Embodiment 1

[0013] Example 1: A method for preparing polyphenol extracts from double red rose dregs, which consists of the following steps: (1) rose dregs pretreatment: the double red rose dregs after extracting the essential oil are washed with water, After the receptacle is removed, the pulp is beaten to obtain rose pulp.

[0014] (2) Preparation of fruit pulp: After washing papaya, tomato and lemon with drinking water, they were soaked in normal saline for 30 minutes, and after washing again, they were beaten with a pulverizer to obtain papaya pulp, tomato pulp and lemon pulp respectively.

[0015] (3) Polyphenol extraction: mix according to the ratio of 1 part of rose pulp (water content 85%) and 5 parts of pure water, adjust the pH value to 4.5 with sodium dihydrogen phosphate and disodium hydrogen phosphate, and the temperature is 40 °C , add 1 part of papaya pulp, 1 part of tomato pulp, and 1 part of lemon pulp to 100 parts by weight of rose pulp for processing. The treatment time ...

Embodiment 2

[0017] Embodiment 2: a kind of method utilizing double petal red rose pomace to prepare polyphenol extract, it is made up of following steps:

[0018] (1) Rose dregs pretreatment: After extracting the essential oil, the double red rose dregs are washed with water, the receptacles are removed, and then beaten to obtain rose dregs.

[0019] (2) Preparation of fruit pulp: After washing papaya, tomato and lemon with drinking water, they were soaked in normal saline for 30 minutes, and after washing again, they were beaten with a pulverizer to obtain papaya pulp, tomato pulp and lemon pulp respectively.

[0020] (3) Polyphenol extraction: mix according to the ratio of 1 part of rose pulp (water content 85%) and 5 parts of pure water, adjust the pH value to 6.0 with sodium dihydrogen phosphate and disodium hydrogen phosphate, and the temperature is 55 °C , add the papaya of 5 parts by weight, the tomato of 5 parts, the lemon of 3 parts by 100 parts by weight of rose pulp and process...

Embodiment 3

[0022] Example 3: A method for preparing polyphenol extracts using double-petal red rose dregs, which consists of the following steps: (1) rose dregs pretreatment: after the essential oil is extracted, double-petal red rose dregs are washed with water, After the receptacle is removed, the pulp is beaten to obtain rose pulp.

[0023] (2) Preparation of fruit pulp: After washing papaya, tomato and lemon with drinking water, they were soaked in normal saline for 30 minutes, and after washing again, they were beaten with a pulverizer to obtain papaya pulp, tomato pulp and lemon pulp respectively.

[0024] (3) Polyphenol extraction: After mixing 1 part of rose pulp (water content 85%) and 5 parts of pure water, adjust the pH value to 5.0 with sodium dihydrogen phosphate and disodium hydrogen phosphate, and the temperature is 50 ℃, add 4 parts of papaya pulp, 3 parts of tomato pulp, and 2 parts of lemon pulp to 100 parts by weight of rose pulp for processing, and the processing time...

Abstract

The invention provides a method for preparing polyphenol extracts by polyphyll red rose flower residues. The method is characterized in that pulped polyphyll red rose flower residues are jointly treated with various kinds of fruit to release polyphenol substances. The method comprises the following concrete steps of rose flower residue pretreatment: performing water washing and receptacle removal;performing pulping to obtain rose flower residues; fruit pulp preparation: respectively pulping pawpaw, tomato and lemon by a crushing machine to obtain pawpaw pulp, tomato pulp and lemon pulp; polyphenol extraction: using the polyphyll red rose flower residues after the essential oil extraction as raw materials; adding the pulped pawpaw, tomato, lemon and flower residue for heat insulation together. The release quantity of polyphenol in the flower residues can be obviously improved.

Description

technical field [0001] The invention discloses a method for preparing polyphenol extract by using double-petal red rose residue, which belongs to the technical field of bioengineering. Background technique [0002] Rose( Rosa rugosa ) belongs to Rosaceae (Rosaceae) and has a long history of cultivation in my country. The main varieties are "Double Petal Rose" and "Bitter Rose", which are widely distributed in China. , Kushui in Gansu, Shangshui and Yanling in Henan, Hotan in Xinjiang and Meishan in Sichuan. Among them, Pingyin, Shandong is the famous "Hometown of Roses" in my country. The total rose planting area exceeds 60,000 mu, accounting for more than 30% of the national planting area, and the annual output of roses is more than 10,000 tons. "Pingyin Double Red Rose" is the only rose variety certified by the former Ministry of Health that can be used as a food raw material, and its health care value has great potential for development. Rose pomace is the residual part...
