Article Synopsis
- - The study explored creating antioxidant peptides through enzymatic hydrolysis of bone collagen, utilizing microwave-assisted acid pre-treatment and nitrogen protection.
- - Phosphoric acid was identified as the most effective hydrolyzing agent, achieving a highest degree of hydrolysis (9.5%) under specific conditions involving microwave intensity and time.
- - The use of neutral proteinase yielded better results than other proteases, with optimal conditions determined, and the antioxidant capacity peaked at 3 hours of hydrolysis before declining.

Objective: To monitor the biological levels of environmental endocrine disruptors (EDs, phthalates and surfactants) in the umbilical cord blood and maternal blood of low-birth-weight infants.
Methods: All 30 umbilical cord blood samples and 21 maternal blood samples were collected from low-birth-weight infants. The concentration of four kinds of phthalates (di-2-ethylhexyl phthalate, DEHP; mono-2-ethylhexyl phthalate, MEHP; di-ethyl phthalate, DEP; di-n-butyl phthalate, DBP) and two kinds of surfactants (4-nonylphenol, 4-NP; octylphenol, OP) in these blood samples were measured by using reversed-phase high performance liquid chromatography.
