The present study was conducted with the objective of studying the genetic diversity of essential oils (EOs) in curry leaf (CL) ex-situ. Chemometric methods and pattern analysis were employed to assess the genetic diversity of EOs and to characterise diverse sets of CL germplasm into different chemotypes. The study revealed a huge genetic diversity for EO yield and its composition among the tested genotypes. Cultivated types had significantly higher EO yields and showed a greater degree of genetic divergence compared to wild types. In total, 80 different compounds were identified in the EOs of CL and classified into major (6) and minor (74) compounds. The major compounds α-pinene, γ-terpinene, and α-selinene and 14 minor compounds were highly variable among the tested genotypes. They may play an important role in the formation of different chemotypes. Other important compounds, such as trans-caryophyllene and α-humulene, were more widely distributed among the tested genotypes and indicated their predominant occurrence in the EOs of CL. Some major compounds, such as valencene and γ-terpinene, showed a significant regional correlation, indicating the role of geographic factors in the evolution of different chemotypes. Furthermore, some compounds such as α-pinene, bornyl acetate, and camphene had significantly higher concentrations in wild types compared to cultivated types, indicating the influence of domestication through human selection on the composition of EOs in CL. A total of 4 major chemotypes were characterised, of which three new chemotypes are being reported for the first time in CL.

This review delves into using natural antimicrobials in the dairy industry and examines various sources of these compounds, including microbial, plant, and animal sources. It discusses the mechanisms by which they inhibit microbial growth, for example, by binding to the cell wall’s precursor molecule of the target microorganism, consequently inhibiting its biosynthesis, and interfering in the molecule transport mechanism, leading to cell death. In general, they prove to be effective against the main pathogens and spoilage found in food, such as Escherichia coli, Staphylococcus aureus, Bacillus spp., Salmonella spp., mold, and yeast. Moreover, this review explores encapsulation technology as a promising approach for increasing the viability of natural antimicrobials against unfavorable conditions such as pH, temperature, and oxygen exposure. Finally, this review examines the benefits and challenges of using natural antimicrobials in dairy products. While natural antimicrobials offer several advantages, including improved safety, quality, and sensory properties of dairy products, it is crucial to be aware of the challenges associated with their use, such as potential allergenicity, regulatory requirements, and consumer perception. This review concludes by emphasizing the need for further research to identify and develop effective and safe natural antimicrobials for the dairy industry to ensure the quality and safety of dairy products for consumers.
