Description

用乙醇溶剂制备不含交联化学键的非晶淀粉颗粒的方法 Method for preparing amorphous starch granules without crosslinking chemical bonds with ethanol solvent

技术领域technical field

本发明涉及一种非晶淀粉的生产方法，特别涉及一种用乙醇溶剂制备不含交联化学键的非晶淀粉颗粒的方法。The invention relates to a method for producing amorphous starch, in particular to a method for preparing amorphous starch granules without crosslinking chemical bonds by using ethanol solvent.

背景技术Background technique

淀粉是一种颗粒状天然高分子，由植物通过光合作用合成，其基本组成成分是碳水化合物，淀粉类产品主要指淀粉和变性淀粉。目前，尽管淀粉类产品的种类繁多，但从物态性质上都可以分成两大类，一类是同时具有结晶性和颗粒性的多晶颗粒态产品；另一类是既不具有结晶性又不具有颗粒性的非晶糊化态产品。Starch is a granular natural polymer synthesized by plants through photosynthesis. Its basic components are carbohydrates. Starch products mainly refer to starch and modified starch. At present, although there are many kinds of starch products, they can be divided into two categories in terms of physical properties. One is polycrystalline granular products that are both crystalline and granular; the other is neither crystalline nor granular. Amorphous gelatinized product without granularity.

处于这两类物态的淀粉及变性淀粉产品虽然已经被广泛地应用，但是，它们在结构和性质上仍存在较大缺陷。处于多晶颗粒态的淀粉同时具有结晶性和颗粒性，其优点是产品保持着淀粉原有的颗粒结构，容易分离、纯化、脱水、干燥及粉碎等后处理，可以生产高纯度的产品以满足食品、制药等行业的需要；其缺点在于含有大量的结晶结构使淀粉颗粒结构不均匀、渗透性差、吸附性低、化学反应活性与生物反应活性低、可加工性差，直接影响了产品的性能、制造成本和应用领域。Although starch and modified starch products in these two states of matter have been widely used, they still have relatively large defects in structure and properties. Starch in the polycrystalline granular state has both crystallinity and granularity. Its advantage is that the product maintains the original granular structure of starch, and it is easy to separate, purify, dehydrate, dry and pulverize. It can produce high-purity products to meet The needs of food, pharmaceutical and other industries; its disadvantages are that it contains a large amount of crystalline structure, which makes the starch granule structure uneven, poor permeability, low adsorption, low chemical reactivity and biological reactivity, and poor processability, which directly affects the performance of the product. Manufacturing costs and areas of application.

处于非晶糊化态的淀粉产品，具有非晶性，但不具有颗粒性，其优点在于只含有非晶结构，不含有结晶结构，其结构均匀、渗透性好、化学和生物反应活性高、可加工性好、易生物降解和消化吸收；其缺点在于淀粉原有的颗粒结构已经被破坏，导致产品难于甚至无法进行分离、纯化和干燥，无法生产高纯度的产品，直接影响该淀粉产品制造技术的发展、产品品种的增加以及应用领域的扩展。目前，只有预糊化淀粉等少数几种非晶糊化态淀粉产品生产。Starch products in an amorphous gelatinized state are amorphous but not granular. Its advantages lie in that it only contains an amorphous structure and does not contain a crystalline structure. It has a uniform structure, good permeability, and high chemical and biological reactivity. Good processability, easy biodegradation and digestion and absorption; its disadvantage is that the original granular structure of starch has been destroyed, making it difficult or even impossible to separate, purify and dry the product, and cannot produce high-purity products, which directly affects the manufacture of the starch product The development of technology, the increase of product varieties and the expansion of application fields. At present, only a few kinds of amorphous gelatinized starch products such as pregelatinized starch are produced.

文献中已经公布的非晶颗粒态淀粉的制备方法都是采用交联化学改性的方法，先对淀粉颗粒进行高交联化学改性，使得淀粉颗粒进行加热、加碱或其它非晶化转化时，颗粒的膨胀程度受到交联化学键的限制而只发生有限的膨胀，最终制备得到非晶颗粒态交联淀粉。这种淀粉颗粒虽然同时具有非晶性和颗粒性，但是，其最大的缺陷是由于颗粒内大量交联键的存在使其失去了淀粉最基本的糊化特性，导致其应用因无法糊化和制备成良好的淀粉糊受到极大的限制。在工业应用上无法进行糊化成均匀的淀粉糊。The preparation methods of amorphous granular starch that have been published in the literature all adopt the method of cross-linking chemical modification. Firstly, the starch granules are highly cross-linked and chemically modified, so that the starch granules are subjected to heating, alkali addition or other amorphous transformations. When , the expansion degree of the granules is limited by the cross-linking chemical bonds, and only limited expansion occurs, and finally the amorphous granular cross-linked starch is prepared. Although this kind of starch granules has both amorphous and granular properties, its biggest defect is that due to the existence of a large number of cross-links in the granules, it loses the most basic gelatinization characteristics of starch, resulting in the inability to gelatinize and Preparation of good starch pastes is extremely limited. Gelatinization cannot be performed into a uniform starch paste in industrial applications.
