In long-shelf-life yoghurt, the concentrations of butanoic acid and hexanoic acid showed an increasing trend with increasing acidity levels, presenting significantly higher levels in Batch H (P ≤ 0.05).
In long-shelf-life yoghurt, the concentrations of butanoic acid and hexanoic acid showed an increasing trend with increasing acidity levels, presenting significantly higher levels in Batch H (P ≤ 0.05).
Conversely, the concentration acetic acid showed a decreasing trend, indicating a potential conversion of acid compounds ( Zhao et al., 2022 ).
