A kind of antistaling tablet for grapes that adopts the direct compression of full-powder method to produce
(1) technical field
The invention belongs to the fruit and vegetable fresh-keeping agent process technology, particularly a kind of antistaling tablet for grapes that adopts the direct compression of full-powder method to produce.
(2) background technology
The application of grape fresh-keeping method depends on the characteristic of effective ingredient pyrosulfite or bisulfites.
Its principle is shown as shown in the formula letter:
Water is main " startup agent ", meets the water chemistry balance and moves right, and discharges SO
2, press down mould sterilization, strengthened the storage property of grape.In the grape storage environment, because humidity ratio is bigger, this condition of water possesses all the time.
In order to control SO
2Release and be convenient to carry out compressing tablet, when making antistaling tablet for grapes, added different auxiliary materials respectively.As: Chinese patent CN1359627A, CN1091354C, C741099833C etc.Disclosed antistaling tablet for grapes in these documents owing to the problem of employed slow-release material and excipient in the component that constitutes antistaling tablet, causes it can not adopt the direct compression of full-powder method to produce antistaling tablet for grapes, and can only use the film-making of particle pressed disc method.With particle pressed disc method compacting antistaling tablet for grapes, fusing earlier, granulation, compressing tablet again; Time-consuming, take can, expense factory building, expense equipment, also lose effective ingredient.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art a kind of available full powder stock is provided, with the antistaling tablet for grapes of rotary tablet machine direct tablet compressing, this invention has solved in the past antistaling tablet for grapes in a large amount of production, heat the problem of compressing tablet of granulating again earlier, thereby overcome problem time-consuming in the prior art, that expense can, be taken factory building, expense equipment and loss effective ingredient.
Technical scheme of the present invention is as follows:
By weight percentage, antistaling tablet for grapes is made up of following composition:
A, effective ingredient: pyrosulfite or bisulfites 74-94%
B, slow release framework material 5-13%
C, be suitable for the excipient 1-13% of direct tablet compressing.
Pyrosulfite is sodium pyrosulfite, potassium metabisulfite or their mixture; Bisulfites is sodium hydrogensulfite, potassium bisulfite or their mixture.
The slow release framework material comprises:
(A), reduce the material of dissolution rate:
A, erodible skeletal substance---(1) wax class, as: Chinese wax, beeswax, paraffin, Ka Naba wax, (2) fats, as: one or both in stearic acid, glycerin monostearate, sucrose list (two) stearate, butyl stearate, the hydrogenated vegetable oil; Perhaps,
B, hydrophilic colloid skeletal substance---(1) cellulose family, as: methylcellulose, sodium carboxymethylcellulose, hydroxypropyl methylcellulose, (2) resinae, as: polyvinylpyrrolidone, one or both in the carboxylic polrvinyl;
(B), reduce the material of diffusion velocity, be insoluble skeletal substance---(1) resinae, as: polyethylene, polyvinyl chloride, polyvinylacetate, polymethacrylates, acrylic resin II number, (2) cellulose family, as: one or both in microcrystalline cellulose, the ethyl cellulose.
Be suitable for the excipient of direct tablet compressing, comprise:
(A), one or both in lubricant---talcum powder, calcium stearate, dolomol, the high melting-point wax;
(B), one or both in glidant---magnesia, gel aluminum hydroxide, calcium monohydrogen phosphate, the superfine silica gel powder.
Above-mentioned raw materials pulverized in proportion mix; Use the direct compression of full-powder method, use the rotary tablet machine compressing tablet to get final product.
Compared with prior art, the invention has the beneficial effects as follows: the fresh-keeping function of 1, having optimized antistaling tablet for grapes: make the SO in the antistaling tablet for grapes
2Stable release 6-8 month, and SO
2Percentage composition descends about 7% month by month: according to conventional preservation technique and using method, when using dosage was 2 ‰ of grape weight-4 ‰, the drug effect phase can reach 6-8 month.2, realized with direct compression of full-powder method large-scale production antistaling tablet for grapes.Save operations such as fusing, granulation, save time, economize and can, economize factory building and equipment, reduced the raw material heat loss, reduced cost.
(4) description of drawings
Fig. 1: the direct compression of full-powder method is produced the technological process of antistaling tablet for grapes.
Among the figure: 1, pyrosulfite or bisulfites 2, the material 3 that reduces dissolution rate, the material 4 that reduces diffusion velocity, lubricant 5, glidant 6, low-temperature grinding 7, weigh 8 respectively, mix 9, stir 10, compressing tablet 11, tablet quality check 12, packing.
(5) specific embodiment
Embodiment 1:
Prescription: sodium pyrosulfite 86%; Paraffin 10%: polyethylene 2.5%; Calcium stearate 0.5%; Gel aluminum hydroxide 1%.(polyethylene, M=1.8 ten thousand ~ 3.5 ten thousand).
Technology: earlier the material paraffin 2 that reduces dissolution rate is carried out low-temperature grinding 6, to 60 orders; Sodium pyrosulfite 1, the material polyethylene 3 that reduces diffusion velocity, lubricant stearic acid calcium 4, glidant gel aluminum hydroxide 5 are directly chosen more than 60 orders.Above-mentioned raw materials is weighed 7 respectively, and the back mixes 8, stirs 9 again, makes the bulky powder raw material, can flow freely, and angle of repose≤45 ° are used rotary tablet machine direct tablet compressing 10 then, through tablet quality check 11, pack 12 at last.
The technology of following examples is substantially with example one.
Embodiment 2, prescription: potassium metabisulfite 80%; Polyvinylpyrrolidone 3%; Acrylic resin II number 10%; Dolomol 1%; Calcium monohydrogen phosphate 6%.(polyvinylpyrrolidone, M=about 40,000; Acrylic resin II number, M=about 13.5 ten thousand).
