Biological surfactants are a class of amphipathic biomolecules that contain a
diverse range of constituents derived from different biological sources and have been
analysed for their ability to lower surface tension. Their distinct properties with
cumulative applications have expanded in different fields starting from human health to
detergent industry. According to estimates, the global market for biosurfactants will
grow from $4.18 billion in 2022 to $6.04 billion by 2029. Biosurfactants outperform
artificial surfactants due to their unique attributes. This provides opportunities for
commercial utilization of biosurfactants. Thus, the present chapter aims to describe the
various biosurfactants present in the market along with their potential application in
food industries.
