Abstract:

Litopenaeus vannamei has been widely used in the food industry due to its excellent nutritional value and
delicious taste, but unfortunately, consumption of Litopenaeus vannamei can cause allergic reactions in some people.
Therefore, it has gained growing attention from many researchers. In this paper, the properties, composition, spatial structure,
and allergic epitopes of four kinds of allergens including tropomyosin (TM), arginine kinase (AK), myosin light chain (MLC)
and sarcoplasmic calcium-binding protein (SCP) with molecular weights between 20 and 80 ku are reviewed. This paper will
be useful for a better understanding of the mechanisms of these allergenic proteins and reduction of their allergenicity.

Key words: Litopenaeus vannamei, allergen, structure, characters
