TH21879Y - A method for extracting pigments from plants using vegetable oil. - Google Patents

Abstract

------14/05/2020------(OCR) Page 1 of 1 Summary of Invention The method for extracting pigments from plants using vegetable oil, as described in this invention, consists of the following steps: Preparation of raw materials involves drying, freezing, or burning fresh or dried plant parts. The parts are then reduced in size and mixed with vegetable oil, continuously stirred, heated, and filtered to remove plant fragments. This yields pigments in the vegetable oil. This method can be further enhanced by removing water from the vegetable oil containing the pigments, resulting in pigments that can be used as coloring agents and antioxidants in food products such as emulsions, fats, and oils, as well as cosmetics. ------------ ------14/05/2020------(OCR) Page 1 of 1 Summary of Invention The method for extracting pigments from plants using vegetable oil, as described in this invention, consists of the following steps: Preparation of raw materials involves drying...

The mixture from step b is filtered using cheesecloth or a vacuum filter to remove plant parts, resulting in pigments in vegetable oil. 2. The process of extracting plant pigments using vegetable oil. 1. The process of extracting plant pigments using vegetable oil, under Reputation 1, where the selected plant part is the root, rhizome, seed, flower, fruit, bark, stem, or leaf, either individually or in combination with two others. 2.

The process of extracting plant pigments using vegetable oil, under Reputation 1 or 3, where the suitable plant oil is coconut oil. 4. The process of extracting plant pigments using vegetable oil, under Reputation 1, where the suitable heating temperature is 45°C. 5. The process of extracting plant pigments using vegetable oil, under Reputation 1, where the suitable heating time is 1 hour. 6. The process of extracting plant pigments using vegetable oil. According to Protection Clause 1, the optimal ratio of plant material to vegetable oil is 1:20 by weight. (Page 2 of 2, page 8) The process for extracting plant pigments using vegetable oil, according to Protection Clause 1, can be further enhanced by a dewatering step to obtain water-free pigments in the vegetable oil. This can be achieved by removing water from the pigments using at least one of the following methods: vacuum evaporation, vacuum drying, or separating the pigments using a separating funnel. 9. The process for extracting plant pigments using vegetable oil, according to Protection Clause 8, where the temperature for vacuum evaporation or vacuum drying is 30-60°C. 10. The resulting pigment product, according to any one of Protection Clauses 1 through 9, is liquid, clear, and has a color appropriate to the type of plant selected. And the viscosity depends on the type of oil used for extraction. ------------ ------14/05/2020------(OCR) Page 1 of 2 pages. Claims 1.
