1. A manufacturing method of an astaxanthin (AST) nanoemulsion, comprising steps of:
(a) adding an AST material into a peanut oil and mixing them uniformly to obtain an AST oil mixture;
(b) adding 0.25-1.5 (w/w) % of D-α-tocopherol polyethylene glycol succinate (TPGS) into the AST oil mixture and mixing them uniformly to obtain a mixed solution;
(c) adding water into the mixed solution to obtain an AST nanoemulsion precursor; and
(d) shaking the AST nanoemulsion precursor to obtain the AST nanoemulsion.
