專利名稱::淀粉水解的方法
技術(shù)領(lǐng)域:
:本發(fā)明涉及在低于顆粒狀淀粉的初始凝膠化溫度的溫度,將所述顆粒狀淀粉水解為可溶的淀粉水解產(chǎn)物的方法。
背景技術(shù):
:已經(jīng)描述了大量的方法用于將淀粉轉(zhuǎn)化為淀粉水解產(chǎn)物,諸如麥芽糖、葡萄糖或特制糖漿,用作甜味劑(sweetener)或用作其他糖類(lèi)如果糖的前體。葡萄糖也可以被發(fā)酵變?yōu)橐掖蓟蚱渌l(fā)酵產(chǎn)物,諸如檸檬酸、谷氨酸一鈉、葡糖酸、葡糖酸鈉、葡糖酸鈣、葡糖酸鉀、葡糖酸delta內(nèi)酯、異抗壞血酸鈉(sodiumerythorbate)、衣康酸、乳酸、葡糖酸;酮類(lèi);氨基酸,谷氨酸(單谷氨酸鈉(sodiummonoglutaminate))、青霉素、四環(huán)素;酶;維生素,如核黃素、B12、beta-胡蘿卜素或激素。淀粉是高分子量聚合物,其由葡萄糖單元的鏈組成。它通常由大約80%支鏈淀粉和20%直鏈淀粉組成。支鏈淀粉是分枝的多糖,其中alpha-1,4D-葡萄糖殘基的線狀鏈通過(guò)alpha-1,6糖苷鍵連接。直鏈淀粉是線狀的多糖,其由通過(guò)alpha-1,4糖苷鍵連接在一起的D-吡喃型葡萄糖構(gòu)建而成。在將淀粉轉(zhuǎn)化為可溶的淀粉水解產(chǎn)物的情況下,所述的淀粉被解聚(depolymerization)。常規(guī)的解聚方法由凝膠化步驟和兩個(gè)連續(xù)的處理步驟,即液化(liquefaction)處理和糖化(saccharification)處理組成。顆粒狀淀粉由微觀的顆粒組成,其在室溫不溶于水。當(dāng)將水性的淀粉漿體加熱時(shí),所述的顆粒膨脹并最終脹破,將所述的淀粉分子分散到所述溶液中。在此“凝膠化”(gelatinization)處理過(guò)程中,粘度有顯著的提高。由于在通常的工業(yè)過(guò)程中,所述的固體水平為30-40%,就必須將所述的淀粉變稀薄和“液化”,以使其能被處理。此粘度的降低現(xiàn)今主要通過(guò)酶法降解獲得。在液化步驟中,所述的長(zhǎng)鏈淀粉被alpha-淀粉酶降解為較小的分枝的和線狀的單元(麥芽糖糊精)。所述的液化步驟通常在大約105-110℃進(jìn)行大約5至10分鐘,然后在大約95℃進(jìn)行大約1-2小時(shí)。然后將所述的溫度降低到60℃,加入葡糖淀粉酶或beta-淀粉酶和任選的脫支酶,諸如異淀粉酶或支鏈淀粉酶,而且所述糖化處理進(jìn)行大約24至72小時(shí)。由前面的討論顯然,由于依據(jù)不同的步驟中溫度的不同要求,常規(guī)的淀粉轉(zhuǎn)化方法是非常消耗能量的。因此就需要能夠選出用于此方法的酶,可以進(jìn)行全過(guò)程而無(wú)需將所述淀粉凝膠化。這樣的方法是專利US4591560、US4727026和US4009074和EP0171218的主題。本發(fā)明涉及一步方法,用于在低于所述顆粒狀淀粉的初始凝膠化溫度的溫度,將顆粒狀淀粉轉(zhuǎn)化為可溶的淀粉水解產(chǎn)物。
