酪朊胶粘贴啤酒商标耐水性的研究

本文对酷朊胶粘贴的啤酒商标的耐水性进行了较系统的研究。试验证明耐水性和酪朊胶组分、贴标时胶的用量、贴标质量、贴标后放置的时间以及标本身的质量等各因素有关。在具有较好耐水性的酪朊胶基础上保持一定的上胶量（７８．５ｃｍ＾２球啤普通标，２５０ｍｇ左右），胶上得均匀，标贴得平整，贴后放置十天左右，再在约５℃冰水中冷冻，商标就能在７２小时内不自行脱落。     

高效商标粘贴剂应用情况

于1993年底珠江啤酒集团公司与广州市食品工业研究所合作。研制成功高效商标粘贴剂。它是以干酪素为主要原料，经过上百次反复试验而成的一种高效粘贴剂，简称为酪朊胶。产品经珠江啤酒集团公司包装厂半年多的试用，其性能优异且全面。主要特点；初粘力强，流动性好，贴标后干燥速度快且易于调节（根据气温适当调整配方），耐冻水浸，热水易脱，用胶量少等。应用以来的实际情况介绍如下。在高速机（4万支州州4）上应用，贴普通标，贴标速度可达毛万支川。时，贴标率99．9％以上，正标率高达98G％，每公斤胶可贴标g000支左右。贴精装标（带…     

高效商标粘贴剂研究报告

一、前言高效商标粘贴剂的研制，是广州市科委下达的行业课题。主要目的是解决珠江啤酒公司九三年引进的高速装瓶机（4万支／小时）贴标代替进口粘贴胶。以及提高原用机的贴标率等问题。高效商标粘贴剂要求达到：初粘力强，流动性好，干燥快，耐冻水浸，热稀碱水冲洗易脱落，以及不长霉，腐蚀性小等。在研究分析珠江啤酒公司原用胶和其他啤酒厂用胶及进口酪肮脏的基础上，先后选择两个方案进行试制。一是以缩醛类树脂为主体，二是以酪素为基料（制备成的胶简称酪阮胶）。第一方案经一段时间试制试用未能达到指标。转入第二方案时，一开始就…     

常用的几种标签和标胶介绍

标签是啤酒产品的外观质量的重要因素,紧贴瓶壁、平整无皱是贴标质量的基本要求。而贴标质量的优劣,与标签纸结构以及胶水质量、性质、状态等因素密切相关。目前,常用的标签种类主要有铜版纸商标、湿强纸商标以及镀铝纸商标,而常用的胶水主要包括淀粉胶、化学胶、酪素胶及合成胶这四种。本文中,笔者介绍了上述几种常用的标签和标胶,并针对其特点进行分析,仅供读者参考。     

啤酒商标胶的应用情况及发展前景

1商标肢的应用现状啤酒瓶装设备用的商标粘合剂好坏直接影响到啤酒的包装和产量，影响到啤酒的感观。现代啤酒制造商要求，商标胶必须无毒，商标在冰水中浸泡24小时不脱落，回收旧瓶时旧标经弱碱水浸泡又易脱掉。就目前情况来看，我国的商标胶还跟不上发展的需要，有些生产厂家制作的商标粘合剂还存在初粘力低，速平性差，易发霉，在高速瓶装机上有甩胶、滚标错位等问题。提高商标胶的综合性能，满足每小时4万瓶瓶装机的贴标要求，粘贴SDel05克铜板标纸和进口包铝箔纸是当前商标胶的一般要求，我国的商标胶应赶上发展的需要。2商标胶的综合…     

玻璃瓶贴标影响因素与标机故障分析

由于各啤酒公司使用的标机型号不同,标机维护操作技能有一定差异,贴标异常的故障因素与调整,备品备件的准备也不同,商标和标胶质量波动对贴标质量的影响也较大。本文就贴标过程影响因素与标机常见故障进行分析,提出一些解决措施。     

啤酒贴标质量的控制要点

啤酒贴标质量是影响啤酒外观、消费者满意度的关键要素。本文介绍了提高贴标质量的设备调整、贴标机操作、原材物料精益化方面的相关内容,供大家参考。1设备调整1)标仓标钩长度的调节:调节不正确会使标纸因受力不均匀而造成商标取胶不均匀或标钩过紧处的标纸撕裂。标钩长度(标钩端部到标盒盒体边缘的距离)为30.5mm且平齐垂直。每个标钩必须位于标板槽中心,否则易引起商标变形而难以刷平或头标撕破等。标钩吃进量2～4mm且在同一平面上。标钩压紧力的调节:调节过紧易产生商标变形,不平整,商标胶不均匀,甚至产生气泡。调节

降低胶水消耗的改进

目前啤酒贴标主要采用酪素胶价格较高（13000元／吨），降低胶水消耗对节约成本有明显的贡献，同时还有助于提高贴标质量，减少皱标和滑标。各公司即使使用相同型号的贴标机，贴标胶水消耗控制水平仍有很大差异，较好的可以控制在0．6～0．7kg/kL，而较差的则可达1．0kg／kL以上。我公司包装部2004年1～5月贴标胶水消耗月平均1．05kg/kL，而且有部分班次胶耗大于1．3kg／kL（见图1和图2）．     

Reliable identification of grapevine rootstock varieties using RAPD PCR on woody samples

Since grapevine ( Vitis spp .) rootstock material is being traded increasingly as disbudded woody material a lack of distinctive morphological features on such material necessitates an alternative and reliable means of identification. Methods described here were developed for rapid and efficient extraction of DNA from woody samples rich in phenolic compounds and polysaccharides, and for subsequent identification of varieties by RAPD PCR. Using these methods, and with the application of only one selected RAPD primer, we were able to differentiate sixteen rootstock varieties, including the seven varieties most commonly used in Germany. Problems commonly encountered with reproducibility of RAPD patterns were avoided by choosing primers with a dinucleotide sequence and a high G/C content that allowed a rather high annealing temperature of 45°C. Methods described here should also be useful for other horticultural crops, especially those with woody tissues rich in phenolic compounds and polysaccharides.     

Aroma characterization of various apricot varieties using headspace–solid phase microextraction combined with gas chromatography–mass spectrometry and gas chromatography–olfactometry

The characterization of the aromatic profile of several apricot cultivars with molecular tracers in order to obtain objective data concerning the aromatic quality of this fruit was undertaken using headspace–solid phase microextraction (HS–SPME). Six apricot cultivars were selected according to their organoleptic characteristics: Iranien, Orangered, Goldrich, Hargrand, Rouge du Roussillon and A4025. The aromatic intensity of these varieties measured by HS–SPME–Olfactometry were defined and classified according to the presence and the intensity of grassy, fruity and apricot like notes. In the six varieties, 23 common volatile compounds were identified by HS–SPME–GC–MS. Finally, 10 compounds, ethyl acetate, hexyl acetate, limonene, β-cyclocitral, γ-decalactone, 6-methyl-5-hepten-2-one, linalool, β-ionone, menthone and (E)-hexen-2-al were recognized by HS–SPME–GC–O as responsible of the aromatic notes involved in apricot aroma and considered as molecular tracers of apricot aromatic quality which could be utilized to discriminate apricot varieties.     

Tests of potential functional barriers for laminated multilayer food packages. Part I: Low molecular weight permeants

The advent of the functional barrier concept in food packaging has brought with it a requirement for fast tests of permeation through potential barrier materials. In such tests it would be convenient for both foodstuffs and materials below the functional barrier (sub-barrier materials) to be represented by standard simulants. By means of inverse gas chromatography, liquid paraffin spiked with appropriate permeants was considered as a potential simulant of sub-barrier materials based on polypropylene (PP) or similar polyolefins. Experiments were performed to characterize the kinetics of the permeation of low molecular weight model permeants (octene, toluene and isopropanol) from liquid paraffin, through a surrogate potential functional barrier (25 μm-thick oriented PP) into the food simulants olive oil and 3% (w/v) acetic acid. These permeation results were interpreted in terms of three permeation kinetic models regarding the solubility of a particular model permeant in the post-barrier medium (i.e. the food simulant). The results obtained justify the development and evaluation of liquid sub-barrier simulants that would allow flexible yet rigorous testing of new laminated multilayer packaging materials.

The development of reference materials for paralytic shellfish poisoning toxins in lyophilized mussel. II: Certification study

This paper describes the second part of a project undertaken to develop certified mussel reference materials for paralytic shellfish poisoning toxins. In the first part two interlaboratory studies were undertaken to investigate the performance of the analytical methodology for several PSP toxins, in particular saxitoxin and decarbamoyl-saxitoxin in lyophilized mussels, and to set criteria for the acceptance of results to be applied during the certification exercise. Fifteen laboratories participated in this certification study and were asked to measure saxitoxin and decarbamoyl-saxitoxin in rehydrated lyophilized mussel material and in a saxitoxin-enriched mussel material. The participants were allowed to use a method of their choice but with an extraction procedure to be strictly followed. The study included extra experiments to verify the detection limits for both saxitoxin and decarbamoyl-saxitoxin. Most participants (13 of 15) were able to meet all the criteria set for the certification study. Results for saxitoxin.2HCl yielded a certified mass fraction of <0.07 mg/kg in the rehydrated lyophilized mussels. Results obtained for decarbamoyl-saxitoxin.2HCl yielded a certified mass fraction of 1.59+/-0.20 mg/kg. The results for saxitoxin.2HCl in enriched blank mussel yielded a certified mass fraction of 0.48 +/- 0.06 mg/kg. These certified reference materials for paralytic shellfish poisoning toxins in lyophilized mussel material are the first available for laboratories to test their method for accuracy and performance.
