Method for extracting roxburgh rose fine powder by adopting low-temperature microwaves

Abstract

The invention discloses a method for extracting roxburgh rose fine powder by adopting low-temperature microwaves. The method specifically comprises the following steps: weighing fresh roxburgh rose fruits, cleaning the weighed roxburgh rose fruits, cutting the cleaned roxburgh rose fruits, putting the cut roxburgh rose fruits into a container, and putting the container containing the roxburgh rose fruits into a microwave heater for enzyme deactivation; taking out the roxburgh rose fruits which are dried at low temperature, putting the roxburgh rose fruits into a glass tube in microwave extraction equipment, adding an extracting solution into the glass tube, sealing the glass tube, pumping out air in the glass tube until the glass tube is in a vacuum state, controlling the temperature in a microwave heater to be 45-55 DEG C, and keeping the temperature for 50-60 minutes at normal pressure; taking out the extracting solution, performing microwave low-temperature concentration operation, controlling the temperature of the liquid to be lower than 50 DEG C, and performing dehydration treatment on the concentrated solution; and taking out the concentrated solution, and carrying out microwave low-temperature drying to obtain the roxburgh rose fine powder. The disclosed method is simple and efficient, the extraction condition is mild, the extracted effective components are many, the extraction rate is high, the components of the roxburgh rose are not damaged, and the preservation amount of vitamin C in the roxburgh rose reaches 80% or above.

Description

technical field [0001] The invention relates to the technical field of extracting roxburghii, in particular to a method for extracting roxburghii powder using low-temperature microwaves. Background technique [0002] Rosa roxburghii is the fruit of the Rosaceae plant silk reeling flower, also known as Cili and Mulizi, with small thorns densely growing on the peel. The fruit is rich in sugar, vitamins, carotene, organic acids, more than 20 kinds of amino acids, more than 10 kinds of trace elements beneficial to the human body, and superoxide dismutase SOD, especially the extremely high content of vitamin C, which is the highest among current fruits , the content per 100 grams of fresh fruit is 841.58-3541.13 mg, which is 50 times that of citrus, 28 times that of hawthorn fruit, and 10 times that of kiwi fruit. , has high nutritional value and medical value. Prickly pears are produced in large quantities in Guizhou. In the past, the folks mainly said that the fruit of Rosa ...

Problems solved by technology

[0003] In the prior art, the extraction method of Rosa roxburghii has high temperature, low efficiency, and large loss of nutrients. If low-temperature extraction is used, the efficiency is low and the time is long. At the same time, it is difficult to control the temperature when heating, which has great limitations for the extraction of Rosa roxburghii
