随着啤酒工业的发展,市场竞争愈加激烈。为了能在激烈的竞争中占领市场,除提高产品质量外,还要开发新产品。现在,南方不少啤酒厂已经研制生产出浓度11~18度的黑啤酒,在北方生产黑啤酒的厂家很少,我厂从1986年开始研制生产黑啤酒,现在生产的11度黑啤酒颇受用户欢迎,并已通过了省级鉴定。根据几年来的生产实际,我厂摸索出生产低浓度黑啤酒的一点规律,请同行们参考。 相似文献

为提高离子交换法生产硝酸钾过程中产生的氯化铵溶液进入氯化氨盐田的浓度,利用反渗透技术将收集平均浓度为15 g/L的低浓度氯化铵溶液依次经过保安过滤器、高压泵再进入一级反渗透本体装置浓缩,得到反渗透浓缩液和产水。浓缩液排入氯化铵盐田滩晒;产水再进入二级反渗透脱盐处理,得到脱盐水供生产使用。反渗透技术在离子交换法硝酸钾生产中的应用,既提高了氯化铵溶液进入盐田的整体浓度,也回收了脱盐水并用于生产使用,同时降低了生产成本,提高了生产效率。 相似文献

Beer is one of the oldest known alcoholic beverages produced by a yeast fermentation of a cereal extract that was germinated in water beforehand. The bitter taste of beer comes from the group of substances introduced during wort boiling, which are the extracted components of hops. The aim of this study was to determine some characteristics of beer (original extract, alcohol content, colour, pH, total acidity, carbon dioxide and bitterness values) during the three stages of the beer production process in a typical Romanian brewery. Measurements were carried out on 60 samples of beers, 10 measurements for each step of the process examining wort, unfiltered fermented beer and bottled beer (final product) from two different types of beer (light and dark). Statistical process control of the beer was performed. Losses in the bitterness units during the production process were between 24.7 and 41.54%, reported in terms of final product.

Based on the health‐promoting properties of xanthohumol (XN), the production of an enriched beer in this substance would be of interest to the brewing industry, from the perspective of pointing out the benefits that beer could bring consumer health. For that purpose, in this work efforts were applied to produce a beer enriched in XN. Also investigated was the influence of a XN‐enriched hop product on the content of XN and isoxanthohumol (IXN) in pale and dark beers. It was verified that XN was largely converted into IXN during wort boiling. However, the use of dark malts revealed a positive effect on the thermal isomerisation of XN. These results are indicative of the isomerisation‐inhibiting effect of the stout production process, which resulted in high levels of XN in the beer. Further losses of XN were due to incomplete extraction from the hops into the wort, adsorption to insoluble malt proteins and adsorption to yeast cells during fermentation. It was possible to produce a dark beer enriched in XN (3.5 mg/L) by using coloured malt (caramel malt, roasted malt and roasted malt extract) and a special XN hop extract combined with late hop usage during wort boiling. 相似文献
