Sucrose invert

Invert sugar is only encountered as a syrup. The fructose in the mixture will not crystallise so attempts to crystallise invert sugar yield dextrose. Invert sugar overcomes one of the big drawbacks of sucrose. Invert... 

The sweeteners used in soft drinks can be divided into two main categories. These are the natural sweeteners, such as sucrose, invert syrups, corn-derived syrups and honey, and the high-intensity sweeteners (artificial sweeteners) such as saccharin, aspartame and acesulfame K. In most fruit juices and many soft drinks, except diet vaiieties, sugars are a major component of the product.

For simplicity we will refer to the "sucrose invert medium" as sucrose.

One way of testing the model is to perform experiments at the centre of the domain. We consider here the results of 3 replicates (polysorbate 80 = 4.0%, propylene glycol = 20%, sucrose invert medium = 55% by volume). A mean value of 3.0 ppm is obtained for the turbidity. This is slightly different from the mean value of the factorial experiment data, but further analysis is necessary before deciding whether or not the model is sufficient for predictive purposes in the experimental region. This problem is therefore developed further in chapter 5.

We take first the full quadratic model and calculate the lines of equal response. As there are 3 variables, the factor space is in 3 dimensions, and to represent this on a 2-dimensional paper surface or computer screen, we need to take slices with one of the variables held constant. Here the polysorbate concentration, X, was chosen as the fixed variable. Taking x, = -1, 0, +1 (real values 3.7, 4.0, 4.3% polysorbate), lines of equal turbidity are plotted in the X2, X plane (propylene glycol, sucrose invert medium), as shown in figure 5.7.

In the first effect water is present at a significantly higher concentration than the solutes viz., sucrose, invert and PPCC), and therefore, the reaction of Fru with water to produce D-fructose predominates. In fact, in dilute solution, prior to evaporation, the above mentioned alternative reactions are unlikely. In later effects, as the concentration of solutes increases, the alternative reactions become more likely, i.e., small amounts of kestoses and difructose dianhydrides may form in the later stages of evaporation if there is any further sucrose hydrolysis.

Sucrose, invert sugar and starch-sugar are introduced at the stage of hopping or before the beer is bottled. 

Analysis of only the simplest sugar mixtures is generally required for pharmaceutical preparations and the subject will be discussed briefly and yet in sufficient detail for undertaking the estimation of simple sugars or mixtures of sucrose, invert sugar and glucose or lactose.
