铁离子对啤酒质量影响的研究

THE STUDY OF ROLE OF IRON IONS IN BEER DETERIORATION

就铁离子对啤酒质量的影响进行了研究 ,结果表明铁离子能够促进啤酒沉淀物的形成 ,加速啤酒老化现象的产生 ,铁离子与自由基的产生有直接的关系。因此 ,在啤酒中应降低铁离子的含量 ,以降低其对啤酒质量造成的影响。

The paper studied the role of iron ions in beer deterioration,It is showed that iron ions can increase the amount of precipitate and accelerate the beer flavor staling.Iron ions have a relationship to the production of free radical.So it is very important to decrease the amount of iron ions in the beer.
