Problems solved by technology

The production process of rosemary fat-soluble antioxidants in this patent application is a supercritical carbon dioxide extraction method, which has high production costs, low raw material utilization, and a single product, which is limited to fat-soluble antioxidants and has a darker color.
[0006] In addition, the existing rosemary antioxidant products do not consider the content of carnosic acid, but only consider the content of total phenols. As the main component of rosemary fat-soluble antioxidants, carnosic acid is an unstable substance. It is difficult to guarantee its stability due to the process, and it has not publicly stated the content of carnosic acid in its extracted products

Embodiment 1

[0031] Example 1: Preparation of Comprehensive Extraction of Rosemary and Instant Fat-soluble Antioxidant

[0032] The raw material is rosemary produced in Luxi County, Hunan Province.

[0033] Collect tender stems and leaves, dry in the shade naturally, then mechanically crush and pass through a 40-80 mesh sieve;

[0034] Take 10 kg of sieved raw material, put it into a 100L percolation extraction tank with an oil-water separator, and steam distill for 30-60 minutes at a temperature not exceeding 85°C to obtain 190 grams of rosemary essential oil.

[0035] In the residue after distillation, add 100L of 70%-95% ethanol according to the ratio of material to liquid 1:10, extract by percolation for 1-3 hours, filter out the residue of medicinal materials in the extract, and obtain a yellow-green extract;

[0036]Recover ethanol from the extract, add pure water during the process of recovering ethanol, the ratio of the amount of water added to the weight of the raw material befor...

Embodiment 2

[0040] Example 2: Preparation of Comprehensive Extraction of Rosemary and Instant Fat-soluble Antioxidant

[0041] The extraction method of this example is basically the same as that of Example 1, the difference is that the low boiling point solvent used in decolorization is changed to petroleum ether; the edible oil is soybean oil (purchased from Nanhai Oil Industry (Chiwan) Co., Ltd., Arowana soybean oil ).

Embodiment 3

[0042] Example 3: Preparation of Comprehensive Extraction of Rosemary and Instant Fat-soluble Antioxidant

[0043] The extraction method of this example is basically the same as that of Example 1, the difference is that the low boiling point solvent used during decolorization is changed to cyclohexane; the edible oil is palm oil (purchased from Nanhai Oil Industry (Chiwan) Co., Ltd., Arowana palm Oil).

Abstract

The invention relates to the extraction and utilization of rosmarinus officinalis, and discloses a method for comprehensively extracting the rosmarinus officinalis and preparing a fat-soluble instant antioxidant. The method comprises the following steps of: mincing raw materials rosmarinus officinalis tender stems or leaves which are dried in shade, and distilling the minced rosmarinus officinalis tender stems or leaves by using water vapor to obtain rosmarinus officinalis essential oil and distillation residues; and performing percolation extraction on the distillation residues by using ethanol, performing ethanol recovery treatment on extracting solution, obtaining a water-soluble antioxidant from a water phase, dissolving precipitates by using a low-boiling solvent, and decreaming a carnosic acid into cooking oil after decoloring; and performing concentration, and recovering the solvent to obtain a fat-soluble instant antioxidant product with the carnosic acid content of 5 to 20 percent. The method has the advantages of high yield, full raw material utilization, low production cost and the like; and in addition, the application performance of a rosmarinus officinalis antioxidant product is greatly improved, and the rosmarinus officinalis antioxidant can be more conveniently and efficiently used.

Description

technical field [0001] The invention relates to the extraction and utilization of rosemary, in particular to a comprehensive extraction method of various active components of rosemary, in particular to a method for preparing fat-soluble instant antioxidants from rosemary raw materials. Background technique [0002] rosemary( Rosmarinus officinalis ), also known as tansy, is a perennial woody plant of the genus Salvia. It is warm in nature and pungent in taste. Its main active ingredients include rosemary essential oil, rosmarinic acid, carnosic acid, carnosol, etc. [0003] Rosemary is a world-famous delicious vegetable.
