Abstract
A kind of pea hydroxypropyl carboxy methyl starch and preparation method belong to converted starch production technology；The starch is made of 90-100 parts of pea starch, 35-45 parts of sodium hydroxide, 400-600 parts of 86% isopropanol, 25-35 parts of propylene oxide, 30-35 parts of monoxone, 20-25 parts of phosphorylated ligand 5 in parts by weight, obtains product by mixing, heating, constant temperature, stirring and separation of solid and liquid in reaction kettle, washing；The present invention uses and realizes pea starch production pea hydroxypropyl carboxy methyl starch, formula and preparation method are simple, scientific, reasonable, the physical characteristics such as converted starch product strength, toughness, glossiness and transparency are good, product stability in use, safety, the feature of environmental protection, reliability are excellent, are especially able to satisfy and adapt to Capsules production and application.
Description
Technical field
The invention belongs to converted starch production technology, a kind of pea hydroxypropyl carboxy methyl starch and preparation side are related generally to
Method.
Background technique
Currently, various converted starches occur like the mushrooms after rain, but its quality good and the bad is not in domestic converted starch industry
Together, huge puzzlement is brought to numerous wasters in use.To find out its cause, a kind of adaptability, safety, steady can not be found
There is the raw material of huge advantage in terms of the qualitative, feature of environmental protection and reliability.
In recent years, (including content of starch, protein content, microelement the study found that property possessed by pea starch
Equal ingredients) be very suitable to production converted starch, and itself property brings many conveniences to application, as pea converted starch at
Film properties are superpower, and pea converted starch film smoothness and transparency are excellent, are particularly suitable for production starch hollow capsule.
Based on such situation, there is the pea hydroxypropyl carboxy methyl starch of stable, health, environmental protection using pea starch production
Have become current important research direction.But there are no research and development of products successes up to now.
Summary of the invention
The purpose of the present invention is to the above-mentioned problems of the prior art to grind in conjunction with the actual needs of production and application
Study carefully and design a kind of pea hydroxypropyl carboxy methyl starch and preparation method, it is stable, safe and environment-friendly, reliable to reach starch product performance
Purpose.
The object of the present invention is achieved like this:
A kind of pea hydroxypropyl carboxy methyl starch, the pea hydroxypropyl carboxy methyl starch is in parts by weight by following composition
Composition: 90-100 parts of pea starch, 35-45 parts of sodium hydroxide, 86% 400-600 parts of isopropanol, 25-35 parts of propylene oxide, chlorine
30-35 parts of acetic acid, 20-25 parts of phosphoric acid.
Hydroxypropyl carboxy methyl starch preparation method, preparation step are as follows:
1., in constant temperature stirred autoclave, disperse pea starch in 86% aqueous isopropanol in proportion, be warming up to 40
DEG C, it is proportionally added into sodium hydroxide, 40 DEG C of constant temperature stir 1.5-2.0 hours；
2., propylene oxide is added into reaction kettle in proportion, be heated to 45 DEG C, constant temperature, stirring 1.5-2.0 hours；
3., be added monoxone into reaction kettle in proportion, 45 DEG C of constant temperature, stirring 1.5-2.5 hours；
4., be added phosphoric acid into reaction kettle in proportion, regulation system pH value is 7, separates solid-liquid system with centrifuge, uses
86% isopropanol dries to obtain pea hydroxypropyl carboxy methyl starch after washing three times.
The present invention for the first time using and realize pea starch production pea hydroxypropyl carboxy methyl starch, formula and preparation side
Method is simple, science, rationally, and it is good to produce the physical characteristics such as converted starch intensity, toughness, glossiness and the transparency of preparation, starch
Stability in use, safety, the feature of environmental protection and reliability are excellent, are especially able to satisfy and Capsules is suitble to produce and use.
Specific embodiment
Embodiment of the present invention is described in detail below.
A kind of pea hydroxypropyl carboxy methyl starch, the pea hydroxypropyl carboxy methyl starch is in parts by weight by following composition
Composition: 90-100 parts of pea starch, 35-45 parts of sodium hydroxide, 86% 400-600 parts of isopropanol, 25-35 parts of propylene oxide, chlorine
30-35 parts of acetic acid, 20-25 parts of phosphoric acid.
Pea hydroxypropyl carboxy methyl starch preparation method, preparation step are as follows:
1., in constant temperature stirred autoclave, disperse pea starch in 86% aqueous isopropanol in proportion, be warming up to 40
DEG C, it is proportionally added into sodium hydroxide, 40 DEG C of constant temperature stir 1.5-2.0 hours；
2., propylene oxide is added into reaction kettle in proportion, be heated to 45 DEG C, constant temperature, stirring 1.5-2.0 hours；
3., be added monoxone into reaction kettle in proportion, 45 DEG C of constant temperature, stirring 1.5-2.5 hours；
4., be added phosphoric acid into reaction kettle in proportion, regulation system pH value is 7, separates solid-liquid system with centrifuge, uses
86% isopropanol dries to obtain pea hydroxypropyl carboxy methyl starch after washing three times.
