变褐

Bread aroma is enhanced, as is the crust color, by a build-up of melanoidin compounds from nonenzymatic browning reactions.

面包的风味改善了，面包表皮的颜色也由于非酶褐变反应所生成的类黑精化合物而有所改善。

Melanoidin coloring substance came into existence more or less after long-term food storage or food thermal treatment.Such phenomenon was named as Maillard reaction because enzymes were not involved in the reaction.

食品在加热处理或长期贮存后，都会产生不同程度的类黑精色素，如面包、烤肉、熏鱼、咖啡、茶及酱油等调味品中，都有类黑精色素的产生，因为这一类反应没有酶的参与，故又称非酶褐变(N o-enzym atic Brow ning)反应。
