Emulsion in mayonnaise

History[ edit ] Standard ingredients and tools to make mayonnaise A "mayonnaise de poulet" is mentioned by a traveler to Paris inbut not described. A common theory is that it is named for Port Mahon in Menorcain honor of the 3rd Duke of Richelieu 's victory over the British inand in fact the name "mahonnaise" is used by some authors. But the name is only attested long after that event.

Management in Different Industry Sectors5. The shelf life could be increased to 49 days by addition of citric acid or sodium citrate and propyl gallate in the oil phase and EDTA and ascorbic acid in the aqueous phase.

Despite this improvement in oxidative stability, production of mayonnaise made with Emulsion in mayonnaise oil only does not seem to be a suitable strategy.

A more realistic strategy is to substitute only part of the vegetable oil with fish oil. The following mechanism was suggested to explain this finding: These components are located at the oil-water interface in mayonnaise.

When pH is decreased to 4. Thus, iron becomes more active as a catalyst of oxidation. Thus, mayonnaise with small droplet sizes oxidised faster in the initial part of the storage period than in mayonnaise with larger droplets, whereas no effect of droplet size on oxidative flavour deterioration was observed in the later part of the storage period.

The following mechanism to explain these findings was suggested: In the later stage, oxidation proceeds inside the oil droplet and therefore the droplet size is less important. The ability of a range of different antioxidants to prevent lipid oxidation in this type of fish oil enriched mayonnaise has also been evaluated.

Both propyl gallate and gallic acid acted as prooxidants. The prooxidative effects of propyl gallate and gallic acid were suggested to be due to their ability to reduce metal ions to their more active form, e. Likewise, ascorbic acid and ascorbyl palmitate were also shown to act as pro-oxidants, and the proxidative effect of ascorbic acid increased with increasing concentrations.

Additional experiments on the oxidative stability of fish oil enriched mayonnaise with ascorbic acid added indicated that ascorbic acid induced iron release from the oil—water interface into the aqueous phase and this effect of ascorbic acid was strongest at low pH 3.

It was proposed by the authors that iron release from the interface was a result of broken ion bridges between iron and egg yolk proteins, whereby iron ions become accessible as initiators for the lipid oxidation.

This finding was probably due to the properties described above for ascorbic acid alone in fish oil enriched mayonnaise. Mixtures of tocopherols were found to have a concentration dependent effect in fish oil enriched mayonnaise. Moreover, their effect also depended on whether a water or oil soluble tocopherol mixture was used.

In contrast, prooxidative effects were observed at higher concentrations. Addition of a tocopherol mixture as a water soluble preparation in mayonnaise generally exerted prooxidative effects on fishy flavour.

These observations suggest that tocopherol does not have an unequivocal effect on fishy odour and flavour in mayonnaise. The poor effect of tocopherol observed in mayonnaise may be a result of the high levels of tocopherols already present in the oils used in the mayonnaise oils: As described above, metal-catalysed oxidation is an important initiation mechanism for lipid oxidation in fish oil enriched mayonnaise and it can therefore be expected that metal chelators would be able to prevent oxidation.

However, among the metal chelators evaluated lactoferrin, phytic acid and EDTA only EDTA efficiently prevented lipid oxidation and thereby off-flavour formation in this food system Fig.

The antioxidative effect of lactoferrin seemed to be concentration dependent, since it had a slight antioxidative activity at low concentrations and showed prooxidant activity at high concentrations.May 23,  · To make mayonnaise, you need to slowly beat oil into egg until an emulsion forms — that is, the oil molecules are uniformly dispersed in the egg and then hold there.

Emulsions and Emulsifiers It is common knowledge that oil and water don’t mix. If you try to mix them Mayonnaise is a perfect example. Mayonnaise contains about 80% oil But why does mayo exist as an O/W emulsion while a vinaigrette, containing the same ratio of oil to vinegar, exists as a W/O emulsion?.

Mar 23,  · Skip the store-bought sauce and learn how to mayonnaise right at home! A simple combination of eggs, oil, and seasonings is all you need to create a smooth, rich and creamy sauce. It only takes 10 minutes or less to make the popular condiment.

To get the emulsion started to create a thickened sauce, the most important 5/5(6). Mayonnaise is an example of a permanent emulsion, consisting of egg yolks and oil. Egg yolks and oil would not naturally mix together, but by slowly whisking the oil into the egg yolks, the two liquids form a stable emulsion that won't separate.
