Embodiment 1

[0018] Fresh sheep placenta and embryos are cleaned to remove blood stains and impurities, cut into pieces, freeze-dried at -30 to -50°C, crushed to 20 mesh, collected and mixed evenly to obtain freeze-dried sheep placenta raw materials with a moisture content of 5.20 %, put 120 g of freeze-dried sheep fetal powder raw materials into a 1L extractor, use carbon dioxide with a purity of 99%, and extract at an extraction temperature of 30°C and a pressure of 15MPa. 2 Extract for 120min under the condition of flow rate 15L / h. The obtained extract is decompressed and analyzed and separated in two stages to obtain sheep placenta oil. The primary decompression separation condition is 7.0Mpa and the temperature is 60°C; the secondary pressure separation and extraction condition is below 6MPa and the temperature is 40°C. Finally, 20.84 grams of sheep placenta fat were obtained.

Embodiment 2

[0020] Fresh sheep placenta and embryos are washed to remove blood stains and impurities, cut into pieces, freeze-dried at -30 to -50°C, crushed to 40 mesh, collected and mixed evenly to obtain freeze-dried sheep placenta raw materials with a moisture content of 6 %, put 120g of freeze-dried sheep fetal powder raw material into a 1L extractor, and use carbon dioxide with a purity of 99%, at an extraction temperature of 47.5°C, a pressure of 30MPa, CO 2 Extract for 90min under the condition of flow rate 15L / h. The obtained extract undergoes two stages of decompression analysis and separation to obtain sheep placenta oil. The condition of the primary decompression separation is 7MPa and the temperature is 60°C; the condition of the secondary pressure separation and extraction is below 6MPa and the temperature is 40°C. Finally, 24.84 grams of sheep placenta oil was obtained.

Abstract

The invention discloses a method for extracting sheep placenta essence through super critical carbon diode, wherein, sheep placenta is frozen and dried, lapped into powder, placed in an extracting vessel of super critical equipment; extracting is done by turning on the super-critical carbon diode, then the carbon diode rich with target substance is secondarily reduced pressure, solved and separated; the separated carbon diode continues to take part in the super-critical extracting cycle, the separated effective substance is sheep placenta essence grease in form of oleamen. The invention is of high extracting speed, high extrating rate and simple flow process, guarantees the activity of the effective component of the product, improves the comprehensive utilization of the raw material, and is of obvious economic and social efficiency.

Description

technical field [0001] The invention belongs to the technical field of animal oil extraction, and in particular relates to a method for extracting sheep placenta oil with supercritical carbon dioxide for extracting various nutritional elements and bioactive substances from animal embryos and placenta. It specifically involves the processing and application technology of medicine, cosmetics and health food. Background technique [0002] With the improvement of the quality of life, after people meet the basic living conditions such as food and clothing, the demand for various functional foods with strong functional performance, high nutritional value, and obvious health care effects is becoming more and more urgent. In recent years, extracting a variety of active functional factors from animal embryos and placenta has become a hot spot in the development of new functional foods, among which sheep placenta is the most famous. A large number of experimental studies have proved ...
