SYMPLE SYRUP
TO PREPARE SYMPLE SYRUP 100g
- Theory: Syrups are concentrated oral solutions of sugar or nearly saturated solutions of sucrose in water or other aqueous liquids. Syrups containing 85% w/v or 66.7% w/w sucrose will retard the growth of microorganisms. Dilute solution of sucrose provides an excellent nutritional media for the growth of yeast, moulds and other microorganisms. When heat is employed for the preparation of syrups, a small portion of sucrose changes to dextrose and levulose. This phenomenon is called as inversion. Sucrose solution is optically active and rotates polarized light to right while on heating optical activity decreases rotated the light to left due to formation of other compounds (dextrose ad levulose). The rate of inversion is enhanced by the presence of acids and hydrogen ions, which act as catalyst.
- Syrups are mainly of three types:
- 1. Simple Syrup: It contains sucrose in purified water alone or in combination of other polyols such as glycerin or sorbitol. These substances are added in syrups to reduce the crystallization of sucrose or improve the solubility of excipients.
- 2. Medicated Syrup: It contains some added medicinal substances in the syrups and used for therapeutic pur pose, e.g. ephedrine sulphate syrup.
- 3. It contains various aromatic or plea santly flavored substances but are non-medicated and generally used as vehicle or as a flavoring agent or for preservation.
- Sucrose syrup is a sweet, viscous, concentrated aqueous solution of sucrose or other sugars in water or any other suitable aqueous vehicle. They are used as sweetening and flavouring agents. Examples are Lemon syrup, raspberry syrup, tolu syrup etc.
- Syrup is used for the following purpose:
- 1. Syrup retards oxidation.
- 2. It prevents decomposition of many vegetable substances. 3. They are palatable.
- Materials: Measuring cylinder, beaker, and glass rod.
- Reagents: Sucrose, Distilled water.
- Procedure:
- 1. Take a required quantity of sucrose.
- 2. Add 3/4th volume of water and stirred till all the sucrose dissolve.
- 3. Finally add water to make up the required quantity.
