Example Embodiment
[0020] Example 1
[0021] Add 800 mL of 0.2mol / L disodium hydrogen phosphate-0.1mol / L citric acid buffer solution with pH 6 to 100 g of winter plum flowers, heat to 80℃ for sterilization, cool to 40℃, and add 0.5U to it β -Glucosidase (manufactured by Sigma), placed in a gas bath constant temperature shaker for enzymatic hydrolysis at 37°C for 4 hours, filtered and separated the wintersweet extract and the wintersweet extract to obtain 820 g of the wintersweet extract.
Example Embodiment
[0050] Example 2
[0051] 250 g of the winter plum extract obtained from Example 1 was added to a 500 mL three-necked flask, steam was introduced, and steam distillation was carried out. The steam containing aroma components was condensed in the condenser tube connected to the side to obtain 50 g containing Aqueous solution of aroma components.

The invention discloses a preparation method of meratia praecox extract for improving aroma and application thereof, and belongs to the technical field of perfume preparation. The method comprises the following steps of: adding meratia praecox fresh flower into disodium hydrogen phosphate-nitric acid buffer solution; sterilizing; cooling; adding glucoside lytic enzyme; placing in a vapor bathing constant temperature vibrator for enzymolysis; heating to deactivate enzyme; cooling; separating meratia praecox through centrifugal separation or filtration to obtain clear meratia praecox extract; then concentrating the clear meratia praecox extract under reduced pressure, concentrating the clear meratia praecox extract through a reverse osmosis membrane or performing freezing concentration to obtain meratia praecox raw material concentrate; or treating the clear meratia praecox extract through a steam distillation method, a solvent extraction method, a membrane concentration method, a resin adsorption method, a supercritical extraction method or a reduced pressure concentration method to prepare the meratia praecox extract. The meratia praecox extract, meratia praecox raw material concentrate or aroma concentrate product prepared by the method has sufficient and strong flower aroma; and both intensity and richness of the aroma exceed those of the conventional product.
Description
technical field [0001] The invention relates to a preparation method and application of an aroma-improving wintersweet extract, in particular to an enzyme treatment method for an aroma-improving wintersweet extract and wintersweet spice, which belongs to the technical field of spice preparation. Background technique [0002] Wintersweet is a famous traditional garden flower in my country. Its fragrance is elegant and fragrant, and it also has many pharmacological functions. Wintersweet flower essential oil has a cold and clear aroma, overflowing and sweet, and is a high-grade natural floral raw material. [0003] Scientists from Japan and other countries have compared the components of wintersweet essential oil with rose and jasmine essential oils. The results show that the identified components of wintersweet essential oil are higher than those of rose essential oil and jasmine essential oil, which fully demonstrates the utilization potential of wintersweet essence. Howeve...
