A sucrose solution with an apparent specific gravity ( 20 °/ 20 ° C ) of 1. 040 would be 9. 99325 ° Bx or 9. 99359 ° P while the representative sugar body, the International Commission for Uniform Methods of Sugar Analysis ( ICUMSA ), in favor of mass fraction, would report the solution strength as 9. 99249 %.

Equilibrium sedimentation uses a gradient of a solution such as cesium chloride or sucrose to separate particles based on their individual densities ( mass / volume ).
For instance, when using sucrose to prepare density gradients, one can carefully float a solution of 40 % sucrose onto a layer of 45 % sucrose and add further less dense layers above.

The sucrose is hydrolysed into glucose and fructose, with glucose being a reducing sugar, which in turn tests positive with Benedict's solution.
One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% w / w ) ( strictly speaking, by mass ).
If the solution contains dissolved solids other than pure sucrose, then the ° Bx only approximates the dissolved solid content.
It is important to point out that neither wort nor must is a solution of pure sucrose in pure water.
For example, the refractive index of a sucrose solution of strength less than 10 ° Bx is such that a 1 ° C change in temperature would cause the Brix reading to shift by about 0. 06 ° Bx.
When a sugar solution is measured by refractometer or densitometer, the ° Bx or ° P value obtained by entry into the appropriate table only represents the amount of dry solids dissolved in the sample if the dry solids are exclusively sucrose.

Just like fat, high levels of fructose and / or sucrose induce insulin resistance in rats, and, just like with fat, this insulin resistance is ameliorated by fish oil supplementation.
There has been recent speculation that the increase in such carbohydrates since sucrose ( table sugar — half glucose and half fructose ) became available in quantity after about 1700 with the discovery of a practical source ( sugar cane ), accounts for some of the diseases of civilization, including diabetes.

It is used as a sweetener in the food industry with a sweetening power that of sucrose and is sometimes added to yogurts as a prebiotic.
Sucrose indirectly produces a positive result with Benedict's reagent if heated with dilute hydrochloric acid prior to the test, although after this treatment it is no longer sucrose.
Threshold tests for sucrose ( sweet ), citric acid ( sour ), sodium chloride ( salty ), and quinine or caffeine ( bitter ) are frequently performed with natural stimuli.
The juices ( containing 10-15 percent sucrose ) are collected and mixed with lime to adjust pH to 7, prevent decay into glucose and fructose, and precipitate impurities.
The lime and other suspended solids are settled out, and the clarified juice is concentrated in a multiple-effect evaporator to make a syrup with about 60 weight percent sucrose.
sucrose and apparent
Types of sugar used include sucrose, dextrose, and inverted sugar to control apparent sweetness.

A vintner could measure the specific gravity of his must and enter the Brix table to find the must ° Bx value i. e. its % sucrose w / w.
Many other compounds are dissolved as well but these are either sugars, which behave very similarly to sucrose with respect to specific gravity as a function of concentration, or compounds which are present in small amounts ( minerals, hop acids in wort, tannins, acids in must ).
Those workers measured true specific gravity reference to water at 4 ° C using, respectively, 17. 5 and 20 ° C, as the temperature at which density of the sucrose solutions was measured.
