Abstract

Soluble green tea powder (SGTP) has the functional properties of antioxidation and antibacterial. In this paper, SGTP was used as the aqueous phase to prepare tea tree seed oil nanoemulsion by low energy method. The effect of SGTP on tea tree seed nanoemulsion was studied by measuring the average particle diameter and light transmittance. And the total antioxidant capacity and antibacterial ability of the tea tree seed oil nanoemulsion were also examined. The experimental results show that the SGTP can reduce the particle size of the tea tree seed oil nanoemulsion. With the increase of the content of SGTP, the antioxidant capacity of the tea tree seed oil nanoemulsion is gradually improved, and the ability to inhibit Escherichia coli and Staphylococcus aureus is further enhanced. Therefore, SGTP play a good role in the tea tree seed oil nanoemulsion, and may broaden its application in functional food, medical field and scientific research.
