Microalgae innovator Brevel Ltd., introduces Purallis, a clean-label chlorella for nutraceuticals that is cultivated in a closed system indoors. The company produces standardised chlorella using its proprietary illuminated fermentation biomanufacturing platform. This will allow high yields and solve some of the bottlenecks of sourcing chlorella that comply with consumers’ expectations of purity and standardisation.
Chlorella is traditionally grown in freshwater ponds and requires sunlight to generate its nutrients and vibrant green colour. Some 90% of the global chlorella supply is pond grown, with the remainder shifted to closed fermentation systems (mostly in Europe). Chlorella is a known bioaccumulator, binding to pollutants and heavy metals present in surrounding water and air. As a result, cultivation must take place in clean, controlled environments with routine testing for heavy metals, pesticides, and microbial contaminants to help ensure product safety and quality.
Yonatan Golan, co-founder and CEO of Brevel, said, “The strict requirements for purity, consistency, and safety have tended to strain supply of this ingredient. Our illuminated fermentation platform is instrumental in helping ease the strain on the supply of ultra-pure, highly nutritious chlorella in a consistent manner.”
It pioneered proprietary technology that combines light with fermentation in a closed, sterile system. This innovative platform enables the production of high-quality chlorella microalgae in generous quantities. Fermentation, traditionally limited to dark environments, is responsible for producing microalgae at very high yields. It is the first company to unite the two processes and bring fermentation out of the dark.
The company adapted its platform to grow chlorella in response to flourishing market demands for this popular nutritional source and realisation of its potential as a cornerstone ingredient in the future of food, wellness, and cosmeceuticals.
Yfah Burstin, chief business officer for Brevel, said, “Our clean-label Purallis chlorella is cultivated in fully controlled, sterile bioreactors, eliminating any risk of contaminants or heavy metals. Thanks to the integrated light, it delivers premium chlorella that is exceptionally rich in complete protein, antioxidants, and chlorophyll. Moreover, the concentrated light extends nutrient density and functionality, while delivering a very mild flavour. For example, it can adjust iron levels for optimised formulations.”
Chlorella has a thick, rigid cell wall composed of complex polysaccharides (cellulose and sporopollenin). This wall is indigestible, so it uses a bead mill to physically break the algae cells and open and release the contents of the cells into the liquid matrix in a simple, mechanical way. The process omits the need for harsh chemicals or high temperatures.
The global chlorella market is experiencing strong momentum, largely propelled by a global shift toward natural, plant-based and sustainable health products. Currently valued at approximately $328 million, projections indicate it could reach $486 million by the early 2030s. Recent scientific research points to renewed interest in the green microalgae owing to its extensive biochemical makeup which has been linked to antioxidant, anti-inflammatory, detoxifying and nutritive capabilities as well as a supportive role in metabolic function.
Chlorella (Chlorella vulgaris) is a renowned superfood carrying an impressive nutritional profile. This nutrient-dense microorganism is a treasure trove of protein, micronutrients, and antioxidants. In fact, chlorella is composed of 50% protein and boasts the complete spectrum of amino acids, alongside naturally occurring vitamins (notably B vitamins), omega-3 fatty acids, essential minerals, and fibre. It is uniquely rich in iron and contains beneficial bioactive compounds including carotenoids, chlorophyll, and polyphenols—key compounds that protect against oxidative stress and support body detoxification.
“Chlorella is a highly versatile and sustainable ingredient with relevance to various wellness categories. Recent research revealed that in some persons, chlorella can function as a ‘precision prebiotic’ that could help correct specific microbial imbalances via powerful polysaccharide compounds, supporting beneficial bacteria that keep the gut lining healthy. It also could serve as a strategic nutritional tool for filling protein and nutrient gaps in GLP-1 and other reduced-calorie diets where users must be sure they are getting more from every bite they consume. We call it GLP-1 friendly food,” concluded Burstin.
