Cell grown Oocytes

Caviar‘ is a luxury foodstuff that is traditionally composed from the unfertilised eggs, technically known as oocytes, of Sturgeon fish.

Clean’ is a Cellular Agriculture (foodstuff grown from cells versus live animals) term that is applicable to products that boast beneficial features such as better sustainability,  reduced carbon footprint, free from antibiotics and chemicals, or intensive farming operation with comprised standards of moral farming husbandry.

Recently ‘Clean’, ‘animal-free’ foods have gained increasing attention and consumer interest is predicted to keep growing as market trends evolve.

‘Clean foods’ are produced by two major routes – plant based and cell-based. The Cell-based approach employees bioprocessing facilities to produce typically animal-derived foods, such as meat and dairy products, by using cultivated cells. This cruelty-free method of food production avoids the exploitation of animals for food.

The Sturgeon fish is a living fossil, with a lifespan (in some subspecies) of > 150 years. The sturgeon’s existence dates from ~ 300m years ago, and therefore it predates nearly all members of the animal kingdom. Today, the Sturgeon fish is mainly revered for its prized roe, commonly known as ‘Caviar’.

Global demand for ‘Caviar’ is expected to rise to 3000tns a year by 2050, which raises the question as to how best this growth demand can be met, and whether or not a ‘clean caviar’ product option could be explored, paving the path for a more ethical, moral and sustainably farming production process.

With this in mind, Caviar Biotec has now brought together leading disciplines from the emerging ‘Clean’ cellag farming industry, and has developed a feasible R&D program to pioneer the ability to grow Caviar outside of the sturgeon fish.

In 2021, Caviar Biotec will continue investigation into bioengineering of sturgeon tissue and bio-synthesizing of sturgeon oocyte, for the purpose and production of two ‘clean caviar’ products: a Cell and Animal-free Caviar Analogue (CAFCA), and a cell-based Cellag caviar product – Cellviar.
