Embodiment 1
[0033] (1) Preparation of natural organic trace element concentrate
[0034] Select CO 2 As an extractant, heat up and pressurize to make the extractant form a supercritical fluid under the conditions of temperature > 31°C and pressure > 7.38MPa; use the leaves of high-quality palm trees grown in the United States as raw materials, and crush 1kg of raw materials to a particle size of 40 The purpose is placed in the extraction device, and the system is flushed into the supercritical fluid CO 2 And heat up, pressurize, make supercritical CO 2 The fluid is in full contact with the palm leaves, in supercritical CO 2 Under the action of fluid, extract at a temperature of 31°C and a pressure of 40MPa for 4 hours, in which the required supercritical CO 2 The flow rate of the fluid is 21L / min, and the trace element extract is extracted; the trace element extract is sterilized and then vacuum-sealed to obtain a natural organic trace element concentrate. 9.2g of natural organic trac...
Embodiment 2
[0041] (1) Select CO 2 As an extractant, by heating up and pressurizing, the extractant becomes a supercritical fluid under the conditions of temperature>31°C and pressure>7.38MPa; using palm tree leaves as raw materials, 1kg of raw materials are crushed and pretreated to 60 meshes, and placed In the extraction device, the system is flushed with supercritical fluid CO 2 And heat up, pressurize, make supercritical CO 2 The fluid is in full contact with the palm tree, in supercritical CO 2 Under the action of fluid, at a temperature of 60 ° C and a pressure of 8 MPa, extract for 0.5 h to obtain trace element extracts, in which supercritical CO 2 The flow rate of the fluid is 0.02L / min; the trace element extract is sterilized and then vacuum-sealed to obtain a natural organic trace element concentrate. 0.37g of natural organic trace element concentrate can be obtained per 1kg of raw materials; after testing, the natural organic trace element concentrate contains nine essential...
Embodiment 3
[0047] (1) Select unpolluted natural mineral water, which contains calcium (Ca), magnesium (Mg), potassium (K) and other essential macroelements, essential trace elements and dissolved oxygen for human body; the main components of this natural mineral water are: Sodium 60mg / L, Calcium 72mg / L, Magnesium 12.5mg / L, Potassium 90mg / L, Iron 0.03mg / L, Iodine 0.010mg / L, Selenium 0.001mg / L, Zinc 0.07mg / L, Metasilicate 65mg / L L;
[0048] (2) Use high temperature sterilization to sterilize the natural mineral water, and then use pure water to dilute the natural mineral water under aseptic conditions to reduce the content of major elements and trace elements to an appropriate range. Among them, mineral water and pure The volume ratio of water is 1:19;
[0049] (3) Select CO 2 As an extractant, by heating and pressurizing, the extractant can form a supercritical fluid under the conditions of temperature > 31°C and pressure > 7.38MPa; using high-quality palm leaves as raw materials, 1kg o...
