Dates are considered high energy nutritional fruits as they are packed with plenty of
minerals, vitamins and sugars. Among various options available for processing and value addition,
dry dates are one of the best possible alternatives to convert doka/khalal stage fruit into a high
value product. However, the technology for their production is limited to a few traditional date
growing countries and research is limited in the countries with expanding areas. Thus, the protocol
for development of dry dates was standardised and the effect of different blanching intervals (5, 10
and 15 min) on the drying and quality parameters were studied. The rate of drying, dehydration
ratio and rehydration ratio were found to increase with increasing hot water dipping durations
while a 10 min hot water dip was found to be best for retaining the best sensory parameters of taste,
colour/appearance and flavour. The total colour difference (∆E) was also maximal (71.10) in the date
fruits exposed to a 10 min dip treatment. The reducing sugars decreased and non-reducing sugars
increased with increasing hot water dipping periods while there was no significant variation in the
total sugar content of the treated dates. The tannins responsible for acrid taste were also reduced to a
minimum (1.43%) compared to control (2.52%) fruits. Thus, the fruits of date cv. Medjool being bulky
and fibrous with more dry matter content are well suited for dry date preparation.
