Problems solved by technology

At present, fresh roses are used to produce beverages, cosmetics and other products, but the extraction of fresh flower juice is mostly carried out at a high temperature of 98-105°C. The disadvantage is that the nutrients of roses are destroyed, the aroma is lost, and the taste of the produced beverages is poor.
The flower dregs that have been extracted from the juice are discarded, resulting in waste of raw materials and environmental pollution

Embodiment 1

[0012] 100 kilograms of fresh roses, 360 kilograms of water containing 0.2% citric acid, preparation method:

[0013] 1. Add fresh roses to water containing citric acid and extract at 60°C for 2.5 hours;

[0014] 2. Use a centrifuge to separate the flower residue and the extract;

[0015] 3. Filter the extract to remove impurities, and then concentrate the filtrate by ultrafiltration to 1 / 5 of the weight of the extract to obtain concentrated juice;

[0016] 4. Instantaneously sterilize the concentrated juice at high temperature to obtain 70 kg of finished concentrated juice;

[0017] 5. Add appropriate amount of water to distill the flower dregs in step (2) at a temperature of 100°C to obtain a distillate;

[0018] 6. Cool the distillate to 25°C;

[0019] After oil and water are separated with an oil-water separator, 0.0032 kilograms of rose oil is obtained.

Abstract

A process for extracting rose juice and rose oil from fresh rose flower includes such steps as low-temp immersing in the water containing organic acid, separating to obtain juice, concentrating to obtain rose juice, distilling flower dregs, cooling and separating to obtain rose oil. Its product features rich nutrients, strong fragrance, and good taste to eat it.

Description

technical field [0001] The present invention relates to the extraction of natural plants, especially extracting concentrated rose juice and rose oil from roses. Background technique [0002] Roses have a strong fragrance. At present, fresh roses are used to produce beverages, cosmetics and other products, but the extraction of fresh flower juice is mostly carried out at a high temperature of 98-105°C. The disadvantage is that the nutrients of roses are destroyed, the aroma is lost, and the taste of the produced beverages is poor. The flower dregs extracted from the juice are discarded, resulting in waste of raw materials and environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for extracting concentrated rose juice at low temperature using fresh roses as raw materials, and reusing the waste residue to extract rose oil. [0004] The present invention is realized by the following technical scheme: a method ...
