Mangosteen pericarps have active compound is xanthone that serves as an antioxidant. It can made into caviar with spherification techniques. The purpose of this research is to know the characteristics of pericarp and mangosteen pericarp extract, to know about change of sol and caviar chemical composition, to get the best formula caviar, and to get financial analysis efforts caviar. The main raw materials that used are mangosteen pericarp, sodium alginate, calcium chloride, apple vinegar, and water. The characteristics of mangosteen pericarp with water content is 61.90%, protein content is 3.48%, materials content is 1.18%, fiber content is 22.93%, total acid is 4 ml NaOH 0.1 N/g mangosteen pericarp, xanthone content is 1.18 mg/g mangosteen pericarp, and tannin content is 4.55%. The characteristics of mangosteen pericarp extract with xanthone content is 0.87 mg/g mangosteen pericarp extract, tannin content is 3.79%, fiber content is 0.88%, and total acid is 7.76 ml NaOH 0.1 N/g mangosteen pericarp extract. The characteristic sol results obtained range of values xanthone is 0.78-0.85 mg/g sol, the range of the values of tannin is 3.69-3.78%, the range values of fiber content is 12.29-14.21%, and range values of total acid is 3.18-3.98 ml NaOH 0.1 N/g sol. The characteristic caviar results obtained range of values xanthone is 0.76-0.81 mg/g caviar, the range of the value of tannin 3.24-3.75 %, the range of fiber content is 11.06-14.11 %, and range values of total acid is 0.88-1.84 ml NaOH 0.1 N/g caviar. The best formula is A3B2 with xanthone content is 0.81 mg/g caviar, tannin content is 3.75%, fiber content is 13.17%, and total acid is 1.12 ml NaOH 0.1 N/g caviar. Total production cost of cocktail effort is Rp.172 010.91.
