preparation example Construction

[0025] Such as figure 1 As shown, the preparation method of the natural Gastrodia elata composite fresh-keeping liquid that the embodiment of the present invention provides comprises the following steps:

[0026] S101: Prunella vulgaris powder according to the material: liquid = 1:6~16 respectively add 60% ethanol solution, room temperature, 600W~1000W, ultrasonic 5min~10min, reflux at 80°C for 2h, extract twice, collect and combine the extracts. Let it settle, filter, and centrifuge the filtrate at 4000r / min for 10min, collect the centrifugate, concentrate under reduced pressure to 1 / 5-1 / 6 of the original volume, recover ethanol, and freeze-dry to obtain Prunella vulgaris extract;

[0027] S102: Dandelion powder according to material: liquid = 1:6-16, add extraction solvent, the extraction solvent is a mixture of ethanol and ethyl acetate (ethanol: ethyl acetate = 1:5-1:5). Room temperature, 600W ~ 1000W, ultrasonic 5min ~ 10min, reflux extraction at 80°C for 2h, extract twi...

Embodiment 1

[0089](1) Preparation of Prunella vulgaris extract: Accurately weigh degreased Prunella vulgaris powder and put it into a flat-bottomed flask, add 60% ethanol solution respectively according to material: liquid=1:6~16, place the flat-bottomed flask in a numerically controlled ultrasonic cleaner 600-1000W, room temperature ultrasound for 5-10 minutes, then reflux extraction at 80°C for 2 hours, extraction twice, and combined extracts were collected. Set aside to settle, filter with four layers of gauze, centrifuge the filtrate at 4000r / min for 10 minutes, discard impurities, collect the centrifugate, and concentrate the collected extract in a rotary evaporator at 45r / min, 45°C, 0.09MPa , until the concentrated volume is 1 / 5-1 / 6 of the original volume, and the ethanol is recovered. The concentrated extract was transferred to a clean petri dish, placed in a refrigerator at -20°C, and frozen into a solid ice cube. Then put the frozen concentrated liquid extract into a vacuum free...

Embodiment 2

[0098] The preparation of natural extract and the preparation of preservative are the same as in Example 1.

[0099] Use the Gastrodia elata fresh-keeping liquid prepared by the method described in Example 1 to keep fresh, and the application method is as follows: put the drained gastrodia elata into a vacuum preservation bag, pour into the fresh above-mentioned fresh-keeping liquid of Gastrodia elata weight 2-4%, seal, and pack in vacuum Gastrodia elata is stored at 20°C, and the storage effect can be observed for 6 months.

Abstract

The invention belongs to the technical field of food preservation and discloses a natural rhizoma gastrodiae compound preservative solution as well as a preparation method and application thereof. Thepreparation method comprises the steps: putting chosen fresh rhizoma gastrodiae into the compound preservative solution to be soaked, fishing out, draining and putting at the shady, cool and ventilating position to be aired; putting into a vacuum preservative bag, filling a fresh preservative into or filling into a PE preservative bag and storing. The compound preservative solution is prepared from materials in parts by weight: prunellae spica extractum, herba taraxaci extractum, egg white extract, chitosan and distilled water. The natural rhizoma gastrodiae compound preservative solution disclosed by the invention can be applied to rhizoma gastrodiae preservation, can delay the rhizoma gastrodiae from corrupting and going bad, can reduce the mass loss rate, the rotting rate, the malondialdehyde content and the total bacterial colony amount of the rhizoma gastrodiae, can inhibit gastrodin from reducing and can keep good nutrition value and excellent commodity characters, color, attractiveness and taste; thus, the rhizoma gastrodiae can be preserved for 12 months or more to the longest, requirements of low season and peak season can be balanced, market supply shelf life is prolonged, product structures are enriched, and the consumption habit of eating fresh rhizoma gastrodiae is met.
