Given the outstanding impact of 'Novel Trends in Cultivated Meat Research’, Frontiers in Nutrition is happy to launch Volume II of this successful Research Topic.

Cultured or cultivated meat, also known as lab-grown or in vitro meat, is a type of alternative meat produced by utilizing principles of cell biology, molecular biology, tissue engineering and bioprocessing techniques. Cultivated meat is created by obtaining cells from an animal, such as a chicken, and culturing them in a laboratory environment to fabricate edible alternative meat products.

According to its promoters, the aim of cultured meat is to offer a sustainable alternative to meat, highlighting the negative impacts of traditional livestock farming. Controversies about the beneficial effects of these new products remain, however, and deserve to be investigated, as well as the nutritional value of cultured meat products.

While cultured meat is still in the early stages of development and not yet widely available to consumers worldwide, it has gained attention and investment from around the world. There are ongoing efforts to improve the technology and bring it to market.

However, major technical challenges associated with cultured meat research include development of novel cultured meat cell lines, edible scaffolds materials for growing cultured meat cells, bioprocess challenges, and end product development.

Despite cultured meat has been gaining traction in recent years, the market is still facing a challenge of neophobia, that is the fear of trying new products and it can have a significant impact on product allocation in the market. When it comes to cultured meat, neophobia can be a major obstacle to its adoption. Consumers may be hesitant to try something that is unfamiliar or perceived as artificial or unnatural. To overcome this fear, science must focus on creating positive associations with cultured meat and educating consumers about its benefits. Additionally, product allocation strategies should be adjusted to ensure that consumers are exposed to cultured meat in an effort to reduce their neophobia.
