Abstract

The effects of ultrasonic-assisted glycosylation technology on the gel properties of transglutaminase-induced peanut protein isolate (PPI) and its influence on the release behavior of riboflavin were investigated. The mechanism of the glycosylation action and polysaccharide content on the gel properties of PPI were preliminarily explored. The results showed that glycosylation action made the structural unfolding of PPI, enhanced the molecular interactions between molecules, and formed a more compact gel network structure. Especially when the ratio of PPI to corn silk polysaccharide was 5:1, the G', G", gel strength, and water-holding capacity were significantly improved. The improvement of gel properties was related to the hydrophobic interaction and disulfide bond enhancement between PPI and corn silk polysaccharide. Glycosylation action made the composite gel had a higher loading rate and protective and sustained release of riboflavin. This study provided an idea to solve the problems of poor processing performance of PPI.

期刊介绍： Food Chemistry: X, one of three Open Access companion journals to Food Chemistry, follows the same aims, scope, and peer-review process. It focuses on papers advancing food and biochemistry or analytical methods, prioritizing research novelty. Manuscript evaluation considers novelty, scientific rigor, field advancement, and reader interest. Excluded are studies on food molecular sciences or disease cure/prevention. Topics include food component chemistry, bioactives, processing effects, additives, contaminants, and analytical methods. The journal welcome Analytical Papers addressing food microbiology, sensory aspects, and more, emphasizing new methods with robust validation and applicability to diverse foods or regions.
