明媚的夏日午后，一场家庭烧烤在庭院中悄然展开。孩子们追逐玩耍，大人们翻动着烤架上的食物，香气在阳光下四处飘散。看似寻常的夏日欢聚，背后却藏着气体技术的默默守护。无论是食材的保鲜运输，火候的精准掌控，还是饮品的口感稳定，工业气体正用看不见的方式，为我们的夏日生活注入便利与美味。

美味烧烤的“隐形帮手”

有人偏爱木炭带来的烟熏香气，也有人青睐气体烧烤炉所带来的快捷、均匀与无烟加热。而支撑这种“干净烧烤”体验的背后，是丙烷（C₃H₈）提供的稳定、高效热能，轻松满足各种家庭烧烤的需求。

留住食物的色香味

无论是包装还是冷链运输，氮气（N₂）和二氧化碳（CO₂）都能为食材保驾护航，它们减少、维持低温，延缓变质，让食物在烧烤时呈现出最佳口感与风味。这些看不见的“保鲜卫士”，正在多个关键环节中发挥作用。例如，借助惰性气氛包装，肉类在运输和储存过程中依旧保持色泽鲜亮，直到拆袋那刻依然令人垂涎。香料的风味保留则得益于低温液氮（N₂）的应用，它能在研磨过程中迅速封存香气，避免挥发流失。液氮（N₂）还能为食品加工带来更高灵活性，例如在巧克力裹冰淇淋棒的制作中，它可使热巧克力瞬间凝固，形成酥脆脆皮口感。二氧化碳（CO₂）亦可助力面包制作——在面团的揉捏与定型过程中，帮助维持最佳温度，进而提升结构稳定性与口感表现。

饮品清爽，尽在气体调控

一杯啤酒的绵密泡沫、一瓶果汁的新鲜口感、一杯清水的通透纯净，这些看似自然的清爽体验，都有工业气体的一份功劳。二氧化碳（CO₂）是啤酒酿造中不可或缺的气体，它赋予啤酒独特的清新刺激口感与细泡沫。酿酒师们还会在葡萄酒储罐顶部填充氮气（N₂）、二氧化碳（CO₂）或氩气（Ar）等惰性气体，以防止氧化、保留果香。瓶装果汁在灌装过程中会滴入少量液氮（N₂），它迅速汽化膨胀，使PET瓶精准定型，防止泄露，同时维持果汁的新鲜度。即便是日常饮用水的品质，也少不了气体的参与：二氧化碳（CO₂）可调节水的硬度，臭氧（O₃）与氧气（O₂）则能清除杂质，净化水质，使自来水清澈甘冽。

从厨房到日用品

日常生活那些习以为常的“精致细节”，其实都离不开气体的参与。例如，玻璃杯杯口之所以光滑细腻，不割嘴唇，是因为出厂前会经过熔融抛光处理，而处理过程中注入纯氧（O₂）可提升火焰温度，加快打磨效率，提升成品质量。瓷器的烧制同样依赖氧气（O₂）提升热效率并减少排放，使整个工艺过程更加节能环保。刀具的锋利与耐久性也离不开气体技术：通过液氮（N₂）冷处理，刀片结构得以强化，即使在高频使用下仍能保持形状不变。焊接刀柄与刀刃时，乙炔（C₂H₂）和纯氧（O₂）同样发挥关键作用，为精细连接提供能量支持。

精准焊接，打造更安全耐用的产品

在夏季常用的户外装备中——如自行车、烧烤炉、遮阳篷或金属支架等，焊接工艺直接决定了其结构强度与使用寿命。梅塞尔提供的三组分混合气体（如氩气（Ar） + 氧气（O₂） + 二氧化碳（CO₂）），可在焊接过程中确保焊缝紧致、平滑、美观，为户外使用提供坚固、持久的质量保障。

结语

从餐桌到日用品，从口感到品质，工业气体正悄然参与并塑造着我们夏日生活的每一个美好细节。梅塞尔始终致力于通过创新的气体解决方案，支持每一次味蕾的享受，每一场聚会的顺利进行，甚至每一个看似平凡的日常时刻。这个夏天，有 “气体”的陪伴，美好更加可期。

Without gases a barbecue on a beautiful summer's day wouldn't be half as nice: anything that is tasty, aesthetic or practical almost always owes its pleasant properties to one or more gases. Gases for Life are omnipresent here too.

Summer delicacies

As soon as the temperatures start to rise and the sun is still shining in the evening the barbecue season begins. In summer many people like to spend their evenings socializing with friends or family, enjoying delicious food and cool drinks. Opinions differ when it comes to the question of charcoal or gas barbecues. Some don't want to do without the aroma of charcoal. Others appreciate the fast, even and smoke-free heating of the gas barbecue thanks to propane.

Nitrogen and CO₂protect the food from oxidation, cool it during transportation and perform other useful tasks to ensure that the taste, freshness and consistency of the food are pure enjoyment. Thanks to the inert gas packaging the meat remains appetizing until the grill master swings the tongs. The fact that the spices have a strong flavor is not least thanks to cryogenic nitrogen: it helps to preserve the aromas during grinding.

Dry ice keeps sausages and fish cool on their way from the producer to the supermarket. It also ensures the optimum dough temperature for kneading and shaping baguettes. Ice cream on a stick only gets a crispy thin coating of chocolate through cryogenic nitrogen because the gas causes the warm, soft chocolate to solidify immediately after contact with the ice cream.

Refreshing drinking pleasure

The beer tastes tangy and forms a beautiful head because CO₂is added to it in the brewery. To ensure that the wine does not oxidize in the tank and retains its fruity aroma, the winemaker fills the headspace with an inert gas such as CO₂, nitrogen or argon. A drop of liquid nitrogen is added to the juice bottle during bottling. Because it evaporates immediately and expands the PET bottle retains its shape and the juice is protected from spoiling. Even tap water would not be as we know it without gases. Among other things, CO₂provides the necessary hardness, while oxygen and ozone remove unwanted substances so that it flows fresh and clear from the tap.

And everything that goes with it

Why we don't cut our lips when drinking from glasses: The rim surfaces of the finished glasses are slightly melted to make them smooth and the edges round. Smoothing the edges has to be done very quickly, which is why pure oxygen (O₂₎is added to the special burners to increase the temperature. This also helps to save fuel and reduce emissions. O₂also makes ceramic firing much more efficient and environmentally friendly.

Without gases, knife blades would not be as sustainably sharp and attractive as we know them. Thanks to the cold treatment of metals with cryogenic nitrogen, they remain stable without changing their shape in the long term. Acetylene and pure oxygen are used to solder the handle and blade. Messer's three-substance mixtures - for example of argon, oxygen and CO₂- ensure perfect weld seams on the steel parts of bicycles, barbecues, awnings and parasols.

For more than 125 years, Messer, the today’s world's largest privately owned company for industrial gases, medical gases, specialty gases, and gases for electronics, committed to its guiding principles of safety, focus on customers and employees, responsibility for our society, sustainability, trust, and respect.
