Lupin flour

Lupin flour is made from the legume of the sweet lupin, and is therefore related to other legumes such as peanuts and soybeans. The European white lupin has been eaten as a food by humans dating back to the ancient Egyptians, but use of the sweet lupin is relatively recent.

Lupin flour is high in protein, essential amino acids and fibre, is easily digestible, low GI, cholesterol free, an appetite suppressant, and wheat/gluten free.

Usage:

Lupin flour can be used in gluten free baking, and like most gluten free flour alternatives, is best blended with other flours. However it does come with an allergy caution as it is from the same legume family as peanuts and soybeans. Anyone with an allergy to peanuts, legumes or soybeans should avoid eating lupin flour.

The FDA has issued an allergy warning about lupin flour for people with peanut or legume allergies:

Storing:

Like many alternative flours, lupin flour is best stored in an airtight container in the fridge, or in the freezer. If refrigeration or freezing is not available, then store in a cool, dark cupboard, and use within its use by date.

Alternative names/types:
