Lupin on the menu: the allergen nobody expects

What it covers

Point 13 of Annex II of Regulation (EU) 1169/2011, still in force in the UK, covers “Lupin and products thereof”. There are no exceptions. Lupin joined the European allergen list through Directive 2006/142/EC, at the same time as molluscs, when lupin flour was already being used in bakery and pasta products. The FSA’s guidance adds that the rules do not name a particular species, so they apply to all lupins.

Every form of lupin counts:

• the cooked, brined seeds served as a snack;
• lupin flour;
• the lupin protein and fibre used by the food industry;
• products made from them, such as drinks, spreads and plant-based burgers.

Where it can appear

At the bar and the deli counter

• Lupini beans as a snack, on their own or mixed with olives and pickles.
• Antipasti and mezze platters.
• Mixed snacks served from the same bowl or with the same spoon.

Bread and baking

• Some breads, rolls, biscuits and pizza bases that use lupin flour for protein, colour or texture.

Gluten-free products

• Lupin flour is used in some gluten-free mixes to replace part of the wheat flour. That detail matters: the guest with coeliac disease who orders the gluten-free option may meet a different allergen.

Vegan and high-protein products

• Some plant-based burgers and mince, high-protein pasta, snacks and spreads such as lupin hummus.
• Some replacements for egg or soya in manufactured food.

Bought-in batters and coatings

• Some batter and coating mixes include lupin flour. The label will say so.

Why it gets forgotten so often

Hardly anyone cooks with lupin, so it is easy to think “we don’t have it here”. The real risk sits in two places:

1. The bar snack, served without going through the menu and easy to leave out of the allergen matrix.
2. Bought-in products, especially bread, gluten-free mixes and vegan products, which can contain lupin without the name suggesting it.

Look on labels for “lupin”, “lupine”, “lupin flour” or “lupini”, which must be emphasised in the ingredients list. Do it every time you change your bread or gluten-free supplier.

Lupin and peanuts

Lupin and peanuts are legumes from the same family, and some people allergic to peanuts also react to lupin. The FDA’s consumer advice highlights that risk. It is not your job to assess it, but it is your job to give complete information: mark the two allergens separately, each with its own number, and avoid serving lupini and peanuts in the same snack bowl. There is more on the peanuts page.

Cross-contamination

• Bowls and spoons shared between lupini, olives and other snacks.
• The brine from one container reused for another pickle.
• Snack mixes prepared together on the same tray.

If you cannot keep lupin apart from the other snacks, mark traces on the ones that share a container.

When a guest asks about lupin

It is a rare question, and that is exactly why it catches front-of-house staff off guard. A few rules for answering well:

• On each dish record, note the bought-in products that contain lupin or carry a trace warning: bread, gluten-free mixes, vegan products.
• Include bar snacks in your allergen information, even if they are not on the menu.
• If you do not have the label to hand, say you will check rather than guess.
• If a guest with a peanut allergy asks about lupin, give them the information for both. The decision is theirs.

In the US

Lupin is not one of the FDA’s nine major food allergens, so US labels carry no allergen “Contains” statement for it. It must still appear by name in the ingredient list, usually as “lupin” or “lupine”, and the FDA advises consumers with a peanut allergy in particular to look out for it.

How to mark it on your menu

Lupin is number 13 in Annex II. Mark it on the menu when it is in a dish and, even if it is not on the menu, include it in your premises’ allergen information if you serve it as a snack. A line for “bar snacks” in the allergen matrix answers a lot of questions.

MenuDesign treats lupin like the other thirteen: you mark it on the dish, it appears with its icon or the number 13 and goes into the key and the matrix. To review all fourteen at once, see the full list in the 14 allergens.
