Description
Technical field
The invention belongs to biologies to extract, and in particular to a method of high degree of gelation pectin is extracted from the pomelo peel of Pingshan.
Background technique
Pingshan shaddock is Rutaceae evergreen fruit trees, has cultivation on China Guangdong, Fujian and other places.A large amount of shaddocks in actual production
Skin (account for about shaddock quality 30%) is not fully used, and the serious wasting of resources and environmental pollution are caused.Business at present
Upper common pectin extraction raw material are apple pomace, orange peel, megasse etc..Apple pomace and orange peel are mainly derived from fruit juice production
By-product industry, freshness date is short, easily corrupt, generates a large amount of microorganisms, then generates a large amount of pectases, carries out to pectin in itself
Degradation, greatly reduces the yield of subsequent pectin extraction, the especially yield of high molecular weight pectin.Megasse is mainly derived from
The by-product of beet-sugar factory sugaring.Beet-sugar factory sugaring beet used was just opened before the Sugar―beet biology maturity period
Begin harvest, beet simultaneously prematurity itself, and the pectin in immature beet is mainly protopectin, not soluble in water, increases and mentions
Take difficulty.And the mentioned pectin molecule amount of three is all smaller, it is difficult to reach the requirement of high degree of gelation.Shaddock as it is a kind of it is common can
Feeding habits fruit, long shelf-life are not easy to decay, and pectin content is apple, more than twice of citrus pulp in pomelo peel, is to extract pectin
Very good material.And the pomelo peel that the present invention uses is derived from mature Pingshan shaddock.Pingshan shaddock shaddock ped is thicker, resistance to storage
Fortune, long shelf-life is for three months, and shaddock is not easy to decay rotten, and contained pectin is mostly soluble pectin in shaddock ped.And
The early-maturing variety of Pingshan shaddock category high and stable yield, source is sufficient, is less prone to the problem of source shortage.
Pectin is a kind of polysaccharide polymer extracted from plant tissue, it is generally recognized that by protopectin, pectinic acid and fruit
Glue acid composition.Its basic structure is D- galactopyranosyluronic with a- (Isosorbide-5-Nitrae)-glycosidic bond links line style long-chain, average molecular
Amount is 1~400,000.Pectin is white or light-colored powder, odorless, hot strong, is practically insoluble in the organic solvents such as ethyl alcohol, water-soluble
Liquid is sticky, weakly acidic, more stable than under alkaline condition in acid condition, can be formed with various metals ion under certain condition
Flocculent deposit.The common method for extracting pectin has classical acid formulation, ion-exchange, microwave method, ammonium oxalate method etc..
Pectin is in food-processing industry and chemical engineering industry, frequently as thickener, stabilizer, emulsifier, gelling agent and group
Knit modifying agent.A kind of excellent pharmaceutical preparation matrix on field of medicaments, have antibacterial, detumescence, hemostasis, removing toxic substances, antidiarrheal,
Blood pressure lowering and it is anti-radiation the effects of.
The traditional extraction process of pectin is sour formulation, but sour formulation makes pectin be in the environment of high temperature, highly acidity for a long time
Under, make α-Isosorbide-5-Nitrae glycosidic bond fracture in pectin, causes the molecular weight of pectin to reduce, degree of gelation reduces.
Enzymatic Extraction pectin decomposes complex polysaccharide using the selectivity of enzyme, pectin is released, the method is easy to operate,
Environmental protection, but the cost of enzyme is excessively high, greatly improves production cost, is unfavorable for the implementation of industrialization.
The basic principle of metal-chelator method is to form Calcium Pectate using the calcium ions and magnesium ions in chelating agent and protopectin to sink
It forms sediment, so that pectin molecule is released, extraction soluble in water.Chelate method extraction conditions are mild, mentioned pectin molecule amount compared with
Greatly, to have good gelling.But single chelate method institute elapsed time is too long, and the addition for crossing Polychelants causes fruit
The increase of ash content in glue finished product, it is difficult to remove.
Common metal chelating agent has calgon, ammonium oxalate etc. in pectin extraction.Calgon energy and plant tissue
Middle calcium ions and magnesium ions form aqueous precipitation, release the sealing process of pectin, still, even the calgon of food-grade,
In still have micro heavy metal lead, arsenic etc..Arsenic can cause skin pigment depigmentation, angling, canceration etc., and lead can then hide in people
In body body, long-term consumption easily causes lead poisoning.The calgon of food-grade is low dense there are also the fluoride of certain content
The fluoride of degree can cause slow poisoning and fluorosis of bone, cause damages to human health.Too low concentration is difficult to release fruit completely
The sealing process of glue, excessively high concentration can cause potential hazard to human body again.Therefore the usage amount of calgon needs to carry out
Stringent control limits its application in pectin extraction.
Ammonium oxalate is also the metal-chelator for showing extraction pectin common in the literature, and ammonium oxalate can be formed with calcium ions and magnesium ions
Water-insoluble precipitating, reduces the content of pectin in extracting solution.Time-consuming for single ammonium oxalate extraction, and efficiency is not also high.And grass
Sour ammonium inherently has toxicity, and heat easily resolves into oxalic acid and ammonia.And temperature is a critically important factor when pectin extraction,
Pectin extraction typically carries out at high temperature, and the labile feature of ammonium oxalate heat hinders its combination with other methods,
Can actual operation it is not strong.
EDTA can be chelated with a variety of bivalent metal ions, be a kind of excellent calcium ions and magnesium ions chelating agent.EDTA can be effectively
Calcium ions and magnesium ions are released to the sealing process of pectin, form aqueous precipitation, precipitate component is mainly its calcium and magnesium metal salt, calcium and magnesium
Metal salt is substantially nontoxic to human body.EDTA stable structure, is soluble in hot water, can effectively with other extracting method combined extracting fruits
Glue reduces extraction time, improves pectin yield, guarantees that the pectin of macromolecule is not degraded, and by chelation, improves fruit
The molecular weight of glue then improves the viscosity and gel strength of pectin.
Ultrasonic method is to be now widely used for a kind of method of natural product extraction.It is strong that it mainly utilizes ultrasonic wave to generate
The multistage effect such as cavitation effect, mechanical effect, accelerate the release of intracellular active principle.But with the intensity of ultrasonic wave and when
Between increase, the side chain of pectin degrades, and molecular weight can gradually decrease influence pectin grade, therefore be unfavorable for high degree of gelation
The extraction of pectin.
Microwave method is a kind of common assisted extraction method.Microwave refer to wavelength 1mm between 1m, frequency is in 300MHz
To the electromagnetic wave between 30000MHz.On the one hand it is that high-frequency electromagnetic penetrates spe medium that microwave abstracting is microwave radiation process, is arrived
Up to inside material, lead to the broken dissolution of material.Electromagnetic field caused by another aspect microwave, it is molten to extracting that acceleration is extracted part
Agent interface diffusion rate improves extraction efficiency.Microwave abstracting have many advantages, such as rapidly and efficiently, homogeneous heating, be widely used in natural
In the extraction of substance.But continuous microwave extraction, which is difficult to control, extracts system temperature, and system temperature rises at a high speed always, makes pectin
Molecule is constantly in the state of vibration at high speed heat production, and glycosidic bond is caused to be broken, and pectin is degraded.And batch microwave rule can be fine
Control extraction system temperature in a certain range, in due course reduce extract system temperature, prevent glycosidic bond or branch in pectin
Fracture, keep the structural integrity of pectin.
