In addition, the prices of these unauthentic Harumanis mangoes are five times cheaper than the Harumanis mango itself and this fact entices errant traders to replace the Harumanis with the Tong Dam to gain bigger profits. According to the Perlis Department of Agriculture, Tong Dam and Susu mangoes are often used to deceive consumers because these mangoes have physical characteristics that are almost identical to the Harumanis mango, as shown in Figure 1, and therefore are called unauthentic Harumanis. ![]() The media has constantly reported the unethical activities of sellers who substitute the Perlis premium Harumanis mango with cheaper mangoes (Tong Dam and Susu) to gain fraudulent profits. Due to its high price and popularity, the Harumanis has become the target of economic adulteration involving substitution and misinterpretation. The Harumanis is often highly valued not only because of its delicious taste, but also because it is considered to be rare and limited and can only be found in Perlis, Malaysia, and Surabaya (Indonesia). In Malaysia, the exotic aroma of the Harumanis mango (MA128) has become the trademark of the fruit and is prized by many consumers. In addition, three ocimene compounds, namely beta-ocimene, trans beta-ocimene, and allo-ocimene, can be considered as chemical markers of the Harumanis mango, as these compounds exist in all Harumanis mango, regardless the different sources of the mangoes obtained. These techniques were successful in identifying the grouping tendencies of the mango samples according to the presence of their respective volatile compounds, thus enabling the identification of the groups of substances responsible for the discrimination between the authentic and unauthentic Harumanis mangoes. On the other hand, chemometrics techniques, such as principal components analysis (PCA), hierarchical clustering analysis (HCA), and discriminant analysis (DA), were used to visualise grouping tendencies of the volatile compounds detected. Prior to the analytical method, two simple sensory analyses were carried out to assess the ability of the consumers to differentiate between the Harumanis and Tong Dam mangoes as well as their preferences towards these mangoes. The VOCs of these mangoes were extracted and analysed nondestructively using Head Space-Solid Phase Micro Extraction (HS-SPME) coupled to Gas Chromatography-Mass Spectrometry (GC-MS).
