Description
Technical field
The present invention relates to food processing technology field.More particularly, the present invention relates to a kind of extraction process of food grade aloe pectin.
Background technology
Pectin, also known as pectinic acid, has good gelling and emulsifying stability, is widely used in the various fields such as food, medicine, daily use chemicals and weaving.In food service industry, pectin often by as jelling agent, thickening material, stablizer, suspension agent, emulsifying agent, flavouring synergistic agent, its demand also growing, the extremely favor of people.The major ingredient of food fibre is not only by pectin, and have in medicines and health protection good antibacterial, anticancer, anti-ageing, reduce blood fat, reduce the various health care functions such as blood sugar, hemostasis, treatment diabetes and fat-reducing, cause the concern of height in recent years equally in medical circle.In conjunction with domestic and international achievement in research in recent years, the report that employing acid-hydrolysis method extracts pectin in various raw material is more.The pectin yield that this method obtains is low, and Gel baits is unstable simultaneously, and the extraction simultaneously for food grade pectin requires that technology is higher.
Summary of the invention
An object of the present invention is to solve at least the problems referred to above, and the advantage will illustrated at least is below provided.
A further object of the invention is to provide a kind of extraction process of food grade aloe pectin, improves the yield of aloe pectin, also improves the degree of gelation of aloe pectin simultaneously.
In order to realize, according to these objects of the present invention and other advantage, providing a kind of extraction process of food grade aloe pectin, comprise the following steps:
Step one, aloe raw material is broken, 100:2-3 mixes with oxysuccinic acid in mass ratio, is layed on glass partition by mixed aloe raw material, and laying depth is 1-2cm, with the surrounding irradiation 20-30min of ultraviolet to glass partition;
Aqueous two-phase extraction agent is added in step 2, aloe raw material after treatment, obtain hybrid extraction material, aloe raw material wherein after process and the volume ratio of aqueous two-phase extraction agent are 1:15-20, described aqueous two-phase extraction agent by massfraction be 20% polyglycol solution and massfraction be the sodium sulfate of 20%, phase-splitting formed;
Step 3, hybrid extraction material to be dropped in mixing tank, mixing 9min, enter in standing tank afterwards, leave standstill 3-5 hour and be separated, the temperature controlling to leave standstill tank is 20-30 DEG C, and the inwall of described mixing tank and standing tank is coated with activated carbon coating, described mixing tank is connected with motor, described motor drives described mixing tank with three gear rotational speed, and rotate clockwise 3min with 3500r/min successively, 5000r/min rotates counterclockwise 3min and 2000r/min and rotates clockwise 3min;
Step 4, collection polyoxyethylene glycol phase, be separated aloe pectin with polyoxyethylene glycol, by spraying dry, obtain aloe pectin powder.
Preferably, described aloe raw material also through pre-treatment, removes the pulp in aloe raw material before fragmentation, retains aloe pericarp.
Preferably, in described step 4, aloe pectin adopts Ultra filtration membrane method with being separated of polyoxyethylene glycol, and ultra-filtration membrane used is polysulphones hyperfiltration membrane.
Preferably, spray-dired inlet temperature is 175-185 DEG C, and air outlet temperature is 80-100 DEG C.
Preferably, in described step 4, after aloe pectin is separated with polyoxyethylene glycol, with the ethanol of volume parts 95%, aloe pectin is cleaned 2-3 time.
Preferably, the aloe raw material in described step one comprises Aloe vulgaris, Aloe arborescens var. natalensis and the aloe sinensis that mass ratio is 1:2:1.
Preferably, have 2-5 screen cloth along its longitudinal spaced set in described mixing tank, the aperture of described screen cloth is 6-10cm, and described screen cloth is coated with active carbon layer.
The present invention at least comprises following beneficial effect:
1) adopt aloe pectin extraction process of the present invention, the yield of aloe pectin can reach about 25%, and after adding oxysuccinic acid, the degree of gelation of aloe pectin improves about 30%;
2) standing tank and mixing tank inwall scribble activated carbon coating, just can adsorb the pigment in pectin, save the bleaching process in later stage in sepn process, and the time that saves is with artificial;
3) ultraviolet irradiation, not only can to carry out disinfection sterilization to aloe raw material, simultaneously, through ultraviolet irradiation after aloe mixes with oxysuccinic acid, aloe pectin can be made to change the pectin of solubility into, instead of the step utilizing salt acidolysis pectin in traditional technology, due to the present invention's making is edible pectin, utilize edible oxysuccinic acid and ultraviolet, they remain can not have any body harm to human body, also there is the effect regulating pectin mouthfeel simultaneously, and traditional acidolysis employing is sulfuric acid and hydrochloric acid, later stage also needs to carry out wash-out to residual acid, prevent the residual of acid,
4), Ultra filtration membrane method is used not only can to remove pigment remaining in aloe pectin, and other the unnecessary composition in aloe, compared to distillation method, the activity of pectin is influenced less, the residue rate of aloe pectin is only 0.1-0.3% simultaneously, the high-throughout characteristic of polysulphones hyperfiltration membrane decreases the process time that aloe pectin extracts, and ultra-filtration membrane is what can be recycled simultaneously, economic environmental protection;
5) the hybrid extraction material, in mixing tank is according to clockwise, counterclockwise, rotate clockwise, rotating speed first increases rear reduction, increase the turbulivity of hybrid extraction material, make hybrid extraction material correspondence mutually in fully dissolve while fully contact with the wall of mixing tank and screen cloth, decolour more efficiently, decolouring degree can reach more than 98%, this than the separating effect carrying out rotating under same rotating speed by single direction and decolorizing effect all good.
Part is embodied by explanation below by other advantage of the present invention, target and feature, part also will by research and practice of the present invention by those skilled in the art is understood.
