淀粉质量对啤酒生产和质量的影响 总被引:1,自引:0,他引:1
自05年开始,许多啤酒厂大量使用淀粉作为啤酒生产的辅料。有关讨论淀粉在啤酒中应用的话题已经充分展开,但淀粉质量应达到怎样的标准才能适合啤酒生产使用呢?在将淀粉作为啤酒生产的辅料之一时,需要研究淀粉的一些质量指标对啤酒是否有影响。通过我厂使用不同淀粉的实践,发现淀粉的外观质量和一些检测指标存在较大差异,如总酸、pH值、SO2含量等均有较明显的差别。本文通过对淀粉生产过程的了解以及对不同淀粉指标的跟踪,初步研究了淀粉质量指标对啤酒质量的影响。淀粉的外观质量直接反应淀粉加工过程的卫生状况,理化指标对啤酒生产过程和啤酒质量有较大影响。 相似文献

玉米淀粉已在加工过程中完全脱胚、去皮,无脂肪、无异味,适合于啤酒生产。实践证明,玉米淀粉代替大米作为啤酒的辅助原料完全是可行的。我们对不同比例的淀粉加量进行了试验,50%的玉米淀粉用于啤酒效果满意。 相似文献

以糯玉米淀粉为原料,以次氯酸钠为氧化剂,氢氧化钠为催化剂,对氧化糯玉米淀粉的制备及性能进行了研究.考察了反应时间、反应温度、次氯酸钠用量、pH对氧化糯玉米淀粉羧基含量的影响,采用酸碱滴定法测定氧化糯玉米淀粉羧基含量.试验结果表明,随着次氯酸钠用量增加,氧化糯玉米淀粉的羧基含量也随之增大;在一定时间范围内,氧化糯玉米淀粉的羧基含量随反应时间的增加而增加;反应温度和pH对氧化糯玉米羧基含量的影响呈倒抛物线趋势,存在最大值.糯玉米淀粉经氧化后,其液透明度和黏度热稳定性提高,但其冻融稳定性和凝沉性下降. 相似文献

Extruded corn starch (ECS) was used as an adjunct during beer fermentation and the fermentable sugars in the wort made with ECS and cooked corn starch (CCS) were determined using high‐performance liquid chromatography. The flavour compounds of beer made using ECS and CCS were determined using headspace solid‐phase micro‐extraction gas chromatography–mass spectrometry, and eight volatile compounds in ECS and CCS beer were quantified using gas chromatography (GC). Five fermentable sugars (fructose, glucose, sucrose, maltose, maltotriose) were detected in both samples, and their content in ECS wort was higher than in CCS wort, except for maltose. Seventy‐three flavour compounds were identified and quantified in ECS beer, while 58 compounds were determined in CCS beer. Both ECS and CCS can be used to produce beer; however, the concentration of characteristic beer flavour compounds in ECS beer was higher than in CCS beer.

Incompletely degraded corn starch particles often seriously inhibit wort filtration and decrease a brewery’s beer productivity. Herein, the inhibiting factors of starch hydrolysis and the application of amylases to degrade residual starch were evaluated. The results showed that resistant starch and the amylopectin of corn starch were not the inhibiting factors. Almost all residual starch left in the spent grain layer was proved to be degradable by amylases. Mesophilic α-amylase was selected through a comparison of nine amylases, which increased the wort filtration rate by 44%. However, >6% of corn starch was still left after mashing when a high ratio of corn starch to water (>1:3.5) was used in liquefaction. The low water content in liquefaction was proved to be the key inhibiting factor. Considering the existing equipment and brewing technology, the application of mesophilic α-amylases should be a simple and effective method for enhancing the hydrolysis of corn starch and accelerating the wort lautering process during a high-adjunct-ratio beer brewing process. 相似文献
