In this study, basil seed gum (BSG) alone, and in combination with sesame protein isolate (SPI) were used in ratios 1:0 and 1:1 in order to encapsulate corn tassel extract (CTE) using the response surface method in the central composite design template was used. Also, the quadratic equation was used to optimize and investigate the effect of the concentration of corn tassel extract and homogenization time on the response of particle size and efficiency. At first, total phenolic content (TPC), antioxidant activity and antibacterial activity of corn tassel extract were investigated. In addition, the measured antioxidant activity (DPPH&FRAP) showed a very high potential of these compounds (FRAP=288.11, DPPH=85.05) for encapsulation. The content of total phenol and flavonoids obtained from the test results were 1968.23 and 1346.20, respectively. The analysis results showed that the nanoparticles obtained from coating basil seed gum had the lowest particle size (494.4nm). Also, the highest coating efficiency (76.2%) belongs to the sample coated with basil seed gum. The value of zeta potential increased (+44.57) in the use of composite coating, and reached its highest value. During the storage of encapsulated Nano emulsion in the period of 0,3,7,15 and 21 days, the stability of nanoemulsions decreased with the passage of time, in such a way that, the highest stability related to encapsulated Nano extract in the combined coating (94.85 per day zero and 33.8 for day 21). The result of this study showed that nanoencapsulated of corn tassel extract with basil seed gum is more effective than the combined coating. But by checking other parameters (such as stability), It is suggested to use this gum in combination with other wall materials, including sesame protein isolates, to achieve the desired results.
