Application of advanced instrumental methods for yogurt analysis.

Compared to the classical methods of analysis, advanced instrumental methods have received increasing attention due to their highly precise analysis of food micro-/macro-structure. Due to its widespread popularity, yogurt has been the subject of numerous studies. This article discusses major advanced instrumental methods applied to the analysis of set/stirred yogurt reported in the literature. Discussed analytical methods have been categorized into two parts, namely chemical analysis methods (including flavor analysis of yogurt, analysis of milk constituents, and assays of indexes), and structural analysis methods (including textural and rheological analysis as well as microstructural analysis).
