Embodiment 1

[0014] A kind of preparation method of celery leaf oil is characterized in that: comprise following processing step,

[0015] (1) Select fresh celery, pick off the celery leaves, soak the celery leaves in clear water for 3 hours, then remove and drain the water;

[0016] (2) Put the drained celery leaves into a pot and boil until boiling, add a small amount of salad oil to the water in the pot to make a layer of oil float on the water surface;

[0017] (3) Grinding the cooked celery leaves, and dissolving the minced celery leaves in ethanol, and then performing ultrasonic treatment, using ultrasonic waves with a frequency of 40KHZ, ultrasonic treatment at 100V for 5 minutes;

[0018] (4) filter the celery leaves that have been ultrasonically treated, and collect the filtrate, and after the filtrate is left to stand for 24 hours, the upper layer oil is obtained;

[0019] (5) Purify the upper layer oil to obtain celery leaf oil.

Embodiment 2

[0021] A kind of preparation method of celery leaf oil is characterized in that: comprise following processing step,

[0022] (1) Select fresh celery, pick off the celery leaves, soak the celery leaves in clear water for 6 hours, then remove and drain the water;

[0023] (2) Put the drained celery leaves into a pot and boil until boiling, add a small amount of salad oil to the water in the pot to make a layer of oil float on the water surface;

[0024] (3) Grinding the cooked celery leaves, and dissolving the minced celery leaves in ethanol, and then performing ultrasonic treatment, using ultrasonic waves with a frequency of 50KHZ, ultrasonic treatment at 150V for 5 minutes;

[0025] (4) filter the celery leaves that have been ultrasonically treated, and collect the filtrate, and leave the filtrate to stand for 48 hours to obtain the upper layer of oily matter;

[0026] (5) Purify the upper layer oil to obtain celery leaf oil.

Abstract

A preparation method for celery leaf oil comprises the following steps: (1) selecting fresh celery leaves, picking celery leaves, putting celery leaves in clear water and immersing for 3-6 h, and taking out and draining water; (2) putting celery leaves subjected to water draining in a pot, boiling to boiling, dropwise adding a little amount of salad oil into the pot, so as to enable a layer of oil-like substance to float on water surface; (3) rubbing cooked celery leaves, putting rubbed celery leaves in ethanol for dissolving, and utilizing ultrasonic wave with the frequency of 40-50 KHz to perform ultrasonic processing under the voltage of 100-150 V for 5 min; (4) filtering celery leaves subjected to ultrasonic processing, collecting the filtrate, and standing for 24-48 h to obtain an upper-layer oil-like substance; and (5) performing purification on the upper-layer oil-like substance, so as to prepare the celery leaf oil. The preparation method is simple and practicable in technology and short in extraction time, and the extracted celery leaf oil is pure in fragrance, bright in color, long in shelf life and uneasy for changing flavor.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of celery leaf oil. Background technique [0002] Celery belongs to Umbelliferae. There are two kinds of cress and celery, which have similar functions, and celery is the best medicinal one.
