Problems solved by technology

The traditional pressing method has the advantages of good oil quality, light color, pure flavor, etc., but the amount of residual oil in the cake residue after pressing is high, the oil yield is low, and the energy consumption is large; the supercritical extraction method has a high oil yield and oil quality. It is also better, but the cost is too high and it is not suitable for large-scale production; the extraction method has a high oil yield, and the leached crude oil contains more impurities, darker color, high oil yield, and is easy to achieve large-scale production

Embodiment Construction

[0014] A kind of East China raspberry oil production process:

[0015] A. Dry the raspberry kernels in East China, and control the moisture content to 4%;

[0016] B. Put the dried East China raspberry kernels into a freezer at -25°C for 6 hours, then place them in a vacuum environment at -10°C for 7 hours, and finally place them in a vacuum environment at 45°C for 3 hours;

[0017] C, pulverize the East China raspberry kernels obtained after the treatment of B, and sieve with a 20 mesh sieve;

[0018] D. CO 2 Supercritical extraction, fluid extraction pressure is 40MPa, extraction temperature is 40°C, CO 2 Fluid flow is

[0019] 1000L / h, the extraction time is 70 minutes, and the crude oil of East China raspberry kernel is obtained;

[0020] E, ultrafiltration removes lipoxygenase, selects the ultrafiltration membrane of molecular weight cut-off 80-120kD, carries out ultrafiltration process to the East China raspberry oil after filtering;

[0021] F. Ultraviolet irradiat...

Abstract

The invention provides a supercritical extraction process for Rubus Chingii Hu oil. The Rubus Chingii Hu oil is obtained through the steps of CO2 supercritical extraction and hyperfiltration. In the production process, particularly in the refining process of the Rubus Chingii Hu oil, a chemical reagent is not added, a purely physical method is adopted for refining, the obtained Rubus Chingii Hu oil reserves special rutin, tiliroside, quercetin and other flavonoids as well as vitamin E and other active materials of the Rubus Chingii Hu, and is free of solvent residues and pollution, good in safety and high in quality. Since no chemical reagent is added in the refining process, and no chemical reagent residue is realized, the Rubus Chingii Hu oil can be used as high-end edible oil and high-end cosmetic or a pharmaceutical additive. The Rubus Chingii Hu oil is fragrant in smell and unique in flavor, can be widely used for cooking various foods and dishes, has a relatively high nutritive value and a healthcare health-preserving effect, ensures high-antioxidant active ingredients and is particularly suitable for being popularized in the technical field of small-batch special oil production.

Description

technical field [0001] The invention relates to a method for supercritical extraction of raspberry oil in East China, and belongs to the technical fields of biology and new medical technology, modern agricultural technology, deep processing of agricultural products and modern storage and transportation, and value-added processing of agricultural and forestry products and special resources. Background technique [0002] East China raspberry, that is, the plant raspberry of the genus RubusLinn in the family Rosaceae (English name: Raspberry, Latin name: RubusChingiiHu, Chinese name: raspberry, raspberry, alias: raspberry, raspberry, small tray, farming bubble , Weng twist, milk mother, etc.) seeds. Raspberry is called "ruby" in Europe and America, and it is the third generation golden fruit. Raspberry seed oil is a rare vegetable oil, which is a high-grade edible oil and cosmetic raw material. [0003] Raspberry seeds are a by-product of winemaking or juice production an...
