At this study, the meat of male wild ducks (Mallard) was used. After slaughter and cleaning, tenderization treatments were carried out with citric acid, which were as follows; A: Negative control treatment (soaking with distilled water only) for 24 hours. B: Positive control treatment (tenderizing with date vinegar at a rate of 100 ml/ liter of distilled water) for 24 hours. C, D and E were tenderizing treatment with citric acid at a ratio of 100, 200 and 300 ml per liter of distilled water for 24 hours. The results indicate that all tenderizing treatments with citric acid, led to a significant increase in water holding capacity, with a significant decrease on the drip and cooking loss compared to the negative control treatment, in addition to a significant increase on soluble collagen, with a significant decrease on the insoluble collagen and total collagen in the citric acid treatments compared to the two control treatments. A decrease in pH was observed compared to the negative control. In protein, there was a significant increase in citric acid treatments, as for the fat, there was a decrease in the level of significance. As for ash, there were no significant differences between A and B on the one hand, C and D on the other hand.
