Fortification of chocolates with high‐value‐added plant‐based substances: Recent trends, current challenges, and future prospects

Abstract

AbstractHigh consumption of delicious foods, such as chocolates, is considered excellent snacks, capable of converting from health‐threatening to great functional foods. The fortification of chocolates with high‐value‐added plant‐based substances might improve their healthful effects, nutritional properties, and shelf life. Chocolate could be an effective carrier for plant‐based substances delivery, and it could be an effective vehicle to treat and reduce the indications of disease, such as obesity, overweight, hypertension, stress, cardiovascular failure, congestive heart failure, and diabetes. Referring to the recent studies in chocolate fortification with high‐value‐added plant‐based substances, it seems that the recent trends are toward its therapeutic effects against noncommunicable diseases. Despite the undeniable functional effects of fortified chocolates, there are some challenges in the fortification way of chocolates. In other words, their functional characteristics, such as rheological and sensory attributes, may undesirably change. It seems that encapsulation techniques, such as spray drying, antisolvent precipitation, nanoemulsification, and liposomal encapsulation, could almost overcome these challenges. Thus, several studies focused on designing and fabricating nanoscale delivery systems with the aim of chocolate fortification, which is discussed.
