食品工业用变性淀粉

<正> 淀粉是由许多D—葡萄糖通过α—1.4糖苷键及α—1.6糖苷键连接而成的生物高分子物体,连接葡萄糖残基的糖苷键以及分子间的氢键在受到加热等物理因素的影响时,会发生断裂,而葡萄糖残基上具有的三个游离羟基可以和多种化学试剂反应。也就是说,淀粉在受物理、化学因素的影响时,均会发生质的变化,产生相应的淀粉衍生物,这些淀粉衍生物的性质与原淀粉的性质有着根本的不同,我们就称这些衍生物为变性淀粉。目前用于淀粉变性的方法主要有物理法、化学法以及酶修饰法。淀粉变性的目的就是为了改变淀粉的性质如糊化温度、热粘度、冷粘

Starch and Starch Derivatives Industry in India

Tapioca and maize are the major sources of starch in India. Tapioca starch is produced in very small units which are not extensively mechanized. This quality of the starch produced is not of a high quality. Maize starch is produced in mechanized units. The liberalization of the economy and growing consumerism bode well for the starch industry in India. Growth of the starch industry would depend on developing applications for starch as well as optimizing usage to derive maximum benefits. The unique properties of maize and tapioca should be considered.

Innovative Starch Derivatives as Textile Auxiliaries for Application in Sizing,Finishing and Flocculation

Innovative starch‐based polymeric products were synthesized for utilization as sizing agents, flocculants, and finishing agents. The synthesis involved reaction of starch and hydrolyzed starches with monochlorotriazinyl‐β‐cyclodextrin (MCT‐β‐CD) to yield starch grafted with cyclodextrin (St‐g‐CD). The latter was further reacted with 3‐chloro‐2‐hydroxypropyltrimethylammonium chloride (Quat‐188) to effect cationization of St‐g‐CD. Grafting of starch with cyclodextrin and cationization with Quat‐188 were concurrently expedited by reacting starch with both MCT‐β‐CD and Quat‐188 in a one‐step process using NaOH as catalyst. Maximization of the reaction of starch‐g‐CD with Quat‐188 (expressed as%N) and the concurrent reaction of starch with MCT‐β‐CD and Quat‐188 could be achieved at 40ºC for 90 and 120 min, respectively, by using NaOH as catalyst at concentrations of 8 and 15 mmol, respectively. These reaction conditions were employed to prepare six innovative polymeric starch derivatives. Derivatives I, II and III represent St‐g‐CD prepared from hydrolyzed starches having different molecular sizes after being cationized with Quat‐188. Derivatives IV, V and VI represent those prepared from reacting the hydrolyzed starch with both MCT‐β‐CD and Quat‐188 in a one‐step process. The six derivatives were characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Although all six derivatives bear cyclodextrin and Quat‐188 moieties, their characters and properties differ considerably, which was reflected on their efficiency as flocculants and sizing agents and as additive in durable press finishing (DP) of cotton fabric. The efficiency of the six derivatives when applied in these fields depends on the molecular size of the parent starch, the graft content of the in St‐g‐CD, the extent of cationization and the condition of application. At any event, however, the innovative derivatives in question exhibit salient features which advocate them for application in sizing, flocculation and DP finishing.     

Starch Derivatives for Flocculation of Ferric Soaps

Although water soluble synthetic polymers find wide applications as flocculating agents, the potential problem associated with their use is lack of biodegradability and high cost. Development of substitutes based on natural polymers can be more attractive from biodegradability point of view and the important factor here will be matching the performance. We have studied the flocculating effects of starch derivatives (cationic and anionic) for ferric soap flocculation at different pHs and compared their efficiency with synthetic flocculants like Zeetag-63 and Floc-acid-25. Charge interaction between colloidal particles and polymeric flocculating agents is one of the factors that contribute to the changes in rae and extent of flocculation. :Under certain pH conditions starch based flocculants are shown to perform better than the synthetic flocculants (Zeetag-63) and the effects are explained on the basis of variation of surface charge (measured by collid titration) of ferric soaps precipitated at different pHs.

New Starch Derivatives for the Coating Industry

Continuous enzyme conversion in a jet cooker offers a lot of benefits compared to batch conversion. The starch has improved binding properties and a better overall performance. Gelpermeation chromatography shows a more favourable molecular weight distribution for the continuous enzyme converted starch. Wheat starch is a valuable binder in paper coating compared to maize starch and potato starch, when the conversion happens in the right way; continuous jet cooking gives the best results. Modified starches, such as Mylbond AC, an esterified starch, are very suitable as cobinder in topcoat applications. They show excellent binding properties and react faster with insolubilizers than oxidized enzyme converted starch, as shown by DSC measurements.
