Single cell protein-feed: Taking orange waste as raw material for fermentation

This paper introduces orange waste as a promising substrate for microorganism fermentation to produce single cell proteins (SCP) which can be used for animal feed or human food. Firstly, the nutrition composition and physical features of orange waste, the composition of auxiliary material and the biomolecular composition of microorganisms are collected for analysis. Secondly, available data on fermentation conditions and parameters, possible application in animal feeds and the impact on animals are summarized; to demonstrate the feasibility of fermented orange waste as animal feed. Furthermore, the economic benefits and costs of SCP produced from fermented orange waste are discussed. Therefore, the development of fermented orange waste as animal feed has been comprehensively and systematically analyzed, laying a solid foundation for future commercial applications in the Three Gorges Reservoir Region.
