Powder drinks

Powder drinks form an insignificant part of the UK market but have substantial sales in the USA. Their formulation closely minors that of liquid soft drinks, with the exception of water content. The components that do differ are  

Production must be carried out in an area of controlled (low) humidity. To prevent separation after blending all components should be as similar as possible in particle size and bulk density. The ingredients must be sieved before addition and it is often preferable to prepare a pre-blend of some ingredients to facilitate the addition of small mass items and mixing in. Mixing is earned out in ribbon blenders and can be on either a batch or a continuous basis. Packaging is in sachets or jars. 

Long-term stability is better than for liquid drinks and powder drinks are ideal for vitamin fortification because of their slow decay rate in the absence of water and without ingress of air. 

Effervescence can be achieved by the incorporation of sodium bicarbonate, but care needs to be taken to avoid saltiness. 

Normal dose rates are about 100-120 g of powder to make a litre of sugar sweetened drink and as little as 10-20 g for low-calorie drinks and unsweetened drinks where the consumer adds sugar to taste.

Uses. Commercial monocalcium phosphate is available as both the anhydrous and the monohydrate salts. Most uses are based on acidic properties. Monocalcium phosphate is used to control acidity in powdered drink mixes, as an ingredient in effervescent tablets, as a plastics stabilizer, and in ceramics. Its single largest appHcation is as a leavening agent in bread, cake mixes, and self-rising flour. 

NMR is an incredibly versatile tool that can be used for a wide array of applications, including determination of molecular structure, monitoring of molecular dynamics, chemical analysis, and imaging. NMR has found broad application in the food science and food processing areas (Belton et al., 1993, 1995, 1999 Colquhoun and Goodfellow, 1994 Eads, 1999 Gil et al., 1996 Hills, 1998 O Brien, 1992 Schmidt et al., 1996 Webb et al., 1995, 2001). The ability of NMR to quantify food properties and their spatiotemporal variation in a nondestructive, noninvasive manner is especially useful. In turn, these properties can then be related to the safety, stability, and quality of a food (Eads, 1999). Because food materials are transparent to the radio frequency electromagnetic radiation required in an NMR experiment, NMR can be used to probe virtually any type of food sample, from liquids, such as beverages, oils, and broth, to semisolids, such as cheese, mayonnaise, and bread, to solids, such as flour, powdered drink mixes, and potato chips. 

In this work, a simple and fast analytical procedure is proposed for the simultaneous determination of Apt, Ace-K and Sac in commercial products (powder drinks and colored beverages). The sweeteners were extracted n-butanol solution and the absorption spectra were recorded between 190-300 mn against blanc solution and the absorbance values were taken 5 nm interval. The method involves the use of 27 standard mixtures of the three compounds assayed, considered at three concentration levels and measured of samples in 0.1 N H PO solution. 

A calibration set containing between 7-9 gg mL of Apt, 1-3 gg mL" of Ace-K, and 2-4 gg mL of Sac was used. The designed and optimized training set of calibration was applied to the determination of three sweeteners of several synthetic mixtures. The method was also applied to commercial drinks and satisfactorily results were obtained. The procedmes do not require any separation step for colorless sample (powder drink), but only an extraction step for colored beverages (powder and liquid) was used. The effect of cyclamate (CA) and ascorbic acid (AA) was also investigated. 

In this paper, for the first time a chemometric model based on the application of a partial-least-squares (PLS-2) method is proposed fort he resolution of a complex artificial sweetener mixture Ace-K, Sac, Apt) and Vit C have been tested to check to abilities of PLS optimized model. Also the possibility of analyzing powdered drinks (Sahlep and Tang) are shown (Fig. 33.1). 

Powdered drinks (Sahlep and Tang) samples were purchased from local markets. 

Powdered drink sample Sahlep) It contains three artificial sweeteners Apt, Ace-K, Sac. An accurately weighted amount of 0.05 g powdered drink (Sahlep) was transferred to 100 mL volumetric flask. The flask was filled up 0.1 N HjPO and agitated 5 min. The solution was diluted 100 mL with 0.1 N H3PO. ... 

Powdered drink sample (Tang) It contains three artificial sweeteners, Apt, Ace-K, Sac, Vit C, and food colors (allura red, titanium dioxide, brilliant blue, tartrazine). 

For extraction of synthetic food colors from sample 0.1 g powdered drink sample was dissolved in 20 mL 0.1 N HjPO solution. 

Extracts dried on to a water-soluble base are useful in the preparation of powdered drinks. Soft extracts tend to contain about 70% solid matter and can be mixed into a slun y with the substrate and spray-dried or dried in a vacuum oven. The substrate is usually essential to prevent the dried extract from reabsorbing moisture and turning back into a hard or sticky mass. The dried extracts can be dry-blended with other ingredients in a powdered drink formulation. 

A good starting point is always the supplier s own specification, which can be expanded to include requirements specific to the required end use (for example particle size for powdered drink ingredients). 

Rice bran oil can be extracted from either stabilized or unstabilized bran. The by-product resulting from stabilized bran extraction is suitable for human food use. Stabilized rice bran is currently being used in baked goods, energy bars and protein fortification of powdered drink formulations. 

A. Quantitative Determinations. One of the three isocratic separations could also be used for a quantitative determination of the amounts of FD C Blue 1 and Red 40 present in the powdered drink mix. A spectrophotometer would be needed. After scanning to determine the best wavelength for the analysis of each dye, measurements on standard solutions could be used to construct a calibration curve. The isocratic separation could then be performed, and the entire band containing each dye could be collected and diluted accurately to an appropriate volume. With the volume of the eluted bands known, the mass of dye can be calculated. 

Solid-liquid Sweetened powder drink contains sugar and other solid ingredients in water. 

If you drink coffee, you know the difference between a strong cup of coffee and a weak cup of coffee. If you don t drink coffee, I am sure you can recall having a glass of weak iced tea, or some other powdered drink mix. When we talk about the strength of one of these drinks, we are really talking about the concentration of a solution. We will be learning more about concentration later on, but for now you should remember that you could vary the concentration of a mixture but not of a compound. 

Why do drink mixes come in powder form What would happen if you dropped a big chunk of drink mix into the water Would it dissolve quickly Powdered drink mix dissolves faster in water than chunks do because it is divided into smaller particles, exposing more of the mix to the water. See for yourself how particle size affects the rate at which a substance dissolves.
