Process of producing beverage by fermenting cactus fruit and pitaya

Abstract

A process of producing beverage includes washing and drying cactus fruit and pitaya; juicing the cactus fruit to obtain juice of the cactus fruit and juicing the pitaya to obtain juice of the pitaya respectively; filtering the juice of the cactus fruit and the juice of the pitaya respectively; mixing the filtered juice of the cactus fruit and the filtered juice of the pitaya with water to obtain a solution; pouring yeast and gram-positive bacteria in the solution wherein the yeast is saccharomyces boulardii and the gram-positive bacteria includes lactobacillus acidophilus and bifidobacterium longum; and fermenting the solution until beverage is produced wherein fermentation temperature is between 26 C. and 35 C. and fermentation time lasts for 3 to 10 days.

Claims

DETAILED DESCRIPTION OF THE INVENTION

[0010] Referring to FIG. 1, a process of producing beverage by fermenting cactus fruit and pitaya in accordance with the invention illustrated. The process comprises the following steps: [0011] Step 1: Washing cactus fruit and pitaya with clean water. [0012] Step 2: Drying the clean cactus fruit and pitaya to remove water out of peels of both cactus fruit and pitaya. [0013] Step 3: Juicing the cactus fruit to obtain juice of the cactus fruit and juicing the pitaya to obtain juice of the pitaya respectively. [0014] Step 4: Filtering the juice of the cactus fruit and the juice of the pitaya respectively. [0015] Step 5: Mixing the filtered juice of the cactus fruit and the filtered juice of the pitaya with water to obtain a solution wherein a volumetric ratio of the filtered juice of the cactus fruit, the filtered juice of the pitaya, and water is 0.05-0.1:1-5:1-5. [0016] Step 6: Pouring yeast and gram-positive bacteria in the solution wherein the yeast is saccharomyces boulardii, the gram-positive bacteria includes lactobacillus acidophilus and bifidobacterium longum, and a volumetric ratio of saccharomyces boulardii, lactobacillus acidophilus, and bifidobacterium longum is 1-5:1-3:1-3. [0017] Step 7: Placing the solution in a fermentation tank for fermentation until beverage is produced wherein fermentation temperature is between 26 C. and 35 C., and fermentation time lasts for 3 to 10 days.

[0018] The sugar free fermentation saves time and the beverage has a lower calorie.

[0019] Referring to FIGS. 2 and 3, advantages of the process of the invention are shown in which FIG. 2 is a chart of days versus values for anti free-radical DPPH (2,2-diphenyl-1-picrylhydrazyl) activity before and after fermentation, and FIG. 3 is a bar chart of days versus values for anti free-radical DPPH activity before and after fermentation. Specifically, the solution before fermentation (called the solution) is compared with the beverage produced by fermentation (called the beverage) in a daily basis.

[0020] As shown in FIG. 2 specifically, in day 1, there is no difference between the solution and the beverage in terms of anti free-radical DPPH activity; in day 2, the anti free-radical DPPH activity of the beverage is greater than that of the solution; in each of days 3, 4, 5 and 6, the anti free-radical DPPH activity of the beverage is significantly greater than that of the solution as the day proceeds; and in days 7 and 8, the anti free-radical DPPH activity of the beverage is substantially no change in comparison with that of the beverage observed in day 6.

[0021] It is concluded that the anti free-radical DPPH activity of the beverage is significantly greater than that of the solution.

[0022] As shown in FIG. 3 specifically, the anti free-radical DPPH activity of the beverage is about two times of that of the solution.

[0023] The invention has the following characteristics: The beverage is antioxidant. Saccharomyces boulardii, lactobacillus acidophilus, and bifidobacterium longum do not exclude one another and may greatly increase anti free-radical DPPH activity of the production of the beverage. The beverage is full of nutrients. Fermentation time is greatly decreased. No sugar is added in the process. Calorie of the beverage is greatly lowered.

[0024] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
