Abstract
ABSTRACTThe objective of this study was to verify key aroma‐active compounds responsible for reconstituted fresh skim milk powder (SMP) aroma using threshold analysis, odor activity values, and model systems. Twelve odor‐active compounds of SMP and one odor‐active compound from fluid milk were selected based on flavor dilution factors from gas chromatography‐olfactometry. Thresholds for the 13 odor‐active compounds were identified using five‐set ascending forced choice threshold analysis in odor‐free water and fluid skim milk. Model systems were prepared using rehydrated milk retentate (RMR). The aroma of each model was evaluated by descriptive sensory analysis and by difference‐from‐control testing using a trained panel. The aroma of reconstituted fresh SMP and liquid skim milk were used as controls. Models containing a mixture of twelve of the thirteen chemicals had the most similar odor characteristics to rehydrated SMP aroma (9.0/10) indicating that these compounds constitute the character impact odorants of rehydrated fresh SMP.
