Abstract

본 발명은 생전분 또는 생전분질 입자를 기능성과 반응성을 증대시키기 위하여 보다 적은 미세입자로 단편화시키는 새로운 미세입자 전분의 제조방법에 관한 것으로서 전분 분해효소의 침식작용과 고형 매체의 분쇄마찰작용을 동시에 상호보완적으로 이용하여 견고한 구조를 가지고 있는 생전분 또는 생전분질 입자를 고효율로 단편화시키는 것이다.The present invention relates to a method for preparing new microparticle starch, in which raw starch or biostarch particles are fragmented into fewer microparticles in order to increase their functionality and reactivity. Complementary use to fragment the raw starch or raw starch particles having a solid structure with high efficiency.

즉 생전분 또는 생전분질 입자를 수용액에 600g/ℓ 범위내로 현탁시키고, 현탁액에 글루코아밀레이즈, 알파아밀레이즈, 베타아밀레이즈, 풀루라네이즈, 아이소아밀레이즈, 그리고 사이클로텍스트린 글루카노트랜스퍼레이즈와 같은 전분 분해 효소와 세라믹구, 유리구와 같은 분쇄마찰효과를 줄 수 있는 고형매체를 첨가하여, 호화가 일어나지 않는 70℃이내에서 교반하면서 반응시켜 생전분 또는 생전분질 입자를 미세입자로 단편화시키는 것이다.That is, raw starch or raw starch particles are suspended in an aqueous solution in the range of 600 g / L, and in suspension, glucoamylase, alpha amylase, beta amylase, pullulanase, isoamylase, and cyclotextine glucanotransferase The same starch degrading enzyme and a solid medium capable of giving a crushing friction effect, such as ceramic spheres and glass spheres, are added and reacted while stirring within 70 ° C. where no gelatinization occurs. The raw starch or raw starch particles are fragmented into fine particles.

본 발명에 의하여 단편화된 미세 생전분 입자를 각 산업분야에 이용하면서 호화성, 용해성, 분산성, 안전성, 보수성, 침투성, 정착성, 투명성, 점도성등이 증가하고 고품질의 생붕괴성 플라스틱을 얻을 수 있는 등의 효과가 있다.The fine biostarch particles fragmented by the present invention are used in each industrial field to increase the gelatinization, solubility, dispersibility, safety, water retention, permeability, fixability, transparency, viscosity, etc., and to obtain high quality biodegradable plastics. It can be effective.
