Embodiment

[0028] Supercritical CO 2 The specific extraction methods for extracting Trichosanthes seed oil include:

[0029] (1) Raw materials: mature seeds of Trichosanthes chinensis;

[0030](2) Drying: Dry the Trichosanthes seeds in an oven at a constant temperature of 60°C for 2 to 10 hours or dry naturally, with a water content of about 6%.

[0031] (3) pulverization: pulverize Trichosanthes seeds with a high-speed pulverizer, and sieve (20 orders);

[0032] (4) Supercritical CO 2 Extraction: put the crushed Trichosanthes seeds into supercritical CO 2 In the extraction device, adjust the extraction temperature to 45.25°C, the extraction time to 179.4min, and the extraction pressure to 30.15MPa. CO 2 The flow rate is 20L / h, and the time is 3 hours, and the trichomona seed oil is directly collected in a triangular flask at the outlet of the extraction kettle. The extracted trichosanthes seed oil is a light yellow-brown, clear oil with special flavor of trichosanthes seed oil; th...

Abstract

The invention relates to a method for extracting Tricosanthes kirilowii Maxim oil by supercritical CO2 belonging to the food processing field. The material and process comprises the following steps: drying, crushing, sieving the Tricosanthes kirilowii Maxim, and extracting the Tricosanthes kirilowii Maxim by supercritical CO2 at extraction temperature 45. 5 DEG C and a pressure of 30. 15MPa for 179. 4min. The extraction rate of the Tricosanthes kirilowii Maxim oil is 32. 70-32. 80and the purity is higher than 99 The Tricosanthes kirilowii Maxim extraction process by supercritical CO2 provides a novel method for deep treatment of the Tricosanthes kirilowii Maxim and is useful for the research of Tricosanthes kirilowii Maxim extraction by supercritical CO2. The extraction method of the invention has advantages of strong operability, good security, high repeatability, simple process, high product purity and non-pollution, and can be used in Tricosanthes kirilowii Maxim oil production.

Description

1. Technical field [0001] The present invention relates to supercritical CO 2 The method for extracting Trichosanthes seed oil belongs to the field of food processing, and is specially used for the supercritical CO of Trichosanthes seed oil 2 extract. 2. Background technology [0002] Trichosanthes seeds, also known as Gualou seeds, Gualouren, Trichosanthes kernel, Trichosanthes real, etc., are the dried and mature seeds of Cucurbitaceae Trichosanthes or Trichosanthes bilobata (see reference: "Chinese Pharmacopoeia" 2005 edition). The dried and mature seeds of Trichosanthes chinensis are listed in the Pharmacopoeia of the commonly used traditional Chinese medicine Gualouzi. Seeds contain many beneficial fatty acids, such as: punicic acid, linoleic acid, oleic acid, palmitic acid, linoleic acid, linoleic acid, etc. (see references: He Xiangjiu, Qiu Feng, Yao Xinsheng. [J]. Foreign Medicine. Herbal Medicine Volume, 2002, 17(1): 11~13.). [0003] At present, the extraction ...
