Syrup:
Syrup is sweet, viscous, concentrated or nearly saturated aqueous solution of sucrose
containing 66.7%w/w of sugar.
Methods of preparation of syrup.
1. Simple solution method
2. By process of extraction.
3. By Chemical interaction
Method of preparation
1) By simple solution method e.g. simple syrup or ginger syrup Add sucrose to purified
water and heat to dissolve sucrose with occasional stirring cool and than add water to
make required weight.
2) By process of extraction e.g tolu syrup Add boiling purified water to tolu balsam, cover the vessel lightly and boil the content for half an hour stirring frequently add purified
water to adjust the specific weight ,cool and filter the solution add sucrose and dissolve by
add of heat.
(3)Syrups made by chemical reaction e.g. comp syrup of ferrous phosphate In this
preparation the reaction takes place between iron wire and phosphoric acid result in
formation of ferrous phosphate reaction also takes place between calcium carbonate
potassium bicarbonate and phosphoric acid resulting in formation of corresponding
phosphate salts after the reaction is complete add sucrose and flavouring agent than adjust
the volume with purified water.
