Application of epigenetics for allergen-free peanut production: a comprehensive review

Epigenetic methods provide a promising avenue for creating allergen-free peanuts, helping to address the increasing incidence of peanut allergies and related health issues globally. This paper thoroughly explores epigenetic approaches for producing allergen-free peanuts and offers new possibilities for effectively managing peanut allergies. By specifically targeting genes like Arah1, Arah2, and Arah3, the major allergens responsible for allergic reactions can be reduced. Innovative technologies such as CRISPR/dCas9 and RNA interference enable precise regulation of gene activity, facilitating allergen-free peanut production without altering the underlying DNA sequence. The advantages of allergen-free peanuts extend beyond the health benefits, as they have the potential to enhance food safety and open up entirely new markets for peanut-based products. These peanuts could be safely reintroduced into public spaces, like schools and daycare centers, increasing consumer trust and fulfilling the growing demand for safe, nutritious alternatives. However, challenges persist, such as ensuring stable epigenetic changes, preserving other essential peanut traits, and understanding their long-term effects on human health and the environment. Ongoing research should focus on refining these techniques to address these challenges, promote the successful integration of allergen-free peanuts into agricultural systems, and improve public health while transforming the food industry in a sustainable manner.
