Systematic Review on Volatile Profile Compound and Its Application in Species Identification for Halal Authentication

Abstract

Volatilomic is an emerging research area where its rapidness and accuracy in its diagnostic ability have been reported to be promising and also is economically favorable. Meat and meat-based food produces certain composition of volatile compounds which can be utilized in identification of its origin and consequently be used for food authentication. Systematic literature review on various publications was done to evaluate the use of volatiles in identification of meat-based food. This review focuses on the volatile profile compounds, various factors which could affect its production, its extraction and detection method, and its application in meat and meat-based food with a brief background discussing on the possibility on its utilization for halal authentication. The result shows that major component of volatile compounds associated with the aromas of meat are of from aldehydes, ketones and alcohols with each of type of meat having variation in its composition. There is no definite pattern. Most of these volatile compounds are the products of combination of Maillard reaction, Stecker degradation, or interaction of both, as well as thiamine degradation. Commonly used extraction method for meat samples is HS-SPME (Head Space-Solid Phase Microextraction) as it is solventless, having high sensitivity and practical. Main analysis method for detection of the metabolites volatile compounds is Gas Chromatography-Mass Spectrometry and is the most superior out of other method options. As for Halal authentication, there is a potential and possibility of utilizing volatile compound profile of meat species for such purpose but not enough evidence or scientific study to entirely rely on it alone. Therefore, require a further validation technique such as PCR. Further studies need to be conducted revolving utilization of meat volatile compound profiles for halal authentication.
