Description
技术领域
本发明涉及带包装的冷冻甜食,比如冰淇淋。尤其,本发明涉及包括柔性袋的带包装的冷冻甜食。
背景技术
近年来,已开发出用于分配冷冻甜食比如冰淇淋的系统,在所述系统中,预先包装好的冰淇淋被提供在容器中,可用手挤压容器以挤出甜食。尤其,已开发出基于袋的系统。
US2009/0208630A公开了带有吸嘴袋的冰淇淋和冷冻酸奶的制造方法和能够通过吸嘴袋狭窄的饮用管注入膨胀过程后的冰淇淋的装置。
现在本发明人认识到,存在对于改进用于分配像软冰这类的冷冻甜食的、基于袋的包装的需求。尤其,本发明人发现,存在对于这样的带包装冷冻甜食的需求:所述带包装冷冻甜食允许消费者以最小力气有效地从袋中挤出冷冻甜食。本发明人还认识到对于这样的袋的需求:所述袋允许冷冻甜食从所述袋更加彻底地清空,和/或所述袋允许冷冻甜食流以更加直接的方式朝着制品出口引导。
本发明人发现,通过将冷冻甜食包装在具有特定配置的袋中,可满足上述需求中的一项或多项。
发明内容
在第一方面中,本发明涉及一种带包装的冷冻甜食,所述带包装的冷冻甜食包括柔性袋,其中,袋包括壁,壁界定包含冷冻甜食的腔,并且壁沿着纵向方向从袋的基端延伸到袋的顶端,其中,顶端包括制品出口,冷冻甜食可通过所述制品出口从腔中被挤出,并且其中:
所述基端包括沿着横向方向延伸的角撑;
所述顶端包括沿着横向方向延伸的顶边缘;以及;
所述制品出口设置在所述顶边缘的角部处或邻近;
其中,所述壁至少在袋的基端处是可变形的,以朝着出口推动腔中的冷冻甜食并从所述出口挤出至少一部分的冷冻甜食。
通过提供这样的带包装的冷冻甜食,本发明人发现,消费者倾向于在带有角撑的基端(通常是袋的最厚部分)处抓住袋并挤压袋,这意味着分配力始终指向制品出口位于的顶端。此外,与例如US 2009/0208630 A中公开的袋不同,制品出口被设置在顶边缘的角部处或邻近。本发明人发现,当制品出口位于顶边缘中心(如在US 2009/0208630 A中的)时,消费者倾向于在侧边缘处抓住袋并挤压袋,这使分配力既指向顶端又指向基端,并且这可导致流和残留的冷冻甜食被阻塞在基端中。
优选地,袋包括侧边缘,每个侧边缘位于角撑的相反末端处,并且每个侧边缘沿着纵向方向延伸,这是因为:这进一步允许带有角撑的基端成为袋最厚的部分。为进一步阻止经由侧边缘保持和挤压袋,优选的是,所述侧边缘中的至少一个包括凹进部分,更优选地,所述侧边缘中的每个都包括凹进部分。
本发明人发现,当袋的尺寸不是太大时,以单手挤压基端即可达到从袋分配冷冻甜食所需的力。优选地,腔具有不超过500ml、更加优选地不超过475ml、最优选地不超过450ml的体积。另外或替代地,优选地,腔填充有不超过325g、更加优选地不超过275g、且最优选地不超过250g的冷冻甜食。
袋的腔应足以容纳至少一份冷冻甜食。然而,优选地,袋包含多份冷冻甜食。因此,优选的是,腔具有至少250ml、更加优选地至少275ml、且最优选地至少300ml的体积。另外或替代地,腔填充有至少100g、更加优选地至少150g、且最优选地至少175g的冷冻甜食。
制品出口可呈任何形式,比如简易的孔口。然而,优选地,出口呈吸嘴的形式,这是因为:这允许更加受控地分配例如到冰淇淋锥筒或其它容器中。为减少挤出甜食所需施加的手动力的量,优选的是,吸嘴具有至少10mm、更加优选地至少12mm、且最优选地从15至35mm的内径。
袋的壁大体上由塑料膜材料形成,更加优选地由多层层压的聚合物膜材料形成。优选的塑料是聚合物,比如聚乙烯、聚对苯二甲酸乙二醇酯、聚丙烯、聚酰胺及它们的组合。在一些实施例中,所述膜可以是箔-塑料层压材料,然而本发明人发现,如果所述膜未包含箔层,则可减少由袋传递到使用者手上的冰凉感觉。因此,优选的是,所述塑料膜材料不包括金属层。
大体上,袋由一卷连续的膜材料制成并由所述膜材料被切割和密封例如利用热封。优选地,顶边缘由塑料膜材料的相对面之间的密封部形成。另外或替代地,侧边缘由塑料膜材料的相对面之间的密封部形成。
在优选的实施例中,特别是在膜材料包括箔的情况下,带包装的冷冻甜食包括可移除的包套,所述可移除的包套至少部分地包围袋的壁,并且所述可移除的包套足够柔韧,从而允许通过包套传递手动力,以使壁至少在袋的基端处变形且由此朝着出口推动腔中的冷冻甜食并从出口挤出冷冻甜食。
本发明人发现,手持包含冷冻甜食的袋时感受到的冰凉感觉不仅取决于袋中所包含的制品的温度,而且还取决于凝结在壁外表面上的水分和/或冰的存在。因此,本发明的包套可以从袋移除,从而包套本身不需要储存在储存冷冻机中,否则包套的表面将易于发生凝结和结冰。因此,在从冷冻机中取出袋后将包套施加于袋时,消费者手持的表面是包套表面,触摸所述包套表面不会有不舒服的冰凉感觉。如本文中所使用的,术语“可移除”是指可以重复地移除包套并将之重新施加于袋。
包套可被移除的特征还有助于回收和/或重复利用,尤其是在包套由与袋壁不同的材料制成并因此不能以相同的方式再循环的情况下和/或包套比袋更加耐用且因此适于重复用于另外的袋的情况下。
尽管借由采用可移除的包套使在使用者手中引起的大部分不舒服的冰凉感觉减弱,然而可通过在包套中采用绝缘材料获得另外的优点。特别是,来自使用者手的热可迅速地传递通过袋的壁、促使袋内的冷冻甜食融化并因此破坏精心创建的微结构。因此,优选地,包套包括、基本上包括或者包含隔热材料。如本文中所使用的,“隔热”是指具有小于1Wm-1K-1、更加优选地小于0.5Wm-1K-1、且最优选地从0.0001至0.1Wm-1K-1的导热率。
另外或替代地,包套包括、基本上包括或者包含弹性体,最优选地,包套包括、基本上包括或者包含氯丁橡胶。弹性体材料提供额外的抓紧且因此增加手持和挤压袋的容易性。优选地,弹性体是发泡的,以增强隔热,最优选地,包套包括发泡氯丁橡胶。
包套使得:允许通过包套传递手动力,以使壁至少在袋的基端处变形。向袋的基部施加力是重要的,因为这不仅允许更加完全地清空袋,而且还允许力的有效传递。例如,本发明人发现,许多使用者发现抓住袋的基部且然后在挤压的同时从基部向上卷滚包套和壁是特别便利的。因此,优选的是,包套允许:通过包套传递手动力,以允许壁朝着出口卷起。另外或替代地,包套完全包封袋的基端。
包套越柔软,就越容易通过包套向袋壁传递力。因此,优选的是,包套是柔性的,使得包套无法自行站立。
优选地,包套使得:包套允许使用者抓住袋上的大体任何地方。因此,优选地,包套包围壁的外表面积的至少80%、更加优选地从90至100%。
优选地,包套具有保持部,保持部可释放地接合袋的顶端,以在冷冻甜食通过制品出口挤出期间将袋保持在包套内。术语“可释放”是指保持部可以与袋的顶端重复地接合和脱开接合。
重复使用可移除的包套的一个缺点在于,因早前的使用而沉积在包套上的冷冻甜食残留物会是脏污的或甚至造成卫生风险。通过设计这样的包套可以改善这些问题,使得所述包套在分配期间和在施加及移除包套期间与制品出口具有最低限度的接触。该目的可通过提供这样的包套被实现:包套包括朝着袋的顶端设置的开口,并且在保持部接合到袋的顶端之前,袋的基端可通过所述开口插入。更加优选地,保持部配置成使得保持部可在不经过制品出口的情况下接合到顶端。例如,保持部可包括一个或多个翼片,所述翼片在顶端的第一侧上从包套延伸并绕过出口通向第二侧,翼片可以反向固定到第二侧。
本发明的带包装的冷冻甜食允许高效地传递手动力,且因此允许高效地分配一系列冷冻甜食。然而,为协助分配,优选的是,袋内的冷冻甜食配制成软的而且在家用冷冻机中常见的温度范围下是稳定的。尤其,优选的是,冷冻甜食包含凝固点降低剂,凝固点降低剂的量为冷冻甜食重量的从25至35%,其中,凝固点降低剂的数均分子量<M>n小于250gmol-1。
出于本发明的目的,凝固点降低剂混合物的平均分子量由数均分子量<M>n限定(等式1)。其中wi是品类i的质量,Mi是品类i的摩尔质量,并且Ni是具有摩尔质量Mi的品类i的摩尔数。
限定在本发明中的凝固点降低剂包含:
·单糖和二糖
·含有以糖苷键结合的三至十个单糖单元的寡糖。
·葡萄糖当量(DE)大于20、优选>40且更加优选地>60的玉米糖浆。玉米糖浆为复杂多组分糖混合物,并且葡萄糖当量是常见的工业分类方法。由于玉米糖浆是复杂混合物,因此玉米糖浆的数均分子量<M>n可根据以下的等式2计算。(Journal of FoodEngineering,33(1997)221-226)
·赤藓糖醇、阿拉伯糖醇、甘油、木糖醇、山梨糖醇、甘露醇、乳糖醇和麦芽糖醇。
·乙醇。
制品中的冰量很大程度上由凝固点降低剂的数量和分子量决定。如果冰的量太高,则在某些储存冷冻机中常见的低温(例如-22℃)条件下,挤出甜食变得过于困难。因此,凝固点降低剂优选具有不超过250g mol-1的数均分子量<M>n,并且凝固点降低剂存在的量为冷冻甜食重量的至少25%。更加优选地,凝固点降低剂的量为冷冻甜食重量的至少26%、甚至更加优选地至少27%。
优选地,凝固点降低剂的数均分子量<M>n不大于240、更加优选地不大于230且最优选地不大于220g mol-1。
另一方面,如果凝固点降低剂的量变得过高和/或凝固点降低剂的分子量变得过低,则在某些储存冷冻机中常见的较高温度(例如-16℃)下,流变学将非常类似液体。因此,凝固点降低剂优选具有不小于200gmol-1的数均分子量<M>n,并且凝固点降低剂存在的量不超过冷冻甜食重量的35%。更加优选地,凝固点降低剂的量不超过冷冻甜食重量的34%,更加优选地不超过冷冻甜食重量的33%,并且最优选地不超过冷冻甜食重量的32%。
优选地,凝固点降低剂的数均分子量<M>n不小于205、更加优选地不小于208且最优选地不小于210g mol-1。
赤藓糖醇在赋予冷冻甜食以期望的流变学特性方面是特别有效的。此外,与一些其它的糖醇相比,赤藓糖醇不会产生令人不愉快的异味、不会过度地甜并且不会干扰食物的自然消化和排泄。因此,优选的是,凝固点降低剂包含赤藓糖醇。
优选地,赤藓糖醇的量为冷冻甜食重量的至少0.25%、更加优选地至少0.5%、甚至更加优选地至少0.7%且最优选地至少1%。
优选地,赤藓糖醇的量不是太高,否则甜食可能过于类似液体和/或可能难以配制具有期望甜度的甜食。因此,优选的是,赤藓糖醇的量不超过冷冻甜食重量的7%,更优选地不超过冷冻甜食重量的6%,甚至更优选地不超过冷冻甜食重量的5%,仍更加优选地不超过冷冻甜食重量的4%,并且最优选地不超过冷冻甜食重量的3%。
除赤藓糖醇外,优选的是,凝固点降低剂大体由糖类组成。优选地,凝固点抑制剂包含为凝固点降低剂重量的至少90%、更加优选地至少92%的单糖、二糖和低聚糖。凝固点降低剂中单糖、二糖和低聚糖和赤藓糖醇的总量优选为凝固点降低剂重量的至少98%、更加优选地99至100%。
特别优选的二糖是乳糖,因为乳糖提供了凝固点降低而未赋予高量的甜度。优选地,凝固点降低剂包含乳糖,所述乳糖的量为凝固点降低剂重量的至少5%,更加优选地为凝固点降低剂重量的从10至25%。乳糖可作为乳固体的一部分存在于甜食中和/或与乳固体分开添加。
某些凝固点降低剂是不期望的,因为它们会产生讨厌的味道和/或生理作用。
优选地,冷冻甜食包含按冷冻甜食重量计小于0.5%、更加优选地小于0.1%、且仍更加优选地小于0.01%、并且最优选地0%的乙醇。
优选地,冷冻甜食包含按冷冻甜食重量计小于1.5%、更优选地小于1%、且仍更加优选地小于0.5%、并且最优选地从0.2至0%的甘油。另外或替代地,冷冻甜食中阿拉伯糖醇、甘油、木糖醇、山梨糖醇、甘露醇、乳糖醇和麦芽糖醇的总量小于冷冻甜食重量的1.5%,更加优选地小于冷冻甜食重量的1%,且仍更加优选地小于冷冻甜食重量的0.5%,并且最优选地为冷冻甜食重量的从0.2至0%。
优选地,冷冻甜食包含按冷冻甜食重量计小于5%、更加优选地小于3%、并且最优选地从0至2%的果糖。
优选地,凝固点降低剂赋予冷冻甜食以期望的甜度而无需使用强力甜味剂。“强力甜味剂”是指以下中的一种或多种:阿斯巴甜、糖精、乙酰磺胺酸钾、阿力甜、奇异果甜蛋白、甜蜜素、甘草甜素、甜菊苷、新橙皮苷、三氯蔗糖、莫内林和纽甜。优选地,冷冻甜食大体不含强力甜味剂。更加优选地,冷冻甜食所包含的甜味剂的量小于赋予与1%蔗糖等同甜度所需的量,更加优选地小于赋予与0.5%蔗糖等同甜度所需的量,并且最优选地小于赋予与0.1%蔗糖等同甜度所需的量。另外或替代地,冷冻甜食包含小于0.003%的强力甜味剂,更加优选地小于0.001%,并且最优选地从0.0001至0%。
冷冻甜食大体通过冷冻诸如水、脂肪、凝固点降低剂、蛋白质(通常为乳蛋白)之类的成分和可选地诸如乳化剂、稳定剂、色素和调味剂之类的其它成分的混合物(更加优选地,巴氏杀菌混合物)制备。冷冻甜食包括冰淇淋、意式冰淇淋、冷冻酸奶、果汁冰糕、格兰尼它冰糕、刨冰等。优选地,冷冻甜食是冰淇淋。
冷冻甜食优选是充气的。“充气”是指甜食具有至少30%的膨胀率。更加优选地,冷冻充气甜食具有从70至135%、最优选地从80至110%的膨胀率。
膨胀率(OR)由下列等式3限定
在大气压下测量。环境温度为20℃。
冷冻甜食优选包含脂肪,脂肪的量为冷冻甜食重量的从1至15%、更加优选地从4至12%、且最优选地从5至10%。
冷冻甜食优选包含蛋白质,蛋白质的量为冷冻甜食重量的从0.5至8%、更加优选地从1至6%、且最优选地从1.5至5%。
在另一方面中,本发明提供了一种用于从包装分配冷冻甜食的方法,方法包括以下步骤:
(a)提供如第一方面中任何实施例所述的带包装的冷冻甜食;以及
(b)对带包装的冷冻甜食施加手动力,以使壁至少在袋的基端处变形且由此朝着出口推动腔中的冷冻甜食并从所述出口挤出至少一部分的冷冻甜食。
通常,在分配场景之间,袋被存储在家用冷冻机中。因此,优选的是,在分配各部分的冷冻甜食之间,袋被储存在温度低于-10℃、更加优选地温度为从-14至-25℃、并且最优选地温度从-16至-22℃的冷冻机中。
除了在示例中以外,本说明书中表示材料量、时间期间、长度范围、反应条件、材料物理性质和/或用途的所有数字都可以可选地理解为修饰有词语“大约”。
应注意到,在指定任何值的范围时,任何特定的上限值可以与任何特定的下限值相关联。
为避免疑义,“包含”一词旨在表示“包括”但不一定是“由……组成”或“由……构成”。换言之,所列举的步骤或选项不一定是详尽无遗的。
如本文中所发现的本发明的公开将被认为是涵盖存在于彼此多重从属的各权利要求中的所有实施例,而不考虑权利要求可能不存在多重从属或冗余重复的事实。
在特征与本发明的特定方面相关被公开的情况下,这样的公开也将视为在加以必要变更的条件下可适用于本发明的任何其它方面。

具体实施方式
图1a至图1c示出根据本发明的一个实施例的带包装的冷冻甜食(1)。带包装的甜食(1)包括包封冷冻甜食的柔性袋(2)。
袋包括由多层聚合物层压膜片形成的壁(4),其中,在形成角撑(7)之后,相反的前面和后面(11a、11b)在壁(4)的侧边缘(9a、9b)处和顶边缘(3)处热封在一起。袋从基端(6)沿纵向方向延伸到顶端(5)。角撑(7)位于基端(6)下面,角撑(7)形成基底,袋(2)基于所述基底自行站立在平坦表面上。如图1b中最佳所示,由于角撑板(7)的存在,袋(2)在基端(6)处是最厚的,并且袋沿着纵向方向具有渐缩的厚度。
在顶端(5)的一个角部处,呈吸嘴形式的制品出口(8)与壁(4)例如通过热封或粘合剂密封接合。尽管未被示出,但制品出口(8)优选通过可移除的盖可封闭。
图2示出了袋(2),正使用袋(2)以将一部分的冷冻甜食(40)分配到诸如威化锥筒之类的容器(50)中。袋的特定形状设计成促使使用者以第一只手(60a)抓住并挤压基端(6)、同时以第二只手(60b)支撑袋(2)的顶端(5),而管嘴(8)指向容器(50)。这确保分配力始终朝着吸嘴(8)而非朝着袋(2)的其它部分推动袋中的冷冻甜食。
图3示出了本发明的带包装的冷冻甜食(20)的另一实施例。袋(22)类似于图1和图2中所示的袋(2),并且具有吸嘴(28)和壁(24),壁沿着纵向方向从带有角撑的基端(26)延伸到顶端(25)并在顶边缘(23)和侧边缘(29a、29b)处密封。图3中所示的袋(22)与图1和图2中的袋的不同之处在于,每个侧边缘(29a、29b)包括凹进部分(30a、30b),所述凹进部分位于顶端(25)与底端(26)的大约中间。凹进部分(30a、30b)的存在使得由侧边缘(29a、29b)抓住袋(22)用于分配对于使用者由变得不合适,且因此进一步促使使用者在分配期间通过基端(26)和顶端(25)手持袋(20)。
图4示出了适于与图1的带包装的冷冻甜食(1)一起使用的包套(10),所述包套处于准备接收袋(2)的状态。包套由单片隔热弹性体材料(比如,例如发泡氯丁橡胶)制成,所述隔热弹性体材料卷成从基部开口(18)延伸至顶部开口(13)的筒形管状物,所述筒形管状物当被施加至袋(2)时,所述顶部开口设置在袋(2)的顶端(5)处。保持带(16)横跨基部开口(18)。包套(10)包括两个保持翼片(12a和12b),所述两个保持翼片分别设置在包套的顶边缘处和侧边缘处。每个翼片(12a、12b)具有可逆的附连区域(14a、14b),所述附连区域与包套(10)外表面上关联的附连区域(15a、15b)对应。附连区域对应成使得附连区域在接触时形成可逆结合。例如,翼片上的附连区域(14a和14b)可包括钩,并且对应区域(15a和15b)包括环,从而所述附连区域在接触时形成钩环结合。这种钩环紧固件是本领域中公知的,并且这种钩环紧固件包括以品牌销售的那些。
通过将袋(2)的基端(6)插入到包套(10)的顶部开口(13)中、且然后向上滑动包套直到带(16)接触袋(2)的基部为止,包套(10)被施加到袋(2)。然后,使翼片(12a和12b)绕袋(2)的顶端(5)折叠,并通过使相应的附连区域(14a与15a和14b与15b)配合而将翼片固定就位。因此,如图5中所示,在包套(10)被施加至袋(2)的情况下,翼片(12a和12b)紧贴地保持顶端(5),使得当倒置带包装的冷冻甜食用于分配时袋(2)不会从包套(10)掉出。
分配最好通过使用者在顶端(5)和基端(6)附近抓住包套并向上且向内朝着顶端(5)挤压并卷起基端(6)被实现。
在分配后,仅通过向外拉动翼片(12a、12b)就可使附连区域(14a、15a、14b、15b)松开。然后,袋(2)可在制品出口(8)不与包套(10)接触的情况下向上滑动并离开包套(10)。然后,可将袋(2)放置在冷冻机中以便储存。在从冷冻机中取出袋(2)用于下一次的分配场景时,包套(10)于是可如以上所描述地重新施加于袋(2),从而防止使用者在分配期间不得不接触袋(2)的非常冰凉的外壁(4)。
现在将参考下列示例、仅通过示例的方式描述本发明。
示例1
配制了具有不同冰含量(在-18℃条件下计算)和赤藓糖醇量的两种冰淇淋,如表1中所示(数量单位为%w/w)。
表1
配方性质在表2中示出。
表2
1 | 2 | |
冰含量(%w/w) | 36 | 37 |
凝固点降低剂(%w/w) | 31 | 30 |
<M><sub>n</sub>(g mol<sup>-1</sup>) | 214 | 212 |
赤藓糖醇(%w/w) | 1.6 | 2.3 |
通过对根据上述配方制备的混合物进行巴氏灭菌和均质化来制备冰淇淋。使混合物在4℃条件下熟化(aged)过夜,然后在刮面式热交换器(标准冰淇淋冷冻机)中冷冻并通气。控制向冷冻机的空气输入,以产生目标膨胀率100%(实际膨胀率在92与110%之间变化)。控制冷冻,以产生-7℃的目标挤出温度(实际挤出温度在-6与-9℃之间变化)。
将混合物直接挤出到用于饮料且类似于图1中所示的袋的商业食品级袋中。袋壁材料是包含聚对苯二甲酸乙二醇酯、铝、定向聚酰胺和聚乙烯的层压膜。制品出口是内径为22毫米的吸嘴。每个袋的容量为750毫升。通过吸嘴将数量为425g的冰淇淋填充到每个袋中,且然后将盖帽拧紧到位。然后,使袋在鼓风冷冻机中硬化且然后在使用前转移到家用冷冻机(-18℃)中数天。
当从冷冻机中取出袋时,可以发现,袋触摸起来极其冰凉,使得袋仅被保持若干秒就会使触碰变得不舒服。
另一方面,如图4和5所示,通过向袋施加包套,即可舒适地手持袋若干分钟。包套由夹持在LycraTM织物之间的1mm厚的发泡氯丁橡胶制成,并且包套可容易地从袋上移除并重新附连到袋多次。
示例2
除了使用不同的袋之外,以相似于示例1中所描述的方式制备另外的带包装的冰淇淋。袋形状如图3中所示。袋壁材料是包含聚对苯二甲酸乙二醇酯、定向聚酰胺和聚乙烯层但没有铝层的层压膜。制品出口是内径为22毫米的吸嘴。每个袋的容量为400ml。通过吸嘴将数量为230g的冰淇淋填充到每个袋中,然后将盖帽拧紧到位。然后使袋在鼓风冷冻机中硬化且之后在使用前转移到家用冷冻机(-18℃)中数天。
当从冷冻机中取出袋时,由于与示例1的袋相比的袋膜材料的差异和更小的尺寸,所以可以发现,即使不使用包套,袋也便于手持。此外,袋的形状和尺寸允许使用者方便且几乎完全地分配内容物。
