Problems solved by technology

[0005] At present, most of the Rhodiola rosea on the market are eaten by cooking, soaking in wine or stewing meat, but the above direct consumption methods can only absorb 20 to 40% of the nutrition of Rhodiola rosea, and 100% of it is Sixty to eighty will be wasted

Abstract

The invention discloses an extraction method for a rhodiola rosea essence substance. The extraction method comprises the following steps: (1) pre-treating rhodiola rosea and purifying water; (2) extracting the pre-treated rhodiola rosea and the pure water; (3) roughly filtering cooled rhodiola rosea soup and precisely separating; (4) filtering precisely-filtered liquid with a micro-pore membrane with the pore diameter of 0.25-0.45 micron; (5) concentrating refined purified liquid by using a reverse osmosis membrane at room temperature; (6) decompressing and concentrating the rhodiola rosea soup concentrated by the reverse osmosis membrane; (7) finally, obtaining an essence extractive. Compared with the prior art, the extraction method for the rhodiola rosea essence substance is used for extracting the essence of the rhodiola rosea, greatly improves the nutrition absorption rate, and has the advantages of high efficiency, environmental friendliness, safety, guarantees of the activity of effective components and the like; the taste and the nutritional components of the rhodiola rosea are kept and the rhodiola rosea essence substance is convenient to carry; the effects of the expensive rhodiola rosea can be developed completely.

Description

technical field [0001] The invention relates to the field of health care products, in particular to a method for extracting rhodiola essence. Background technique [0002] Rhodiola rosea, perennial herb, 10-20 cm high. The roots are thick, conical, fleshy, brownish yellow, with many fibrous roots at the root neck. Rhizome short, stout, terete, covered by numerous imbricate scale-like leaves. Several flower stems are extracted from the leaf axils at the top of the stem. The upper and lower parts of the flower stems have fleshy leaves, the leaves are elliptic, with serrated edges, sharp apex, cuneate base, almost sessile. Cymes terminal, flowers red. Harvest from July to September. [0003] Rhodiola has a long history of application. More than 2,000 years ago, people on the Qinghai-Tibet Plateau used it as medicine to strengthen their bodies and resist adverse environmental influences. Folks often use it to boil water or soak wine to eliminate fatigue or resist the cold i...
