TH14980U - A method for extracting beta-carotene from ripe palmyra fruit. - Google Patents

Abstract

Page 1 of 1. Summary of the Invention: The process of extracting beta-carotene from ripe palmyra palm fruit involves washing the ripe palmyra palm fruit thoroughly, peeling off the shiny black outer peel, and then crushing the dark yellow fibrous layer (middle peel) with clean water. The water is then separated, resulting in a yellow powdery sample. This sample is then extracted using an ethanol solution at an appropriate ratio, undergoing various processes, and the solvent is evaporated. This yields a crude extract that represents ripe palmyra palm fruit and can be used in any season. It retains a color and scent similar to ripe palmyra palm fruit, contains a high amount of beta-carotene, and can be stored at room temperature. The extraction of beta-carotene from ripe palmyra palm fruit pulp is intended for use as an active ingredient in cosmetics such as soaps or lotions. This not only adds value to the discarded natural material of ripe palmyra palm peel but also reduces environmental pollution. The extract from the palmyra palm fruit is a viscous, dark yellow liquid with a scent similar to ripe palmyra palm fruit.

------23/04/2561------(OCR) Page 1 of 1 page. Claims. 1. The process for extracting beta-carotene from ripe palmyra palm fruit involves the following steps: a. Preparation of the sample: Wash the ripe palmyra palm fruit thoroughly. Remove the outer black peel. Crush the middle peel, which is fibrous and dark yellow, with clean water. Filter the mixture to separate the water and pulp using cheesecloth. The resulting sample will be a fine, smooth, yellow powder. b. Extract the powder with a solvent, ethanol solution, in a ratio of 1:5 to 1:30 (w/v). Shake the mixture at 300-700 rpm at 30-50°C for 3-24 hours. Continue soaking in the ethanol solution for another 1-7 days. c. Filter the clear solution using filter paper. The remaining residue is then subjected to further extraction. Repeat the process with the same solvent, filter again, and combine the clear solutions from both times. Evaporate the ethanol solution to obtain the crude palmyra palm extract containing beta-carotene. 2. Method for extracting beta-carotene from ripe palmyra fruit according to claim 1, where the solvents used are ethanol, acetone, hexane, and petroleum ether. 1. The process of extracting beta-carotene from ripe palmyra palm fruit involves the following steps: a. Preparation of the sample: Wash the ripe palmyra palm fruit thoroughly. Remove the outer black peel. Crush the middle peel, which is fibrous and dark yellow, with clean water. Filter to separate the water and pulp using cheesecloth. The resulting sample will be a fine, smooth, yellow powder. b. Extract the powder with an ethanol solution in a ratio of 1:5 to 1:30 (w/v). Shake the mixture at 300-700 rpm at 30-50°C for 3-24 hours. Continue soaking in the ethanol solution for another 1-7 days. c. Filter the clear solution using filter paper. Repeat the extraction of the remaining pulp with the same solvent. Filter again, and combine the clear solutions from both extractions. d. Evaporate the ethanol. This will yield a crude extract of the palmyra palm containing a significant amount of beta-carotene. 2. A method for extracting beta-carotene from ripe palmyra fruit, as per claim 1, where the solvents are ethanol, acetone, hexane, and petroleum ether.
