研究了金属拉西环填料、金属鲍尔环填料、金属矩鞍环填料、金属网波形填料和θ环填料5种金属填料对二氧化碳萃取法生产低醇葡萄酒的影响。通过探讨金属填料的乙醇脱酒精能力和对葡萄酒中香气成分的影响,确定使用CO2萃取法进行低醇葡萄酒的生产是可行的,在金属拉西环填料、金属鲍尔环填料、金属矩鞍环填料、金属网波形填料和θ环5种填料中,θ环填料对低醇葡萄酒的脱乙醇能力最高,适于低醇葡萄酒的生产。在金属填料高度300 mm、萃取温度20 ℃、压力4.0 MPa和进料的气液体积流量比20:1的条件下,采用θ环填料进行低醇葡萄酒生产时,低醇葡萄酒中高级醇和二氧化碳变化较大,高级醇质量浓度从355.83 mg/L降至200.97 mg/L,降低了43.52%;二氧化碳上升至0.06 MPa,而对其他香气成分基本无影响。葡萄酒的乙醇体积分数从11.00%降至3.77%,乙醇体积分数降低了65.73%。 相似文献

近来,政府及有关行业对低醇饮料(如无醇啤酒、低醇葡萄酒等)的生产工艺很感兴趣。如同其它许多国家一样,法国对这方面的问题更为敏感,因为法律上严禁在葡萄酒中加水。目前有关无醇啤酒、低醇葡萄酒的生产工艺已有很多专利。现在,可以应用一种特殊的薄膜,通过反渗析法生产低醇葡萄酒及其它饮料。有的 相似文献

低醇(无醇)葡萄酒的生产 总被引:7,自引:0,他引:7

自20世纪70年代,低醇(无醇)葡萄酒逐渐进入消费市场,尽管在整个葡萄酒市场中,这类产品仅占大约2%~5%的份额,但一些特殊人群:如司机、孕妇、某些对酒精不适的人群,饮用低醇(无醇)葡萄酒,既能享受到葡萄酒的美味和营养,又可避免其中的酒精带来的不良作用, 并且低醇(无醇)葡萄酒所含热量仅是普通葡萄酒的1/2,因此该产品作为一种休闲食品逐渐流行。目前美国、英国、澳大利亚、新西兰等国家市场上都有销售。其中美国的年产量约50万箱,销售收入达2亿多美元。关于低醇(无醇)葡萄酒的标准,各国不尽相同,一般规定无醇葡萄酒的酒… 相似文献

果酒的研究与开发现状 总被引:5,自引:0,他引:5
果酒是以新鲜水果或果汁为原料,经发酵酿制成的发酵酒,酒精度普遍在12%vol左右。果酒具有酒度低、营养丰富、果香浓郁、柔和协调等特点,深受消费者喜爱。近年来,果酒种类不断丰富,市场消费也有所提高,但仍存在果酒技术基础薄弱、标准及关键技术缺乏等问题,造成果酒产业发展较为缓慢的现象。该文主要从果酒营养价值、水果原料及果酒产量、政策指引、果酒开发现状、技术进展及果酒市场等方面进行论述,并对我国果酒行业的研究方向及技术改进进行展望,为今后果酒技术的研究、行业政策制定及产品市场定位等提供一定的理论依据。 相似文献

Background and Aims: Deep red full‐bodied wines can only be obtained from grapes with complete phenolic maturity, which frequently produce wines with high pH and alcohol content. The present study focuses on a new procedure for simultaneously reducing pH and ethanol content. Methods and Results: Grapes from cluster thinning were used to produce a very acidic low‐alcohol wine. The wine was treated with high doses of charcoal and bentonite. This odourless and colourless wine was used to reduce pH and ethanol content of wine produced from grapes, which had reached complete phenolic maturity. The anthocyanin and proanthocyanidin concentrations, the mean degree of polymerisation and the monomeric composition of proanthocyanidin of reduced‐alcohol wines were similar to those of their corresponding controls. Since the pH was lower, the colour of the reduced‐alcohol wines was more intense. No significant differences were found between reduced‐alcohol wines and their controls by triangle sensory tests using dark glasses for two of the three studied cultivars. Conclusion: The procedure described allowed production of wines with reduced alcohol content and pH, while retaining similar phenolic content and sensory properties. Significance of the Study: The proposed procedure is easy to apply, does not require specific equipment and offers a means of addressing the problem of wines developing high ethanol and low pH as a result of over‐ripening of grapes. 相似文献

Production technologies for reduced alcoholic wines 总被引:1,自引:0,他引:1
The production and sale of alcohol-reduced wines, and the lowering of ethanol concentration in wines with alcohol levels greater than acceptable for a specific wine style, poses a number of technical and marketing challenges. Several engineering solutions and wine production strategies that focus upon pre- or postfermentation technologies have been described and patented for production of wines with lower ethanol concentrations than would naturally arise through normal fermentation and wine production techniques. However, consumer perception and acceptance of the sensory quality of wines manufactured by techniques that utilize thermal distillation for alcohol removal is generally unfavorable. This negative perception from consumers has focused attention on nonthermal production processes and the development or selection of specific yeast strains with downregulated or modified gene expression for alcohol production. The information presented in this review will allow winemakers to assess the relative technical merits of each of the technologies described and make decisions regarding implementation of novel winemaking techniques for reducing ethanol concentration in wine. 相似文献

为了对黄酒中高级醇的高含量及在黄酒发酵过程中产生的高含量高级醇的因素及控制技术研究,对黄酒与其它酿造酒中高级醇含量进行了比较,认为高级醇既是黄酒的呈香、呈味物质,也是饮用黄酒后的上头物质。阐述了高级醇在黄酒生产中合成途径有埃尔利希形成机制和特定的氨基酸形成特定的高级醇,并介绍了黄酒生产中如何控制高级醇生成量的措施。 相似文献
