The inhibition effect and mechanism of typical hydrocolloids on the formation of heterocyclic amines: A study based on quantum chemical computation analysis.

Hydrocolloids, as thickeners, have been receiving increasing attention from researchers. Although they exhibit significant free radical quenching abilities, which demonstrate potential heterocyclic amines (HAs) inhibitory capabilities by blocking the free radical pathway, the inhibitory effect and mechanism are still unclear. This study investigated the effects of three typical hydrocolloids (alginic acid, chitosan, and carrageenan) on both free and bound HAs in fried meatballs, along with their mechanisms of free radical quenching using density functional theory.

Health effects of exposure to β-carboline heterocyclic amines: insight into metabolic perturbations and biochemical analysis.

As a class of bioactive and toxic compounds widely present in foodstuffs, the health effects of dietary exposure to β-carboline heterocyclic amines (HAs) have not been elucidated. Based on our previous research that a typical β-carboline HA (harmane) affects blood glucose metabolism and organ dysfunction, the present study mainly focused on the health effects of dietary exposure to harmane in diabetic Goto-Kakizaki (GK) rats. Twenty-four GK rats were administered daily with harmane (0.
