Maininnovationand potentials
Innovation consists of
• New product date-set-syrup
• very appealing in terms of color, texture and spread-ability
• Processing conditions
• Optimum temperature of sugar crystallization, developingseeds, seed-syrup mass ratio, mixing methods andcrystallization time

• The new innovative processing method could be used
By the date-processing industry to produce a new product as Date-Set-Syrup.
• Will have high market value as compare to the syrup.
• Could diversify the product lines of the date fruits and will be economic beneficial to the date fruit industry.
