橡木的作用有哪些，橡木，即櫟屬，是殼斗科 (Fagaceae)的一個屬。櫟屬有600個種，其中450種來自櫟亞屬和150則是青剛亞屬。它們分布在北半球溫和地區(qū)，主要是北美洲。橡木在馬來半島地區(qū)也盛產(chǎn)，其中北美洲以美國賓州的紅橡更為。那么橡木的作用有哪些呢
What are the functions of oak? Oak, or Quercus, is a genus of Fagaceae. There are 600 species of Quercus, 450 of which are from subgenus Quercus and 150 from subgenus Cyclobalanopsis. They are distributed in temperate regions of the northern hemisphere, mainly in North America. Oak is also abundant in the Malay Peninsula, among which the red oak of Pennsylvania is the most famous in North America. What are the functions of oak

橡木廣泛用于裝潢用材和制作家具，在于其優(yōu)良的材質(zhì)性能：橡木重硬紋理直，結(jié)構(gòu)粗，色澤淡雅紋理美觀，力學(xué)強度相當(dāng)高，耐磨損，但木材不易于干燥鋸解和切削。橡木大量應(yīng)用于裝潢材、家具材、體育器材、造船材、車輛材、地板材等。白橡、紅橡的切片也是生產(chǎn)帖面化膠合板的理想用材，其花紋也有直紋和橫紋的區(qū)別，直紋比較好看，也稍貴一些
Oak is widely used in upholstery and furniture because of its excellent material properties: heavy hard oak, straight texture, coarse structure, light color, beautiful texture, high mechanical strength, wear resistance, but the wood is not easy to dry, sawn and cut. Oak is widely used in decoration materials, furniture materials, sports equipment, shipbuilding materials, vehicle materials, floor materials and so on. The slicing of white oak and red oak is also an ideal material for veneering plywood. The pattern of white oak and red oak is different from that of cross grain. The straight grain is more beautiful and the price is slightly higher
橡木的多孔性允許貯藏在橡木酒桶中的葡萄酒有一定程度的蒸發(fā)和氧化，但不于引起葡萄酒變質(zhì)。一年中，一個59加侖(225升)的橡木酒桶中會有5?6?加侖(20.824.6升)葡萄酒蒸發(fā)，而其中大部份是酒精和水，這樣會留下更多的芳香族化合物使得葡萄酒更加美味。
The porosity of oak allows the wine stored in oak barrels to evaporate and oxidize to a certain extent, but does not cause wine deterioration. Five to six (20.8 to 24.6 liters) of wine evaporate in a 59 gallon (225 liter) oak barrel, most of which is alcohol and water, leaving more aromatic compounds to make the wine more delicious.
橡木中所含酚類會和葡萄酒反應(yīng)產(chǎn)生香味和甜味。同時葡萄酒中的鞣質(zhì)也會發(fā)生變化，橡木木質(zhì)素中的可水解的鞣質(zhì)稱為鞣花單寧，可防止葡萄酒氧化。
Phenols in oak react with wine to produce aroma and sweetness. At the same time, the tannin in wine will also change. The hydrolyzable tannin in oak lignin is called ellagic tannin, which can prevent wine oxidation.
在葡萄酒發(fā)酵時可以盛放在橡木桶中，在發(fā)酵之后也可以在其中繼續(xù)陳化或成熟。在橡木酒桶中發(fā)酵的白葡萄酒相對會擁有更白的色澤和更柔軟的口感。橡木酒桶中的葡萄酒通常會被描述為有焦糖、奶油、煙熏和香料等等各種風(fēng)味，這些風(fēng)味大多數(shù)都是在葡萄酒注入酒桶中的頭一個月中增加的。
The wine can be placed in oak barrels during fermentation and can be aged or matured after fermentation. White wine fermented in oak barrels has a whiter color and softer taste. Wine in oak barrels is often described as having caramel, cream, smoke and spices, most of which are added in the first month of the barrel.
