Randomized trial evaluates lipid deterioration in horse mesenteric fat, indicating rapid quality decline under stress storage conditions.

This study aims to characterize the oxidative and hydrolytic deterioration of raw horse mesenteric fat under sub-optimal storage conditions.
Subjected mesenteric fat from ten free-grazing horses to accelerated storage at 30 °C and 70% humidity for six days.
Evaluated physicochemical parameters including acid value, peroxide value, refractive index, density, melting point, and sensory attributes.
Conducted Fourier-transform infrared attenuated total reflectance spectroscopy at intervals of 0, 3, and 6 days.
Acid value increased from 1.17 ± 0.46 to 32.60 ± 26.18 mg KOH/g by day 6, exceeding the threshold of 2.0 mg KOH/g.
Peroxide value progressively rose throughout the storage period.
Density declined and melting point decreased significantly between days 0 and 3.

Nurseitova et al. (2026) studied this question.
