Eggs, milk, soya: allergen advice for caterers
An egg allergy is particularly common in babies and young children, so if you run a venue that is popular with families it’s particularly important to be aware of the risks and offer safe alternatives.
Many egg-based meals and ingredients are easy to identify such as mayonnaise and quiche. However, there are some more hidden forms of eggs. For example, it’s trickier to spot egg in a glaze on pastry or in some types of pasta.
Look out for:
- Egg proteins such as albumin, ovalbumin, globulin, ovoglobulin, livetin and ovomucin which are used as stabilisers or preservatives in processed food
- Lysozyme is an enzyme that can come from eggs. It acts as a preservative and can be found in tofu, some semi-hard cheeses and preserved fruit and vegetables
- Lecithin (E322) is used to emulsify certain ingredients together and as a preservative. It can be made from eggs or soya.
With the rise of veganism in recent years, many creative substitutions for eggs are appearing. In baking, eggs often act as a binder so try swapping them for mashed bananas or apple sauce. A mixture of water and flaxseeds or chia seeds also give bakes a cohesive texture. For meringues, try using aquafaba which is the liquid from cooked chickpeas. It might sound strange but the protein present in the water acts in a similar way to egg whites!
Milk is the cause of an allergy that is most often seen in young children. Many will grow out of it by the time they are five years old.
There are numerous ways milk can be used in food products from the obvious – butter, cheese, yogurt and cream – to the not-so-obvious. Many processed foods such as soups, sauces, crisps and meats contain ingredients made from milk.
Look out for:
- Milk powder in packet sauces and soups
- Casein, which is a protein in milk. It can be found as a thickener in non-dairy food products
- Lactose is a type of sugar found in milk. Watch out for it in breakfast cereals, bread, salad dressings and other processed foods
- Whey – this is another protein in milk and can be in baked goods and salad dressings.
Obvious substitutions might appear to be sheep or goat’s milk. However, these contain similar proteins to cow’s milk so may not be suitable for those who are allergic to the protein element in milk. It’s advisable to use plant-based milks, such as those made from oats, rice or soya. Some of these milks are particularly effective in hot drinks and have similar frothing powers.
Although not as common as an allergy to milk or eggs, soya can still cause a serious reaction in allergy sufferers so it’s one to look out for.
Soya comes in many forms and is used widely across multiple cuisines and food types. According to Allergy UK, soya is used in up to 60% of manufactured foods. As well as the obvious culprits such as soy sauce, soya milk and margarine, there are lots of hidden sources of the protein.
Look out for:
- Soya lecithin, concentrate and isolated soya protein are used as emulsifiers or stabilisers in many processed foods such as ice cream, meat and bread
- Edamame – these are fresh soya beans
- Bean curd, tofu, miso paste and textured soya protein.
As soya is found in a lot of processed foods, the best way to avoid it is to create meals from scratch using fresh ingredients. Soy sauce can be replaced with products such as Maggi Liquid Seasoning.
