Abstract

Summary of the Invention: This invention describes a method for extracting dietary fiber from banana peels to obtain water-soluble dietary fiber. The process involves preparing banana peels by wet grinding, removing fat, starch, and protein, then hydrolyzing with sodium bicarbonate. The peels are then washed, dried, blended, and filtered to obtain both water-soluble and insoluble dietary fiber. The aim is to develop a simple and straightforward extraction method for banana peel dietary fiber, yielding a powder containing both water-soluble and insoluble fibers. This extract offers health benefits, including the potential for use in beverages or dietary fiber supplements for improved digestion and overall health. Furthermore, it has the potential for commercial value and development.

Claims (6)

Claims 1. The process of extracting dietary fiber from banana peels to obtain water-soluble dietary fiber involves the following steps: a. Prepare ripe banana peels (grade 6-8), wash them thoroughly, and wet grind them using a 5-speed blender at a ratio of banana peel to water of 1:20 by weight. Filter to separate the pulp, wash with hot water at 80-100 degrees Celsius for 5-10 minutes, filter again, and then dry in a tray dryer at 50-60 degrees Celsius until the moisture content does not exceed 12 percent. b. Soak the dried banana peels in a 95% ethanol solution at a 50:50 ratio by volume to weight to remove fat for 24-48 hours at room temperature. Then filter through cheesecloth, squeeze out the solution, and dry in an oven at 65 degrees Celsius for 24-48 hours. c. Take the de-fat-removed banana peels... Starch removal was performed using alpha-amylase enzyme at a concentration of 1% w/v. 15 banana peels were heated to 95°C for 30-60 minutes. The pH was then adjusted to 4-4.5 using hydrochloric acid solution. The solid residue was filtered and dried in a hot air oven at 50-60°C for 24-48 hours. The defabricated and starch-removed banana peel powder was then protein-removed using neutrace enzyme. Distilled water was added to the banana peels in a ratio of 1:20. The JH 20 was adjusted to 7.5 using sodium hydroxide solution. Finally, 1.0% w/v neutrace enzyme was added. The banana peels were heated to 60°C for 30-60 minutes. The resulting solution was filtered, separating the pulp. This pulp was then dried in a hot air oven at 60°C for 24-48 hours. The dried banana peel fiber powder was then hydrolyzed with 2.0% sodium bicarbonate (weight/volume) for 1-2 hours to further break down the fiber and improve its solubility and digestibility. Afterwards, it was further dried at 50-60°C for 24-48 hours. The resulting powder was finely ground and sieved through a 60-mesh screen, yielding a fine, water-soluble banana peel fiber powder. 2. The process for extracting dietary fiber from banana peels to obtain water-soluble dietary fiber, as per Clause 5, Patent 1, where the appropriate amount of banana peel used is 5 percent by weight of the peel of Cavendish bananas. 3. A method for extracting dietary fiber from banana peels to obtain water-soluble dietary fiber according to Patent 1 or 2, where an optimal amount of 95% ethanol solution is used at 50% by weight of 10 saplings of banana peel. 4. A method for extracting dietary fiber from banana peels to obtain water-soluble dietary fiber, according to any one of Patents 1-3, where the enzyme alpha-amylase is used in an appropriate amount of 1 percent by weight of the banana peel. 5. A method for extracting dietary fiber from banana peels to obtain water-soluble dietary fiber, according to any one of Patents 1-4, where the enzyme nutraceutical is used in an appropriate amount of 151 percent by weight of the banana peel. 6. A method for extracting dietary fiber from banana peels to obtain soluble dietary fiber, according to any one of Patents 1-5, where the appropriate amount of sodium bicarbonate is used at 2 percent by weight of the banana peel.
