支链淀粉在蔬菜和水果干中的应用

普鲁兰 is highly effective for food preservation.对食品保鲜非常有效。 Coating fresh fruits such as apples, mangoes, and citrus can effectively prevent decay and reduce nutrient loss.涂上新鲜水果（如苹果，芒果和柑橘）可以有效防止腐烂并减少营养损失。 Taking the preservation of litchi as an example, since litchi is easily browned, rotted and deteriorated after being harvested, it is traditionally used for preservation through physical and chemical methods, such as sulfur dioxide fumigation treatment, sulfite solution treatment, chemical fungicide soaking treatment.以荔枝的保鲜为例，由于荔枝收割后容易变褐，变质，变质，因此传统上通过二氧化硫熏蒸处理，亚硫酸盐溶液处理，化学杀菌剂浸泡处理等物理化学方法进行保鲜。 These preservation methods are inexpensive, but the substances used are toxic and harmful to humans.这些保存方法便宜，但是所使用的物质是有毒的并且对人类有害。 However, if the lychee was preserved with pullulan coating solution, and stored for 84 hours in the summer at 35 degrees, it would extend 72 hours longer than the untreated.但是，如果荔枝用支链淀粉包衣溶液保存，并在夏天以16度的温度保存5小时，则与未处理的荔枝相比，保存时间会延长XNUMX小时。 It can be kept XNUMX days longer than the untreated fruit in the XNUMX degree environment, and it has better preservation effect than the traditional medicine method, with quite obvious advantage.在XNUMX度环境下可比未处理的水果保存XNUMX天以上，保鲜效果优于传统药物，具有明显的优势。

乳液组成 支链淀粉 and other hydrophobic substances is used as a fresh-keeping vegetable coating, and the preservation effect is remarkable.和其他疏水性物质用作蔬菜保鲜涂层，保鲜效果显着。 For example, at 25 ° C, the broad bean will blacken in 2-3 days, and is still keep green till14 days after coating with its shelf life extended by 5 times.例如，在25°C下，蚕豆会在2-3天后变黑，在涂层后的20天内仍保持绿色，其保质期延长了3倍。 Green asparagus shrinks at 5 ° C for 10-0.5 days so it cannot be sold.绿芦笋在5°C下会收缩XNUMX-XNUMX天，因此无法出售。 But the coating remains unchanged after XNUMX days, preserving the value of the commodity.但是涂层在XNUMX天后保持不变，从而保留了商品的价值。 If the raw spinach is cut into appropriate size, sprayed with XNUMX% pullulan solution, freeze-dried, and sealed with moisture-proof bag for XNUMX months, the color and flavor change is small, and the vitamin is only reduced by XNUMX%.如果将生菠菜切成适当的大小，喷洒XNUMX％的支链淀粉溶液，冷冻干燥，并用防潮袋密封XNUMX个月，颜色和风味的变化就很小，维生素仅减少XNUMX％。 Pullulan propionate solution (with a replacement value of XNUMX) was sprayed on the cut spinach or other vegetables, lyophilized, stored in a moisture-proof bag for XNUMX months, and the color and shape were slightly changed, and the flavor remained fresh after cooking.将支链淀粉丙酸酯溶液（替代值为XNUMX）喷洒在切好的菠菜或其他蔬菜上，冻干，在防潮袋中保存XNUMX个月，颜色和形状略有变化，烹饪后风味保持新鲜。
对于冷冻干燥的蔬菜，涂层还具有抗氧化，保色性和香味的作用。
含高含量油脂的水果，例如花生，核桃，杏仁，豆类，干鱼和贝类，整条炸薯条，萝卜和极薄的喷雾剂 支链淀粉 膜可以有效防止氧化。
Through study, researchers also found that pullulan itself does not have bactericidal and bacteriostatic effects, while polylings, iprodione and TBZ have good bactericidal, antiviral-infection, antiseptic and disease prevention effects.通过研究，研究人员还发现，支链淀粉本身不具有杀菌和抑菌作用，而polylings，异丙洛酮和TBZ具有良好的杀菌，抗病毒感染，防腐和疾病预防作用。 These insecticides 1000-6 (commonly effective concentration) mixes with 1% pullulan for fruit treatment, which has more obvious antiseptic effect because pullulan has good film forming properties.这些杀虫剂XNUMX-XNUMX（通常有效浓度）与XNUMX％支链淀粉混合用于水果处理，由于支链淀粉具有良好的成膜性，因此具有更明显的防腐效果。 The insecticide is applied to the surface of the fruit, while the pullulan polysaccharide can block oxygen, delay the decomposition of the fungicide, and prolong the effect of the drug.杀虫剂应用于水果表面，而支链淀粉多糖可以阻断氧气，延迟杀真菌剂的分解，并延长药物的作用。
The effect of pullulan treatment of fruits on the shelf life was more significant.支链淀粉处理水果对货架期的影响更为显着。 After using mixture of pullulan and insecticide, the quality of the fruit shelf life is well maintained, the water loss is reduced, and the shelf life is prolonged.使用支链淀粉和杀虫剂的混合物后，可以很好地保持水果的保质期，减少水分流失，并延长保质期。
