Emulsifiers

The HLB values can predict the behavior of an emulsifier so they could be used as W/O emulsifiers wetting agents O/W emulsifiers detergents or solubilizing Clearly these numbers are not precise but combined with the experience of the food technologist they can be a useful help to narrow the field of possible emulsifiers used

Effects of Selected Polysorbate and Sucrose Ester

Emulsifiers with HLB values of 3 5 to 6 tend to be the most suitable for water in oil (W/O) emulsions and those with HLB values from 8–18 are best suited for oil in water (O/W) emulsions [3 8] Most commercial emulsifiers especially sucrose esters are mixtures of mono- di- and triesters

Sucrose Esters (for Food)

Sucrose esters of fatty acids commonly known as sucrose esters and sucrose oligo esters are a unique group of emulsifiers Sucrose esters are obtained by esterifying sucrose with methyl fatty acids By varying the degree of esterification of the sucrose molecule it is possible to obtain emulsifiers with HLB values ranging from 1 up to 16

Lecithin Applications

Hydophilic (higher HLB) lecithin products promote wetting of fatty powders Particle size needs to be considered Smaller particles with larger surface area may require up to 2% lecithination whereas improved wetting properties of larger particles can be accomplished at up to 0 25%

Overview of Food Emulsifiers

Synthetic emulsifiers have only come into wide commercial use in the second half of the twentieth century Their development was driven by the processed food industry which needed shelf-stable products for distribution through mass-market channels For example creamy salad dressings may be stored for up to a year without visible separation Other factors such as rancidity are now more

HLB Scale

The HLB scale is very relative scale the number values of the HLB Scale don't necessarily give insight into the properties of a surfactant just their relative hydrophilicity compared to other surfactants The That said the HLB Scale is widely used in industry To summarize: The HLB Scale ranges 1-20 Surfactants with higher HLB numbers (greater than 10) are more hydrophilic Surfactants

Emulsifiers

Emulsifiers Emulsifiers are used to stabilise oils fats and waxes in the form of fine droplets in water (= to emulsify) Different emulsifiers are used and often also a combination of several emulsifiers depending on the oil fat or wax to be emulsified and on the stability requirements of the emulsion

HLB – The Easiest Way to Create An Emulsion

Total Req'd HLB = 7 25 You can now select emulsifiers to match the required HLB of the oil phase and create an emulsion A blend of high and low HLB surfactants is often used to achieve the desired value in part because of demonstrated effectiveness and efficiencies in packing at the interface The HLB for the surfactant blend is calculated

Emulsifiers for Good

Polyglycerol Esters of fatty acids (PGE) are a broad class of food emulsifiers with a tunable polarity due to the degree of polymerization of the polyglycerol part in addition to the effect of the specific fatty acid used during synthesis This gives access to a wide range of HLB values
