Description
Technical field
The present invention relates to capsule filmogen preparation technical fields, and in particular to a kind of preparation side of high water-retaining type capsule
Method.
Background technique
Capsule has very extensive application in medicine, health care product and functional food industry, is present drug and function
One of energy most common dosage form of food.It is with good appearance, conducive to covering content drug odor, insulation blocking, fully absorbing,
Convenient for meeting positioning, delayed release requirement, many advantages, such as preparation process is simple, powder charge is easy to use.
The Capsules that present pharmaceutical factory uses mostly are using animal gelatin as raw material, and animal gelatin is mainly by animal osteoderm
In the gelatine, the hide glue that extract be made.Animal gelatin have the drawback that (1) gelatin molecule easily with formaldehyde, reduced sugar base class
The crosslinking of the drugs such as compound and vitamin C had not only influenced the disintegration of capsule but also had influenced the stability of drug;(2) gelatin quality is by dynamic
Object health status influences, and the edible animal sources gelatin with disease easily propagates pathogeny, causes cross-infection, causes food safety
Hidden danger;(3) its moisture content is higher, hygroscopicity is strong, and easily gives the water transport of absorption to content drug, becomes the drug moisture absorption
Matter causes drug quality unqualified or shortens validity period;(4) animal gelatin source is mostly that the skin of animal and bone pass through fermentation
, and it is added to a large amount of chemical component during the fermentation, serious pollution can be generated to air and water environment.
Starch capsule product is a kind of novel non-gelatin class capsule, has that safe and non-toxic, raw material sources are extensive, can be given birth to
The advantages that object is degraded.But since pure starch and single modified starch have the defects that in performance, such as: viscosity is high, film forming is poor, film
The features such as toughness is strong, poor water retention property, bad mechanical performance makes starch base capsule be difficult to compare favourably with animal gelatin capsule, together
When again be easy the moisture absorption, more demanding to preservation condition, the shelf-life is not grown.So although the patent about starch capsule is more,
The product that industrialized production can be formed is few.
Therefore, needing to develop a kind of capsule for being able to solve the above problem is highly desirable.
Summary of the invention
Present invention mainly solves the technical issues of, have the defects that film forming is poor, poor water retention property for current capsule, provide
A kind of preparation method of high water-retaining type capsule.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of preparation method of high water-retaining type capsule, it is characterised in that specific preparation step are as follows:
(1) water intaking tongue fur is put into steam-explosion jar, and steam is passed through into steam-explosion jar, until in steam-explosion jar pressure up to 2.2~2.4MPa,
After 30~40s of pressure maintaining, steam-explosion jar discharge valve is opened, is injected into material moment in steam-explosion jar in receiving tank, collected and receive
Material in tank obtains sphagna fiber;
(2) chloroacetic acid solution and isopropanol are obtained into mixed liquor after mixing, by above-mentioned sphagna fiber, mixed liquor and hydroxide
It is fitted into three-necked flask after sodium solution mixing, and is passed through nitrogen until displacing all air, in nitrogen protection into there-necked flask
Under, 30~40 DEG C are heated to, 30~40min is stirred, obtains the reactant containing etherificate sphagna fiber;
(3) pH to 4~5 that the above-mentioned reactant containing etherificate sphagna fiber is adjusted with hydrochloric acid, is filtered after standing 20~30min,
Filter residue is collected, is rinsed filter residue 2~3 times with anhydrous methanol, be removed inorganic salts and the chloroacetic filter residue of unreacted, puts it into
In baking oven, under conditions of temperature is 70~80 DEG C, dry 30~40min collects dried object, as etherificate sphagna fiber;
(4) above-mentioned etherificate sphagna fiber, potato starch natural plant gum, water are poured into glue pot, is 60~80 DEG C in temperature
Under the conditions of, 1~2h of insulated and stirred obtains mixture, then sorbierite is added into mixture, continues under conditions of 60~80 DEG C
Colloidal sol is obtained after 1~2h of heat preservation;
(5) above-mentioned colloidal sol is added in the glue bucket of Capsules manufacturing machine, glue temperature within the barrel is made with the cooling rate of 10 DEG C/min
1~2h is stood after being down to 40~60 DEG C, obtains Capsules, as high water-retaining type capsule.
The temperature of steam described in step (1) is 220~240 DEG C.
The mass ratio of chloroacetic acid solution described in step (2) and isopropanol is 3 ︰ 4, and the mass fraction of chloroacetic acid solution is
40%, the mass ratio of above-mentioned sphagna fiber, mixed liquor and sodium hydroxide solution is 2 ︰, 1 ︰ 1, and the mass fraction of sodium hydroxide solution is
20%。
The mass fraction of hydrochloric acid described in step (3) is 10%.
Above-mentioned etherificate sphagna fiber, potato starch natural plant gum described in step (4), water mass ratio be 1 ︰, 1 ︰ 2, sorb
The quality of alcoholic solution is the 10% of mixture quality.
Glue temperature within the barrel described in step (5) is 90~100 DEG C, 60~90min of constant temperature.
The beneficial effects of the present invention are:
Sphagna fiber is made by raw material of sphagna first in the present invention, then it is reacted under alkaline condition with monoxone, etherificate is made
Sphagna fiber will be put into Capsules manufacture after etherificate sphagna fiber, potato starch natural plant gum, water, sorbierite mixed sols
In machine, Capsules, as high water-retaining type capsule are made, the present invention is made first using sphagna as raw material through high steam explosion
Sphagna fiber, sphagna are all-natural products, and material is clean, without germ, and fiber surface contains great amount of hydroxy group, and hydroxyl has hydrophilic
Property, hydrone can be locked in fiber surface, play the role of shrink, water conservation, therefore its water retention property is good, its use can
The water-retaining property of capsule produced by the present invention is improved, monoxone and sphagna fiber carry out reacting obtained carboxymethyl sphagna in the presence of a base
Fiber, as etherificate sphagna fiber, etherificate sphagna fiber have the effects that film forming, gluing, water conservation, colloid protection, film forming
It is good, gluing shape liquid is formed after being dissolved in water, potato starch natural plant gum has water retention, and sorbierite is as adhesive, simultaneously
Also there is water retention, and it is not volatile polyalcohol, is good stabilizer, so that manufactured capsule water-retaining property is excellent
It is different and have good stability, it has broad application prospects.
