Abstract
Harumanis’ (Mangifera indica L) is one of the mango cultivars which has high market value because of the excellent quality of the fruit which has attractive color, good aroma, delicious taste and high nutritive values. In this study, fifty accessions from five different collection sites which belonging to North (Paya Kelubi and Chelong Balik Bukit, Padang Besar), West (Santan, Kangar), East (Alor Ara Timur, Arau) and South (Simpang Empat, Kangar) region of Perlis were analyzed according to flesh color traits based on their region of origin. The analysis of variance using Kruskal-Wallis test resulted in significant differences among the geographical region for traits of fruit flesh color such as L*, a*, chroma and hue at (P<0.05). The correlation result shows that the intensity pattern of the orange color of the fruit samples mesocarp was associated by an increase in the values of a*, b* and C*, and a decrease in the values of L* and h. By performing Cluster analysis using Ward’s method and Euclidian distance, five distinct clusters were successfully identified. The finding shows a high distribution of ‘Harumanis’ accessions from different locations in each distinct group. This study also reveals the relationship of variability in fruit traits with their places of origin. However, these differences cannot be explained in firm via morphological characterization only. Other methods such as molecular characterization are strongly recommended.
Highlights
Color is a vital parameter for food quality indicator since it is able to influence the consumer perception in term of flavor, sweetness and elicit human emotional feelings
Since mango is a climatic fruit, this factor is postulated to play an important role in its carotenoid accumulation
It can be postulated that the hot climatic condition is favourable for β-carotene accumulation and can further result in fruit color variation which basically varies based on the origin of the mangoes
Summary
Color is a vital parameter for food quality indicator since it is able to influence the consumer perception in term of flavor, sweetness and elicit human emotional feelings. In the case of mango, epidermis color plays an important role in the perception of overall quality and is associated with the determination of appropriate maturity for harvest. One of the main factors which contribute towards the yellow-orange color of mango epidermis and mesocarp is carotenoids. Β-carotene has been emphasized as the main component that is interrelated with flesh color and resulting vitamin A values (Golob et al, 2012). The climatic condition has been stated as one of the major factors in the determination of accumulation of carotenoid. Since mango is a climatic fruit, this factor is postulated to play an important role in its carotenoid accumulation. It can be postulated that the hot climatic condition is favourable for β-carotene accumulation and can further result in fruit color variation which basically varies based on the origin of the mangoes
