Embodiment 1

[0028] A chemical method for increasing the yield of natural plant supercritical extraction, comprising the steps of:

[0029] S1. The waste residue discharged from the upstream concentrated juice unit is air-dried, and the waste residue after the air-drying treatment is screened, then dried and crushed by a dryer, and then weighed and charged;

[0030] S2. Take the charging cylinder out of the extraction kettle, tighten the bolts at the lower end of the cylinder, add the raw materials weighed in S1 into the charging cylinder, then tighten the bolts at the upper end of the cylinder, put them back into the extraction kettle, and then install the extraction The head of the kettle can be tightened;

[0031] S3. Check whether the equipment, pipelines, valves and instruments are normal. After the inspection, set the parameters of the flow controller and related pressure and temperature control instruments, and set the refrigeration temperature controller at 4-6°C;

[0032] S4. Aft...

Embodiment 2

[0043] Embodiment 2: Based on Embodiment 1, the difference is:

[0044] Prepare apple seed oil according to the preparation steps in Example 1, and carry out fatty acid gas chromatographic detection to it, and detection result is as follows table;

[0045] Table 1-Apple seed oil fatty acid composition list

[0046]

[0047] The gas chromatographic analysis results of the fatty acid composition of apple seed oil are shown in Table 1: 4 main fatty acids were identified in total, saturated fatty acids accounted for 7.49%, unsaturated fatty acids accounted for 92.43%; the content of linoleic acid was as high as 62.45%; supercritical carbon dioxide extracted The results show that the supercritical carbon dioxide extraction method has a high extraction rate, and the obtained oil is of good quality, with high linoleic acid content, full flavor, no solvent residue, and high safety.

Abstract

The invention discloses a chemical method for increasing the supercritical extraction yield of natural plants, and belongs to the field of apple seed oil extraction. The chemical method for increasingthe supercritical extraction yield of natural plants strengthens the selectivity, dissolving capacity and extraction efficiency of supercritical CO2 in the extraction process, and selects and adds acertain amount of entrainer to achieve a better extraction effect. Different entrainers and entrainer adding modes and using amounts are investigated through experiments. Anhydrous ethanol is selectedas an entrainer most suitable for the method, different influence factors of supercritical CO2 extraction are investigated, the influence degree of extraction pressure, extraction temperature and extraction time on supercritical extraction of effective components of paederia scandens is analyzed, and the operation range of each factor in the process is selected.

Description

technical field [0001] The invention relates to the field of chemical vessel cleaning, in particular to a chemical method for increasing the output of natural plant supercritical extraction. Background technique [0002] Apples are one of the most common fruits. Apple trees belong to the family Rosaceae, deciduous trees with elliptical leaves and serrated leaves. The fruit is spherical, sweet, crisp and rich in nutrition. It is the crown of the four major fruits in the world. Apple is a low-calorie food that produces only 60 kilocalories per 100 grams. The nutrients in apples are highly soluble and easily absorbed by the body, so they are called "living water". It is beneficial to dissolve sulfur elements and make the skin smooth and tender. It is the choice of many dieters. Because it contains essential nutrients such as proteins, amino acids, vitamins, minerals, and carotene, it can provide essential nutrients for the human body and is easy to digest and absorb. It is a ...
