Abstract

Abstract:

As one of the high-quality organic trace elements, polysaccharide trace element complexes have attracted the attention of domestic and foreign researchers because of their excellent biological functions of polysaccharides, and can significantly increase the utilization of trace elements and reduce environmental pollution. This review outlines the state-of-art research advances in plant, alga, and microbial polysaccharide trace element complexes. We emphasized the influence of molecular structure of the polysaccharide on the process conditions for complex synthesis and the potential application of polysaccharide trace element complexes in the feed industry. Meanwhile, challenges faced by polysaccharide trace element complexes and corresponding solutions are discussed. Overall, this review is intended to provide valuable insights for the synthesis of polysaccharide trace element complexes from a biochemical engineering standpoint, promoting the combination of green agricultural development and green livestock products.

Key words: polysaccharides, trace element, complex, synthesis, feed
