preparation example Construction

[0036] The invention provides a kind of preparation method of rose essence powder, comprises the following steps:

[0037] (1) Soak rose petals in color-protecting solution for 2-8 hours to obtain color-protecting roses;

[0038] The color protecting solution contains citric acid with a mass concentration of 1.5-5% and magnesium chloride with a mass concentration of 1.5-5%;

[0039] (2) mixing the color-protecting rose obtained in the step (1) with water, adjusting the pH value of the mixture to 4.5-5.5, and rubber milling to obtain a rose slurry;

[0040] (3) filtering the rose slurry obtained in the step (2), taking the filtrate and concentrating it through a reverse osmosis membrane to obtain a rose concentrate;

[0041] (4) drying the rose concentrated solution obtained in the step (3) until the water content is ≤7%, so as to obtain the rose essence powder.

[0042] In the invention, rose petals are soaked in the color-protecting liquid for 2-8 hours to obtain color-prot...

Embodiment 1

[0078] Preparation of color protection solution: 3 kg of citric acid and 3 kg of magnesium chloride were dissolved in 94 kg of water to obtain a color protection solution containing 3% citric acid and 3% magnesium chloride in mass concentration.

[0079] Preparation for extracting raw materials: pick 100kg of fresh red roses within 24 hours, wash them and remove calyxes, pistils, residual petals, remove impurities such as leaves, flower insects, flower branches, etc., and obtain about 80kg of fresh rose petals, stacked with a thickness of no more than 5cm , Store in a cool and dry place for later use, store at a temperature of 15°C and a humidity of 35%RH.

[0080] Before use, pour fresh rose petals into water at 10-15 °C for 0.5 min at a room temperature below 20 °C, and then remove the rose petals and drain the water. The whole process does not exceed 2 hours.

[0081] Place 80 kg of washed rose petals in 80 kg of color-protecting solution, soak for 3 hours at 10°C, remove t...

Embodiment 2

[0086] Preparation of color protection solution: 1.5 kg of citric acid and 2.0 kg of magnesium chloride were dissolved in 96.5 kg of water to obtain a color protection solution containing 1.5% of citric acid and 2% of magnesium chloride in mass concentration.

[0087] Preparation of raw materials for extraction: pick 100kg of fresh pink roses within 24 hours before preparation, remove calyx, stamens, and residual petals after washing, and remove impurities such as leaves, flower insects, flower branches, etc., and obtain about 80kg of fresh rose petals. More than 5cm, store in a cool and dry place for later use, storage temperature is 20°C, humidity is below 38%RH.

[0088] Before use, pour fresh rose petals into water at 10-15 °C for 0.5 min at a room temperature below 20 °C, and then remove the rose petals and drain the water. The whole process does not exceed 2 hours.

[0089] Place 80 kg of washed rose petals in 120 kg of color-protecting solution, soak for 7 hours at 8°C,...

Abstract

The present invention relates to the field of rose processing and provides a preparation method of rose fine powder. The preparation method comprises the following steps: with rose petals as a raw material, the rose petals are soaked in a color protection solution containing citric acid and magnesium chloride with pH adjusted to 4.5-5.5; after the color protection is conducted for 2-8 hours, the rose petals and the color protection solution are directly colloid-milled to obtain rose slurry; the rose slurry is filtered; the filtered rose slurry is subjected to reverse osmosis concentration to obtain a rose concentrate; and the rose concentrate is dried to obtain the rose fine powder. The provided preparation method of the rose fine powder does not conduct any high-temperature operations during extraction and can effectively reduce damages of the preparation process on nutrients and aroma substances in the roses. The obtained rose fine powder by the preparation method is less in rose fragrance loss, has color close to the color of the raw material rose petals, is free of addition of rose essence and other spices to increase the fragrance when used as the raw material for products containing the roses, and also has the color and luster close to those of the roses.

Description

technical field [0001] The invention relates to the field of rose processing, in particular to rose essence powder and its preparation method and application. Background technique [0002] Rose is a clustered deciduous shrub of the genus Rosa, with prickles and needles on its branchlets; well-developed root system, odd-numbered pinnate compound leaves, 5-9 leaflets, and folds on the leaf surface; there are three types of flowers: single, semi-double, and double , single or collective.
