Formulation, standardisation, proximate composition and shelf life analysis of palm date seeds (Phoenix dactylifera) coffee powder

Abstract

Background: Prevalence of coffee addiction is increasing among the people in day to day life. The caffeine content in the coffee will help the people to wake up quicker but not healthier. Over consumption of coffee will also cause some health effects like increased blood pressure, insomnia, etc. Thus, in order to provide a healthy alternative, coffee beans have been replaced with palm date (Phoenix dactylifera L.) and some flavouring ingredients are also added for enhancing its Flavour and aroma. Date seed coffee powder contains high level of phenols and it is caffeine free which would be an healthy alternative for the daily consumption. Methodology: The current coffee powder has been replaced with date seed powder and some other ingredients like plantain leaves, mint, ashwagandha and cardamom has been added. All the ingredients were dried and powdered in three variations. And it was organoleptically evaluated by 20 panel members. Based on the high acceptability, one of the variations was chosen and it was assessed for proximate composition and shelf life of the product. Then it was statistically analysed by using Analysis of Variance (ANOVA). Results: The sensory scores revealed that variation III has higher mean score and was highly acceptable. The nutritional analysis of the product provided that it was caffeine free and has all the other essential nutrients like carbohydrate, energy, protein, fat, phenols, tryptophan and caffeine. The product has good shelf life of about 11 months from the date of manufacturing. Conclusion: Date seeds proved to be a healthy alternative for regular coffee which is caffeine free. Date seed coffee is a healthy nutrient rich coffee which could be suitable for daily consumption.
