有关,但不完全是。

以前论坛中关于糖度的帖子不少楼主可以搜索一下
以下是在网上找的
糖度【とうど たう―】:食品等所含的糖分之百分率(%)。
Brix is primarily used in fruit juice, wine making and the sugar industry.
Plato is primarily used in brewing.
[BRIHKS] Named for A. F. W. Brix, a nineteenth-century German inventor, the Brix scale is a system used in the United States to measure the sugar content of grapes and wine. The Brix (sugar content) is determined by a hydrometer which indicates a liquid's specific gravity (the density of a liquid in relation to that of pure water). Each degree Brix is equivalent to 1 gram of sugar per 100 grams of grape juice. The grapes for most table wines have a Brix reading of between 20? to 25? at harvest. About 55 to 60 percent of the sugar is converted into alcohol. The estimated alcohol that a wine will produce (called potential alcohol) is estimated by multiplying the Brix reading by 0.55. Therefore, a 20? Brix will make a wine with about 11 percent alcohol.
糖度計/儀Brix Mete用來測量與糖有關的溶液,如水果汁、軟飲料、酒等, 確定食品、飲料的糖含量以及水果的最佳成熟期,或延伸使用在所有工業的化學溶液的濃度測量和溶液配製,如切割液、磨削液和電鍍液等等。

关于“白利糖度”( Brix)
  《英汉农业科技词典》(袖珍本,1981 年6 月第一版) 中, 收有一个条目:“Brix spindle 白利糖度计”。顾名思义,用它测出的度数,当然是“糖”的浓度。美国柑桔业界两大刊物之一———在加利福尼亚州出版的《Cit rograph》1979 年2 月号第73 页载:“Brix 这个词语,原本的定义是‘按重量计算的蔗糖百分数’,而柑桔行业使用Brix 这个词语,则用
以表示‘可溶性固形物总量的百分数’,在此,可溶性固形物包括柠檬酸和维生素C 以及全糖量。&&佛罗里达州包装(或装罐) 供用户食用的, 是白利45°(45 %可溶性固形物———原文注) 的浓缩品”。从上面这段话,可知Brix 有两种含义: ①本义,指(液体中)“糖”的百分浓度。②美国柑桔行业用语,指“全部可溶性固形物”含量百分率。

收藏 查看&糖度本词条缺少概述、信息栏、名片图,补充相关内容使词条更完整,还能快速升级,赶紧来吧! 糖度是表示糖液中固形物浓度的单位,工业上一般用白利度(&BX)表示糖度,指的是100克糖溶液中,所含固体物质的溶解克数。通常利用糖液的折光性质,用带有蔗糖百分含量刻度的折光仪类的测糖计来测量糖度。如果被检液中含有其它可溶性非蔗糖成分时,其指示值不能表明真正蔗糖的百分含量,称为含量。由于蔗糖水溶液具有旋光性,所以也可利用旋光仪测定其糖度。
溶液的浓度也可用密度法来表示,即用密度计测定。工业生产中盐水的浓度常用波美密度计(Baume′或°Be′)测定;糖水的浓度则用糖度计(Sacchrometer)、波林糖度计(Balling)或白利糖度计(Brix)测定,其中最常用的是白利糖度计,波林糖度计则主要在欧洲使用。为了使用方便,测定糖液用的3种密度计的标度完全一致,均直接表明了糖液浓度的质量百分率。
相对密度是任何溶液的质量和同容积水的质量的比值,它随温度变化而变化,因此测定时必须校正温度。波美密度计、3种糖度计在使用时也必须校正温度。波美密度计种类繁多,我国市场出售的是在15℃标准温度下标刻的“合理”密度计。所谓“合理”即它的0°Be′和15℃时水的密度相当,66°Be′和浓硫酸的密度1.8429相当,而食盐浓度为10%(质量分数,本章均以此表示)时,它的标度正好为10°Be′,因此在0~10°Be′间等分成10格,每格大致相当于1%食盐溶液。
各种糖液密度计上每一表度相当于1%蔗糖溶液的质量百分率。即使糖的种类不同,只要浓度相同,它们各自的相对密度就会非常接近。例如每100mL含糖量为10g的糖液,相对密度(20/4℃)几乎都等于1.0386,因此,糖液密度计可用于测定任何糖溶液的浓度。不过为了准确起见,每支糖度计的标度范围以10°糖度(即浓度变化为10%)为宜。波美计标度由于能转化为密度读数,所以也可用以检测糖水浓度,但从该表上不能直接读得糖液浓度百分率,需要进行转换。
现在也常用折光仪测定糖液可溶性固形物的含量。纯糖溶液内可溶性固形物全为糖类,故能测定糖液浓度。它和密度计一样,使用时同样要注意温度的校正。
