Interpretive Summary: Cottonseed protein can be obtained from cottonseed meal, which is widely available for use as animal feed, fertilizer, and other low-value applications. Although it is currently under-utilized for specialty and non-food applications, there have been many publications that provide promising information on its chemistry and possible applications. This article aims to provide a timely review of these developments. Hopefully it will stimulate further interest in expanding the utility of this widely available, sustainable, agro-based raw material.

Technical Abstract: There has been increasing interest in recent years on the use of agro-based raw materials for the production of bio-friendly and sustainable products. Plant-based proteins are among the popular materials being studied. In particular, cottonseed protein (a byproduct of cotton production) is widely available and has useful properties. Although not as well-known as soy protein, cottonseed protein has been shown to be a potentially valuable raw material for numerous applications. In this review, the latest developments in isolation, composition and molecular weight, chemical and enzymatic modifications, and non-food applications are delineated. Among these applications, films and coatings, interfacial and emulsifying applications, adhesives, and bioplastics seem to attract the most attention. A particular effort has been made to cover the literature on these topics in the past 10 years.
