Problems solved by technology

The above method has played a certain positive role in the method of extracting rosehip or seed oil, but there are still deficiencies in the above method. Distillation and pressing methods cannot remove harmful impurities in rose oil, and the crude oil has a heavy smell. In many cases, Because the high temperature of the steam will decompose some components in the rose oil and reduce the quality of the rose oil, the solvent extraction method requires a high-concentration solvent, and the rose seeds are dissolved in a high-concentration solvent for a long time. Oleic acid and vitamin E have a certain destructive effect, and the quality of the produced products is poor, making it difficult to enter the international market.

Embodiment Construction

[0020] As shown in FIG. 1 of the present invention, the method for preparing rosehip or seed oil disclosed in the present invention mainly includes four steps of crushing, pressing, vacuum filtration, separation, and storage and purification.

[0021] First sort and remove impurities or rose seeds, fruit stems, sand and dust impurities; use a crusher to crush the rose hips to remove the husk, then crush the rose seeds into granules, and heat them in a wok Within 40--60℃, store in a container below 60℃; after the first pressing, 50% rose oil is extracted from the rose hips or seeds; then the second pressing is performed to extract 35% of the rose hips Or seed oil; then a third press is carried out to extract 10-15% rose hip or seed oil. The rose oil is hydrated, the temperature is controlled at 85-90°C, and the glue and phospholipids are separated by a centrifuge; or a plate filter is used for low-temperature filtration, the temperature is controlled at 10-20°C, and a pressure of 0...

Abstract

The invention relates to a preparation method for rose fruit or rose seed oil, which comprises the main procedures: sorting and removing coarse rose fruit, crushing the rose fruit, removing husks, then breaking rose seeds into particles and heating the particles in a frying pan up to 40 DEG C to 60 DEG C to separate out the rose oil through one to three levels of squeezing, as well as separating out ester gum and phospholipid from the rose oil; and maintaining the purity of the rose oil through filtration, storage and purification.

Description

Technical field [0001] The invention relates to an extraction technology of natural rose fragrance, in particular to a preparation method of rose hip or seed oil, and belongs to the technical field of natural vegetable oil preparation. Background technique [0002] Natural rose seed oil Rosa davurica pall, (botanical name) Rosa davurica mountain thorn rose, also known as thorn rose, wild rose, thorn rose fruit. [0003] Natural rose oil is a vegetable base oil and refined oil extracted from wild rose seeds. It is a 100% pure natural green skin care product. Wild rose seeds are squeezed and refined, free of impurities and good results. [0004] There are similar products abroad. It is called Rosehip seed oil. Rose oil abroad is obtained from Rosehip moschata and Rosa rubiginosa, Rosa canina and seeds. The foreign names are collectively referred to as Rosehip seed oil, and the Chinese name is called Rose seed oil. Wild rose seed oil is fatty oil or fixed oil, mainly esters of fatty...
