Abstract:
As a significant component of agricultural and forestry biomass, hemicellulose is an abundant resource, biodegradable, nontoxic, environmentally friendly, and has good biocompatibility. Hemicellulose's structural variability - arising from diverse sugar compositions, branching patterns, different molecular weights, and degrees of polymerization across plant sources - significantly impacts hemicellulose performance in applications. Therefore, modifying hemicellulose to produce hemicellulose derivatives and enhance its comprehensive application value has attracted widespread attention. This article discusses three leading modification technologies: physical, chemical, and biological. The modification of hemicellulose alters its structure, improving both its hydrophilic and hydrophobic properties, thereby enhancing its emulsifying ability. It also highlights that different modification methods correspond to different structure-property relationships, and these studies can lead to a variety of applications in the food industry.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
