玉米、馬鈴薯和甘薯淀粉是世界食品工業(yè)中重要和常用的原料,如在無麩質食品中的應用。然而,天然淀粉的結構與性質限制了其應用潛力。作為一種非熱物理改性技術,高靜水壓已成功用于延長新鮮和加工食品的貨架期,且對其感官品質、營養(yǎng)價值和香氣成分的影響很小,受到了研究人員和食品工業(yè)界的廣泛關注。然而,目前還沒有關于高靜水壓處理對玉米、馬鈴薯和甘薯淀粉特性影響的比較研究,以及高靜水壓處理淀粉在無麩質模型面團中的應用研究。本課題研究了高靜水壓對玉米、馬鈴薯和甘薯淀粉物化、熱特性和結構特性的影響。在此基礎上,研究了高靜水壓處理淀粉和添加不同糖對無麩質模型面團熱機械學、流變學和微觀結構的影響,以期揭示高靜水壓處理淀粉影響無麩質模型面團產氣持氣性能的可能機理。具體研究結果如下:（1）高靜水壓處理（100、300和500 MPa,25℃下處理15和30 min）對玉米、馬鈴薯和甘薯淀粉（20%,w/w）的物化、熱特性和結構特性有顯著影響。高靜水壓處理后,三種淀粉的直鏈淀粉和破損淀粉含量均有所增加,但溶解度和膨脹勢均降低。玉米淀粉的熱力學性質與馬鈴薯淀粉、甘薯淀粉有顯著差異。500 MPa處理的玉米淀粉完全糊化,粒...
