Biobased Industries Consortium (BIC) is the steering committee that helps to steer the focus of research for the CBE-JU programme. In 2023 Celignis joined the BIC as a Full Industry Member and participated in several proposals submitted for different research topics in the CBE-JU's 2023 Work Programme.
We're Hiring - Business Administration & Client Relationship Manager

Situated in Limerick, Ireland, Celignis currently operates at two centres, Celignis Analytical and Celignis Bioprocess, actively engaging in a variety of private and public bioeconomy projects. As we continue to expand, we're looking to strengthen our team of 14 with a Business Administration and Client Relationship Manager who can bring a blend of enthusiasm and expertise.
This position will involve working closely with senior management, fostering existing and new client relationships, and ensuring successful delivery of our services, playing a key role in our ongoing growth and success.
Celignis to Sponsor and Present at Major Biochar Event
The event takes place on May 3rd at Carrick-on-Shannon
We are pleased to announce that, on May 3rd, Celignis will be presenting and exhibiting at the National Biochar and Carbon Products Conference 2023, which is taking place in Carrick-on-Shannon in County Leitrm, Ireland.
This conference is being organised under the auspices of the Interreg Northwest Europe-funded THREE C Project, entitled 'Creating and sustaining Charcoal value chains to promote a Circular Carbon economy in NWE Europe'.
The conference will highlight both Irish stakeholders who are currently working in the biochar and carbon products sector, but also partners from the THREE C project (covering Netherlands, Luxembourg, Germany, Belgium, France and Wales, as well as Ireland) who have interesting stories and products to share.
