Abstract:
Starch ghost, an insoluble structure of gelatinized starch, plays an important role in the applications of starch. In this review, we summarized the preparation, morphology, structure, properties and applications of starch ghost. The preparation steps of starch ghost include gelatinization, purification and preservation, and many factors influence the yield of starch ghost. The morphology and content of starch ghost can be influenced by many factors like starch resource and amylose content. Ghosts from non-waxy starches are composed of amylopectin with long branch-chains and amylose. These molecules cross-link to each other to reinforce the structure, and tend to form B-type double helix in ghosts from high-amylose starches. Some surface proteins that bind tightly to starch granules are also present in starch ghost. Protein and lipid are thought to have limited effects on the structural stability, but they make a big difference in the morphology of starch ghost. Starch ghost shows a different resistance to amylase among various starches, but it can be further digested under the high shear force. The mechanical, enzymatic hydrolysis and electrochemical properties of starch ghost make it widely used as emulsifier, stabilizer, thickener and starch-based films or gels in food and non-food processing industries.
