Abstract
With preparation of pectine by molecular sieve method.The present invention makes raw material with pectous plant, through the peracidity extracting, behind the aluminium salt precipitation method, must contain Al (OH)
3Pectin and aluminium complex thereof, further extract purifying by sieve method of the present invention, it is qualified to have obtained steady quality, the pectin dry product that flavour is pure.Because do not use the alcohol pectin of purifying in the method, thereby the cost of pectin is descended greatly, and preparation process technology is reasonable, equipment is simple, easily industrialization is fit to China's national situation.
Description
The invention belongs to the technical field of from plant material, extracting pectin.
At present, the common method of domestic and international industrial production pectin is aluminium (copper) salt precipitation method.In the technological process of this method purification pectin, per kilogram dry fruit glue need be with 100～200 kilograms alcohol, though in the process of aftertreatment recyclable alcohol, make the technological process of whole preparation pectin quite complicated, equipment is huge, the energy consumption height.China's alcohol amount lacks high price in addition, has caused the cost costliness of pectin, makes to be difficult to develop pectin food in China so far.A large amount of pectin productions of industrial urgent need press for a non-alcohol method road for preparing pectin.Simultaneously, prepare pectin with microbial method, its molecular weight of obtainable pectin is more than 200,000, and gamma value can reach more than 75%, but its method exists bacterial classification easily to degenerate, and variation causes pectin quality instability, and industrialization is had any problem.
The purpose of this invention is to provide a kind of preparation of pectine by molecular sieve method, it has, and production unit is simple, production technique is reasonable, does not use alcohol, and is with low cost, and can obtain steady quality, and qualified pectin is easy to suitability for industrialized production.
Preparation of pectine by molecular sieve method of the present invention, be to contain the plant material of protopectin-, through the acidic hydrolysis extracting, ion exchange method, microbial method or add the carbonaceous zeolite process and obtain pectin extract (I), extract (I) obtains containing Al(OH by the aluminium salt precipitation method), pectin and aluminium complex (II) thereof, intermediate (II) extracts purifying by sieve method, in intermediate product (II), add divalent calcium, magnesium salts, acid, its proportioning is in the 100 gram intermediate products (II), add 0.05-0.1 gram divalent calcium magnesium salts, 0.1-0.5mol acid, or in intermediate product (II), adding polysaccharide membrane-forming agent Type B, its proportioning is in the 100 gram intermediate products (II), adds polysaccharide membrane-forming agent Type B 10-110ml, in above-mentioned pectous mixture, formed the molecule screen cloth, allow it spray silk entry, in water, add basic salt, oxyhydroxide simultaneously, its proportioning is, water 1500-2000ml, basic salt 0-5mol, oxyhydroxide 0-3mol, or adding polysaccharide membrane-forming agent C type 0-120 gram, PH=3-14,5 minutes to 48 hours time, wet pectin forms the body that congeals, water rinse, oven dry promptly gets the pectin dry product.
In aforesaid method, used pectous plant material is a tangerine peel, citrus waste material, Sunflower Receptacle; Acid is hydrochloric acid, sulfuric acid, phosphoric acid, citric acid, tartrate; The divalent calcium magnesium salts is a calcium chloride, magnesiumcarbonate, sal epsom; Basic salt is a yellow soda ash, salt of wormwood, Trisodium Citrate, bicarbonate of ammonia, volatile salt; Oxyhydroxide is sodium hydroxide, potassium hydroxide, calcium hydroxide, ammonium hydroxide.
With the pectin face light yellow complexion that this law obtains, flavour is pure, and its specific targets can be: water content≤10%, and total gray scale＜7%, degree of gelation is 150 grades, lead tolerance≤1.9ppm, arsenic content＜0.5ppm, gamma value 74%, methoxyl group 13%, heavy metal≤18ppm.
It is reasonable to have technology with the pectin of sieve method of the present invention preparation, the advanced person, and equipment is simple, easily industrialization, owing to do not use the alcohol pectin of purifying, thus the cost of pectin is descended greatly, and constant product quality.
For the present invention is further understood, illustrate with following embodiment.
Embodiment
Get new fresh orange peel 500g, add the water of 1500ml and the hydrochloric acid of 30ml weight percent 35%, 74 ℃ of following extractings of temperature 90 minutes, get extract (I), the alum solution 2000ml and the 1%(weight that in extract (I), add 2% weight percent concentration) the volatile salt 1700ml of concentration, transfer PH=4.Press filtration must contain Al(OH), pectin and aluminium complex (II) thereof.Add polysaccharide membrane-forming agent Type B 25ml, mix making beating thoroughly, just can remove the aluminum ions while, in pectin, form the molecule screen cloth.Its spray silk entry, in water, add polysaccharide membrane-forming agent C type 2g simultaneously then.Stir half an hour, pectin has formed the body that congeals with molecular sieve function in water.Leach, 50 ℃ of oven dry down, the molecular sieve rack will be eliminated naturally, obtains the pectin dry product.
