Embodiment 1

[0016] Embodiment one: a kind of preparation method of rose spice, comprises the steps:

[0017] (1) Raw material pretreatment: pre-freezing temperature -30°C, vacuum degree 0.092MPa, microwave power 6 watts, make the water content of the raw material 5.5%, complete drying, and crush the dried raw material into 40-mesh fine particles;

[0018] (2) Supercritical extraction: put crushed rose raw materials into the extraction kettle of supercritical extraction equipment, and perform supercritical carbon dioxide extraction in stages. The temperature of the extraction kettle is 35°C, and the flow rate of carbon dioxide is 17 liters / minute. After the supercritical carbon dioxide extraction is finished, take out the rose flower extract in the separation kettle of the supercritical extraction equipment, the temperature of the separation kettle is 53°C, and the pressure of the separation kettle is 5.0Mpa;

[0019] Supercritical extraction is divided into four stages according to the ex...

Embodiment 2

[0023] Embodiment two: a kind of preparation method of rose spice, comprises the steps:

[0024] (1) Raw material pretreatment: carry out microwave vacuum freeze-drying on fresh roses, the pre-freezing temperature is -20°C, the vacuum degree is 0.01MPa, and the microwave power is 8 watts, so that the water content of the raw material is 7.5%, and the drying is completed. The final raw material is crushed into 60 mesh fine particles;

Abstract

The invention relates to a preparation method of rose perfume. Firstly, fresh roses are frozen and dried in vacuum and then are smashed into 40-60 mesh fine particles, and then the raw materials are extracted through a supercritical carbon dioxide extraction method in different stages; in the first stage, extraction pressure intensity is 8-14 MPa, and extraction time is 60-70 s; in the second stage, extraction pressure intensity is 15-21 MPa, and extraction time is 50-60 s; in the third stage, extraction pressure intensity is 22-28 MPa, and extraction time is 40-50 s; in the fourth stage, extraction pressure intensity is 28-34 MPa, and extraction time is 30-40 s; finally, the rose perfume is obtained through membrane passing and decompression concentration. The preparation method is simple, the content of aroma substances of the rose perfume is high, aroma is pure and natural, stability is good, and the perfume has the vivid aroma characteristic of natural roses and can be widely used for perfuming daily chemicals, tobacco and other products.

Description

technical field [0001] The invention relates to a method for preparing rose fragrance, belonging to the technical field of fragrance preparation. Background technique [0002] Roses are full of fragrance and are loved by people. They are an important floral fragrance raw material. The essential oil prepared from roses has a strong aroma and is called "liquid gold". It is widely used in food, cosmetics and essences. Spices and other fields have great application value and economic value. [0003] At present, the production of rose spices in my country mainly adopts traditional steam distillation and organic solvent extraction methods. Due to backward technology and poor technical conditions, the product yield is low, the product quality is unstable, and the utilization of rose resources is extremely insufficient. Contents of the invention [0004] The purpose of the present invention is to solve the problems of the existing rose spices in the extraction and preparation pro...
