Abstract
The invention provides a method for rapidly extracting chili seed fatty acid, comprising the following specific steps of: collecting ripe chilies during a chili ripe period; drying the collected ripe chilies in a drying oven at a temperature of 60 DEG C; taking out chili seeds and crushing, and storing the crushed chili seeds at a temperature of 4 DEG C for future use; screening the stored chili seed powder by a 40-100-mesh sieve; packing the screened chili seed powder in a paper bag and placing the paper bag into the drying oven at a temperature of 105 DEG C to be dried; placing the paper bag into a small beaker and adding absolute ether to be higher than the paper bag; sealing the opening of the paper bag by a fresh-keeping film and carrying out ultrasonic auxiliary extraction under the conditions that the ultrasonic wave power is 40-80 W, the processing time is 10-80 min and the processing temperature is 10-60 DEG C; after the ultrasonic extraction, placing the paper bag into a Soxhlet extraction device and eluting the paper bag by the absolute ether on a water bath; adjusting the temperature of the water bath and adjusting time needed by primary backflow to be 8-10 min; and distilling and drying a mixed solution at the bottom of the Soxhlet extraction device to obtain crude extracts of the chili seed fatty acid.
Description
Technical field
The invention belongs to chilli seed deep processing and utilization field, be specifically related to a kind of separating and purifying method that from chilli seed, extracts lipid acid.
Background technology
Lipid acid is by carbon, hydrogen, three kinds of elementary composition compounds of oxygen, is the staple of neutral fat, phosphatide and glycolipid.Difference according to carbon chain lengths can be divided into short chain fatty acid, medium chain fatty acid and longer chain fatty acid with lipid acid again.And according to saturated and undersaturated different can lipid acid being divided three classes of hydrocarbon chain, that is: sfas (not having unsaturated link(age) on hydrocarbon), monounsaturated fatty acids (its hydrocarbon chain has a unsaturated link(age)) and polyunsaturated fatty (its hydrocarbon chain has two or two above unsaturated link(age)s).The fat that is rich in monounsaturated fatty acids and pufas composition at room temperature is in a liquid state, and is vegetables oil mostly.With the sfas is that the main fat of forming at room temperature is solid-state, is mostly animal tallow.Lipid acid is having under the situation of sufficient oxygen supply, the oxidable CO that is decomposed into
2And H
2O discharge significant amount of energy, so lipid acid is one of main energy derive of body.
Lipid acid human body grow with people's daily life in play an important role.Can lipid acid synthesize by body voluntarily can be divided into nonessential and necessary lipid acid.Non-essential fatty acid is that body can synthesize voluntarily, needn't rely on the lipid acid of provand, and it comprises sfas and some monounsaturated fatty acids.And that indispensable fatty acid is a human body health and lives institute is essential, but body oneself can not synthesize, and must rely on provand, and they all are unsaturated fatty acidss.It is essential that indispensable fatty acid is not merely nutrition institute, and with upgrowth and development of children with grow up healthy relevantly, reducing blood-fat is more arranged, prevents and treats therapeutic action such as coronary heart disease, and certain relation is arranged with physiological functions such as intelligence growth, memories.Simultaneously, lipid acid also can be used for the emulsifying agent and other tensio-active agent, lubricant, gloss-imparting agent in the styrene-butadiene rubber(SBR) production; And the midbody that is used to produce senior perfumed soap, transparent soap, Triple Pressed Stearic Acid and various tensio-active agents.
Capsicum Solanaceae Capsicum crop is global vegetables and processing and seasoning article.There is profuse capsicum resource in China, produces the half the of the approaching whole world of red pepper per year.Discover that chilli seed accounts for the heavy 30%-40% of full dried fruit, lipid content is suitable with soybean fat content in the chilli seed, and contains multiple lipid acid, and wherein linoleic content is the highest, and linolic acid is the indispensable fatty acid of human body, has very important nourishing function.
Soxhlet extraction is the classical way of the determination of fat, but has long, problem such as solvent consumption is big, extraction efficiency is low of extraction time.UW has the double attribute of fluctuation and energy, can effectively improve greasy extraction yield, and the grease that has been widely used in various crop at present extracts.So far, less about the process for extracting report of chilli seed lipid acid.Therefore, how to overcome the deficiency of soxhlet extraction, setting up optimum response system efficient, chilli seed lipid acid extraction fast is the difficult problem that urgent need solves in the chilli seed deep processing research work.
Summary of the invention
The technical problem that solves:The rapid extracting method that the purpose of this invention is to provide a kind of chilli seed lipid acid.This method can be used for the acquisition of chilli seed deep processing and specific unsaturated fatty acids, also for the lipid acid of other crops reference is provided.
Technical scheme:A kind of rapid extracting method of chilli seed lipid acid, concrete steps are following:
1) in the capsicum ripening stage, the ripe haw of gathering to its oven dry, takes out chilli seed and pulverizes in 60 ℃ of following baking ovens, stores for future use under 4 ℃;
2) the chilli seed powder of deposit is crossed 40 ~ 100 mesh sieves, be loaded in the paper bag, place 105 ℃ of baking ovens dry;
3) place small beaker to add anhydrous diethyl ether paper bag, make it to surpass the paper bag height, preservative film seals, and is 40 ~ 80W at ultrasonic power, and the treatment time is 10 ~ 80 minutes, and treatment temp is to carry out ultrasonic-assisted extraction under 10 ~ 60 ℃ the condition;
4) after the supersound extraction, paper bag is placed the Suo Shi extraction element, anhydrous diethyl ether carries out drip washing to paper bag, in water-bath, carries out, and regulates bath temperature, and making the required time that once refluxes is 8-10min;
5) Suo Shi extraction element bottom mixing solutions is distilled, dries and be chilli seed lipid acid crude extract.
Optimum condition is following: mesh screen is 60 ~ 100 orders, and ultrasonic power is 50 ~ 70W, and the treatment time is 20 ~ 40 minutes, and treatment temp is 20 ~ 40 ℃.
Beneficial effect:The invention provides a kind of method of fast, efficiently utilizing chilli seed to extract lipid acid for starting material.Its process is earlier chilli seed to be ground, and on the basis of Suo Shi extraction lipid acid, by means of UW, comes fast, efficiently to obtain lipid acid in conjunction with different ultrasonic power, supersound process time and treatment temp.
