Dates offer validated antioxidant benefits for functional snack bars, improving formulation options
New Saudi research validates dates as a superior base ingredient for functional snack bars, demonstrating significant postprandial antioxidant capacity and reduced oxidative stress compared to other fruit bases. This offers manufacturers a cost-effective, nutrient-dense ingredient for next-generation product development.

Riyadh, Saudi Arabia — 24 June 2024
A recent Saudi-funded study highlights dates as an effective base ingredient for functional snack bars, leveraging their significant bioactive compounds, high nutritional content, and robust antioxidant capabilities. This research provides a clear commercial advantage for manufacturers seeking to enhance product efficacy and natural ingredient profiles within the rapidly expanding functional snack market.
The randomised cross-over study, funded by the Deputyship for Research and Innovation, Ministry of Education in Saudi Arabia, compared the impact of a date-based bar (DBB) against a fruit-based bar (FBB) on antioxidant status. Twenty healthy male participants consumed 140g portions of both bar types, with specific attention to post-consumption changes in total phenolic content (TPC), total antioxidant capacity (T-AOC), and malondialdehyde (MDA) concentration – a key biomarker for oxidative stress. This direct comparison offers actionable data for product developers.
Results indicated that ingesting the date-based bar significantly increased TPC and T-AOC within 120-180 minutes post-consumption. Crucially, a significant decrease in MDA content was observed 180 minutes after DBB consumption, while the FBB showed no significant change. Furthermore, DBB ingestion led to an effective increase in superoxide dismutases (SODs) – vital antioxidant enzymes – within 120 minutes, a response not seen with the FBB. This superior antioxidant profile for dates provides a clear value proposition for new product development.
Dates, rich in phenolic acids, polyphenols, and carotenoids, possess documented functional and pharmacological advantages. Specific varieties like Sukkari, Mabroom, and Khalas contain flavonoids such as quercetin and luteolin, known for reducing lipid peroxidation and improving antioxidant capabilities. The study underscores dates as a nutrient-dense, applicable, convenient, and cost-effective ingredient, potentially offering a better natural sugar alternative for calorie needs. This positions dates as a strategic ingredient for manufacturers looking to formulate next-generation functional foods with clear scientific backing.
What this means for United Kingdom
UK manufacturers and brand owners should immediately evaluate dates as a core ingredient for functional snack bar lines, capitalising on verified antioxidant benefits. This presents a clear opportunity to reformulate existing products, improving natural ingredient profiles and strengthening health claims, particularly around 'active' or 'recovery' formulations. Procurement teams should explore direct sourcing from major date-producing regions to optimise raw material costs. Brand differentiation can be achieved by highlighting the scientifically backed antioxidant properties of date-based bars, appealing to health-conscious consumers in the competitive UK functional food market. Compliance teams must ensure claims align with EFSA guidance for antioxidant ingredients, leveraging specific data points from the study.
The study, published in Nutrients, acknowledged limitations, including a small sample size and a young demographic. Future research with extended observation times and broader demographic representation is recommended to further validate these findings, particularly as oxidative stress varies with age.
