Abstract

This study proposes a method for extracting tannins from mangosteen peel for use in inducing digestion in aquatic animals. The extraction of tannins from mangosteen peel and their application in reducing ammonia levels in aquaculture, particularly for animals with high ammonia content, is investigated. The study compares fermentation and boiling methods using different quantities of mangosteen peel and extraction times without solvents. The effectiveness of the extract in reducing ammonia levels in water is then tested to determine its suitability for safe aquaculture practices.

------12/07/2566------(OCR) 1. The process for extracting tannin from mangosteen peel for inducing digestion in aquatic animals is as follows: a. Wash the mangosteen peel thoroughly with water and dry it in an oven until the final moisture content does not exceed 8%. b. Then reduce the size of the dried mangosteen peel into small pieces and grind them. c. Using a ratio of 0.1-0.5 parts of mangosteen peel to 10 parts of water. d. Boil for 60-180 minutes or soak in water according to ratio c for 20-60 days. 2. The process for extracting tannin from mangosteen peel for inducing digestion in aquatic animals, according to claim 1, where extraction by boiling yields the highest amount of tannin at a ratio of 0.3 parts of ground mangosteen peel to 10 parts of water, boiling time of 120 minutes. 3. The process for extracting tannin from mangosteen peel for inducing digestion in aquatic animals, according to claim 1. 1. Extraction by fermentation yields the highest tannin content at a ratio of 0.3 parts crushed mangosteen peel to 10 parts water, on 35-40 days. 1. Extraction process of tannins from mangosteen peel for inducing digestion in aquatic animals. This invention incorporates two solvent-free extraction methods: Method 1: Boiling extraction, with the following steps: a. Wash the mangosteen peel thoroughly and dry it to a final moisture content of no more than 8%. b. Reduce the size of the dried mangosteen peel to small pieces and then grind it. c. Weigh the mangosteen peel at a ratio of 0.1-0.5 parts to 10 parts water and boil for 60-180 minutes. Method 2: Fermentation extraction, with the following steps: a. Wash the mangosteen peel thoroughly and dry it to a final moisture content of no more than 8%. b. Reduce the size of the dried mangosteen peel to small pieces and then grind it finely. c. Weigh the mangosteen peel at a ratio of 0.1-0.5 parts to 10 parts water. d. Soak the finely ground mangosteen peel in the ratio specified in step c for 20-60 days. 2. The process for extracting tannins from mangosteen peel for use in inducing digestion in aquatic animals, according to Patent 1, where extraction by boiling yields the highest amount of tannins at a ratio of 0.3 parts crushed mangosteen peel : 10 parts water for a boiling time of 120 minutes. 3. The process of extracting tannins from mangosteen peel for use in inducing digestion in aquatic animals, according to Patent 1, where extraction by fermentation yields the highest amount of tannins at a ratio of 0.3 parts crushed mangosteen peel : 10 parts water on day 35 onwards. 4. For optimal application in aquaculture ponds, use 15 liters per rai, or adjust the amount of ammonia to be reduced by using 13 ppm of tannin extract for a 1 ppm ammonia reduction.
