Dates: a nutritional powerhouse for functional energy bars

This review explores the significant potential of date palm fruit (Phoenix dactylifera) in creating functional energy bars, highlighting their chemical, nutritional, functional, and sensory properties. Date fruits are highly nutritious, offering an array of macro- and micronutrients known for their bioactive properties. These include antioxidants, anti-inflammatory agents, and compounds with anti-tumor, antihypertensive, and antimicrobial activities. Such attributes make dates an exceptional ingredient for developing energy bars.
Date-based energy bars utilize date paste as a primary ingredient, ranging from 55-90%. The addition of protein sources, typically skim milk powder, helps balance the high carbohydrate content of dates with essential proteins. This results in protein-rich snack bars that maintain favorable sensory attributes. Furthermore, incorporating cereals or legumes can enhance the nutritional profile by adding fiber and improving texture. Studies have shown that the inclusion of dry ingredients like cereals significantly lowers moisture content, which reduces fracturability and enhances shelf-life stability by limiting microbial growth. Additionally, adding bioactive or functional ingredients such as fruit peels, seeds, or plant extracts can boost phenolic or flavonoid content, further enhancing the antioxidant potential of the bars.
Given the growing global demand for convenient, nutrient-dense snack options, date-based energy bars are poised to gain significant consumer acceptance. Their balanced nutritional profile and extended shelf life make them an excellent choice for health-conscious individuals seeking functional snacks.
