玉米淀粉在啤酒酿造中的使用

玉米淀粉对于酿造师来说是一种最纯的淀粉原料 ,它没有得到广泛使用的原因主要是其价格比玉米粉或酿造大米昂贵 ,不过近几年来玉米淀粉的价格已接近大米的价格 ,为酿造师提供了良好的选择余地。玉米淀粉的蛋白质、脂肪、多酚含量很低 ,使用玉米淀粉作为辅料能延长啤酒的保质期、提高啤酒的风味稳定性、降低啤酒的色度。玉米淀粉可全部转化为可溶性物质 ,所以不会引起过滤问题。玉米淀粉应用的市场前景在很大程度上取决于其相对价格

The Utilization of Refined Maize Starch in Brewing

Refined maize starch is by far the purest starch available to the brewer Its use has been limited because of its price is higher relative to those of corn grits and brewers' rice Within the last few years, however, the price of refined maize starch has come close to that of rice and offers the brewer an attractive alternative It contains very little nitrogenous material and lipid and polyphenol, so using of refined maize starch as a brewing adjunct could prolong beer shelf-life, improve beer flavour stability, and decrease beer color Since starch is wholly coverted to soluble materials, it don't cause run-off problems The outlook of refined maize starch as a brewing adjunct will depend to a large extent on relative pricing
