Embodiment 1

[0028] see figure 1 , the present invention provides a kind of technical scheme: a kind of extraction method of anthocyanin: the extraction method of this anthocyanin is as follows:

[0029] Step 1: The petals are crushed, first use running water to clean the double red roses, and then put the washed double red roses into a crushing machine for crushing;

[0030] Step 2: Extraction, adding sucrose to the grinder, and then using the grinder to continue crushing the double red roses, when the sucrose is completely dissolved, a mixed solution is obtained;

[0031] Step 3: Filtration, the mixed solution is filtered, the solid and the solution can be obtained by filtration, and the obtained solution is an anthocyanin semi-finished product;

[0032] Step 4: Antiseptic treatment, first add citric acid to the anthocyanin semi-finished product, citric acid can prevent the anthocyanin from being oxidized, and then pasteurize the anthocyanin semi-finished product, which can reduce the c...

[0043] see figure 1 , the present invention provides a kind of technical scheme: a kind of extraction method of anthocyanin: the extraction method of this anthocyanin is as follows:

[0044] Step 1: The petals are crushed, first use running water to clean the double red roses, and then put the washed double red roses into a crushing machine for crushing;

[0045] Step 2: Extraction, adding sucrose to the grinder, and then using the grinder to continue crushing the double red roses, when the sucrose is completely dissolved, a mixed solution is obtained;

[0046] Step 3: Filtration, the mixed solution is filtered, the solid and the solution can be obtained by filtration, and the obtained solution is an anthocyanin semi-finished product;

[0047] Step 4: Antiseptic treatment, first add citric acid to the anthocyanin semi-finished product, citric acid can prevent the anthocyanin from being oxidized, and then pasteurize the anthocyanin semi-finished product, which can reduce the c...

Embodiment 3

[0058] see figure 1 , the present invention provides a kind of technical scheme: a kind of extraction method of anthocyanin: the extraction method of this anthocyanin is as follows:

[0059] Step 1: The petals are crushed, first use running water to clean the double red roses, and then put the washed double red roses into a crushing machine for crushing;

[0060] Step 2: Extraction, adding sucrose to the grinder, and then using the grinder to continue crushing the double red roses, when the sucrose is completely dissolved, a mixed solution is obtained;

[0061] Step 3: Filtration, the mixed solution is filtered, the solid and the solution can be obtained by filtration, and the obtained solution is an anthocyanin semi-finished product;

[0062] Step 4: Antiseptic treatment, first add citric acid to the anthocyanin semi-finished product, citric acid can prevent the anthocyanin from being oxidized, and then pasteurize the anthocyanin semi-finished product, which can reduce the c...

Abstract

The invention belongs to the technical field of oral beverages. The invention relates to an extraction method of anthocyanin. The extraction method of anthocyanin comprises the following steps: smashing petals, extracting, filtering, carrying out preservative treatment and packaging. The double-petal red rose is rich in anthocyanin; however, no person develops and utilizes the resource all the time; according to the method disclosed by the invention, anthocyanin rich in the double-petal red rose flowers can be extracted; anthocyanin is used for producing the oral beverage; therefore, the highanthocyanin content of the double-petal red rose is used for meeting the high requirements of the oral beverage industry on anthocyanin; according to the method disclosed by the invention, anthocyaninin the double-petal red rose can be sufficiently extracted; by adding a small amount of citric acid into the anthocyanin semi-finished product, the anthocyanin semi-finished product can be preventedfrom being oxidized by oxygen in the storage process, pasteurization is conducted on the anthocyanin semi-finished product, the content of bacteria in anthocyanin can be reduced, and therefore the quality guarantee period of anthocyanin is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of oral beverages, in particular to a method for extracting anthocyanins. Background technique [0002] Anthocyanins, also known as anthocyanins, are water-soluble natural pigments that widely exist in plants in nature. They are colored aglycones obtained by hydrolysis of anthocyanins. Most of the main coloring substances in fruits, vegetables, and flowers Related to it, under the conditions of different pH values ​​of plant cell vacuoles, anthocyanins make the petals show colorful colors. There are more than 20 known anthocyanins, and there are 6 important ones in food, namely geranium pigment and cyanidin pigment. , delphinium pigment, peony pigment, morning glory pigment and mallow pigment, anthocyanins in the natural state exist in the form of glycosides, called anthocyanins, and there are few free anthocyanins. With the development of science and technology People pay more and more attention to the saf...
