Abstract
The invention discloses a preparation process of pectin, which includes the steps of: (1) weighing a certain amount of pear residue and placing the pear residue in a conical container, adding a 4 mol/L hydrochloric acid solution into the conical container, wherein mass ratio of the hydrochloric acid to the pear residue is 15-16:1, and uniformly mixing the components; (2) heating the conical container filled with the hydrochloric acid and the pear residue in a water bath pot at 88-92 DEG C for 0.8-1.2 h; (3) after the components is heated completely, performing suction filtration to the conical container through a suction filter while hot to prepare a pear residue acid liquid; (4) adding 95% ethanol to the pear residue acid liquid at equal volume, stirring the liquid, and allowing the liquid to stand for 2.5-3 h to prepare a pectin precipitate; and (5) separating the pectin precipitate through a centrifugal separator, drying the pectin precipitate in a drying box for 3-5 h at 65 DEG C to prepare the pectin. In the method, the pear residue waste is recycled, so that environment load is reduced. The method has simple processes and is highly effective.
Description
Technical field
The present invention relates to a kind of pectin reparation technology, is applied to pears slag reutilization technology field.
Background technology
The pectin overwhelming majority is used for food industry, using its gelation production jelly, fruit jam and soft sweet, some use
In medicine aspect as hemorrhage and plasma substitute, moreover it is possible to for treating diarrhoea with noble metal poisoning, demand of the whole world to pectin
Amount increasingly increases, and Chinese pectin production ability far can not meet the demand of the country, needs in a large number from foreign import.And in pears slag
Containing pectin, China's pear tree Planting household is various, when being processed to pear, produces many pears slags, and these pears slags are most of to be made
It is disposed off for rubbish, load is caused to environment, therefore pectin is produced out with very high prospect from pears slag.
The content of the invention
It is above-mentioned to solve the problems, such as, the invention discloses a kind of pectin reparation technology, comprises the steps of：
Step one：Weigh a certain amount of pears slag to be placed in conical vessel, concentration is then added into conical vessel for 4mol/L's
Hydrochloric acid solution, hydrochloric acid is 15 ~ 16 with the mass ratio of pears slag:1, mix homogeneously；
Step 2：Will be equipped with hydrochloric acid and be placed in 0.8 ~ 1.2h of heating in the water-bath that temperature is 88 ~ 92 DEG C with the conical vessel of pears slag；
Step 3：After the completion of heating, while hot conical vessel is obtained into pears slag acid solution by sucking filtration machine sucking filtration；
Step 4：The ethanol that isopyknic concentration is 95% is added in pears slag acid solution, 2.5 ~ 3h of standing obtains final product pectin and sinks after stirring
Starch；
Step 5：By pectin precipitate after centrifugal separator separation, pectin is put in drying baker and is dried 3 ~ 5h, temperature sets
65 DEG C are set to, pectin is obtained final product.
The technical program is adopted, the invention has the beneficial effects as follows：By pears slag recycling, reduce it and environment is born
Lotus, while technological process is simple, it is easy to operate, improve the interests of enterprise.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
Embodiment one：

Step 2：Will be equipped with hydrochloric acid and be placed in heating 1h in the water-bath that temperature is 90 DEG C with the conical vessel of pears slag；
Step 3：After the completion of heating, while hot conical vessel is obtained into pears slag acid solution by sucking filtration machine sucking filtration；
Step 4：The ethanol that isopyknic concentration is 95% is added in pears slag acid solution, 2.5h is stood after stirring and is obtained final product pectin precipitation
Thing；
Step 5：By pectin precipitate after centrifugal separator separation, pectin is put in drying baker and is dried 5h, temperature setting
For 65 DEG C, pectin is obtained final product.
Embodiment two：
The invention discloses a kind of pectin reparation technology, comprises the steps of：
Step one：Weigh a certain amount of pears slag to be placed in conical vessel, concentration is then added into conical vessel for 4mol/L's
Hydrochloric acid solution, hydrochloric acid is 15 with the mass ratio of pears slag:1, mix homogeneously；
Step 2：Will be equipped with hydrochloric acid and be placed in heating 1.1h in the water-bath that temperature is 89 DEG C with the conical vessel of pears slag；
Step 3：After the completion of heating, while hot conical vessel is obtained into pears slag acid solution by sucking filtration machine sucking filtration；
Step 4：The ethanol that isopyknic concentration is 95% is added in pears slag acid solution, 3h is stood after stirring and is obtained final product pectin precipitation
Thing；
Step 5：By pectin precipitate after centrifugal separator separation, pectin is put in drying baker and is dried 5h, temperature setting
For 65 DEG C, pectin is obtained final product.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention
Scheme；Therefore, although this specification with reference to each above-mentioned embodiment pair present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent；And all without departing from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
