Abstract
Nowadays, with the increasing popularity of functional natural products, scientists have begun to study propolis in more detail and use it in many products from health to food, from food to cosmetics. The raw propolis is a resin-like product used as a disinfectant, structure, and defense agent in the hive, collected by bees (Apis mellifera) from plants. Propolis demonstrates anti-inflammatory, antioxidant, and antibacterial effects due to the bioactive compounds it contains. The strong aroma, stickiness, and low water solubility of the raw propolis limit its use in many fields. The active ingredients of propolis obtained by extraction method are used as food supplement in pure form, as well as to increase functional value of various foods. In this review includes novel processing techniques that increase the solubility and bioavailability of raw propolis, the use of propolis extract in the food field, and its safe levels of intake.
