What does acidity of extracted fat denotes in biscuit?

The acidity of extracted fat in biscuits indicates the quality and freshness of the fat used in the formulation. Higher acidity levels can suggest the presence of free fatty acids, which may result from lipid degradation or rancidity. This can adversely affect the flavor, texture, and overall shelf life of the biscuits. Monitoring fat acidity is crucial for ensuring product quality and consumer acceptance.
