The result showed that non - enzymatic browning of greengage juice could be inhibited and natural primrose yellow could be kept in the plasming of greengage by adding 0 . 2 % ( mass fraction ) sodium erythorbate ; non - enzymatic browning of greengage juice was restrained more remarkably by vacuum concentration than by normal pressure concentration ; the non - enzymatic browning of greengage juice increased and the color darkened with the increase of concentration and processing temperature ; non - enzymatic browning of greengage juice in the storage could be inhibited under the condition of low temperature , and frozen storage was the best store method of greengage concentrated juice 摘要結果表明:在青梅果打漿時加入質量分數為0 . 2 %的異抗壞血酸鈉,可防止果汁氧化褐變而保持天然淡黃色澤;減壓濃縮較常壓濃縮明顯抑制了非酶褐變的發生;隨著果汁含量和加工溫度的提高,非酶褐變加快,色澤加深;低溫有利于青梅濃縮汁的貯藏,冷凍貯藏是最佳的貯藏條件。
