Mango Seed Kernel Fat as a Cocoa Butter Substitute Suitable for the Tropics.

Cocoa butter is a key ingredient in many chocolate products but its partial substitution with mango (Mangifera indica L.) seed kernel fat (MSKF) has the potential to reduce chocolate production costs and improve shelf-life. Here, MSKF was extracted from three cultivars of mango grown in Pakistan: Lal Badshah, Anwar Retual, and Chaunsa. Physicochemical and antioxidant properties of the MSKF samples were studied at 0, 30, and 60 days of storage at 30 °C, a temperature reflecting typical storage conditions in the tropics. Overall, the Lal Badshah MSKF had the most favorable physicochemical properties, including the highest DPPH antioxidant activity among the three cultivars. Thus, Lal Badshah MSKF was used to formulate cocoa butter substitute chocolate (CBSC), substituting the cocoa butter at 20 to 80 g/100 g. CBSC had a lower value for hardness (3.80 N) compared with the control chocolate (4.42 N). Color values L , a , and b were not significantly affected by the different rates of substitution or by length of storage. Oxidative stability and antioxidant potential of CBSC increased with both higher substitution levels of MSKF and length of storage. The results suggest that MSKF can be utilized as a cocoa butter substitute at levels up to 60 g/100 g. This potential for substitution is particularly valuable for tropical regions where refrigerated storage may not be available or financially viable. PRACTICAL APPLICATION: Mango seed kernel fat (MSKF) has potential to be used as a cocoa butter substitute in confectionery products, particularly chocolate. The mango industry could utilize fat extraction from mango seeds, which are normally a waste product, for value adding.
