支鏈澱粉在蔬菜和水果乾中的應用

普魯蘭 is highly effective for food preservation.對食品保鮮非常有效。 Coating fresh fruits such as apples, mangoes, and citrus can effectively prevent decay and reduce nutrient loss.塗上新鮮水果（如蘋果，芒果和柑橘）可以有效防止腐爛並減少營養損失。 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.以荔枝的保鮮為例，由於荔枝收割後容易變褐，變質，變質，因此傳統上通過二氧化硫熏蒸處理，亞硫酸鹽溶液處理，化學殺菌劑浸泡處理等物理化學方法進行保鮮。 These preservation methods are inexpensive, but the substances used are toxic and harmful to humans.這些保存方法便宜，但是所使用的物質是有毒的並且對人類有害。 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，如果荔枝用支鏈澱粉包衣溶液保存，並在夏天以16度的溫度保存5小時，則與未處理的荔枝相比，保存時間會延長XNUMX小時。 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度環境下可比未處理的水果保存XNUMX天以上，保鮮效果優於傳統藥物，具有明顯的優勢。

乳液組成 支鏈澱粉 and other hydrophobic substances is used as a fresh-keeping vegetable coating, and the preservation effect is remarkable.和其他疏水性物質用作蔬菜保鮮塗層，保鮮效果顯著。 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，蠶豆會在2-3天后變黑，在塗層後的20天內仍保持綠色，其保質期延長了3倍。 Green asparagus shrinks at 5 ° C for 10-0.5 days so it cannot be sold.綠蘆筍在5°C下會收縮XNUMX-XNUMX天，因此無法出售。 But the coating remains unchanged after XNUMX days, preserving the value of the commodity.但是塗層在XNUMX天后保持不變，從而保留了商品的價值。 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%.如果將生菠菜切成適當的大小，噴灑XNUMX％的支鏈澱粉溶液，冷凍乾燥，並用防潮袋密封XNUMX個月，顏色和風味的變化就很小，維生素僅減少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.將支鏈澱粉丙酸酯溶液（替代值為XNUMX）噴灑在切好的菠菜或其他蔬菜上，凍乾，在防潮袋中保存XNUMX個月，顏色和形狀略有變化，烹飪後風味保持新鮮。
對於冷凍乾燥的蔬菜，塗層還具有抗氧化，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，豆類，乾魚和貝類，整條炸薯條，蘿蔔和極薄的噴霧劑 支鏈澱粉 薄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.通過研究，研究人員還發現，支鏈澱粉本身不具有殺菌和抑菌作用，而多靈類，異丙洛酮和TBZ具有良好的殺菌，抗病毒感染，防腐和疾病預防作用。 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.這些殺蟲劑XNUMX-XNUMX（通常有效濃度）與XNUMX％支鏈澱粉混合用於水果處理，由於支鏈澱粉具有良好的成膜性，因此具有更明顯的防腐作用。 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.殺蟲劑應用於水果表面，而支鏈澱粉多醣可以阻斷氧氣，延遲殺真菌劑的分解，並延長藥物的作用。
The effect of pullulan treatment of fruits on the shelf life was more significant.支鏈澱粉處理水果對貨架期的影響更為顯著。 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.使用支鏈澱粉和殺蟲劑的混合物後，可以很好地保持水果的保質期，減少水分流失，並延長保質期。
