Embodiment 1

[0028] A method for generating rose water is provided, comprising the steps of:

[0029] (1) Low-temperature dry extraction: use a low-temperature vacuum circulation extraction device to distill and extract from fresh roses under the condition of 30Ⅲ to obtain the rose stock solution;

[0030] (2) Fill the rose dew stock solution in step (1) into a sterilized plastic bottle, so that the rose dew stock solution fills the entire plastic bottle, discharges the air in the plastic bottle, and fills a single plastic bottle. The residual air in the bottle is 0.5%, and the percentage is the volume percentage of the residual air in the package;

[0031] (3) Carry out high-pressure sterilization treatment with the filled rose dew stock solution, the temperature of sterilization is 25Ⅲ, the pressure of sterilization is 400MPa, and the holding time is 10min;

[0032] (4) After the high-pressure sterilization of the system is completed, the pressure will be 0MPa. After all the water in th...

Embodiment 2

[0039] A method for producing rose water is provided, comprising the steps of:

[0040] (1) Low-temperature dry extraction: using a low-temperature vacuum circulation extraction device, distilled and extracted from fresh roses under 40Ⅲ conditions to obtain the rose stock solution;

[0041] (2) Fill the rose dew stock solution in step (1) into a sterilized plastic bottle, so that the rose dew stock solution fills the entire plastic bottle, discharge the air in the plastic bottle, and fill a single plastic bottle The residual air content is 1%, and the percentage is the volume percentage of the residual air in the package;

[0042] (3) Carry out high-pressure sterilization treatment with the filled rose dew stock solution, the sterilization temperature is 25Ⅲ, the sterilization pressure is 350MPa, and the pressure holding time is 15min;

[0043] (4) After the high-pressure sterilization of the system is completed, the pressure will be 0MPa. After all the water in the high-pres...

Abstract

The invention relates to a method for producing rose hydrosol. The method is mainly characterized in that a low-temperature vacuum circulation extraction device is adopted, and the original rose flower liquid is obtained from rose flowers under the condition that the temperate ranges from 30 DEG C to 40 DEG C in a distillation and extraction mode; the original rose flower liquid is sterilized through the superhigh pressure technology, and the rose hydrosol is obtained. The rose hydrosol obtained through the method keeps the flavor and functional components of rose flower liquid to the maximum extent, microorganisms in the rose flower liquid can be fully killed out, the national drinking water standard requirement is met, and the microbiological indicator meets the commercial sterilization requirement within the normal shelf life.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for producing rose water. Background technique [0002] Rose is a precious medicinal material, sweet and slightly bitter, warm in nature. Rose Hydrosol is extracted from roses by drying at low temperature. Rose Hydrosol contains low energy and is rich in citronellol, nerol, geraniol, phenylethyl alcohol and other multi-volatile aroma components. It has a charming aroma and a wide consumer group, which is in line with the healthy development trend of modern beverages. [0003] With the continuous advancement of science and technology, ultra-high pressure sterilization technology is becoming more and more mature at home and abroad, especially in developed countries. The research on high-pressure sterilization technology in China is still in its infancy, but some progress has been made in various aspects. Ultra-high pressure technology has incomparable advantages...
