摘要： Trimethylamine (TMA), which is known to severely affect consumer acceptance and application, is the main compound of sea cucumber intestinal peptides. Herein, different V-type crystalline starches (V-6a/h, V-7a/h, V-8a/h) were prepared using high amylose maize starch for the adsorption of TMA. After analyzing the structure of V-type starches, the V-8-type starch had a smaller and more evenly dispersed particles with additional surface pores and cracks, and reduced relative crystallinity compared with V-6- and V-7-type starch. The relative crystallinity of V-6a-, V-6h-, V-7a-, V-7h-, V-8a-, and V-8h-type starches was 59.1%, 51.8%, 42.7%, 41.3%, 40.4%, and 40.1%, respectively. Adsorption models for V-type starches and TMA helped to analyze the adsorption kinetics characteristics and investigate the effect of different V-type starches on adsorption. Moreover, its adsorption kinetics process agreed with pseudo-second-order kinetic model (R-2 > 0.96). Note that different V-type starches demonstrate good adsorption effects on TMA, and the removal rate is as follows: V-8h > V-8a > V-7h > V-7a > V-6h > V-6a. Herein, we used environmental protection and food-grade V-type starches to effectively adsorb TMA and ensure a theoretical foundation for enhancing the flavor and quality of functional seafoods.
