Abstract
The present invention relates to a method for extracting and preparing pectin with high quality from the peel of the citrus class, such as orange peel, etc. The compound water solution of inorganic sulfur is used for soaking raw materials, such as treated orange peel, etc., and macroporous absorption resin and weak acidic cation exchange resin are used for decolorizing and refining liquid pectin; thus, the powder pectin with high quality, which has the characteristics of light color, low ash content, gelation degree of 150 to 200 DEG, is obtained.
Description
The invention belongs to a kind of method of from orange peel, obtaining through refining pectin.
From citrous fruit peel, obtain through refining pectin, nearly all adopt people's such as Lu Pei rock and Yang Dachuan general method (Food science, nineteen eighty-three o. 11th P22-26 and P34-39), with citrous fruit peel chopping,, remove water-soluble substanceses such as sugar in the pericarp, organic acid, pigment with hot and cold (50-60 ℃) water pretreatment, use inorganic acid solution then, pectin is carried in heating under agitation, removes by filter undissolved skin slag with whizzer etc. again, just can obtain liquid pectin; This glue with decolorizing and refinings such as gacs, through operations such as concentrated, precipitation, drying, pulverizing, just can be obtained Powdered finished product pectin again.
The finished product pectin that adopts above-mentioned general method to obtain through refining, degree of gelation is low, the ash content height, technology quality index does not reach requirement.Yield is lower simultaneously, and cost is higher, and the liquid pectin decoloration is made with extra care when filtering very difficult.
The objective of the invention is at above-mentioned existing problems, adopt the compound water solution of inorganic sulfur to soak raw material and with the method for macroporous adsorbent resin and weakly acidic cation-exchange resin decolorizing and refining liquid pectin, it is refining to save activated carbon decolorizing, solve the problem of filtration difficulty, thereby reach the reduction ash oontent, every technology quality index of pectin such as raising pectin grade, and improve glue yield and the cost that reduces finished product pectin.
Technology method of the present invention is, with the orange peel raw material that has shredded, pre-treatment is good, with accounting for the 0.1-50% (volume ratio) that always adds the acid amount, the compound water solution that is preferably the inorganic sulfur of 1-30% soaks, then with mineral acid regulate acidity reach needed pH value or with the compound of required inorganic sulfur and mineral acid add together pre-treatment good, and called in the orange peel raw material of the required water yield, under agitation heating hydrolysis extracts pectin.Then, remove by filter the skin slag with terylen cloth or whizzer, the pectin solution that obtains after the essence filter was handled 20-30 minute and (the liquid pectin: resin=100: 5-25 (weight ratio)) of realization decolorizing and refining with macroporous adsorbent resin and weakly acidic cation-exchange resin.After concentrate, precipitation, drying, crushing screening etc. then can obtain lighter color, degree of gelation is high Powdered finished product pectin.
Compared with the prior art the present invention has following characteristics:
1, the pectin obtained through refining of the present invention is high quality pectin, and color and luster is greyish white, and degree of gelation is 150-200 °, ash content＜2%, weight loss on drying＜10%, PH=2.8 ± 0.2, arsenic content＜0.0002%, heavy metal content＜0.0008%.
2, work simplification of the present invention is easy to operate, and glue yield can improve more than 10% than general salt acid system, and finished product pectin production cost reduces about 20%.
3, the finished product pectin powder that the present invention obtained through refining is stored steady quality, and sealing is stored in dry low temperature environment 1 year, and the degree of gelation reduction is less than 7%.
4, the finished product pectin that the present invention obtained through refining can be widely used in foodstuffs industry, medicine industry and the light industry cosmetic industry.
Facilities and equipments of the present invention are conventional equipment.
Embodiment:
Restrain dry orange peel through the hot water rehydration with 100, chopping, hot-water soak, the flowing water rinsing is clean, filter adds 1500 ml deionized water after doing, according to accounting for the oxide water solution that the 1-30% that always adds the acid amount adds inorganic sulfur, then add small amounts of phosphoric acid and regulate acidity and reach about PH2.0, under agitation be heated to 88-95 ℃ of insulation hydrolysis in 40 minutes and extract pectin with hydrochloric acid.Then, allowance for bark slag, just can obtain liquid pectin with terylen cloth or whizzer filtration.Can in the skin slag, add 600 ml deionized water, carry glue more once.Press macroporous adsorbent resin and the filtration in 20-30 minute of weakly acidic cation-exchange resin treatment capacity that liquid pectin amount adds 5-25% (weight ratio), smart filter back just can obtain the light clarifying liquid pectin of color and luster.At last, through concentrate, alcohol precipitation, filter are done, dry, crushing screening then can obtain the Powdered finished product pectin of 13.5 grams.
Claims (2)
1, a kind of method of from orange peel, obtaining through refining pectin, comprise raw materials pretreatment, extract pectin, separations of glue slag, sol decolorizing and refining, concentrate, precipitation, drying, pulverizing process, it is characterized in that extracting the pectin operation and soak the good orange peel raw material of pre-treatment with accounting for the compound water solution that always adds acid amount 0.1-50% (volume ratio) inorganic sulfur, then add mineral acid and extract pectin, perhaps the compound of inorganic sulfur and mineral acid are added together pre-treatment good, and the orange peel raw material of the modulated good water yield in extract pectin; Liquid pectin decoloration refining step is used by liquid pectin amount 5-25% (weight ratio) adding macroporous adsorbent resin and weakly acidic cation-exchange resin processing 20-30 and is divided kind to realize.
2,, it is characterized in that the orange peel raw material is to use dry orange peel according to the method for claim 1.
