In this study, Alyssum homolocarpum (AH) and Lepidium sativum seed gum (LS) at different ratios 1:0, 1:1, and 0:1 utilized to encapsulate red onion extract (ROE) for beef coating through immersion. Different concentrations of ROE (400, 800, 1200 and 1600 ppm) showed high antioxidant activity due to phenolic and flavonoid compounds. In terms of mean size, the lowest particle size was observed in ROE encapsulated in Alyssum homolocarpum gum (7.4 3 89.3 nm). And nanoemulsions prepared in Lepidium sativum seed gum had higher particle size (145.7 3 2.3 nm). Negative-zeta potential was observed in all nanoemulsions. Meat samples were kept at 4 ° C for 20 days and the values ​​of thiobarbituric acid, color indices L *, a *, b *, total bacterial count were examined at 4-day intervals. The results showed that ROE encapsulated in LS and AH was more effective in delaying the microbial and chemical reactions of coated meat fillets. Due to reduced bacterial growth, decreased thiobarbituric number and microbial growth, shelf life increased from 4 days to 16 days. This study confirmed that ROE encapsulated in the combined coating of AH and LS is a potential coating to improve the quality and shelf life of beef fillets.
