L-malic acid is an important intermediate in the citric acid cycle and plays a crucial role in energy metabolism. As a natural plant extract, L-malic acid has antimicrobial properties, is involved in lipid metabolism and regulates myoglobin redox. Sodium malate washing solutions have been shown to be effective in reducing Salmonella levels in chicken breasts and extending product shelf life. A study showed a negative correlation between muscle malic acid and obesity in rabbits. I Increased number of oxidized muscle fibers in piglets fed L-malic acid during weaning improved the water holding capacity of pork without any effect on carcass traits. This case study examines the effects of dietary L-malic acid supplementation on meat quality and carcass traits in fattening pigs and its potential mechanisms. The following figure demonstrates the effect of dietary supplementation of L-malic acid on myofiber type composition of LD muscle ( n = 8).

Effects of dietary supplementation of L-malic acid on quality, antioxidant capacity and muscle fiber characteristics of fattening pork (Enfa Yan, et al., 2022)
