Over the past years non-dairy whipping creams have become increasingly popular due to a number of benefits, such as reduced fat content, better cost-in-use calculations and better foam stability, which makes them easy to use and hence attractive bakers and caterers. However, producing successful imitation whipping creams requires not only the right fats but the right combination of emulsifiers and stabilisers. Whipped creams are widely used for cooking in households and in the catering sector, especially for desserts and cake decorations.

The whipped creams may be in the form of dairy whipping cream or imitation whipping cream. These vegetable fat based products are called e. The whippability of dairy whipping cream depends on the fat content as well as on the fat globule structure. Further, the original fat globule structure should be maintained, meaning that the cream, in contradiction to most other dairy products, are not homogenised. If high shear is applied during processing the whippability is diminished, which can, however, be re-established by application of emulsifiers.

Imitation whipping cream is a liquid oil in water emulsion, which is whipped into a stable foam. The foam is air bubbles dispersed in the serum phase stabilized by destabilized fat. Imitation whipping cream normally contains vegetable fat, milk proteins, sweeteners, water and emulsifiers and stabilisers. The milk protein is often sodium caseinate as whey proteins tend to induce agglomeration in the liquid cream during storage. As the fatty acid composition of the vegetable fat influence the viscosity of the liquid cream as well as the foam structure, firmness end eating properties, the manufacturer must ensure that the fat chosen is suitable for the application.

Likewise the choice of emulsifier and stabiliser has great importance for the quality of the cream. Emulsifiers and stabilisers are important in the formation of a stable liquid emulsion and in the whipping process for formation of a stable foam with a high overrun. This will be described in more details below.

Imitation whipping cream is commonly produced by means of the UHT-process as this ensures a long shelf life of the product. With the right choice of emulsifiers and stabilisers the cream may be stored at room temperature. The design of the UHT-plant should be downstream with 2 stage homogenisation ensuring the formation of a stable emulsion. Emulsifiers are surface active ingredients due to their hydrophilic-lipophilic properties.

In competition with the proteins it locates in the interface between the oil droplets and the serum phase, or in the case of foam, in the air serum interface. Hereby it lowers the interfacial tension between two phases. Proteins and emulsifiers also interact altering the fat globule membrane and its emulsion stability and resistance towards mechanical interactions. The effect depends on the hydrophilic and lipophilic groups as well as the ionic properties.

The main functionality of emulsifiers in imitation cream is to destabilize the fat globule membrane covering the fat globules formed during homogenisation of the cream. During storage of the liquid cream the proteins covering the fat globule are displaced by emulsifiers. Hereby agglomeration and partially coalescence of the fat globules is facilitated. This is important for the structure formation and air cell distribution formed during whipping.

Further emulsifiers are important for the stability of the formed air cells i. For imitation whipping cream there is a conflict between formation of a stable liquid emulsion with good storage stability and an easy whippable emulsion with good foam stability.

During whipping the fat globules needs to be broken and release fat which then agglomerates and coats the air cells and thereby builds a stable foam skeleton. Lactem is often used in combination with mono- and diglycerides. Mono- and diglycerides are added for its destabilizing effect on the emulsion improving the foam stiffness and stability, an effect increasing with increased iodine value of the emulsifier.

This viscosity increase may be inhibited by adding the more polar emulsifier lecithin, or an anionic emulsifier like diacetyl tartaric acid esters of mono- and diglycerides Datem or sodium stearolyl lactylate SSL acting as strong oil in water emulsifiers. Hereby the negative net charge of the fat globules is increased and the emulsion stability increased.

The increased emulsion stability counteracts the whipping properties, which is why a balance in the use of different emulsifiers is important. Emulsifiers are used in combination with stabilisers.

Stabilisers are hydrocolloids which bind and immobilise water. In imitation cream stabilisers are working in water phase improving the emulsion stability in the liquid cream, improving the foam stiffness and preventing drainage in the whipped cream. By combining the emulsifiers and stabilisers in different levels imitation whipping creams with good piping definition but different body and mouth feel but can be produced.

Both of the mentioned emulsifier blends include Lactem as the whipping agent. The cream was produced by means of UHT. After whipping in a Hobart whisper the hardness was analysed in a TaXT2 texture analyzer. This even at the same overrun in the cream as demonstrated in Figure 2. This is an important parameter for employees in catering and bakeries as they are hand-ling more tasks at the same time.

Here flexibility is a must. In Figure 4 results of the hardness analysed by means of the TaXT2 texture analyzer are shown and it is evident that the measured hardness is at the same level for the standard and high overrun solution. This opens an opportunity for cost saving in e. However, sometimes a protein-free product is requested either for nutritional or for technological reasons. As a technological advantage talking for protein-free imitation cream it can be mentioned that the cream is pH stable.

In confectionary applications fruit or fruit flavoured ingredients are often mixed into the cream. If proteins are present the risk of denaturation of the proteins is present resulting in a separated product with texture and sensory properties which will not be accepted by the consumers.

As the protein, when available, is an important functional ingredient in the emulsion formation and structure building, the types of emulsifiers and stabilisers have to be modified and other ingredients added in production of protein-free alternatives to obtain the same overrun and stability in the liquid cream as well as in the whipped product. This combined emulsifier and stabiliser solution makes it easy for the manufacturer to produce a high quality protein free UHT imitation whipping cream.

The emulsifier uses polyglycerol esters of fatty acid PGE as the main emulsifier. PGE is a hydrophilic emulsifier improving whippability and foam stability of emulsions. As shown above emulsifiers and stabilisers play a big role in creating an imitation whipping cream with the qualities demanded by bakers, caterers and the end consumer. Technical article.

ADEX Emulsifiers

The asphalt emulsions were prepared using modified lignin amines as cationic emulsifiers. The effect of types and dosage of lignin cationic emulsifiers on the preparation and storage stability of asphalt emulsions were discussed by measurement of average particle diameter and Zeta potential of emulsions. The experiments show that the higher the surface activity of emulsifiers was, the smaller the average particle diameters of emulsions became. With the increasing of dosage of emulsifiers, the average particle diameters of emulsions descended. The storage stability of emulsions was improved distinctly when the lipophil dodecyl group was introduced into emulsifiers, which was attributed to good surface activity and enhanced mechanical strength of interfacial membrane for the alkyl chain of dodecyl group could be inserted in the asphalt particles.

Emulsifiers, also known as surfactants, are often added to processed foods to improve stability, texture, or shelf life. The amphiphilic molecules function by assisting the dispersion of mutually insoluble phases and stabilizing the resulting colloids, emulsions, and foams. Emulsifiers can interact with other food components such as carbohydrates, proteins, water, and ions to produce complexes and mesophases. These interactions may enhance or disrupt structures and affect functional properties of finished foods. In baked products, emulsifiers contribute to secondary functionalities, such as dough strengthening and anti-staling. Mayonnaise, for example, is stabilized by egg yolk. This book can serve as both a guide for professionals in the food industry to provide an understanding of emulsifier functionality, and a stimulus for further innovation. Students of food science will find this to be a valuable resource. Richard W.

So how do they help create a stand-out alternative to dairy whipping cream? So, how is it possible to produce a dairy-free alternative without compromising on ease of whipping and foam stability? The answer lies in getting the mix of emulsifiers and stabilizers just right. Dairy-free whipping creams are becoming commercially popular because of their improved functionality and the significant cost advantages they offer. They allow food manufacturers to reduce the fat content of recipes, catering to an increasingly health-conscious market. And from a cost perspective, dairy-free whipping creams offer better cost-in-use calculations compared to their dairy counterparts because vegetable fat is a lot more affordable than dairy fat. As a result, there has been an increase in the availability of vegetable fat-based creams, often referred to as non-dairy, dairy-free, imitation, or topping creams and used frequently in desserts and for cake decorating. Dairy-free whipping cream is a liquid oil-in-water emulsion, which can be whipped into a stable foam. The foam consists of air bubbles dispersed in a serum phase.

An emulsion is a mixture of two or more liquids that are normally immiscible unmixable or unblendable. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid the dispersed phase is dispersed in the other the continuous phase.
