preparation example Construction

[0025] The preparation method of toi toi essential oil, hydrosol and fruit tea of ​​the present invention comprises the following steps:

[0026] 1) Pre-treat the selected toi toi flowers / leaves / fruits and spread them on the material tray of the freeze dryer;

[0027] 2) The freeze dryer cools down to -20~-45°C to promote the dissolution of the essential oils in the flowers / leaves / fruits during the freezing process, and then heats up to 20~40°C, and vacuumizes the essential oils and Moisture is extracted, preferably, the vacuum degree of vacuuming is -0.09~-0.1MPa, which is beneficial to the gasification and sublimation of essential oil and water, and the oil-water separation membrane is installed at the air suction port. Preferably, the pore size of the oil-water separation membrane is 0.5-5nm, and the water Molecules can pass through the oil-water separation membrane smoothly. The molecules of the essential oil are relatively large and are intercepted by the oil-water separa...

Embodiment 1

[0041] 1) Select 10kg of the above-mentioned tortoise buds, wash them with purified water to remove dust and impurities, and then dry them, then soak them in 10kg of 1% neohesperidin dihydrochalcone solution for 10min, filter them, and spread the tortoise buds in the freezer In the material tray of the dryer;

[0042] 2) Set the freeze-drying program of the freeze-drying machine: first lower the temperature, 0~6h, -45°C, then raise the temperature, 6~12h, -45~-20°C, 12~24h, -20~20°C, to promote the tortoise flower The essential oil in the material dissolves during the freezing process. Five oil-water separation membranes with a pore size of 1nm are installed at the front end of the vacuum pump, and the essential oil and water in the material are extracted by vacuuming. The vacuum degree of the vacuum is -0.09~-0.1MPa. The membrane traps the oil phase inside the oil-water separation membrane, collects the oil phase and dehydrates to obtain 45.2mL of Toi Toi flower essential oil...

Embodiment 2

[0048] 1) Select 10kg of the above-mentioned fresh leaves of Taidai, wash them with purified water to remove dust and impurities, and then dry them, then soak them in 10kg of 3% neohesperidin dihydrochalcone solution for 15min, filter and spread the fresh leaves of Daidai In the material tray of the freeze dryer;

[0049] 2) Set the freeze-drying program of the freeze-drying machine: first lower the temperature, 0~6h, -40°C, then raise the temperature, 6~12h, -40~-20°C, 12~24h, -20~20°C, to promote the drying of the leaves. The essential oil in the material dissolves during the freezing process. 15 oil-water separation membranes with a pore size of 2nm are installed at the front end of the vacuum pump suction port, and the essential oil and water in the material are extracted by vacuuming. The vacuum degree of the vacuum is -0.1MPa. The phase is trapped inside the oil-water separation membrane, and the oil phase is collected and dehydrated to obtain 42.2 mL of Toi Toi leaf ess...

Abstract

The invention discloses a preparation method of citrus aurantium essential oil, hydrolat and fruit tea. The preparation method comprises the following steps: 1) pretreating selected citrus aurantium flowers / leaves / fruits, and spreading the pretreated citrus aurantium flowers / leaves / fruits in a material tray of a freeze dryer; 2) cooling the freeze dryer to-20 DEG C to-45 DEG C to enable essentialoil in the citrus aurantium flowers / leaves / fruits to be dissolved out in the freezing process; heating to 20-40 DEG C, vacuumizing to extract essential oil and water, intercepting an oil phase at theinner side of an oil-water separation membrane through the oil-water separation membrane, collecting the oil phase, refining to obtain citrus aurantium flower / leaf / fruit essential oil, collecting a water phase to prepare citrus aurantium flower / leaf / fruit hydrolat, and drying citrus aurantium flower / leaf / fruit residues to prepare citrus aurantium flower / leaf / fruit tea. According to the preparationmethod of the citrus aurantium essential oil, the hydrolat and the fruit tea, the essential oil, the hydrolat and the tea are obtained at the same time through a purely physical method, the originalfragrance and effects of citrus aurantium flowers, leaves and fruits are reserved, the process is simple, energy consumption is low, components of citrus aurantium are completely utilized and environmental pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation of plant essential oils and flower fruit tea, in particular to a method for preparing dai dai essential oil, pure dew and fruit tea. Background technique [0002] Daidai (Citrus aurantium L.cv.Daidai), also known as Huiqing Orange, Chunbulao, and Daidaiyuan, is a cultivated variety of the red-skinned lime in the Rutaceae Citrus lime. It is grown in Fujian, Sichuan, and Zhejiang in my country. Both are cultivated. Modern studies have shown that tortoise contains more than 200 biologically active ingredients, which can be used not only to treat digestive diseases, but also to strengthen the heart, diuretic, calm and reduce heart rate, relieve mental tension, and treat nervous system diseases such as epilepsy and circulatory systems such as high blood pressure. Disease has a certain effect. [0003] Toi Toi flowers, branches, leaves, and peels all contain essential oil, which is a better kind of...
