Embodiment 1

[0024] Take 50 kg of fresh green plums after sorting and soak them in 200 liters of petroleum ether for 36 hours and then filter; the filtrate (about 200 liters) is decompressed with a rotary evaporator to remove petroleum ether (bath temperature 40°C, vacuum degree 17.3-21.3kPa, condensed The receiver is condensed with brine calcium chloride at about -10°C, and the receiver is cooled and kept warm with the same brine). When all the filtrate is added and concentrated under reduced pressure to a semi-solidified state (crude paste), most of the solvent has been recovered. Crude The amount of solvent in the paste is very small; break the vacuum, add 9 liters of degassed absolute ethanol (to take out the remaining solvent) and mix well with the crude paste, the vacuum degree rises to 6.7-8.0kPa, and the bath temperature is 40°C to evaporate the ethanol- Petroleum ether was mixed with a solvent to obtain 118.9 grams of green plum extract.

Embodiment 2

[0026] Take 50 kg of fresh red plums after sorting and soak them in 200 liters of petroleum ether for 36 hours and then filter; The receiver is condensed with brine calcium chloride at about -10°C, and the receiver is cooled and kept warm with the same brine). When all the filtrate is added and concentrated under reduced pressure to a semi-solidified state (crude paste), most of the solvent has been recovered. Crude The amount of solvent in the paste is very small; break the vacuum, add 9 liters of degassed absolute ethanol (to take out the remaining solvent) and mix well with the crude paste, the vacuum degree rises to 6.7-8.0kPa, and the bath temperature is 40°C to evaporate the ethanol- Petroleum ether was mixed with a solvent to obtain 118 grams of red plum extract.

Embodiment 3

[0028] Take 50 kilograms of fresh wintersweet after sorting and soak in 200 liters of petroleum ether for 36 hours and then filter; -10 ℃ brine calcium chloride condenses, the receiver is cooled and kept warm with the same brine), when all the filtrate is added and concentrated under reduced pressure to a semi-solidified state (crude paste), most of the solvent has been recovered, the crude paste The amount of solvent in the medium is very small; break the vacuum, add 10 liters of degassed absolute ethanol (to take out the remaining solvent) and mix well with the crude paste, the vacuum degree rises to 6.7-8.0kPa, and the ethanol-petroleum is evaporated at a bath temperature of 40°C Ether mixed with solvents to obtain 130.9 grams of green plum extract.

Abstract

The invention discloses a method for preparing a plum blossom extract. The method comprises the following steps of: leaching fresh half-open plum blossoms serving as a raw material by using petroleum ether; removing the petroleum ether from a deslagged leaching liquor to obtain an extract; and finally sterilizing the extract at low temperature to obtain a finished plum blossom extract. The invention also provides plum blossom incense perfume prepared from the plum blossom extract prepared by the method. The plum blossom incense perfume can be prepared by diluting the plum blossom extract prepared by the method by using a diluent until the content of the extract is 0.3 to 0.7 percent. The invention has the advantages that the plum blossom extract is prepared from fresh plum blossoms, an incense product is prepared from the plum blossom extract, the aroma releasing time of plum blossoms is prolonged, and the source of a plum blossom raw material is adequate and guaranteed; and the cost of the raw material is reduced, the yield of the prepared extract is high, the product maintains the original aroma of the plum blossoms, and the production process is advanced and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the deep processing technology of plum blossoms. Background technique [0002] Plum blossom, the flower of the plum tree, leaves open first in cold winter, with five petals in pink, white, red and other colors. Plum blossoms contain the aesthetic tendency, emotional context and moral standards of the Chinese nation. Plum blossom is the soul of the Chinese nation, and it is a matter of course that it is respected as the "national flower". [0003] The fragrance of plum blossoms has the characteristics of "clear" and "quiet", but the flowering period of plum blossoms is only about one month, and people only have a short time to appreciate the fragrance of plum blossoms. Plum blossoms can extract aromatic oils. According to Zhao Xuemin’s "Compendium of Materia Medica Supplements": "People in Haicheng are good at steaming plums and rose dew, which is like the method of making wine. A little dew in each pot of wine will be fragran...
