[0046] Example 1: Preparation of Portulaca oleracea polyunsaturated fatty acid microcapsules
[0047] % In terms of weight percentage, the specific method steps for preparing Portulaca oleracea polyunsaturated fatty acid microcapsules from Portulaca oleracea residue are as follows:
[0048] (1) Preparation of purslane residue: fresh purslane and drinking water are used as the main raw materials. Fresh purslane is selected, cleaned, chopped, and soaked in water at a weight ratio of 1:3 for 12 hours, and boiled at 80°C Boil for 6 hours and filter to obtain purslane residue.
[0049] (2) Pretreatment using purslane residue as the raw material: using the purslane residue in the processing and production of the purslane or the purslane residue provided in the above steps as the raw material, drying at 70°C, crushing, and sieving 60 mesh , Weighing, filling.
[0050] (3) Extraction of purslane oil by subcritical isobutane extraction technology: Carry out subcritical fluid extraction proc...

[0064] Example 3: Preparation of Portulaca oleracea polyunsaturated fatty acid microcapsules and soft capsules
[0065] % Is calculated by weight percentage, the specific method steps of purslane polyunsaturated fatty acid microcapsules and soft capsules are as follows:
[0066] (1) Pretreatment using purslane residues as raw materials: Fresh purslane and drinking water are used as the main raw materials. The fresh purslane is selected, cleaned, chopped, and soaked in water at a weight ratio of 1:3 for 12 hours. Boil at 80°C for 6 hours, filter to obtain purslane residue, or use purslane residue in the processing of purslane as raw material. Purslane residue is dried at 70°C, crushed, sieved, weighed, and filled. .
[0067] (2) Subcritical isobutane extraction technology to extract purslane oil: Subcritical fluid extraction technology is used, setting conditions: extraction pressure 0.8MPa, extraction temperature 40°C, extraction 150min, and extracting purslane oil prepared by extr...
