Abstract
The invention provides an ultrasound-assisted tea oil extraction method. Tea seeds are used as raw materials and the ultrasound-assisted tea oil extraction method comprises the following steps of: harvesting and sorting tea seeds, drying, shelling and crushing, sieving, weighing, adding an extraction solvent, performing ultrasound-assisted extraction, separating, evaporating and recovering the solvent, and obtaining tea oil. The extraction process is simple, processing cost is low, extraction efficiency is high, and tea-oil tree resources can be fully utilized.
Description
Technical field
The present invention relates to the extracting method of tea oil, be specifically related to a kind of method of ultrasonic wave assisted tea oil extraction.
Background technology
Oil tea (Camellia oleifera Abel.) is the Theaceae Camellia Plants, originates from China, has long cultivation history, is and one of oil palm, olive and the coconut world equally celebrated for their achievements four large woody edible oil source seeds.Tea oil (Camellia oil) is the edible oil that the mature seed of plant of theaceae oil tea is obtained through squeezing, has another name called tea-seed oil, camellia oil, is the distinctive woody grease of China, and the reputation of " treasure in oil " is arranged from ancient times, and " east olive oil " laudatory title is more arranged.The content of unrighted acid in tea oil---oleic acid, linoleic acid plus linolenic acid is the hat of various edible vegetable oils up to 83%～95%.Tea oil contains vitamin E, vitamin D, vitamin K and carrotene.Tea oil also contains the bioactivators such as tsubakisaponin, Tea Polyphenols, squalene.
At present, the extraction grease generally has the methods such as milling process, extraction method or the first rear leaching of pre-press for extracting juice combine from oil plant.But milling process cake slag resid amount is high, and oil yield efficiency is low, and process for refining is loaded down with trivial details, and the lixiviation process crude oil is impure many, and east of oil is undesirable.Extraction research at present is more; but; the ultrasonic wave assisted extraction; especially the preparation method that extracts grease in large-scale production is actually rare; the hyperacoustic cavitation effect of invigoration effect main source that ultrasonic wave separates oil extraction, it can strengthen the mass transfer rate of extraction separation process, thereby is conducive to the extraction of grease; shorten extraction time, and can guarantee the quality of grease.
Do not adopt the method for ultrasonic wave assisted tea oil extraction in prior art.
Summary of the invention
The invention provides a kind of method of ultrasonic wave assisted tea oil extraction.The tea oil time that the method is extracted is short, and gained tea oil quality is high.
The technical solution used in the present invention is as follows:
A kind of method of ultrasonic wave assisted tea oil extraction is characterized in that, comprises the following steps:
(1) with tea seed under 40-60 ℃ of condition vacuum drying 1-2 hour;
(2) dried tea seed is shelled, pulverized the 40-50 mesh sieve;
(3) will pulverize rear raw meal drops in container, add extractant in container, mix, keep air-tight state, then the container that will fill feed liquid joins in ultrasonic extractor, extract 25-30min under room temperature condition, improve again temperature to 50-65 ℃, 30-60min is extracted in insulation, and wherein, the feed liquid mass volume ratio (g/mL) of extraction is 1: 4-12;
(4) after extraction finished, suction filtration was removed the slag dregs of rice, gets the suction filtration mixed liquor;
(5) with suction filtration mixed liquor centrifugation 15-25min under the condition of 2300-2800r/min, the gained supernatant is extract;
(6) with the supernatant extract rotary evaporator solvent removed by evaporation at reduced pressure of collecting, reclaim simultaneously solvent;
(7) at last the tea oil of desolventizing is carried out vacuum drying, get final products tea oil.
The method of described ultrasonic wave assisted tea oil extraction is characterized in that, the described extractant of step (3) is n-hexane.
The present invention has the following advantages:
(1) extraction process is simple, meets demand of industrial production;
(2) adopt the ultrasonic wave assisted extraction, shortened extraction time, improved efficient, method is reliable, and is stable;
(3) leaching process can omnidistancely be controlled, and is not subjected to the impact of natural environment
(4) owing to adopting the ultrasonic wave assisted extraction, avoided HTHP and harmful substance to the negative effect of tea oil Yield and quality, the intact preservation of the every nutritional labeling of gained tea oil.
The present invention is take tea seed as raw material, for the high efficiency extraction technique of tea oil provides theoretical foundation, development and the resource synthetic development utilization of camellia oleiferaindustry had positive facilitation.
The specific embodiment
Now take laboratory implementation as example, non-limiting examples is described below:
Tea seed is dry under 40-60 ℃ of vacuum condition, and then shell, pulverize.Get the raw meal after 200g pulverizes, add 600mL n-hexane extractant, keep air-tight state, feed liquid joins in ultrasonic extractor simultaneously, extract 30min under room temperature condition, then improve temperature to 55 ℃, 45min is extracted in insulation, after extracting end, suction filtration is removed the slag dregs of rice, obtains the suction filtration mixed liquor, centrifugal 20min under the condition of 2500r/min, gained supernatant are extract.With rotary evaporator reduction vaporization extract, reclaim solvent, obtain tea oil, then the tea oil that obtains is carried out vacuum drying, get final tea oil finished product.
The physical and chemical index contrast of ultrasonic auxiliary extraction method gained tea-seed oil
Claims (2)
1. the method for a ultrasonic wave assisted tea oil extraction, is characterized in that, comprises the following steps:
(1) with tea seed under 40-60 ℃ of condition vacuum drying 1-2 hour;
